摘　　要：目的分析涡轮钻法和凿劈法用于拔除下颌阻生第三磨牙临床效果及并发症。方法中、低位下颌阻生牙共486例随机分成两组，分别采用涡轮钻法（199例）和凿劈法（287例）拔除阻生牙，比较两种方法拔牙花费时间及术后并发症发生情况。结果涡轮机钻法拔除阻生牙时间10-45min，凿劈法拔除阻生牙时间12—90min，组间差异有统计学意义（P〈0．05）；涡轮机钻法和凿劈法拔除下颌阻生牙并发症发生率分别为28．8％及55．1％，两组差异有统计学意义（P〈0．05）。结论涡轮钻法拔除下颌阻生牙较凿劈法时间短，术后并发症减少。Objective To investigate the indication d turbine technique or hammer and chisel techmque remortal of impacted mandibular third molars. Methods 486 impacted mandibular third molars patients were randomly divided into two treatment groups. One group received turbine technigne of 199 cases, while another group received hammer and chisel technique of 287 cases. Both the duration of operation and complications were compared. Results The average duration of the operation with turbine technique was （10 - 45 ）min, while with hammer and chisel technique was （ 12 - 90） min, respectively （ P 〈 0.05 ） in the removal of impacted mandibalar third molars, there were significant differences between two groups. The standardized rate of complication with tubine tehnique was 28. 8% ,while with hammer and clisel technique was 55.1% in the remoral of impacted mandibular third molars. Conclusion Extraction of impacted mandi-bular third molars with air turbine hand piece could reduce complication during operation, and risperidone showed better results. It is worth for clinical use.
