Abstract

This paper reports a structural integrity analysis of a first human molar tooth. In this study, the loading condition caused by different sort of food was simulated. In order to cover a wide range, the resultant stress field evaluation was evaluated when a compressive load varied between 70N and 150 N. The finite element model was created using 3-D Computed Tomography and SCAN IP V.4 software. In the experimental analysis, reflective photoelasticity was used and the specimens were loaded with a Universal Testing Machine. The results show that stress concentrations are developed over the crown surface. The range of the top von Mises stress, for the loading cases mentioned above, is between 1.05 MPa and 3.46 MPa. The tooth geometry distributes gently the resultant stress on its root.
