K7 Evaluation System

Dr. Hoa Nguyen - K7 Evaluation system

The ULF – TENS unit relaxes the muscles that are used by the Temporomandibular Joint (TMJ). That notwithstanding, by using the Myotronics TENS unit alone, we cannot be absolutely certain that the muscles are in a completely relaxed state (which is essential to identifying the optimal occlusion or bite). It is for that reason that Dr. Nguyen highly recommends verifying the prescribed occlusal orientation with the K7 Evaluation System before proceeding with any treatment plan.

The Myotronics K7 Evaluation System provides Dr. Nguyen with objective measurements of the mandibular path of closure, muscle activity and the amount of vibration that occurs when opening and closing. Using a thorough analysis of the data that the system collects, he can identify with a fair degree of certainty what occlusal position is in fact optimal.

The data collection using the Myotronics K7 Evaluation System typically occurs at several different junctures before, during and after treatment. First, the measurements are taken before the ULF – TENS unit is used. This establishes a baseline measurement of the mandibular path of closure, muscle activity when the jaw is closed and the vibration that occurs when opening and closing. Once these baseline measurements are taken, the ULF - TENS unit is used to relax the muscles and hopefully set the jaw into a completely relaxed state. The measurements are taken again and compared to the baseline results as well as optimal indicators. Adjustments or additional “TENSing” may be required in order to identify the exact optimal occlusion.

It is at this point of the diagnostic phase that a fundamental difference between the Neuromuscular and Gneuromuscular approach appears. Dentists that adopt the Neuromuscular approach are confident that the position of the jaw that is induced when the muscles are completely relaxed is the optimal position. Although treatment can be successful using this approach, there are instances when the optimal position of the jaw is not accurately diagnosed and as a result, the symptoms sometimes subside only temporarily or do not disappear completely.

Dentists, including Dr. Nguyen, trained in the Gneuromuscular approach feel that it is important to help the jaw, through expert manipulation, “find” its optimal place (once the constraints of tense muscles are no longer a concern). Dr. Nguyen will gently extend the jaw’s position, and slowly release it back into its natural state while using the K7 Evaluation System. Ultimately, as this process is repeated, the naturally optimum occlusion is identified through the system’s readings.

Once the optimal occlusion is empirically identified, Dr. Nguyen will then establish treatment plan options that will help maintain the healthy position of the Temporomandibular jaw.
