计算机辅助设计制作上颌骨修复体的实验研究

目的利用计算机辅助方法设计制作上颌骨个体化修复体。方法通过CT扫描获取上颌骨三维数据信息,运用三维重建、镜像及快速原型技术获得模拟修复上颌骨模型,在此基础上利用铸造法完成个体化上颌骨修复体的制作。结果以CT扫描获取上颌骨三维解剖信息为基础,通过计算机辅助设计成功制作上颌骨个体化钛网修复体。结论在CT扫描获取上颌骨原始解剖信息的基础上通过计算机辅助设计制作过程能够成功构建上颌骨个体化功能性修复体。

Computer-assisted individualized reconstruction of maxillary defect

Objective To study the feasibility of developing an individualized functional reconstruction of maxillary defects with computer aiding.Methods Based on collection of CT slices of the maxilla,an individualized functional titamium mesh for maxillary reconstruction was developed with 3-dimensional reconstruction technique, mirror technique, rapid prototyping technique and fitanuim casing technique. Results Based on the CT data of the maxilla an individualized titanium mesh of maxillary defect was developed. The titanium mesh could restore the maxillary defects individually. Conclusion An individualized functional reconstruction can be successfully developed with computer aiding. The study may provide a new method for clinical reconsrucfion of maxillary defect.
