它关于传染病提出数据，创伤，中间的暂时的硬化，脑dysgenesis，大脑瘤，血管的损害，中风，和癫痫的遗传学，代谢和有毒的原因。

The lower first molar moved and rotated to distal, the mesial rotate to buccally and the distal rotate to lingually.

5的移动趋势是袷向伸长，冠向近中根向远中倾斜，冠舌向根颊向转矩，且整体受力较小。

In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

Preformed malleable dental crowns with a side-generic external shape with a plane of symmetry in the facial-lingual direction and/or a plane of symmetry in the mesial-distal direction.

具有在颊舌方向上的对称面和/或近远中方向上的对称面的侧面通用外形的预制的可煅的牙冠。

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。

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.

结果发现，两组的垂直牙根断裂均好发於牙冠严重磨耗（77.4-88.2%）且扁平的牙根（61.8-75.8%）上，以大臼齿的近心牙根发生率最高（64-85.7%），多为颊舌侧走向（91.2-91.9%），且於未根管治疗组别亦发现三例腭侧根断裂，走向为较宽的近远心方向，显示牙根断裂会沿著牙根较宽的方向发生；同时，未经根管治疗而产生垂直牙根断裂的牙齿具有根叉位置较低的现象（61.8%），牙根於比例上有较短小的特徵。

The interdental distance between the mesial groove of the first molars and distal groove of the second molars was measured on the maxillary dental casts. The interdental distances at the end of experimental tooth movement and retention were calculated. The effectuality of retentive appliances was evaluated by comparing the tooth movement distances between the experimental side and control side.

在加力结束后和保持结束后即刻制取上颌石膏模型，测量所有模型的第一磨牙牙合面近中沟与第二磨牙牙合面远中沟的距离，计算加力结束后与保持结束后的距离，比较实验侧与对照侧的牙齿移动距离，评价保持装置的有效性。

Mesial The mesial is the surfaces of the tooth that faces toward the front or midline of the mouth.

这句话我现在就知道tooth 这是牙齿的意思，别的都不会。

Mesial or mesial-buccal roots of the first molars (78%) were the predilection site of vertical root fracture.

长期咀嚼槟榔致反复、长期的过大牙合力与异常方向的牙合力可能是牙根纵裂发生的重要因素。

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。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
