這就是RPE,像不像小螃蟹,若要看相關的文章,請鍵入RPE 就可以找到一些文章來看,它就是

1)在上顎雙邊的第一小臼齒與第一大臼齒裝上BAND(帶環)

2)中間的部份是以JACKSCREW擴大旋轉鈕連接,中間有箭頭往喉側轉

3)年青族群以每天早晚各轉一次(1/4圈)為宜

4)成年族群以每天轉一次為宜

5)採用過度矯正(OVERCORRECTION)為準則,可以達2-3mm

6)維持時間(retention)3-6個月,screw的中間以流動樹脂覆蓋住行固定

7)每轉一次為0.25mm

8)最大的擴張容許度為 10~12mm

 有關於RPE擴張後上下顎的整體骨體變化為:

1)occlusal plane(咬合面):楔形分開(前寬後窄)

2)frontal view(正面):金字塔形擴開(pyramid)

3)sagittal view(矢狀面):向下向前打開咬合

4)上顎suture(縫)的打開量約等於左右牙弓擴張量的一半

5)上顎齒槽突向外擴張

6)錨定牙(anchorage tooth)向頰側傾斜

7)整個incisal cycle 約為4個月

8)上顏面(N-ANS)與下顏面高度(ANS-Me)增加

9)下顎向下向後旋轉

由研究顯示,青春期前使用RPE確可刺激midpalatal suture的生長

RPE的適應症(indications):

1)青春期病人

2)橫向空間不足者(>4mm)

3)單側或是雙側後牙反咬(crossbite)

4)前後空間不足者

5)上顎發育不足合併顎裂者

6)上呼吸道狹窄(respiratory constriction)

RPE的不適應症(contraindications):

1)前牙開咬(open bite),下顎平面太陡峭合併外觀太突出者

2)上下顎骨頭明顯不對稱者(jaw bone deformity)
