US 2014/0234802 A1 · MOLDING ARTIFICIAL TEETH IN DENTURE BASE DISC

Abstract

A method of molding artificial teeth in denture base material comprising forming a U-shaped cavity in a block of denture base material, forming socket cavities in the bottom of the U-shaped cavity, casting a fluid artificial tooth material into the cavities, and causing the fluid tooth material to solidify into solid artificial tooth material while applying pressure. Causing the solidification may include heating the fluid tooth material. The method may include casting a liquid elastomer into a bottom portion of the U-shaped cavity following forming that cavity and prior to the forming the socket cavities, curing the liquid elastomer into a solid elastomeric cushion, and removing the cushion from the U-shaped cavity. Subsequently, the cushion may be inserted into the U-shaped cavity and contacted with the fluid tooth material. A die may then be contacted with the cushion to apply pressure to it and the fluid tooth material during curing.

Dependent claims

A method of molding artificial teeth in a denture base material, the method comprising:

a) forming a first cavity in a block of a denture base material, the first cavity having a bottom wall and a side wall and formed to correspond to the U-shaped contour of natural teeth as arranged on maxillae or on a mandible;
b) forming a plurality of socket cavities in the block of denture base material, the socket cavities extending downwardly from the bottom wall into the denture base material;
c) casting a first fluid artificial tooth material into the plurality of socket cavities and into a portion of the first cavity, thereby filling the socket cavities and forming a top fluid surface in the first cavity;
d) applying pressure to the first fluid artificial tooth material contained in the portion of the first cavity and the socket cavities;
and
e) causing the first fluid artificial tooth material to solidify into a first solid artificial tooth material while applying pressure to the first fluid artificial tooth material.
