Three mandibular edentulous patients treated with osseointegrated implants were reported. They were treated in the department of Oral Surgery, Nagoya University Hospital and followed for three years. In this paper the relationship between bone quality and degree of bone resorption around the fixtures was analysed.<BR>Results were summarized as follows:<BR>1. The cases were one male and two female and aged 66, 64 and 50 years old.<BR>2. The bone qualities of each case were analysed by DIP method preoperatively. The bone densities were 2.98, 1.98 and 3.10.<SUB></SUB>3. Six fixtures were installed in each case and one fixture of case 2 failed to osseointegrate. Final survival rate of the fixtures was 95%.<BR>4. The degree of bone resorption in the low DIP case was greater than that in the high DIP case.<BR>5. The degree of bone resorption were almost equal in any site of mandible.<BR>6. The degree of bone resorption in high Plaque Index case was greater than that in the low Plaque Index case.
