Comparative Evaluation of Mechanical Properties of Various Elastomeric Impression Materials
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 9
Abstract
Background: During making the impression, the material needs to flow and adhere to the tooth structure and periodontal tissues that may be wetted by blood, saliva, and water. Polyether impression materials are composed of moderately low molecular weight polyether, a silica filler and plasticizer and have excellent wettability. Under the light of above evidence, we planned the present study to assess and compare the mechanical properties of various dental impression materials. Materials & methods: The present study was conducted in the department of prosthodontics of the dental institution and included assessment and comparison of mechanical strength of various elastomeric dental materials. Elasticity at break (TSb), yield quality (YS), extreme endure break (USb), and resist yield point (Sy) of seventeen monetarily accessible elastomeric impression materials with substantial (HB), medium-(MB), or light-body (LB) textures were assessed in this examination. For every impression material, 10 dumbbell-formed examples were manufactured, as per the outline depicted as sort 1 and sort C, individually. The USb (mm) and the Sy (mm) were recorded. All the results were analysed by SPSS software. Results: For Acqu- HB and Flexi- HB study groups, the mean TSb was found to be 5.45 and 5.01 MPa respectively. For Acqu- HB and Flexi- HB study groups, the mean TSb was found to be 2.90 and 2.80 MPa respectively. Conclusion: For particular use in prosthodontics dentistry, impression materials should be chosen on the basis of their specific properties.
