上颌骨的

The changes have important effect on the stability of the treatment and the function of mastication.

通过牵引成骨和正畸联合矫治严重上颌后缩后，上颌骨的前移和牙齿的移动必然使上下牙的排列和咬合发生变化，而这种变化对疗效的稳定性和患者的咀嚼功能的恢复有着重要影响。

This constriction occurs at the boundary of the premaxilla and the maxilla in the upper jaw.

这收缩发生在边界premaxilla和上颌骨的上颌骨。

Results The position of the maxilla after orthopedics was significantly advanced (P .001), but there was still difference from normal values.

结果治疗后上颌骨的位置前移变化有显著性(P＜0.01)，但与正常值之问也存在一些差异。

Objective To analyse the biomechanical effects of stress distribution on the maxilla reconstructed by free fibula composite flap.

目的 对游离腓骨复合组织瓣重建上颌骨进行生物力学研究，了解重建上颌骨的承力情况及应力分布。

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。

Fossils unearthed in northern China mainly in Hebei, Shanxi, Beijing Zhoukoudian and other places, mainly in the northwest Gansu and Shaanxi Province. In 1998, the Gansu Provincial Museum in Guanghe buyers Lane, collected two specimens of saber-toothed tiger, a jaw to bring a complete skull, to take another bite of mandibular complete skull.

出土化石的地点主要在华北的河北、山西、北京周口店等地，西北则主要在甘肃和陕西省境内。1998年，甘肃省博物馆在广河买家巷，征集到两件剑齿虎标本，一件为带上颌骨的完整头骨，另一件为带上下颌骨咬合的完整头骨。

It is concluded:①The method does not traumatize the periosteum of the hard palate,thus alleviating postoperative maxillary deformity;②The buccal musculomucosal flap is generally long enough to reach across the incisive foramen and maintain good blood circulation;③The method benefits reconstruction of the levator sling and facilitates velopharyngeal closure.

该方法有以下优点：①手术不剥离硬腭区粘骨膜，对上颌骨的损伤很小，减轻了上颌骨的发育障碍；②采用两块带蒂颊粘膜肌瓣重建了腭帆提肌功能，促使异位的提肌悬吊再形成；③血运良好的颊粘膜肌瓣插入于软硬腭交界处，能使软腭充分后退，实现腭咽闭合，而且可有效地防止瘘孔的发生。

Biomechanical evaluation and functional design of the maxillary reconstruction method using the microsurgery fibula graft and Branemark zygoma implant were studied.

利用Branemark颧骨种植体，结合显微外科骨移植技术重建半侧缺损和全缺损上颌骨的形态和功能，并对重建的生物力学效果进行评价。

In this research, the pubertal five-week-old SD rats were chose as experimental object to establish the animal model for simulating maxillary protraction, on which was imposed the orthopedic force of 85g with utilizing the self-devised maxillary protraction appliance. Located lateral X-ray cephalograms were taken to measure and analyze the changes of maxillary development after exerting the orthopedic force for 4 weeks. The technique of immunohistochemistry was used to investigate theexpression of TGF-, in frontomaxillary sutures and palatomaxillary sutures with identical force performing for different extent of time. The average hue was selected as indicator, which was measured by the means of the analysis system of pathological color images. The measuring data were analyzed by the one-way ANOVA in software SPSS 11.0 version.

本研究采用自行设计的上颌前牵引装置，以生长发育期5周龄SD大鼠为实验对象，施加85g的矫形力，建立了模拟上颌前牵引的动物模型，通过X线头影测量分析，观察施力4周后上颌骨的生长发育情况；应用免疫组织化学技术，检测同一力值作用不同时段下TGF-β_1在上颌骨的额颌缝、腭颌缝的表达，彩色病理图象分析系统测定每张切片中阳性染色细胞的平均灰度值，结果采用SPSS 11.0进行方差分析。

Results Of the 48 successful cases,after 3～36 months following-up,bilateral high lip equal,bows and restore the natural shape and function of the upper lip,for a fractured alveolar ridge gradually converging on the jaw and the development of satisfactory results.

结果 本组48例患者，术后随访3 月～3年，双侧唇高相等、唇弓形态自然并恢复了上唇的功能，促进了牙槽嵴裂隙的逐渐靠拢和上颌骨的发育，效果满意。
