桩冠是修复某种缺损牙齿的一种良好方法,但在制造过程中是相当细致复杂的。它是利用结实不松动的牙根,在根的中间(即根管)插上一根金属棒,再在棒上部作一个人造牙联成一体,即为桩冠。标准的桩冠须具有牢固、舒适、美观、逼真和恢复原有的生理功能等要求才为合格,因此在操作过程中是比较繁杂和需要较长的时间。过去做一个桩冠,在技术和设备条件较好的情况下约需复诊三、四次,共四天次的时间才能完成,并且费用也很大,不适宜一般群众的经济情况。自从经过了伟大的整风运动,提高了阶级觉悟,较变了服务态度,同时解放了思想,因而在短短的几天内试验成功了“桩冠快速操作法”。具体操作步骤和方法: 一、检查:首先应注意分龈、牙槽骨的健康情况, Post crown is a good way to repair some kind of missing tooth, but it is quite complicated in the manufacturing process.

The standard crown shall be qualified for its strong, comfortable, beautiful appearance, lifelikeness and the restoration of the original physiological functions. Therefore, it is more complicated and takes longer time to operate. In the past to do a pile of crowns, in the case of better technology and equipment conditions about the need for referral three or four times, a total of four days time to complete, and the cost is also great, not suitable for the general public economic situation. Since the great rectification campaign was carried out, the class consciousness was improved, the service attitude was changed, and the thoughts were liberated at the same time. As a result, the test of “rapid operation of pile crown” succeeded in a few days. Specific steps and methods of operation: First, check: First, pay attention to sub-gingival alveolar bone health,
