Method for bonding dental veneers and restorations
The invention relates to dental composites and porcelain repair material and to methods for making and using them. In particular, the present invention is directed to dual-cure composite dental cements comprising opaquing agents.
1 . A method of bonding porcelain veneers or restorations to a tooth comprising:
applying a resin comprising an opaquing agent to the surface of a tooth, and
applying a veneer or restoration to the resin.
2 . The method of claim 1 , wherein the resin is light curable.
3 . The method of claim 1 , wherein the opaquing agent is titanium dioxide.
4 . The method of claim 1 , wherein the resin comprises a free-radical initiator.
5 . The method of claim 4 , wherein the free-radical initiator is benzoyl peroxide.
6 . The method of claim 1 , wherein hard tissue has not been removed from the tooth.
7 . The method of claim 1 , wherein the composite resin cement is a dual-cure composite resin.
8 . A dual-cure composite resin cement comprising an opaquing agent.
9 . The composite resin cement of claim 8 , wherein the composite resin cement is light curable.
10 . The composite resin cement of claim 8 , wherein the composite resin cement comprises a free-radical initiator.
11 . The composite resin cement of claim 8 , wherein the opaquing agent is titanium dioxide.
12 . The composite resin cement of claim 11 , wherein the composite resin cement is light curable.
13 . The composite resin cement of claim 11 , wherein the composite resin cement comprises a free-radical initiator.
14 . The composite resin cement of claim 8 , wherein the composite resin cement is of a shade that matches a shade on the Vita™shade guide.
15 . A method of bonding porcelain veneers or restorations to a tooth comprising:
applying a composite resin cement to the enamel of a tooth, and
applying a veneer or restoration to the resin,
wherein the composite resin cement comprises an opaquing agent.
16 . The method of claim 15 , wherein the opaquing agent is titanium dioxide.
17 . The method of claim 16 , wherein the composite resin cement is light curable.
18 . The method of claim 16 , wherein the composite resin cement comprises a free-radical initiator.
19 . A method of bonding porcelain veneers or restorations to a tooth comprising:
applying a composite resin cement to the enamel of a tooth, and
applying a veneer or restoration to the resin,
wherein the composite resin cement is a dual-cured cement and comprises an opaquing agent.
20 . The method of claim 19 , wherein the opaquing agent is titanium dioxide.
