BTS TMJOINT is a solution for the functional analysis of the dental occlusion. By the electromyographic analysis, allows measuring the differential influence of the occlusal function through indices validated and published in scientific literature. Functional information is provided on the neuromuscular alterations induced by occlusal contact. Special feature of this system is the standardization of the electromyographic signal that is provided by the comparison between two test of clenching, done with and without the interposition of cotton rolls between the dental arches. This method allows the elimination of problems of the wrong positioning of the electrodes, of the difference of impedance of the patient’s skin, of the differences of muscular tropism, etc. making it accurate and repeatable. The results are shown via a special graphic interface that is easy to understand for both the physician and patient.
