牙骨

Your dentist will then put abetment on the implant, sometimes this is done during the initial implant operation depending on the positions of your bones and teeth.

有时医生会根据您牙骨及牙位情况，选择在植入牙体的同时连基台一起装上。甚至同时戴上临时亚冠，是您即刻拥有灿烂笑容。

Then the alveolar bone of model 1 was lowered to respectively construct Model 2(Bone loss was one fourth of the root), Model 3(Bone loss was one third of the root), Model 4(Bone loss was the half of the root), Model 5 (Bone loss was the two third of the root) and Model 6 (Bone loss was the three fourth of the root).

在模型1基础上，将牙槽骨骨高度分别删除1层、2层、3层、4层、5层(使处理后的牙槽骨骨高度与牙根长度之比由1：1变为3：4、2：3、1：2、1：3、1：4)，产生模型2、模型3、模型4、模型5、模型6，代表五种不同程度的牙槽骨骨吸收模型。

Results 4 factors (mandible rotation factor, facial height factor, dental and skeletal saggital factor and maxillar rotation factor) were extracted from 156 items including age, gender and craniofacial characteristics by data reduction and factor analysis procedure.

结果对年龄、性别、颅面特征等156项指标经聚类和主成分分析精简为30个变量，再通过因子分析提取出4个因子（下颌旋转因子、面高因子、牙骨矢状因子和上颌旋转因子）。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。

Careful treatment can decrease the complication rate. 3. Three-dimensional finite element model analysis showed that zygomaticoalveolar crest is the major site sustaining stress, which indicated that the fixation of zygomaticoalveolar crest should be strengthened, if there is some space between zygomaticoalveolar crest and fibula bone, free bone graft can fill the space to rebuild the bony zygomatic process support.

游离腓骨复合组织瓣上颌骨重建的三维有限元分析表明，颧牙槽嵴部位是腓骨瓣上颌骨重建后咀嚼压力的主要受力部位，提示腓骨瓣上颌骨重建时要加强颧牙槽嵴的固定；当上颌骨切除后腓骨与颧牙槽嵴存在间隙时，应尽量采取游离骨块移植，充填间隙，重建骨性颧突支柱。

After cleaning, dehydrate, dessication and carbon plating, the elements concentration was detected andanalyzed by x-ray energy dispersive system. Other samples were drawn and fixed in formalin solution. With decalcification and dehydration, samples were embedded in paraffin and cut into 5-um sections.

一部分标本用戊二醛固定，在液氮致冷条件下沿牙齿近远中方向水平劈断牙骨块，暴露观察面，经过清洗、脱水、干燥、真空下镀碳膜并做X线能谱分析及元素定量测定；剩余部分样品经过福尔马林固定、脱钙、脱水、包埋及常规HE染色，于光镜下进行组织学观察。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
