The results are as follows:(1) With the imposing of orthopedic force of simulating maxillary protraction on maxilla, in the sagittal direction, the maxillary complex of the SD Rats in experimental group grows more quickly than that in two control groups, and the extent of the maxillary complex increases more evidently. The maxillary complex displays anti-clockwise forward and upward rotation.(2) With the imposing of orthopedic force on maxilla, upper incisors exhibit labial-inclined, labioclination of lower incisors changes insignificantly, and the shape and the dimension of skull are not affected significantly.(3) The expression of TGF-3 , in frontomaxillary sutures and palatomaxillary sutures shows different intensity in different extent of time. But The expression of TGF-{3, in experimental group is more intensive than that in two control groups, and that in operated control group and natural growth group has no significant difference.

结果如下：在模拟上颌前牵引矫形力作用下，(1)生长发育期大鼠上颌复合体在矢状方向生长加快，长度明显增加，并表现出向前向上的逆时针旋转；(2)上切牙唇倾，下切牙的唇倾度没有明显变化，颅脑的形态与大小不受影响；(3)额颌缝和腭颌缝中TGF-β_1的表达，同一时段实验加力组要强于手术对照组与自然生长组，而手术对照组与自然生长组之间无显著性差异。
