下颌骨

Objective: To investigate the characteristics of mandibular fracture.

目的：探讨下颌骨骨折的特点。

Objective: To evaluate the accuracy of measurement of Ⅱ° furcation involvements in molars of dry mandibles by cone-beam computed tomography.

目的：评价锥形束CT对离体干下颌骨磨牙Ⅱ°根分叉病变测量的准确性。

AIM: To investigate the influence of gallium salts on the bone metabolism of mandibular osteoporosis rats caused by tretinoin.

目的： 研究镓盐对维甲酸引起的下颌骨骨质疏松大鼠骨代谢的影响。

The classic example is the ear ossicles of mammals, which we know from palaeontological and embryological studies originated in the upper and lower jaws and the hyoid of their Synapsid ancestors, and further back still were part of the gill arches of early fish.

典型的例子是哺乳动物的听小骨。我们从古生物学和胚胎学研究了解到，哺乳动物的听小骨起源于它们单弓型祖先的上下颌骨和舌骨，再往前则是早期鱼的鳃弓的一部分。

Mandibular segmental defect or asymmetry due to congenital or acquired factors will lead to severe functional incapacitation and facial deformity .

由于先天或后天的一些因素，导致下颌骨部分缺损或不对称，而这种缺损或不对称常常导致严重的功能丧失和颜面畸形。

METHODS: Immunohistochemistry was applied to investigate RANKL protein expression in incisor teeth.

每只小鼠均取其下颌骨，应用免疫组织化学染色的方法进行小鼠切牙破骨细胞分化因子蛋白染色。

AIM: To analyze the distribution of initial stress around screw implant.

目的：分析螺旋形种植体植入下颌骨后骨界面初始应力的分布。

PURPOSE: To assess the clinical effect of intermaxillary traction titanium screw on complicated mandibular fracture.

目的：评价骨内颌间牵引钛钉在复杂下颌骨骨折中应用的临床效果。

The intermaxillary traction titanium screw could reduce the time of operation, and shows high efficiency in fixation of mandibular fracture.

骨内颌间牵引钛钉能缩短手术复位操作时间，对下颌骨的整复固定和功能恢复效果良好。

Methods: 63 cases with mandibular fractures were treated with open reduction, and then internal fixation were managed with intermaxillary fixation using dental arch splint or intermaxillary fixation screw randomly.

对63例下颌骨骨折切开复位内固定的患者随机采用牙弓夹板或颌间结扎钉进行颌间牵引固定，比较操作时间、治疗后牙周指数、张口度、咬合关系及骨折愈合情况。

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。
