摘　　要：目的:研究利用CT扫描和CAD技术建立按扣式和键槽缓压式两种不同的精密附着体义齿的三维模型。方法:采用CT扫描和CAD技术。结果:本研究采用该法建立了下颌骨及按扣式和键槽缓压式精密附着体的三维有限元模型。结论:①CT断层扫描影像结构完整,数据精确,扫描无创伤便于三维重建;②本研究建立的下颌骨及按扣式和键槽缓压式精密附着体的三维有限元模型科学准确。Objective：This study of 3-D finite element model by CT scanning and CAD technology,to build the attachment of ASC-52 and the attachment of rcvax system. Methods：Uslng CT scanning and CAD technology. Results：This study is used to establish the 3-D firite element model of the mandible and the attachment of ASC-52 and the attachment of revax systcrn. Condusion：① CT integrity and accuracy of data, scanning of non-invasive in order to three-dimensional reconstruction;② The 3-D finite element model is scientific and accuracy on the establishment of the mandible and the attachment.
