Histologic and radiographic bone density changes in alveolar socket preservation using autogenous bone graft and hyaluronic acid.

This study evaluates the success of immediate endosseous implants placed along with autogenous bone graft to fill the peri-implant gap. Thirty-two implants were inserted in 8 beagle dogs. The right and left lateral incisors in the maxilla and the mandible of all animals were extracted, and immediate postextraction implants were placed. In the control sites, no bone grafts or barrier membranes were used. In the contralateral experimental site, autogenous bone graft was used. The implants were retrieved with the jawbone for histomorphometric studies. The histomorphometric measurements were carried out using a computerized image analysis system. All implants were covered by compact, mature bone under examination in light microscopy. A high bone-implant contact percentage and bone density was observed at both grafted and nongrafted implant sites. The sites filled with autogenous bone graft showed a significantly higher crestal bone level and bone density compared to the nonfilled sites. The observations of the study emphasize that the filling of the peri-implant bone defects with autogenous bone grafts showed a better outcome compared to unfilled defects.

Bioactive Agents

A bone graft may be used in a variety of clinically practiced implant surgeries, namely, guided bone regeneration, extraction socket preservation or reconstruction, ridge augmentation, and sinus membrane elevation. The bone graft is of various types depending on the material, for instance, autogenous bone graft, allograft, xenograft, alloplastic graft, and autogenous bone graft with demineralized dentin matrix, which may be used alone or with other materials. Bioactive agents that promote bone formation, such as recombinant human bone morphogenetic protein-2 (rhBMP-2), have been shown to exhibit a clinically beneficial effect on bone regeneration. Here, we intend to present surgical guidelines for bone grafts and criteria for selection of bone graft materials by referring to evidence-based studies and recent lectures on the subject of ‘bone grafts for implant dentistry’ at the Amapá society of implantodontics, 2020.

Maxillary Tuberosity

The periodontal treatment of teeth with furcation defect is clinically challenging. In cases of class II furcation defects, the regenerative surgery shows low morbidity and good prognosis when correctly indicated. The aim of the presentstudy is to report a treatment option for class II furcation defect through autogenous bone graft associated with the Bichat’s fat pad. Case report: A 59-year-old female patient was diagnosed with class II furcation defect in the left mandibular first molar. The treatment comprised surgical reconstruction of the defect with a combination of maxillary tuberosity bone graft and Bichat’s fat pad. The clinical and radiographic follow-up of 180 days showed bone formation inthe furcation area and absence of probing depth. Conclusion: An association of autogenous graft form the maxillary tuberosity with a Bichat’s fat pad proved to be a safe, low cost, and effective therapy for the regenerative treatment of class II furcation.
