Abstract

Titanium can adhere to high polymer material through the oxidation coating. Therefore, it is expected that titanium will be applied to resin facing crown by the non-retention method. A suitable treatment of the titanium surface was investigated to obtain strong adhesion between titanium and resin. It was clarified that resin adhered firmly to the titanium surface treated with Al<SUB>2</SUB>O<SUB>3</SUB> sandblasting for 45 sec/cm<SUP>2</SUP> and heating at 600°C for 60 min, and then the bond strength was shown for a long time. In this study, the influences of the heating time on the adhesive strength was investigated. Test specimens using three kinds of facing resins (Cesead II, Thermoresin LC II, and Solidex) were prepared, and the shear bond strength of resin to the treated titanium surface after thermal cycling was examined. In addition, the interface of titanium and resin was examined under the scanning electron microscope. The results were as follows:<BR>Cesead II showed durable adhesive strength to the titanium surface treated with Al<SUB>2</SUB>O<SUB>3</SUB> sandblasting for 45 sec/cm<SUP>2</SUP> and heating at 600°C for 45 min, and cohesive failure of opaque resin was observed on the titanium surface fractured after 20, 000 thermal cycles in the bond strength test.
