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.

The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge, or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic or crown.
Improved Patient Convenience: Patients receive new teeth immediately following surgery, resulting in shorter recovery times and decreased risk of complications. Preservation of Bone: The use of minimal implants and multi-unit abutments reduces the necessity for bone augmentation procedures such as sinus lifts, facilitating efficient and rapid ...
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.

Technique depicted in 3D video This image shows how Nobel Biocare's All-on-4 solution works. The term All-on-4, also known as All-on-Four [1] and All-in-Four, [2] refers to 'all' teeth being supported 'on four' dental implants, a prosthodontics procedure [3] [4] for total rehabilitation of the edentulous (toothless) patient, or for patients with badly broken down teeth, decayed teeth, or ...
Synthetic jaw implants already on the market prior to the 1976 Federal law requiring medical devices be proven safe and effective were exempt and continued to be sold after 1976 without proof of safety. Teflon implants made by Vitek, and silicone ones made by Dow Corning, raised the most concern.
The recovery time after the surgery depends on the extent of the surgery itself. Patients are usually advised to eat soft foods for days, or sometimes weeks, to allow their jaw time to heal. They also require regular checkups with the doctor to monitor bone displacement, signs of infection, or other issues. [1]
Jaw surgery may be required to fix severe malocclusions. [41] The bone is broken during surgery and stabilized with titanium (or bioresorbable) plates and screws to allow for healing to take place. [42] After surgery, regular orthodontic treatment is used to move the teeth into their final position. [43]
