Patent ID: 8710115

Claim:
A method for producing a dental composition comprising the steps of (i) providing the following components: (a) about 3 to about 80 parts by weight of an ethylenically unsaturated acidic compound, (b) about 5 to about 40 parts by weight water, (c) about 1 to 10 parts by weight of a functionalized silane compound, (d) about 0.5 to about 10 parts by weight of an initiator, (e) from about 2 to about 20 wt % of a non-surface treated filler, and not more than about 20 wt % of other fillers (f) about 5 to about 40 parts by weight of a solvent other than water, and (g) about 0 to about 80 parts by weight, of a second ethylenically unsaturated compound being different from component (a); (ii) mixing the components of step (i) in a manner such that the functionalized silane compound reacts with the non-surface treated filler in-situ in the presence of the ethylenically unsaturated acidic compound to form an acidic dental composition; and (iii) applying the acidic dental composition to a surface of a tooth.
