It is also found the rest position of tongue is highly positive related to the magnitude of phase Ⅱa and phase Ⅲa. It demonstrated that anterior teeth retraction would not affect tongue movement during swallowing.

结果显示，在矫正治疗完成前牙后退之后，舌头吞咽各分期的持续时间与振幅皆没有改变；因此可证明，舌头本身对矫正治疗后牙弓型态及齿列空间的变化，具有相当程度的适应能力。

The purpose of this study was to evaluate the changes on the tongue movement during swallowing before and after orthodontic retraction of anterior teeth using ultrasound technique.
