Joint Vibration Analysis (JVA) information.

BioJVA bJoint Vibration Analysis is based on simple principles of motion and friction. When smooth surfaces rub together, they cause little friction and little vibration. If these surfaces become rough, then friction and vibration are created when they articulate or rub together.

Jaw joints have surfaces which rub together in function. Smooth, well lubricated surfaces in a proper biomechanical relationship produce little friction and little vibration. Surface changes caused by displacement or damage of the joint disk, produce friction and vibration. Different disorders can produce different patterns or signatures. Computer assisted vibration analysis helps identify these patterns and helps to give a clearer understanding of what is happening in the joint. Dysfunctions of the joint develop slowly over a period of time, during which there are no discernible pains or symptoms. JVA is sufficiently sensitive to identify these changes at an early stage when treatment may be more effective and potential further deterioration can be avoided.

Joint Vibration Analysis is a system that records joint vibrations as they pass through the tissue. It provides a view of the pressure waves created by the jaw joint. The recording procedure is simple, involving placement of transducers that look like headphones over the jaw joints. Jaw opening and closing is synchronised with the computer and the patient is required to open and close repeatedly to record the reproducible vibrations. The information is then saved for analysis.
