为了建立一种客观的咀嚼功能评价方法，研制了咀嚼运动自动分析系统。应用该系统分析了正常受试者与颅下颌障碍患者咀嚼运动的差异。1. 开发了一种将咀嚼运动模拟信号转换为数字信号的系统，建立阈值，自动评估咀嚼运动的平均路径和开闭阶段的节奏。2. 在分析咀嚼卒中时，使用该系统与使用牙体卡尺在开启、关闭和闭塞时间上均无显著差异。3. 从嚼口香糖的第五笔开始的十笔在节奏和路径上都是最稳定的。4. CMD患者与正常人在节律和路径稳定性指标上存在显著差异。5. 节律和路径的稳定性在一个标准差以内为正常，节律4个指标中3个在正常范围内，路径3个指标中2个在正常范围内。6. 为客观评价咀嚼功能，制作了雷达图。
In order to establish an objectively evaluating method for masticatory function an automatic masticatory movement analyzing system was developed. Using this system the—differences in the masticatory movement between normal subjects and craniomandibular disorder (CMD) patients were analyzed. 1. A system was developed that can change the analog signals of masticatory movement to digital signals, establish threshold value, and automatically evaluate the average path of the opening and closing movement and the rhythm of the opening, closing and occluding phase. 2. No significant differences were found in the opening, closing, and occluding time when the system or the degimatic caliper was used in analyzing masticatory strokes. 3. The ten strokes beginning the fifth stroke of chewing gum were the most stable in both rhythm and path. 4. There were significant differences between CMD patients and normal subjects in the indicators for the stability of rhythm and path. 5. The stability of rhythm and path was considered normal if the indicators were within one standard deviation, and for the rhythm, if 3 out of 4 indicators, and for the path, if 2 out of 3 indicators were within normal range. 6. A radar chart was formulated for an objective evaluation of masticatory function.
