Jaw joint diagnostics
(instrumental functional diagnostics)

The muscles of the masticatory system (teeth and jaw joints) are connected to the neck and backbone muscles and constitute a functional unit.


If the maxilla and mandible do not meet each other in an ideal position, minimal deviations can trigger various symptoms, such as head, neck, shoulder, joint or back pain, ringing in the ears, sleep disorders and teeth grinding. In professional dentistry, we talk about a dysfunction of the masticatory system or “craniomandibular dysfunction”.


Instrumental jaw joint diagnostics using the DIR system is designed to detect faults in the jaw and teeth. The diagnostic examination is painless and quick. It involves placing a small plastic template with a measuring sensor on the teeth. The patient then closes his or her mouth and – guided by the dentist – performs a series of jaw movements. These appear on a screen and are evaluated by the dentist.


With the aid of this evaluation, it is possible to set an optimised bite. This in turn serves as a basis for the next therapy. A stable and stress-secure bite protects all neighbouring structures, such as cartilage, bones, ligaments and muscles, and ensures lasting relief from symptoms.
