What Is Joint Vibration Analysis?
Joint Vibration Analysis (JVA) is a cutting-edge computerized technology that measures and analyzes vibrations in your temporomandibular joints (TMJ) within the jaw. This test is crucial for evaluating symptoms of temporomandibular disorders (TMD) and monitoring the condition of individuals affected by TMD. The JVA procedure is quick and simple, using a headset equipped with accelerometers, an amplifier connected to a computer, and specialized JVA software for precise assessment.
What is the purpose of
conducting a Joint Vibration Analysis?
When your jaw joints (TMJs) are functioning properly, they move smoothly without friction or noise during activities like eating, drinking, or talking. However, changes in the surface of the jaw joint can lead to friction or vibrations. This often happens in individuals who have experienced significant impacts to their jaws, suffered previous injuries, or have abnormal jaw function. Such changes can result in popping sounds or vibrations in the jaw, which can be identified through joint vibration analysis (JVA).
Sometimes, these vibrations may not be audible to the human ear, which is why JVA is employed to amplify the sound. If vibrations are detected in your jaw, it could indicate an underlying condition, such as temporomandibular disorder (TMD).
During a JVA, accelerometers—electronic sensors that measure and record the motion and friction of the jaw joint surface—are utilized. These sensors capture the type, size, and pattern of the vibrations, providing valuable data for diagnosing joint disorders.
In summary, joint vibration analysis is a vital diagnostic tool for detecting even subtle vibrations in the jaw joint. It offers critical insights into the joint's condition and aids in the diagnosis of joint-related disorders.
How does
the process of JVA work?
First, the dentist will place a specialized headset on your head. This headset resembles headphones, but it features earpieces equipped with accelerometers positioned around the TMJ (jaw) area.
These accelerometers are connected to an amplifier worn around your neck, which enhances the detection of even the faintest vibrations.
Once the setup is complete, you will be asked to open and close your jaw. The dentist will use the amplifier to detect any vibrations or sounds produced during this process. The detected vibrations are then displayed and recorded by the JVA computer software for detailed analysis.
