The texture which shows physical properties, such as hardness of a food, was associated with the swallowing easy, and the difficulty of swallowing was shown as a hardness stress and coherence went up. However, in a small alteration of the texture, the muscles activity during swallowing was not affected. When the food texture became remarkably large during free swallowing of the edentulous, the muscles activity became large and strong tongue pressure produced it still longer. Moreover, when a texture was large, the muscles activity with artificial tooth arch tended to become quick greatly.

表示物理性质的质构，如食物的硬度，与吞咽的容易性有关，吞咽的困难表现为硬度应力和凝聚性上升。然而，在质地的一个小的变化，吞咽过程中的肌肉活动不受影响。当无牙颌患者自由吞咽时，食物质地变得非常大时，肌肉活动变得很大，强大的舌压使其产生更长的时间。此外，当纹理较大时，人工牙弓的肌肉活动倾向于变得更快。
