Abstract: An alloy and method is disclosed for forming an improved dental prosthesis. The invention relates to a dental material of a precious metal composition and a method for infiltrating one alloy with another to produce a substructure for ceramic prosthetic restorations for damaged or missing teeth or metal replacements for same.

Abstract: The specification discloses a tooth-shaped member including a central insert which is removable from a facing in order to make the supporting framework for a dental bridge. An appropriate size and shape of a tooth-shaped member is selected and aligned in a gap between built up wax crowns of abutment teeth. The insert extends across the facing and is adhesively bonded at the ends thereof to the adjacent wax crowns. The facing is then removed from the insert. The wax crowns are cut down to the desired shape and the insert and crowns are removed as a single unit. The unit is then cast to form a bridge framework which is coated with porcelain to form artificial teeth.
