目的：对比高速涡轮气钻法与凿骨劈冠法拔除下颌水平埋伏阻生智齿的临床疗效。方法：回顾分析口腔门诊120颗低位水平阻生智齿患者的临床资料，其中采用传统的凿骨劈冠法拔除60颗为锤凿组，采用高速涡轮气钻拔除60颗为涡轮钻组，对2组手术时间及术中、术后并发症发生情况进行观察和对比分析。结果：涡轮钻组拔牙时间短于锤凿组，差异有统计学意义（ P＜0．05）。涡轮钻组术中邻牙损伤、下齿槽神经损伤和下颌角骨折的发生率以及术后颊面部的肿胀、疼痛程度、张口受限程度和干槽症的发生率均低于锤凿组，差异均有统计学意义（P＜0．05）。结论：采用高速涡轮气钻法拔除水平埋伏阻生齿能明显缩短手术时间，减少术中、术后并发症的发生，比传统的凿骨劈冠法具有明显的优越性，值得在临床推广应用。

Objective:To compare the clinical effects of high -speed air turbine drill and traditional chisel on removal of impacted mandible third molars .Methods:The clinical datas of the patients with 120 lower impacted mandible third molar were retrospectively analyzed .In witch high-speed air drill group(60) and chisel group(60)to be performed tooth extraction by high -speed air drill and traditional chisel osteotomy respectively .Then the duration of extraction and the intraoperative and postoperative complications were observed and recorded to assess the two methods .Results:The duration of extraction of drill group was shorter than chisel extraction group , which had statisti-cal differences between the two groups (P<0.05).The drill group had less postoperative complication such as ache , swelling, limited opening of mouth than those of the chisel extraction group (P<0.05).Occurrence of the inferior alveolar nerve injury , mandibular fracture , adjacent tooth damage and dry sock were lower than chisel extraction group (P<0.05).Conclusions:High-speed air tutbine drill with its evident superiority to traditional chisel , when applied in the extraction of low impacted teeth , can efficiently cut down duration of extraction , reduce the incidence of the intraoperative and postoperative complication and is therefore recommendable in clinical practice .
