Survival of the Branemark implant in partially edentulous jaws: A 10-year prospective multicenter study

A total of 127 partially edentulous patients, treated according to the Bran emark protocol, was followed for 10 years after completion of prosthetic tr eatment. The patients ranged in age from 18 to 70 years, and 57% were femal e. Four hundred sixty-one implants were placed in 56 maxillae and 71 mandib les. In 125 patients, 163 fixed partial prostheses were attached to the imp lants; a majority of the prostheses (83%) were located in posterior regions . At the end of the 10-year period, 73% of the implants could be traced eit her as failed or in function, providing cumulative implant survival rates o f 90.2% and 93.7% for the maxilla and mandible, respectively. Of the origin al fixed prostheses, 63% (cumulatively 86.5%) were still in use, whereas th e level of continuous cumulative prosthesis function, including primary and remade restorations, was 94.3% at the end of the evaluation period. Margin al bone resorption at the implants was low (mean = 0.7 mm), and mucosal hea lth was good. No severe complications apart from the above-mentioned implan t and prosthetic failures were reported. The Branemark Implant System is a safe and predictable method for restoring partially edentulous patients, as demonstrated by this 10-year follow-up investigation.
