[Positions of the central relation and central occlusion as recorded by a functiograph in patients with a stomatognathic system dysfunction].

Positions of the central relation and central occlusion were intraorally graphically recorded in 100 patients with a stomatognathic system dysfunction and in 0 control subjects. Results of the study showed asymmetry of these two positions to play a major role in the etiology of dysfunction. Occlusal program had an almost two-fold impact on the graphic tracing of the central occlusion position, as compared to the influence exerted by the articulation and muscle on the central relation tracing. Instrumental functional analysis and the instrument used alike, are simple to use and allow an objective assessment of the state to be made.
