ABSTRACT:
One form of artificial modular denture, and the method of producing same, includes an assembly of hard prosthetic teeth permanently secured to a U-shaped hard base structure with a terminus of the hard base structure disposed a short distance rearwardly of the incisor areas of the assembly of the prosthetic teeth, with a palatal vault member adapted to substantially conform with the palatal vault area of the patient's mouth being fitted with the artificial denture. The palatal vault member being selected from a set of palatal vault members having differently contoured configurations, and retaining means is provided for individually releasably connecting the palatal vault members to the assembly so as to permit the selection of the most suitably fitting one of the set of palatal vault members for use as part of the artificial denture.
Another form of artificial modular denture, and the method of producing same, includes a palatal vault member being formed only of deflectibly formable material and capable of being easily deflectibly formed upwardly and set into closely conforming relation with any one of a variety of different palatal vault areas of human mouths for preliminary impression forming of said palatal vault member in any one of several different human mouths. The palatal vault member being removably connected to the base, with the removably connected relationship capable of sustaining the forces applied to the palatal vault member by an uncured hardenably hard liner material in fluid form provided on the palatal vault member and the base recess during insertion in the patient's mouth and forming of the hard uncured material into impression conformance with the palatal vault member and the toothless gum area of the patient's mouth to form a hard liner.
