ABSTRACT
The goal of the study is to design a realistic and accurate three-Dimensional (3D) dental model that does not incorporate approximation for use in Finite Element Analysis (FEA). A segmentation is carried out on the images resulting from a micro-CT acquisition and makes it possible to differentiate the various components of the teeth (enamel, pulp, dentin). Reconstruction does not use Boolean operations, so approximations are avoided. A class II MOD cavity is simulated on the tooth and different types of restorations (ceramic and composite) are set up for finite element calculations. The results showed that the concave parts of the occlusal table, the cavosurface angle of the cavity, the internal angles of the restorations and the cervical area of the tooth are stress concentration areas.
