查询词典 incisor

In clinic, lingual and labial orthodontics have many differences, especially the torque control of the upper incisor.

临床上，舌侧正畸和唇侧正畸相比，力学机制有很多不同；上切牙的转矩控制更是舌侧正畸中的难点。

Relatively small gnawing animals having a single pair of constantly growing incisor teeth specialized for gnawing.

相对小的啮齿动物，有一对适于啃咬的不停生长的门牙。

Results 12 single lower incisor absence patients, of whom 6 combined with tooth extraction;3 used interproximal enamel stripping and the rest 3 combined with prosthetics;16 double lower incisors absence patients,of whom 10 combined with tooth-extraction and the rest 6 combined with prosthetics.

结果：12例单个下切牙先天缺失患者中，有6例结合减数矫治，3例采用邻面去釉技术，3例结合修复方法；16例两个下切牙先天缺失患者中，10例减数矫治，6例采取缺牙修复。

In lingual orthodontics, the applying of intrusion force was less useful than the well control of the M/F ratio to control the torque of upper incisors. If the crown of the incisor had been inclined lingually, it would be very difficult to recover the torque.

3舌侧正畸中，首要的是控制好M/F值，否则即使加大垂直压低力也难以抵抗冠唇向转矩的不足；而且一旦产生舌倾趋势，将比唇侧正畸更难以恢复。

METHODS: Measurement of palatal raphe area first three-dimensional reconstruction of images at up to nasion plane centerline, whichever was determined as a reference surface plane, selection one point on incisor cervix in this line, to measurement of the available palatal bone height; sagittal views were selected at 6 mm dorsally from the incisive canal. The available bone height was defined as the distance from the palatal baseline (lower cortical border of the palate) to the nasal cavity (upper cortical border of the nasal cavity).

先在三维重建图像上以鼻根为准确定面中线平面为参考平面，在此线上选择1个位于中切牙牙颈部的点，在其矢状位图像上，选取位于口腔内侧骨皮质上距切牙孔后缘6 mm处为标测点，通过此点向硬腭做垂线确定腭骨厚度，测量范围自口腔内腭部骨皮质外侧边缘至鼻腔侧骨皮质外侧边缘。

This study concludes that the first erupted permanent tooth in Taiwanese children is either mandibular incisor or mandibular molar.

本研究显示，恒牙第一大臼齿及下颚门牙有相同的机会成为第一颗萌发出来之恒牙。

RESULTS: RANKL immunostaining was strong positive in the root of incisor teeth.

结果：切牙牙根周围核因子κB受体活化剂配体蛋白染色强阳性。

Absence of one incisor or one canine, a third premolar or a fourth premolar or of one molar.

缺一个门齿或犬齿，第三前臼齿或第四前臼齿或一个臼齿。

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

Result:One case originated from the supernumerary teeth on the floor of left nasal cavity, and the other left reversed lateral incisor.

结果：1例起源于左鼻腔底额外牙的含牙囊肿，另1例起源于左鼻腔底倒生侧切牙的含牙囊肿，均有同侧上唇、鼻旁的反复肿胀史。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
