Al2O3 Implants (Bioceram®) which were installed more than 10 years ago in our clinic, were studied. The number of cases and implants were 75 and 106 respectively. First, the survival and removal rate thereof were checked. A questionnaire was given to the patients in order to find out how satisfied they were with the implants and whether they could masticate well or not. The implants were classified and evaluated by radiographic examination.
As a result, the age of the patients widely ranged from 19 to 69 years. The implant sites were concentrated in the mandibular molar area. 80.2% of examined cases could be followed up, and the 10-year survival rate was 85.9%. Within 4 years, there were no removed implants, however, after 4 years, some implants were removed mostly due to periimplantitis. More than 85% of the patients were satisfied with implants, and 80% of the patients masticated well. By radiographic examination, T-type Bioceram® implant was considered to be the most stable type. The results of this study suggested that the key to long-term success of the implant was to have regular checkups.
