For the purpose of clarifying the functions of each articulator following the insertion of a denture and the state of self-compensation of these organ, the experimental palatal plates were inserted on 13 subjects with natural dentition, assuming that they were inserted with complete denture. The muscular discharge of facial muscles and the tongue pressure of each subject during pronunciation following the insertion was evaluated longitudinally with the pre-insertion of a palatal plate as basis.
As the result of this study, the following conclusions were obtained. The results of this study clearly showed that the lips and the tongue, major articulators, come under the influence by insertion of the denture. They appear to adapt to the new oral cavity environment earlier than before pronunciation.
