Abstract

PURPOSE: To fire porcelain and metal firmly by ordinary techniques by constituting a desired shape with the porcelain and wax, embedding the entire part in an investment compound, burning or evaporating the wax in the furnace and pouring molten metal in the space created by this.
CONSTITUTION: The lower part of an existing porcelain tooth 1 is cut in conformity with the tooth germ of the patient, and the tooth 1 and the germ 3 are fitted well at parting faces. Next, the space constituted by the tooth 1, the germ 3 and a root filling material 4 is waxed up with wax 6, whereby the shape for one piece of tooth is formed. Next, a sprue 8 is mounted at about 45° angle to the axial line 7 of the tooth. After the dental prosthesis crown part constituted by the three of the tooth 1, the wax 6, and the sprue 8 is removed from the germ 3, it is set in a centrifugal casting device. The dental prosthesis crown part is embedded with an investment compound 9 in such a way that the sprue 8 aligns to a molten metal teeming port 13. After the solidification of the compound 9, the assembly is put in a furnace and the wax 6 is burned or evaporated. Molten metal is teemed into the space created by this through the port 13 and the sprue 8, and the tooth 1 and the metal are fired.
