摘　　要：根据人体下颌骨的螺旋 CT扫描图像 ,利用三维重建、图像处理和网格划分技术 ,建立了人体下颌骨的三维有限元模型。根据颞下颌关节的解剖结构及其力学特点 ,将已建立的下颌骨模型通过关节和经过修改的Hybrid 假人头部模型相连接 ,从而建立一个具有解剖基下颌的人体头部有限元模型。根据已有的尸体实验结果 ,验证了模型的可靠性。A finite element model of human mandible is developed from CT scan images by the technologies of three-dimensional reconstruction, image processing and meshing. The mandible model is connected to one modified head model of Hybrid Ⅲ dummy with joint according to the anatomic structure and mechanical characteristics of the temporomandibular joint. Then a finite element model of the human head with the true anatomic structure mandible is developed. This model has been validated with the cadaver test results, it can be used in researches on the mechanism of craniofacial blunt-impact injury and on the assessment of injury severity.
