ABSTRACT:
A method for producing a plate denture which includes heating a flask after embedding a wax denture and wax elimination to a temperature for polymerizing a heat-curable resin, the flask being an assembly including a first half shell having a plaster cast with a corresponding mucosal surface and a second half shell having a plaster cast with artificial teeth embedded therein. The method further including placing the heat-curable resin into the heated flask for polymerization while the flask is at an elevated temperature from the heating, and polymerizing the heat-curable resin in the heated flask. Wherein, during the step of heating the first half shell is heated to a higher temperature level in a range of temperature for polymerizing the heat-curable resin while the second half shell is heated to a lower temperature level in the range than the first half shell.
