A bone graft is a procedure to replace missing jaw bone. Both maxillary (upper jaw) and mandibular (lower jaw) bone can be replaced.
When a tooth is extracted or there is severe periodontal disease, the bone of the jaw resorbs in that area. Teeth in the mouth can become loose due to bone loss, as the bone begins to lack the support it needs to hold the tooth in place. Bone loss can also prevent the placement of implants and cause cosmetic defects in finished bridges and implants. Bone loss can be treated with a bone graft to rebuild bone structures in the desired area. In the procedure, a biocompatible material is placed under the gums and onto the already existing bone. Over time, the grafting material allows for the deposition of new bone cells in the area, allowing the bone to be built back up. Once the graft has been fully integrated, the bone will be healthy and strong enough to support any teeth or dental implants.
