Joint Vibration Analysis (JVA)

Friction is the result of a force as two bodies rub against each other. Human joints are generally connected by surfaces that are well lubricated and causes either minimal or no friction at all as they move against each other. If surfaces are rough and poorly lubricated, it leads to uneven surfaces that are constantly rubbing against each other causing wear and tear. 

A Joint Vibration Analysis is used to record and analyze vibrations caused by movement of joints, especially the Temporomandibular Joints. The TMJs are located on the left and right side of the jawbone below the ears. 

The Joint Vibration Analysis procedure is done by placing a device that looks similar to headphones on the left and right TMJs. The device is capable of capturing and recording vibrations as the patient opens and closes their mouth.

What causes the jaw joints to vibrate?

The upper and lower jawbone are connected to each other with a joint that has a small cartilage disc within. It is the presence of the cartilage that allows your mouth to slide open and close preventing the jaws from grinding against each other. In case they do, it is a sign of a damaged disc. The disc may get damaged due to several reasons such as trauma, orthodontic work, arthritis, clenching, and teeth grinding.

Treatment of TMJ vibration

Treating problems related to your TMJ (also known as a temporomandibular joint disorder) would depend on its cause and severity. In case the patient suffers from teeth grinding or clenching, the dentist would recommend a bite guard or a nightguard to wear during sleep thereby helping patients relieve themselves from stress experienced in the joints. A joint vibration analysis is the best instrument that allows dentists to make the correct diagnosis and treatment.
