Purpose: When edentulous patients do not receive dental treatments, they will have difficulty in pulling the hyoid bone and the larynx to actuate the swallowing reflex as individuals could not achieve a stable jaw position. Bedridden elderly might suffer from an unfavorable feeding posture. The purpose of this study was to evaluate the effects of vertical occlusal dimension and feeding posture on swallowing function.<BR>Methods: Eight totally edentulous subjects (mean age 55.0±10.9) were chosen for the evaluation of lingual/palatal pressure during swallowing, to analyze the effects of feeding posture and edentulism. An experimental apparatus, consisting of an acrylic denture base with soft bite rims, was fabricated to restore two settings (high and low) of vertical occlusal dimensions. Water-repellent pressure sensors (PS-2 Ka, Kyowa Electric Co., Tokyo, Japan) were embedded in the anterior and lateral portions of the acrylic base. Five ml of water was repetitively given for the subjects to swallow in the upright, 30°, and supine positions. Lingual/palatal pressure against the sensors was evaluated by a computerized system. The data were analyzed by Student's t-test and Sheffe's F-test (p<0.05).<BR>Results: The results showed significantly lingual/palatal pressure at the lateral portion when the subjects swallowed without bite rims at the 30° and supine positions, compared with at 90°(p<0.05). The lingual/palatal pressures at the anterior and lateral portions with a bite rim at the 30°and 90° postures showed significant difference between with and without bite rim situations (p<0.05).<BR>Conclusions: It was concluded that the effect of feeding posture was significant for swallowing function in the totally edentulous condition.
