[Experimental research on temporomandibular joint function in dysgnathic patients].

In an experimental study we examined the function of the TMJ of patients with a considerable aberration from ideal dynamic occlusion and with obvious symptoms of frontal dysgnathia. Using a measuring seat for the simultaneous recording of opening and closing movements without occlusal interference and the sounds produced by the TMJ, we could not find any significantly impaired TMJ function compared with an orthognathic control group of similar age.
