The purpose of this study was to establish an index for evaluating occlusal conditions using energy levels. For this purpose, first, the movement of mastication under five occlusal conditions in which the positional relationship varied mesiodistally was simulated and the energy applied to the food being masticated was calculated, based on theoretical values of computing mechanics using finite element static analysis. As a model experiment, the energy generated under each occlusal condition was then measured using the electrical output from an occlusion pressure sensor composed of pressure-sensitive rubber. By comparing the theoretical values of computing mechanics and the measured values, the changes in the energy level under occlusal conditions were consistent with the trends, and the maximum value of the energy was obtained under the occlusal condition of Angle Class I and consisting of rigid interdigitation. In conclusion, our results demonstrated that occlusal conditions can be evaluated using the energy level as an index.
本研究的目的是建立一个使用能量水平来评估咬合状况的指标。为此，首先，基于有限元静态分析的计算力学理论值，模拟了五种近远中位置关系不同的咬合状况下的咀嚼运动，并计算了施加于被咀嚼食物的能量。作为模型实验，然后使用由压敏橡胶制成的咬合压力传感器的电输出来测量每种咬合状况下产生的能量。通过比较计算力学的理论值和测量值，咬合状况下能量水平的变化与趋势一致，并且在安氏I类且为紧密牙尖交错的咬合状况下获得了能量的最大值。总之，我们的结果表明，咬合状况可以使用能量水平作为指标来进行评估。
