Development of metal sheet denture plate with a CAD/CAM system

一种采用渐进成形技术生产纯钛义齿的柔性工艺正在开发中。随着老龄化社会的到来，义齿托板是全口义齿的重要修复体。本研究将渐进板材拉伸成形技术应用于纯钛义齿板材的制备。然而，这一过程带来了癫痫抵抗力差的难题。为了提高表面质量，对阳极氧化膜进行了测试。虽然氧化膜表现出良好的抗咬合性，但在一定区域内会产生可重现的滑动痕迹。系统地研究了成形针进给速度和表面斜率对表面粗糙度的影响。过大的进给速度增加了粗糙度，这是因为刀具痕迹很深。由于与刀具的严重滑动接触，小进给速度增加了粗糙度。结果证实了粗糙度最小的最佳条件的存在。但我们可以改变提高钛义齿板几何精度的系统，其他从牙科模型扫描的输入接口。

A flexible process for pure titanium denture plate using incremental forming technology is being developed. Denture plate is a important dental prosthetic component of complete denture with the aging society. In this research, incremental sheet metal stretch forming was applied to fabrication of pure titanium denture plates. This process, however, posed difficult problems about poor seizure resistance. In order to improve the surface quality, anodic oxide film was tested. Although the oxide film showed good seizure resistance, reproducible sliding marks were produced in a certain region. The effect of the feed rate of forming stylus and the slope of surface on the roughness was investigated systematically. The excessive feed rate increased the roughness because of deep tool marks. The small feed rate increased the roughness due to the severe slidingcontact with tool. The results confirmed the existence of optimum condition in which the roughness was minimized. But we can change the system that improvement of geometrical accuracy for titanium denture plate, other input interface of scanning from dental models.
