笔者通过多年的口腔临床实践,摸索出一种拔除露根乳牙的简便实用方法。此法既不用麻醉,且手术简便迅速,患儿痛苦亦小。现简介如下:器械:除一套口腔检查盘外,只需骨锤一个,窄头骨凿(旧的也可)一个。方法:令患儿端坐牙科椅上,消毒术区,左手握骨凿柄端,将骨凿头置于露出的根尖上,使骨凿凹面朝根尖,骨凿凿身与牙体垂直。右手握小锤,在靠近根尖处的骨凿上快速敲击一下,相当于劈牙的暴发力(注意要用巧力,用力不可太猛)利用小锤的惯性力, Through years of clinical practice in the mouth, the author explored a simple and practical method for removing root of exposed roots. This method neither anesthesia, and the operation is quick and easy, children suffering is small. Now briefings are as follows: Instruments: In addition to a set of oral examination disc, only a bone hammer, narrow skull chisel (the old can be) a. Methods: The children sit on the dental chair, disinfection area, the left side of the handle bone chisel handle, the bony head placed on exposed root tip, so that the concave surface of the bone chisel apical bone chisel body perpendicular to the tooth. Right hand holding a small hammer, quickly knocking on the bone chisel near the apex, which is equal to the explosive force of the split-teeth (note that use of clever force can not be too hard) the use of hammer inertia force,
