Self-etching emulsion dental compositions and methods
View Patent ↗The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.
1. An adhesive composition comprising:
an ethylenically unsaturated compound with acid functionality;
an ethylenically unsaturated compound without acid functionality;
an initiator system;
a surfactant; and
water,
wherein the adhesive composition is a self-etching, water-in-oil emulsion dental adhesive composition, and wherein the adhesive composition comprises inverse micelles.
2. The adhesive composition of claim 1 wherein the acid functionality comprises carboxylic acid functionality, phosphoric acid functionality, phosphonic acid functionality, sulfonic acid functionality, or combinations thereof.
3. The adhesive composition of claim 1 wherein the surfactant is an ethylenically unsaturated compound with acid functionality.
4. The adhesive composition of claim 1 wherein the surfactant is a nonionic surfactant.
5. The adhesive composition of claim 4 wherein the nonionic surfactant is a polymerizable surfactant.
6. The adhesive composition of claim 4 wherein the nonionic surfactant is an ethoxylated alkyl phenol comprising a polymerizable group.
7. The adhesive composition of claim 1 wherein the emulsion is physically stable.
8. The adhesive composition of claim 1 wherein the adhesive composition comprises less than 30% by weight water.
9. The adhesive composition of claim 1 wherein the adhesive composition is a water-in-oil micro-emulsion.
10. The adhesive composition of claim 1 wherein the emulsion is chemically stable.
11. The adhesive composition of claim 1 wherein the adhesive composition further comprises a filler.
12. An adhesive composition comprising:
an ethylenically unsaturated compound with acid functionality;
an ethylenically unsaturated compound without acid functionality;
an initiator system;
a surfactant; and
water,
wherein the surfactant is an ethylenically unsaturated compound with acid functionality, and wherein the adhesive composition is a self-etching, water-in-oil emulsion dental adhesive composition.
13. An adhesive composition comprising:
an ethylenically unsaturated compound with acid functionality;
an ethylenically unsaturated compound without acid functionality;
an initiator system;
a surfactant; and
water,
wherein the surfactant is a nonionic polymerizable surfactant, and wherein the adhesive composition is a self-etching, water-in-oil emulsion dental adhesive composition.
14. An adhesive composition comprising:
an ethylenically unsaturated compound with acid functionality;
an ethylenically unsaturated compound without acid functionality;
an initiator system;
a nonionic surfactant; and
water,
wherein the nonionic surfactant is an ethoxylated alkyl phenol comprising a polymerizable group, and wherein the adhesive composition is a self-etching, water-in-oil emulsion dental adhesive composition.
