摘要：

随着治疗观念的不断进步,拔牙术后并发症的预防成为口腔外科医生的重点关注话题。由下颌第三磨牙拔除造成的下牙槽神经永久性损伤而导致的下份面部感觉异常严重影响着患者的生活质量。20世纪末,截冠术从修复领域引入口腔外科领域,经过多年的实践,其在安全性、可操作性、并发症发生率等方面皆有良好的表现。本文通过对截冠术这一术式进行回顾性综述以期为下颌第三磨牙拔除的临床实践操作提供新思路。

Abstract:

The prevention of complications after exodontia has drawn increasing attention from oral surgeons. Malfunction of the inferior alveolar nerve, including paresthesia, following the extraction of the mandibular third molar extensively affects the quality of patients’ lives. At the end of the 20th century, coronectomy or intentional partial odontectomy was introduced into the oral surgical field from prosthodontics. This procedure has been proven to be effective in terms of safety, practicality, and complication rate after years of research and clinical application. This article aims to provide new insights into the practice of exodontia of the mandibular third molar by making a comprehensive review of coronectomy.

Key words: mandibular third molar, coronectomy, inferior alveolar nerve, residual root
