WHAT Is Electrosonography (ESG)?
ESG is most commonly called “sonography” and sometimes “joint vibration analysis”. It utilizes computer based vibration sensitive transducer technology that quickly and non-invasively records joint sounds and vibrations originating in the temporomandibular (TM) joints. The patient wears a lightweight headset that positions two sensors over the joints. The technician instructs the patient to open and close, and in just a few minutes valuable information about joint function is captured for analysis.
