The accuracy of fixed partial dentures was examined from the point of view of three dimensional displacement of each abutment and fitness of abutment to each tooth. Using a newly developed metal die system, two types of fixed partial deuatures (soldering type and one piece casting type) were made, and the accuracy of them was measured. Conclusions were as follows : 1. In both type of fixed partial dentures, the distance between two abutments had a tendency to shorten. The each coronal axis of the abutments had a tendency to incline mesiodistally and get near at the occlusal surface side. 2. The distortion of the soldering type had a tendency to be less than that of the one piece casting type. 3. The distortion of the soldering type was mainly affected by solderitag. 4. Seating of fixed partial dentures was more affected by fitness of abutment to each tooth than by three dimensional displacement of each abutment.
