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。

In Angle's Class II,division 1 patients, the upper incisors labially inclined and closed up the upper lip,the lower lip reduced the covering with the upper incisors' crown.

安氏II类1分类错唇齿关系形态特征表现为：上中切牙明显唇倾并与上唇过度贴合，上唇外翻，下唇对上中切牙覆盖明显减少。

The proportion of maxillary center incisors, maxillary lateral incisors, maxillary canines curved in mesiodistal were 11.17%, 16.19% and 21.43%, in labio-lingual were 39.59%, 40.00% and 29.59%, both in labiolingual and mesiedistal directions were 4.60%, 35.24% and 24.49%.

Maxillary central incisors had a slightly greater pulpal blood flow values than maxillary lateral incisors. The flow values from 15 teeth with necrotic pulp or pulpless teeth were significantly lower than that from the control teeth. Before therapy the values from 16 deep caries teeth were all higher than that from the control teeth. After therapy, most (15/16) of those values decreased to normal in three days. The value of one tooth with deep caries remained high, and one week later, the pulp became necrosis.

由死髓牙测得的流量值显著小于正常对照。16颗深龋患牙治疗前牙髓血流量皆高于正常对照组，治疗后有15颗患牙的血流量很快降至正常，有1颗患牙在治疗后血流量无明显变化，最终发生牙髓坏死。

The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。

Its mechanism is downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors and the forward growth of maxilla.

FR-Ⅲ是矫治替牙期前牙反的理想方法之一，其机理是下颌骨向下、向后旋转，舌倾下切牙，唇倾上前牙，促进上颌骨向前生长。

Secondly, the incisors grow faster, then the beginning of next to no longer permanent, in the "free" environment will, of course, a large growth, but within the next two years to grow permanent incisors on the natural limits; the most important point is that "parents feel that the incisors are the wrong impression", after the permanent teeth will not grow up stereotypes, so on the child's little face, mouth does not match, it appears to "Super", as the children grow up day by day face, bone development, facial development, such as children and adults will face the size of incisors is coordination of the match,"So we say that time will the children from 'ugly duckling' change 'Swan'."

其次，门牙长得快，这时旁边的恒牙都没开始长，在&无拘无束&的环境下当然会生长得大一点，但两年内旁边恒牙长出就自然限制了门牙；最重要的一点是，&觉得门牙大都是家长的错觉&，恒牙定型后不会再长大，所以放在孩子的小脸、小嘴中不匹配，才显得&超级大&，随着孩子脸形一天天长大，骨头发育、面部发展，等孩子成年时门牙就会和脸形大小十分协调、般配了，&所以我们说时间会让孩子由'丑小鸭'变'天鹅'&。
