Panoramic radiograph of historic dental implants, taken 1978. There is archeological evidence that humans have attempted to replace missing teeth with root form implants for thousands of years. Remains from ancient China (dating 4000 years ago) have carved bamboo pegs, tapped into the bone, to replace lost teeth, and 2000-year-old remains from ...
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. [3]
Alveolar bone resorption is a common side effect of tooth removal (extraction) due to severe tooth decay, trauma, or infection that limits dental implant placement. Surgical bone augmentation is associated with limitations such as high cost, bone graft rejection or failure, pain, infection, and the addition of 6–12 months to the treatment ...
RAIs are custom made to perfectly fit the tooth socket of a specific patient immediately after tooth extraction. Therefore every implant is unique. As an optimised root-form it is much more than a simple 1:1 replica of a tooth. Since it exactly fills the gap left after the tooth is extracted, surgery is rarely needed.
After tooth extraction, the residual crest irregularities, undercuts or bone spicules should be removed, because they may result in an obstruction in placing a prosthetic restorative appliance. Recontouring can be made at the time of extraction or at a later time.

The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
In order to obtain permission from patient for extraction of tooth, the dentist should explain that other treatment options are available, what is involved in the dental extraction procedure, the potential risks of the procedure and the benefits of the procedure. [2] The process of gaining consent should be documented in clinical notes. [2]
