Abstract

Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. Guided bone regeneration techniques and the use of bone replacement materials have both been shown to enhance socket healing and to potentially modify the resorption process. This article will describe a surgical technique using textured, high-density polytetrafluoroethylene (PTFE) membrane and particulate bone replacement materials for graft containment and prevention of soft tissue ingrowth into healing extraction sites. The technique described does not require primary closure, facilitating the preservation of keratinized mucosa and gingival architecture.
