— Disks of four cobalt‐chromium alloys were electrolytically etched and bonded together using a microfilled restorative resin. The bonds of the resin to two of the tested alloys, Bondi‐loy and Vitallium, showed tensile strengths of approximately 18 MPa. The bonds were significantly stronger than those obtained using the other two alloys, Dentitan and Novarex. The tensile bond strengths etched Dentitan and Novarex were 5.3 and 7.5 MPa respectively. The etched and debonded surfaces were studied in SEM.
