A Quantitative Analysis of the Decrease in Width of the Mandibular Arch during Forced Movements of the Mandible

Abstract

A procedure is described for quantitatively analyzing the decrease in mandibular width occurring from rest to a forced wide-open and forced protruded position of the mandible. An analysis of the 20 patients studied indicated that the nature of the response in all cases was similar; a decrease in mandibular width in the molar region from rest to wide-open and in forced protrusion was demonstrated.
