Abstract - Objective: This study describes the Thermo-Mechanical analysis of restored molar tooth crown for determination of the stress levels due to thermal and mechanical loads on restored molar tooth using Finite Element Analysis on 3-D model generated using MIMICS 9.11.

 Methods: A molar tooth was digitized with a micro-CT scanner. Molar tooth surface contours of enamel and dentin were fitted in bone, segmentation was done based on pixel density using a thresholding in interactive medical image control software MIMICS 9.11.lis file was imported in a finite element softwareANSYS14.0 (Ansys, Inc., USA) to create 3D solid model, where different temperature and boundary conditions were applied considering different materials for molar tooth crown.

 Results: The potential use of the 3-D model was demonstrated and analyzed using different materials for crown. Thermal strain, Stress and deformation was measured at hot and cold conditions in ANSYS and correlated with analytical calculation and existing experimental data for model validation and optimization.

Conclusion: The described method can generate detailed and valid three-dimensional finite element model of a molar tooth with four different layers crown, adhesive cement, tooth and bone considering different restorative materials. Among different materials Stainless steel, Porcelain, Ceramic. Porcelain with resin cements layer present safe stress and deformation at cold and hot condition.
