"The Great Debate" on Tooth Replacement
Bucco-palatal collapse of the post-extraction ridge is a significant challenge in restorative and implant dentistry. A variety of different approaches as well as ridge preservation techniques using tissue and augmentative materials have been proposed in this session with some of the leading clinical research teams in the field. A conceptual debate format discussing the virtues of "Early Placement" at 6 weeks (Buser & Belser Team) vs. "Immediate Placement with Dual Zone Protocols" at time of extraction (Chu & Tarnow Team) vs. "Partial Extraction Therapy" PET (Gluckman & Salama) also at the time of extraction is led by Professor Homa Zadeh of USC. This interactive session explores the current status and poses questions for the future use and indications of each proposed therapy.

The "Dual-Zone" Approach in Immediate Implant Placement
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described have enabled practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device. This protocol allows for efficient management of the patient and an attempt to maintain all original contours of the extraction site. Multiple case and retrospective case studies will be cited to support this concept.

Early Implant Placement with Contour Augmentation - Biologic Rationale, Surgical Technique & Long-Term Results
Today, the timing of implant placement post-extraction in the esthetic zone is considered an important factor which influences the esthetic treatment outcome. One of these options is early implant placement after 4 to 8 weeks of soft-tissue healing. The purpose of this presentation is to present data and to analyze the stability of esthetic treatment outcomes in patients following single-tooth replacement in the anterior maxilla using the concept of early implant placement with simultaneous contour augmentation. Special emphasis will be placed on assessing the stability of the facial mucosa, since it directly depends on the stability of successful contour augmentation by GBR and to compare it to currently utilized immediate techniques like Dual Zone Therapy (Chu & Tarnow) and Partial Extraction Therapies (Salama & Gluckman).

Team Work: The Role of the Restorative Dentist in the Multidisciplinary Practice
In this presentation, Drs. Conti and Rossi share their experiences in treating challenging cases from a comprehensive multidisciplinary perspective. Emphasis will be placed as to when and how the restorative dentist enhances overall periodontal and esthetic therapy.

Partial Extraction Therapy and Immediate Loading in Clinical Practice: Synergy for Success
This presentation will focus on the application of PET techniques and immediate loading in daily practice. A brief introduction will be presented outlining the concepts, and the benefits in combining both techniques. This will be followed with a review of clinical cases ranging from single unit to full arch implant rehabilitations. Lastly, recommendations will be presented to the viewer in order to facilitate incorporation of these techniques into clinical practice.

The Next Challenge in Implant Dentistry: The Rise in Peri-implantitis and What Can We do About It?
In this presentation, Dr. H. Ryan Kazemi will discuss etiologies for implant failure due to peri-implantitis, its preventive measures, and what treatment modalities work best. He will also describe a new classification to help clinicians choose the optimal treatment approach.

Alveolar Ridge Preservation and Reconstruction
Periodontal plastic surgery procedures designed to reconstruct deformed, partially edentulous residual ridges were introduced to the dental profession between 1971 and 1986. They have been revised and refined to their current state of development, where they now occupy a major place in the reconstructive armamentarium. Before these concepts were developed, it was generally believed that it was impossible to surgically reconstruct deformities in the partially edentulous ridge. Deformities were filled…

The Socket-Shield Technique to Support the Buccofacial Tissues at Immediate Implant Placement
Tooth loss and subsequent ridge collapse continue to burden restorative implant treatment. Careful management of the post-extraction tissues is needed to preserve the alveolar ridge. In-lieu of surgical augmentation to correct a ridge defect, the socket-shield technique offers a promising solution. As the root submergence technique retains the periodontal attachment and maintains the alveolar ridge for pontic site development, this case report demonstrates the hypothesis that retention of a prepared tooth root section as a socket-shield prevents the recession of tissues buccofacial to an immediately placed implant. The socket-shield technique is a highly promising addition to clinical implant dentistry and this case report is among the first to demonstrate the procedure in clinical practice with a 1-year follow up.

Biologic Shaping
Creating proper space for biologic width ensures that the new margin will not infringe upon the periodontal complex and reduces the likelihood for future inflammation.
