BioJVA™ Joint Vibration Analysis is based on simple principles of motion and friction: When smooth surfaces rub together, little friction is created…and little vibration. If these surfaces become rough, then friction and vibration are created when these surfaces articulate.

JVA provides a fast, non-invasive, and repeatable measurement of TMJ function to aid in your diagnosis of TMJ function. Understanding TMJ function is vital anytime you are changing the vertical, lateral, or A/P position of the mandible. Common treatments that change mandibular such as TMD treatment, Orthodontics, Prosthodontics, Reconstruction and Sleep Dentistry can all from JVA testing.

Human joints have surfaces which rub together in function. Smooth, well lubricated surfaces in a proper biomechanical relationship produce little friction and little vibration. But surface changes, such as those caused by degeneration, tears, or displacements of the disk, generally produce friction and vibration.

Different disorders can produce different vibration patterns or “signatures”. PC-assisted vibration analysis helps identify these patterns and helps you distinguish among various TM disorders.

A JVA recording only takes 10 seconds of patient time, and less than 3 minutes of staff time. In less than 10 minutes, your staff can be trained to take accurate, repeatable data.Interpretation is done by the clinician and takes only a few minutes. For those clinicians looking for an in-depth education on JVA interpretation, our 3-day TOTAL BioPAK seminar is included with the purchase of a JVA system.
