These lead to changes in the alveolar process in a 3 dimensional fashion causing hard and soft tissue deficiency which may affect the ability to restore the site. Preservation of the alveolar crest after tooth extraction is essential to maintain the vertical and horizontal dimensions of the alveolar ridge. Several techniques and materials have been introduced to minimize crestal bone loss. There is a broad consensus that ridge preservation procedures are efficient in limiting the post extraction dimensional loss of the ridge. However, the key to successful outcome is proper treatment planning according to the case and prognosis. Conclusion: The aim of this literature review is to discuss the several bone preservation techniques and materials to minimize post-extraction loss of hard and soft tissues. Keywords: Alveolar ridge; bone loss; bone preservation; implant; post extraction socket. Mini-review Article
