Abstract

Objective: Oroantral communication is a common complication observed following the extraction of posterior maxillary teeth, often causing concern for both patients and general practitioners. Various methods are employed to close these communications. To identify a closure technique with minimal complications that is rapid and easily applicable by general practitioners, we evaluated the effectiveness of using calcium sulfate graft material mixed with platelet-rich fibrin, followed by clinical and radiographic assessment of closure success. Material and Methods: A moderate-sized oroantral communications resulting from recent tooth extractions was radiographed to confirm the size and dimensions of the communication. Subsequently, a 20 ml blood sample was collected from the patient and centrifuged to obtain two tubes containing platelet-rich fibrin. Using the first tube, a platelet-rich fibrin plug was formed, applied, and sutured at the site of the communication. Calcium sulfate graft material was then applied after being mixed with the platelet-rich fibrin clot from the second tube. The patient was followed up at intervals of: day one, day three, one week, two weeks, and six months. Results: We showed successful closure of oroantral communications in this case, with clinical and radiographic follow-up for 6 months post-procedure. Conclusion: Within the limitations of this study, it can be concluded that the technique of using calcium sulfate graft material with platelet-rich fibrin is a successful, cost-effective, and easily applicable method for managing moderate-sized oroantral communications.
