As a result of the increasing frequency and diversity of symptoms, as well as an increase in the intensity of the disease process, simple clinical studies tend to be insufficient. The use of modern, often complex diagnostic techniques is essential, especially in patients with severe symptoms of stomatognathic system dysfunction, often combined with morphological changes. The factors causing dysfunction of the stomatognathic system include the following: bite disorders, mental stress, habits, acute and chronic injuries, functional muscle disorders, and iatrogenic factors. Bite disorders are a cause which raises the most controversy, especially those in the form of a malocclusion. We present a case of a young woman diagnosed with severe dysfunction of the temporomandibular joints, caused by traumatic unaligned bite, which is a consequence of untreated dental malocclusion. With the help of electronic devices, Zebris JMA and Tekscan, the kinematics of the mandible and the distribution of compressive forces on the dental arches from diagnosis to completion of treatment were monitored. Images produced using the instrumental techniques show the effectiveness of orthodontic procedures as a method for the treatment and prevention of temporomandibular joint dysfunction.

Key words: malocclusion, TMJ dysfunction, instrumental techniques.
