Abstract
Objective To quickly and accurately construct three dimensional finite element model of the dentu-lous mandible and conduct relevant analyses of its biomechanical properties, so as to provide reference for more researchers who focus on medical finite element analysis. Methods DICOM data of patient’s skull is obtained with cone beam CT technology. Three dimensional finite element model of the dentulous mandible was quickly constructed with Mimics software and assign the defined values to the properties of contained materials and then input into Ansys software for analysis. Results Three dimensional finite element model of the dentulous mandible was successfully constructed; material assignment of different structures of mandible was realized and its validity was verified through model load. Conclusion Three dimensional finite element models of the dentulous mandible of different material properties constructed with the method of combining cone beam CT, Mimics and Ansys soft-ware comply with the clinical circumstances and lay the foundation for further analysis of biomechanical properties.关键词
