Abstract

Orthopedic and orthodontic treatment of 49 patients aged 6 to 17 years with dentition defects in the frontal area was examined and performed to conduct and determine the state of the masticatory muscles in children with dentition defects. Patients were divided into two groups depending on the period of formation of the dento-maxillaire system and each of the groups was divided into two subgroups depending on the method of treatment and the mechanism of fixation of the orthodontic appliance in the oral cavity. When comparing the indicators between groups I A and I B, we can state that there were more qualitative and dynamic changes in electromyographic indicators in children of group I B than group I A. When comparing the data received after orthopedic and orthodontic treatment of children in group II, we can state that quantitative and qualitative indicators of electromyography for group II B were better than those of children in group II A. In children who were treated with removable appliances, these indicators improved, but remained at a worse level than in those treated with non-removable appliances.
