摘　　要：针对中切牙缺损的情况,我们介绍了一种利用计算机辅助技术设计制作贴面的方法。该方法首先利用三维激光测量仪对牙预备体模型进行数据测量;利用逆向工程软件重构预备体的三角网格模型,并通过提取预备体边缘线、镜像完整切牙、局部自由变形等操作完成贴面三维模型的构造;最后在小型高速数控铣床上加工出实物。结果表明加工的贴面实物质量稳定、精度高,且佩戴在预备体上的贴合效果也较好,满足了美观的要求。In view of the instance of a damaged medial incisor,we have introduced a method using computer aided technology to design and manufacture thelamiate veneer. Firstly, the data on preparation teeth was retrieved by the 3D optical measuring system. Secondly, the triangle mesh model of preparation teeth was reconstructed by using the reversion project software.And the 3D model of the laminate veneer was constructed through some operations, such as extracting the edge line of preparation teeth, mirroring the integrity incisor and local freeform transform. The result has proved that the fabrication process is reliable and efficient. The dental restoration quality is steady and precise. The artifical laminate veneer has met the request of esthetical syrmnetry.
