초록 ▼

Presently described are dental compositions comprising one or more fatty mono(meth)acrylates, methods of use, dental articles, and methods of making dental compositions. It has been found that a relatively low concentration of a fatty mono(meth)acrylate can improve the handling characteristics of a dental composition by reducing the tendency of the composition to stick to a dental instrument and/or by reducing the tendency of a dental composition to string when being manipulated by a dental instrument. In one embodiment, a hardenable dental composition is described comprising a polymerizable resin composition comprising at least one multifunctional ethylenically unsaturated monomer; 0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; and at least 50 wt-% of inorganic oxide filler.

1. A hardenable dental composition comprising: a polymerizable resin composition comprising at least one multifunctional ethylenically unsaturated monomer;0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; andat least 50 wt-% of inorganic oxide filler,wherein the fatty mono(meth)acrylate monomer is phase separated from the polymerizable resin composition such that the fatty mono(meth)acrylate monomer is in the form of microscopic domains. 2. The hardenable dental composition of claim 1 wherein the hardenable dental composition can be shaped with an instrument without substantially stringing. 3. The hardenable dental composition of the claim 1 wherein the fatty mono(meth)acrylate monomer comprises an alkyl group having greater than 12 carbon atoms. 4. The hardenable dental composition of the claim 1 wherein the fatty mono(meth)acrylate monomer comprises an alkyl group having 6 to 12 carbon atoms. 5. The hardenable dental composition of claim 1 wherein the inorganic oxide filler comprises nanoparticles. 6. The hardenable dental composition of claim 5 wherein the nanoparticles comprise silica, zirconia, or mixtures thereof. 7. The hardenable dental composition of claim 5 wherein the nanoparticles are in the form of nanoclusters. 8. The hardenable dental composition of claim 5 wherein hardenable dental composition can be extruded through an orifice with a force no greater than 20 kg for an orifice diameter of 2 mm. 9. The hardenable dental composition of claim 1 wherein the fatty mono(meth)acrylate increases the contrast ratio of the hardenable dental composition by at least 5. 10. The hardenable dental composition of claim 1 wherein the hardenable dental composition has a contrast ratio of at least 45 and is free of opacifying pigment. 11. The hardenable dental composition of claim 1 wherein the hardenable dental composition has a ratio of contrast ratio to depth of cure of at least 10. 12. The hardenable dental composition of claim 1 wherein the polymerizable resin composition comprises one or more ethylenically unsaturated monomers selected from the group consisting of isocyanurate monomers, ethoxylated resorcinol monomers, and mixtures thereof. 13. The hardenable dental composition of claim 1 wherein the polymerizable resin composition comprises an addition-fragmentation agent. 14. The hardenable dental composition of claim 1 wherein the polymerizable resin composition comprises at least one monomer selected from the group consisting of ethoxylated bisphenol A dimethacrylate (BisEMA6), bisphenol A diglycidyl dimethacrylate (bisGMA), urethane dimethacrylate (UDMA), and polyethyleneglycol dimethacrylate (PEGDMA). 15. A dental article comprising the hardenable dental composition of claim 1 at least partially hardened. 16. A hardened dental composition comprising: a polymerized resin composition comprising at least one multifunctional ethylenically unsaturated monomer;0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; andat least 50 wt-% of inorganic oxide filler,wherein the fatty mono(meth)acrylate monomer is phase separated from the polymerized resin composition such that the fatty mono(meth)acrylate monomer is in the form of microscopic domains.
