EVALUATION OF THE EFFECTIVENESS OF "SPLINT THERAPY" IN PATIENTS WITH MASTICATORY MUSCLE HYPERTENSION

Abstract

The article presents the results of evaluating the effectiveness of "splint therapy" in patients with masticatory muscle hypertension according to the results of EMG and ultrasound. To achieve this goal, 62 patients aged 18 to 44 years with complaints of pain in the TMJ and masticatory muscles were examined. The examined persons were divided into two groups. The first group included 29 patients who underwent deprogramming of the masticatory muscles using a muscle relaxation splint made under conditions of habitual occlusion. The second group consisted of 33 patients who underwent a session of "TENS-therapy" using the "MYO-MONITOR J5" apparatus for deprogramming the masticatory muscles, followed by the manufacture of a muscle relaxation splint on the lower jaw. The evaluation of the treatment performed is fully possible to carry out electromyography of the temporal muscles and Dopplerography of the superficial temporal artery. According to the interference EMG study of patients in all groups, signs of hypertension of the masticatory muscles and asynchrony of their work were revealed. The analysis of the obtained results showed that after the manufacture of sports mouthguards in the first group, the favorable effect of the sports mouthguard is determined, which is expressed in a decrease in the amplitude of biopotentials, however, the asynchrony of muscle activity remains. In the second group, in the participants, the values of the amplitude of the biopotentials of the masticatory muscles were closer to normal values. The analysis of the obtained results showed that after the manufacture of sports mouth guards in the first group, the indicators of linear and volumetric blood flow velocity increased in the first and second groups, however, these indicators in the participants of the second group were close to normal. These techniques allow you to determine muscle tone at the beginning of treatment and over time, thereby helping to determine a more effective method of treatment. Thus, the materials of our study reflect the need to include electromyography and dopplerography in the treatment protocol for patients with TMJ dysfunction.
