6. Dehydrated Human Amnion-Chorion Barrier used to Assist Mucogingival Coverage of Titanium Mesh and rhBMP-2 Augmentation of Severe Maxillary Alveolar Ridge Defect: A Case Report

Recombinant human bone morphogenetic protein (rhBMP-2) is a potent osteoinductive protein that has proven to be a valuable tool for augmentation of severe alveolar dental defects. Because rhBMP-2 must be combined with a collagen carrier, it lacks space maintenance and must therefore be combined with ridged materials such as Titanium mesh. While effective for space maintenance and a proven aid in bone augmentation procedures, Titanium mesh has a documented history of premature exposure which can reduce final outcome gains.  The current Case Report documents use of an amnion-chorion barrier to assist mucogingival coverage of a Titanium mesh barrier and rh- BMP2 augmentation of a severely atrophic anterior maxillary ridge.

18. Long-Term Retrospective Clinical and Radiographic Follow-up Evaluation of 108 OsteoCare™ Mini and Midi Ball-Type Implants Subjected to Immediate Loading of Mandibular Overdentures

Dental implants have provided major changes in the treatment planning of completely edentulous patients with atrophic ridges Objectives: the present contemplate retrospectively evaluated OsteoCare™ Mini and Midi one-piece ball-type dental implants for immediate loading of mandibular overdentures with an emphasis on long-term survival, implant stability, peri-implant soft and hard tissue conditions, and patient satisfaction.  Follow-up averaged 5.4 years (range between 5-11 years) and the cumulative survival rate (CSR) was 100%.  OsteoCare™ Mini and Midi one-piece ball-type implants have demonstrated excellent long-term survival, marginal bone response, and soft tissue conditions with immediately loaded mandibular overdentures.

30. Long-Term Efficacy of Occlusal Loading on an Implant with Low Stability: A Case Report

Primary stability plays an important role in successful osseointegration. Primary stability is defined as the contact of implant and bone during the surgical implant placement. This contact is crucial for direct bone deposition between the bone/implant interface as well as subsequent mineralization process of osteogenesis. Secondary stability, however, is not purely a mechanical stability of the implant, unlike the primary stability; it is a biological stability which is formed within few weeks after implant placement during bone remodeling. This case report demonstrates that the secondary stability can be controlled by progressive loading and it dictates the percentage of functionally and biologically integrated bone-implant contact which in turn dictates its loading schedule.

36. A Modified Split-Crest Technique using Piezoelectric Surgery and Immediate Implant Placement in the Atrophic Maxilla

The successful placement of dental implants is limited by the presence of a deficient maxillary alveolar ridge. This study reports a modified approach to the split-crest technique using piezoelectric surgery in combination with immediate implant placement in management of atrophic maxillary ridges.  Results achieved showed a significant increase in the mean maxillary ridge width by 2.93 ± 0.13 mm. The survival rate of the implants was 100%.
