下颌骨

Results: The variety of the diameter of the abutment had close relationship with the stress.

建立了包含皮质骨和松质骨的正常人下颌骨三维有限元模型。

Methods The operations of angle-splitting ostectomy have been performed on 13 patients (11 female, 2 male) who had large, squarish, or broad face with eversion mandibular angle.

对下面部宽大，下颌骨体肥厚，下颌角外翻明显的&四方脸&者(13例，其中男性2例，女性11例)进行了下颌骨体部的劈裂截骨术和部分咬肌去除术。

In addition to zygomatic arch ligament observation, mandibular ligament, ligament platysma ears, before the ligament platysma skin, SMAS-zygomatic cheek cruciate ligament and the mandible, in the mandibular angle, lateral numbness of the mouth, etc.

除观察致颧弓韧带、下颌骨韧带、颈阔肌耳韧带、颈阔肌皮肤前韧带、SMAS-颧颊韧带和下颌骨韧带外，在下颌角、口角外侧、外眦外侧等处亦有皮肤支持带存在结论面部皮肤支持带粗、细不等，长、短不一，除皱术中需剪断和重建某些韧带，以达到最大程度的松解和提紧效果。

Methods: Forty adult Wistar rats were used for these operations of transplantation of frozen autogenous tooth-mandible compound and fresh ATMC. Then the healing process after transplantation of frozen ATMC and fresh ATMC was compared by clinical, radiographical, histological and microangiographical observation.

选用健康成年Wistar大白鼠40只，任取2只用于观察正常颌骨的组织学图像，其余的大鼠随机分为新鲜移植组和冷冻组，行牙-下颌骨复合组织块移植到胫骨区的手术，分别于术后1、2、3、4、6、8、12、16、20周时处死动物，采用大体观察、X线片、组织学及微血管造影等观察手段对牙-下颌骨复合组织块移植后的愈合过程进行比较。

The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors.FR-Ⅲ also promotes the growth of maxilla and reaches the normal relationship of the anterior overjet and overbite.

结果：FR-Ⅲ能矫正上下颌基骨异常的矢状关系，主要变化是下颌骨向下、向后旋转，改变下颌骨生长的方向，同时使下颌切牙舌倾、上前牙唇倾，上颌骨向前生长。

Results The lower perforated edge of the inferior maxilla mangled by the thread for the hole was too low in 1 case. Incisions on the neck were fat liquoring in 6 cases. 3 cases had repeated inflammation, which was probably because the incision was irritated by the suture. 2 cases had bleeding from the incision.

结果 1例患者术中下颌骨下缘打孔过于偏下，穿线打结后丝线将下颌骨打孔处下缘撕裂；6例患者术后颈部切口出现脂肪液化；3例患者颏部切口反复红肿，考虑缝线局部刺激；2例患者术后出现颈部切口出血。

The bilateral masseter muscles of rabbits were detached from inferior maxilla and then reposited after mandible reduction TGF-β1 was regularly injected into one lateral of masseter muscles and the other lateral was taken as control.

将实验用兔的双侧咬肌从下颌骨附着处剥离，下颌骨截骨后将咬肌复位，一侧定期注射转化生长因子β1，另一侧作为对照。

Objective To observe the relationship between the change of stress environment of mandibles and their bone mass in normal and ovariectomized rats.

目的 观察双侧卵巢切除(ovariectomy ，OVX)大鼠下颌骨应力环境改变与下颌骨骨量的关系。

Part 1: The animals were randomly divided into 2 groups: Group A have no latency period and group B have a 7 days latency period.

观察有无延迟期对下颌骨DO成骨情况的影响，探讨在下颌骨DO过程中延迟期是否必要。2。

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。
