[INVESTIATION OF ELECTROMYOGRAPHIC ACTIVITY OF TEMPORAL AND MASSETER MUSCLES AFTER ORTHODONTIC TREATMENT OF MALOCCLUSION COMPLICATED BY DENTAL CROWDING].
The results of investigation showed that it is necessary to use complex methods of orthodontic treatment in patients with malocclusion complicated by dental crowding. Orthodontic appliance therapy should be accompanied by differentiated massage and mioymnastics to improve functional state of masseter and temporal muscles. It was found that after the treatment electromyographic potential amplitude of temporal muscles is on the average in 1.5 times lower as compared with pretreatment records (P < 0.05). It was observed increase on the average in 1.5 times in electromyographic potential oscillation amplitude of masseter muscles during clenching after the treatment of maxillary and mandibular dental crowding (P < 0.05). Treatment of dental crowding resulted in restoration of masseter muscles functional symmetry. During clenching index MASI(MM) significantly decreased in all groups in comparison with pretreatment indices (P < 0.05).
