Abstract
This study explains and demonstrates how to construct the 3-D finite element model of dent facial complex with the original DICOM data of CT, for the analysis of their biomechanical characters. The establishment of 3-D finite element model of maxillary complex: spiral CT scanner, then CT workstation outputted CT images in DICOM format to personal computer, using ANSYS and Mimics software established the 3-D finite element model of maxillary complex of human being. The establishment of maxillary complex three-dimensional finite element model, which was made up of 350125 units and 583391 nodes, included maxillary, arch wires, teeth of 14, maxilla cavity structures. Model and modeling were of the same size with a good geometric similarity. It had scalability which made it possible to attach brackets and wires, implants to start-related studies. The finite element model had better biomechanical characters. It was feasible and effective to the stress analysis in the process of orthodontic treatment.
