Abstract
An improved denture having a gum simulating base with a curved recess therein configured to fit the alveolar ridge of a user with simulated teeth supported by the base, some of the teeth having exposed chewing surfaces and an elongated chew enhancing bar of thin metal positioned within adjacent teeth having chewing surfaces, the bar having a generally rectangular cross-sectional configuration with opposed first and second longitudinal edges, the bar first longitudinal edge being exposed at the chewing surfaces of at least three adjacent teeth.
Claims4
An improved denture comprising:
- a gum simulating base having a curved recess therein configured to fit the alveolar ridge of a user;
- simulated teeth supported by said base, the teeth being arranged in a pattern corresponding to the typical arrangement of naturally occurring teeth in which the denture is substantially symmetrical about a plane perpendicular to a plane of said base dividing said teeth into opposed left and right hand portions, the simulated teeth of each portion including two premolars and at least first and a second molars, the first of the molars being adjacent the two premolars, the two premolars and the first, adjacent molar having exposed chewing surfaces;
- and
- an elongated chew enhancing bar of thin metal, the bar having a generally rectangular cross-sectional configuration with opposed first and second longitudinal edges and opposed ends, the bar being positioned within only said two premolars and said first, adjacent molar with the first longitudinal edge of the bar being exposed at the said chewing surfaces and said second molar being free of said bar.
A subassembly for use by a dental technician to make a denture for a patient comprising:
- an integral casting simulating only two premolars and a single adjacent molar, each tooth having a chewing surface, and having embedded therein an elongated chew enhancing bar of thin metal, the bar having a generally rectangular cross-sectional configuration with opposed first and second longitudinal edges and opposed ends, the bar being positioned within only said single two premolars and said adjacent molar with said first longitudinal edge of the bar being exposed at the teeth chewing surfaces.
