摘　　要：目的分析单侧Forsus矫治器治疗安氏Ⅱ亚类错畸形患者的临床效果。方法 23例安氏Ⅱ类亚类错患者,在直丝弓固定矫治器排齐整平上下牙列后,患侧单侧戴用Forsus矫治器。同时选择27例未治疗的安氏Ⅱ类亚类错患者作为对照组。在治疗前、治疗后拍摄X线头颅侧位片,分别测量和分析牙齿、骨骼和软组织的各项指标。结果 Forsus矫治器可矫正安氏Ⅱ类亚类错畸形,在矢状方向上后移单侧上颌磨牙并前移单侧下牙列,在水平方向上纠正中线不齐,牙齿移动差异有统计学意义(P<0.05)。结论单侧Forsus矫治器可产生显著的牙齿和软组织改变,能有效治疗安氏Ⅱ类亚类错畸形。Objective To assess the result of treatment in ClassⅡmalocclusion subdivision with unilateral Forsusappliance.Methods23patients with ClassⅡmalocclusion subdivision were selected,who were treated with Straightwire fixed appliance in combination with unilateral Forsus appliances while another27patients were untreated as control group.Lateral cephalographs were taken before and after the comprehensive treatment,and the indicators of dental,skeletal,and soft tissue profile were measured.Results The Forsus appliance can correct ClassⅡmalocclusion subdivision through distalizing the upper teeth and moving the lower teeth mesially.Midline can be corrected at the sametime.There was a statistically significant difference in the amount of tooth movement(P<0.05).Conclusion Forsusappliance is an effective device for treating ClassⅡmalocclusion subdivision,which can induce significant dental andsoft tissue changes.
