Abstract:
1. A three part dental bonding system, comprising: (a) an etch solution comprising an inorganic acid, present in an amount of from about 1 to about 10 parts by weight; an organic acid, present in amount from about 0.1 to about 10 parts by weight; a solvent present in an amount from 0 to about 65 parts by weight; an ethylenically unsaturated functional monomer, present in an amount from about 0.1 to about 10 parts by weight and water, present in an amount from 0 to about 50 parts by weight, all components in an amount to equal a total of 100 parts by weight; (b) a preparative solution comprising an ethylenically unsaturated functional monomer, present in an amount of from about 5 to about 25 parts by weight; a polyethylenically unsaturated functional crosslinking monomer, present in an amount of from about 10 to about 40 parts by weight; a solvent present in an amount from 0 to about 65 parts by weight; and water, present in an amount from 0 to about 50 parts by weight, all components in an amount to equal a total of 100 parts by weight; and (c) a curable composite comprising an ethylenically unsaturated functional monomer, present in an amount of from about 10 to about 30 parts by weight; a polyethylenically unsaturated functional crosslinking monomer, present in an amount of from about 50 to about 90 parts by weight; a solvent present in an amount from 0 to about 15 parts by weight; and water, present in an amount from 0 to about 15 parts by weight, all components in an amount to equal a total of 100 parts by weight.
