[Evaluation of the treatment effect for bruxism by using myomonitor and occlusal splint].
OBJECTIVE: To evaluate the treatment effect of bruxism by using myomonitor and occlusal splint therapy. METHODS: By using EMG, audiocontrolled recorder and myollectronic recording device to record and analyse the muscles functional state before and after treatment. RESULTS: Splint therapy was more effective than the myomonitor did, such as teeth grinding stopped in 12 cases to 1 case, grinding time decreased in 13 cases to 10 cases and no significant effect in 2 cases to 17 cases. SPD and V/T curve slope of muscles decreased. CONCLUSION: This indicates that the functional state of masticatory muscles got improved. Splint therapy is one of the effective treatment method for bruxism.
