| Outline of Final Research Achievements |
Function of processing the bolus and transportation the water to the pharynx were declining as tongue pressure to palate was decreased by 4 mm increasing of occlusal vertical dimension. On the other hand, function of transportation the saliva to the pharynx were declining, but no significant different was found in processing the bolus by 3 mm narrowing of the width of dental arch.
From the above, mastication and swallowing are affected by the denture form. Inappropriate form of denture disturbs a transportation the bolus to the pharynx and risk of aspiration pneumonia may be increased as the function of the tongue is declines in extreme aged people. It is very important to consider not only the mastication and esthetics but also swallowing in denture fabrication.
