Socket and Ridge Preservation

Socket preservation or alveolar ridge preservation is a procedure done to reduce bone loss after the extraction of a tooth.  A bone graft is placed into the socket at the time of extraction.  Sometimes the socket requires the placement of a membrane to protect the bone graft.  Without socket preservation the bone quickly resorbs and 60% of the bone volume can be lost six months after the tooth extraction.  Preserving the bone allows the placement of an implant or a bridge with natural looking crowns.


Ridge Augmentation differs from ridge preservation in that ridge preservation requires that the bone graft be placed inside a socket after the extraction whereas ridge augmentation is bone grafting done after the ridge has resorbed.  Ridge augmentation is necessary to create ridge height and width before implant therapy or placement of a fixed bridge.
