摘　　要：目的评价高速涡轮钻法拔除下颌中、低位阻生智齿的临床可行性及其优越性。方法作者对369颗下颌阻生智齿随机采用凿骨劈冠术(对照组)或高速涡轮钻法(实验组)去除阻力两种拔除方法,进行临床观察分析,记录患者张口受限程度、疼痛程度及干槽症的发病情况。结果实验组手术时间明显比对照组手术时间短,差异有统计学意义(P<0.05)。两组患者疼痛程度和张口受限程度的构成比差异有统计学意义(P<0.05)。两组干槽症的发病率差异有统计学意义(P<0.05),实验组发病率明显低于对照组。结论高速涡轮钻法能显著缩短手术时间,减轻患者术后的疼痛、张口受限、干槽症等不良反应,值得临床推荐。Objective To evaluate the feasibility and safety of using high-speed air-turbine drill to extract medium and low impacted mandibular third molars. Methods 369 cases were randomly divided into control group and experiment group. Tra- ditional hammer chisel splitting method was used in the control group and high-speed air-turbine drill in the experiment group. Lim- ited mouth opening, postoperative pain and dry sockets were observed. Results The duration of tooth extraction in the experiment group is significantly shorter than that in the control group（ P 〈 0. 05 ）. The pain score and limited mouth opening between the two groups demonstrated significant difference（P 〈0. 05）. Also postoperative complications such as dry sockets is obviously lower in the experiment group（P 〈 0. 05 ）. Conclusion The high-speed air-turbine drill shows obvious advantages in the extraction of low and medium impacted mandibular third molars with statistic significance.
