不同牙冠切割法拔除阻生牙的临床效果

Clinical effects of the removal of impacted teeth with different crown cutting method

目的探讨两种不同牙冠切割方案对拔除阻生牙的临床疗效。方法选取我院2016年3月至2017年5月收治智齿阻生患者200例,随机分为高速涡轮钻组(n=100)和传统凿击组(n=100),分别给予高速涡轮钻法治疗和传统凿击法治疗。观察两组患者术后肿胀程度、张口受限、疼痛程度以及术后并发症的情况。结果高速涡轮钻组肿胀程度[(13.3±2.2)mm],张口受限[(4.6±1.4)mm]、疼痛评分[(5.5±2.7)分]、术后并发症总发生率(16.0%)均优于传统凿击组[(16.5±1.7)mm,(9.5±2.6)mm,(8.6±3.4)分,30.0%](P<0.05)。结论与传统凿击法相比,高速涡轮钻法在拔除阻生牙的治疗上具有较高的安全性和显著的疗效。

Objective To investigate the clinical effects of two methods in removal of impacted teeth.Methods Two hundreds patients who had impacted teeth in our hospital from March 2016 to May 2017 were enrolled in this study and randomly divided into high speed turbine group(n=100)and traditional chisel group(n=100),which were treated with high speed turbine drilling method and traditional chisel method respectively.The degree of swelling,the limitation of mouth opening,the degree of pain and the postoperative complications were observed in both groups.Results In high speed turbine group,the degree of swelling was(13.3±2.2)mm,the limitation of mouth opening was(4.6±1.4)mm,the pain score was(5.5±2.7)and the total incidence of postoperative complications was 16.0%,which were better than those in the traditional chisel group[(16.5±1.7)mm,(9.5±2.6)mm,(8.6±3.4)and 30.0%](P<0.05).Conclusion Compared with traditional chisel method,the high speed turbine drilling method has higher safety and better curative effect in the treatment of impacted teeth extraction.
