Implant and prosthesis success for 77 partially edentulous patients, provided with 97 fixed prostheses, supported by 230 Brånemark implants, in place for up to 12 years (mean 5.41 years), were documented in this study. Implant losses per location mirrored their placement, with no difference between zones I and II or between the maxilla and mandible. The implant success rate was 94%, and continuous prosthesis stability was 97%. These results indicate that the Brånemark implant-supported fixed partial prosthesis is a highly efficacious treatment.
