近年来，人们对牙齿咬合与身体姿势之间的关系越来越感兴趣，科学文献也越来越多。本纵向研究的目的是通过力平台和光电立体摄影分析来研究实验性咬合干扰对身体姿势的影响。制备了一种0- 2mm厚的玻璃复合材料的咬合干扰，以干扰牙尖间位置，而不会在下颌侧向或前突运动时产生干扰。对12名健康受试者进行了额角和矢状面运动学参数、动态步态测量和头颈部肌肉的表浅肌电图（SEMG）活动。在四种不同的外感受条件下，分别在应用咬合干扰前10天、应用前、应用后第二天、距离7天和14天进行测量。本研究结果表明，在不同的外感受条件下，咬合干扰不会随时间显著改变身体姿势的静态和动态参数。它仅对与下颌位置相关的额骨运动学参数有最小的影响，并引起咀嚼肌活动的短暂增加。在本研究中，在14天的随访期间，实验性咬合干扰对身体姿势没有显著影响。
In recent years, there has been increasing interest in the relationship between dental occlusion and body posture both among people and in scientific literature. The aim of the present longitudinal study is to investigate the effects of an experimental occlusal interference on body posture by means of a force platform and an optoelectronic stereophotogrammetric analysis. An occlusal interference of a 0- to 2-mm-thick glass composite was prepared to disturb the intercuspal position while not creating interference during lateral or protrusive mandibular excursions. Frontal and sagittal kinematic parameters, dynamic gait measurements and superficial electromyographic (SEMG) activity of head and neck muscles were performed on 12 healthy subjects. Measurements were taken 10 days before the application of the occlusal interference, and then immediately before the application, the day after it, and at a distance of 7 and 14 days under four different exteroceptive conditions. The outcomes of this study show that an occlusal interference does not modify significantly over time static and dynamic parameters of body posture under different exteroceptive conditions. It has a minimal influence only on the frontal kinematic parameters related to mandibular position, and it induces a transient increase of the activity of masticatory muscles. In this study, the experimental occlusal interference did not significantly influence the body posture during a 14-day follow-up period.
