临床上,由于解剖差异,用力不当等原因,在拔除阻生第三磨牙时,常常出现断根,这是牙槽外科较棘手的一个问题,本文总结作者的临床经验,就下颌阻生第三磨牙拔除术中断根为处理作一介绍。 为了便于断根的处理、作者主张将断根分为根分叉上根折和根分叉下根折。 1、根分叉上根折的处理: 如果断根不是很松动、容易取出、先应分根。一般分根用牛角钳、骨凿、牙挺和牙钻四种方法。可先使用牛角钳,如髓底组织强度高,可取出断根;如髓底强度差,也可达分根目的。如牛角钳不能达此目的,再使用
Clinically, due to anatomical differences, such as improper use of force, removal of impacted third molars, often appear to cut the root, which is more difficult alveolar surgery a problem, this article summarizes the author's clinical experience, the third impacted mandibular molar Removal surgery interruption root for the treatment of an introduction. In order to facilitate the treatment of root disconnection, the author advocates that the root can be divided into the upper branch root root and the lower root root branch. 1, root fork on the root of the deal: If the root is not very loose, easy to remove, should be divided into roots. General points root with horns pliers, bone chisel, teeth Ting and dental drill four methods. You can use the horns pliers, such as high strength of the medullary tissue, can be taken off the root; such as poor medullary strength, but also up to the root. Such as the horns can not achieve this purpose, then use
