抄録

We studied an osseointegrated two-step type implants made of titaniumaloy and coated with hydroxyapatite, kindly supplied by Kyoto Ceramics.A total of 45 implants were used clinically in 38 patients during the 3 years and 1 month from March 1989 to March 1992. The patients were followed up to 8 years. Three types of superstructures were seated on the implants, and the long-term clinical follow-up was performed. The following results were obtained.
1.Clinically, a good outcome was obtained with all implants, fitted with three types of superstructures.
2.In one patient fitted with an implant-connected, operator-removable type of super structure, bone resorption was seen at the mesial side of the fixture neck, but there has been no evidence of re-resorption up to now, and it has been uneventful since then. However, careful follow-up is considered necessary he reafter.
