Strategies for management of single-tooth extraction sites in aesthetic implant therapy.

Achieving predictable aesthetic outcomes following the planned removal of a natural tooth suffering from structural, endodontic, or periodontal compromise depends on a multitude of factors that, once identified, guide the implant team in selecting the surgical and prosthetic treatment options best suited for the individual clinical scenario. This article presents pertinent information regarding systematic patient evaluation and special treatment planning considerations for patients facing the loss of a single tooth in an area of high aesthetic importance. The rationale for and details of performing the Bio-Col site preservation technique at the time of tooth removal; guidelines for immediate versus delayed implant placement; selection and sequencing of site-development procedures according to the types of alveolar ridge defects encountered following tooth removal despite the use of site preservation; and a description of prosthetic techniques necessary for the successful management of single-tooth extraction sites in areas of aesthetic concern also are reviewed.
