Maxillary implant-retained partial overdenture with Dolder bar attachment: a clinical report.

This article describes a technique for maintaining a maxillary Kennedy III partial removable dental prosthesis design in a patient who had non-restorable failing abutments by replacing the abutments with dental implants. Two implants were placed immediately after extraction of the abutment teeth in the anterior maxilla. After the implants were fully integrated, a Dolder bar attachment was fitted onto the implants.

A new tunnel technique with acellular dermal matrix for soft tissue preparation prior to symphyseal block graft--a description of technique and case report.

The aim of this report was to describe a newly designed tunnel technique (A New Tunnel Technique) using acellular dermal matrix (ADM) allograft for soft tissue augmentation prior to mono-cortical block graft. Two cases with vertical and horizontal ridge deficiency in the mandibular anterior area were indicated for mono-cortical block grafting before implant placement. Soft tissue evaluation and measurements showed thin tissue covering the defect area composed mainly of nonkeratinized alveolar mucosa measuring 1 to 2 mm in most of the sites.

Implant success rate in dental school setting: retrospective study.

Implant dentistry is a successful way to replace missing teeth. The purpose of this study was to retrospectively assess the rate of implant survival in a graduate clinic and to relate the findings to the health of patients. The charts of 133 patients who received implants at the School of Dental Medicine at the University at Buffalo were randomly selected and reviewed.

A comparative analysis of bone formation induced by human demineralized freeze-dried bone and enamel matrix derivative in rat calvaria critical-size bone defects.

Background: Human demineralized freeze-dried bone allograft (DFDBA) and enamel matrix derivative (EMD) have been used with varying success for the treatment of bone and periodontal defects. The purpose of this study was to compare qualitatively and quantitatively the bone formation induced by DFDBA and EMD to that of a positive control, recombinant human bone morphogenetic protein 2 (rhBMP-2), in the 8-mm rat calvaria critical-size bone defect.

Methods: Five groups of five rats each were used.

Calcium sulfate and platelet-rich plasma make a novel osteoinductive biomaterial for bone regeneration.

Background: With the present study we introduce a novel and simple biomaterial able to induce regeneration of bone. We theorized that nourishing a bone defect with calcium and with a large amount of activated platelets may initiate a series of biological processes that culminate in bone regeneration. Thus, we engineered CS-Platelet, a biomaterial based on the combination of Calcium Sulfate and Platelet-Rich Plasma in which Calcium Sulfate also acts as an activator of the platelets, therefore avoiding the need to activate the platelets with an agonist.

Using transitional implants as fixation screws to stabilize a surgical template for accurate implant placement: a clinical report.

This article describes a method of using transitional implants as surgical fixation screws to orient a surgical template predictably during the placement of implants in the anterior mandible for an implant-supported bar-retained overdenture. Ridge reduction, transitional implant placement, implant placement, and removal of the transitional implants were completed in a single surgical appointment. Details of the template fabrication, incorporating transitional implants and surgical techniques, are described.

Intraosseous sarcoidosis of the jaws mimicking aggressive periodontitis: a case report and literature review.

Background: Sarcoidosis is a relatively common systemic granulomatous disease of unknown etiology. The skeletal system is affected in up to 39% of patients, but intraosseous sarcoidosis affecting the maxilla and mandible is rare. Only 20 cases have been reported previously in the English literature.
