The Successful Application of Osseointegrated Implants to the Posterior Jaw: A Long-term Retrospective Study
Nevins, Myron / Langer, Burton
This long-term study has demonstrated the successful use of osseointegrated implants to replace posterior teeth in the partially dentate patient. A total of 1,203 Nobelpharma implants placed by two periodontists practicing in traditional office settings were included in the survey. Of the 551 implants placed in the mandible, 25 failed, for a success rate of 95.5%. Of the 247 mandibular prostheses fabricated for 200 mandibles, 8 failed, for a prosthesis stability rate exceeding 97%. Of the 652 implants placed in the maxilla, 31 failed, for a success rate of 95.2%. Of the 250 maxillary prostheses fabricated for 193 maxillae, 2 failed, for a success rate exceeding 99%. The results compare favorably to previous reports in terms of implant survival and stability.
