Reviewing the clinical evaluation reports on endosteal implants, there are not many,which evaluate the implants for a relatively long period and from objective viewpoints.
From 44 cases, to which alumina ceramic implants were applied in our department during the period from January 1982 to November 1990 and which are more than 5 years postoperative, 31 cases responding to recall were selected for the present study. Evaluation was made by the endosteal implant postoperative evaluation system in our department, and these cases were classified as Class 1 (good), Class 2 (fair), Class 3 (removal necessary), and Class 4 (removed).
The results were:13 cases in Class 1(41.9%), 9 cases in Class 2(29.0%), 2 cases in Class 3(6.5%), and 7 cases in Class 4 (22.6%). These results suggest that further modification is required for the alumina ceramic implant.
