概要

The accuracy of the impression materials was examined by taking measurements on each stone cast constructed from EXPRESS and four other kinds of impression materials. The results are obtained were summarized as follows. 1. There was no difference in the measurements of each stone cast constructed from rubber impression materials, except for a slight expansion. The stone cast constructed from alginate impression material showed slight expansion compared to those constructed from the rubber. 2. Apexes of stone casts were the sharpest in the decreasing order of EXAFLEX, SURFLEX, EXPRESS, XANTOPREN, and HI-TECHNICOL. 3. The surface of the stone cast constructed from alginate impression material was the roughest, the others were not so rough and similar. 4. Alginate impression material showed good wetting. There was no difference in the measurements of each rubber impression material, except for poor wetting. 5. The accuracy of the measurement for stone casts constructed from EXPRESS was not different from that for the other rubber impression materials.
