Abstract
INTRODUCTION. There is an analysis of the bioelectric potential indicators of muscles based on electromyographic study data was conducted in patients with gnathic forms of mesial and distal occlusions before and after combined treatment in this article.
AIM. To analyze the bioelectric potential indicators of muscles in the examination of patients with gnathic forms of mesial and distal occlusion based on electromyographic study data.
MATERIALS AND METHODS. As part of this work, 40 patients at the age of 18 to 44 with gnathic forms of mesial occlusion were examined before and after undergoing orthognathic surgery. A comparative analysis was conducted with data obtained by E.B. Castaño in 2019 from the study of patients with gnathic forms of distal occlusion.
RESULTS. After analyzing electromyographic study during the “Initial Contact of Teeth” test showed that all patients with skeletal forms of mesial occlusion exhibited significantly elevated readings compared to those with distal occlusion, indicating an increased tone in the activity of all muscle groups in the craniofacial region. This condition persists even after the combined treatment. Additionally, lower values were observed in the “Maximum Contact of Teeth” test across both study groups; however, during post-treatment, the muscles experience less strain in patients with skeletal forms of distal occlusion.
CONCLUSIONS. Аdult patients aged 18 to 44 years, the study revealed significant differences in the increase of specific indicators both before and after treatment. This indicates considerable muscle overload at all stages of treatment. When treating adult patients with skeletal forms of occlusal anomalies, it is essential to consider electromyographic findings to create conditions for the proper functioning of the dental and jaw system upon completion of treatment and to guide rehabilitation strategies.
