Prognoses were surveyed in 36 patients who underwent insertion of osseointegrated implants (Brånemark system) from January 1988 to September 1992.<BR>One-hundred and forty-one fixtures were inserted in the mandibula, 66 in the maxilla, and 12 flange fixtures were inserted in the orbital or temporal region. The 1-year success rate of osseointegration was 98.2%, the 2-year rate was 97.5%, and after 3-years osseointegration was not lost in any case. In 3 cases, osseointegration was not obtained. Two of these 3 cases underwent radiation therapy before fixture insertion, and in the other an onlay bone graft was performed concurrently with fixture insertion in the maxilla. These results indicate that this implant system is very reliable in routine cases. However, irradiated patients and patients who have received bone transplants pose problems. Further studies are required to solve these problems.
