First Words<br />

Taking the rough with the smooth<br />

Pang Yanrong<br />

Senior Editor<br />

With COVID-19<br />

rapidly travelling<br />

around the globe, the<br />

WHO (World Health<br />

Organization) has<br />

now considered the<br />

virus a pandemic (as<br />

of this writing).<br />

The effects felt has been unprecedented —<br />

with countries on lockdown, cruise ships<br />

quarantining their passengers and crew<br />

members, and events being postponed. For<br />

instance, exocad Insights <strong>2020</strong> has moved<br />

from mid-<strong>March</strong> to the second half of the<br />

year. IDEM (International <strong>Dental</strong> Exhibition<br />

and Meeting), which was planned for <strong>April</strong>,<br />

has been postponed to June.<br />

But as the world grapples with the changes<br />

COVID-19 brings, there are still the movers<br />

and shakers in the industry who are making<br />

the best of the situation. Take for instance,<br />

Henning Müller, group vice president of <strong>Asia</strong><br />

Pacific RCO at Dentsply Sirona, who sees <strong>Asia</strong><br />

Pacific as the future for growth (p.26).<br />

“Many markets across <strong>Asia</strong> are becoming<br />

increasingly important, not only as<br />

emerging markets, but also as trendsetters<br />

as they continue to mature. To tap into<br />

the growing potential of the region,<br />

and connect better with local dental<br />

professionals, Dentsply Sirona opened a<br />

showroom in Singapore’s Post Centre, as<br />

well as a state-of-the-art training centre<br />

and showroom in Hong Kong in 2018,”<br />

he revealed.<br />

Prof. Dr. Juergen Manhart and CDT Hubert<br />

Schenk continue to bring great smiles to<br />

people despite the situation. They shared<br />

how they had to do an anterior full crown<br />

after a complicated fracture of a natural<br />

tooth (p.34).<br />

Dr. Douglas G Watt also shared his<br />

experience with a female patient who<br />

had came in requesting for orthodontic<br />

treatment and restoration of her dentition,<br />

which he succeeded in doing so with<br />

3Shape TRIOS Design Studio (p.54).<br />

“The use of 3Shape TRIOS scanner and<br />

TRIOS Design Studio software as part of the<br />

continuous and seamless workflow, along<br />

with the direct integration with DGShape,<br />

is an easy and predictable option for inhouse<br />

manufacture, and same day crown<br />

workflow. The update to allow use of TRIOS<br />

Patient Specific Motion made this case even<br />

more predictable as the patient’s actual<br />

excursive and protrusive movements can<br />

be utilised rather than a virtual articulator,”<br />

he said.<br />

And then there’s Guido Testa who came up<br />

with the idea of using sandblasting as an<br />

alternative to cutters or burs (p.58), and<br />

Dr. Kevin Ng who shares about the three<br />

dental instruments that have been useful<br />

for him at his practice (p.24).<br />

As we continue our fight with COVID-19,<br />

I hope everyone stays safe during this<br />

period, and please continue to often wash<br />

your hands with soap and water so as to<br />

reduce the spread of the virus and other<br />

infectious diseases!<br />

exocad will continue to operate as it exists<br />

today, and co-founders Tillmann Steinbrecher<br />

and Maik Gerth, along with their team, are<br />

expected to remain after the transaction<br />

closes.<br />

“The acquisition of exocad adds a talented<br />

and passionate team as well as a highly<br />

innovative, industry-leading product suite<br />

Technology’s senior vice president and CFO.<br />

“We will continue to invest in and build on<br />

exocad’s leadership in the dental CAD/CAM<br />

market and look to them to make significant<br />

contributions to Align’s overall strategy.” ■<br />

exocad Insights moves dates to 21 - 22 September, <strong>2020</strong><br />

Due to the spread of the coronavirus<br />

worldwide and increasing travel restrictions,<br />

exocad GmbH has decided to postpone the<br />

Insights <strong>2020</strong> event, originally planned for<br />

mid-<strong>March</strong>, to 21 st – 22 nd September. The<br />

venue remains unchanged at darmstadtium<br />

in Darmstadt, Germany. The decision is also<br />

supported by the 43 cooperation partners.<br />

“The safety and health of our participants,<br />

partners and employees is our top priority,”<br />

explained Novica Savic, CCO of exocad.<br />

Insights <strong>2020</strong> focuses on the almost limitless<br />

possibilities of exocad’s open software<br />

platform, on which intraoral and model<br />

scanners, milling machines, 3D printers and<br />

DVT devices from different manufacturers<br />

can be combined to form a consistent digital<br />

workflow. ■<br />

An evening with dinner and live music will round off the event in the<br />

festive presence of the approximately 850 international participants<br />

The two-day event, which is aimed at both dental technicians and dentists, offers a varied<br />

programme consisting of software education, partner sessions and international guest<br />

speakers<br />

Modern and Intuitive: Double Triple for W&H Design<br />

When man meets machine, user-friendly operation plays a crucial<br />

role. For Austrian company W&H, this is precisely where the focus<br />

lies when designing medical technology products. W&H’s designs<br />

have succeeded in winning over not one but two international juries,<br />

with three products winning prizes at the Good Design Award 2019<br />

in the USA and the German Design Award <strong>2020</strong>.<br />

They fit perfectly in the hand, are intuitive in their operation, provide<br />

optimal freedom of movement and also look great: these are the<br />

main reasons why W&H products — Proxeo Ultra, Proxeo Twist<br />

Cordless and Assistina Twin — were awarded two internationally<br />

renowned Design Awards.<br />

Proxeo Ultra,<br />

Proxeo Twist<br />

Cordless, and<br />

Assistina Twin<br />

Head of W&H product design team, Kerstin Molzbichler, said, “When<br />

developing our products, our focus is firmly on the customer and<br />

their needs. Ultimately, our products are the interface between man<br />

and machine, between dentist and patient.<br />

Maria Protiwa-Kinzl, Nils Deringer, Kerstin Molzbichler, Kerstin Oberhofer, Leon<br />

Koopman, and Doris Rausch<br />

“Innovation is reflected in cost-effective solutions that customers<br />

can also relate to on an emotional level and appreciate for their<br />

function and economy. We are delighted that three products have<br />

been awarded two renowned prizes.” ■<br />

The TeleDentists Lead Educational Awareness Campaign on Dry Mouth<br />

Virtual dental service The TeleDentists<br />

is providing education to help increase<br />

the identification, diagnosis, and<br />

treatment of dry mouth, also known as<br />

xerostomia, beginning with the city of<br />

New York. The condition is a common<br />

oral condition among the elderly<br />

together with periodontal disease and<br />

dental caries, and can cause serious<br />

complications in the oral cavity.<br />

Dr. Maria Kunstadter<br />

To combat this silent epidemic, The<br />

TeleDentists has partnered with calcium phosphate rinse maker<br />

SalivaMAX to provide teledentistry and relief to xerostomia and other<br />

oral health conditions.<br />

“As dentists, we see the damaging effects of dry mouth every day. If<br />

you’re not aware that you have the condition, and don’t see a dentist<br />

before the damage sets in, you may end up needing extensive dental<br />

work,” said The TeleDentists Co-founder Dr. Maria Kunstadter. After<br />

a virtual consultation, a solution, such as a prescription rinse, can<br />

be found.<br />

A rinse for<br />

dry mouth<br />

The connected care platform does not take the place of the local<br />

dentist, but facilitates emergency care and coordinates the followup<br />

trip to the dentist. It can be especially helpful for those who lack<br />

access to a dentist. Teledentistry has also been tested as a means of<br />

pushing oral health video visits into underserved areas like low-income<br />

neighbourhoods and community health centres. ■<br />

Formlabs Partners with BEGO for 3D Printed Crowns and Bridges<br />

<strong>Dental</strong> customers of 3D printing system<br />

manufacturer, Formlabs, will soon be able<br />

to 3D print crowns and bridges for patients<br />

with BEGO’s best-in-class dental materials<br />

in a new partnership. The completely digital<br />

dental workflows will enable a rapid, low-cost,<br />

and iterative process for better patient care<br />

and case acceptance.<br />

“Directly printing temporary crowns and<br />

bridges are one of the most sought-after<br />

applications from Formlabs customers. By<br />

partnering with BEGO and leveraging their<br />

130 years of dental experience, we will be<br />

able to not only address this need, but take<br />

it a step further by offering materials for<br />

permanent crowns. We are excited to see<br />

how this partnership can continue to advance<br />

the dental industry and overcome the major<br />

challenges labs and dentists face as digital<br />

dentistry becomes a standard<br />

for patient care,” said Dávid<br />

Lakatos, chief product officer<br />

at Formlabs.<br />

chief executive officer of BEGO <strong>Dental</strong>, Axel<br />

Klarmeyer, said, “We could not be happier<br />

to partner with Formlabs, especially at this<br />

time, where digital dentistry is reaching a<br />

breakthrough. It took some time and a lot<br />

of effort and commitment of all involved<br />

people to be able to offer to the market a<br />

fully validated workflow for final restorations.<br />

This partnership underlines BEGO’s leading<br />

position in the dental 3D printing materials<br />

market.” ■<br />

3D-Printers for Labs of All Sizes<br />

Printers from German prototyping company<br />

Rapid Shape allow lab owners to make an<br />

impact in the dental prosthetic industry. Small<br />

labs can start 3D printing with professional<br />

equipment on a small budget, while dentists<br />

can print locally even without specialist<br />

knowledge. Besides its D20+ printer, which is<br />

the most economic professional 3D printing<br />

solution for dental labs, the company also<br />

manufactures D30+ and D40II, which are fast,<br />

flexible, and semi-automated, and D30+ ortho,<br />

which prints up to six models in 20 minutes.<br />

Rapid Shape has an open material system with a growing material library,<br />

and compatibility with common CAD programmes<br />

Rapid Shape products communicate with each other, simplifying complex processes<br />

A machine that works 24/7<br />

The key to printing large quantities efficiently<br />

is automation. For example, the D90+, which<br />

is meant for industrial dental production, has<br />

an automation system for up to eight selfloading<br />

platforms. The ready built job is taken<br />

out directly and the next print starts without<br />

any delay. This means that the machine is<br />

able to work without breaks, and even in<br />

night shifts. Another labour-saving feature<br />

can be seen in the automated part separation<br />

module (ASM, patent pending) for the D100+<br />

ortho. Multiple print jobs are collected in an<br />

integrated catch tank, eliminating the need<br />

for a human operator. It is also fast, and able<br />

to print up to 24 precise ortho models in 25<br />

minutes. ■<br />

Carestream <strong>Dental</strong> Introduces Digital<br />

Dentistry Difference Campaign<br />

With an educational campaign, digital dental solutions provider,<br />

Carestream <strong>Dental</strong>, will educate consumers about the benefits<br />

of digital dentistry, and arm doctors with resources to prompt<br />

conversation with their patients, solving a significant awareness<br />

gap.<br />

According to surveys, patients across the globe believe that the<br />

oral healthcare industry lags behind both optical and orthopaedic<br />

in terms of the technology used. Even more surprising, less than<br />

half of patients even believe their doctor uses very advanced<br />

technology.<br />

The campaign will explain how 3D CBCT imaging<br />

allows a more complete and detailed picture<br />

“It is a missed opportunity when you consider that doctors<br />

are investing in digital dentistry to improve patient care, yet<br />

many patients do not understand the level of advanced digital<br />

technology the industry offers, or how it can change their lives,”<br />

said Ed Shellard, D.M.D., chief dental officer of Carestream <strong>Dental</strong>.<br />

“This campaign will change that by speaking directly to consumers<br />

about why they should be asking about the technology used by<br />

their doctor.”<br />

This education is likely to help increase patient retention, bring in<br />

new patients, and enhance patient perception of care. The tools<br />

available include a video and infographics which can be shared<br />

through social channels, in a doctor’s waiting room, or referenced<br />

during patient consultations. ■<br />

The campaign will explain how a digital scan is<br />

more comfortable and quicker

Gain Practical Knowledge and Improve Treatment Success<br />

Dr. Peter Wöhrle, who will be a speaker<br />

and moderator at the upcoming Nobel<br />

Biocare Global Symposium <strong>2020</strong> in Las<br />

Vegas, US, gave insights into what implant<br />

professionals can expect at this world-class<br />

event.<br />

He said, “What I always find exciting about<br />

Nobel Biocare symposia are the first<br />

revelations of innovative new solutions that<br />

have real potential to improve the way we<br />

can treat patients, and subsequently make<br />

my practice stand out from the rest. This<br />

year is no exception.”<br />

In particular, he is heartened that the panel<br />

of speakers will include the next generation<br />

of experts, who have already excelled in<br />

implant dentistry and are bringing a new<br />

approach and perspective to the field.<br />

“On a personal level, it’s extremely<br />

rewarding to network with other dental<br />

Dr. Peter Wöhrle<br />

professionals. I learn so much from the<br />

experiences my colleagues are having,<br />

we compare the challenges we have<br />

to deal with, share different opinions<br />

about this exciting and rapidly evolving<br />

market. It can be challenging for a lot<br />

of practitioners and technicians to find<br />

the time to interact with their peers, but<br />

don’t underestimate how much you can<br />

learn from networking and socialising. I find<br />

this such a valuable part of the symposia<br />

Delivering predictable aesthetic outcomes,<br />

combined with shorter time-to-teeth, is<br />

paramount in today’s market place<br />

At the Global Symposium, you can gain<br />

practical knowledge to improve treatment<br />

success and skill sets with a mix of hands-on<br />

sessions, discussions and presentations from<br />

many experts<br />

experience,” he said.<br />

The programme will feature topics of interest<br />

such as hard and soft tissue regeneration,<br />

treatment planning, managing complications,<br />

extreme cases, ceramic implants, and digital<br />

dentistry. These solutions are based upon<br />

scientific principles, which are presented in a<br />

logical and convincing way. ■<br />

The panel of speakers is comprised of a<br />

diverse group of experts from different<br />

specialties, both from clinical practice and<br />

scientific research, many of whom have been<br />

world-renowned for many years<br />

The question of how dental implant professionals around the world can advance their skills and practice<br />

implant dentistry at the highest level is answered at the symposium<br />

Rebranding as a Premium <strong>Dental</strong> Tourism Destination<br />

The rise of India, Malaysia and Thailand<br />

as medical tourist destinations comes at<br />

the expense of Singapore, which is rapidly<br />

losing market share to its neighbours<br />

which are able to offer cheaper healthcare<br />

and compelling savings to tourists.<br />

In particular, many tourists are drawn by<br />

lower costs of dental work, which are done<br />

by local dentists who had returned from<br />

overseas studies. Some<br />

medical groups have<br />

already set up offices<br />

in regions such as<br />

Vietnam and China,<br />

to take advantage of<br />

the demand. Others<br />

have diversified<br />

their foreign<br />

patients<br />

base to lesstraditional<br />

markets<br />

such as Myanmar, Cambodia,<br />

Bangladesh, and India.<br />

According to Dr. Melvin Look<br />

of Pan<strong>Asia</strong> Surgery Group,<br />

to stay ahead, private<br />

groups here must continue<br />

to reinvent themselves and<br />

reinvest, and start looking<br />

into exporting Singapore<br />

medicine overseas, rather<br />

than wait for the patients<br />

to come.<br />

Others, such as Dr. Kelvin Loh of IHH<br />

Healthcare, believe that as healthcare<br />

standards in neighbouring countries move<br />

up the healthcare value chain, Singapore<br />

will stand out with its proven track record<br />

of delivering superior clinical outcomes.<br />

“Singapore can stay ahead of the curve by<br />

continuing to enhance its service offerings,<br />

such as investing in state-of-the-art<br />

Dr. Kelvin Loh<br />

facilities, disruptive medical technologies,<br />

and a strong team of doctors and healthcare<br />

professionals.”<br />

In the days to come, medical tourism to<br />

Singapore will be supported by regional<br />

growth trends, with the demand for quality<br />

private healthcare rising as populations<br />

age. ■<br />

Prescription of Opioids and Antibiotics for Emergency <strong>Dental</strong> Conditions<br />

A study in the <strong>March</strong> issue of The Journal of the American <strong>Dental</strong><br />

Association (ADA) from the Centres for Disease Control and<br />

Prevention found that antibiotics and opioids are frequently<br />

prescribed during emergency department visits for dental<br />

conditions, further emphasising the need for continued efforts to<br />

combat both opioid abuse and overuse of antibiotics.<br />

The authors found that more than 50% of patients who visited<br />

<strong>Dental</strong> Updates<br />

Infection and Prevention Control<br />

Recommendations for Healthcare<br />

Professionals in the Current Coronavirus<br />

Situation<br />

Based on currently available information about COVID-19,<br />

guidance has been provided by the Centers for Disease Control<br />

and Prevention. These include minimising chance for exposures,<br />

adherence to standard and transmission-based precautions,<br />

patient placement, taking precautions when performing aerosolgenerating<br />

procedures, collection of diagnostic respiratory<br />

specimens, and management of visitor access and movement<br />

within the facility.<br />

Personal protective equipment<br />

There is an increased emphasis on early identification and<br />

implementation of source control, meaning putting a face mask<br />

on patients presenting with symptoms of respiratory infection.<br />

Updated recommendations include reserving airborne infection<br />

isolation rooms for patients undergoing aerosol-generation<br />

procedures, while patients with known or suspected COVID-19<br />

should be cared for in a single-person room with the door closed.<br />

Based on local and regional situational analysis of personal<br />

protective equipment (PPE) supplies, facemasks are an acceptable<br />

alternative when the supply chain of respirators cannot meet the<br />

demand. Available respirators should be prioritised for procedures<br />

that are likely to generate respiratory aerosols, which would<br />

pose the highest exposure risk to healthcare personnel. As major<br />

distributors in the United States have reported shortages of PPE,<br />

specifically N95 respirators, alternatives such as elastomeric halfmask<br />

and full facepiece air purifying respirators, and powered air<br />

purifying respirators should be considered.<br />

Eye protection, gown, and gloves continue to be recommended. ■


An Online<br />

Journey to Healthcare and Wellness<br />

DoctorxDentist started off as<br />

a simple blog in 2016 where<br />

doctors and dentists could<br />

contribute educational articles<br />

and answer health-related<br />

enquires. Today, the platform<br />

is supported by 300 doctors<br />

from 33 different specialties.<br />

Tristan Hahner, Co-founder of<br />

DoctorxDentist, shares his vision<br />

for the platform and beyond.<br />

An alternate window<br />

Healthcare is very personal and private<br />

to each individual. Marrying this into the<br />

Internet space provides people a convenient<br />

alternative to better understand their health<br />

conditions and even exchange treatment<br />

experiences.<br />

The majority of these online sources specific<br />

to healthcare are written to be general to be<br />

relatable to the masses. While the availability<br />

of such articles are useful in many ways,<br />

they can easily allow people to assume the<br />

worst too, bringing forth cyberchondria, a<br />

term coined for an Internet-induced anxiety<br />

from self-diagnosing health problems<br />

online, said Tristan Hahner, Co-founder of<br />

DoctorxDentist (DxD).<br />

He explained, “In the past, for example,<br />

people considering a wisdom tooth<br />

extraction surgery would proceed with<br />

treatment along with a sense of assurance,<br />

after hearing from the surgeon about<br />

their prognosis. Today, however, the mere<br />

mention of a possible nerve damage during<br />

surgery could spook patients into changing<br />

their minds and even opting out of surgery.“<br />

Hahner stressed that patients ought to be<br />

thoroughly informed of all the risks and<br />

dangers of treatments before making a<br />

decision. In addition to the insights they<br />

are able to gain through researching their<br />

medical health online, he highlighted the<br />

key is to cross-check the online information<br />

with trained physicians and attend physical<br />

consultations as these opinions help to put<br />

things into perspective for patients, on a<br />

case-by-case basis.<br />

Turning to the Internet for diagnosis<br />

As early as 2002, about 93 million Internet<br />

users in the US are able to access health<br />

information from online sources, according<br />

to a study released by the Pew Internet &<br />

American Life Project. This statistic has<br />

definitely grown exponentially, Hahner<br />

said, as the world becomes more digitally<br />

connected and reliant on the web.<br />

He further pointed out that the platform has<br />

seen an upward trend in web traffic as more<br />

users in Singapore are researching their<br />

health problems online, and elaborated, “I<br />

notice an increased level of sophistication<br />

in users’ questions – a sign that users<br />

have aggregated knowledge about a given<br />

subject. One example is a recent question<br />

we have received on the dental effects<br />

of hydrogen peroxide in teeth whiteners<br />

where the user is clearly aware of potential<br />

negative side effects of hydrogen peroxide.”<br />

20 DENTAL ASIA MARCH / APRIL <strong>2020</strong>


<strong>Dental</strong> Management<br />

Explaining the reasons for users to seek<br />

health advice online, Hahner credited<br />

the option to be anonymous, especially<br />

when identity protection is key to users.<br />

And on costs of treatments, which is a<br />

popular concern among DxD users, the<br />

platform features articles with detailed<br />

cost breakdowns and are well-received.<br />

Particularly for the Singapore market, he<br />

pointed out that Singaporeans are open<br />

to receiving multiple opinions from various<br />

doctors, and are “very meticulous” and<br />

like to be well-informed and fully prepared<br />

before making a decision.<br />

The lack of information is a dangerous thing<br />

Information in the world of the Internet<br />

travel fast, and at times, unverified or even<br />

fake. Hahner acknowledged the danger of<br />

using information that is not verified by<br />

accredited and licensed entities, and said<br />

that “casual” health information found<br />

online may have been overly simplified,<br />

misinterpreted, taken out of context, and<br />

even rife with conflicts of interests at times.<br />

He explained, “Many content writers of such<br />

unaccredited sources have no background in<br />

medicine and rely on second- or even thirdhand<br />

sources. For example, teeth whitening<br />

products have been declared harmful by<br />

some online sources when dentists have<br />

clarified that the levels are often too low to<br />

damage otherwise healthy teeth. Relying on<br />

and trusting unverified health information<br />

have the potential to cause public health<br />

scares, monger irrational fear and even<br />

complicate proper treatment.”<br />

This brings forth an opportunity for DxD as<br />

a platform that brings health professionals<br />

together to share their knowledge and<br />

expertise. Having an online voice on a<br />

content platform multiplies the ability of<br />

doctors and dentists to help and effect<br />

change, from helping individuals to helping<br />

populations all around the world.<br />

“As with doctors, I stress that patients<br />

should always consult doctors to clarify<br />

any medical doubts and queries. Reading<br />

up health content is a great way to expand<br />

our health knowledge and stay informed<br />

of the latest news in the medical sphere.<br />

Nevertheless, always check with a doctor,<br />

who can then put such information into<br />

context and present patients with completed<br />

information,” Hahner said.<br />

“Health is very personal and individual<br />

– what applies to one may not apply to<br />

another; only a doctor, equipped with the<br />

necessary tests, observations, knowledge<br />

and experience can safely and reliably<br />

prescribe the best course of action.”<br />

More than an information provider<br />

DxD envisions a world where everyone –<br />

regardless of language or location – is<br />

empowered to make better informed health<br />

decisions. As the only website in Singapore<br />

certified by the Health On the Net Foundation<br />

(HON) for trustworthy medical information,<br />

DxD takes its responsibilities as information<br />

provider seriously.<br />

Other than supplying the public with<br />

accurate health information, DxD also<br />

aims to support medical practitioners in<br />

Singapore. “We help them to be recognised<br />

for the excellent work they do, and we keep<br />

their practises alive, even in difficult times<br />

like this, where patients are afraid to go<br />

to hospitals because of the coronavirus<br />

outbreak. Through the DxD platform,<br />

Singapore doctors are able to connect<br />

to the public in a safe and productive<br />

environment,” said Hahner.<br />

DoctorxDentist is now available also<br />

in Indonesia, where there are just 0.2<br />

physicians per 1,000 people according to<br />

the World Health Organisation. Launching<br />

a local team and website will bring expert<br />

health content to Indonesians, while growing<br />

Indonesian patient referrals to Singaporean<br />

doctor partners. Indonesian patients bring<br />

revenues of $100 million each year to<br />

Singaporean doctors, but many medical<br />

practises in Singapore lack an effective<br />

marketing channel to reach them.<br />

“However, I would also highlight that<br />

engaging in DxD’s services does not<br />

constitute as nor take the place of a<br />

medical consultation, and are, therefore,<br />

not considered telemedicine. It is our<br />

longstanding belief that it is best for patients<br />

to visit a doctor for their medical issues.” DA<br />

Word of Mouth<br />

WORD OF MOUTH<br />

By Dr. Kevin Ng<br />

Dr. Kevin Ng’s post-graduate qualifications include Master of <strong>Dental</strong> Surgery (Sydney), Fellowship of the Royal Australasian College of<br />

<strong>Dental</strong> Surgeons (FRACDS), Diploma in Implant Dentistry at the Royal College of Surgeons of England, and Membership of the Faculty of<br />

<strong>Dental</strong> Surgery (MFDS) at the Royal College of Surgeons of Edinburgh. He has been part-time lecturing on oral and maxillofacial surgery<br />

and cariology at Hong Kong University since 1981. Here, he shares the three dental instruments that have been most useful to<br />

him at a private practice in Hong Kong.<br />

CS 9600 CBCT Scanner from Carestream<br />

The high resolution of the CS 9600 CBCT system provides crisp images with exact<br />

anatomy landmarks that help tremendously in assessment and planning for all my dental<br />

surgeries. Its ability to capture images at low doses meets my safety considerations<br />

for patients.<br />

As all my 2D images, 3D images, and 3D face scans are assessable from the accompanying<br />

software, CS Imaging version 8, communicating with patients has become easier. Patients<br />

trust us more when we stay up-to-date with the latest technological advancements.<br />

CAD/CAM data assessable from the same software also makes liaising with technicians<br />

more convenient than before, when it comes to making surgical stents and temporary<br />

restorations for implant surgeries.<br />

iTero Element 5D from Align Technology<br />

Besides saving costs on traditional impression materials, I have found that digital<br />

impressions produced by intraoral scanner are more accurate and precise.<br />

I’m also able to detect inter-proximal caries early. Instead of sending physical<br />

impressions to the laboratory, I can now send the digital impressions via email,<br />

which is a big time-saver.<br />

When I can explain treatment outcomes using the scans, patients are able to<br />

understand me better. It also makes diagnosis and treatment planning better<br />

and more efficient, which will ultimately translate into the clinic’s bottom line.<br />

Waterlase iPlus all-tissue laser from Biolase<br />

I use the minimally invasive dental laser system primarily in<br />

periodontal treatments, both on natural teeth and those affected<br />

by implantitis. Compared to traditional tools such as needles,<br />

drills and scalpels, the laser is relatively pain-free for patients. Its<br />

ability to remove soft tissue with no bleeding and allow enamel<br />

etching without the use of acid are also plus points.<br />

I also prefer using this in the debridement and irrigation of<br />

root canals in endodontic treatments compared to traditional<br />

chemomechanical methods. Finally, it comes with a good record<br />

system that helps me monitor treatment progress and saves<br />

me time.<br />

integrated solutions in implantology take<br />

clinicians from data capturing, restorative<br />

and implant planning, guided surgery and<br />

intraoral scanning to implant selection,<br />

positioning, restoration design and<br />

manufacturing, to restorative solution.<br />

Our customers do not have to worry about<br />

interfaces or compatibility at any point in<br />

time – it simply works.<br />

When customers invest in Dentsply Sirona<br />

products, they are assured that their<br />

investment is for the long term. A great<br />

example would be our Orthophos imaging<br />

devices. A practice might be just getting<br />

started with digital dentistry, so we offer<br />

the flexibility of a hybrid 2D/3D unit that<br />

can be ordered with 2D capability, and<br />

to be upgraded to a 3D unit when the<br />

practitioner is ready.<br />

Another example is CEREC, which integrates<br />

scanning, design, milling, grinding and<br />

sintering through CEREC Primescan,<br />

CEREC Software, CEREC Primemill, and<br />

CEREC SpeedFire*. This allows users to<br />

produce impressive restorations with<br />

precise margins in a thoroughly thoughtout<br />

workflow, from a single source that<br />

is only available from Dentsply Sirona.<br />

These CAD/CAM solutions open up a world<br />

of possibilities for customers in digital<br />

dentistry. For example, the time required to<br />

fabricate a zirconia crown can be shortened<br />

to as little as five minutes.<br />

and dental education?<br />

I first joined the company as general manager of the dental<br />

business at Carestream Health in Australia in 2013. My role is to<br />

technology and change lives.<br />

30 DENTAL ASIA MARCH / APRIL <strong>2020</strong>


<strong>Dental</strong> Profile<br />

At the core of what we do at Carestream <strong>Dental</strong> is our customers<br />

– our products are designed by clinicians, for clinicians. We work<br />

closely with the dental practitioners throughout <strong>Asia</strong> to understand<br />

their needs and workflows, and guide how products are developed.<br />

Their feedback also steers the educational services that we provide,<br />

to help them achieve better diagnostic and clinical outcomes for<br />

their patients.<br />

In what ways has Carestream <strong>Dental</strong>’s work transformed<br />

from what was offered in the pre-digital era?<br />

Together with the pioneers of our company – Eastman Kodak,<br />

Trophy Radiologie, and PracticeWorks – we have brought many<br />

new technologies to dental practitioners, such as modern film,<br />

digital radiography sensors, and orthodontic practice management<br />

software. We are committed to innovation, investing heavily in<br />

research and development to stay ahead of the curve, deliver bestin-class<br />

solutions, and expand into new areas.<br />

Thirdly, scalability. The needs and requirements of each practice<br />

can vary significantly. CS 9600 can be configured with the optimal<br />

fields of view and scanning resolutions for a clinician’s current<br />

clinical and financial requirements. As these needs change, the CS<br />

9600 Fields of View can be expanded up to 16x17cm and modules<br />

such as Face Scanning, Cephalometric imaging, Prosthetic Driven<br />

Implant Planning (PDIP), CS Airway, CS Model, and CS Model+ can<br />

be integrated with CS 9600 to enhance diagnoses and treatment<br />

planning capabilities.<br />

Another product Carestream <strong>Dental</strong> is known for is its<br />

intraoral scanner CS 3700. What has the feedback been like<br />

from dentists who have tried it?<br />

The response since we launched the CS 3700 last year has<br />

been positive. It combines high performance, ergonomics and<br />

intelligence all into one scanner, and comes with a 20% faster<br />

scanning speed than before.<br />

Additionally, we are at the forefront of CBCT technology, panoramic<br />

and cephalometric imaging, and intraoral sensors. In fact, more<br />

than 200,000,000 dental images are captured each year with<br />

Carestream <strong>Dental</strong> imaging. We also work on integrating products<br />

seamlessly into practices’ workflows, and enhance interactions<br />

with patients.<br />

Carestream <strong>Dental</strong>’s CS 9600 5-in-1 CBCT Imaging System<br />

was awarded the 2019 Cellerant Best of Class Technology<br />

Winner. What makes it stand out from others?<br />

Firstly, innovation and precision. Digital dentistry is constantly<br />

changing, and we want to enable dental professionals with<br />

technology that allows them to innovate and lead within their<br />

particular fields. The CS 9600 is our fifth generation CBCT imaging<br />

platform. It features intelligent automation, first-time right imaging<br />

technology, and highly simplified workflows. It is also customisable,<br />

and can be configured to suit any dental specialty.<br />

Secondly, speed and accuracy. The SmartPad feature on the CS<br />

9600 ensures scans can be taken both quickly and precisely.<br />

Instead of using traditional laser beams, the CS 9600 uses a live<br />

camera positioning system to align patients. These cameras are<br />

assisted with in-built AI technology, which allows a swift and highly<br />

precise patient setup, while reducing the need for retakes.<br />

Users have also noticed the completely new interface design on<br />

the software that comes with the intraoral scanner, CS ScanFlow.<br />

It consists of a four-step process: Scan, Check, Export, and Adapt.<br />

From a single scan, the interface gives clinicians the freedom to<br />

navigate among different workflows. <strong>Dental</strong> professionals can<br />

enjoy faster dataset processing, vibrant HD 3D digital impressions,<br />

and all of the other advanced features they enjoyed with our past<br />

scanning acquisition software updates.<br />

How important is continuing education for dental<br />

professionals?<br />

Anterior Full Ceramic Crown After a<br />

Complicated Fracture of the Natural Tooth<br />

By Prof. Dr. Juergen Manhart & CDT Hubert Schenk<br />

In the maxillary anterior region, the<br />

integrity of the teeth is of great<br />

importance to many people. In<br />

the case of damage, restoring an<br />

attractive smile is a great need for<br />

patients. Depending on the defect size and<br />

its configuration, various clinically proven<br />

direct and indirect therapeutic options are<br />

available. For heavily damaged anterior<br />

teeth, all-ceramic crowns are a reliable<br />

and proven therapy option for restoring<br />

function and aesthetics.<br />

Lithium-disilicate glass ceramic<br />

The integrity of their anterior teeth is of<br />

paramount importance for most patients due<br />

to their prominent position. The impairment<br />

of teeth in the anterior aesthetic zone by<br />

carious defects, chipping or fractures, clear<br />

visible fillings, discolourations, anomalies<br />

in shape, alignment and position within the<br />

dental arch often results in considerable<br />

restrictions for the patients. Therefore,<br />

dentists should take into account all aspects<br />

of treatment, including a team of different<br />

specialists, in order to preserve or restore<br />

the natural dentition.<br />

Today, the range of therapies in modern<br />

dentistry offers a variety of methods<br />

to restore or optimise the function and<br />

aesthetics of the teeth in the anterior<br />

region. These include – depending on<br />

the initial situation and the degree of<br />

destruction of the individual teeth –<br />

polychromatic multilayer direct composite<br />

restorations, laboratory-made or industrially<br />

manufactured composite veneers, ceramic<br />

veneers, partial veneers (additional veneers),<br />

veneer crowns, full crowns (metal ceramics,<br />

all-ceramics) and orthodontic measures 1-3 .<br />

A majority of today’s patients asks for<br />

aesthetic restorations and metal-free<br />

alternatives to traditional prosthodontic<br />

approaches. All-ceramic restorations have<br />

gained popularity during the last 30 years<br />

for a number of reasons; especially their<br />

favourable optical properties, excellent<br />

and durable aesthetic appearance, wear<br />

resistance, colour stability, chemical<br />

inertness and durability, biocompatibility,<br />

and strengthening of the remaining<br />

tooth structure when they are adhesively<br />

bonded 4-17 .<br />

In the last three decades, many different<br />

all-ceramic systems were introduced to the<br />

dental profession 19 . <strong>Dental</strong> ceramics can<br />

be classified according to their material<br />

composition, fabrication workflow (for<br />

example, powder-liquid slurry, slip-casting,<br />

pressable ceramics, CAD/CAM millable), or<br />

clinical indications 20-22 . Nowadays, the most<br />

common clinical indications for all-ceramic<br />

restorations consist of inlays, onlays, partial<br />

crowns, full crowns, bridges, veneers,<br />

posterior occlusal veneers (table tops/<br />

posterior cuspal protection restorations),<br />

implant abutments and implants 23-36 . These<br />

restorations present a scientifically proven,<br />

high-quality permanent treatment option<br />

for the aesthetically challenging anterior<br />

and load-bearing posterior regions when<br />

the indications and limitations of the<br />

respective ceramic systems are respected<br />

and an appropriate luting procedure<br />

is employed; their reliability has been<br />

documented in literature 18, 32, 37-56 . All-ceramic<br />

restorations are used meanwhile on a<br />

routine basis in everyday dentistry.<br />

For single-unit restorations, lithium-disilicate<br />

(LS2) glass ceramic is the material of choice for<br />

many dental practitioners because of its good<br />

mechanical strength (IPS e.max Press: 470<br />

MPa mean biaxial flexural strength), excellent<br />

aesthetic properties and its versatility. It can<br />

be used in monolithic form, when maximum<br />

strength is required (for example, tabletop<br />

restorations for increasing the vertical<br />

dimension of occlusion or posterior crowns),<br />

or in a layered form (pressed LS2 coping<br />

with additional veneering porcelain) when<br />

aesthetics is of utmost importance. Singleunit<br />

LS2-crowns demonstrate an excellent<br />

longevity for anterior 57-59 and posterior<br />

teeth 56-59 , comparable to the survival rate of<br />

metal-ceramic crowns 60, 61 .<br />

This clinical report illustrates the restoration<br />

of a maxillary central incisor affected by a<br />

complicated crown fracture with a veneered<br />

lithium-disilicate glass ceramic crown after<br />

endodontic therapy.<br />

Clinical case report<br />

Initial situation<br />

A systemically healthy 24-year old female<br />

patient presented in our dental clinic with<br />

a trauma-related fractured right maxillary<br />

central incisor. The accident had already<br />

occurred one week earlier abroad, where the<br />

patient, a medical student, was in a clinical<br />

traineeship. After the initial treatment of<br />

soft tissue injuries on the spot by a fellow<br />

student (Fig. 1a and b), the patient decided<br />

to cancel the stay abroad, where medical<br />

and dental facilities were lacking.<br />

During the examination in our clinic<br />

one week after the incident, the patient<br />

presented a still untreated traumainjured<br />

tooth 11 (Fig. 2a – b). The clinical<br />

inspection showed a complicated crown<br />

fracture with exposure of the pulp (Fig. 3);<br />

the incisal half of the clinical crown had been<br />

completely lost 62, 63 . Patient assessment<br />

revealed a sharp painful response to cold<br />

thermal stimulus using refrigerant spray<br />

and a pathologic response to percussion of<br />

the respective tooth 64 . Given that the pulp<br />

had already been exposed to the oral cavity<br />

environment for one week, the tooth showed<br />

unprovoked pain symptoms and root growth<br />

was completed. Together with the informed<br />

patient, we decided to completely remove<br />

the infected pulp with subsequent root canal<br />

treatment (Fig. 4a – c).<br />

The patient was informed about various<br />

therapeutic approaches (direct composite<br />

restoration, ceramic veneer, full ceramic<br />

crown, PFM crown) including their<br />

respective advantages and disadvantages,<br />

and associated costs. The patient decided<br />

in favour of an adhesively luted glass<br />

ceramic crown made of veneered lithiumdisilicate<br />

ceramics. This restoration type<br />

can be recommended as evidence-based<br />

treatment in the anterior region 65 . In<br />

literature, survival rates of between 93.8%<br />

and 96.8% are reported at five-, eight-, or<br />

10-year observation periods 57-59 .<br />

Clinical Feature<br />

In principle, in the dental aesthetic analysis<br />

by the ceramist technician already a<br />

“virtual layering” of the restoration is<br />

done, with determination of the necessary<br />

ceramic masses. The result of this “virtual<br />

layering” is recorded in the ceramic buildup<br />

scheme (Fig. 8). This procedure is done on<br />

site in the dental laboratory under ideal<br />

lighting conditions (which are often not<br />

found in dental practices) by the ceramist<br />

technician, who will ultimately also fabricate<br />

the restorations.<br />

Fig. 7a – d: Aesthetic analysis by the dental technician. The distribution of the different shades and<br />

translucent or opaque tooth areas in the area to be restored are determined<br />

Fig. 8: Ceramic layering concept as result of<br />

tissue situation had completely healed.<br />

After a waiting period of three months, a<br />

new clinical examination was carried out,<br />

in which tooth 11 and its adjacent teeth,<br />

including the antagonists in the lower jaw,<br />

were inconspicuous (Fig. 6). The patient<br />

was asked to present herself the next day<br />

for shade determination and, in general,<br />

for dental aesthetic analysis in the dental<br />

laboratory 66 . A basic requirement for<br />

accurate colour determination is that the<br />

teeth are not dehydrated, otherwise they<br />

appear lighter and more opaque 67-69 .<br />

Aesthetic Analysis<br />

As part of the aesthetic analysis by the<br />

dental technician, the distribution of the<br />

different shades of colour and translucent<br />

or opaque tooth areas in the area to be<br />

restored is determined (Fig. 7a – d). The ageappropriate<br />

design of the restoration with<br />

corresponding individual characteristics -<br />

enamel cracks, white spots, mamelons, halo<br />

effect - as well as the appropriate surface<br />

texture, and the correct gloss level, are also<br />

analysed.<br />

If the colour analysis is performed directly<br />

by the dental technician, and not by the<br />

dentist or other practice staff, there is<br />

usually no misunderstanding and the<br />

responsibilities for this important aspect in<br />

the treatment process are clearly assigned.<br />

Such a procedure eliminates the risk of<br />

communication breakdowns and saves<br />

time. It is through direct contact with the<br />

patient that the dental technician is able to<br />

produce an aesthetically perfect matching<br />

ceramic crown 70 . It is optimal if this analysis<br />

is performed before treatment starts. This<br />

allows the dental technician to form his<br />

own impression of the initial situation,<br />

and also to query, unfiltered, the patient’s<br />

expectations of the new restorations. A<br />

patient-specific optimal tooth position<br />

and shape of the restorations is sought 71 .<br />

Implementation of the individual functional<br />

and aesthetic optimum for each patient<br />

thus requires close collaboration with<br />

the specialised dental technician from<br />

the beginning of the planning phase. The<br />

independent aesthetic analysis of the<br />

intraoral situation by the ceramist is a<br />

basic requirement for success 72 .<br />

Clinical Feature<br />

Tooth preparation<br />

In the next appointment, the tooth 11<br />

was prepared for receiving a full ceramic<br />

crown with a circumferential shoulder with<br />

rounded inner edges (Fig. 9a – c).<br />

The strength of all-ceramic restorations<br />

is determined by the type of ceramic used<br />

with the resulting inherent mechanical<br />

stability of the respective ceramic<br />

material. Furthermore, the fracture<br />

strength is determined by the geometry<br />

of the restoration and, thus, by the shape<br />

of the cavity or crown preparation. The<br />

basic principle of preparation design for<br />

all-ceramic restorations avoids tensile<br />

stresses in the material as much as<br />

possible and loads the restoration primarily<br />

in compression mode by an adequate<br />

preparation geometry 73, 74 . Fracture strength<br />

of the restorations is determined by size,<br />

volume, shape and surface characteristics<br />

of the ceramic material, and additionally<br />

by structural inhomogeneities introduced<br />

during the manufacturing process 75 .<br />

The dentist must be aware of the fact<br />

that the shape and finish of the tooth<br />

preparation have a major impact on the<br />

clinical success and longevity of all-ceramic<br />

restorations 76-78 . The preparation should<br />

exhibit a retention form and resistance<br />

form optimal for a ceramic crown 76, 79, 80 :<br />

• height of prepared tooth (abutment<br />

height) minimum 4mm<br />

• occlusal convergence angle between 6<br />

and 10 degrees<br />

• finish line: circumferential shoulder<br />

with rounded inner edges or obvious<br />

deep chamfer with 1mm width<br />

• incisal / occlusal reduction of 1.5 – 2.0mm<br />

(adhesively luted full contour lithiumdisilicate<br />

crown: minimum 1.0 mm)<br />

• axial reduction depth (sufficient circular<br />

crown thickness) of 1.2 – 1.5mm<br />

• in the anterior region: a rounded incisal<br />

edge<br />

• rounded internal line angles and point<br />

angles<br />

• smooth surface texture<br />

Tooth substance removal was controlled<br />

in all dimensions. Attention was paid to<br />

the possibility of a sufficient palatinal<br />

layer thickness of the crown framework to<br />

be produced, even in positions which the<br />

tooth occupies, in addition to the static<br />

occlusion, in dynamic occlusion (Fig. 10).<br />

After tooth preparation<br />

During the fabrication of highly aesthetic<br />

restorations, the influence of the shade of<br />

the prepared tooth on the final result is a<br />

decisive aspect. After finishing the crown<br />

preparation, the shade of the prepared<br />

tooth substance was documented by the<br />

dentist with a digital photo referencing<br />

to a special shade guide (IPS Natural Die<br />

Material shade guide, Vivadent, Schaan,<br />

Liechtenstein). The image file was then<br />

made available electronically to the dental<br />

laboratory. This enables the technician,<br />

who otherwise has no information about<br />

the colour of the tooth stump, to fabricate a<br />

model die similar in colour to the prepared<br />

tooth of the patient. This forms the basis<br />

from which the correct shade, translucency<br />

and brightness values of the all-ceramic<br />

restoration will be selected.<br />

In order to achieve a perfect impression, the<br />

marginal gingiva was displaced by insertion<br />

of a retraction cord to the sulcus (Fig. 11a –<br />

b). After taking impressions of the prepared<br />

tooth and the antagonistic dentition, an<br />

occlusion protocol with Shimstock foil was<br />

made, as well as intermaxillary registration<br />

by fabricating an interocclusal record in<br />

maximal intercuspal position and arbitrary<br />

transfer of the maxillary position using a<br />

facebow record were performed 81, 82 .<br />

A diagnostic template made from a gypsum<br />

duplicate of the analytical wax-up using<br />

a transparent polyethylene foil allows the<br />

chairside fabrication of a direct provisional<br />

restoration with correct dimensions and<br />

alignment (Fig. 12a). The provisional was<br />

seated using a eugenol-free temporary<br />

cement (Fig. 12b).<br />

Laboratory work<br />

In the dental laboratory, the ceramic<br />

crown for tooth 11 was produced. For<br />

this purpose, a crown framework made of<br />

lithium-disilicate reinforced high-strength<br />

glass ceramic was pressed corresponding<br />

to the anatomically correct shape of the<br />

respective tooth (Fig. 13a). This coping<br />

was subsequently finalised by individual<br />

veneering with layered porcelain (presslayer-technique)<br />

(Fig. 13b – g).<br />

Try-in and adhesive luting procedure<br />

One week after impressioning, the final<br />

appointment was scheduled. After the<br />

removal of the provisional restoration and<br />

cleaning of the tooth with a rotating brush<br />

and fluoride-free prophylaxis paste, the<br />

gingiva presented in healthy condition (Fig.<br />

pastes, the aesthetics of the ceramic<br />

crown was checked intraorally with<br />

reference to hydrated adjacent teeth and<br />

the correct shade of the luting resin was<br />

determined 83-85 . Subsequently, the precise<br />

Fig. 15: Placing a retraction cord to expose the<br />

fit of the crown on the prepared tooth and<br />

quality of proximal contacts were checked<br />

before minor functional interferences<br />

during protrusive and laterotrusive<br />

movement paths were eliminated.<br />

The method of cementation of the crown to<br />

the prepared tooth was by adhesive luting,<br />

as opposed to conventional cementation.<br />

This gives a positive effect on the overall<br />

strength of the restoration, in particular for<br />

glass ceramic materials, which are more<br />

prone to bulk fracture and chipping effects<br />

than zirconia. Ceramic materials with<br />

fracture strength less than 350 MPa are not<br />

indicated for conventional cementation 36 .<br />

Among those are feldspathic porcelains<br />

and leucite-reinforced glass ceramics that<br />

have to be placed adhesively using bonding<br />

agents and luting resins. Due to the adhesive<br />

bond between the ceramic restoration and<br />

enamel or dentin, a considerable increase<br />

in strength can be obtained because the<br />

inner surface of the ceramic restoration<br />

no longer acts as a mechanical boundary<br />

line at which fracture-causing cracks can<br />

initiate due to tensile stresses 86 .<br />

The adhesive cementation of ceramic<br />

restorations is a very technique-sensitive<br />

procedure. In order to achieve a reliable and<br />

long-lasting bond to the tooth structures, it<br />

is of utmost importance to prepare this step<br />

carefully and to observe the cementation<br />

protocol 87 . Prior to the luting procedure, the<br />

marginal gingiva was displaced to expose<br />

the complete shoulder using a retraction<br />

cord (Fig. 15). Afterwards, the inner surfaces<br />

of the lithium-disilicate glass ceramic crown<br />

were etched with hydrofluoric acid for 20s<br />

(Fig. 16). After thoroughly rinsing and drying<br />

the crown, the fitting surfaces were silanised<br />

(Fig. 17) 88-91 . After adhesive pretreatment of<br />

the prepared tooth by conditioning enamel<br />

intaglio surfaces and the prepared tooth<br />

both with dual-curing resin cement in<br />

the previously determined shade and the<br />

restoration was positioned on the tooth with<br />

light finger pressure (Fig. 20a – d).<br />

Two weeks after placement, the restoration<br />

exhibited an optimal functional and aesthetic<br />

integration into the neighbouring teeth<br />

(Fig. 21a – b). Background illumination<br />

demonstrates the excellent light<br />

transmittance capacity of the glass<br />

ceramic crown, which impresses by having<br />

virtually the same optical properties<br />

as the surrounding natural dentition<br />

(Fig. 22). Ultraviolet light activates the<br />

inherent fluorescence properties of the<br />

restoration, which are equal to natural<br />

tooth structure (Fig. 23). Silicate ceramics<br />

exhibit translucency effects and lightoptical<br />

properties that are comparable<br />

to natural hard tooth substance, making<br />

them ideal for fabricating restorations<br />

that have to meet highest aesthetic<br />

demands. The light scattering of silicate<br />

ceramics also supports a natural vital<br />

appearance of the adjacent gingiva.<br />

The difference to this “pink aesthetics”<br />

becomes clear in comparison with metalsupported<br />

restorations, which block this<br />

light conduction towards the marginal soft<br />

tissue and often cause a greyish shading<br />

on the marginal gingiva 92, 93 . At the end<br />

of the successful treatment, the patient’s<br />

smile was no longer compromised. The<br />

crown harmonises in dialogue with the lips<br />

(Fig. 24).<br />

Five years after adhesive cementation of<br />

the ceramic crown, there is still an excellent<br />

integration in the surrounding teeth, both<br />

in habitual intercuspation and in dynamics<br />

(Fig. 25a – e). The patient was still fully<br />

satisfied with the result and thanked the<br />

treatment team with a happy smile (Fig. 26).<br />

Conclusion<br />

All-ceramic restorations have achieved<br />

an excellent quality and are an<br />

indispensable therapeutic means for<br />

modern conservative and prosthetic<br />

dental treatment procedures 94 . Aesthetics<br />

and biocompatibility characterise these<br />

Clinical Feature<br />

Amlodipine<br />

Induced Gingival<br />

Enlargement<br />

By Dr. Anand Narvekar and Dr. Richa Kapoor<br />

Patients medicated with certain<br />

drugs may suffer from Drug<br />

Induced Gingival Enlargement<br />

(DIGO), which may interfere<br />

with aesthetics, mastication, or<br />

speech. Besides affecting one’s appearance,<br />

such gingival overgrowth also often impairs<br />

nutrition and oral hygiene, resulting in an<br />

increased susceptibility to oral infection,<br />

caries and periodontal diseases.<br />

Drugs associated with gingival overgrowth<br />

can be broadly divided into three categories:<br />

Anticonvulsants, calcium channel blockers,<br />

and immunosuppressants. Amlodipine<br />

is a dihydropyridine calcium channel<br />

blocker that is used in the management<br />

of both hypertension and angina. Ellis et<br />

al., first reported gingival sequestration of<br />

Clinical examination showed a generalised<br />

overgrowth of marginal and papillary gingiva<br />

throughout the maxilla and mandible in<br />

buccal, palatal, and lingual segment, with<br />

those on the mandibular anterior segments<br />

being more pronounced.<br />

The enlargement was firm in consistency,<br />

with slight bleeding on probing in mandibular<br />

anterior segment (Fig. 1 - 3). Periodontal<br />

pockets with a mean probing depth of 7mm<br />

were present in the posterior segments. (Fig.<br />

2 - 3). In maxillary and mandibular anterior<br />

segment, only pseudo pockets were present<br />

(Fig. 4 - 5). Palatal aspect of maxillary arch<br />

showed bead-like enlargement of marginal<br />

and papillary gingiva (Fig. 6). Marked<br />

enlargement was seen on buccal and lingual<br />

area of the mandibular arch. (Fig 7).<br />

Treatment<br />

Phase I – Scaling and root planing, followed by<br />

oral hygiene instructions, and chlorhexidine<br />

mouthwash. Drug modification.<br />

Phase II – Gingivectomy and gingivoplasty<br />

in maxillary and mandibular anterior region.<br />

Modified Widman Flap in posterior segments.<br />

Phase III – Maintenance phase<br />

After scaling and root planing, there was<br />

marked reduction in the inflammation and<br />

the tissues became firm in consistency<br />

(Fig. 8).<br />

Gingivectomy and gingivoplasty was done<br />

under local anaesthesia with a No. 15<br />

blade. Haemorrhage was controlled with<br />

pressure pack and non-eugenol periodontal<br />

dressing was given. Suitable analgesics with<br />

chlorhexidine mouthwash were advised.<br />

Postoperative healing after one week<br />

showed absence of enlargement, mild edema<br />

was visible but patient was asymptomatic.<br />

Modified Widman Flap was done in remaining<br />

posterior segments. Internal bevel incision<br />

was made 0.5 – 1mm away from marginal<br />

gingiva, followed by sulcular incision. Full<br />

thickness mucoperiosteal flap was raised.<br />

After debridement, most areas had horizontal<br />

bone loss, except in 16 and 17 regions, where<br />

a hemiseptal defect was present. Osteoplasty<br />

was done to remove the bony ledge in the<br />

same region for better flap adaptation. Figure<br />

of eight sutures were given. (Fig. 8 – 10).<br />

One week post operatively, all sutures were<br />

removed (Fig. 12). Mandibular and maxillary<br />

anterior segment showed uneventful healing<br />

(Fig. 13 – 14).<br />

The treatment options for drug-induced<br />

gingival enlargement should be based<br />

on the medication being used, and the<br />

clinical presentation of the individual<br />

case. Consideration should be given to the<br />

possibility of substituting the drug.<br />

Besides surgical excision, maintenance<br />

carried out in the post-operative phase<br />

is crucial for preventing recurrence. The<br />

patient should be taught correct oral<br />

hygiene maintenance. Regular follow-ups<br />

are also needful. DA<br />

Simplified using<br />

a Novel, Huebased<br />

Direct<br />

Composite<br />

Resin System<br />

By Dr. Clarence Tam<br />

Rationale for Choice of Material<br />

The pursuit of natural restorations has been the mainstay of<br />

aesthetic dentistry for at least the last decade. It is known that<br />

the colour corollary of composite shades between manufacturers<br />

varies drastically, as well as with the reference Vita Classic shade<br />

guide 1 . To further complicate matters, the opacities and colour<br />

saturation of respective enamel and dentin shades also varies<br />

between systems, creating the need to generate a site-specific<br />

colour map of the tooth in a pre-dehydrated state. Enamel is an<br />

achromatic, inorganic dominant material. The hue or true colour<br />

of the tooth comes from the dentin. Value (brightness) and chroma<br />

(saturation) are modulated in nature according to the thickness<br />

of the enamel 2 . StyleItaliano is the first comprehensive anterior<br />

composite layering system to utilise a single, universal enamel shade,<br />

the thickness of which is designed to be modulated to generate<br />

greater or less chroma with a particular hue of dentin. To simplify<br />

matters, dentin options are distributed only between five options<br />

which vary significantly in colour space, making selection efficient:<br />

Si0, Si0.5, Si1, Si2 and Si3. Effect shades consist of MP (Multiplo),<br />

which is a translucent flowable with opalescent properties as well<br />

as M (Masque or Masking), which is a flowable featuring greater<br />

opacity that blocks out “shine through” in augmentation or fracture<br />

repair cases. Posterior restorations are simplified via the use of a<br />

single posterior shade (P), which has a beautiful chameleon effect<br />

and ideal sculptability.<br />

Enamel-Dentin Tooth Fracture<br />

An 11-year-old male, exhibiting an uncomplicated enamel-dentin<br />

fracture of tooth 21 (#9) MIBP, was presented to the practice.<br />

He had been opening a farm gate while duck shooting and the<br />

latch had sprung up, impacting his tooth. He had no immediate<br />

or delayed sensitivity, and the tooth remained vital. He was not<br />

interested in pre-prosthetic tooth whitening but was interested in<br />

exactly recreating the subtle optical nuances of the area that was<br />

fractured. Medical history was positive for controlled ADHD, with<br />

known drug allergies to cotrimoxazole, Ceclor and Amoxicillin. At<br />

the initial consultation, the tooth was smoothed, and 2% CHX (aq)<br />

was applied. Dentin conditioner and a glass ionomer provisional<br />

restoration were then placed to insulate the dentin (Fuji BULK, GC<br />

America). Possible optical and pulpal sequelae were discussed and<br />

full informed consent given.<br />

Procedure<br />

It is well known that the optical properties of enamel drastically<br />

change in a dehydrated state. The refractive index of water is 1.33<br />

and that of air is 1.00. Therefore, as the enamel interprismatic spaces<br />

lose water and gain air, they assume a lower refractive index, and gain<br />

a higher reflective index, essentially becoming more opaque. Shade<br />

selection was completed prior to application of topical anaesthetic,<br />

as the extended time of lip retraction (typically two minutes) could<br />

possibly affect the full state of hydration and thus incorrect colour<br />

selection. Shades selected were: dentin (Si2), enamel (E), masking<br />

(M) and Multiplo (MP). Marked horizontal perikymata-like maverick<br />

effects were noted and white tint was also planned to mimic the<br />

hypocalcified streaks of the natural optics in the adjacent tooth<br />

structure. The patient was anesthetised using one carpule of a 4%<br />

Articaine solution with 1:100,000 epinephrine. A split dam rubber<br />

dam format was utilised for isolation before conservatively rounding<br />

the fracture margins, blending the preparation to infinity before<br />

utilising micro air abrasion (27 micron aluminum oxide). A total<br />

etch technique was utilised before bonding using G-Premio Bond<br />

(GC America). The lingual shelf was created freehand using a precrimped<br />

Mylar strip and the E (Enamel) shade. The proximal axial<br />

and incisal halo were accentuated by rolling a thin worm of Si2 and<br />

placing it along the incisal and mesiolateral borders of the tooth with<br />

the strip still in place. To maximise the ability to block out the shinethrough<br />

of the oral cavity through the new restoration, a masking<br />

liner (M) was utilised in multiple thin layers prior to placement of the<br />

dentin volume proper using Si2. Incisally, the dentin lobules were<br />

sculpted and cured. It is critical to always judge each respective layer<br />

from the incisal view prior to curing to ensure that it has not been<br />

overbuilt, and that the volume is accurate. A translucent, opalescent<br />

flowable was applied to the negative space created between the<br />

dentin lobules and cured. A white tint was utilised and streaked in a<br />

similar horizontal pattern using the pre-operative colour reference<br />

photograph as inspiration. Finally, the enamel layer was completed<br />

in a single increment to minimise the risk of join lines from incomplete<br />

blending. Primary anatomy was developed using Sof-Lex discs<br />

(Sof-Lex, 3M). Secondary anatomy was created using a series of<br />

fine diamond burs. Tertiary anatomy refers typically to texture. Fine<br />

horizontal texture was created to mimic that seen in the contralateral<br />

tooth using a coarse green-stripe diamond bur running lightly across<br />

All in all, the patient received a restoration that was<br />

able to mimic the natural halo effect and translucency<br />

seen in the incisal window, married with hypocalcified<br />

tinting and a surface texture that allowed the restored<br />

tooth to aesthetically-integrate harmoniously into the<br />

dental arch once again. The patient was thrilled with<br />

the result and cannot wait to fracture another tooth so<br />

we can do this all over again. Just kidding. DA<br />

Considering Alternative<br />

Options for Teeth Lightening<br />

By Dr. Aodhan Docherty<br />

The appearance of our patient’s teeth is becoming ever more<br />

important to them and we know from a multitude of clinical studies<br />

that people make judgements about others from the appearance of<br />

their teeth. One of the major factors which influences this is the shade<br />

of the teeth. The perception of shade of the teeth is the result of the<br />

amount and wavelength of light that is reflected back to the eye. Here,<br />

we discuss a minimally invasive technique to improve the appearance<br />

of the smile and enhance self-confidence for our patients.<br />

Why teeth darken<br />

Shade is produced by a combination of the natural baseline colour<br />

of teeth which mainly comes from the colour of the dentine, plus<br />

staining. The baseline colour of teeth is the result of how light<br />

interacts with the inherent structure of the tooth substrates. Stains<br />

are organic pigments which can be located either on the surface of<br />

the tooth within the biofilm layer (extrinsically) or within the tooth<br />

structure (intrinsically) 1 .<br />

Extrinsic stains are derived from smoking, dietary intake of tanninrich<br />

drinks and foods (for example, coffee, tea, and red wine), cationic<br />

antiseptics such as chlorhexidine, and metallic salts such as iron.<br />

Intrinsic stains are usually located within the dentine and are often<br />

from systemic or pulpal origin, such as tetracycline, fluorosis, pulpal<br />

haemorrhage products, molar incisal hypoplasia, amelogenesis<br />

imperfecta, dentinogenesis imperfecta, internal resorption, and<br />

ageing.<br />

At a molecular level these pigment molecules have multiple<br />

conjugated bonds which reflect light within the visible spectrum and<br />

this is the shade (hue and value) which we can see, which are called<br />

chromophores 2 . The larger the pigment the more chromophores<br />

they have, and therefore the darker they appear. With time, these<br />

extrinsic pigments join together and the larger they become the<br />

darker they are perceived 3 . Furthermore, the extrinsic pigments tend<br />

to penetrate the tooth structure with time and form a tightly woven<br />

network or matrix 3 . This creates a complex network of pigments<br />

which have large numbers of chromophores and hence appear dark.<br />

There are many options available for lightening the shade of teeth<br />

including scaling and polishing, teeth whitening or bleaching,<br />

composite resin veneers, porcelain veneers, crowns, micro-abrasion<br />

and air powdered polishing.<br />

Figs. 1-3: Before<br />

A minimally invasive solution<br />

The following case demonstrates the use of teeth whitening using<br />

opalescence 10% carbamide peroxide (Ultradent Products, USA).<br />

The patient is a male in his early twenties who originally presented<br />

asking to have porcelain veneers. After lengthy discussion, it was<br />

established that the features of his teeth which he did not like<br />

were primarily the shade and minor chipping. As an alternative to<br />

teeth whitening, followed by reshaping<br />

of the chipped edges was<br />

proposed. This leaves the option<br />

of embarking upon some minor<br />

orthodontics and composite resin<br />

bonding if deemed appropriate at<br />

re-assessment.<br />

The patient used the gel nightly for approximately eight hours for<br />

four consecutive weeks with minimal sensitivity or side effects. The<br />

anterior chipping was re-contoured at review.<br />

Simple, cost-effective, and non-invasive<br />

An acceptable result was achieved with combination of minor reshaping<br />

of the chipped edges. The patient did not have to undergo<br />

aggressive tooth preparations for porcelain veneers or have any<br />

restorative material added to his teeth to achieve a satisfactory<br />

outcome. We have minimised the restorative burden for this patient<br />

whilst still leaving the door open to allow him to embark upon any<br />

further dental cosmetic treatment in the future.<br />

This case epitomises the minimally invasive paradigm shift which is<br />

rapidly taking over the dental world. It demonstrates that simple,<br />

cost-effective and non-invasive treatment modalities can have a<br />

tangible effect upon the lives of our patients. DA<br />

Onlay for Upper Right Molar Using Chairside<br />

Workflow with 3Shape TRIOS Design Studio<br />

By Dr. Douglas G Watt<br />

A<br />

female patient, age 63, came<br />

to the practice requesting an<br />

orthodontic treatment and<br />

restoration for her dentition,<br />

which had had multiple failing<br />

posterior restorations. The case focused<br />

on her upper right first molar, which had a<br />

large amalgam restoration with secondary<br />

caries present. The patient requested<br />

a more aesthetic restoration to replace<br />

this and understood the need for cuspal<br />

coverage to protect the remaining tooth<br />

tissue.<br />

in-house manufacture of the restoration.<br />

The upper right first molar responded<br />

positively to the vitality test, and there was<br />

no sign of apical pathology on radiographic<br />

examination (Fig. 1i – ii).<br />

Fig. 3<br />

Treatment plan<br />

For the treatment, to prepare the tooth and<br />

to minimise the amount of tooth surface<br />

removed, a lithium disilicate onlay was<br />

used. This was carried out using a full<br />

digital workflow with direct integration<br />

between the 3Shape TRIOS Design Studio<br />

and the DGShape DWX-42W mill to allow for<br />

How 3Shape TRIOS Design Studio works<br />

The case was set up in TRIOS Design Studio<br />

as an inlay/onlay indication (Fig. 2i – ii).<br />

Following the software’s guided workflow,<br />

the margin line and insertion direction were<br />

defined and adjusted as necessary (Fig. 3).<br />

as required. The preferred level of contact<br />

between the teeth was chosen, and the<br />

set minimal thickness was in line with the<br />

manufacturer’s recommendations (Fig. 6).<br />

To assess dynamic occlusion, the software<br />

ran its virtual articulator. The design was<br />

corrected for occlusal interproximity and<br />

morphology by removing any working side<br />

and non-working side interferences (Fig.<br />

Achieving results<br />

Once design stages were completed, the<br />

crown was nested in preparation for milling<br />

and the block loaded into the DGShape<br />

DWX-42W in the correct position (Fig. 8i<br />

– 9). Following the milling, the restoration<br />

was cut off the reduced sprue, and the<br />

remaining sprue was smoothed. The<br />

Fig. 8ii<br />

Fig. 10ii<br />

restoration was then glazed, stained, and<br />

fired on a 15-minute firing cycle, before it<br />

was left to cool.<br />

Fig. 6<br />

Fig. 7i<br />

To confirm the fit, the restoration was tried<br />

in the mouth (Fig. 10i – ii). The fit surface<br />

of the restoration was then prepared with<br />

Ivoclar Vivadent Monobond Etch and<br />

Prime. After isolating the tooth with rubber<br />

dam, the tooth surface was prepared<br />

through sandblasting with 29-micron<br />

aluminium oxide, and acid etching with<br />

37% phosphoric acid etchant gel (Fig. 11i<br />

– ii). The prepared restoration was then<br />

bonded to the tooth using 3M Scotchbond<br />

universal, applied twice. Air thinned and left<br />

uncured, the fit surface of the restoration<br />

was loaded with 3M Rely-x Unicem.<br />

Fig. 7ii Fig. 9<br />

After the restoration was seated, it was<br />

flash cured. Any excess was removed,<br />

and the contacts were flossed prior to full<br />

curing. A final cure of the margins was<br />

carried out for 60 seconds on all accessible<br />

margins, with a glycerine gel covering to<br />

eliminate the oxygen inhibition layer (Fig.<br />

the design took 10 – 15 minutes, and the<br />

Glazing and firing took 20 minutes with<br />

The use of 3Shape TRIOS scanner and<br />

TRIOS Design Studio software as part of<br />

the continuous and seamless workflow,<br />

along with the direct integration with<br />

for in-house manufacture, and same day<br />

of TRIOS Patient Specific Motion made<br />

this case even more predictable, as the<br />

patient’s actual excursive and protrusive<br />

Behind the Scenes<br />

As an apprentice dental technician in northern Italy in 1979,<br />

Guido Testa was trained in traditional methods such as casting<br />

of metal crowns using the lost-wax technique. With the advent of<br />

technology, he started to implement new tools into his workflow,<br />

such as the 3D microscope from Renfert, which allows him to<br />

see even the smallest details inside a crown.<br />

S andblasting Testa came up with the idea of using the sandblasting device<br />

as a method of material removal after he heard German dental<br />

technician Oliver Brix’s technique of carving the occlusal<br />

surface of CAD/CAM manufactured lithium disilicate units via<br />

an alternative sandblasting.<br />

to cutters or burs<br />

By Guido Testa<br />

“My therory is based on experience. Lithium disilicate is mainly<br />

used for restorations on anterior teeth. Their anatomical shape<br />

means the preparation usually has a narrow incisal area,” said<br />

Testa. “In many cases, the CAD/CAM milling or grinding tools<br />

in the milling devices cannot reach these areas well. If you allow<br />

the cutter or diamond bur to mill all the way to the end of the<br />

preparation, depending on the diameter of the bur, too much<br />

material could be removed.”<br />

If more material than neccessary is removed and the wall<br />

thickness is maintained, it reduces the space available for<br />

aesthetic individualisation and characterisation. Another option<br />

is to mill the material in the machine with small instruments,<br />

but this process takes much longer. To ensure the restoration<br />

fits perfectly on the die, it is possible to grind the inner surface<br />

of the crown manually with a diamond bur and handpiece. An<br />

innovative way would be using a sandblasting device.<br />

Preparing the crown<br />

Before fitting the crown in place, the outer surface of the die is<br />

coated with a surface marker (Fig. 1).<br />

Any interfering contacts can then be seen on the inner surfaces<br />

of the crown (Fig. 2).<br />

The crown is then checked using the video microscope EASY<br />

view 3D from Renfert with an enlargement factor of 15 or 20,<br />

in both 2D and 3D to view the starting situation. Next, the<br />

individual areas are sandblasted with a fine sandblasting device.<br />

A prerequisite for this method is that the sandblasting device is<br />

equipped with an immediate stop function, because maximum<br />

precision is needed in this material removal method. The nozzle<br />

should have a diameter of 0.4 mm, while the blasting sand used<br />

should be Cobra 25 mμ at 1.0 Bar.<br />

Fig. 6<br />

Areas that used to be trimmed with a bur and handpiece are now<br />

processed using a nozzle and blasting sand. While the principle is<br />

the same, the processing method is different.<br />

The die is first coated with a surface marker. After the crown is placed<br />

onto the die, its fit is checked visually (Fig. 3).<br />

Excess material is removed using the sandblasting device (Fig. 4).<br />

The process is repeated until the crown fits perfectly on the die<br />

(Fig. 5).<br />

The accuracy of the margin on restorations can be checked using<br />

the EASY view 3D Video Microscope (Fig. 6).<br />

When the results are completely satisfactory, the working steps are<br />

continued in the conventional manner (Figs. 7-9).<br />

A new way of working<br />

He explained his reasons for taking a new approach.<br />

1. There is no need to buy new equipment or materials.<br />

2. A lot of time is saved by using the sandblasting device to<br />

improve the internal fit of a crown.<br />

3. Less diamond grinding is needed to adapt the veneers or<br />

crowns onto the dies.<br />

4. The CAD/CAM milling machine is kept in good condition, and<br />

fewer fine milling tools with small diameters, which are costly,<br />

are needed.<br />

5. Since the crowns and veneers have an optimal wall thickness,<br />

they can be correctly built up with ceramic or characterised<br />

with stains.<br />

6. The resulting fit of the crowns are now of even greater accuracy<br />

on the prepared dies than before.<br />

“My conclusion is that one small change in the procedure can<br />

create many positive results, both in terms of savings and quality,”<br />

said Testa. “I would like to thank Renfert, the manufacturer of the<br />

fine sandblasting device with immediate stop function, and my<br />

Behind the Scenes<br />

Nathan Barber (Nate), head of Tech Art Ceramics<br />

<strong>Dental</strong> Lab in Las Vegas, United States, started<br />

using a milling machine, sintering furnace,<br />

laboratory scanner, and digitally processable<br />

materials from Dentsply Sirona in July last year,<br />

and shares what the transition has been like.<br />

Transitioning as a team<br />

Tech Art Ceramics <strong>Dental</strong> Lab was founded in 1985, and<br />

specialises in cosmetic restorations, as well as crowns,<br />

bridges, and implants. Nate Barber had worked at the lab for<br />

17 years before purchasing the company in 2016. One of his<br />

priorities was to ensure everyone in the team was taken care<br />

of so that they can carry on with their work. They include<br />

Klara, a ceramist; Antonio, who does model work; Joseph,<br />

who does scanning; and Esmeralda, who does metal, waxing,<br />

and opaquing. He considers Wes, who is knowledgeable<br />

about the dental industry and lab businesses in Las Vegas,<br />

his mentor; his wife and daughters usually help out at the<br />

front office with pick up and deliveries.<br />

Before settling on the CAD/CAM equipment from Dentsply<br />

Sirona, Barber had contacted lab friends to find out what<br />

they were using.<br />

He said, “I primarily look for what’s going to make the lab<br />

more efficient. I also look for quality and durability. When<br />

we made the switch last year, I was scared to make the<br />

transition. But now I wish we had done it sooner. We would<br />

have been ahead of the curve.”<br />

Scaling the learning curve<br />

In terms of efficiency, inLab MC X5 from Dentsply Sirona,<br />

which processes zirconia and glass ceramics, has sped up<br />

the production at Tech Art Ceramics.<br />

Behind the Scenes<br />

At the same time, Barber acknowledged that it took time to<br />

understand the scanning process with inEos X5, which uses<br />

blue light and camera optics designed specifically for dental<br />

applications, such as working models of veneers, crowns, and<br />

bridges.<br />

He elaborated, “Even though there are a lot of things you can do<br />

with digital, I still like to work with models by hand. It’s going to<br />

take time to get used to the process of scan and design. Since<br />

going digital, I’ve had to teach myself a different way of using my<br />

hands – from holding a model to holding a mouse.”<br />

Although there are different software platforms available that can<br />

help with design, Barber sees the benefit in hands-on tooling for<br />

aesthetic contouring, “I would say we use 90% digital, then 10%<br />

aesthetic contouring, tooling, and anatomy. This will change with<br />

time and practice.”<br />

The rewards of going digital<br />

Going from analogue to digital was slow at first, but Tech Art<br />

Ceramics is now on the upswing, and finds the process becoming<br />

smoother and faster, allowing the team to get work out sooner.<br />

He said, “We’re adjusting our workflow and changing the way we<br />

work. For example, Esmeralda does wax and metal finishing, but<br />

with digital, instead of waxing, she’s now grinding. You get used to<br />

your staff doing things in a certain way – but you learn to adjust.”<br />

Along with the milling machine, the sintering furnace inFire HTC<br />

speed also shortens the time it takes to turn around complete<br />

zirconia crowns and bridges, which can be done within one and a<br />

half hour. Thanks to the use of technologically enhanced heating<br />

elements, insulation materials, and sintering trays, the furnace is<br />

able to deliver time savings of up to 85%.<br />

Barber said, “Now that we don’t have to pay somebody else to mill,<br />

the money spent on outsourcing – which were getting as high as<br />

$11,000 – stays inhouse. We’ve definitely started to turn a profit.”<br />

Change can be positive<br />

Barber has plans to go completely digital. Currently using digitally<br />

processable materials such as Cercon xt Multilayer, which has an<br />

optimised colour gradient built into a proven material, he finds it<br />

more cost effective to outsource metal framework.<br />

He said, “I’d like to get a 3D printer – we would use 3D printing for<br />

models, implants, and implant supported bridges. I’m also looking<br />

to add more scanners and milling machines, so we can produce<br />

and speed up the turnaround time further.”<br />

He is looking forward to the technological development of digital<br />

dentures in the days to come.<br />

He advices fellow lab owners to be unafraid of change. “It’s taken<br />

me years to accept change. If you’re afraid, maybe you should step<br />

towards it rather than away from it.” DA<br />

Dentsply Sirona<br />

Full Dentures with inLab SW 20.0 – Simply Digital<br />

The new inLab software 20.0 from Dentsply Sirona has expanded the company’s<br />

expertise in the field of dental indications to include the fabrication of digital dentures.<br />

The software provides the dental laboratory with digital support for all relevant process<br />

steps – from accurate imaging of the bite registration with the inEos X5 extraoral scanner,<br />

through automated and careful model analysis, to the initial proposal of a possible tooth<br />

set-up and the design of the denture base.<br />

The denture optimised software also enables a new and fast scan workflow for the exact<br />

correlation of upper and lower jaw – the basis for the subsequent design.<br />

The subsequent manufacturing process<br />

can be carried out using various<br />

methods: the denture base can be<br />

milled out of a blank, such as Lucitone<br />

199 Denture Base Disc from Dentsply Sirona, or manufactured in 3D printing material<br />

such as Lucitone Digital Print 3D Denture Resin. Depending on the tooth set-up selected,<br />

the tooth arch or segments are milled out of a disc or the prefabricated IPN 3D Digital<br />

Denture Teeth from Dentsply Sirona are used. ■<br />

Due to various certification and registration periods, not all products are immediately available in all countries.<br />

The software guides the dental technician<br />

step-by-step through the entire digital process<br />

Product Highlight<br />

VOCO<br />

VOCO introduces new flowable composite<br />

The repair of defects, alongside filling of small cavities, are recurring<br />

tasks in the dental practice. The primary goal is a minimally invasive<br />

treatment to minimise the loss of healthy tooth substance. For<br />

such precise applications, dentists require a flowable material<br />

that displays the physical properties and resilience of a packable<br />

restorative composite.<br />

In addition, the product is also packed with superb physical<br />

properties, in addition to its flowability. For example, with a filler<br />

content of 76% by weight and a 3-point flexural strength of 151MPa,<br />

it attains values similar to those of a packable composite. ■<br />

To meet this need, VOCO has expanded its GrandioSO product range<br />

with a low-viscosity nano-hybrid composite – GrandioSO Light Flow.<br />

This new flowable composite, according to VOCO, is “thin-flowing,<br />

precise and high-strength”.<br />

The assets of GrandioSO Light Flow lie in the possibility of targeted<br />

and precise application with an extra fine cannula, which is even finer<br />

than a periodontal probe. VOCO added that this feature avoids the<br />

generation of excess residues, and saves on material.<br />

3Shape<br />

Facial-Driven Restorations with<br />

3Shape and Bellus3D Integration<br />

The app allows the clinician to align<br />

the face scan and the intraoral scan<br />

before sharing the aligned files into the<br />

<strong>Dental</strong> System software<br />

The integration from 3Shape TRIOS to Bellus3D <strong>Dental</strong> Pro<br />

Face scan enables clinicians to align TRIOS intraoral scans<br />

with the Bellus3D Face scan.<br />

Align face scan with intraoral scan<br />

The workflow starts with a TRIOS intraoral scan that is<br />

integrated into the Bellus3D <strong>Dental</strong> Pro app.<br />

Integrate in the 3D smile design process<br />

<strong>Dental</strong> Pro captures life-like quality 3D face scans, and<br />

provides tools to align the 3D face scan to dental surface<br />

scans to prepare them for import into dental design software.<br />

The aligned result can be used in<br />

3Shape <strong>Dental</strong> System lab software for<br />

the design of facial-driven restorations<br />

that reference patient’s individual<br />

smile and lip line for enhanced results<br />

and patient care<br />

Accelerate case acceptance<br />

Coupled with 3Shape TRIOS intraoral scanner and <strong>Dental</strong><br />

System, the integration accelerates high-value case<br />

acceptance and clinician approval by using facial-driven<br />

restorations that reference the patient’s individual smile and<br />

lip line for improved results and patient care. ■<br />

By incorporating 3D facial<br />

scans into the dental<br />

planning process, clinicians<br />

and dental labs can use the<br />

patient’s face in 3D as an<br />

integral part of the 3D smile<br />

design process<br />

Bausch<br />

Bausch adds new features to OccluSense iPad App<br />

A new iPad app version is available for the OccluSense system<br />

from Bausch, featuring new functions. The latest 1.7 version<br />

offers a simplified setup, and is able to pair the OccluSense<br />

handheld with the iPad app and the Wi-Fi network within seconds.<br />

An integrated support system has been added to provide answers to the<br />

most frequently asked questions about installation and application. A ticket<br />

system is also built into the OccluSense iPad app for users who require a<br />

direct contact with the support staff.<br />

Wider “XL” sensors BK 5035 are also available, at 60μm thin and colour<br />

coated. Like the smaller OccluSense sensors BK 5025, the colour transfer<br />

on the occlusal surfaces of the patient makes it easy to assign the recorded<br />

data. The masticatory force distribution, which can be displayed as a 2D or<br />

3D graphic with up to 150 images per second, can be saved in the patient<br />

database of the iPad app, reviewed at any time or exported.<br />

Bausch has packed its OccluSense iPad app with new features,<br />

including the improved pairing of the OccluSense handheld with<br />

the iPad and Wi-Fi network<br />

The OccluSense sensors are being used like a conventional occlusion<br />

test foil. The masticatory pressure distribution of the patient is digitally<br />

recorded in 256 pressure levels, and transferred to the OccluSense iPad<br />

app for further evaluation. ■<br />

Denticon Supports Teledentistry Team to Reach More Patients<br />

The Denticon cloud solution<br />

With the implementation of Denticon cloud<br />

solution that enables full teledentistry,<br />

clinicians at Healthy Smiles for Kids of<br />

Orange County (HSK) have been able to do<br />

away with paper charts and traditional onpremise<br />

software. X-rays are captured on<br />

site for children from low-income families,<br />

and reviewed remotely in real-time to<br />

develop comprehensive treatment plans.<br />

Dr. Harvey Lee, chief dental officer of HSK,<br />

said, “We were one of the first non-profits to<br />

begin a teledentistry programme in 2016,<br />

which wouldn’t have been possible without<br />

a cloud-based system like Denticon.” DA<br />

Additionally, the software’s advanced<br />

reporting capabilities empowered HSK<br />

with new insights into their various<br />

programmes, allowing them to track the<br />

overall effectiveness of each initiative<br />

and make more informed decisions. As a<br />

result, HSK is able to spend less time on<br />

administrative tasks and focus its efforts<br />

in giving their patients quality care and<br />

education.<br />

Through Denticon, images<br />

and patient notes can be<br />

remotely accessed<br />

Q&M Donates 50,000 Surgical Masks to Healthcare Workers<br />

Singapore-based Q&M <strong>Dental</strong> Group has donated 50,000<br />

surgical masks, along with hand scrubs, hand sanitisers,<br />

thermometers, and personal protective equipment such as<br />

gowns, goggles, and medical face shields to healthcare workers<br />

in 17 charity organisations, including Kreta Ayer Seniors<br />

Activity Centre, Lee Ah Mooi Old Age Home, Lions Home for the<br />

Elders, Singapore Children’s Society, and Thong Chai Medical<br />

Institution.<br />

Dr Ng Chin Siau, CEO of Q&M Group, said, “Even though the<br />

epidemic in Singapore is well controlled, there is still a risk and<br />

danger for those who are in the front line. As fellow healthcare<br />

workers, we empathise with our peers, and hope that our<br />

contributions can serve as a safety net for them.”<br />

Kreta Ayer Seniors Activity Centre<br />

The outbreak of the Covid-19 infection poses many challenges<br />

for all healthcare workers. The sick and elderly are reported<br />

to be more vulnerable to Covid-19. The demand for masks<br />

has led to a global shortage and rising costs, leaving some<br />

organisations vulnerable. DA<br />
