本文介绍一种新的拔牙法——冲拔法。重点介绍讨论了下颌阻生智齿的冲拔法,并对87个下颌智齿的牙根弯曲情况结合阻生方向进行了观察,认为近中阻生者,根尖大多向近中弯曲,垂直、远中阻生者,则大多向远中弯曲。为冲拔法的需要提出了下颌阻生智齿的分类。并对100例应用此法的下颌阻生智齿的手术时间、断根、骨折及干槽症发生率进行了统计比较。
This article describes a new method of extraction - punching method. In this paper, the impacted method of mandibular impacted wisdom tooth is discussed in detail, and the root bending of 87 lower wisdom teeth combined with the impaction direction is observed. Most of the impacted persons show that the root tips are mostly curved to the near and far, vertical and far Impacted persons, then mostly bent to the far. The need for pull-out method proposed the classification of mandibular impacted wisdom teeth. 100 cases of this method of mandibular impacted wisdom teeth surgery time, broken roots, fractures and dry socket incidence were statistically compared.
