Seven patients were reconstructed their occlusion with osseointegrated implant (Branemark System) in Department of Oral Surgery, Nagoya University Hospital. Three cases of patients have been analysed for their mandibular bone quality with Digital Image Processing (DIP) method preoperatively. Results obtained were as follows : 1. Seven patients who had an extreme difficulty in wearing conventional removal dentures were treated in this study. The subjects consisted of 3 rnales ;tnd 4 females, and their ages ranged from 46 to 66 years. The lesion was an edentulous mandible in 3 cases, an edentulous maxilla in one case and partially edentulous in 3 cases. 2. Twenty one fixtures in maxilla and 23 fixtures in manclible, totally 44 fixtures were installed in 7 cases. One fixture in mandible and one in maxilla failed to osseointegrate, giving the fixture survival rate of 95.2% in mandible and 95.7% in maxilla. 3. Three edentulous mandibular patients received the bone duality analysis (DIP method) using occlusal film rreoreratively. Results of bone density were 2.98, 1.98, 3,10 Al mm in each case. Case 2 who had the lowest bone density failed one fixture to osseointegrate. 4. DIP method was very useful as a bone quality measuring method. Because it could be easily carried out to analyse the jaw bone quality for dental implant without any variation of film conditions.
