A major goal in dentistry and periodontal treatment is to maintain teeth in good condition for good function in health and aesthetics. However, as a result of caries, periodontal disease and traumatic injuries, a tooth extraction sometimes, is inevitable.

Following the extraction, the alveolar ridge, will experience a change in its topography. This alterations in the alveolar process may lead to difficulties at the time of implant placement or functional and aesthetic difficulties with any prosthesis designed to replace the missing tooth.

Clearly, all good alternatives made for a missing tooth, do not give an answer to the biological and dimensional changes that occur after tooth extraction if this issue is not approached during extraction or after healing.

When the PDL is gone, blood supply to the bone reduces and during healing and remodeling, resorbtion takes place. Several ways were offered throughout the years to deal with this issue trying to preserve the alveolar ridge dimensions or minimize the expected changes after extraction.

Extraction and immediate implant placement will not provide the answer on one hand and leaving the socket to heal naturally on the other hand, also is not a predictable solution.

The presentation will discuss the need to plan the treatment before extraction in order limit post extraction alteration, promote supportive healing of the extraction ridge area to prepare the site for the restorative phase either with an implant supported crown or other prosthetic options.

Special attention will be given to the issue of socket preservation during extraction and measures to correct ridge deficiencies after healing for restorative purposes.
