Brief Summary

Following tooth extraction alveolar ridge will undergo dimensional changes and soft tissue may collapse. These changes may complicate the subsequent restorative procedure especially in the esthetic zone.

It was observed that socket-healing process may be divided into three sequential, and frequently over-lapping phases: inflammatory, proliferative and modeling/remodeling.

Implants placed in fresh extraction sockets alone wasn't found to prevent the resorption of the alveolar bone.

Detailed Description

Alveolar socket preservation using primary flap closure technique utilizing free gingival graft in conjunction with bone substitutes didn't produce the desired effect on ridge preservation compared with bone substitutes alone. A clinical trial showed that achieving primary closure didn't present additional beneficial effect on preserving ridge width, however, the mucosa was significantly thicker and more coronally positioned.

Also soft tissue graft has its limitations on covering graft material and socket preservation due to the higher morbidity given that the soft tissue graft has to be harvested from a donor site of the patient.

Another options for socket seal are coronal advancement of buccal flap or rotating grafts from tissue adjacent to cover the defect but they have limitations such as altering the mucogingival line and creating a shallow vestibule.

Lekovic et al. investigated the use of a non-resorbable polytetrafluroethylene membrane but it was found also to have its limitations as 30% of the membranes became exposed and as a result loss of bone height and width occurred.

Also studies have found that using bone substitutes together with collagen membrane with primary closure of the socket has shown clear effects on preserving alveolar ridge height as well as ridge width, however, its limitation are flap dehiscence and subsequent membrane exposure and the increased cost.
