We evaluated the usefulness of employing the occlusal force during swallowing as a parameter for determining the occlusal vertical dimension facilitating smooth, reproducible esophageal elevation. As a result, the occlusal force during swallowing in normal dentulous subjects significantly elevated with an increase in the vertical dimension. In maxillo-mandibular edentulous subjects, the occlusal force during swallowing became minimal with an appropriate vertical dimension, and significantly increased with an increase or decrease in the vertical dimension. In normal dentulous subjects, the saliva passage time during dry swallowing tended to decrease with an increase in the vertical dimension. These results suggest that the occlusal force during swallowing can be used as an objective parameter for the determination of the vertical dimension.

我们评估了在吞咽过程中使用咬合力作为确定咬合垂直尺寸的参数的有用性，以促进顺利，可重复的食管提升。结果，正常有牙受试者吞咽时的咬合力随垂直方向的增加而显著升高。在上下颌无牙颌受试者中，吞咽时的咬合力随着垂直尺寸的适当而变得最小，并且随着垂直尺寸的增加或减少而显著增加。在正常有牙的受试者中，干吞咽期间的唾液通过时间倾向于随着垂直尺寸的增加而减少。这些结果表明，在吞咽过程中的咬合力可以作为一个客观的参数来确定的垂直尺寸。
