The Unknown Unknowns of 3D Imaging in Periodontics

Presented by Dr. Bruno Azevedo DDS MS

Program Description
Cone-beam computed tomography or Cone Beam (CBCT) is an indispensable tool for diagnostic imaging in modern dental periodontology practice. CBCT imaging’s challenge is the users’ lack of training and understanding of basic and advanced imaging principles. After all, when reading a scan, there are known knowns; there are imaging patterns that we know that we know. There are known unknowns; that is to say, there are things regarding 3D imaging that we know that we don’t know, and there are unknown unknowns or 3D imaging things that we do not know we don’t know. Understanding the imaging principles behind high-resolution 3D imaging volumes should enable professionals to plan and execute dental implant procedures appropriately and safely, ensuring a predictable clinical and prosthetic outcome. The jaws’ CBCT scans provide dentists with greater diagnostic precision of dental and bone morphologies and related pathologies than the conventional 2D intraoral digital image. 3D imaging is emerging as the scaffold for upcoming technologies such as 3D printing, dynamic navigation, and surgical guides. It is being applied to better understand the healing process associated with grafted sites and soft tissue surgeries.  Using clinical cases, we will demonstrate the effect of task-specific rendering filters and discuss when they should be applied in clinical dentistry and the impact of newly developed realistic 3D rendering for imaging diagnosis and bone assessment.

Objectives

• Be familiar with current technological advances in CBCT hardware and software.
• Understand basic and advanced 3D rendering reconstructions of CBCT data
• Understand Imaging Artifacts and how to overcome them.
• Use contemporary 3D imaging navigation techniques to minimize interpretation time and maximize diagnosis.
• Recognize advanced 3D anatomy and pathologies of the jaws and paranasal sinuses.
• Integrate information presented in this course into efforts to improve the imaging skills of the participants.

The Digital Approach to Full Arch Implant Dentistry

Presented by Martin Wanendeya, DDS.

Program Description
Digital dentistry has become very common in implantology and we have now reached a point where many clinicians routinely use digital workflows for single and multiple implant restorations.

Digital dentistry has allowed better planning, treatment and delivery of this treatment modality and now, this is possible with a fully digital workflow from initial diagnosis to final delivery. But we are still at a point where the common perception is that intra oral scanners cannot be used for full arch dentistry as they are perceived to be to inaccurate for this use.

• When will intra oral scanners be accurate enough to use for full arches?
• What are the workflows that we need to use for full arch fully digital restorations?
• What are the advantages of fully digital, partly digital and analogue full arch workflows?

Objectives

• To understand fully and partially digital workflows and their use in practice
• To understand the strategies for digital full arch restorations
• To understand the advantages and disadvantages of full arch full digital workflow

Peri-implant Tissue Reconstruction in the Aesthetic Zone

Presented by Dr Ricardo Kern DDS

Program Description
Quality and design of the tissues surrounding implants are not only important for long term maintenance, but fundamental for aesthetic purposes. Delivering “pink free” restorative solutions over implants requires the full presence of the gingival contour, a natural emergence profile and respect for aesthetic proportion ratio of crowns and bridges. Achieving the perfect balance between pink and white contour is a Key Point.

Surgical implant sites can require different approaches and techniques. For example, the approach required for treating cases of immediate extraction/implant placement/temporization is completely different compared to cases of a healed crest/site when the volume of the tissue is compromised.

Immediate extractions can present an outstanding initial situation of tissue contour. In these cases, the preservation of the gingival “frame” is the goal for treatment. Atraumatic extraction, proper 3D position of the implant, primary stability, gap grafting and soft tissue phenotype modification are on the protocol of immediacy in fresh sockets. But, much more than these basics is the knowledge of peri-implant remodeling after extraction, abutment/provisional design and small surgical maneuvers which can boost the aesthetic results and long term tissue stability.

Treating deficient, healed sites can be a unique challenge in terms of tissue reconstruction. A successful bone reconstruction is only one of the necessary steps in these cases. Vertical soft tissue grafting techniques and knowing how to create the proper shape of the gingival contour after the healing period requires specific knowledge of tissue manipulation and conditioning protocols.

Objectives

• Address the main workflow for dental implants with “pink free crowns” in the aesthetic zone.
• Review protocols for immediate placement through reconstruction cases.

Mucogingival FP1 Approach in Full Mouth Implant Rehabilitations

Presented by Paulo Carvalho, DDS

Program Description:
Patients demands and expectations in Implant Dentistry are getting higher and higher nowadays. They chase even more aesthetic results with less morbidity possible and in a shorter time. Different approaches and prosthetic designs are possible when it comes to full mouth rehabilitations. In some cases, vertical bone reduction is required in order to hide the prosthetic transition in the smile line or to promote enough vertical prosthetic space. Very often patients find those FP3 prosthetic solutions unnatural, uncomfortable and difficult to clean. A mucogingival approach with FP1 prosthetic design (no artificial gum) allows the clinician to restore the lost tissues architecture around implant-supported rehabilitations, providing the patient the desired aesthetics and comfort. It takes a more complex and precise reverse planning mastering implant 3D positioning and soft tissue grafting procedures. Provisionals are crucial as they will manage the emergence profiles all the way through the final restoration.

Precision of digital workflow provides much better results in such sensitive procedures, it enhances the aesthetic outcome and avoids some further reconstruction procedures comparatively with conventional approaches.

Not only in surgical stages but also on the prosthetic phase, the use of digital prosthetic tools will guide the clinician through a more predictable and comfortable path so that the final result is fitter and closer to what was planned from the beginning.

Objectives

• To discuss different approaches and prosthetic designs possible when it comes to full mouth rehabilitation
• Tissue Development in FP1 Prosthetic designs
• The workflow of digital, surgical and prosthetic components of these full arch rehabilititations
