摘　　要：目的:评析低位水平下颌阻生第三磨牙应用45°涡轮钻改良拔除术治疗的临床效果。方法:选择64例下颌低位水平阻生第三磨牙患者,依据随机双盲法平均分为2组,其中对照组施以传统三角瓣法和高速涡轮钻拔除;实验组则采取涡轮钻彻底分牙法配合三角切龈拔除第三磨牙。比较2组患者手术时间、术后并发症的差异,采用SPSS20.0软件包对数据进行统计学处理。结果:实验组患者的手术时间显著低于对照组(P<0.05),术后疼痛、肿胀、牙龈撕裂、干槽症与开口受限程度显著轻于对照组(P<0.05),而2组的术后出血发生率无显著差异(P>0.05)。结论:低位下颌水平阻生第三磨牙应用45°反角涡轮钻采用彻底分牙法配合三角切龈拔除,具有手术时间短,术后疼痛、肿胀、牙龈撕裂、干槽症以及开口受限发生率低等优势,相对传统涡轮钻拔牙法疗效可靠,值得临床推广。PURPOSE： To evaluate the clinical usefulness of 45 degree turbine drill in the extraction of lower horizontally impacted mandibular third molar. METHODS： Sixty-four patients with lower horizontally impacted mandibular third molar were randomly divided into 2 groups （n=32）. The control group underwent extraction with the traditional method of triangular flap and high speed turbine drill, while in the experimental group, the impacted tooth was completely divided with triangular gingival cutting to pull out the third molars. The surgical time and postoperative complications were recorded and compared using SPSS 20.0 software package. RESULTS： The operation time of the experimental group was significantly shorter than that of the control group （P〈0.05）, pain, swelling, alveolalgia and limitation of mouth opening were significantly lower than the control group （P〈0.05）, postoperative bleeding was similar in 2 groups （P〉0.05）. CONCLUSIONS： Dividing the impacted teeth completely with triangular gingival cutting is an effective method for extraction of lower horizontally impacted mandibular third molar. It can shorten the operation time, lessen postoperative pain, swelling, gum tearing, alveolalgia and limitation of mouth opening; it is safe and reliable and worth of wide clinical application.
