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.
