Evaluation of flexural strength of two commonly used provisionalization materials: An in-vitro study
Journal Title: Harsukh Educational Charitable Society International Journal of Community Health and Medical Research - Year 2017, Vol 3, Issue 2
Abstract
Background: One of the established treatment modality for treating patients with partially edentulous Abstract spaces is the fixed partial dentures. Because these restorations are made indirectly in a dental laboratory, several days or weeks are usually required for their completion. Therefore provisional restoration is an essential step in fixed prosthodontics. Hence; we planned the present study to assess the flexural strength of two commonly used provisional restoration materials.Materials & methods: The present study included assessment of flexural strength of heat cure resin and auto polymerization resin materials when used as provisional restorative materials. Heat polymerizing PMMA & self polymerizing PMMA are most commonly used materials available in powder & liquid form. The materials were mixed according to the manufactures instructions. They were packed into the mold and allowed to bench cure for 20 minutes under a constant pressure of 500 gm. Universal force testing machine was used for testing the forces of the standard specimens. All the results were recorded and analyzed by SPSS software. Results:Significant results were obtained while comparing the mean elastic modulus in between the specimens of the two study groups. Maximum amount of elastic modulus found in specimens of group of heat polymerized resin was found to be 852.22 mPa while in the group of Auto polymerizing resins, the maximum amount of elastic modulus was found to be 423.25 mPa respectively.Conclusion: Heat polymerized resin materials have higher Elastic modulus in comparison with the Auto polymerizing resins materials.
