A new surgical management for oro-antral communication - The resorbable guided tissue regeneration membrane - Bone substitute sandwich technique

This paper describes a new technique for the closure of oro-antral fistula/communication, in which both hard tissue (bone) and soft tissue closure is achieved The sandwich technique utilizes a suitable bone grafting material sandwiched between two sheaths of Biogide((R)) (a resorbable membrane) for the hard tissue closure of oro-antral communication post traumatic exodontia. The bone grafting material utilized for this case was Bio-oss. The result obtained was excellent with regeneration of sufficient bony tissue to allow placement of an endosseous implant. This sandwich technique is a simple and excellent technique for the closure of oro-antral communication, especially when subsequent placement of endosseous implant is considered without the need of donor site surgery for bone grafting. The otorhinolaryngologists and oral and maxillofacial surgeons should-find this technique very useful in the closure of oro-antral fistulae.
