Guided bone regeneration around an immediate transmucosal implant for single tooth replacement: a case report

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.
