Alveolar Ridge Preservation Using Beta Tricalcium Phosphate -A Review

Abstract

Materials and Methods:

 Patients requiring tooth extraction except the third molars and who agreed for bone grafting were selected for the study. Randomly these were divided into two groups, one was the socket preservation group in which after extraction, bone graft  is placed in the extraction socket and protected with a collagen membrane and the other was a control group wherein no graft was placed and extraction socket was left to heal normally. Radiographic height and width is assessed, at time of extraction and 6 month postoperatively using vista scan and bone calliper.

Conclusion:

β - TCP placed at the time of grafting extraction socket was well tolerated in all sites with barrier membrane used. There was no incidence of graft rejection or infection  .Guided Bone regeneration is a successful method of alveolar ridge preservation and that synthetic bone substitute (β- TCP) with a collagen membrane can be usefully utilized for this purpose
