| 摘 要： | 阻生下颌第三磨牙拔除是口腔颌面外科的一种常见手术.由于低位阻生的下颌第三磨牙牙根位置常与下牙槽神经(inferior alveolar nerve,IAN)关系密切,神经损伤是该手术的严重并发症之一.目前,国际上主要有3种避免IAN损伤的方法:截冠法、部分牙冠切除术和正畸牵引法.本文报告1例下颌第三磨牙近中斜位低位阻生的患者,采用改良正畸牵引法,分两步将牙根牵离神经管,牵引完成后顺利拔除患牙.

| Abstract: | Extraction of impacted lower third molar is a common procedure. Damage of the inferior alveolar nerve （IAN） is one of the severe complications, in that the roots of the tooth are often close to the nerve canal when it is impacted at a low position. There arc mainly three approaches： coronectomy, partial odontoectomy and orthodontic extraction to minimize neurological risks. A case of mesioangular impacted third molar treated with improved orthodontic extraction was reported in this paper. The orthodontic treatment consisted 2 stages, up-righting and extrusion.
