摘要/Abstract

摘要： 目的：采用McNamara 分析法评价改良SUS2矫治器矫治安氏II类错的效果。方法：分别采用改良SUS2矫治器和传统SUS2矫治器治疗共20例安氏Ⅱ类错，对治疗前后头颅侧位定位片采用McNamara分析进行分析比较。结果：改良SUS2组和SUS2组都造成了A点到N-FH垂线距离的减小，分别减小了0.6mm 和0.4mm。Lower 1 horizontal沿FOP分别前移了0.3mm和1.5mm。对于Lower 1 –Apo，则分别前移了0.6mm和2.5mm。结论：改良SUS2矫治器可以取得和传统SUS2矫治器相似的临床效果，但可以将排齐牙列放到前伸下颌之后进行，可以更好地利用患者的生长潜力。

Abstract: Objective: To compare the dentofacial changes produced by refined Sabbagh Universal Spring (SUS2) in late adolescent patients with Class II malocclusion, and quantify them in comparison with patients treated by traditional appliance. Method: The study was carried out on two group Class II patients. McNamara cephalometric analysis was performed on each lateral cephalometric radiograph. Results: The effects of both appliances were dentoalveolar. The refined SUS2 group and traditional group both reduce the distance of A to N-FH, the value is 0.6 and 0.4mm. Lower 1 horizontal to FOP move forward at 0.3 and 1.5mm. As to Lower 1 –Apo, the change of the two group is 0.6 and 2.5mm(P＜0.05) Conclusions: Both appliances corrected Class II discrepancies through dentoalveolar changes; however refined SUS2 appliance can promote mandible forward more early before leveling the teeth as traditional method.

Key words: Sabbagh Universal Spring (SUS2), functional therapy, late adolescence
