Abstract

The aim of this study was to investigate a suitable bonding test to evaluate the bonding characteristics of resin-based luting cements as dental luting material to cp titanium. Five adhesive resin-based luting cements were bonded to polished or blasted titanium surfaces with a cylindrical titanium specimen. Tensile and shear bond tests were performed to determine tensile and shear bond strengths (TBS and SBS, respectively), and the rate of remnant cement (RRC) was also calculated by image analysis of the fractured surface. SBS was significantly higher than TBS (p<0.05). The relationship between SBS and TBS showed a linear regression at a coefficient of determination (R²) of 0.82; however, that for the blasted surface was not clear. The relationship between RRC and SBS or TBS showed an exponent regression curve; especially, TBS was related to RRC with a highly significant coefficient (R²=0.99). Tensile bonding tests using polished titanium specimens seem to be preferable to evaluate the bonding characteristics, since they could measure not only the bond strength but also the RRC easily.
