Digital workflow for full-arch implant dentistry 2.0

(09.30-10.45)

The progressive shift towards implementing digitally driven technology in reconstructive dentistry is obvious. Compared to conventional methods, the ultimate goal of digital technologies is to improve the quality and capabilities in examination, diagnosis, and treatment of the dental patient. It is still questionable, however, whether such digital tools facilitate improved accuracy in data acquisition and assessment, superior efficacy in treatment planning, and more controlled and faster manufacturing process. This presentation will provide an overview about disruptive technologies in implant rehabilitation and discuss different possibilities and advantages when using innovative digital workflows. Focus will be given to new workflows facilitating synergy between surgical, functional and esthetic components in full-arch cases.

Decision making in implant prosthetics – what have we learned from wrong decisions and complications?

(11.30-12.45)

For successful implant prosthodontics safety, long-term performance, costs and the esthetic outcome are the main factors for the decision-making process. Important achievements in this field have undoubtedly been the introduction of digital impressions, 3D planning and designing software, 3D printing and CAD/CAM technology in implant dentistry. The digitalization process in implant prosthodontics has introduced a lot of new opportunities and material options, which help solving currently clinical and dental laboratory challenges.

As many of these techniques are already available in clinical practice it is of great importance to evaluate the advantages and disadvantages of these techniques and materials in clinical applications. Hence, the aim of this lecture is to discuss and compare CAD/CAM in prosthodontics from start to finish with the conventional workflow and conclude with the today’s recommendations.

Bone and soft tissue augmentations in the esthetic area: a technique-sensitive procedure

(15.45-17.00)

Bone and soft tissue augmentation are necessary to compensate for, or prevent tissue deficits around implants placed in the esthetic region. Lack of bone can either make the placement of implants impossible or it is a limiting factor for an optimal esthetic result.

Guided Bone Regeneration is a proven technique for such bone augmentation. When used correctly and with the right materials, the desired result can be achieved with good long-term results. However, the GBR technique is very technique-sensitive. Mistakes which prevent success can be made starting with the incision technique over the membrane adaptation to tension free flap adaptation.

But we learned that bone augmentation alone doesn’t give us the perfect tissue volume. Soft tissue augmentation appears to be of enormous importance, particularly for long-term success. Depending on the initial situation, various techniques are successful if they are applied correctly.

This presentation will discuss the goals of the GBR and soft tissue augmentation techniques, especially in the aesthetic field, as well as which steps in the surgical phase are really essential for success.

Treatment of open-bite malocclusions with clear aligners – from diagnosis to long-lasting results

(17.00-18.15)

Open-bite is one of the most common malocclusions in teens and adults and one of the most difficult to treat and retain.

The lecture will cover different methods to overcome the open-bite, address the causes and provide tips for successful retention.

Technical diagnostic and esthetic approach

(10.00-11.15)

Great improvements have been made in the field of esthetic restoration in the last few years. This evolution derives not only from esthetic requirements of the patient, but also from a good relationship between the dentist and the dental technician. The clinician should know technical steps to make the process easier the imagination of the technician and the laboratory should know the clinical operative steps with the possible difficulties in the mouth, so that the technician can develops more techniques to help the dentist in his work. In this way it is possible to plan the case that will also give to the patient the possibility to perceive and understand clearly the treatment proposed. Technically the numerous possibilities for anatomical tooth reproduction will be examinated. A new system that will be enables dental professionals to go beyond the usual creative standards in esthetical rehabilitation: the principal tooth forms and their characteristics will be analysed and the discussion will lay groundwork for the introduction of a new tooth-form classification called Dental Anatomical Combination. Comparing to the face of the patient several factors will be evaluated when designing an individual customized dental restoration. Other new digital systems will be evaluated in order to create an individual tooth shape for the patient and the subsequently customized smile.

The application of this new system and subsequently ceramic layering procedures will be demonstrated via a clinical case report. All the rehabilitations simple or complex are created with precision using the stereomicroscope to achieve the planned result and increasing the longevity of the restoration.

The objective of this topic is to provide valuable information to support the prosthodontic team in the treatment of the various clinical cases. Detailed analysis of the most significant clinical and technical procedures will be described, beginning with the clinical diagnosis and subsequent diagnostic wax up, then progressing to the correct use of the provisional restorations, which are fundamental in the conditioning and correct development of the soft tissues, as well as in the achievement of the functional and esthetical objectives.

Optimizing the restorative-tissue interface in challenging esthetic treatments

(12.00-13.15)

In order to achieve a harmonious esthetic result of complex restorations at the smile zone, not only the restoration design and material should be carefully selected, but the abutment type, design and color should be carefully prepared - in order to achieve integration of the whole restorative complex with the surrounding tissue; whether of a natural tooth (vital or non-vital), or an implant.

One should plan ahead the different phases of the perio-restorative treatment in order to end up with a harmonious natural looking result, by choosing the most suitable treatment for each site, so that the combined abutment-crown complex will blend with the adjacent dentition and with the surrounding vital periodontium, in an esthetic and healthy manner.

State of the art strategies will be presented where different abutment types of teeth and implants are to be restored, utilizing diverse laboratory and clinical techniques. The concepts of Model Based Cervical Design and Cervical Contouring will be presented and analyzed in a variety of esthetically challenging clinical cases.

Different perspectives of treatment planning

(14.30-15.45)

Even if we divide dentistry into specialities, it is necessary to look at the phenomenon as a whole. Anamnesis, diagnosis, treatment options, surgical preparation of the infrastructure, combination of hard tissue (bone) soft tissue (mucosa), functional fit and aesthetics. Achieving such a journey is only possible with teamwork.

To make a smile design; it is necessary to see the deficiency, understand the situation and to know the ideal outcome.

Every detail should be paid attention to in order for the aesthetics to be close to perfection during and after the surgical procedure. The effects of local and systemic factors should be planned as a whole. The perfect plan is possible to determine the negative factors that will affect the result over time.

- From stem cell to immune response,

- From geometric design to function,

- From emotions to hormones,

- Everything from biomaterial to biological compatibility should be considered in treatment planning.

In order to turn your smile designs into a sincere smile, it is necessary to see the whole very well.

«From Evidence Based Treatment Planning to Digital Diagnostics, Patient Communication to a Predictable Final Outcome - An Interdisciplinary Approach.”

The recent digital technology offers numerous new and efficient options for planning and conducting implant and restorative treatments.

Within digital dentistry cone beam CT scanning and optical impressionning are the first steps towards a digitalization of the patient’s intraoral situation. The resulting digital files are then used for the virtual planning and guiding implant placement.

The main goal is to initially define and later on follow a systematic and evidence based treatment plan, in simple as well as more complex dental rehabilitations.

In the restorative phase digital dentistry is used to virtually design reconstructions, which thereafter can be milled out of prefabricated blanks of different materials with aid of CAD/CAM systems. Evenmore, these CAD/CAM reconstructions can either be made in a centralized production facility or chair-side in the dental office.

The digital systems available today offer numerous advantages, like e.g. the precision of the reconstructions. A high number of studies has demonstrated good accuracy of the current subtractive manufacturing, i.e. the computer-aided milling or the grinding of ingots. More recently, additive procedures have been introduced. Stereolithography, laser sintering or printing of materials like wax, resins or metals has shown to be even more precise than the subtractive manufacturing. Furthermore, the additive fabrication of reconstructions may even be more efficient due to the fact, that less time may be needed for the fabrication and no material excess is produced.

Finally, the „digital workflow“ and the associated additive procedures, is not only interesting for the planning and fabrication of implant reconstructions but also for a better patient/dentist communication. As an example, 3D prosthetic diagnostic files of digital wax-ups or set-ups may be printed out of resin and used for try-in in the clinical situation.
