[The general even mandibular movements as couple movements in neuromuscular guided mechanism].

Abstract

The manifold mandibular movements of oral aperture can be modelled by movements of couples in neuromuscular gear systems. These systems consist of the dimeric link chain of the neuromuscular hinge axis (rocking arm) and a neuromuscularly enforced cyclic trajectory of a well-defined point of the mandible. The neuromuscular hinge axis is the common constant of all gear systems whereas the position of the cyclic trajectory at the fixed plane (maxilla) is closely related to the specific path of the entire rigid body mandible. The presented theory is inferred by measurements of the mandible's movement that take all six degrees of freedom into account.
