Purpose: The aim of this investigation was to evaluate and compare the dimensional accuracy of hydrophilic polysiloxane, vinyl polysiloxane (VPS), and polyether (PE) impression materials under dry, moist and wet conditions. Methods: An acrylic master model including 6 implants was formed, and 108 impressions were made up of this acrylic model at total. In this study, the materials of hydrophilic polysiloxane impression material, 1 hydrophilic vinyl polysiloxane impression material and 1 polyether impression material were tested. Twelve impression of each material were created under dry, moist and wet respectively. Two reference distances were evaluated on each study model by using a graphics-editing program whereas for comparison of mean dimensional changes one-way analysis of variance and Student t-test were used. Results: One-way analysis of variance revealed significant differences between impression materials and conditions (P < 0.05). There was a statistically significant difference between wet and dry-moist conditions (P < 0.05). The best result is with polyether impression material under dry condition (0.15 mm-mean difference). Conclusions: All impression materials showed a statistically significant difference under dry, moist and wet conditions.
