title: Temporomandibular joint range of motion: a ratio of interincisal opening to excursive movement in a healthy population.
abstract: Range of motion is used in the examination and diagnosis of many joints. A simple method to measure and record temporomandibular joint range of motion is presented. Correlation of mandibular movement to excursive or lateral movements for a healthy population is described. The maximum incisal opening and lateral movements of 75 subjects, aged 20-50 years, were recorded. The average of maximum opening to lateral movements was found to be 4.4 to 1. A significant correlation or ratio of mandibular movement for use in diagnoses and treatment planning is discussed.
