Relationship between the temporomandibular joint and pantographic tracings of mandibular movements. 1980

F Mongini

Lateral polytomography of the TMJ and pantographic tracings of mandibular movement were performed in 30 patients with TMJ pain-dysfunction syndrome. The condyles were classified as rounded or flattened. The articular eminences were classified as convex or flattened. Two types of immediate side shift, progressive side shift and vertical protrusive tracing, were observed. Type A was curved, Type B was straight. A significant relationship was found between the shape of the TMJ and the tracing pattern. Type A immediate side shift (when present), progressive side shift, and vertical protrusive tracings were more typical of patients with rounded condyles and convex articular eminences. Type B was typical of patients with flattened condyles and, to a lesser extent, flattened articular eminences. Superior displacement of the rotating condyle was found only in patients with flattened condyles.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D003766	Dental Occlusion	The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication.
