摘　　要：目的:探索快速建立单侧完全性唇腭裂上颌骨三维有限元模型的方法。方法:对单侧完全性唇腭裂患者头颅部进行多层螺旋CT扫描,利用Mimics软件直接将CT扫描样本得到的Dicom标准文件进行处理,并导入逆向工程软件Geomagic Studio来构建模型的表面,在此基础上用Ansys软件建立完整的单侧唇腭裂上颌骨三维有限元模型。结果:建立了由27405个实体单元和26876个节点组成的单侧完全性唇腭裂上颌骨有限元模型。结论:应用螺旋CT技术和联合使用Mimics软件、Geomagic Studio软件对模型进行构建,并结合Ansys软件生成三维有限元计算模型,是一种快速有效地建立单侧完全性唇腭裂有限元模型的方法。Objective To explore a faster and more precise method to establish a 3-dimensional （3 D） fi- nite element model of maxillary in human complete unilateral cleft lip and palate. Methods The surface of the model was created using Materialists Interactive Medical Image Control System （Mimics） software to deal with Di-corn standard files obtained by scanning the cranium of the patient with multi-slice helical CT. The 3D finite ele- ment model for complete unilateral cleft lip and plate in maxillary was established by Ansys software. Results A 3 D finite element model of maxillary in human complete unilateral cleft lip and palate was constructed with 27 405 units and 26 876 nodes. Conclusion The combination of Mimics software, Geomagic studio software, Ansys soft- ware, and spiral CT is able to create a 3D finite element counter model, which provides a faster and more valid method to study complete unilateral cleft lip and palate.
