为了解释错牙合患者在颌运动时颈部的疼痛和功能障碍，需要了解颌运动和颈部运动之间的生理关系。然而，复杂的反射效应使得研究头颈部组件之间的生物力学关系变得困难。出于这个原因，我们已经创建了一个模型，用于正常口颌系统的机械系统动态分析，以评估颈部运动和肌肉活动在下颌运动的生物力学。我们还对模型进行了统计学验证，并通过颈部肌肉活动的量和条件对人类受试者进行了定量验证。在下颌张开-闭合阶段，模型的运动与具有相同运动的受试者高度相关。然而，在尖牙间期实现了低一致性。这些结果表明，建立了一个有效的系统，可以用来评估生物力学的关系，颌和颈部运动。此外，颈部肌肉活动的模型验证表明，颌部的机械作用可以成为改变颈部肌肉的主要因素，颈部肌肉协调抵抗颌部运动时头部平衡的变化，以维持头部姿势。
To explain the pain and dysfunction of neck during jaw movement associated with malocclusion, the physiologic relationships between jaw and cervical movement should be understood. However the complicated reflex effects made it difficult to investigate the biomechanical relationship between the head-neck components. For this reason we have created a model for mechanical system dynamic analysis of the normal stomatognathic system to assess the biomechanics of the cervical movement and muscle activity during jaw movement. We have also statistically validated the model and quantitatively verified the model to the human subject by the amounts and conditions of cervical muscle activity. During jaw opening-closing phases the movement of the model was highly correlated to the subject with an identical movement. However low consistency was achieved during intercuspid phase. These findings indicate the establishment of a valid system, which can be used to evaluate the biomechanical relationships between jaw and cervical movement. Moreover the model verification of cervical muscle activity indicate the mechanical action of jaw can be the primary factor to modify cervical muscles, and cervical muscles coordinate to resist changes in head balance during jaw movement to maintains head posture.
