use of collagen implant [zenoderm] in the treatment of oro-antral communications and fistulae

Although several methods of surgical repair of oro-antral fistulae have been described, only few have received wide acceptance. The most commonly used methods of closure rely on the mobilization of soft tissue flaps and require a degree of surgical expertise that may not be available at the time of creation of an oro-antral communication. In this study, a collagen implant material [Zenoderm], in a thin sheet form was used for closure of OAC [eight cases] and OAF [two cases]. A simple surgical procedure was used. Closure was achieved successfully in all the cases involved in this study
