From 1989 to 1994, using the Osseointegrated Implant System, a total of 262 fixtures were implanted in 65 patients.
For 5 years, the cumulative survival rate of implants was 92.1%.
4 cases of overdentures and 66 cases of bridge type for a total of 70 superstructures were fitted to the implants in the maxilla and mandible.
During the observation period, clinical structural problems, that is, broken artificial teeth 8, fractured gold screw 2 and fractured abutment screw 1 in the superstructures occurred in 11 cases. Other clinically functional problems occurred in 3 cases,that is, trouble of pronunciation 1, aesthetic problem 1, and difficult situation of implants cleaning 1. In this report I studied the problems of the design and manufacture, the point of contact during pronunciation, aesthetics, and condition of implant maintenance.
