摘要/Abstract

摘要： 目的：将计算机辅助设计与快速成型技术相结合，应用于牙冠延长术手术模板的设计与制作，初步探索可行的方案。方法：利用三维扫描仪对1位需行牙冠延长术患者的上颌牙列石膏模型进行扫描。遵循龈缘形态的美学原则，结合患者口腔实际情况，对点云数据进行编辑，生成代表龈缘形态的3D曲线。按照曲线位置确定模板区域，通过抽壳等操作获取模板的三维数据模型。最后将数据导入快速成型机，加工出树脂模板。结果：初步实现了牙冠延长术手术模板的计算机辅助设计与制作；提高了术中定位切口的速度和准确性。结论：计算机辅助设计与快速成型技术相结合制作牙冠延长术模板，为科学设计龈缘的位置和形态提供了一种可行的方法。

Abstract: PURPOSE: To introduce a method applied in computer aided design and computer aided manufacture (CAD-CAM) of template for crown lengthening. METHODS: Point cloud data of dental stone model of the patient in the plan of crown lengthening surgery was obtained by laser scanning. The following processes were carried out, constructing 3-D curve of the gingiva, drawing template outline on the triangle mesh model, shelling it for 3-D model of template, and transferring the data to rapid prototyping equipment for manufacture. RESULTS: 3-D model of the template was preliminarily accomplished. The resin template was manufactured with rapid prototyping equipment. The fitness between resin template and plaster model was good. CONCLUSIONS: This method, as an integrated procedure including data acquisition, 3-D computer modeling and fabrication by rapid prototyping, is feasible to implement CAD-CAM of template for crown lengthening.
