ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the dimensional stability and detail reproduction of five additional silicone impression materials after autoclave sterilization.</p><p><b>METHODS</b>Impressions were made on the ISO 4823 standard mold containing several marking lines, in five kinds of additional silicone. All the impressions were sterilized by high temperature and pressure (135 °C, 212.8 kPa) for 25 min. Linear measurements of pre-sterilization and post-sterilization were made with a measuring microscope. Statistical analysis utilized single-factor analysis with pair-wise comparison of mean values when appropriate. Hypothesis testing was conducted at alpha = 0.05.</p><p><b>RESULTS</b>No significant difference was found between the pre-sterilization and post-sterilization conditions for all locations, and all the absolute valuse of linear rate of change less than 8%. All the sterilization by the autoclave did not affect the surfuce detail reproduction of the 5 impression materials.</p><p><b>CONCLUSIONS</b>The dimensional stability and detail reproduction of the five additional silicone impression materials in the study was unaffected by autoclave sterilization.</p>
