This study recorded the influence of 30 minutes of intense chewing on the masticatory function in 17 healthy subjects. Functional recordings of mandibular movements and velocity, measurements of masticatory efficiency, maximal occlusal force, and occlusal force endurance time were performed before and after functional stimulation and finally in a 2- to 5-day follow-up registration. After intense chewing, a substantially decreased masticatory cycle and occlusal level phase duration were recorded. No major mandibular displacements or changes in velocity were recorded. Masticatory efficiency and maximal occlusal force in the incisal region diminished after 30 minutes of intense chewing. Occlusal force endurance time was also lowered after intense chewing. The measurements were close to their original values at the follow-up. Intense chewing had various short-term effects on masticatory function, including a significant reduction of masticatory efficiency, maximal occlusal force, occlusal force endurance, and masticatory cycle duration.
本研究记录了17名健康受试者在进行30分钟剧烈咀嚼后对咀嚼功能的影响。在功能刺激前后以及最后在2至5天的随访记录中，对下颌运动和速度进行功能记录，测量咀嚼效率、最大咬合力和咬合力耐力时间。剧烈咀嚼后，记录到咀嚼周期和咬合水平阶段持续时间显著缩短。未记录到明显的下颌移位或速度变化。在进行30分钟剧烈咀嚼后，切牙区的咀嚼效率和最大咬合力降低。剧烈咀嚼后咬合力耐力时间也缩短。随访时测量值接近其初始值。剧烈咀嚼对咀嚼功能有多种短期影响，包括咀嚼效率、最大咬合力、咬合力耐力和咀嚼周期持续时间显著降低。
