下颌骨

Methods:The steps and procedures for making the clasp retained cyst plug was introduced,and it was used in 5 cases of odontogenic mandibular cysts following marsupialization.

介绍了囊肿塞的制作、戴入后处理及5例下颌骨牙源性囊肿的临床应用。

Results: 1 Intense ERα immunoreactivity localized in the hypertrophic and maturative layer, and some immunoreactivity was found in osteoblasts of mandible and temporal bone, while no immunoreactivity was found in the disc and synovium. 2 The expression of ERα in male rats TMJ cartilage was higher than that in female ones. 3 In the condyle cartilage of male rats, the density of ERα positive cells decreased with age, which kept stable after 16 weeks of age. 4 In the condyle cartilage of male rats, the density of ERα positive cells was stable from birth to 8 weeks, but decreased from 16 weeks to 12 months, while the density in 18-month group recovered to the level of 8 weeks. Conclusion: TMJ is one of target organs of estrogen, and ERα plays an important role in the effect of estrogen on TMJ.

结果：1TMJ中ERα主要在髁突软骨的肥大层和过渡层表达，下颌骨和颞骨的骨细胞也有少量表达，而关节盘、滑膜中几乎无表达；2雄性SD大鼠髁突软骨中ERα的表达明显强于同龄的雌性大鼠；3在雄性大鼠TMJ髁突软骨中阳性细胞密度随年龄增长逐渐降低，16周以后逐渐维持在相对稳定的水平；4雌性大鼠从出生后到8周龄阳性细胞密度基本稳定，在16周龄至12月龄年龄组阳性细胞密度显著降低，而在18月龄后又恢复到8周龄以前的水平。

OBJECTIVE: To assess the value of mandibular distraction osteogenesis in treatment of OSAS in patients with congenital micrognathia and the effect of the surgery on the patients' respiratory functions.

目的：探讨和评价下颌骨牵引成骨技术在治疗小下颌畸形伴OSAS中的应用价值及对呼吸功能的改善作用。

Reported the first clinical application of mandibular lengthening by gradual distraction in patients with hemifacial microsomia and Nagers'syndrome.

自从1992年，McCarthy等首先报道采用下颌骨逐渐牵引延长，以治疗半面萎缩和Nagers综合征以来，颌面部牵引成骨技术的研究已陆续开展起来。

Methods The surgery included both osteotomy and Medpor transplantation as a large scale filling stuff transfer under periosteum for hemifical microsomia(3 cases) and simple mandibular hypoplasia (6 cases) reco...

截骨并以Medpor作为填充材料，进行多部位，大范围组合填充于骨膜下骨与肌肉之间，矫治半侧颅面矮小 3例，单纯性下颌骨发育不良 6例。

Methods The surgery included both osteotomy and Medpor transplantation as a large scale filling stuff transfer under periosteum for hemi fical microsomia(3 cases) and simple mandibular hypoplasia (6 cases) reconstructi on. Results The result was satisfactory and showed a good nature skeleton facial outline.

方法截骨并以Medpor作为填充材料，进行多部位，大范围组合填充于骨膜下骨与肌肉之间，矫治半侧颅面矮小3 例，单纯性下颌骨发育不良6例。

Objective: To study the change of mandibles with age of Taihang Macaca mulatta, providing information for the physical and medical experiment with Macaca mulatta.

目的：探讨太行山猕猴下颌骨随年龄变化的形态学改变，为太行山猕猴的体质学、医学实验、进一步确定其分类地位提供可靠的依据。

After three dimension measurements,neoformative callus underwent HE staining and three points bending test.

对双侧兔下颌骨新生骨痂进行外径测量、苏木精伊红染色及生物力学测试。

Taken together, these findings suggest that Bmp-4, Shh and Wnt-5a gene expressions may act together on the epithelial-mesenchymal interactions occurring in several aspects of the early mouse craniofacial development, such as odontogenesis, neuronal development, maxillae and mandible ossification, palatogenesis and tongue formation.

综上所述，这些研究结果表明，骨形态发生蛋白4， Shh和Wnt信号- 5A型基因表达共同作用，对早期小鼠颅面部的发育中上皮间的相互作用产生很大影响，如牙齿的发育，神经发展，上颌骨和下颌骨骨化及舌头的形成。

In order to get good result based on the different cases, the right procedures (ostectomy, masseter excision or buccal fat pad removed) should be chose carefully.

劈裂截骨术对下颌骨体肥大伴明显外翻者可取得相当好的手术效果，手术结合部分咬肌及颊脂肪垫的去除能取得更为理想的效果。

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。
