上尖牙

An upper second bicuspid bracket with an additional .5 mm of in-out compensation is provided for the common situation in which upper second bicuspids are smaller than upper first bicuspids.

上第二双尖牙支架额外0.5毫米中的规定进行赔偿的共同情况，即第二bicuspids上小于上颌第一bicuspids 。

But in malocclusion the size of cuspid and bicuspid group was correlated with that of mandibular incisor plus first molar group in the same dental arch.

临床上对错尖牙、双尖牙组的预测不能简单等同于正常。

To begin the months-long process, doctors removed one of Thornton's canine teeth—aka an eyetooth—along with part of the jaw and cut it all down to a shape small enough to replace the cornea.

长达几个月的治疗过程开始了，医生们拔下了桑顿的一颗犬齿——也就是上尖牙，并且取了颌骨的一部分，把颌骨切的足够小，以取代角膜。

It does not matter, and it is normal, I have read a lot of baby teeth so long, on the edge of the front teeth called incisors, incisor had called on the canine

没关系的，是正常的，我看过很多这样长牙的孩子，上门牙边上的叫切牙，切牙过上的叫尖牙

The distance of canine movement was measured on the model using the vernier caliper on 7th,14 th,21st and 28th day, respectively.

在尖牙移动后7、14、21和28 d时，在石膏模型上测量尖牙远中移动的距离，并进行统计学的分析。

Days after the extraction of the first premolars, the upper canines were subjected to coronally orthodontic extrusion movements.

后10天内提取的第一前磨牙，上尖牙受到冠正畸挤压运动。

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。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

The posterior length of the dental arch changed significantly (P.001). The maxillary and mandibular arch shapes didn't change before and after treatment.

结果：上、下牙弓宽度在矫治前、后有显著差异(P.05)；上、下牙弓长度治疗前、后尖牙长度变化不明显，而第一磨牙长度具有显著性差异(P.001)；治疗前、后，上、下牙弓形状无明显变化。

In control group, we use the traditional RME method of utilizing bands on bilateral premolars and molars.

对照组在犬的尖牙和第一磨牙上制作个别带环，按传统方法进行螺旋扩弓器的快速扩弓。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
