微种植体支抗推磨牙远中移动的临床研究作者:***来源:《中国美容医学》2021年第10期[摘要]目的:探究微种植体支抗推磨牙远中移动矫治安氏Ⅱ类错牙合畸形的临床疗效。
方法:回顾性分析2016年1月-2018年12月于笔者医院接受传统口外弓支抗治疗(对照组,n=60)及接受微种植体支抗治疗(研究组,n=60)的安氏Ⅱ类的错牙合畸形患者的临床资料。
对比两组矫治时间,计算两组牙冠、牙根远移值[上颌第一磨牙牙冠平均远中移动值(UM1E-Y)、上颌第二磨牙牙冠平均远中移动值(UM2E-Y)、第一磨牙牙根平均远移值(UM1A-Y)、第一磨牙牙根平均远移值(UM2A-Y)],比较两组治疗前后的其他牙齿相关指标[上颌第一磨牙近中颊尖点至Y轴的距离(U6-Y)、上颌第一磨牙牙根尖点至Y轴的距离(U6a-Y)、上颌中切牙长轴与SN平面夹角(U1-SN)]、硬组织指标[上齿、下齿槽座角(SNA、SNB)、上下齿槽座角(ANB)、牙合平面与SN平面夹角(OP-SN)]、软组织相关指标[上唇突度、下唇突度、鼻唇角(NLA)、上唇突距(Ls-E)]及咀嚼功能(咬合力、咀嚼效率)的差异。
结果:研究组平均矫治时间显著短于对照组(P0.05),而对照组较治疗前显著降低(P0.05),而OP-SN较治疗前上升(P0.05),而研究组OP-SN显著低于对照组(P[关键词]安氏Ⅱ类错牙合畸形;微种植体支抗;磨牙远移;咬合功能[中图分类号]R783.5 [文献标志码]A [文章编号]1008-6455(2021)10-0157-04Clinical Study on Micro-Implant Anchorage for Molar DistalizationCHEN Xu-dao(Department of Stomatology,Dazhou Integrated TCM &Western Medicine Hospital,Dazhou 635000, Sichuan, China)Abstract:Objective To explore the clinical efficacy of micro-implant anchorage for molar distalization in correcting Angle Class Ⅱmalocclusion. Methods A retrospective analysis was performed on clinical data of patients with Angle Class Ⅱ malocclusion who received traditional headgear anchorage treatment (control group, n=60) or received micro-implant anchorage treatment (study group, n=60)in our hospital from January 2016 to December 2018. The correction time was combined between the two groups, and the crown and root distalization values [average distalization value of maxillary first molar crown (UM1E-Y), average distalization value of maxillary second molar crown (UM2E-Y), average distalization value of first molar root (UM1A-Y), average distalization value of second molar root (UM2A-Y)] were calculated in the two groups. The tooth-related indicators [the distance from maxillary first molar mesiobuccal tip to Y axis (U6-Y), the distance from maxillary first molar root apex tip to Y axis (U6a-Y),angle between the long axis of maxillary central incisor and the SN plane (U1-SN)], hard tissue indicators [sella-nasion-A point, sella-nasion-B point (SNA, SNB), A point-nasion-B point (ANB), occlusal plane-SN plane angle (OP-SN)], soft tissue-related indicators [upper lip protrusion (Ls-SnPg), lower lip protrusion (Li-SnPg), nasolabial angle (NLA), upper lip protrusion distance (Ls-E)] and masticatory function (occlusal force, masticatory efficiency) before and after treatment were compared between the two groups. Results The average correction time in study group was significantly shorter than that in control group (P0.05), andU1-SN in control group was significantly lower than that before treatment (P0.05), and OP-SN was higher than that before treatment (P0.05), and OP-SN in study group was significantly lower than that in control group (PKey words: Angle ClassⅡ malocclusion; micro-implant anchorage; molar distalization; occlusal function安氏Ⅱ类错牙合畸形可分为1、2两个分类,其中安氏Ⅱ类1分类错牙合畸形在我国青少年人群恒牙期的患病率约20%,不仅影响患者牙齿咀嚼功能、牙列整齐,也会影响其面貌美观,不利于患者身心健康[1]。

【摘要】无托槽隐形矫治器在推上颌磨牙远中移动方面具有显著优势。
但由于上颌解剖结构不同及患者依从性差异等因素,上颌磨牙远中移动的实际移动量与设计移动量间存在一定差异,影响最终矫治效果。
该文就患者基本情况、上颌磨牙及周围解剖结构、方案设计方面进行综述,以期为正畸医生设计上颌磨牙远移方案提供参考依据,并提高远移实现效率。
