摘　　要：目的:评价舌侧楔形分牙法在微创拔除下颌水平阻生第三磨牙中的临床效果。方法:选择172例行下颌水平阻生第三磨牙拔除术的患者,随机分为2组,每组86例。试验组采用舌侧楔形分牙法,常规组采用传统T形分牙法。对2组患者的手术时间、术后反应及并发症分别进行比较,采用SPSS 26.0软件包对数据进行统计学处理。结果:试验组的拔牙时长显著短于常规组(P<0.05);试验组舌侧骨板损伤、断根率、术后肿胀及疼痛均小于常规组,差异有统计学意义(P<0.05)。结论:使用舌侧楔形分牙法拔除下颌水平阻生第三磨牙,可以缩短手术时间,保护舌侧骨板,减少断根发生,并能够减轻术后肿胀、疼痛等反应。PURPOSE:To investigate the effect of lingual wedge shaped coronectomy in extraction of horizontally impacted mandibular third molar(HIMTM).METHODS:A total of 172 patients with HIMTM were randomly divided into experimental group and routine group with 86 cases in each group.Lingual wedge-shaped coronectomy was applied in the experimental group and T-shaped coronectomy was applied in routine group.Operation time,intraoperative and postoperative complications were compared between the two groups.The data were analyzed by using SPSS 26.0 software package.RESULTS:The operation time of the experimental group was significantly shorter than that of the control group(P<0.05).The rate of swelling,pain,lingual bone plate injury and broken root of the experimental group were separately lower than that of the control group,and the difference was statistically significant(P<0.05).CONCLUSIONS:Lingual wedge shaped coronectomy of HIMTM has significant advantages in the extraction of HIMTM.It can reduce operation time,broken roots,fracture of lingual plate,postoperative swelling,pain and other surgical complications.
