In the present invention dental prostheses are cured without the use of dental flasks using an electrically heated pressure vessel. The dental prosthesis is cured while in a plaster chamber which is placed in a curing container with ambient water. The apparatus includes a perforated table for supporting the curing container during heat curing. The vessel has a lid for sealing the top, an inlet for injection of compressed air, an outlet for exhausting of compressed air, and an electrical resistance heating means for heating water held in the vessel. The curing container holds ambient temperature water at a level which covers the plaster chamber prior to submerging the curing container in the vessel containing water at a temperature of 90°C. to 100°C. The table supports the outing container in the vessel so that the top edge of the curing container is above the level of water held by the vessel. The present invention provides that the plaster chambers with the dental prosthesis inside of it being already aggregated heat curing acrylic, are those which maintain the vertical dimension. They are within the curing container while they are gradually heated by the hot water of the processor. Pressure which could fracture the model and the prosthesis is avoided.
