Abstract

Introduction: Dimensional accuracy when making impressions is crucial to the quality of fixed prosthodontics treatment, and impression materials are critical factors affecting this accuracy. The purpose of the study was to evaluate and compare the dimensional accuracy of resultant casts made by monophase polyether and monophase addition silicone impression materials. Materials and Methods: A stainless steel model containing two complete-veneer, fixed partial denture abutment preparations was fabricated with standardized specifications that served as a control. This was then used to compare the impression materials. Seventy gypsum casts were obtained, 35 from each impression material. All the impressions were made in stainless steel perforated custom tray. A tray space of 2 mm was provided for the impression material. Impressions of the stainless-steel model were made using monophase polyether and monophase addition silicone impression material. The accuracy of the two impression materials was assessed by measuring three dimensions (intra- and interabutment) (10-µm accuracy) on stone casts. One-way analysis of variance and Student’s t-test were used for statistical analysis. Results: No statistically significant differences were observed in the dimensional accuracy of stone dies obtained with both materials as compared to those of the stainless-steel model (p > 0.01). Conclusions: Within the limitations of this study, it was found that there was no significant difference in the dimensional accuracy of resultant casts made by monophase polyether and monophase addition silicone impression materials. However, the dimensional measurements of casts fabricated from monophase addition silicone were found to be closer to control as compared to monophase polyether.
