The resorption of alveolar bone following tooth extraction may present a significant problem in implant and restorative dentistry. Ridge preservation is the procedures undertaken at the time of tooth removal that is designed to minimize ridge resorption and maximize bone formation within the socket. Many procedures have been suggested including minimally traumatic tooth extraction, soft or hard tissue grafting, as well as concomitant use of barrier membrane and osseous grafts. This paper discusses the healing process of extraction socket and compares the clinical results of various ridge preserving techniques. With a careful patient evaluation, the ridge dimension and configuration can be effectively maintained using the ridge preservation procedure.
