Total maxilla setback by Le Fort Ⅰ osteotomy is an effective way to cure the patients of maxillary prognathism with skeletal Class Ⅱ malocclusion.

对于骨性Ⅱ类上颌骨前突畸形患者，Le Fort Ⅰ型骨切开上颌骨整体后退术是一种安全、合理、有效的正颌外科术式。

Objective To observe and evaluate the profile changes after maxillary protraction treatment for Class Ⅲ malocclusion.

目的 观察与评价上颌前方牵引矫治器矫治骨性Ⅲ类错后软组织侧貌的变化。

The maxillary protraction with orthopedic force is often used to treat those with the primary deformity of maxilla underdevelopment.

其中，以上颌骨发育不足为主要畸形表现的患者，临床常采用矫形力牵引上颌骨向前进行矫治。

At the same time, on the base of self-developing 3-D finite element models of craniofacial complex, this article explores the change rule of stress、 strain and displacement of craniofacial complex against different strength and direction of maxillary protraction.

同时在自主建立的颅面复合体三维有限元模型基础上，探讨了不同大小和方向的前牵引力对整个颅面复合体的应力、应变和位移变化规律，以期达到为临床力系统选择提供科学依据的目的。

ObjectiveTo determine the rule of simulated protraction and palate expansion on shift of maxillary bone,and to supply the scientific data for treating maxilla in patients with cleft lip and palate.

在自主探索建立的唇腭裂上颌骨三维有限元模型的基础上，利用ANSYS 10.0软件模拟上颌前牵引和上颌扩弓，分析比较前牵引力作用下上颌骨的位移变化。

Three vertical pillars (canine, zygomatic and pterygoid) could be observed, and the stresses in the wall of maxillary sinus was first described in this study.

本模型的建立为上颌骨在咀嚼力、冲击力、矫形力等多种力系作用下的生物力学行为的数值分析提供了良好的方法，并为今后最终建立全颅颌面骨组织有限元模型提供了基础。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
