摘要： 近中阻生下颌第三磨牙拔除是口腔外科常见手术。中、低位近中阻生的第三磨牙牙根与牙根位置常与下牙槽神经(inferior alveolar nerve, IAN)关系密切,由于近中邻牙的阻力,拔除时创伤较大,易造成第二磨牙损伤及神经损伤。本文报告1例牙根压迫下牙槽神经的近中阻生下颌第三磨牙患者,采用微创正畸牵引法,直立患牙,牵引完成后顺利拔除。

Abstract: Extraction of impacted lower third molar is a common procedure. Damage to 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. For mesioangular impacted lower third molar, the adjacent second molar is likely to be injured accidentally during extraction. A case of mesioangular impacted lower third molar with its roots close to the inferior alveolar nerve canal treated with minimally invasive orthodontic assisted extraction was reported in this paper. The purpose of the orthodontic treatment was to upright the third molar to simplify the procedure of extraction, and to reduce postoperative complications.

Key words: Impacted third molar, Mesioangular impaction, Inferior alveolar nerve, Orthodontic-assisted extraction, Minimally invasive surgery
