A two-stage posterior subapical osteotomy was used to reestablish the intermaxillary space. Following orthodontic treatment and implant placement, the patient regained occlusal harmony and normal masticatory function.

经分析拟定其治疗计划为：上颚后牙区以门诊手术进行二阶段的后上颚根尖截骨术，增加颚问垂直距离，并以局部矫正装置改正咬合平面，最后利用人工植牙方式来制作补缀物，来恢复病患的咀嚼功能。

Stress distribution of the natural periodontal membrane, bionic periodontal membrane and the bone interface of the three models are calculated out by SuperSAP93, when the same load exerted to the three models.

First, the majority of change in orthodontics appears to be dento-alveolar in nature.

首先，大多数的变化正畸似乎牙牙槽骨的性质。

Experiment two Influence of fiber framework design on stress distribution in posterior GFRC-RBFPD By comparing the difference of stress distribution among models with different fiber frameworks, the reinforcement mechanism and effect of different framework designs were discussed.

建立的〓和〓桥基牙、GFRC-RBFPD及其相关牙周组织和牙槽骨的三维几何模型，以及三维有限元模型具有很好的转换性，可以针对不同力学问题进行分析研究。

Methods In four kinds of prosthodontia design models, stress distributions in the remaining sections of the alveolar bone of the mandibular first molar with hemisection models were evaluated.

运用光弹应力冻结切片法，分析⑤⑥⑦、⑤⑥、⑥⑦、⑥固定桥修复模型的第一磨牙半切术后余留根牙槽骨应力分布状况。

He effect of antibiotics in inducing the formation of apices is to prevent infection of root canal, rather than direct induction. And TGF-β1 might act as an inductive factor in the cell differentiation of the above-mentioned cells.

GF-β1参与了尖周组织的修复过程，可能诱导了成牙本质样细胞、成牙骨质样细胞和骨样细胞的分化，在牙根继续形成中起着重要作用。

AIM:To observe the expression of Smad1,4,5 in h uman dental pulp tissue of normal, carious and inflammatory couditions, and explore the effect of Smad1,4,5 on dental pulp repair after tissue injury.

目的：观察骨形态发生蛋白下游信号转导分子Smad1，4，5在正常、龋坏和炎症人牙髓组织中的表达及表达差异，探讨Smad1， 4，5在牙髓损伤修复过程中的作用。

Animals were divided into control group and 5 experimental groups. Each experimental group had 2 canines and the central of masseters and geniohyoid were dissected out in 5th, 10th day in distraction and 2nd, 4th, 8th week after distraction.

牵张器采用口内下颌骨牵张器，截骨部位在第三乳前磨牙与第一恒磨牙间且垂直于下颌骨下缘，牵张方向为前后向。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
