Outline of Final Research Achievements

The purpose of this study was to evaluate to the effect of masticatory movements on head, trunk and body sways during standing position. When subjects maintained standing position with masticating chewing gum, head, trunk and body sways were significantly smaller than when they maintained their mandibles in the rest position and centric occlusion (p<0.05). No significant differences were found in the weight distribution between the 2 mandibular positions and masticating chewing gum. It was founded that masticating chewing gum affected the stability of head, trunk and body sways during standing position. These findings suggest that masticatory movements affect the postural control by enhancing the postural stability during standing position.
