下颌骨

objective: to investigate the mandibular symmetry in cases of temporomandibular disorders with unilateral mastication.

摘要目的：研究颞下颌关节紊乱病患者偏侧咀嚼与下颌骨对称性的关系。

To analyse stress state of mandible pulled by masticatory muscles.

目的：应用有限元方法分析咀嚼肌牵动的下颌骨应力状态。

It is intended to enhance the use of implants in areas of inferior bone quality and quantity, such as the posterior areas of the maxilla and the mandible.

它的目的是旨在增强种植体在下骨质量和数量方面的利用，比如，上下颌骨后面的区域。

To avoid the influence of head position change and to overlap and compare the changing hard tissue under the skull reference system, this work set up a three-dimensional reference frame, which was based on point"S'"(the median point of the upper rear brim of the anterior wall of pituitary fossa), point"Na"and point"Ba"and of which point"S"is origin. UNISIGHT is used to get the original coordinates of all the landmarks in the MPR phase.

为消除矫治前后患者头位变化的影响，使治疗前后变化的上下颌骨和牙列以相对不变的颅底结构作为参照系统进行影像的重叠和对比，本研究通过头颅内的固有标志点S'，N，Ba三点确定了参考平面，建立了以S'点为原点的测量三维坐标系。

It is also less destructive and has fewer cosmetic complications for midfacial neoplasia in the young.

同时也因为它较少的破坏性和美观上较好的考量，下颌骨摆开法更能符合手术治疗发生於小儿中颜面部肿瘤的要求。

In maxilla, DO has been involved in maxillary advancement, maxillary expansion, maxillary alveolar reconstruction and midfacial and/or cranial distraction.

此外，还有上下颌骨的同时牵引延长、面中部和／或颅骨的牵引等。

Methods There were 86 cases of midfacial fractures treated withdifferent operations in different stages (primary, delayed and secondary stages) according to their conditions.

手术方法主要通过原伤口、冠状切口、眶周小切口及口内切口联合入路，暴露骨折断端，分离后以下颌骨作为参照，在建立良好的咬关系的基础上，恢复和加强眶上颌颧骨复合体三对垂直颅颌支柱及二个水平轴。

Objective:To determine whether effects of active vitamin D deficiency and subsequent alterations of milk contents on tooth and mandible development in sucking pups.

目的：为了检测活性维生素D缺乏及其母乳成分的改变是否影响小鼠下颌骨以及牙齿的发育？

Objective: To study the effect of bone morphogenetic proteins-2 （ad-hBMP-2） gene therapy on mandibular fracture union.

目的研究腺病毒介导的人重组骨形成蛋白-2（ad-hBMP-2）对兔下颌骨骨折愈合的影响。

The results of this study demonstrate that ODI is an efficient index for evaluation of the vertical position of the skeletal Class Ⅲ malocclusion.

ODI值是评价骨性安氏Ⅲ类错上、下颌骨垂直向关系较为有效的指标。

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。
