摘　　要：提出一种面向实体模型的个体化CT图像三维重建方法,对牙齿颌骨CT断层图像进行三维重建,建立出一个可编辑的三维实体模型。为医生进行牙种植手术提供仿真工具,方便医生确定手术方案,提高手术的成功率。主要实现过程:利用螺旋CT扫描获得的人体下颌骨扫描数据,通过与Minics和UG/Imageware逆向工程技术相结合,在计算机上重建出一个可编辑的三维实体模型。它具有精确度高,可编辑性强等特点,并且可以直接用于实体的生物制造。A method of 3D solid reconstruction based on CT images is proposed in this paper ,by 3D reconstruction to dental mandible CT images in certain pitch, we get editable 3D solid models, which provide a simulation tool for dentists when carrying on dental implant surgery, facilitate dentists to determine surgery plan,and raise the success ratio of surgery. It can be realized by the following steps ： Firstly, obtain human body mandible scanning data by scanning the teeth with spiral computed tomographyth technology, then by combining with Minics and Imageware reverse engineering, construct an editable 3D solid model by computer .The 3D solid model is very accurate which can be edited and directly applied in biological manufacturing of teeth.
