Managing Ridge Resorption After Tooth Extraction Using Partial Extraction Therapy.

Achieving successful long-term esthetic outcomes in implant dentistry requires that the height and width of the facial or buccal alveolar bone wall and, subsequently, the peri-implant tissues be maintained. Partial extraction therapy (PET) can be used to reduce the risk of facio-lingual collapse after tooth loss and improve the preservation of alveolar bone height and blood supply. This article demonstrates the use of PET for treatment of a hopeless tooth in the esthetic zone. After removal of the fractured maxillary central incisor, an implant was placed and restored with excellent esthetic, functional, and periodontal results.
