Authors investigated the effects of different jaws relations on body posture in a sample of 95 subjects. All subjects underwent a posturometric and stabilometric analysis using a computerized footboard. Tests were performed in three mandibular positions: centric occlusion, rest position and myocentric position, respectively determined by teeth engagement, joints position, and muscles contraction. All subjects showed variations of body posture in the different mandibular positions. Statistical analysis (analysis of variance for repeated measures) confirmed that postural variations in different jaws relations were significant: in particular, the SKN multiple comparison test showed that myocentric position improved postural balance on frontal plane with respect to the other jaw positions considered.
作者在95名受试者样本中研究了不同颌关系对身体姿势的影响。所有受试者均使用电脑化踏板进行了姿势测量和稳定测量分析。测试在三种下颌位置进行：正中咬合位、休息位和肌位，分别通过牙齿咬合、关节位置和肌肉收缩来确定。所有受试者在不同下颌位置均表现出身体姿势的变化。统计分析（重复测量方差分析）证实，不同颌关系中的姿势变化具有显著性：特别是，SKN多重比较检验表明，与其他所考虑的颌位相比，肌位改善了额平面上的姿势平衡。
