ASSESSMENT OF DIFFERENT ELASTOMERIC IMPRESSION MATERIALS USED IN FIXED PROSTHODONTICS: A COMPARATIVE STUDY
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 5
Abstract
Background: The hydrophilicity of the impression materials is fundamentally essential to wet the hard and delicate tissues in the mouth and to make precise impressions and casts. Considering the effect of hydrophilicity on precise bite the dust casting, lacking wetting brings about gypsum throws and kicks the bucket delivering pits and voids situated in basic ranges, for example, edges, stick openings, and retentive grooves. Hence; we planned the present study to compare the dimensional stability and accuracy of selected elastomeric impression materials at various time intervals. Materials & methods: The present study included assessment of dimensional stability and accuracy of selected elastomeric impression materials at various time intervals. All materials assessed were light-body consistency except for the polyether which is produced in just a single consistency. Light-body material was utilized on the grounds that it permits insinuate propagation when impressions are made. A round stainless steel kick the bucket was utilized to think about the examples at room temperature and stickiness. Five examples of every material were assessed. The examples were tried at prompt expulsion from shower, at 1, 24, 48, and 72 hours, and at 1 week after set. All the results were analysed by SPSS software. Results: Omniflex and Permlastic were the two impression materials used in the present study. At 144 hours, the deviation in Omniflex and Permlastic group was 0.55 and 0.35 respectively. Conclusion: Impression materials that were poured promptly and assessed utilizing a custom plate and cement reliably exhibited better outcomes in examination than those tried without the custom plate.
