Abstract OACs are not unusual complications in oral and maxillofacial surgery. Extraction of maxillary posterior teeth is the most common cause. Numerous surgical techniques have been described for treatment of OACs. However most of these techniques depend on soft tissue closure only without grafting the bony defect of the OAC Objectives: The aim of this study is to evaluate oroantral communication repair using one bone substitute (Fisiograft) and platelets rich fibrin Patients and methods: In the present study, eight patients complaining from OAC following extraction of maxillary posterior tooth were selected. The bony defect of the OAC was grafted with Fisiograft sandwiched between two PRF membranes. Then the graft was covered by buccal advancement flap. The patients were followed up clinically after 1, 2, 4 and 12 weeks postoperatively. Radiographic evaluation was performed immediately and after twelve weeks postoperatively. |
