Abstract

In Japan, the clinical application of HA-coated implants began in 1992 after approval by the Ministry of Health and Welfare, 7 years lafer than in the United States. In this study, 420 Integral implants were placed in 98 patients (45 males and 53 females) aged 19 to 67 years at the Medical and Dental Clinic of the Health Sciences University of Hokkaido. There were 134 implants (31.9%) placed in the maxilla and 286 implants (68.1%) in the mandible. Of the 420 implants placed, all had good osseointegration at the time of second surgery, and 6 failed during the follow-up period between 1 to 60 months after restoration. The implants that failed were shorter than 10mm and no significant difference could be found between maxillary and mandibular failure rates.<BR>According to life-table survival, the overall cumulative survival rate at 5 years was 96.98%. The amount of the hone loss measured on panoramic X-ray photos was less than 1.1mm for 5 years.<BR>The clinical results indicate that the Integral HA-coated implant is effective in long-term treatment of patients regardless of the location of the implant.
