Abstract

CP titanium specimens treated by alumina sandblasting, HF/HNO3 chemical polishing, and electric discharge machining in kerosine oil were prepared and the adhesion to two composite resins for veneering which had different adhesing systems was evaluated by the compressive shear test.Adhesion of titanium treated by sandblasting to composite resins was equivalent to that of Co-Cr alloys and the clinical application of titanium to composite resin veneered crownbridges was thought to be promising.Surface treatment of titanium was found to affect the adhesion of titanium to composite resins and titanium treated by chemical polishing and electric discharge machining showed lower adhesion.
