This case report describes the procedure of guided bone regeneration around an endosseous dental implant, placed into an extraction alveolus in the absence of total soft tissue coverage, ie, in a transmucosal condition. The technique presented permits an immediate placement of the implant after the extraction of the maxillary right lateral incisor. A nonresorbable barrier membrane was used, and strict chemical plaque control was maintained during osseointegration. After an uneventful healing period of 6 months, the membrane was removed in a second-stage surgery. Two months later, the fixed single tooth prosthesis was placed. The learning objective of this article is to explain the immediate transmucosal implant surgery technique, using a case report to illustrate the procedure.
