摘　　要：研究设计并开发了一套可用于颌面缺损修复的计算机辅助设计系统。系统使用视觉化工具函式库(visualization toolkit,VTK)作为开发工具。数据源可以是CT扫描获得的三维数据,也可是已经存在的.stl格式的三维表面数据。系统主要通过将健康侧数据镜像到患侧,或读入本地数据库中的数据,对缺损部位进行填充、平滑等处理,从而生成贋复体。系统还可将生成的贋复体以.stl格式输出;并利用快速成型加工系统进行加工。该系统的建立可实现颌面缺损修复中赝复体的个性化快速制作,从而提高制作质量,降低其操作难度。The presented research introduced an integrated and detailed computer-aided design process for the fabrication of a facial prosthetic to reconstruct a fine facial surface.The system was developed based on Visualization Toolkit（ VTK） with a pipeline procedure.The input data was rendered by VTK from three-dimensional CT images and / or a native file of stl format.And then,the primary model of prosthetic was established by mirroring the corresponding surface data from the healthy side or importing from a native file or database.To fabricate the prosthetic connected with the facial surface,the processes of＂Fill＂and＂Smooth＂were used.In the end,the prosthetic data was exported by the format of stl for future use and fabricating silicone prosthetic with rapid prototyping.The system simplified the process of fabricating a facial prosthetic,reduced fabrication time,and fabricating a fine prosthetic with a natural profile.
