Abstract

Author examined the chewing patterns between the 16 normal subjects and the 10 complete denture wearers with LED mandibular tracking device, and analized the chewing envelope and opening, closing velocity during chewing various test foods-standardized carrot, ham and almond. The results were as follows; 1. The chewing envelope of carrot chewing was greater than that of ham chewing in both groups. 2. The average opening velocity was faster than the average closing velocity in both groups. 3. During chewing carrot or almond, the chewing envelope of dentate stoup was greater than that of denture group, but during chewing ham, there was no statistical difference. 4. During chewing carrot or almond the average opening and closing velocity in dentate group were faster than those of denture group.
