Abstract
The effect of primers containing copper salts on adhesion between enamel and stainless steel was studied in a trial to improve durability of TBB type resin cements. Bovine enamel surfaces were treated with 10% phosphoric acid, then with acetone primers containing copper salts, and finally bonded with TBB resins. Tensile strengths of the bonded specimens were measured after thermocycling testing in water and compared with those obtained for commercial composite type resin cements. A combination of a primer containing copper (II) methacryloyloxyethyl succinate and 4-META/MMA-TBB resin was most effective in improving the durability, and superior to the commercial resin cements. The mean and lowest bond strength values of 21 MPa and about 12 MPa, respectively, were retained after 2,000 thermocycles.
