摘　　要：目的:比较超声骨刀微创拔牙法与传统拔牙法拔除下颌水平阻生智牙的临床效果。方法:将240例下颌阻生智牙患者随机分为微创拔牙组及传统拔牙组,每组120例。比较2组手术时间、术中并发症(包括术中根折、拔牙窝形变)发生情况、术中心理畏惧情况、术后并发症(包括干槽症、开口受限、面颊部疼痛、肿胀)、术后下唇及舌部麻木症状的发生情况。采用SPSS 13.0软件包对数据进行统计学分析。结果:微创拔牙组和传统拔牙组手术时间分别为(18.0±6.3)min和(37.0±8.2)min,存在显著差异(P<0.05)。微创拔牙组拔牙窝中、重度形变发生率及术中心理畏惧发生率均显著低于传统拔牙组(P<0.05),术后第3天开口受限程度与术后疼痛肿胀发生率与传统拔牙组相比,均有显著差异(P<0.05)。结论:超声骨刀微创拔牙法拔除下颌阻生牙较传统拔牙法手术时间短,术中、术后并发症少,患者心理畏惧程度较低,可显著降低对拔牙窝及邻牙的创伤,患者更愿意接受,适宜在临床上推广应用。PURPOSE:To compare the clinical effect of using piezosurgery device and traditional method in extraction of horizontally impacted mandibular third molar.METHODS:Two hundred and forty patients with horizontally impacted mandibular third molar were equally divided into 2 groups:using piezosurgery device and traditional method for extraction.The operation time,intraoperative and postoperative complications including deformation of extraction sockets,dry socket,limitation of mouth opening,pain and swelling,and fear were observed and compared between the two groups.The data were analyzed with SPSS 13.0 software package.RESULTS:The operation time was(18.0±6.3)min in the minimally invasive extraction group,significantly shorter than the traditional method group which was(37.0±8.2)min(P<0.05);significant difference was found in the incidence of medium or severe tooth sockets deformation and incidence of psychological fear during operation between the two groups(P<0.05);the degree of mouth opening after surgery,the incidence of moderate or severe pain after surgery was significantly lower in the group with piezosurgery device than in the group with traditional method(P<0.05).CONCLUSIONS:Minimally invasive extraction with piezosurgery device is better than traditional method in extraction of horizontally impacted mandibular third molar,with shorter operation time and fewer intraoperative and postoperative complications,which should be widely applied in clinic.
