Summary:
Implant dentistry, one of the most predictable treatment alternatives offered to patients who are missing teeth can be enhanced by thorough pre-surgical diagnosis and treatment planning efforts by all members of the implant team. Conventional radiologic techniques including periapical and panoramic radiographs are limited by the two dimensional interpretation of existing hard and soft tissue. The inherent distortion factor can misrepresent bone topography in critical areas associated with vital anatomy or potential implant sites. Advances in diagnostic radiological techniques improved with the introduction of CT scan technology for dental applications. The enhanced diagnostic range of this evolving technology empowers the clinician with necessary tools to avoid potential complications associated with implant dentistry. The purpose of this paper was to identify valuable aspects of interactive CT through documentation and identification of several important issues; (1) revealing difficult to detect pathology, (2) correct assessment of bone trajectory to avoid iatrogenic damage, (3) use of CT scan / surgical templates to relate tooth-to-bone relationship, (4) choosing appropriate implant shape to fit residual bone, and (5) appreciation of sinus anatomy post augmentation procedures. It was concluded that interactive CT scan software applications provide state-of-the-art diagnostic tools which create the confidence to benefit both patient and clinician in the quest for achieving predictable results.

Aesthetic Enhancement of Anterior Dental Implants with the Use of Tapered Osteotomes and Soft Tissue Manipulation
As osseointegration of endosseous dental implants has become predictable and well-documented, the emphasis in dental- implant treatment has shifted from functional concerns to the achievement of long-term aesthetic results. An adequate alveolar bone base is the prerequisite for functional and aesthetically optimal reconstruction of the soft-tissue architecture. This is true for both fixed partial denture (FPD) pontic sites and dental implant sites. In patients with sufficient bone height but insufficient bone…

Does residual cement around implant-supported restorations cause peri-implant disease? A retrospective case analysis
The purpose of this study was to determine the relationship between patients with a history of periodontitis and development of cement-related peri-implant disease. Seventy-seven patients with 129 implants for this retrospective analysis were selected from completed implant cases that were scheduled for regular maintenance or had experienced mechanical or biological complications between years 2006 and 2011 in private practice. Implants with extracoronal residual cement and implants without cement remnants were analyzed.

Immediate Dentoalveolar Restoration (IDR) - A New Technique for Compromised Extraction Sites
The Immediate Dentoalveolar Restoration (IDR) is a technique established to broaden indications for immediate loading on individual teeth even in compromised sites. This presentation outlines this new surgical/restorative protocol by describing it in step-by-step detail. Extraction site management, buccal bone reconstruction and soft tissue enhancement will be featured.

Tissue Engineering and Platelet Derived Growth Factors: Evidence Based Therapy
Platelet derived growth factors are now routinely utilized in reconstructive therapy. This presentation describes very detailed and evidence based guidelines for clinicians interested in enhancing their abilities in tissue engineering, especially as it relates to bone augmentation. Specifically, while successful bone augmentation requires the standard surgical parameters of space maintenance, low pressure on the grafts and tension-free flap closure, optimization of this goal requires management and enhancement of the local biological conditions with growth factors. Towards that end, platelet concentrates through the constant release of growth factors are able to promote and enhance new vascularization, provide plasma protein, normal lipidemia, as well as increased collagen and fibrin activity.

Alveolar Ridge Regenerative Strategies: Autogenous Bone vs BMP-2
This clinical based presentation will compare the use of autogenous bone vs BMP-2 for alveolar ridge reconstruction. The science, indications, advantages and disadvantages of each approach will be featured. Single tooth to full arch reconstruction cases will also be shown along with understanding the application of non-resorbable vs resorbable mesh barriers for alveolar ridge reconstruction.
