摘　　要：目的对比传统的凿骨劈冠法和改良涡轮机拔除法拔除下颌阻生第三磨牙时的临床效果,评价改良涡轮机拔除法的可行性和优越性。方法选择500例下颌阻生第三磨牙病例,其中260例(实验组)使用改良涡轮机拔除,另240例(对照组)用传统凿骨劈冠法拔除,对手术时间、术后并发症进行分析观察和统计分析。结果实验组手术时间明显比对照组短(P<0.05),两组患者术后疼痛程度和张口受限程度的构成比存在明显性差异(P<0.05),两组干槽症的发生率有显著性差异(P<0.05),实验组明显低。结论改良器械的使用,使阻生下颌第三磨牙的拔除时间缩短,并发症减少,值得推广使用。Objective To compare the clinical effects of traditional chisel method and high-speed air turbine drill method of extrac- ting impacted mandibular wisdom teeth, and to evaluate the clinical feasibility and superiority of the high-speed air turbine drill method. Methods 500 patients with impacted mandibular third molars were randomly divided into 2 groups：test group and control group. 260 cases （test group） used the high-speed air turbine drill and new instruments to extract the impacted mandibular third molars while other 240 cases （control group） used the bone chiseling and dental crown hacking method to extract the impacted mandibular third molars. The operation time and post-operative complications were observed and recorded to evaluate the effects of the two methods. Results The data showed that the operation time of the test group was obviously shorter than the control group （P 〈 0.05） . There was signifi- cant difference in the degree of pain and limitation of mouth opening degree （ P 〈 0. 05） after the operation between two groups. The in- cidence of alveolalgia of the test group was apparently lower than that of the control group, Conclusions The high-speed air turbine drill and new instruments method of extracting impacted mandibular wisdom teeth can efficiently shorten the operation time,reduce the incidence of complications, so it is worthy to be promoted and widely used.
