Presently described are methods of surface treating inorganic oxide particles, hardenable (e.g. dental) compositions comprising a polymerizable resin composition and surface treated particles, as well as surface treated (e.g. nanocluster) inorganic oxide particles, and silane surface treatment compounds. In one embodiment, the method comprises forming a surface treatment compound by reacting a first functional group of a (meth)acrylate monomer having a molecular weight of at least 350 g/mole with a second functional group of a silane compound wherein the first and second functional group react to form a covalent bond; and combining the surface treatment compound with inorganic oxide particles.

1. A method of surface treating inorganic oxide particles comprising: forming a surface treatment compound by reacting a first functional group of a (meth)acrylate monomer having a molecular weight of at least 350 g/mole with a second functional group of a silane compound wherein the first and second functional groups are not free-radically polymerizable groups and react to form a covalent bond; and combining the surface treatment compound with inorganic oxide particles. 2. The method of claim 1 wherein the method is sequential comprising first preparing the surface treatment compound followed by combining the surface treatment compound with the inorganic oxide particles. 3. The method of claim 1 wherein the covalent bond forms a urethane, urea, or amide linkage. 4. The method of claim 1 wherein the surface treatment compound has a molecular weight of at least 600 g/mole. 5. The method of claim 1 wherein the (meth)acrylate monomer has a refractive index of at least 1.50. 6. The method of claim 1 wherein the (meth)acrylate monomer is branched or comprises a cyclic moiety. 7. The method of claim 1 wherein the (meth)acrylate monomer is a multi(meth)acrylate monomer. 8. The method of claim 7 wherein the (meth)acrylate monomer is a multi(meth)acrylate comprises at least three (meth)acrylate groups. 9. The method of claim 1 wherein the (meth)acrylate monomer has the formula wherein each X independently represents an oxygen atom (O) or a nitrogen atom (N); Y and A each independently represent an organic group, m=1 to 5; n=0 to 5; p and q are independently 0 or 1; and R1 and R2 each independently represent H, —C(O)CH═CH2, or —C(O)C(CH3)═CH2; wherein at least one of R1 and R2 is H or at least one Y, A, or X when X is nitrogen comprises the first functional group that reacts to form the covalent bonds with the second functional group of the silane compound. 10. The method of claim 1 wherein the (meth)acrylate monomer is an isocyanurate monomer. 11. The method of claim 10 wherein the (meth)acrylate monomer has the general structure wherein R1, R5, and R6 are independently alkylene, arylene, or alkarylene, optionally including a heteroatom;X, Y, and Z are independently alkylene, arylene, or alkarylene linking groups, comprising a heteroatom;R3 is independently hydrogen, alkyl, aryl, or alkaryl, optionally including a heteroatom; andR2 is hydrogen or methyl;wherein at least one of R1, R3, R5, R6, X, Y, and Z comprises the first functional group that reacts to form the covalently bonds with a second functional group of the silane compound. 12. The method of claim 11 wherein X, Y, and Z comprise at least one moiety selected from ester, thioester, ether, thioether, or combinations of such moieties. 13. The method of claim 1 wherein the surface treatment further comprises a non-polymerizable silane surface treatment compound. 14. The method of claim 1 wherein the inorganic oxide particles comprises silica, zirconia, or a mixture thereof. 15. The method of claim 1 wherein the inorganic oxide particles comprise nanoparticles. 16. The method of claim 1 wherein the inorganic oxide particles comprise nanoclusters. 17. The method of claim 1 wherein the surface treatment compound is combined with the inorganic oxide particles in a solvent. 18. The method of claim 1 further comprising drying the surface treated inorganic oxide particles to a free-flowing powder.
