Abstract: Background: Accurate replication of tooth preparations and their arch positions require impression materials that exhibit good dimensional stability. The present study was conducted to assess additional silicone and condensational silicone for the precision for duplicating master dies. Materials & Methods: The present study was conducted in the department of Prosthodontics. Two groups were made. In group I, addition silicone and in group II, condensation silicone was used. Two step impression techniques were used for both techniques and two master dies were made. Results: In group I, addition silicone and in group II, condensation silicone was used. 15 impressions were obtained with both materials. A significant difference in values of margins was recoded in both groups (P< 0.05). Conclusion: Authors found that additional silicone revealed better results as compared to condensation impression material.
