Résumé

The extraction of single as well as multiple teeth induces a series of adaptative changes in the soft and hard tissues that results in an overall regress of the edentulous site(s). The prevention and treatment of alveolar ridge deformities aims preserving and reconstructing soft and hard tissues of the edentulous ridge in order to render better conditions at the site for the future prosthesis installation. Different surgical techniques have been proposed to prevent ridge collapse after tooth extraction or to reconstruct the lost anatomy prior to prosthesis installation. In general terms, in mild defects, soft tissue augmentation may be sufficient to repair the deformity. However, in more severe deformities a combined or staged approach may be more appropriate. This article reviews the dimensional changes after tooth extraction, types alveolar ridge deformities and various techniques for the prevention and treatment of alveolar ridge defects.
