摘　　要：目的:探讨Twin Block和隐适美矫治器双期矫治对安氏Ⅱ1类患者的矫治结果,为该方案临床应用提供依据。方法:选取1例下颌后缩伴牙列拥挤的患者,诊断为安氏Ⅱ1类错[牙合]畸形,毛氏Ⅱ2+Ⅳ1+Ⅰ1类错[牙合]畸形,结合文献复习探讨该矫治方法的治疗效果。结果:应用Twin Block和隐适美矫治器行双期矫治,测量患者治疗前后的头颅定位侧位片、牙弓长度及宽度,比较矫治前后测量值;分析患者治疗前后的Ricketts审美平面变化。与矫治前比较,矫治后患者SNB角增大1.7°,ANB角减小0.7°,L1/MP角增大8°,U1/L1角减小6°;U1-NA距减小,L1-NB距增大;上颌牙弓中段宽度增加3.8 mm,下颌牙弓后段宽度增加3.4 mm;上下颌牙弓长度亦有所增加。Ricketts审美平面分析,矫治后颏部前移。结论:对安氏Ⅱ1类患者行Twin Block和隐适美矫治器双期矫治,可改善患者侧貌,在达到治疗目的的同时给患者带来良好的矫治体验。Objective:To explore the orthodontic results of two-phase treatment of Twin Block appliance and Invisalign appliance in thePatient with Angle classⅡdivison 1 malocclusion,and toProvide the basis for the treatment in clinics.Methods:APatient with mandibular retraction accompanied by crowdedness,who was diagnosed as Angle classⅡdivison 1 malocclusion,MaoⅡ2+Ⅳ1+Ⅰ1 malocclusion was selected,and the curative effect of this method was discussed combined with the literature review.Results:Twin Block appliance and Invisalign appliance were applied for two-phase treatment,then the lateral cephalometric radiograph,the lengths and widths of the dental arches were measured and the measurement values were compared between before and after treatment;the changes of Ricketts estheticPlanes of thePatient before and after treatment were analyzed.Compared with before treatment,the angle SNB was increased by 1.7°,the angle ANB was decreased by 0.7°,the angle of L1/MP was increased by 8°,and the angle of U1/L1 was decreased by 6°;the distance of U1-NA was increased,while the distance of L1-NB was decreased;the width of middle maxillary dental arch was increased by 3.8 mm,the width ofPosterior mandibilular dental arch was increased by 3.4 mm,and the lengths of maxillary and mandibilular dental arches were also increased.The results of Ricketts estheticPlane analysis showed thePosition ofPogonion moved forward after treatment.Conclusion:Twin Block appliance and Invisalign appliance as two-phase treatment can be used for thePatients with Angle classⅡdivison 1 malocclusion,and it can improve the facialProfile ofPatient;the method can achieve the therapeuticPurpose while bringing excellent orthodontic experience to thePatients.
