Abstract :
Oroantral communication (OAC) is a pathological connection between the oral cavity and the maxillary sinus, commonly caused by various factors such as tooth extractions and pathology. Various techniques have been employed to address oroantral fistulae (OAF), predominantly focusing on soft tissue closure and neglecting the bony defect, which is crucial for prosthetic rehabilitation. This case report highlights a novel three-layered closure technique utilizing buccal fat pad (BFP), Guided Tissue Regeneration (GTR) membrane, and a sticky bone graft composed of autogenous and xenograft with i-Platelet Rich Fibrin (PRF), combined with buccal advancement flap and collagen membrane for OAF reconstruction. This innovative approach offers promising outcomes for OAF closure, enhancing patient outcomes and minimizing postoperative complications.
