Evaluation of Additional Silicone and Condensational Silicone for the Precision for Duplicating Master Dies: A Comparative Study
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2018, Vol 6, Issue 1
Abstract
Background: Achieving optimum function and esthetic of restorations is very important, especially in replacing a missing tooth. Several elastic impression material silicones are available for dental use: Synthetic elastomeric materials (polysulfide [PS], additional silicone [AS] and condensational silicone [CS], and polyether [PE]); and hydrocolloids. Hence, the present study was conducted to compare additional silicone and condensational silicone for the precision for duplicating master dies. Materials & methods: In the present study, we prepared an acrylic model of lower 1st molar tooth on the basis of conventional shoulder type marginal preparation, supragingivally. Two master dies were made by both impression materials. A total of 20 successive impressions were then made, ten for each of the two impression material. The marginal discrepancy was recorded in both the study groups. All the results were analyzed by SPSS software. Results: Significant results were obtained while comparing the mean discrepancy in between duplicated die and model in the condensation silicon group. Conclusion: In comparison to condensation silicone, additional silicone is a better impression material.
