This study aims to applicate the Biometric impression trays for Japanese edentulous patients. A hundred (fifity males and fifity females) Japanese bucco-lingual breadth (BLB) s of the dentulous alveolar process were measured on maxillary study casts by the three dimensional coordinate measuring machine.Results:1. Average measurements (mm) and standard deviations (mm) were as follows. Central incisor; 5.7±1.15, canine 7.5±1.41, first premolar 10.7±1.07, second premolar 11.4±1.37, first molar 13.4±1.25 and second molar 12.3±1.33.2. Japanese average measurements were 0.5-1.0mm smaller in incisor and canine region, but 0.6-0.8 larger in premolar and molar region as compared with figures of Scottish that Watt had reported.3. Biometric tray of which design is based on the average BLB measurements will become a concrete guide to the breadth of the flange of complete upper dentures for Japanese.
