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.
