Robust Three-Dimensional Model for Dentate Mandible with Temporomandibular Joint Based on Actual Computed Tomography Data

In this paper, numerical methods are used to build a three-dimensional (3D) model for human mandible with multi-objects from two-dimensional (2D) images captured by computed tomography (CT) scanner device. Three steps are used to evaluate realistic model; First step, segmentation techniques; are used to eliminate the undesired tissues, Second step, multi-object reconstruction technique; are used to evaluate both mandible bones and teeth, final step, texture models are generated. The output models are validated in comparison with the actual 3D model, which are generated by the CT scanner; they are meshed by tetrahedral elements to prepare the geometry for the finite elements analysis (FEA). Preliminary results are obtained for intensity measurements of teeth are presented
