Effectiveness evaluation of the interdisciplinary approach in the treatment of patients with iatrogenic functional disorders of the maxillofacial area associated with primary deep bite according to the dynamics of changes in electromyographic studies

The aim of our work is to improve the quality of comprehensive orthodontic treatment by searching for the most favorable conditions and terms necessary for the implementation of the adaptive capacity of the body at the stages of reconstructive manipulations in patients with occlusal disorders of the dentofacial system resulting from dental interventions.Material and methods. A prospective group clinical study was carried out. Groups were formed due to the total clinical sample of 105 patients, age range 18-45 years (mean age 29.9±6.1 years) with iatrogenic functional prosthetic disorders complicated with a primary deep bite. Three clinical groups were identified. The first included 37 patients with predominantly muscular symptoms, the second - 42 patients with dysfunction of the temporomandibular joints, and the third included 26 patients who, in addition to muscle and / or joint symptoms, had primary neurogenic disorders. In order to compare the effectiveness of treatment, each of the clinical groups was divided into 2 subgroups depending on the treatment algorithm used; namely, the first subgroup included patients who were treated according to the scheme developed by us, and the second subgroup included patients treated according to the generally accepted method.Results. There was a decrease in the amplitude of bioelectrical activity and a reduction in the time of the activity period, and, accordingly, the approximation of the activity coefficient to one in patients with vertical abnormalities, aggravated by crowding of the teeth, occurred already at the stage of splint therapy.Conclusions. Our studies allow us to predict both the duration of treatment and the amount of occlusal correction combined with the reconstruction of the position of the lower jaw and the improvement of the general somatic state of the patient's body.
