Abstract:

BACKGROUND: Bilateral-sagitta-split-ramus-osteotomy (BSSRO) is a useful method for orthognathic surgery; finite element method is an important approach in studying BSSRO biomechanics.
OBJECTIVE: To explore an easier and more precise method for establishment of the three-dimensional (3D) finite element model of mandible BSSRO and lays foundation for the research of biomechanics after BSSRO.
METHODS: CT faultage image was analyzed by thin-layer CT, Dicom standard and Mimics software combined with MSC.Patran software.
RESULTS AND CONCLUSION: A 3D finite element model of mandible BSSRO was established. Dicom standard and Mimics software were used to obtain the CT images and write the digital data to MSC. Patran software directly, which increased the efficiency of establishment of the 3D finite element model. It is indicated that the application of thin-layer CT and Dicom standard make the establishment of finite element model more precise. Meanwhile, BSSRO was directly established by Mimics software, the application of Mimics software can improve the efficiency of establishment of the 3D finite element model to a large extent, and lays foundation for biomechanics analysis.
