Comparison of Different Mesh Density Parameters on Mandible Segment

Objectives: In this paper a CAD model of a mandible with different density of a mesh structure is presented. Methods: In the first step, on a previously segmented CT model, a 2D mesh was applied. Then, the conversion of tetrahedral elements had followed for the purpose of CAE analysis. On several segments of the mandible, it has been shown the quality of generated mesh in relation to the number of network elements. Results: All the mesh settings are analyzed and shown in the table. The quality of generated mesh is playing a main role in different flavors of a numerical analysis such as FEM - finite element method, FDM - finite difference method, FVM - finite volume method. Number of elements in generated mesh has an important influence on the obtained results. Conclusions: Mentioned methods enable different types of analysis and simulation that can be used in several cases: planning and design of the implant, the analysis of existing clinical status and planning the reconstruction of bone defects, making epithesis and opturators.
