Alveolar Ridge Preservation: A Review

Abstract

A number of changes occur in the alveolar ridge following tooth extraction such as remodeling of bone in the alveolar ridge that can lead to loss of alveolar ridge width and height. Studies have shown that most of the changes occur in the first three months following teeth extraction. The goal of alveolar ridge preservation procedures is to maintain the dimensions of the extraction site, reduce significant loss of alveolar ridge and height and maintain adequate bone for dental implant placement. Alveolar ridge preservation also helps prevent the need for additional procedures prior to dental implants such as utilization of block grafting for ridge augmentation and sinus augmentation. It is indicated for both intact extraction sockets and extraction sites with significant damage to its walls. The goal of this article is to present two case reports on patient management for extraction sockets with damaged boney walls using Alveolar ridge preservation.
