Abstract
Human chewing movement has been considered to be a cyclic movement with a regular rhythm for each individual. Chewing path, however, has been proved to be changed according to‘sensory input’from various peripheral nervous system (PNS). Analysis of paths of human chewing movements have been known to be useful to find clinical disorder of PNS and to diagnose the mandibular function and evaluate the prosthodontic appliances. Analysis of chewing paths for normal dentition adults and favorable full denture wearers have been performed to find and compare the basic data for the functional evaluation.
From results of this study, the chewing paths of full denture wearers with good retentive and balancing denture were found to be similar to those of normal dentition adults except delay of the cycle time according to extension of the closing phase and tendency to reduce maximum lateral movement.
