Author(s): Noor Mohammed Al-Noori*
Abstract
Oroantral fistula is a pathological communication between oral cavity and maxillary antrum; commonly occurring after extraction of maxillary posterior teeth. Occasionally soft tissue closure is used in treatment of this defect but sometimes the soft tissue closure alone is not enough, so using of adjuvant material like Platelet Rich Fibrin is indicated. It is an autologous biomaterial; platelets and leukocytes of the blood in a strong natural fibrin matrix construct a complex structural design with excellent healing index. In this case report: after flap retraction and removing of the fistulas epithelial ling, Platelet rich fibrin used with soft tissue closure, then the follow up after 7-10-30 days show closure of the defect and cessation of symptoms after 10 days.
