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
Based on rolling characters of longitudinal profiled ( LP) plate, nip angle and biting condition are analyzed for LP plate rolling according to force condition. 基于纵向变截面轧制的特点,根据轧件受力分析了LP钢板轧制过程的咬入角和咬入条件。
The untreated rats 'mandibular molar area used as normal biting force model. The prepared tissue specimens were processed to study the change in histologic morphology with HE staining, and the expression of IL-1 β in PDLC and osteoblasts with immunohistochemistry ( IHC) technique. 用HE染色和免疫组化的方法,观察不同咬合力状态下牙周组织的形态学改变以及IL-1β在牙周膜成纤维细胞(PDLC)和牙槽骨成骨细胞中表达的动态变化。
Research on the Relation Between the Biting Force with Complete Denture and Compression of the Mandibular Denture Bearing Mucosa 全口义齿咬合力与下颌承托区粘膜变形度的相关性研究
CONCLUSION: It is concluded that mandible osteoporosis can result in a part of bone mine loss, which is related to age, sex, hormones, biting force, physical exercise and living habits, and so on. 结论:颌骨骨质疏松是全身骨矿丢失的一部分,受年龄、性别、激素、咬合力、体育锻炼以及生活习惯等因素的影响。
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。
Piezoelectrical PVDF-foil force sensor and its biting force measurement research 压电薄膜力传感器及其牙咬力的测量应用研究
Methods 10 edentulous patients with complete dentures were selected for this study. The maximum biting force and masticatory efficiency were recorded before and after application of the adhesive to all the new and old dentures. 方法测定10名患者使用粘附剂前后,新旧全口义齿的最大咬合力及咀嚼效能,以问卷形式调查患者的主观评价。
RESULTS: In the group of lost biting force, derangement of periodontal ligament and resorption of alveolar bone were observed in histologic study. The expression of IL-1 β in PDLC and osteoblasts enhanced apparently than in the group of normal biting force with IHC technique. 结果:咬合力丧失导致牙周膜结构紊乱、牙槽骨吸收,IL-1β在PDLC和成骨细胞中的表达,较正常咬合力时明显增强。
