The purpose of this study was to evaluate the accuracy of digitized elastomeric impression materials of crown abutment, using non-contact whitelight scanner and virtual three-dimensional superimpositional analysis. The stone models and impressions were digitized white light scanner tocreate three-dimensional surface models. Stone models were used as CAD reference model (CRM). The resulting point clouds (ASC file) fromdigitization of impressions using converting software. Discrepancies between the points in the point clouds and CRM were measured bysuperimpositional software. Mean and standard deviation of values of discrepancies were analyzed by one-way ANOVA and multiple comparison(α=0.05). The mean discrepancy between the impressions for the extra-light body (XLB), light body (LB), and heavy body (HB) group were5.10±1.45 μm, 6.30±1.87 μm, 9.80±1.52 μm, respectively. The different impression materials affected the digitization of impressionssignificantly (p＜0.05). As a result, digitization of elastomeric impression materials on dental scanner was influenced by material sort.
