Abstract

Abstract A dental prosthesis of the type secured to the alveolar ridge within the mouth of the user through the application of a partial vacuum which serves to stabilize and maintain a dental plate in secure operative position. A full or partial dental plate incorporates false teeth at least some of which have a hollow interior portion in which valve means are mounted in fluid communication with a pressure differential channel itself extending along and being disposed in fluid communication with exposed surface portions of the alveolar ridge. Application of negative pressure to the interior of the mouth serves to direct fluid flow from the differential pressure channel through the valving structure within the hollow interior portion wherein such valving structure prohibits reverse flow therethrough. A partial vacuum is thereby created and maintained between the undersurface of the dental plate, in the area of the differential pressure channel, and the exposed surface of the alveolar ridge.
