高速涡轮钻干磨和湿磨法拔除下颌阻生智齿对比分析

目的比较高速涡轮钻干磨和湿磨法在拔除下颌阻生智齿的术后反应和干槽症的发生率。方法运用自体对照法,选择双侧下颌阻生智齿为Ⅱ类高、中位阻生的患者350例,随机选择一侧为高速涡轮钻干磨法去除牙冠阻力,另一侧为高速涡轮钻湿磨法去除牙冠阻力,统计两组患者拔牙术后反应情况及术后干槽症的发生率。结果两种去冠拔牙法的术后反应情况及干槽症发生率均无显著性差异。结论运用高速涡轮钻干磨法拔除下颌阻生智齿,手术安全且对设备的要求较低,值得推广应用。

Comparative Study of Wet Grinding and Dry Grinding with Turbine Drill Applying in Extraction of Impacted Mandibular Third Molars

Objective To compare the clinical reaction and incidence of dry socket between wet grinding and dry grinding with turbine drill applying in extraction of impacted mandibular third molars.Methods Totally 350 patients with impacted mandibular third molars on both sides,one side were released crown resistance by dry grinding method,on the other side by wet grinding method.Then observed the clinical reaction and incidence of dry socket.Results The data showed that degree of clinical poor reaction and incidence ...
