Abstract

Complete denture wearers in the normal face group were divided into left and right deviation groups for the frontal dentoskeletal form. The mechanisms of their jaw functions were analyzed in terms ofthe lateralized mastication index and asymmetry index of masticatory muscle EMG activity. Their relationshipwas examined, and the magnitude of bite force was divided into two levels (50% and 100% MC).<BR>The results revealed that the asymmetry index of masticatory muscle EMG activity was strongly relatedto deviation and frequency of the lateralized masticatory index, as well as the mandible in the frontaldentoskeletal form when chewing, during masticatory movement with relatively weaker bite force.
