牙种植体因其可靠性和舒适性的优点而受到越来越多的关注。据估计，10%的人在一生中需要种植牙。特别是，公司提供了一个系统，供客户选择。但是，没有人研究定制的牙科植入物。传统的种植体有其局限性，由于患者口腔条件的差异，它们不能更好地适应。定制种植体的优点是精确匹配和美观外形。因此，定制植入物是可取的。定制牙种植体的另一个关键问题是制造。牙科种植体由于其复杂的特征和材料（钛）而难以加工。随着对紧公差的需求不断增加以及复杂性和精度的增加，传统的机床已经无法对其进行加工。因此，我们设计并建造了一台基于PC的CNC车铣滚刀专业加工中心，用于精确高效地加工我们定制的牙科种植体。本文介绍了我们的方法：首先，使用我们的种植体数据库设计各种口腔条件下的定制牙种植体。有限元分析结果显示了种植体-骨界面的应力分布和大小，可供临床医生参考。最后，样品由我们的加工中心自动加工。
Dental implant has been attracting more and more attention due to their advantages of reliability and comfort. It is estimated that 10% of people will need dental implants in their life time. Especially, companies offer a system for customer to choice. But, no one research on custom-made dental implants. Traditional implants have their limitation and they are not better fit due to the difference of patient's oral condition. The advantages of custom implant are accuracy fit and esthetic emergence profile. So, custom-made implant is desirable. Another key problem of custom-made dental implant is manufacturing. Dental implant is difficult to machine due to its complex features and its material (titanium). With the ever increasing demand for tight tolerance and increased complexity and accuracy, traditional machine tools have become ineffective for machining them. So, we design and built a PC-based CNC Turn-Mill-Hob professional machining center for machining our custom-made dental implants accurately and efficiently. This paper introduces our method: firstly, the custom-made dental implant in various oral conditions is designed by using our implant database. And then, FEA results indicate the stress distribution and magnitude of implant-bane interface for dentist referring. Finally, samples are automatic machined by our machining center.
