Two-stage placement of a dental implant is a well-established method for restoring a missing anterior tooth; however, replacement of an anterior tooth by using two-stage implant surgery may result in changes in the interdental papilla height and loss of alveolar bone with compromised esthetic results.

两阶段配售牙科种植体是一个行之有效的方法恢复丢失的前牙，但是，更换一个前牙采用两阶段植牙手术可能导致牙间乳头的改变高度和齿槽骨丧失影响美观的效果。

Prehension of the relationship and variation combined with image data conduce to well recognization of this area.

视神经管隆突及颈内动脉隆突与后组筛窦和蝶窦的这种复杂解剖关系及其不对称性，是经鼻前颅底手术损伤视神经管及颈内动脉的根本原因，了解这种解剖关系及其变异，术前结合患者影像学资料，可良好判定此区域结构的解剖关系，防止视神经管及颈内动脉损伤导致的严重并发症。

BACKGROUND: Many patients have preoperative anxiety; therefore,the development of a strong anxiolytic with minimal psychomotorimpairment for premedication may be desirable.

背景：许多术前手术的病人有焦虑症状，因此研究一种术前使用的能减轻焦虑而又对精神运动损伤最轻的药物是很必要的。

Using the distortion-compensated roentgen analysis method, disc height, dorsoventral displacement, and lordosis were measured in 212 unfused segments from 62 patients, on digitized standing radiographs taken before fusion surgery and after a mean follow-up of 7.5 years (range, 4-11 years).

在标准数字化X光片上，比较术前和术后平均7.5年（4－11年）后62个病人212个未融合节段的椎间盘高度、椎体滑脱及脊柱前凸的情况，可变的影响因素如年齡、随访时间的长度、融合水平、融合节段数、融合节段上下方向和手术前后椎管的改变，用重复测量模型进行分析。

In light of the present study's findings, we suggest that the technique of anterior decompression, strut grafting, and anterior instrumentation is an effective method for the treatment of post-traumatic kyphotic deformity and that the success of the technique depends on the time from trauma to operation and the severity of baseline deformity, regardless of the type of instrumentation.

从目前的研究发现来看，我们建议，前路减压支撑性植骨，前路内固定的方法是治疗创伤后驼背畸形的有效手段，而且这一方法的成功取决于从受伤后到手术的时间，原始畸形的严重程度等，但与内固定的类型无关。

This dissertation selects the cortex segmentation, objects motion in 3d reconstruction and presurgery design system as the key research contents, and takes the construction of practical presurgery design system as the ultimate goal.

本论文选取了分割技术中的脑皮层分割、脑肿瘤分割、三维重建中的目标体虚拟移动以及术前设计系统的构建作为研究重点，以构建实用的外科手术术前设计系统作为最终目的。

Using the distortion-compensated roentgen analysis method, disc height, dorsoentral displacement, and lordosis were measured in 212 unfused segments from 62 patients, on digitized standing radiographs taken before fusion surgery and after a mean follow-up of 7.5 years (range, 4-11 years).

在标准数字化X光片上，比较术前和术后平均7.5年（4－11年）后62个病人212个未融合节段的椎间盘高度、椎体滑脱及脊柱前凸的情况，可变的影响因素如年齡、随访时间的长度、融合水平、融合节段数、融合节段上下方向和手术前后椎管的改变，用重复测量模型进行分析。

many layer spiral the CT MPR combine a 3 D-SSD, VR be like can explicit diagnosis Han face bone fracture, can keep view ground understanding Han face bone fracture at 3D stereoscopic space of actual size, appearance position and surroundings structure of dissect relation, and for it clinical treatment provide basis, to Han face bone fracture before the Shu establishment surgical operation project and before the Shu, Shu empress contrast all have importance of instruction function.

多层螺旋CT MPR结合3D-SSD、VR成像能够明确诊断颌面部骨折，可直观地了解颌面部骨折在三维立体空间的实际大小、形态位置及周围结构的解剖关系，并为其临床治疗提供依据，对颌面部骨折术前制定手术方案和术前、术后对比均有重要的指导作用。

Materials And Methods 1, The animal model of Sprague-Dawley rat for maxillary protraction was made in this study, and an appliance based on the principle of protraction headgear was designed and made for maxillary protraction treatment which was hooked over the front of the zygomatic arch ,and a hole was made on the skull in the experimental group rat .

以面具式前牵引矫治器为原理制作特殊的前牵引支架，以外科方法安装支架挂在大鼠颧弓前端，在实验加力组大鼠头颅上打孔，安放挂钩，通过弹性牵引提供支架向前牵引的支抗。2、以该动物模型为基础，选用90只五周龄的Sprague—Dawley健康雌性大鼠作实验动物，随机分到实验加力组、正常对照组、手术对照组。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
