Measuring and recording mandibular function and masticatory muscle status adds invaluable information to the diagnostic process and is critical ton the neuromuscular dentist. Objective information about TM joint status further adds to the clinician's data. Evaluation procedures must be accomplished in such a way that the apparatus itself does not affect the patient's function and must not impede the clinician's access to the mouth for bite registration or other procedures. Myotronics evaluation equipment has always been designed with those criteria in mind.

The K7 Evaluation System provides the neuromuscular dentist or researcher with three technologies for measuring, displaying and storing objective data on physiologic and anatomical status and function: jaw tracking, electromyography and joint sonography. This objective data enhances the doctor's diagnostic and treatment considerations with information not previously available.

K7/CMS Computerized Mandibular Scanner

Multiple sensors in an extremely light weight (four ounce) spectacle-like array, track the motion of a tiny magnet attached to the lower incisal gingiva with adhesive material. The configuration is totally non-invasive and, unlike clutches, does not interfere with patient function. The opposing sensors are wide apart permitting unobstructed access to the oral cavity for taking bite registrations and other clinical procedures, and the system is virtually immune from effects of slight head motion or nearby metallic or electronic interference. A patient education mode is included to simplify patient understanding and staff training.

These scans are invaluable three dimensional representation of mandibular rest, the relaxed neuromuscular path of closure, centric occlusion, habitual path of closure and protrusive guidance that aids the neuromuscular dentist in recording an optimal occlusal position.

K7/CMS Eight Channel Electromyograph

Utilizing high quality bipolar surface electrodes, surface EMG data can be taken from up to eight muscle sites simultaneously and in real time. The program permits taking electromyography data either at rest or in function. All eight channels may be displayed simultaneously, for a period of 15 seconds (one visual screen width). The K7/EMG signal processing circuitry provides unsurpassed protection against system noise or motion artifact. The patient education mode permits quick and easy patient education as to status of masticatory muscles.

These scans provide an objective measurement of masticatory muscle electrical activity which accurately represents their physiologic state.

K7/CMS Electrosonograph

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 neuromuscular dentists' with valuable information to aid in assessing the status of articular disk and joint function.

The ESG includes the ability to document TM joint status through recording joint sound vibrations – simply and non-invasively.
