A method of preparing a dental material comprising:
- creating a solvent-filler mixture by ultrasonically mixing at least one filler with a liquid monomer solvent, wherein the at least one filler comprises boron nitride, wherein the boron nitride comprises boron nitride in wurtzite form;
- and
- subsequently mixing the solvent-filler mixture with a powder resin to create a composite, wherein the ratio of resin to solvent-filler mixture is between about 2.0 gm of powder resin to about 1.0 ml of solvent-filler mixture and about 2.0 gm of powder resin to about 2.0 ml of solvent-filler mixture.
A method of preparing a dental material comprising:
- creating a solvent-filler mixture by ultrasonically mixing at least one filler with a liquid monomer solvent, wherein the at least one filler comprises boron nitride, wherein the boron nitride comprises boron nitride in amorphous form;
- and
- subsequently mixing the solvent-filler mixture with a powder resin to create a composite, wherein the ratio of resin to solvent-filler mixture is between about 2.0 gm of powder resin to about 1.0 ml of solvent-filler mixture and about 2.0 gm of powder resin to about 2.0 ml of solvent-filler mixture.
