本研究旨在探讨食物厚度与咬合力的关系。我们设计了一种新的传感器，它可以检测一侧切牙和磨牙之间的压力分布，以及食物样品与牙齿之间的接触面积。利用多点薄片传感器直接对压力和接触面积进行真实的实时测量。将硅橡胶块作为样本食物，由10名健康女性用切牙和磨牙咀嚼。对于较厚的样本，切牙之间的峰值力、接触面积、持续时间和脉冲更大。对于不同厚度，峰值时的有效压力（定义为力与接触面积的比值）相似。相比之下，对于2 mm厚的样本，峰值力和力相关参数在磨牙咀嚼中最大。磨牙的咀嚼力、接触面积和持续时间均大于切牙。我们验证了样本的厚度会影响人类的咀嚼力，并且这种影响在切牙和磨牙之间存在差异。
The aim of this study was to investigate the relationship between thickness of sample food and bite force. We designed a new sensor that can detect the pressure distribution between the incisor and molar teeth on one side, and the contact area between the food samples and the teeth. The force and contact area were directly measured in real time using the multiple-point sheet sensor, which is a very thin and flexible pressure-sensing device. Silicone rubber blocks were used as a sample food and were chewed with incisors and molars by 10 healthy women. The peak force, contact area, duration and impulse were greater between the incisors for a thicker specimen. The active pressure, defined as the ratio of the force to contact area, at peak was similar for different thicknesses. In contrast, with a 2 mm thick sample, the peak force and force related parameters were greatest in molar chewing. The force, contact area and duration were greater for molar chewing cycles than incisor ones. We verified that the thickness of samples influenced the chewing force of humans and the effects differed between incisors and molars.
