目的:探讨高速涡轮牙钻在拔除下颌阻生智齿中的临床应用体会。方法:选取2012年8月~2013年8月拔除下颌阻生第三磨牙的患者,采用高速涡轮牙钻辅助拔除作为实验组。与2008年5月-2009年7月采用骨凿辅助拔除阻生第三磨牙患者作为对照组的临床资料进行对比。结果:实验组术后肿胀、张口受限、疼痛程度等均优于对照组,差异有统计学意义(P<0.05)。实验组平均手术时间(27.2±7.3)min,对照组(42.5±10.6)min,差异有统计学意义(P<0.01);实验组出现干槽症4例,对照组出现干槽症21例,差异有统计学意义(P<0.01)。结论:涡轮牙钻辅助下颌阻生智齿的拔除,效果好,术后反应小,不失为一种较好的手术式选择。
Objective: To investigate the clinical application of high-speed turbine dental drill in removing impacted mandibular wisdom teeth. Methods: From August 2012 to August 2013, patients with mandibular impacted third molar were selected and assisted with high-speed turbine dental drill as experimental group. The clinical data of patients with third molars with bone chisel assisted extraction from May 2008 to July 2009 as the control group were compared. Results: The postoperative swelling, limited mouth opening and pain degree in the experimental group were better than those in the control group (P <0.05). In the experimental group, the mean operation time was (27.2 ± 7.3) min and in the control group (42.5 ± 10.6) min, the difference was statistically significant (P <0.01) The difference was statistically significant (P <0.01). Conclusion: The extraction of mandibular impacted wisdom teeth by the turbine dental drill is effective and the postoperative reaction is small, which is a good surgical choice.
