摘　　要：目的:分析研究唇挡结合无托槽隐形矫治器在上、下颌磨牙远移过程中的疗效。方法:选择2022年1月—2023年12月中国人民解放军陆军第七十三集团军医院90例无托槽隐形矫治器治疗的患者,按照治疗方法分为唇挡组、支抗钉组、无附加装置组3组,各30例,比较各组模型前牙随磨牙远中移动量的改变而发生的应力、位移、唇倾度变化情况。结果:唇挡组与支抗钉组治疗前-前导结束后下磨牙远中移动的距离(M-Po)、下中切牙角(IMPA)、下磨牙远中倾斜角(M-MP)差值无明显统计学意义(P>0.05);而唇挡组与无附件组及支抗钉组与无附件组治疗前-前导结束后差值有统计学意义(P均<0.001)。结论:唇挡结合无托槽隐形矫治器在上、下颌磨牙远移过程中表现出较好的疗效,能够有效促进牙齿的移动和调整,值得在临床实践中推广应用。Objective:To analyze and study the effect of lip block combined with bracket free invisible appliance in the process of distal movement of upper and lower molars.Methods:From January 2022 to December 2023,90 patients treated with invisible appliance without brackets in the 73rd group Military Hospital of the PLA army were selected and divided into three groups according to the treatment method:lip block group,anchorage nail group and no attachment device group,with 30 cases in each group.The changes of stress,displacement and lip inclination of the model anterior teeth with the change of the distal movement of the molar in each group were compared.Results:There was no significant difference in the distance of distal movement(m-po),lower central incisor angle(impa),and distal inclination angle(m-mp)of lower molars between the lip block group and the anchorage nail group before and after the end of the treatment(P>0.05).The difference between the lip block group and the non attachment group and the anchorage nail group and the non attachment group was statistically significant(all P<0.001).Conclusion:Lip block combined with brackets less invisible appliance shows good curative effect in the process of distal movement of upper and lower molars,and can effectively promote the movement and adjustment of teeth,which is worthy of popularization and application in clinical practice.
