%X A method of 3D solid reconstruction technology based on CT image is proposed in this paper,and it is applied to tooth CT image.We get an editable 3D solid model,which is used for dentist to stake in the broken tooth and analyze the stress of the stake during the tooth repair.It can be realized in the following steps:Firstly,get the CT images by scanning the tooth with spiral computed tomography in a certain pitch;Secondly,get rid of the noisy points of the 2D image data and convert it into 2D digitized contour data;Finally,the 3D wire frame is reconstructed by offsetting the 2D digitized wire frame in the certain pitch,get the tooth solid model using the face which is lofted with the 3D wire frame.The 3D solid model is very accurate which can be edited and processed arbitrarily and applied directly in biological manufacturing of tooth.
