Abstract
The purpose of this study was to evaluate the use of autogenous gingival grafts as barriers for endosseous implants placed directly into fresh extraction sockets. This study consisted of four patients who presented with hopeless teeth due to endodontic pathology, caries, or root resorption. In all cases, the teeth in question were extracted at the Stage 1 surgery. An endosseous root form implant was immediately placed into the extraction socket in each case. As a consequence of immediate placement, there was a lack of primary closure over the fixture and a large space was present between the fixture and the remaining alveolus. An autogenous gingival graft was sutured in place to cover the fixture and act as a physical barrier to epithelium, food debris, and possibly bacteria. At the Stage 2 surgery, all implants achieved complete osseointegration clinically and radiographically. The results at 16 to 24 months reveal continued success in all four cases. This report demonstrates the potential of autogenous gingival grafts in immediate implant placement. A clinical trial to fully assess the potential of this procedure is recommended.
