下颌骨

The operation procedures include amputation of the mandibular ramus of the affected side, shaking and fracturing of the affected condyloid process, exsomation and reshaping it, reduction and reconstruction of the TMJ.

手术是作下颌骨患侧的升枝部截断，再将病变的髁状突摇摆松动折断，摘下离体进行修整成形后，再予以复位重建关节。

In conclusion, during the different periods after surgery, the stress distribution of bilateral condyloid processes are dissymmetrical obviously: the stress of affected condyloid process become largen more obviously than that of unaffected one, and it is the most possible in the sixth month after surgery that TMD would befallen.

本实验结论：在本实验条件下，下颌骨体部缺损游离髂骨块移植三种连接方式不同时期，双侧髁突表面应力分布不对称：患侧髁突前后斜面压拉应力明显增高且高于健侧，其中以术后6月时最明显。

Results:Fractures in body,angle and ascending branch of mandible could be showed fine by all these imaging methods. 3D-CT was better than 2D-CT and conventional X-ray plain film in diagnosis of fractures in condyle and coronoid process. Conventional X-ray plain film was poor in diagnosis of the maxillary fractures.2D-CT and 3D-CT were similar in diagnosis of the maxillary fractures.3D-CT showed the jaws fractures directly and stereoscopicly.

结果：对于下颌骨体部、角部和升支骨折，三种影像学都能很好的显示，对于髁状突和喙突骨折，三维CT检查优于常规X线和二维CT；常规X线显示上颌骨骨折较差，而二维CT和三维CT显示的准确性比较接近。

Patients were examinated and evaluated by cephalometric analysis and polysomnographic data. Three cases were treated by temporomandibular joint reconstruction with costochondral graft. Five cases underwent external distraction osteogenesis.

以术前术后的cephalometry和polysomnography数据作分析。3个病人用肋软骨重建颞下颔关节，5个用下颔骨骼牵引术，1个用下颌骨前进术。

Costochondral graft (cartilage 3-5mm long) reconstruction of the mandibular condyle in the growing goats results in a nearly normal new coodyle, which can maintain normal development of the mandible. Supported by Shanghai Leading Academic Discipline Project.

保留关节盘的自体CCG（软骨长度3~5mm）重建生长期山羊下颌髁突后，能够改建成接近正常髁突的形态，并维持该侧下颌骨的同步生长发育。

Objective:To observe the differences of bone mineral density of mandible and coxofemoral region between well-rounded ridge group and atrophied ridge group in edentulous patients,and to find the risk factors contributing to severe residual ridge resorption.

目的：观察无牙颌患者剩余牙槽嵴丰满组与非丰满组间下颌骨和髋部骨密度的差别；探讨导致严重剩余牙槽嵴吸收的危险因素。

PURPOSE: To evaluate the curative effect of titanium compression miniplate internal fixation and craniomaxillary elastic traction in single mandibular fracture.

目的：评估小型加压钛板内固定加颅颌牵引复位技术治疗下颌骨单发性骨折的临床效果。

Mandibles devitalized by freezing and boiling after being removed from animals were reimplanted to evaluate their potentials of reunion and growth with X-ray and histologi-cal methods.

本文通过动物实验，采用X线片和组织学检查方法观察比较冷冻和煮沸自体下颌骨再植术后的骨愈合过程。

The branches from its first branch to anterior bel ly of digastric muscle has a length of is 13.07±2.49mm.

从下颌骨下缘向前行至第一次分支为第二段，其长度为13.61±3.09mm，直径为1.21±0 。14mm。

Results Dismountable 3-D finite element model of mandible with denture is estab lished.

结果得到具有可拆卸性、多用途的下颌骨及下牙列的三维有限元模型。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
