(1)PURPOSEThe purpose of this study was to answer the question of whether certain morphological findings of malocclusions were associated with specific modes of chewing movements. The work was designed to assess the stability of chewing path and rhythm in normal and malocclusion subjects.(2)METHODThe chewing movements of malocclusions while chewing gum were recorded with a MKG and an NEC computer and were processed by an automatic masticatory movement analyzing software system. The following parameters in terms of the stability of chewing movements were considered : standard deviation (SD) values in lateral and vertical distances of opening and closing movements, coefficient of variation (CV) values in opening, closing, occluding and total cycle times.(3)RESULTThe data obtained from the malocclusion subjects as compared with those from a group of 67 normal healthy individuals showed statistically significant increments of SD values in lateral distance of the opening and in vertical distance as well as statistically significant increments of CV values in opening, closing, occluding and total cycle times. It is concluded that the stability of chewing movements in malocclusions is not very stable.

(1)目的本研究的目的是回答咬合错的某些形态学表现是否与特定的咀嚼运动模式有关。本研究旨在评估正常和错颌合受试者咀嚼路径和节奏的稳定性。(2)方法用MKG和NEC计算机记录错颌患者咀嚼口香糖时的咀嚼动作，并用自动咀嚼运动分析软件系统进行处理。咀嚼运动的稳定性考虑以下参数：开口和闭合运动的横向和垂直距离的标准差（SD）值，开口、闭合、咬合和总循环时间的变异系数（CV）值。(3)结果与67例正常健康人相比，错颌患者的数据在开口横向距离和垂直距离上的SD值增加有统计学意义，在开口、闭合、咬合和总循环次数上的CV值增加有统计学意义。结果表明，错咬合患者咀嚼运动的稳定性不是很稳定。
