【Abstract】 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.\;更多还原
