BioEMG III™ Bio-Metric Instrument

Surface EMG is the worldwide standard method for recording muscle-specific activity in skeletal muscles. It has been proven reliable in numerous studies over many years and is a clinical procedure that can easily be performed in any dental office. This information is invaluable to the clinician that hopes to create beautiful dentistry that works with the patients physiology for optimum results.

BioEMG III is specifically designed to record craniofacial muscle activity in both rest and function. This information is invaluable to the clinician who hopes to create beautiful dentistry that works with the patient’s physiology for optimum results.

The BioEMG III incorporates intuitive displays that are extremely fast and easy to interpret as compared to conventional systems that simply display the microvolt levels of each channel. Now you can design a system to automatically catagorize muscles based upon the quality and quantity of their behavior. Based upon your thresholds, the system will automatically show which muscles are resting properly or are hyperactive. It provides immediate evaluation of the synergy, symmetry and timing of craniofacial muscle firing to expidite the process of evaluating mandibular muscle function
