摘　　要：运用计算机图象分析系统处理牙颌及修复体标本的切片或 CT断层图象 ,将待分析的三维结构在断面上的形态转换为图形 ,用图形数据后处理软件进行定标运算、坐标修正、平滑去噪与有限元分析软件格式转换 ,研究成功了一种用于有限元分析的牙与牙颌及修复体的三维形态数字模型的建立方法。In this paper, the images of sliced sections or CT sections of the specimen of teeth, jaw and prosthesis were processed by a computer image analysing system, and the plane shape of the 3 D objects of interest on the sections was converted into digital images using a special software module for contour analysing. Then the images were adjusted in scale,modified in coordinates and smoothed in shape, and the data format was transferred for finite element analysis by a specially designed software. In such ways a method for the digital modelling of the 3 D shape of teeth, jaw and prosthesis was successfully established.\;
