What Is Joint Vibration Analysis?
Joint Vibration Analysis (JVA) is an advanced computerized technology designed to measure and analyze vibrations in your Temporomandibular Joints (TMJ) within the jaw. This test is essential for evaluating symptoms of Temporomandibular Disorders (TMD) and tracking the condition of individuals suffering from TMD. The JVA procedure is quick and straightforward, utilizing a headset with accelerometers, an amplifier linked to a computer, and specialized JVA software for accurate assessment.
What is the purpose of
conducting a Joint Vibration Analysis?
When your jaw joints (TMJs) are functioning properly, they should move smoothly without any friction or sounds during activities like eating, drinking, or talking. However, if there are changes in the surface of the jaw joint, it can lead to friction or vibrations. This often occurs in people who have experienced forceful impacts to their jaws, previous injuries, or when the jaw isn't functioning normally. These changes can cause popping sounds or vibrations in the jaw, which can be detected through a joint vibration analysis (JVA).
Sometimes, these vibrations might not be audible to the human ear, which is why JVA is used to amplify the sound. If your jaw shows signs of vibrations, it might indicate an underlying condition such as temporomandibular disorder (TMD).
During a JVA, accelerometers—electric sensors that measure and record the motion and friction of the jaw joint's surface—are used. These sensors help capture the type, size, and pattern of the vibrations, providing valuable information for diagnosing joint diseases.
In essence, a joint vibration analysis is an important diagnostic tool for detecting even subtle vibrations in the jaw joint. It can offer crucial insights into the condition of the joint and assist in diagnosing 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.
