尖牙

ABSTRACT］ Objective To study the changes of the hard tissue profile after extraction of the first bicuspid in maxillary and second bicuspid in mandible for adolescents with malocclusion.

目的 探讨青春期安氏Ⅱ1类错畸形在拔除上颌第一双尖牙和下颌第二双尖牙矫治后硬组织X线影像变化。

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。

Three of the ten were adult denture crowded patients, the others were adults with bimaxillary protrusion. MAS mini-implant were implanted in 15, 16 and 25, 26 separately. The mini-plants were utilized with the rubber chain, ligature silk to move the cuspid to diatal and to adduct the anterior teeth.

收集武汉大学中南医院口腔正畸科就诊成人牙列重度拥挤患者3例，成人双颌前突患者3例，分别在他们15、16和25、26间各植入一枚MAS微型种植体，利用橡皮链，结扎丝和镍铬弹簧等与微植体相连牵引尖牙向远中移动、内收前牙、防止磨牙支抗丧失。

Methods: Mini-implant was used in ten cases as orthodontics anchorage. Three of the ten were adult denture crowded patients, the others were adults with bimaxillary protrusion. MAS mini-implant were implanted in 15, 16 and 25, 26 separately. The mini-plants were utilized with the rubber chain, ligature silk to move the cuspid to diatal and to adduct the anterior teeth.

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

In all case, centric relationship of canine and 1st molar was obtained, with normal overbite and over-jet of anterior teeth.

全部病例均达到尖牙和磨牙的Ⅰ类关系、牙列整齐、前牙覆覆盖正常。

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。

The color of the maxillary anterior teeth is related to tooth position, the central incisor is the lightest but the canine is the darkest, and the canine is redder, yellower, and has the highest Chroma

上前牙的颜色与牙位有关，中切牙的亮度最大而尖牙最暗且颜色更偏红、偏黄，饱和度也最大

Methods Ten volunteers with experimental premature contact at the first premolar, the first molar and the second molar were asked to clench in CO and their electromyographic activity of the masseters, anterior temporalis and anterior belly of digastric muscles were measured simultaneously.

测定 10名志愿者在正中牙合；左右两侧下颌第一双尖牙、第一磨牙、第二磨牙实验性早接触状态下，嚼肌、颞肌前束及二腹肌前腹肌电活动的积分值与频谱值。

The tissue responses to MTA were compared with that to amalgam. In 16 premolar teeth of dogs (32 roots), the root canals were cleaned, shaped and obturated under ideal condition.

第一部分：MTA倒充填后根尖周组织的愈合反应和非胶原蛋白的表达4只健康杂种犬，双侧下颌第三、第四双尖牙作为实验牙。

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
