广西医科大学学报JOURNALOFGUANGXIMEDICALUNIVERSITY2023Jan；40（1）种植钉辅助二次矫治高角患者上牙列远移的临床研究*林佳锐，韦佳黛，徐若君，樊雪敏，莫水学△（广西医科大学附属口腔医院，南宁530021）摘要目的：探讨二次矫治高角患者使用种植钉远移上牙列的牙齿与后平面位置变化。方法：回顾性分析14例二次矫治的安氏Ⅱ类一分类高角患者，收集治疗前、后的头颅侧位片进行测量分析。结果：治疗后患者SN-MP角、OP-P角、U1-SN角、U1-NA距、U6C-Y距、U1C-Y距、U1A-Y距、U6-PP距、UL-EP距、LL-EP距均减小（P＜0.05）。矫治后上牙列整体远移，磨牙压低，后平面逆时针旋转，上下唇突度减小。所有患者均达到预期矫治目标。结论：种植钉不仅能够有效远移上牙列，而且能使后平面发生逆时针旋转，有利于改善二次矫治高角患者侧貌。关键词二次矫治；种植钉；上牙列远移；后平面中图分类号：R783.5文献标志码：A文章编号：1005-930X（2023）01-0121-05DOI：10.16190/j.cnki.45-1211/r.2023.01.019ClinicalstudyofthemaxillarydentitiondistalizationinorthodonticretreatmentpatientswithhyperdivergentmalocclusionbyminiscrewLinJiarui,WeiJiadai,XuRuojun,FanXuemin,MoShuixue.(HospitalofStomatology,GuangxiMedicalUniver-sity,Nanning530021,China)AbstractObjective:Toanalyzetheteethandposteriorocclusalplanechangesinretreatmentpatientswithhy-perdivergentmalocclusionbyminiscrew.Methods:14AngleclassⅡdivision1orthodonticretreatmentpatientswithhyperdivergentmalocclusionwereretrospectivelystudied.Lateralcranialradiographsbeforeandaftertreat-mentwerecollectedformeasurementandanalysis.Results:Aftertreatment,SN-MP,OP-P,U1-SN,U1-NA,U6C-Y,U1C-Y,U1A-Y,U6-PP,UL-EP,LL-EPdecreased(P＜0.05);themaxillarydentitionwasdistalized,themolarwasdepressed,theposteriorocclusionplanerotatedcounterclockwise,andtheupperandlowerlippromi-nencewasreduced.Allpatientsachievedtheexpectedorthodonticgoals.Conclusion:Theminiscrewcannoton-lyeffectivelydistalizethemaxillarydentition,butalsomaketheposteriorocclusionplanerotatecounterclock-wise,whichisconducivetoimprovingtheprofileoforthodonticretreatmentpatientswithhyperdivergentmaloc-clusion.Keywordsretreatment;miniscrew;maxillarydentitiondistalizati...
