摘　　要：目的:比较电动式颌面微动力系统和高速气动外科手机在下颌低位阻生智齿拔除术中的应用效果。方法:将133例下颌低位阻生智齿随机分成2组,分别使用电动式颌面微动力系统和高速气动外科手机进行手术,比较2组间拔牙时间和术后肿胀、疼痛、张口受限、干槽症、神经损伤、邻牙损伤情况,结果采用SPSS19.0软件包进行统计学分析。结果:电动式颌面微动力组的手术时间明显少于高速气动外科手机组,术后肿胀、疼痛、张口受限程度明显小于高速气动外科手机组(P<0.05),干槽症、神经损伤发生率低于高速气动外科手机组,但差异无统计学意义。结论:应用电动式颌面微动力系统拔除下颌低位阻生智齿具有良好的临床效果。Objective：To compare the effects of electric micro-dynamic systems and high-speed air-turbine drill in the extraction of mandibular deeply impacted wisdom teeth,and to evaluate the advantages and short comings of each method.Methods：One hundred and thirty-three cases of mandibular deeply impacted wisdom teeth were randomly assigned to two groups：one group was extracted by using electric micro-dynamic systems（MDS Group）,while the other was treated by using high-speed air-turbine drill（HST Group）.Then the duration of operation,postoperative pain,swelling,trismus and the rate of dry socket,inferior alveolar nerve（IAN）injury,and damage to adjacent teeth were compared.The data were statistically analyzed with SPSS19.0software package.Results：The data showed that the duration of operation of MDS group was shorter than HST group significantly.The occurrence of postoperative pain,swelling and trismus of MDS group was fewer than that of HST group statistically（P〈0.05）.The incidence rate of dry socket and IAN injury of MDS group was lower than that of HST group,but no statistical difference be found.Conclusion：Compared with high-speed air-turbine drill,electric micro-dynamic systems can obtain better clinical effect by cutting down duration of operation with minor wound and reducing the incidence of postoperative complications efficiently.
