摘要
试验了制作磨牙全颈环CAD/CAM内冠的全过程。首先利用三维激光测量仪对牙预备体模型进行数据测量;其次拟合重构出冠内表面;然后精确地设计修复体龈边缘处的位置和外形特征,构造出内冠三维实体模型;最后在小型高速数控铣床上加工出实物。结果表明:加工的全颈环内冠实物质量稳定、精度高,且佩戴在预备体上的贴合效果也较好。
This paper introduced the fabrication process of the fused porcelain to molar crown with CAD/ CAM technology. Firstly, preparation teeth data was retrieved by the 3D-optical measuring system. Then, we have reconstructed the inner surface designed the outer surface shape with the computer aided design software. Finally, the mini high-speed NC milling machine was used to produce the fused porcelain to CAD/CAM molar crown. The result has proved that the fabrication process is reliable and efficient. The dental restoration quality is steady and precise.
