摘要

在齒顎矯正治療時，常常利用拔牙的方式讓前牙往後方移動，而這樣的移動是否會影響舌頭的運動及功能則有待驗證；本研究的目的是使用B+M模式口腔超音波防震掃描技術，去評估接受拔牙治療之矯正患者，在前牙後退完成之後，舌頭吞嚥運動的時間和振幅是否會改變，並檢測前牙距離、角度的改變比率和舌頭吞嚥運動改變比率之間的相關性。以13位符合條件的志願者為受測對象，分別在前牙退後之前後各取一次測顱X光片及超音波吞嚥之影像資料；而後以測顱X光片描繪取得前牙距離、角度的改變比率，另以電腦輔助分析超音波吞嚥影像，得到舌頭吞嚥各分期的時間振幅之改變比率，再進行統計分析。結果顯示，在矯正治療完成前牙後退之後，舌頭吞嚥各分期的持續時間與振幅皆沒有改變；因此可證明，舌頭本身對矯正治療後牙弓型態及齒列空間的變化，具有相當程度的適應能力。

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. The subject consisted of four men and nine women, with a mean age of 21.3 years old. The subjects were undergoing orthodontic treatment with extraction, and there were at least 3mm space left on each side between lateral incisors and canines. The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction. 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.
