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.

Because of the sturdy anchorage achievable in the dense bone of the zygomatic region, and the wide stress distribution achieved on these tilted implants, a prosthesis can often be immediately placed at the time of surgery. [6] The zygoma implant is available in lengths ranging from 30 to 52.5 mm.
Dental implant, 3D illustration. A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor.
In the late 1970s advancement of the lower jaw (mandibular advancement) was noted to improve sleepiness in three patients. Subsequently, maxillomandibular advancement was used for patients with obstructive sleep apnea. Currently, maxillomandibular advancement surgery is often performed simultaneously with genioglossus advancement (tongue ...
Use of barrier membranes to direct bone regeneration was first described in the context of orthopaedic research 1959. [2] The theoretical principles basic to guided tissue regeneration were developed by Melcher in 1976, who outlined the necessity of excluding unwanted cell lines from healing sites to allow growth of desired tissues.

After extraction of a tooth, the clot in the alveolus fills in with immature bone, which later is remodeled into mature secondary bone. Disturbance of the blood clot can cause alveolar osteitis, commonly referred to as "dry socket". With the partial or total loss of teeth, the alveolar process undergoes resorption.
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
Fractured teeth. Teeth in the fracture line of the jaw bone; Teeth which cannot be restored endodontically. [10] [11] Prosthetics; teeth detrimental to the fit or appearance of dentures. [12] Head and neck radiation therapy, to treat and/or manage tumors, may require extraction of teeth, either before or after radiation treatments.
