摘要/Abstract

摘要： 拔除下颌第三磨牙(mandibular third molars,MTM)后继发的下牙槽神经损伤(inferior alveolar nerve injuries,IANI)损伤是较为常见的并发症(0.35%~8.4%),可造成暂时性或永久性的神经损伤。目前已经提出了几种减少或消除这种并发症的方法,例如正畸牵引辅助拔牙、截冠留根术(或称冠切除术)等,这一系列病例的目的是提出一种无风险或低风险拔除与下牙槽神经(inferior alveolar nerve,IAN)密切接触的下颌第三磨牙的新方法。本文将介绍一种去除近中冠阻力待余留牙根尖远离下牙槽神经管后拔除的病例,探讨该方法的应用价值。

Abstract: Inferior alveolar nerve injury secondary to extraction of the mandibular third molars (MTM) is a common complication (0.35% to 8.4%) and can cause temporary or permanent nerve damage. Several methods have been proposed to reduce or eliminate this complication, such as orthodontic traction-assisted tooth extraction, crown amputation and root retention, etc. The purpose of these series of cases is to extract mandibular third molars that are in close contact with the inferior alveolar nerve with no or low risk. In this article, we will introduce a case of extraction such molars after removing the eruption of tooth with proximal coronary resistance, and discuss the application value of this method.

Key words: inferior alveolar nerve injury, impacted mandibular third molar, removal of mesial coronary resistance, coronectomy
