  • Glazing dental constructs
    Patent number: 5089306
    Abstract: A glazing device, and a method for using such device to apply a surface glaze to a dental construct, are disclosed. The device comprises glazing material associated with a shrinkable, hollow carrier. The method comprises associating glazing material with a hollow carrier composed of a shrinkable and removable material, assembling the construct and carrier with the construct positioned within the carrier, shrinking the carrier onto the construct, removing the carrier, and maturing the material to a glaze. The device and method find particular application in applying coloration, either uniformly or in a pattern, to a dental construct.
    Type: Grant

  • Glazing dental constructs
    Patent number: 5024790
    Abstract: A method of applying a surface glaze to a dental construct. The method includes associating glazing material with a carrier composed of a highly flexible and removable material, assembling the construct and carrier with the construct positioned within the carrier, forcing the carrier onto the construct by differential fluid pressure, removing the carrier, and maturing the glazing material to a glaze. The method finds particular application in applying coloration, either uniformly or in a pattern, to a dental construct.
