摘要： 目的 比较掺铒钇铝石榴（Erbium Yttrium-Aluminum-Garnet，Er：YAG）激光和超声骨刀去除下颌低位垂直阻生齿骨阻力的临床疗效，以探寻拔除此类牙的选最佳方法。
方法 60例符合纳入条件的患者随机分为Er：YAG激光去骨组和超声骨刀去骨组，观察比较2组患者的手术时间，术后疼痛、面部肿胀、张口受限程度及患者满意度。
结果  Er：YAG激光去骨组患者在术后第1、3、7天的疼痛程度，以及术后第3、7天面部肿胀、张口受限的程度均高于超声骨刀去骨组，两者差异无统计学意义（P＞0.05）。但超声骨刀去骨组的手术时间明显更短，患者满意度更高。
结论 在拔除下颌低位垂直阻生齿时采用Er：YAG激光和超声骨刀去除骨阻力，2组患者的术后并发症差别不大，但超声骨刀的效率更高，患者更为满意。

Abstract: ObjectiveTo compare the clinical effect of Erbium Yttrium-Aluminum-Garnet(Er：YAG) laser and piezosurgery(PS) in removing the bone resistance of low vertically impacted mandibular third molars, and to explore the optimal method for extraction of such teeth. 
MethodsA total of 60 eligible patients were randomly divided into two groups for osteotomy: Er：YAG laser group and PS group. The duration of operation, postoperative pain, facial edema, trismus and patient satisfaction were compared between the two groups. 
ResultsThe postoperative pain at 1, 3, and 7 d after surgery，and facial edema and trismus at 3 and 7 d after surgery were slightly higher in Er：YAG laser group than in PS group, suggesting no significant difference. However, the duration of operation was significantly shorter and the patient satisfaction was higher in PS group. 
ConclusionIn the extraction of low vertically impacted mandibular third molars, the postoperative complications between Er：YAG laser and PS groups are similar, but PS is more efficient and obtains more patient satisfaction.
