In normal chewing the forces exerted on the occlusal surface seldom exceeded 10 to 15 pounds, as recorded by an eight-channel force transmitter in a removable fixed partial denture. Ninety-five percent of forces were less than 3.5 pounds for subject A, 2.0 pounds for subject B, and 10.0 pounds for subject C. The chewing frequency and the places of maximal force on the occlusal surface were relatively constant. The electromyographic chewing patterns could be considered normal in all circumstances. There was a remarkable statistically significant day-to-day variation in force values. The forces also changed for different kinds of food. The differences between maximum and minimum force values were highest in voluntary, nonfunctional movements.
在正常咀嚼过程中，可摘固定局部义齿中的八通道力传感器记录到，施加在咬合面上的力很少超过10至15磅。受试者A的95%的力小于3.5磅，受试者B为2.0磅，受试者C为10.0磅。咀嚼频率和咬合面上最大力的位置相对恒定。在所有情况下，肌电图咀嚼模式均可视为正常。力值存在显著的统计学上的每日变化。对于不同种类的食物，力也会发生变化。在随意的、无功能的运动中，最大力值与最小力值之间的差异最大。
