拔牙有时会拔断牙根,这是难于避免的,特别是多根牙拔除时还可两个或三个牙根同时折断。多根牙位置比较后,断根的部位又往往发生在牙根的中部或靠近根尖处,这样的断根可叫低位断根,其位置又后又深,取除时常会造成一定困难。按一般取断根的方法有:(1)根钳取根法,只适用于高位断根,即牙颈部断根者,而对低位断根便无能为力了;(2)根尖挺取根法,常要借取于骨锤,即用锤将根尖挺楔进断根与牙槽骨之间,再将断根撬出。但用锤敲击,不但造
Tooth extraction sometimes pull the root, which is difficult to avoid, especially when multiple root removal can also be two or three roots at the same time broken off. After comparing the position of multiple teeth, the root part of the root often occurs in the root of the root or near the apical place, so that the root can be called low root, its location and then deep, removal often cause some difficulties. According to the general take the root of the method are: (1) root clamp take the root method, only for high root, that is, the root of the cervix who cut off, and the root of the lower will be powerless; (2) Borrowed from the bone hammer, that is, using a hammer to wedge the apical wedge into between the root and alveolar bone, and then pry out the broken roots. But hammering, not only made
