Abstract
Abstract A glazing device, and a method for using such device to apply a surface glaze to a dental construct. The device includes glazing material associated with a shrinkable, hollow carrier. The method includes 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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
94 words
A method of glazing a dental construct having a complex surface which comprises associating glazing material with a carrier in the form of a hollow, open-ended enclosure, the carrier being composed of a shrinkable and removable organic material, assembling the construct and carrier so that the construct is positioned within the carrier, subjecting the assembly to a treatment to shrink the carrier into intimate contact with the construct surface, removing the organic carrier to leave the glazing material on the construct surface, and maturing the glazing material to a glaze on the construct surface.
Claim 2
Independent Claim
94 words
A method of glazing a dental construct having a complex surface which comprises associating glazing material with a carrier in the form of a hollow, open-ended enclosure, the carrier being composed of a shrinkable and removable organic material, assembling the construct and carrier so that the construct is positioned within the carrier, subjecting the assembly to a treatment to shrink the carrier into intimate contact with the construct surface, removing the organic carrier to leave the glazing material on the construct surface, and maturing the glazing material to a glaze on the construct surface.
Claim 3
Dependent Claim
17 words
A method in accordance with claim 1 wherein the dental construct is formed from a glass-ceramic material.
Claim 4
Dependent Claim
14 words
A method in accordance with claim 2 wherein the glass-ceramic is a tetrasilicic fluormica.
Claim 5
Dependent Claim
21 words
A method is accordance with claim 1 wherein the dental construct is formed at least in part of a dental porcelain.
Claim 6
Dependent Claim
17 words
A method in accordance with claim 1 wherein the dental construct is formed from a ceramic material.
Claim 7
Dependent Claim
17 words
A method in accordance with claim 1 wherein the dental construct is formed from an organic material.
Claim 8
Dependent Claim
18 words
A method in accordance with claim 1 wherein the dental construct is formed from a blank by milling.
Claim 9
Dependent Claim
13 words
A method in accordance with claim 1 wherein the carrier is thermally shrinkable.
Claim 10
Dependent Claim
16 words
A method in accordance with claim 1 wherein the organic carrier is removed by thermal treatment.
Claim 11
Dependent Claim
15 words
A method in accordance with claim 1 wherein the organic carrier is removed by volatilization.
Claim 12
Dependent Claim
15 words
A method in accordance with claim 1 wherein the organic carrier is removed by oxidation.
Claim 13
Dependent Claim
19 words
A method in accordance with claim 1 wherein the glazing material is in the form of vitreous glaze particles.
Claim 14
Dependent Claim
25 words
A method in accordance with claim 12 wherein the glaze particles are associated with the carrier by application to the inside wall of the carrier.
Claim 15
Dependent Claim
26 words
A method in accordance with claim 12 wherein the glaze particles are associated with the carrier by intermingling the particles with the body of the carrier.
Claim 16
Dependent Claim
23 words
A method in accordance with claim 12 wherein the glaze particles are admixed with one or more pigments to form a coloration pattern.
Claim 17
Dependent Claim
25 words
A method in accordance with claim 15 wherein the coloration pattern is associated with the carrier by application to the inside wall of the carrier.
Claim 18
Dependent Claim
29 words
A method in accordance with claim 15 wherein the coloration pattern is associated with the carrier by intermingling the particles of the pattern with the body of the carrier.
Claim 19
Dependent Claim
16 words
A method in accordance with claim 15 wherein the coloration pattern is graduated across the carrier.
Claim 20
Dependent Claim
28 words
A method in accordance with claim 18 wherein the amount of pigment in the coloration pattern varies from the closed end of the carrier to the open end.
Claim 21
Dependent Claim
19 words
A method in accordance with claim 1 wherein the glazing material is in the form of curable organic materials.
