Survival of the Brånemark implant in partially edentulous jaws: a 10-year prospective multicenter study.

TLDR

A prospective multicenter study followed 127 partially edentulous patients (age 18–70, 57 % female) who received 461 Brånemark implants and 163 fixed partial prostheses (83 % posterior) over 10 years of follow‑up. After 10 years, implant survival was 90.2 % in the maxilla and 93.7 % in the mandible, 73 % of implants remained traceable, 63 % of original prostheses were still in use (86.5 % cumulative), continuous prosthesis function reached 94.3 %, marginal bone loss averaged 0.7 mm, mucosal health was good, and no severe complications were reported, confirming the system’s safety and predictability.

Abstract

A total of 127 partially edentulous patients, treated according to the Brånemark protocol, was followed for 10 years after completion of prosthetic treatment. The patients ranged in age from 18 to 70 years, and 57% were female. Four hundred sixty-one implants were placed in 56 maxillae and 71 mandibles. In 125 patients, 163 fixed partial prostheses were attached to the implants; 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 either as failed or in function, providing cumulative implant survival rates of 90.2% and 93.7% for the maxilla and mandible, respectively. Of the original fixed prostheses, 63% (cumulatively 86.5%) were still in use, whereas the level of continuous cumulative prosthesis function, including primary and remade restorations, was 94.3% at the end of the evaluation period. Marginal bone resorption at the implants was low (mean = 0.7 mm), and mucosal health was good. No severe complications apart from the above-mentioned implant and prosthetic failures were reported. The Brånemark Implant System is a safe and predictable method for restoring partially edentulous patients, as demonstrated by this 10-year follow-up investigation.
