摘要：

背景：颅颌面部是骨骼系统中结构最复杂、功能最多样的的结构之一，要进行颅上颌骨复合体生物力学分析，就必须建立一个精准的三维有限元模型。
目的：探索快速建立完整颅上颌复合体三维有限元模型的方法。
方法：以牙列完整、咬合关系正常、磨牙为中性关系、牙周组织健康的成年志愿者作为建模素材，进行多层螺旋CT扫描,利用Mimics软件和MSC.Patran软件建立颅上颌复合体三维有限元模型。
结果与结论：探索出一条快速建立颅上颌复合体三维有限元模型的新方法。建立了三维坐标系下的可以从任意角度观察的健康人颅上颌复合体三维重建生物医学模型和三维有限元模型，由76 035个节点和373 819个单元组成。该模型具有较好的几何相似性和力学相似性。

Abstract:

BACKGROUND: Cranial-maxillary complex is one of the most complex and versatile structure in the skeletal system. For the biomechanical analysis of cranial maxillary complex, it is necessary to establish a precise three-dimensional finite element model
OBJECTIVE: To develop an effective and feasible method to construct the three-dimensional finite element model of cranial-maxillary complex. 
METHODS: A voluntary healthy adult with normal relationship, healthy periodontal tissues and temporomandibular joint was chosen for model establishment. Multi-slice CT scan in combination with Mimics software and MSC.Patran software were used to prepare the three-dimensional finite element model of cranial-maxillary complex.
RESULTS AND CONCLUSION: We had explored out a new quick construction method of maxillary complex. A 3D FEM of normal maxillary complex was constructed. It included 76 035 nodes and 373 819 elements. It could be observed at any dimension. The finite element model had better biomechanical characters.
