摘　　要：目的:比较拔除下颌阻生第三磨牙时,传统的凿骨劈冠法与改良涡轮机拔除法的优劣。方法:600例下颌阻生第三磨牙病例,其中300例,使用传统的凿骨劈冠法拔除,另300例使用改良涡轮机法拔除,对手术时间以及术中、术后并发症进行对比观察和统计分析。结果:2种方法的手术时间分别为(22.285±12.025)min和(16.115±12.078)min。与传统的凿骨劈冠法相比,改良涡轮机拔除法拔除下颌阻生第三磨牙的手术时间较短(P<0.05),术中及术后并发症的发生率均明显降低(P<0.05)。结论:改良器械的应用,使阻生下颌第三磨牙的拔除更加方便,值得推广应用。Objective：To study the feasibility of extraction of impacted mandibular wisdom teeth using turbine drill and new instruments.Methods： 600 patients with impacted mandibular third molars were divides into 2 groups.A group used turbine drill and new instruments to extract the impacted mandibular third molar.B group used the dental chisel to extract the impacted mandibular third molar.The operation time,intraoperative and postoperative complications were recorded to assess the effects of the methods.Results： The operation time of group A and group B was（22.285±12.025 01） min and（16.115±12.078 62） min respectively.The operation time of group A was shorter（P0.05）.The intraoperative and postoperative complication incidence rate was lower（P0.05）.Conclusion： Turbine drill and new instruments method is superior to dental chisel method in the extraction of impacted mandibular wisdom teeth.
