Abstract
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.
