[Three cases with temporomandibular joint dysfunction syndrome in adolescents whose mandibular are asymmetrical]

We encountered three patients with TMJ dysfunction syndrome in adolescents whose mandibulars were asymmetrical. In two cases, we tried to treat with EMG Biofeedback therapy in order to improve a form and function. The following results were obtained from the progress and result of the treatment. Asymmetry of mandibular causes the functional disharmony of masticatory muscle and it is probable that its asymmetry causes TMJ symptoms. These symptoms are improved with an occlusal splint, occlusal adjustment and occlusal reconstruction. The form does not change with the EMG Biofeedback therapy which is used in order to activate the masseter muscle. The function changed but was not stable.
