摘要
对单侧完全性唇腭裂患者颅颌面部进行多层螺旋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。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。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,是一种快速有效的建立单侧完全性唇腭裂有限元模型的方法。
Skull maxillofacial region of patients with complete unilateral cleft lip was subjected to multi-slice spiral CT scanning. Dicom standard files of the CT scanning were processed by Mimics software and import to Geomagic Studio to create the surface of model. The three-dimensional finite element model of complete unilateral cheilopalatognathus in maxillary was established by Ansys software. A three-dimensional finite element model of maxilla of the patient with complete unilateral cheilopalatognathus was constructed with 27 405 units and 26 876 nodes. The combination of Mimics software, Geomagic Studio software, Ansys software, and spiral CT is able to create three-dimensional finite element model, which provides a fast and valid method to establish model of complete unilateral cheilopalatognathus.
