Replacement of vertically root-fractured endodontically treated teeth with immediate implants in conjunction with a synthetic bone cement

PURPOSE: The purpose of this prospective study was to evaluate the clinical outcome of implants immediately placed into fresh extraction sockets for the replacement of endodontically treated teeth with signs of vertical root fracture. MATERIAL: Sixteen partially edentulous patients, with 1 tooth scheduled for extraction and showing clinical signs and symptoms and/or radiological evidence of vertical root fracture, were included in the study. Sixteen transmucosal implants were installed immediately after extraction and careful debridement. The gap between the implant surface and the socket walls was filled using synthetic bone grafting cement. Prosthetic phase occurred 3 to 4 months after surgery. Implant success and survival and radiographic bone loss were evaluated after 1 year of function. Patient satisfaction for mastication function, phonetics, and aesthetics was also assessed by means of a questionnaire. RESULTS: No implant failure occurred. The overall implant success and survival was 100% at 1 year. The mean follow-up was 13.5 months. All prostheses were successful. Periimplant bone loss after 1 year averaged 0.48 ± 0.20 mm. All patients reported full satisfaction for mastication function, phonetics, and aesthetics. CONCLUSIONS: The use of a synthetic bone grafting cement in combination with immediate implant placement procedure can be considered a safe, effective, and predictable treatment option for the rehabilitation of fresh postextraction sockets.
