Data of tooth surface before and after wear were both obtained through laser scan system. The images were then reconstructed by SURFACER software.(2) C language program used of improved iterative closest point algorithms was developed to registrate imagines before and after wear. Standard plan was defined to the overlapped imagines after registration, then wear quantity was measured.￤ear was imitated by tooth brush machine which was made by STOMATOLOGY COLLEGE FORTH MILITARY MEDICAL UNIVERSITY.

应用三维激光扫描仪采集牙模型的表面数据，在计算机中用SURFACER逆向工程软件重建牙表面；②运用最近邻点迭代匹配算法加以改进，编制 C语言程序，配准磨耗前后的三维图像，在确定基准平面后，计算磨耗前后的体积变化量；③用口腔医院自制刷牙机进行模拟磨耗，用传统称重法，通过电子天平测试件的重量变化，用失水法计算测试材料的密度，换算成体积。

Based on the example of turbine reverse engineering , the general procedure that can be used to translate the physical object into CAD datum by Surfacer software is determined in this paper1 By going deep into the vector of point-cloud , it's parametrization can be gained by adopting the precept of accumulating chordal parametrization1 According to the principle of const ructing curve using the least square method , the high quality-curve can be gained by modifying curve's parameter1 This paper also empha2sizes on some methods about processing point-cloud , const ructing curve and const ructing surface1 And it can provide several methods to const ruct high quality2CAD model for mould machining1
