Estudo eletromiografico (de superficie) de musculos da mastigação em pacientes com e sem disfunção temporomandibular antes e depois do tratamento da cirurgia ortognatica

TL;DRAbstract

Dentofacial deformities are alterations in hard and soft tissues that cold be result from genetic or environmental influences. Orthognathic surgery aims to demonstrate the improvement of the esthetic and functional deficits after surgery. The objectives were (1) to assess physical and funcional activity (EMG) in rest and isometric (2) evaluate the presence of painful symptoms before and after surgery (3) to assess the symmetry of masticatory`s muscles in different jaw movements (isotonic and isometric). For the evaluation of painful symptoms was used questionnaire RDC / TMD axis I and II. The electromyographic were performed in all patients in the masseter and temporal muscles bilaterally during rest, isotonic and isometric. After the qualitative analysis of the signal, the variables were selected are: amplitude (Root Mean Square (RMS)) and Symmetry. These assessments were performed before treatment (2 to 3 months) and after surgical treatment (2 and 6 months).
