Establishment of Craniomaxillofacial Model Including Temporomandibular Joint by Means of Three-Dimensional Finite Element Method
Objective The aim of this study was to establish a finite element model of the craniomaxilloface with higher biological and mechanical similarities for further biomechanical study on maxillary protraction. Methods The head was scanned by the spiral CT to acquire two-dimensional images of the craniomaxilloface. Then the original DICOM data from CT were processed by image processing softwares such as Mimics and Magics12.0 and disposed by remesh tool in Magics12.0. Finally the three-dimensional finite element model of the craniomaxilloface was constructed by the special finite element software MSC.Marc2005. Results A three-dimensional finite element model of the craniomaxilloface including the mandible and the temporomandibular joint was precisely established. Conclusions A three-dimensional finite element model of the ficraniomaxilloface including the mandible and the temporomandibular joint was precisely established. The model has a high accuracy, which will be a ideal model for further biomechanical study of the craniomaxilloface. Besides, the scientific and precise modeling method was achieved.
