Influence of knowledge and behavior about oral health on health of periodontium 口腔健康知识及行为对维护牙周健康的影响
2.
The increment of periodontium stress was not proportional to the horizontal alveolar loss 牙周膜的应力随牙槽骨高度的降低呈非等比增加。
3.
Cytokines are expressed by cells within the periodontium in response to mechanical stress produced by orthodontic appliances 摘要在受到矫正装置所施与的力量后，牙周组织内的细胞会释放出细胞激素。
4.
Results : with the loss of the alveolar height , the maximum equivalent stress and the principle stress of the upper central incisor periodontium increased 结果：随着牙槽骨高度的降低，上中切牙牙周膜最大等效应力和主应力逐渐增大。
5.
Purpose : to study the stress variation and distribution of the periodontium and the tooth initial displacement when the lingual fixate forces were applied to the depressed periodontal height 摘要目的：研究牙周支持高度降低状态下施加舌向集中力时，牙周组织的应力变化、分布规律和牙的初始位移。
