Abstract

The purpose of this study was to investigate the accuracy of working casts fabricated by a transfer system. A master model was fabricated from a single standing ITI implant with a solid abutment. Working casts were fabricated from two methods.(One was a stone-model using the conventional method, and the other was a transfer-model using the transfer system with an impression cap and a shoulder analog.) A profile projector was used to measure the dimensional changes of dies. The conclusions were as follows:<BR>1. Regarding the dimensional change of dies on transfer-models, the width of the joint part and the height of the shoulder were as accurate as those on stone-models; however, the width of the abutment was slightly small, and the height of the abutment was slightly large.<BR>2. The distortion of reference points on stone-models had a tendency toward upper and outside. On transfer models, reference points of the upper part of the abutment had a similar tendency, however; those of the joint part and the shoulder edge distorted toward lower.<BR>3. The distortion of the center point on stone-models had a tendency toward upper; however, that on transfer-models scarcely distorted.<BR>4. On both models, there was little inclination change in the long axis.
