Description

一种医用口腔磨削装置 技术领域
本发明涉及医疗器械技术领域，具体涉及一种医用口腔磨削装置。
背景技术
牙套又称齿列矫正器或牙箍，是齿列矫正所使用的一种装置，用来校准牙齿至适当的咬合位置。被用来改善咬合不良，包括戽斗、龅牙、哨牙错咬、开咬、牙齿弯曲或其他各式各样的齿颚方面的缺陷等等，其目的是美容或是牙齿结构上的调整，通常会配合其他齿列矫正的装置，可用来拉大上颚或下颚，制造牙齿间的空间；或是改变齿颚的外观。现有的牙套种类大致可以分为：普通钢牙套、舌侧牙套(隐形牙套)、陶瓷牙套、无托槽牙套、自锁牙套(钢自锁、陶瓷自锁)等。其中钢性牙套因其性价比高，使用最为普遍。但是在使用钢性牙套时，一般会配合使用钢丝来紧固刚性牙套，但是钢丝的切口过于锋利，并且难以处理，在口腔中使用时非常容易伤到口腔内部软组织，对口腔造成一定的伤害。
因此为了解决这一问题，发明一种用于打磨金属牙套或主钢丝切口的医用口腔磨削装置具有积极的意义。而关于这种医用口腔磨削装置目前还未见报道。
