Achieving anterior aesthetics with an anti-rotational abutment

Single-tooth implants of various minerals and metals have been used, with some success, since ancient times. However, single-tooth implant survival was unpredictable until Branemark and his co-workers developed the theory and technique for obtaining a predictable direct bone to implant interface, which has been termed "osseointegration." Retrospective studies suggest excellent survival of single-tooth implants that predictably achieve this direct bone to implant interface. Case reports of single-tooth implants in the anterior and posterior areas of the jaws suggest the efficacy of this treatment, although scientific prospective studies evaluating the safety and efficacy of this treatment have only recently begun.
