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 dysfunstion symptoms during 45minutes or above. The author observed velocities of mandibular opening end closing movement, variabilities, of mandibular rest position and EMG activities of temporal and masseter muscles.
1. There was no significant differences on velocities of mandibular opening and closin movement between before and after Myo-monitoring..
2 There were significant differences on vertical dimension and total dimension from 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 masster muscles were decreased in Myo-monitoring.
4. There were disappeared significant differences on EMG activity values between nomal and symptom groups after Myo-monitoring.
