At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Barrier membranes have been derived from a variety of sources, both natural and synthetic, and are marketed under various trade names. Membranes used in guided bone regeneration (GBR) and grafting may be of two principal varieties: non-resorbable; resorbable.
The most frequently used is called guided bone graft augmentation where a defect is filled with either natural (harvested or autograft) bone or allograft (donor bone or synthetic bone substitute), covered with a semi-permeable membrane and allowed to heal. During the healing phase, natural bone replaces the graft, forming a new bony base for ...
Others, including Broome and Taggert [4] and Donn [5] also described the use of SECT grafts for increasing the zone of keratinized tissue. Of the various ways of preparing the graft recipient site, Edel described using two vertical incisions, mesial and distal to the teeth at which the zone of keratinized tissue was intended to be widened.

Many surgical approaches are used in the treatment of advanced periodontitis, including open flap debridement and osseous surgery, as well as guided tissue regeneration and bone grafting. The goal of periodontal surgery is access for definitive calculus removal and surgical management of bony irregularities which have resulted from the disease ...
Guided bone reconstruction is a technique in which bone growth is enhanced by preventing soft tissue ingrowth into the desired area and utilizes either resorbable or nonresorbable membranes. [22] Metallic membranes [23] or membranes supported by a titanium frame [24] [25] [26] have been tested and have been successful. The acellular dermal ...
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.
