Biomechanical Stress Analysis of Mandibular First Permanent Molar Restored with Different Restorative Materials : A 3-Dimensional Finite Element Analysis.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Normal mastication with its varying magnitude and direction generates extensive intransigent stresses in teeth and their supporting tissues. The structure of the human tooth and its supporting tissues is a multifarious assemblage of materials of various mechanical properties. Finite element method (FEA), a modern technique of numerical stress analysis has great advantage of being applicable to solids of irregular geometry and heterogeneous material properties. It is therefore ideally suited for the examination of the structural behaviour of teeth. Three- dimensional Finite Element Analysis was used to compare Stress distribution generated in Class II MOD lesion using different restorative materials. Results: Software performs a series of calculations and mathematical equations and yields the simulation result. The models was restored with different restorative material which was subjected to a force of 450 N and 600 N loads. Mechanical Properties were analyzed and compared in different materials. From the results of the study, it can be concluded that ClearFil AP-X performed best followed by other restorative materials.. Conclusion: Restoration of Class II MOD lesions with materials of higher modulus of elasticity will enable better stress distribution.
