Abstract

Endosseous implants are the treatment of choice for restoring function and reconstructing edentulous areas of the maxilla and mandible. Alveolar defects can be reconstructed by either distraction osteogenesis or autogenous bone grafting. After alveolar reconstruction, endosseous implants are used to support and retain the prosthesis for restoration of form and function. We retrospectively analyzed the success rates of endosseous implant placement in distracted versus autogenous bone graft reconstruction sites in our patient population at Loma Linda University Medical Center, Department of Oral and Maxillofacial Surgery. 82 consecutive patients requiring alveolar augmentation prior to implant placement were evaluated. All patients were given treatment options for reconstructing their alveolar defects, which included autogenous bone grafting versus distraction osteogenesis. 65 patients received autogenous grafts (anterior iliac crest--44, retromolar--17, tibia--2, chin--2) and 17 patients underwent distraction osteogenesis prior to implant placement. The donor site for autogenous harvesting was determined by the volume of bone needed at the recipient site. A total of 184 implants were placed in the autogenous bone-grafted sites and 56 implants in the distracted bone sites. Implants placed in sites restored with autogenous bone grafts had an implant success rate of 97% (178/184); whereas implants placed in distracted bone sites had a success rate of 98% (55/56). In the autogenous grafted group, 3 implants failed in the posterior mandible, one in the anterior maxilla, one in the anterior mandible, and one in the posterior maxilla. In the distraction group, one implant failed in the posterior mandible.
