目的应用Mini Uni-Twin (MUT)托槽按Begg矫治技术理念矫治安氏Ⅱ1错(牙合)畸形,评估其临床矫治效果并初步探讨其矫治机制.方法选取16例安氏Ⅱ1错(牙合)畸形患者,拔除4个第一前磨牙,应用MUT托槽早期结合Begg矫治理念和后期应用直丝弓技术进行矫治,对治疗前后的头影测量项目进行统计分析.结果 16例患者的平均疗程为(16.3±2.6)月.治疗后U1-SN角减小17.94°,U1-NA和L1-NB距离分别减小6.83 mm和1.98 mm,前牙覆(牙合)和覆盖分别减小1.94 mm和6.84 mm,治疗前后差异有统计学意义(P＜0.001).结论应用MUT托槽结合Begg矫治技术的理念可高效应用于安氏Ⅱ1错(牙合)畸形的矫治.

Objective To assess the clinical effects of Mini Uni-Twin(MUT) brackets in treating Angle Ⅱ1 malocclusion with the theory of Begg technology and to explore the treatment mechanics.Methods 16 patients with Angle Ⅱ1 malocclusion were extracted 4 first premolars and treated with MUT Brackets,combining Begg technology in the early stage and Edgewise technology in the late stage.The results of cephalometric measurements before and after treatment were statistically analyzed.Results The average treatment time was 16.3 months.After treatment,U1-SN decreased by 17.94°,U1-NA decreased by 6.83 mm,L1-NB decreased by 1.98 mm,overbite decreased by 1.94 mm and overjet decreased by 6.84 mrn.All 5 measurements were different from pre-treatment significantly(P＜0.001).Conclusions MUT brackets can be effectively used in treating Angle Ⅱ 1 malocclusion with the theory of Begg technology.
