- Objective To investigate the process of masseter muscle reattachment to the cortical and cancellous bone of the mandible. 摘要目的研究山羊咬肌与下颌骨皮质骨面和松质骨面再附著的生物力学特性变化。
- The area of hiatus and the muscular thickness of the crura increased with age.The hiatus area to crura muscle thickness ratio decreased with age (P<0.05). 食管裂孔面积和肌厚随婴儿年龄而逐渐增加,而裂孔肌相对厚度与胎儿组比较均减少(P<0.;05)。
- For experiment group, the electromyogram and membrane potential of jaw movement and masseter muscle after loss of tooth were detected. 方法:通过对24只大耳白兔随机分组,对实验组动物进行牙齿丧失后的下领运动,咀嚼肌肌电图、膜电位的检测,将变化的生理功能信号进行比较分析。
- Muscle sections of the masseter muscle were weighted and the anthropometric measurements were made directly on rat dry skull . 而后将75天年龄大的大白鼠杀死,取下咬肌测量重量,及量测乾燥头颅骨。
- Mandibular angle ramus outermost part of bony plates called bone plate, which is equivalent to masseter muscle attachment surface. 下颌角升支部分最外层骨板叫骨外板,相当于咬肌附着面。
- The pain response was assessed by visual analogue scale (VAS) in order to investigate the influence of orthodontic pain on masseter muscle activity. 并配合视觉类比尺度(VAS)记录受测者疼痛程度,以研究矫正疼痛对咬肌活性之影响。
- MPS can significantly reduce the hyperactivity of elevators and enhance the symmetry of masseter muscle activity,and thus the signs and symptoms of CMD continuously subsided. 肌位?板可明显减小磨牙症伴CMD症状者升颌肌异常过度活动 ,且提高嚼肌肌电活动的对称性 ,从而使CMD症状持续性缓解
- CONCLUSION: After the angle-grinding ostectomy, the hypertrophy masseter muscle can get atrophy itself during 24 weeks.But there was no change in masseter muscle. 结论:下颌角磨削去骨后24周内肥大的咬肌会出现自行萎缩,不需处理,24周后咬肌不再有变化。
- It was concluded that orthodontic pain produced by orthodontic treatment was the reason that reduced the masseter muscle activity during the pain period. 综合以上所述,齿颚矫正治疗会产生矫正疼痛,而此种矫正疼痛是造成疼痛过程咬肌活性降低的原因。
