11. Mandibular Reconstruction and Oral Rehabilitation with Dental Implants by Sequel of Ossifying Fibroma with 8 Years of Evolution: A Clinical Report
Ossifying fibroma (osteogenic fibroma, Cemento-ossifying fibroma) is a true neoplasm with significant growth potential. When the lesion obtains a relevant scale, results in a substantial osteolytic reaction, being essential surgical resection followed by bone grafting for functional reconstruction. The mandibular reconstruction in the head and neck surgery has been a topic discussed throughout history, especially in the last 50 years. The use of iliac crest grafts followed by osseointegrated dental implants provides a valuable technique for the oral rehabilitation
in patients with this type of defects.
33. Dentin Autografts Maintain Alveolar Width Following Tooth Extraction
The aim of this study was to preserve alveolus by maintaining natural PDL with a buccal dentin autograft. In the dog study, new cementum was found over both the cut and preexisting
dentin. No inflammation was noted. Half of the human’s models dentin autografts showed less resorption. One patient had equal resorption. Two slivers sloughed. In the second human study, all sites showed excellent healing. New periodontal ligament formed with new cementum over all autografts.
45. Complex Full arch Implant Impressions Simplified: A Clinical Tip for Accurate Predictable Impressions
Treating full arch multiple implant supported complex cases is clinically and technically challenging. To obtain precise and accurate impressions is critical to minimize the laboratory errors and prevent prosthesis misfit. Splinting of implant impression copings has been recommended when fabricating prostheses supported by multiple implants.
51. Regeneration of the Deficient Alveolar Ridge with Utilization of “Tunnel Approach” to Guided Bone Regeneration. A Retrospective Study of the Outcomes
A number of clinical factors like trauma, past surgical procedures and various pathologic conditions cause substantial alteration of normal bone structure requiring osteoregenerative procedures to restore an adequate volume and architecture of alveolar structure needed for implant placement. The objective of this retrospective study was to analyze clinical benefits gained by a completion of guided osseous tissue regeneration treatment with the utilization of a “tunnel approach.”
