Abstract
In order to compare the accuracy of impression method using addition silicone putty impression material, metal master die was fabricated with 4 cylindrical abutments that were similar in shape to mandibular arch. Among the 4 abutments, two(A, D) with 8mm width and 7mm height were formed in the 2nd molar regions and the other two(B,C) with 6mm of width and 7mm height were on the canine regions. Impressions were ??sken using one-step putty wash impression technique and two-step putty wash impression technique by three different types of impression materials (Perfect, Express, xaflex). Upon measuring the distance between the abutments on the model by three dimensional measuring machine, the percent of devitaion of the materials were obtained, rendering the following results. @ES The results obtained are as follows : @EN 1. There was no significant difference in accuracy in regard with the impression method between one-step putty wash impression technique and two-step putty wash impression technique using addition silicone putty impression material. 2. There were no difference in accuracy among with three different addition silicone putty impression materials. 3. All the distances between abutments on improved stone models increased in comparison with those on the metal master model.
