The purpose of this article is to review the literature concerning the ideal chewing pattern for best chewing performance. We conclude that at this time there is not one ideal chewing pattern which can be used clinically or in research to assess the health of the mastication apparatus nor to predict chewing performance. It is clear that human masticatory behaviour is one of the most complex human behaviours. Chewing is under the control of the central pattern generator located in the brain stem but is influenced by dental and temporomandibular joint morphology. The most important portion of the chewing cycle is the area entering and leaving the intercuspal position where gliding contacts occur. Maximal chewing capability will likely occur when the chewing pattern follows the dental anatomy unique to the individual. The chewing cycle appears to increase the lateral component of its movement when increased chewing efficiency is required. These situations include increased hardness or the size of bolus, the position of the bolus and the results of the proceeding chewing stroke. The chewing pattern for any one cycle is influenced by a number of factors, thus it is not surprising that the question of the ideal chewing pattern remains unresolved.
本文的目的是回顾关于最佳咀嚼性能的理想咀嚼模式的文献。我们得出的结论是，目前不存在一种可在临床或研究中用于评估咀嚼器官健康状况或预测咀嚼性能的理想咀嚼模式。显然，人类的咀嚼行为是最复杂的人类行为之一。咀嚼受位于脑干的中枢模式发生器控制，但受牙齿和颞下颌关节形态的影响。咀嚼周期中最重要的部分是进入和离开牙尖交错位（发生滑动接触）的区域。当咀嚼模式遵循个体独特的牙齿解剖结构时，最大咀嚼能力可能会出现。当需要提高咀嚼效率时，咀嚼周期似乎会增加其运动的侧向分量。这些情况包括食物团块硬度增加或尺寸增大、食物团块的位置以及先前咀嚼冲程的结果。任何一个周期的咀嚼模式都受多种因素影响，因此理想咀嚼模式的问题仍未解决也就不足为奇了。
