The spring inclined plane is one of the removable appliances that can be used to correct incisors crossbite which is designed for the early treatment period. In order to prevent skeletal malocclusion and reestablish proper muscle balance. The appliance is very simple which composes of clasps on the first molar both sides and spring 0.9 millimetre diameter. This spring was bended as an inclined plane above the lower incisors. The force from this spring will push upper incisors anteriorly. The spring inclined plane is very effective in mixed dentition. Nevertheless this spring is appropriate to use in the patient who can not wear the removeable orthodontic appliance in the upper jaw.
弹簧斜面矫治器是可用于矫治前牙反合的活动矫治器之一，设计用于早期治疗阶段。为了预防骨性错合并重建适当的肌肉平衡。该矫治器非常简单，由两侧第一磨牙上的卡环和直径0.9毫米的弹簧组成。这个弹簧在下前牙上方弯成一个斜面。这个弹簧产生的力会将上前牙向前推。弹簧斜面矫治器在混合牙列期非常有效。然而，这种弹簧适用于不能佩戴上颌活动正畸矫治器的患者。
