摘　　要：目的:研究正畸牵引拔除下颌低位阻生第三磨牙对患者张口受限情况的影响。方法:选取2019年10月至2020年10月在我院就诊的下颌低位阻生第三磨牙患者126例,根据治疗方式不同分为对照组和研究组,各63例。对照组给予常规拔牙治疗,研究组给予正畸牵引拔除。统计正畸治疗前、拔牙前、拔牙后1周两组患者张口受限、疼痛、肿胀程度以及近中、远中牙槽骨密度。结果:研究组拔牙前、拔牙后1周张口受限、疼痛评分均低于对照组拔牙前、拔牙后1周(P<0.05)。研究组拔牙前、拔牙后1周张口受限、疼痛评分低于正畸治疗前;拔牙后1周张口受限、疼痛评分低于拔牙前(P<0.05)。研究组拔牙后1周张口受限程度0度高于对照组,Ⅰ度低于对照组;疼痛程度-高于对照组,++低于对照组;肿胀程度-高于对照组,+低于对照组(P<0.05)。研究组拔牙前、拔牙后1周远中、近中牙槽骨密度均高于对照组拔牙前、拔牙后1周(P<0.05)。研究组拔牙前、拔牙后1周远中、近中牙槽骨密度高于正畸治疗前;拔牙后1周远中、近中牙槽骨密度高于拔牙前(P<0.05)。结论:正畸牵引拔除下颌低位阻生第三磨牙能改善患者张口受限情况,缓解患者疼痛,减轻患者软组织肿胀程度,改善患者牙槽骨密度,促进患者恢复。Objective:To study the effect of orthodontic traction in removing the impacted lower mandibular third molar on the patient's mouth opening restriction.Methods:Totally 126 patients with low mandibular impacted third molars who were treated in our hospital from October 2019 to October 2020 were selected.According to different treatment methods,they were divided into a control group and a study group with 63 cases each.The control group was treated with conventional tooth extraction,and the study group was treated with orthodontic traction.Statistics were recorded of mouth opening,pain,swelling,and mesial and distal alveolar bone density of the two groups of patients before orthodontic treatment,before tooth extraction,and 1 week after tooth extraction.Results:The mouth opening limitation and pain scores of the study group before and 1 week after tooth extraction were lower than those of the control group before and 1 week after tooth extraction(P<0.05).In the study group,the mouth opening limitation and pain score before and 1 week after tooth extraction were lower than those before orthodontic treatment;the mouth opening limitation and pain score 1 week after tooth extraction were lower than those before tooth extraction(P<0.05).One week after tooth extraction,the degree of mouth opening limitation of the study group was 0 degree higher than that of the control group,I degree lower than that of the control group;the degree of pain-higher than that of the control group,++lower than that of the control group;the degree of swelling-higher than that of the control group,+lower than that of the control group(P<0.05).The bone mineral density of distal and mesial alveolar in the study group before and 1 week after tooth extraction was higher than that in the control group before and 1 week after tooth extraction(P<0.05).In the study group,the bone mineral density of distal and mesial alveolar before and 1 week after tooth extraction was higher than that before orthodontic treatment;the bone mineral density of distal and
