摘要
目的 开发建立颌面缺损修复计算机辅助设计 (CAD)技术。方法 通过对一例耳廓缺损和一例眼缺损患者修复的实例 ,详细介绍应用镜像技术、布尔运算及FreeForm软件等图像处理方法与相关软件 ,建立的颌面缺损修复CAD技术。结果 建立了颌面修复CAD技术。成功地完成了眼、耳缺损修复的CAD过程 ,方便而快速地获得了缺损区耳廓、眼的三维图像与数据 ,为进一步实现计算机辅助制作 (CAM)打下基础。获得的图像对称性好 ,修复体与组织面良好贴和。结论 本项研究建立的颌面缺损修复CAD技术 ,能基本解决颌面部常见缺损 ,具有较高的应用价值 ,可以在临床推广应用。
Objective To establish a CAD system of maxillofacial prostheses.Methods The maxillofacial prosthesis CAD system, which included mirror technique, boolean operation and use of FreeForm software, was introduced in detail by use of two clinical cases of auricular and orbital prostheses. Results The CAD system of maxillofacial prosthesis was successfully established. The 3 D digital images of defected sides of two cases were quickly and conveniently obtained, which were symmetrical and harmoniously match to the deficient sides. Conclusion The established CAD technique is a useful system in maxillofacial area. It may be applied in clinic in future.
