Immediate implantation:
Different concepts and provocative cases *)
Today, the concept of immediate implant placement after tooth extraction represents an essential part of dentistry. Through
immediate implantation, the number of surgical interventions can be kept to a minimum, patient discomfort is drastically
reduced, alveolar bone can be spared from resorption, cost effectiveness and chair time are influenced positively and patient
satisfaction is improved. But what looks very easy when performed by a specialist can prove quite tricky sometimes.
A number of rules have to be followed in order to prevent complications and failure. The presentation focuses on these
details in a very practical way and demonstrates the do’s & don’ts of immediate implantation as understood and practiced
today by means of several clinical cases.
Dr Rudolf Fürhauser (AT)
was born in Vienna, Austria, in 1959. After studying medicine, he worked as a general practicioner
for several years. In 1989, he received his degree in dentistry from the Vienna University

Dr Fürhauser was Assistant Professor at the Prosthodontic Department of the Dental School of
Vienna. He has been a member of the Academy of Oral Implantology since 2004 and currently
runs a private practice together with Doz. Dieter Busenlechenr, Prof. Dr Robert Haas, Prof. Dr
Georg Mailath-Pokorny and Prof. Dr Georg Watzek in Vienna. His main areas of focus include
implant prosthetics, phonetics, esthetics, immediate implant restoration and biomechanics.
Single-tooth and full-arch restorations using CAD/CAM
technology – landmarks and protocols *)
Standardized protocols are essential for the reconstruction of the teeth’s functions – for esthetics, phonetics and mastication.
In the presented concept, the initial status of the patient is recorded precisely and changed in a standardized way if necessary.
This process requires landmarks and treatment protocols. CAD/CAM procedures enable the desired shape to be transferred to
the definitive reconstruction, which is very important for the predictability of treatment success.

Esthetics in direct restorative procedures with composite:
The camouflage trick
The secret to successfully restoring anterior teeth with composite resin lies neither in the correct selection of shades nor in the
application of a special layering technique. The “invisible” filling does not really exist, as we will probably never be able to
produce a synthetic material that is capable of fully mimicking the optical properties of naturally grown tissue. Therefore,
certain tricks are required to disguise the transition along restoration margins. The lecturer uses two ways to achieve this goal:
the imitation of shade anomalies and the mimicking of natural surface texture.
Before starting to fabricate a restoration, the different characteristics of the natural tooth need to be studied in depth, and
this knowledge needs to be applied in the fabrication process. An essential pre-requisite for practicing esthetic dentistry, not
only in conjunction with composites but also with all other techniques, is learning to see! In this context, the ageing criteria
of natural teeth are identified, based on which a checklist is established whose items can be ticked off successively. This helps
to ensure predictable restorative results.
Clinical aspects of chairside CAD/CAM restorations
CAD/CAM systems (for example the CEREC ® 3D system) that can be used for the chairside production of all-ceramic restorations
are an interesting option for both the dentist and the patient. Ceramic materials for CAD/CAM processing, their indications
as well as the clinical performance of CAD/CAM-fabricated restorations (veneers, inlays, partial crowns and crowns) are
discussed in this lecture. Further developments are highlighted.
In implant planning, the CEREC CAD/CAM system and a cone-beam CT (CBCT) system can be usefully combined, enabling
the dentist to analyze all dimensions of the bony structures. Optical impressions of the edentulous areas and the adjacent
teeth are obtained with an intraoral camera directly in the patient’s mouth. After the generation of a 3D model, the virtual
implant crown is designed. This data is combined with that obtained with CBCT. Proper implant planning should take the
desired prosthetic outcome into account. A surgical template fabricated using a CAD/CAM system will assist with implant
placement. A new development is the production of CAD/CAM implant superstructures in one appointment.

New esthetic opportunities in the fabrication of metal-free
restorations
In the past few years, patients have become increasingly interested in esthetic restorative procedures. As a result, the demand
for all-ceramic restorations has risen greatly. By employing innovative ceramic components, such as the new translucent lithium
disilicate materials, we can offer new esthetic options for the creation of exceptional, true-to-nature restorations even
when conditions are not ideal for an excellent outcome. The need for an exchange of information between the patient and
the clinician and between the clinician and the technician are demonstrated by means of the step-by-step documentation of
several clinical cases involving anterior teeth. Finally, the characteristics and advantages of the latest generation of metal-free
materials are demonstrated.

Esthetic approach:
Minimum loss of biological structure – maximum esthetics
Due to biological, biomechanical and esthetic reasons, bonded ceramic veneers are the solution of choice in the restoration of
anterior teeth. They have a prognosis similar to that of implant restorations. However, the success of this type of treatment
remains deeply dependent on the operator. Over the past decade, particular emphasis has been placed on facilitating and
standardizing the fabrication of laminate veneers in order to achieve reproducible results and make them less operator
dependent. Within the framework of treatment planning, the fabrication of a provisional, which has to be approved by the
patient, represents an essential step. The provisional can also be used as a control and reference in the fabrication of the final
restoration. In the lecture, we will also discuss the management of non-vital teeth and the placement of fiber posts using
conservative treatment procedures. In addition, we will show that the concept of partially bonded restorations can also be
applied for more complex cases, e.g. in the rehabilitation of teeth with severe abrasion and erosion. The complete reconstruction
of teeth with implants using the same materials will also be shown. The esthetic expectations of patients seem to be very
similar. When discussing appearance, they usually indicate a lot of details. Therefore, we have to analyze patient requirements
by asking the right questions. Dentists and dental technicians have to communicate with the patient and interact understandably
to gather the information required to create customized restorations. Modern dental photography can be used to
enhance communication, even though indication, the selection of materials and technical experience continue to be of crucial
importance.

CEREC ® – Esthetic illusions or reality:
“CAD/CAM abutments”
In the oral rehabilitation with multi-component implants, we can identify two potential problem areas: the primary problem
area (implant abutment) and the secondary problem area (abutment crown). These two areas are not bacteria-tight.
Moreover, complete removal of excess temporary cement cannot be achieved. Very frequently, however, the desired esthetic
result cannot be attained with zirconium oxide abutments.
Customized abutments fabricated with IPS e.max ® using the CAD/CAM technique may provide a viable solution to this
problem. In this lecture and workshop, the planning, CAD/CAM-fabrication and customization of abutments will be discussed
and their esthetic implementation will be presented.

Periodontal therapy and peri-implantitis treatment using
the new Vector Paro System
The characteristic feature of the Vector system is a ring-shaped oscillating resonance body driven by an ultrasonic motor in a
dental handpiece. An instrument attached at 90° offset to the handpiece longitudinal axis is therefore moved up and down
linearly, passively driven by the ring. Due to this patent registered technology, an efficient removal of concrements and
cementum can be provided without any damage of the cementum and dentin surface. In addition, the use of hydroxyapatite
particles increases the degree of efficiency with virtually painless treatment.
The new Vector Paro device combines the classical scaling technology with a highly sophisticated handpiece for periodontal
treatment. The complementing instruments enable a broad range of therapeutic aspects.

Extensive composite restorations ranging from cusp
replacement to direct crowns
In the restoration of single teeth, composites have become a viable alternative to full ceramics. Scientific data increasingly
support the use of resin-based composites even for large restorations including cusp replacement or full crown build-up.
However, the clinical procedure imposes a range of challenges on the operator. Matching colour and translucency in the fabrication
of anterior restorations, creating the correct occlusal morphology and controlling shrinkage stress in posterior restorations
are only some of the points that must be addressed by the dentist. The lecture focuses on the critical clinical steps,
explains the most commonly encountered failures and gives numerous clinical tips and tricks.

Surgery and prosthetic restorations in the esthetic zone *)
The placement of dental implants in the esthetic zone is one of the most challenging fields of implantology. Detailed knowledge
of the various concepts on which the surgical and prosthetic techniques are based is essential. To avoid an unfavourable
outcome, each patient selected has to be carefully analyzed. The amount and quality of bone in the horizontal and vertical
dimension of the anterior maxilla, the biotype of the gingiva, the exposure of gingiva during smiling and several other parameters
have an influence on the type of treatment protocol that needs to be chosen. The techniques necessary to create an
ideal situation for a successful outcome include atraumatic extractions, preservation of the socket, formation of papillae with
ovate pontics, bone grafting in all directions, connective tissue reconstruction and grafting. An understanding of the principles
for maintaining a healthy biological width is necessary. In this presentation, a team approach (including surgeon, dentist
and dental technician) will be demonstrated. Furthermore, the speakers will address implant treatment in the anterior maxillary
esthetic zone, presenting both theoretical aspects and case reports.

Computer-aided esthetics – fiction or reality?
Today, a lot of restorative procedures are primarily driven by esthetics. We have to keep the loss of healthy tooth structure to
a minimum and fulfill the high expectations of our patients. The challenge is to help patients visualize the restorative result
prior to starting the treatment in order to ensure patient compliance. When esthetics are of prime importance, the patient
must be actively involved.
By means of the digitization of the initial situation, a virtual wax-up can be created on the PC screen following diagnosis. This
enables the final result to be visually represented in a three-dimensional manner. On-screen design allows a realistic, reversible
preview of what will be achieved in the course of the treatment.
Following virtual design, a mock-up can be milled from polymer blocks. Polymer materials offer a suitable range of shades,
provide sufficient esthetics in the short-term, possess adequate physical properties and are easy to adjust. They allow a blueprint
of the definitive situation to be provided. Apart from showing the changes to the teeth, the mock-up also enables the
effect of the restoration on the gingiva and the soft tissues including the lips as well as the entire smile to be evaluated.
A choice of ceramic materials with sufficient strength and the optical properties to achieve the promised result is essential.
Already in the past, lithium disilicate ceramics were offered in a wide range of translucencies and shades. In the future, this
material will be further improved and thus allow even more natural-looking results to be achieved.

The secret world behind the canine tooth:
function and esthetics
The importance of occlusion and function, especially in the posterior teeth, for all parts of the stomatognathic system, is generally
dramatically underestimated. The knowledge of occlusion and function has been investigated and laid down in countless
scientific papers. A thorough diagnosis is the key element for treatment planning and therapy. The general aim for all
patients, independent of the Angle class, is to ensure the least muscle activity during nocturnal clenching and bruxing. It is a
fact that the most anterior guidance serves this goal best. All eccentric contacts in the molar region must be seen today as
pure pathology.
In diagnosis and treatment, the skull-related mounting of the upper cast and the joint-related mounting of the lower cast are
pre-requisites. The realization of the fundamental aspects of gnathology will be demonstrated step by step. Esthetics are not
only important for the front teeth, but, at least in the upper jaw, as far as to the first molars. When creating a computeraided
sound occlusion, esthetics evolves by itself.
Long-term follow up documentations, up to 35 years, will demonstrate the effectiveness of this logistic approach. The question
whether excessive bruxers can be treated long term, predictably and successfully without chipping, with all-ceramic
restorations will be discussed in detail.

The synergistic use of dental materials choosing a team
approach: clinical and laboratory aspects
Nowadays we have many different materials that can be used in the restoration of teeth. The dentist and technician must
approach the treatment as a team and know how to combine the different restorative materials. An esthetic, biological and
functional outcome will benefit from their synergistic use. The concepts of esthetics and resistance should always be on our
mind.

The invisible composite filling (tips and tricks for your daily work)
Profound knowledge of the fundamental technical and esthetic aspects as well as an understanding of the layering technique
is essential to achieving predictable and reproducible restorative results. The creation of functionally and anatomically correct
occlusal surfaces contributes to a long life of the restorations as premature contacts and hyperbalances are avoided.
Main topics of the course:
○ How to avoid the formation of marginal gaps or cusp fracture by using a targeted layering technique and taking the
C factor into account;
○ How to prepare proximal surfaces using oscillating instruments without damaging the adjacent teeth;
○ How to reliably achieve tight proximal contacts;
○ How to reduce the cumbersome grinding of premature contacts to a minimum;
○ How to create wear-resistant occlusal surfaces by taking functional morphological principles into account.

CEREC ® – Esthetic illusions or reality:
“CAD/CAM abutments”
In the oral rehabilitation with multi-component implants, we can identify two potential problem areas: the primary problem
area (implant abutment) and the secondary problem area (abutment crown). These two areas are not bacteria-tight.
Moreover, complete removal of excess temporary cement cannot be achieved. Very frequently, however, the desired esthetic
result cannot be attained with zirconium oxide abutments.
Customized abutments fabricated with IPS e.max ® using the CAD/CAM technique may provide a viable solution to this
problem. In this lecture and workshop, the planning, CAD/CAM-fabrication and customization of abutments will be discussed
and their esthetic implementation will be presented.

Periodontal therapy and peri-implantitis treatment using
the new Vector Paro System
The characteristic feature of the Vector system is a ring-shaped oscillating resonance body driven by an ultrasonic motor in a
dental handpiece. An instrument attached at 90° offset to the handpiece longitudinal axis is therefore moved up and down
linearly, passively driven by the ring. Due to this patent registered technology, an efficient removal of concrements and
cementum can be provided without any damage of the cementum and dentin surface. In addition, the use of hydroxyapatite
particles increases the degree of efficiency with virtually painless treatment.
The new Vector Paro device combines the classical scaling technology with a highly sophisticated handpiece for periodontal
treatment. The complementing instruments enable a broad range of therapeutic aspects.

Single-tooth and full-arch restorations using CAD-CAM
technology – protocols in daily routine
In this workshop, standardized protocols will be presented which are helpful for the reconstruction of the teeth’s functions –
for esthetics, phonetics and mastication. The initial status of the patient is recorded precisely as it provides invaluable information
and will be changed in a standardized way if necessary. This process requires landmarks and treatment protocols. The socalled
“try-in bridge” occupies a central position in creating a form considering all functions prior to the design of the final
framework. By means of CAD/CAM technology, this form can be transferred to the definitive reconstruction, which ensures
high predictability and patient acceptance.
