| Outline of Final Research Achievements |
The purpose of this study was to examine the relationship between tongue function and morphology of palatal augmentation prosthesis (PAP). Wearing an experimental occlusal splint (+10mm bite height) for increasing oral cavity volume deteriorated swallowing function in volunteers with healthy dentate. Experimental PAPs were attached to restore the damaged function. The PAPs were optically scanned and analyzed three-dimensional morphology. Tongue pressures against the hard palate during swallowing were recorded by the sensor sheet. The thickness of anterior and lateral part of PAPs were statistically correlated with the maximum tongue pressure during swallowing. The decline of tongue pressure and the form of PAP were closely related. It was suggested that the smaller the tongue pressure, the thicker the PAP was required.
