摘　　要：目的:对比上颌垫矫治器采用3种不同弓丝制作双曲舌簧矫治乳牙反的临床效果。方法:选择该院口腔科就诊的乳前牙反的病例60例,分为3组,各20例。分别应用直径为0.016"澳丝、0.018"澳丝、0.5mm不锈钢丝弯治双曲舌簧制作矫治器,比较3组病例矫治完成时间及矫治器在加力后的固位情况。结果:矫治完成时间为0.018"澳丝组矫治最短,其次为0.016"澳丝组,0.5mm不锈钢丝组最长。0.018"澳丝组矫治器最易出现弹起现象。结论:应用0.018"澳丝制作双曲舌簧矫治效率最高。Objective To compare the efficacy of the maxillary occlusal pad appliance using three archwire making hyperbolic reed correction deciduous anterior crossbite correction,and determine an appropriate interceptive orthodontics strategy of deciduous anterior crossbite. Methods 60 cases with deciduous anterior crossbite from dental department of our hospital were randomly divided into 3 groups with 20 patients in each group, namely wire diameter of 0.016 inches Australia wire,0.018 inches Australia wire,0.5mm stainless steel wire bent hyperbolic reed.The main outcome measures were complete treatment time and after the afterburner appliance retention situation. Results Complete treatment time of 0.018 inches Australia wire group was the shortest,followed by 0.016 inches Australia wire group, and 0.5mm stainless steel wire was the longest.However,the bounce phenomenon was easily occurred in the 0.018 inch Australian wire group patients. Conclusion Application of 0,018 inch Australian wire bent Hyperbolic reed achieves the highest efficiency.
