TMJ Vibration (Sound) Evaluation System. A lightweight headset holds highly sensitive vibration transducers over each TM joint, enabling simultaneous, bilateral capture of tissue vibrations emanating from joint sounds. Vibration (sound) data is correlated to vertical dimension of opening and closing, providing clinicians with valuable information to aid in assessing the status of articular disk and joint function.
The ESG provides the ability to objectively document TM joint status through recording joint sound vibrations – simply and non-invasively.
