查询词典 mesially

Methods:7 cases of classⅡ,division 1 maloclusion were treated.Upper first premolar and lower second premolars were extracted in all cases.Lower first molars were mesially moved by means of segmental arch. Cephalometric analysis was used to evaluate the effects of the treatment.

应用片段弓技术对7例安氏Ⅱ类1分类患者，通过拔除上颌第一前磨牙及下颌第二前磨牙，使下颌第一磨牙较快地向近中移动，纠正磨牙Ⅱ类错牙合关系。

Upper first molar moved 4.14mm distally, and the upper incisors moved 0.66mm mesially.

上颌第一磨牙向远中平均移动4.14mm，上颌中切牙向唇侧移动0.66mm。

When the proportion of force to moment is 1∶4.7, the canine will translational move distally. To reinforce anchorage with second molar can prevent anchorage teeth movement mesially during canine distal movement.

要使尖牙平行远中移动，远中牵引力与力矩的最佳比例为 1∶4.7；将第二双尖牙、第一、第二磨牙连成整体，可减小尖牙远中移动时的支抗消耗。

The fluorescent bands formed in both mesial and distal cementum.Conclusion The results don't support the point that transseptal fibre or force of molar eruption makes teeth migrate mesially; the mesial migration of teeth is related with the reconstruction of alveolar bones and the stress distribution in the bones.

实验结果不支持越隔纤维作用或磨牙萌出力作用引起牙齿近中移动的观点；牙齿近中移动与颌骨内应力分布有关，牙槽骨改建的量与牙齿近中移动量呈正相关。

Upper and lower incisor both had controlled tipping movement. The crown of incisor moved mesially and had root apex were fixed relatively. The center of rotation was close to root apex. The upper and lower molar moved differently.

结果：唇挡治疗后，SNA、SNB分别增加1.02°和0.97°(P.05)，上下切牙前移均是牙冠向近中倾斜，而根尖相对固定的控制性倾斜，旋转中心接近根尖。

Anchorage loss measured at the first premolar averaged 1.3 mm,but the crowns tipped 3.5?distally.During distalization with Distal jet,the first premolar did not tend to tip mesially as found in many investigation of other intraoral distalizing appliance.

每侧第一前磨牙的支抗丧失平均为1.3mm并伴3.5 的牙冠远中倾斜，这一结果不同于其它口内磨牙远移装置所造成的前磨牙牙冠近中倾斜，与国外对同类矫治器的观察结果相似。

After 4~8 months, in adult bimaxillary protrusion patients, cuspids were moved to distal, the upper first molars were moved 1.12mm mesially evenly, and the upper incisors were moved 7.91mm palatelly evenly.

成人双颌前突患者在4～8个月后远移尖牙到位，拔牙间隙基本关闭，上颌第一磨牙为近中整体前移，其冠部平均前移了1.12mm，上颌切牙冠部平均向腭侧倾斜移动约7.91mm。

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。

A case report was presented with a female patient of class II malocclusion, bimaxillary dentoalveolar protrusion with space deficiency. Bilateral lower left second molars were mesially inclined impactions with large caries. The lower left second molar was diagnosed with acute apical periodontitis.

本文提出一双颚齿槽前突合并齿列拥挤之安格氏二级咬合不正之女性患者，其下颚两侧第二大臼齿为近心倾倒之阻生齿合并龋齿，而左下第二大臼齿之龋齿已侵犯到牙髓而有急性根尖牙周炎的情况。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
