Info

Dental Profile CEREC from Dentsply Sirona has been very successful in the market for more than 30 years. Through further development of both the hardware and the software, the company made intraoral scanners popular in the first place. About 35,000 CEREC units worldwide and a digital impression taken every four seconds with one of Dentsply Sirona’s intraoral scanners, send a clear message. When introducing a new product to the market, there are always considerations behind the development. From their customers, Dentsply Sirona knows that flexibility and freedom of choice for every treatment is very important. They also know that digitalisation is an important matter for all of their users. With this in mind, Dentsply Sirona continues optimising digital workflows available to dentists, independent of CEREC, thereby giving users many more options in terms of intraoral scanners. In addition to restorative treatment, Dentsply Sirona also wants to improve implantology, orthodontics and endodontics. The company knows which features are important to its customers: easier to handle, considerably faster and, of course, more accurate than ever before. After speaking to Dr. Alexander Völcker, Dentsply Sirona’s, Group Vice President CAD/CAM and Orthodontics, at the Dentsply Sirona World 2018, Dental Asia also had a one-on-one interview with Dr. Frank Thiel, Vice President R&D CAD/CAM and Orthodontics, at the product launch of its new intraoral scanner - Primescan - at Klassikstadt Frankfurt, Germany in February 2019. Read on to know more about Dr. Thiel’s role, consolidation of Strategic Business Units (SBUs), the new intraoral scanner, current trends and Dentsply Sirona’s plans for continued growth and expansion. Optimising organisational structure According to Dr. Thiel, after the merger of Dentsply and Sirona three years ago, Dentsply Sirona has constantly been optimising their organisational structure to fully utilise all their resources and to continue to provide the optimum solutions for users. Early this year, when Dr. Alexander Völcker took over the position as Group Vice President CAD/CAM & Orthodontics, Dr. Thiel became the Vice President R&D CAD/CAM and Orthodontics. Dr. Thiel has been in the CAD/CAM business for almost 15 years and he looks forward to contributing to many more future developments. “I started with SBU CAD/CAM 15 years ago and I am heavily focused on the business. My role allows me to utilise my expertise and my experince in developing tools that empower dental professionals,” Dr. Thiel explained. Consolidation of CAD/CAM and orthodontic SBUs Early this year, Dentsply Sirona shifted its focus from promoting mainly full-chairside-systems consisting of an intraoral scanner, the design software as well as a milling unit to also focusing on Digital impressions (DI) alone. Looking at the orthodontic workflow, one of the major key components is providing clear aligner solutions. And at every beginning of orthodontic treatment, digital impressions are taken. “Digital impressions are the starting point for both CAD/CAM and orthodontics. Therefore the recent combination of these two particular SBUs is an advantage. It drives a more unified product strategy and more focused product development by bringing together SBUs with similar characteristics” The development of intraoral scanners Dr. Thiel briefly discussed that the development of intraoral scanners by the company begun more than 30 years ago with the introduction of CEREC. The Bluecam was launched in 2009, still with some technological limits but definitely state-of-the-art at that time. In particular, using the powder system inside the mouth can be tedious as water and saliva easily washes of the powder during intraoral scanning. However, in 2012, Dentsply Sirona introduced the Omnicam – the smallest intraoral scanner at that time. It was a great step forward, as it was used powder-free and scanned in colour. The Omnicam was designed to work perfectly with the CEREC workflow. “Back then, having a powder-free scanning system as well as scanning in full colour was a breakthrough. Before Omnicam, we could not distinguish teeth from gingiva. Omnicam is a very good scanner and turned out to be a huge success,” he shared. Dr. Thiel revealed that as time went by, the users and the market demands have evolved. There was still a lot of potential in scanner technology that the company wanted to exploit. With these demands in mind, Dentsply Sirona introduced the CEREC Ortho software in 2015. The company never rested on its laurels and constantly researched and developed based on the needs of dentists and patients: speed, accuracy and ease of use. The new intraoral scanner Primescan Based on all these aspects, Dentsply Sirona developed the new Primescan which was recently launched in February 2019. Primescan is no doubt a game changer in digital dentistry with its significant features, taking digital impression to a higher level. With Primescan, it is possible to capture an entire upper jaw in under 30 seconds, and a full arch scan in less than a minute. During the scanning process, the dynamic lens completes more than 10 movements per second, thereby enabling the “Dynamic Depth Scan” – capturing more than 1 million 3D data points per second. Thanks to its Intelligent Processing which filters, processes and compresses the high volume of data models can be calculated faster. 30 DENTAL ASIA MARCH / APRIL 2019
Dental Profile The high-precision Smart Pixel Sensor of Primescan captures data at an extremely high resolution and assesses the contrast in each pixel. For every 3D image, Primescan consolidates more than 50,000 images per second, thereby offering a level of scanning precision that has never been achieved before. The new, patent pending technology in the form of optical high frequency contrast analysis is used to calculate the 3D points, resulting in an increased level of accuracy. Additionally, Primescan enables a flexible, intuitive and very simple scan procedure, allowing faster access to tooth surfaces without the need for significant tilting. The captured images are calculated in a flash and put together without any visible scan interruptions. Lastly, Primescan is an intraoral scanner that can be subjected to all necessary hygienic reprocessing (wipe disinfection, autoclaving, hot air sterilisation, high-level disinfection). Thanks to the smooth surfaces the hygienically critical areas, which are often difficult to clean, can be reprocessed safely, quickly and easily. “When it comes to accuracy, Primescan is the most accurate scanner on the market. This has also been proven by a recent study at the University of Zurich (Mehl et al. 2019). When it comes to speed, a full jaw (upper and lower) only takes about a minute . We are at a point where we can say, digital impressions are in no way inferior to conventional impression taking. Primescan is a pivotal product for us. Hence, the question is not what can the device do but rather what can you not do with Primescan,” Dr. Thiel confidently stated. He added that Dentsply Sirona represents intelligent workflows and Primescan enables access to many digital workflows, which, above all, can be safely and easily implemented. Specifically, this means that, after the intraoral scan, the user can decide what to do with it. The company offers a high level of flexibility. For example, the user can send the data to a laboratory, and the Connect Case Center (former Sirona Connect) is available for this purpose. Communication with the dental technician takes place simply, directly and securely via the Connect Case Center Inbox. Another option is exporting the scan data to treatment planning software. This now also includes SureSmile for the manufacture of therapeutic braces. And of course, the dentist can continue to design and manufacture the restoration in the practice. “The fact is whoever works with Primescan is not under any commitment to a specific option. An upgrade is possible at any time, but it is not absolutely necessary. With the Connect Case Center Inbox, any lab can have full access to the case data. For the dentist that means freedom and flexibility when working with a lab. Besides a chat function enables direct communication about the case via the portal.” Dr. Thiel shared that all the feedback from first time users/testers of Primescan were all overwhelmingly positive. Primescan is slightly heavier and larger than Omnicam but this was not an issue for users due to its speed, accuracy and ease of use The time inside a patient’s mouth is considerably shortened. Furthermore, it was highlighted that female dentists found Primescan easy to handle which is important as more and more female practitioners are joining the field of dentistry. A new age of digitalisation Dentsply Sirona has continued to provide digital products for over 30 years and has always kept the mission of empowering dental professionals to Digital impressions with Primescan: easier, faster and more accurate than ever before.
