Abstract

In order to evaluate the influences of Myo-monitoring on masticatory muscles, Myo-monitoring on 31 normal persons and 30 persons with one more temporomandibular dysfunction symptoms during 45 minutes or above. The author observed velocities of mandibular opening and closing movement, variabilities of mandibular rest position and EMG activities of temporal and masseter muscles. The obtained results were as follows : 1. There were no significant differences on velocities of mandibular opening and closing movement between before and after Myo-monitoring. 2. There were significant differences on vertical dimension and total dimension form mandibular rest position to centric occlusion between before and after Myo-monitoring but no significant differences on anteroposterior and lateral dimension. 3. Activities of temporal and masseter muscles were decreased in Myo-Monitoring. 4. There were disappeared significant differences on EMG activity values between normal and symptom groups after myo-monitoring.
