The energy used to break down food was calculated in Angle Class I and rigid interdigitation, as well as in various malocclusions using a computer simulation. As a result, the energy applied to the food was the highest in Angle's Class I molar relationship and rigid interdigitation, with a simple pattern of masticatory movement. This relationship also tended to produce maximum efficiency in the posterior teeth, including the premolars. Furthermore, energy decreased with the degree of malocclusion. Thus, we were able to provide an alternative definition of Angle's Class I molar relationship and rigid interdigitation. In addition, the extent of malocclusion could be evaluated quantitatively.
利用计算机模拟计算了安氏I类和尖窝相对关系以及各种错牙合情况下分解食物所消耗的能量。结果表明，在安氏I类磨牙关系和尖窝相对关系中，咀嚼运动模式简单，施加于食物的能量最高。这种关系在后牙（包括前磨牙）中也往往能产生最大效率。此外，能量随着错牙合程度的增加而降低。因此，我们能够为安氏I类磨牙关系和尖窝相对关系提供另一种定义。此外，错牙合的程度可以进行定量评估。
