Abstract

To provide a dental primer previously applied for strongly bonding a dental restoration made of various kinds of materials to dentine in a dental treatment field, and a dental adhesive set comprised of the dental primer and a dental adhesive having high dentine adhesiveness when used with the dental primer, the dental primer includes (meth)acrylate having an acid group, water, a water-soluble volatile organic solvent, and a vanadium compound, and can further include a filler and (meth)acrylate not having an acid group, while the dental adhesive set is comprised of the dental primer and a dental adhesive which includes (meth)acrylate having an acid group, (meth)acrylate not having an acid group, hydroperoxide as a polymerization initiator, a thiourea derivative as a reducing agent, and a vanadium compound as a polymerization accelerator, and can further include a filler.

Claims

1. A dental primer comprising (meth)acrylate having an acid group, water, a water-soluble volatile organic solvent, and a vanadium compound.

2. The dental primer as claimed in claim 1, wherein the dental primer comprises 3 to 35% by weight of the (meth)acrylate having an acid group, 5 to 70% by weight of the water, 20 to 80% by weight of the water-soluble volatile organic solvent, and 0.001 to 1% by weight of the vanadium compound.

3. The dental primer as claimed in claim 1 or 2, wherein the dental primer further comprises a filler and/or (meth)acrylate not having an acid group.

4. The dental primer as claimed in claim 3, wherein a blending ratio of the filler is 0.5 to 50% by weight, and a blending ratio of the (meth)acrylate not having an acid group is 5 to 25% by weight.

5. The dental primer as claimed in claim 1, wherein the vanadium compound is one or more kinds selected from vanadium acetylacetonate, vanadyl acetylacetonate, vanadyl stearate, vanadium naphthenate, and vanadium benzoyl acetonate.

6. A dental adhesive set comprising:

the dental primer as claimed in claim 1 or 2; and

a dental adhesive comprised of (meth)acrylate having an acid group, (meth)acrylate not having an acid group, hydroperoxide as a polymerization initiator, a thiourea derivative as a reducing agent, and a vanadium compound as a polymerization accelerator.

7. The dental adhesive set as claimed in claim 6, wherein the dental adhesive comprises:

7 to 60% by weight of the (meth)acrylate not having an acid group;

3 to 30% by weight of the (meth)acrylate having an acid group;

0.01 to 10% by weight of the hydroperoxide as a polymerization initiator;

0.01 to 10% by weight of the thiourea derivative as a reducing agent; and

0.001 to 5% by weight of the vanadium compound.

8. The dental adhesive set as claimed in claim 6, wherein the dental adhesive further comprises a filler.

9. The dental adhesive set as claimed in claim 7, wherein the dental adhesive further comprises a filler.

10. The dental adhesive set as claimed in claim 8, wherein a blending ratio of the filler in the dental adhesive is 0.5 to 80% by weight.

11. The dental adhesive set as claimed in claim 9, wherein a blending ratio of the filler in the dental adhesive is 0.5 to 80% by weight.

12. The dental adhesive set as claimed in claim 6, wherein the vanadium compound in the dental adhesive set is one or more kinds selected from vanadium acetylacetonate, vanadyl acetylacetonate, vanadyl stearate, vanadium naphthenate, and vanadium benzoyl acetonate.
