Osseointegrated implant bridges (OIB) have shown excellent results in the majority of cases. Since 1983, 1,022 fixtures has been applied to 241 superstructures in Tokyo Dental College Hospital. The aim of present study was to examine their functioning survival rate during recent ten years. The functioning survival rate of the superstructure of OIB has been almost 100% in both maxilla and mandible. Although 13.0% of these fixtures had to be removed in maxillary complete cases, only 3.3% of fixtures were removed in other cases. In maxillary complete cases, the functioning survival rate of OIB fixtures gradually decreases from 91% to 74% (91%, less than 3 years; 84%, between 3 and 7 years; 74%, more than 7 years), but it remained at about 97% for all periods in other cases. Apparently, the functioning survival rate of OIB fixture is generally determined within the period of one year, so almost the same rate is maintained thereafter. It is suggested that if more fixture numbers in the superstructure were applied to maxillary complete cases, the functional survival rate might improve.
