切牙

Objective: To study how the depth and morphology of affected the dentinal stress distribution of the root of maxillary central incisor using three-dimensional-finite-element analysis.

目的：应用三维有限元法研究石英纤维桩的不同外形和深度对上领中切牙桩冠修复后牙根应力分布的影响。

The contractile tension of the masster, digastric and lateral pterygoid muscles varied according to the mandibular position, being greatest when the mandible was opened at an interin- cisal distance of 13mm, protruded 6mm and retrated 1mm.

正常4周龄大鼠嚼肌、二腹肌前腹、翼外肌的最大收缩张力分别位于打开下颌切牙间距离13mm、下颌前伸6mm和下颌后退1mm时。

MAIN OUTCOME MEASURES: The palatal bone thickness and bone thickness density were measured at 6 mm dorsally from the incisive canal.

主要观察指标：口腔内侧骨皮质上距切牙孔后缘6 mm处腭中缝的骨厚度及骨密度。

Premaxillary incisor band, outside front distraction mask, and distraction rubber band were self-made.

自制上切牙带环、外置式前牵引面具、牵引橡皮圈。

During the treatment of skeletal Class ill malocclusion in mixed dentition, the reverse Twinblock could procline the upper incisor, accelerated the development of maxillary and mandibular ramus, and restrained the development of mandibular body. A randomly allocated prospective study was required to fully evaluate the bone efficacy of this appliance.

反向Twinblock矫治器可使上切牙唇倾、位置前移；在治疗期间能促进上颌骨的发育，抑制下颌体的发育，促进下颌升支的增高；反向Twinblock矫治器的对上下颌骨的长期作用有待进一步研究。

Mental canal , which bends backward and upward and outward then opens into mental foramina.

结果 下颌管前端分出同一方向前行的切牙神经管和向后、上、外转弯的颏管。

However, i dont like the laterals, either.

然而，我也不喜欢那两颗侧切牙。

The differences between laterals actually make it look natural and beautiful...

两颗侧切牙之间的差异恰恰使得整体看起来自然逼真！

Methods: 86 patients with maxillary lateral incisor loss were selected and the abutments were prepared routinely.

目的：观察用粘结桥、单端固定桥两种方法联合修复上颌侧切牙缺失的临床效果。

Objective [WT5BZ]To evaluate the position changes of the lower incisors in 18 children from 10 to 13 years old.

目的 研究 10～ 13岁儿童下切牙位置的生长变化。方法未经治疗的儿童 18例，男 6例，女 12例。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
