对角分根法在下颌双根阻生第三磨牙拔除术中的应用

下颌双根阻生第三磨牙是下颌阻生第三磨牙中较为常见的类型。本文在总结临床病例及经验的基础上,对临床中常用的冠根切割法进行改良,提出对角分根法,即通过远中轴角至根分叉的连线进行分根截冠,在提高双根第三磨牙拔除效率的同时,减小手术创伤。本文就该方法的手术方法、微创力学原理和操作要点进行介绍。

Diagonal root separation method for extracting impacted double-root mandibular third molars

Double-root mandibular third molars are the common types of mandibular third molars that are prone to impaction. Based on the summary of clinical cases and experience, the commonly used crown-root separation technique is improved as diagonal root separation technique that divides the roots by the line connecting the distal axis angle to the root furcation. This new method improves the efficiency of the operation and reduces surgical trauma. This paper details the surgical method, minimally invasive mechanics, and key points of this technique, compares the technique with the crown-root separation technique, and discusses their joint applications.
