查询词典 maxillary

Results maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years). this inclination increased with age. the logistic regression showed that the sagittal inclination of the first molar is a predictor of the eruption of the third molar.

结果 上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。logistic回归结果显示第一磨牙的轴倾度是第三磨牙萌出的一个预测因子。

The three maxillary molars at the experimental sides were moved as one unit mesially by a Sentalloy coil spring delivering a force of 10 cN over a long range of activation. The contra-lateral molars served as controls. At 1, 2, 4, 8, and 12 weeks groups of animals were killed for histological evaluation.

实验侧的三颗磨牙用结扎丝颌粘接剂固为一个整体，在超弹性拉簧作用下（力值为0.1牛顿）向切牙侧移动。l， 2， 4， 8和12周时给予大鼠过量麻醉剂，材料用于组织学研究。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。
