The purpose of this study was to investigate and compare the accuracy of working casts made from two methods (transfer-pin type and stone type). In addition, the cause of distortion of working casts was examined, impressions were made from an implanted metallic model of a simplified mandibular dentition, and working casts were measured using the three-dimensional measuring microscope.<BR>The results were as follows:<BR>1. The distortion of reference points, other than in the implanted area, for both the transfer-pin type and the stone type casts had a similar tendency.<BR>2. In the implanted area, the reference points on the occlusal screw had a different tendency with relation to the amount of distortion and direction, the height and inclination of the abutments had different tendencies, and the stone type casts were more accurate than the transfer-pin type casts.<BR>3. The existence of impression spacers and transfer-pins and the error of operation must be considered as probable causes of the differences of accuracy of the two types of casts.<BR>4. The working casts made from the new method (using an implant head) were as accurate as the stone type casts.
