下颌骨

Objective The conventional simple angle ostectomy sometimes could not get good result for the cases of overwide facial appearance.To reduce the width of the lower face effectively,the angle-splitting ostectomy hasbeen performed.

目的 下面部过宽采取单纯下颌角截骨有时不能取得理想的效果，正确选择适应证进行下颌骨体劈裂截骨术可取得更好的手术效果。

Results About (20±5)mm in length of the mandible had been achieved by the DOdistraction of osteogen...

结果 下颌骨牵引延长(2 0± 0 。5 )mm ，达到预设值 98%，牵引完成后经 5周固定，新骨完全骨化。

The capacity of repairing bone defect of biodegradable PLA and the efficacy of PLA as a carrier for bone morphogenetic protein are determined with detecting the osteogenetic process.

18只日本大耳白兔，随机分组，在双侧下颌骨体部形成 12 m m× 6 mm的缺损，分别植入聚乳酸-人骨形成蛋白- 2复合物(PL A- rh BMP- 2 )、单纯聚乳酸，于 2、4、8、12周分批处死。

Objective A group of patients with mandibular fractures were retrospectively studied to evaluate the complications and indications for compressive osteosynthesis.

目的 本文通过对一组下颌骨骨折病例的回顾性研究，评价了加压固定的适应症和并发症。

In addition, an obvious depression in the retromandibular region almost always results from either superficial or total parotidectomy.

许多腮腺疾病都须采用浅叶或全叶切除术(superficial or total parotidectomy)治疗，术后下颌骨后区域常会形成一凹陷。

The data came from a male volunteer who had the full dentition、healthy periodontium and normal occlusion relationship.

建立下颌骨的三维有限元模型。选用牙列完整整齐，牙周健康，咬合关系正常的成年男性志愿者1例。

Staining of OPG was localized in osteoblasts cell of the periosteal region after completion of distraction.

目的 研究不同浓度rhBMP-2在不同时间对兔下颌骨牵引成骨区新骨生成的影响及牵引区新骨中骨保护素（osteoprotegerin，OPG）的表达。

METHODS: Bone defects of 3.5 cm×1.5 cm in size were made in goat mandible. Osteoblastic cells/porites complexes were produced.

在羊下颌骨上造成3.5cm×1.5cm大小的骨缺损，缺损中植入钛网／珊瑚／成骨细胞，并设单纯珊瑚颗粒植入作为对照组。

Results There were significant differences between one-phase and two-phase treatment, we found the more mandible growth in two-phase treatment, and more dental compensation in one phase-treatment, such as retractive upper incisiors and procline of lower teeth.

结果：两组患者治疗后的颌面形态以及牙齿的角度和位置均有明显不同，即双期治疗组患者下颌骨有明显生长，单一使用固定正畸治疗患者，上前牙较直立，下切牙较唇倾。

During the treatment of skeletal Class ill malocclusion in mixed dentition, the reverse Twinblock could procline the upper incisor, accelerated the development of maxillary and mandibular ramus, and restrained the development of mandibular body. A randomly allocated prospective study was required to fully evaluate the bone efficacy of this appliance.

反向Twinblock矫治器可使上切牙唇倾、位置前移；在治疗期间能促进上颌骨的发育，抑制下颌体的发育，促进下颌升支的增高；反向Twinblock矫治器的对上下颌骨的长期作用有待进一步研究。

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。
