mandibular position affects the cervical spine alignment which I believe alters nerve flow. This hypothesis is based on the change in leg length seen once the appliance is in the mouth
any dental appliance that is changing the mandibular position should ideally be checked to ensure it is not disrupting the balance and harmony of the nervous system
Another fabulous example of this is shown below where Ron Hruska (PRI) demonstrates how incorrect jaw positioning can affect gait.
