RESUMO

Analysis of eletromiographic function of the mouth superior and inferior orbicular muscles, middle portion and mentonian in young patients with malocclusion class li, division 1 according to Angle with and without an ortopedic functional device of BIMLER. For This purpose 5 patients were selected, 1 male and 4 female with ages between 10 and 12. Muscular eletromiography activities were measured in usual oclussion and while swallowing saliva in the periods of 1 day, 1 week, 1 month, 3 months and 6 months. Data were submitted to varation analysis and results compared two by two according to Tukey. Iso the frequency distribution based in a intensity levels scale in microvolts according to Basmajian (, 1974 ) was made. Results showed significant differents in the activity of moutt1 orbicular muscle, middle portion, superior and inferior segments among the patients class 11, division 1 according to Angle while wearing the device, the inferior segment has a more effective function in relation to the superior orbicular muscle, as in usual occlusion as while swallowing saliva; in this period patients showed a very strong mentonian muscle and inferior segment of mouth orbicular activity. The studied muscles showed that in usual occlusion and with the device, electrial activltjes increase in the first month and decrease a lot in the 3rd and 6th month of use. Patients IIÍthout the BIMLER functional device showed action potentials smaller tha" the ones with the device, in ali the periods studied. There is a tendency to adapt the electrial activity from peribucal muscles ( superior and inferior o,picular and mentonian ) after the 6th month of use of the BIMLER functional device.
