Correlation between interdental occlusal plane and plantar arches. An EMG study.

The Authors carried out an experimental study on a homogeneous group of young people to provide evidence of functional correlation among masticatory muscles and, indirectly, between changes to the interdental occlusal plane and modifications of the plantar arches due to talipes valgus and flat foot. In the two analysed conditions, the masticatory muscles undergo different functional alterations. This is due to the fact that the mechanoreceptors in the tendons of the muscles governing the plantar arch configuration are stimulated in different ways during the activation of long osteoarthromuscular chains. Dental specialists will have to take these correlation into account when diagnosing TMJ disorders.
