Effect of neutral zone dentures on EMG of masticatory muscles and biting force 肌等压区排牙法全口义齿对咀嚼肌肌电和咬合力的影响
Conclusion The masticatory muscles of miniature pigs are similar with human being in the shape, start-stop point and orientation of muscle force. 结论小型猪咀嚼肌的形态、起止点、肌力方向都与人类有较大的相似性;
The contour of face and palate was satisfactory, the normal occluding relation was gained. The average masticatory force of operative side was 76.3% of the normal side. 面部外形双侧对称,腭部形态恢复良好,患侧咬牙合关系恢复正常,咀嚼牙合力达健侧的76.3%,临床效果满意。
Objective To study the expression of IL-1 β in the rat periodontal cells under normal and increased masticatory force, in order to explain the molecular mechanism of periodontal ligament ( PDL) remodeling. 目的检测咀嚼压力在正常及增强状态下,大鼠牙周膜成纤维细胞(PLF)IL-1β的动态表达,探讨IL-1β在牙周膜改建中的分子机理。
The modal analysis may be applied in the study of the teeth during being acted by masticatory force. 动力学模态分析可以有效地应用于牙在咬合力作用下力学变化的研究中。
Three-dimensional masticatory muscle force vectors determined by CT and MRI fusion image technology 利用CT和MRI融合技术确定咀嚼肌三维肌力向量
Effect of increased masticatory force on the expression of IL-1 β in the rat periodontal ligament 咀嚼压力增强对大鼠牙周膜IL-1β表达影响的研究
After five months, two magnets were adhered to the inside of the complete dentures. Retention, masticatory efficiency and maximal masticatory force were measured before and after the magnets were adhered and six months later. 对粘固磁体前、后及粘固磁体后6个月的义齿固位力、咀嚼效率和最大咬合力进行测试。
62 cases using bilateral free& end removable partial denture were selected Masticatory performance and biting force are tested, Occlusion sound was used to determine the state of occlusion. 本文采用吸光度法测定了62例肯氏Ⅰ类牙列缺损者戴用双侧游离端义齿前后的咀嚼效能。
Results Statistical analysis revealed that retention, masticatory efficiency and maximal masticatory force were all increased after the magnets were adhered ( P < 0.01) and six months later ( P < 0.01). 结果种植磁附着体全口义齿在粘固磁体后及粘固后6个月的固位力、咀嚼效率、最大咬合力均较放置磁体前明显提高,其差异具有统计学意义(P<0.01)。
Relationship between electromyographic activity of the masticatory muscles and variations of the bite force for edentulous subjects 无牙颌患者咀嚼肌肌电值与咬合力间的关系
A study on the masticatory efficiency and maximal bite force in the immediate complete denture wearers 即刻全口义齿修复者咀嚼效能、最大咬合力的研究
In order to measure and analyze three dimensional masticatory muscle force vectors in craniofacial region, the multiresolution method based on wavelet pyramid was used for the fusion of cranio jaw facial CT and MRI image, then these images were visualized. 采用基于小波金字塔分解的方法对颅颌面CTMRI医学图像进行融合,再经可视化技术处理,以测量和分析颅颌面部各咀嚼肌的三维肌力向量。
The study of masticatory performance of loosen teeth and PVDF-based instrument for dynamic chewing force measurement PVDF咀嚼力测试仪的研制及松动牙咀嚼生理功能的研究
Appropriate masticatory force is necessary to promote the growth of condylar cartilage. The relationship between changed masticatory force and development of condylar cartilage has drawn considerable attention. 正常的咀嚼力对于维持和促进髁突软骨的生长十分必要,咀嚼力改变与髁突软骨生长发育间的关系一直是研究的热点。
However, the research about the change of cell proliferation, cell apoptosis and the expression of Bcl-2 gene family in the condition of low masticatory force is scarce. 但是在发育阶段,关于髁突软骨细胞增殖和凋亡在咀嚼力降低时的变化,以及此过程中Bcl-2基因家族调节作用的研究极少。
