为了解习惯性咀嚼侧与非习惯性咀嚼侧咀嚼运动的差异，采用咀嚼运动自动分析系统，对20名正常人咀嚼口香糖时的第5 ~ 14次咀嚼动作进行分析，计算并比较两侧咀嚼运动的张开距离、平均路径、节律、咀嚼路径和节律的稳定性.平均路径可以分为两类。在几乎所有的被试中，习惯性咀嚼侧和非习惯性咀嚼侧都表现出相似的模式。习惯性咀嚼侧与非习惯性咀嚼侧的开口距离无显著性差异.两侧咀嚼路径的稳定性差异有统计学意义，非习惯性咀嚼侧稳定性较差.两侧咀嚼节律无显著性差异。虽然个体间存在差异. 20例中14例咀嚼节律的稳定性存在差异，非习惯性咀嚼侧稳定性较差.人们认识到，非习惯性咀嚼侧在路径和节奏方面都不如习惯性咀嚼侧稳定。因此，双方在功能上有所不同。
In order to find the difference between the habitual chewing side and the nonhabitual chewing side during mastication, the 5th stroke to the 14th stroke of 20 normal subjects masticating chewing gum were analyzed using the automatic masticatory movement analyzing system, and the opening distance, average path, rhythm, and the stability of chewing path and rhythm were calculated and compared between the two sides.1. The average path can be classified into 2 classes. Both the habitual and the nonhabitual chewing sides showed similar pattern in almost all the subjects.2. No significant differences were found in the opening distance between the habitual and non-habitual chewing sides.3. There were significant differences in the stability of chewing path between the two sides with the non-habitual chewing side being less stable.4. No significant differences were found in the chewing rhythm between the two sides. Though differences among individual subjects were found.5. There were differences in the stability of chewing rhythm between the two sides in 14 out of 20 cases with the non-habitual chewing side being less stable.6. It was recognized that the non-habitual chewing side is less stable than the habitual chewing side in both path and rhythm. Thus functionally the two sides differ.
