Abstract
A dental filler and dental resin restorative composition containing the dental filler is provided. The dental filler is prepared by pre-treating an acid-reactive filler with a polymerizable monomer or oligomer pre-treatment chemical having at least one acid or acid-precursor functional group, at least one polymerizable unsaturated carbon-carbon bond, and a molecular weight of about 1,000 grams per mole or less.
Claims22
A pre-treated dental filler comprising a reaction product of an acid-reactive filler and a pre-treatment chemical, wherein the pre-treatment chemical is a polymerizable monomer or oligomer comprising:

- and
- a molecular weight of about 1,000 grams per mole or less.
A dental restorative composition comprising:
- (A) a polymerizable resin;
- (B) a pre-treated dental filler comprising a reaction product of an acid-reactive filler and a pre-treatment chemical, wherein the pre-treatment chemical is a polymerizable monomer or oligomer comprising
- at least one acid or acid-precursor functional group,
- at least one polymerizable unsaturated carbon-carbon bond, and
- a molecular weight of about 1,000 grams per mole or less;
- and
- (C) a polymerization initiator.
A method of malting a polymerizable dental restorative composition comprising:
- forming a pre-treated dental filler comprising a reaction product of an acid-reactive filler and a pre-treatment chemical, wherein the pre-treatment chemical is a polymerizable monomer or oligomer comprising
- at least one acid or acid-precursor functional group,
- at least one polymerizable unsaturated carbon-carbon bond, and
- a molecular weight of about 1,000 grams per mole or less;
