摘　　要：目的:分析SUS2矫治器在恒牙早期安氏Ⅱ类错治疗中的疗效及应用特点。方法:选择20例12～15岁以下颌后缩为主的骨性安氏Ⅱ类错患者,应用SUS2与多托槽类固定矫治器联合治疗,对其治疗前后的头颅侧位片进行测量、统计分析。结果:20例患者矫治后侧貌改善明显,覆牙合、覆盖正常,磨牙关系为Ⅰ类。头影测量统计显示ANB、U1/SN、U1-NA、U6-PP、L1-MP、UL-E、OB、OJ在治疗后减小,差异有显著性,SNB、L1/MP、L1-NB、Co-Go、Co-Gn、Go-Po、U1-PP、L6-MP、LL-B'-Pos、在治疗后增大,有显著性差异。MP-SNY、-axis在矫治前后无显著性变化。结论S:US2矫治器与托槽类固定矫治器在恒牙早期骨性安氏Ⅱ类错牙合治疗中联合应用能减小覆牙合、覆盖,矫正磨牙关系,并能较好地改善患者的面型。Objective To analyze the curative effect and characteristics of SUS2 appliance in the orthodontic treatment of Angle II malocclusion at early stage of permanent dentition.Methods 20 cases of skeletal Angle II with mandibular deficiency,aged 12 to 15 years old,were selected.All the patients were treated with the combination of SUS2 appliance and bracket fixed appliance.Lateral cephalogram measurement was carried out before and after treatment,and the results were statistically analyzed.Results 20 patients achieved remarkable improvement in the profiles,normal overbite and overjet in teeth and Class I in molar relationship after treatment.The cephalometric analysis showed that ANB,U1/SN,U1-NA,U6-PP,L1-MP,UL-E,OB,OJ were decreased,while SNB,L1/MP,L1-NB,Co-Go,Co-Gn,Go-Po,U1-PP,L6-MP,LL-B＇-Pos were increased after treatment,both with significant statistical difference.There was no significant change in MP-SN and Y-axis before and after treatment.Conclusion The combination use of SUS2 appliance and fixed appliance can be used efficiently in the orthodontic treatment of Angle II malocclusion at an early stage of permanent dentition because it can reduce overbite and overjet,correct molar relationship and improve the patients＇ facial outline.
