Abstract
The effects of different brands' bond agents on the cpTi–porcelain bond strength was investigated in this study. The elemental composition and weight percentage of the three bond agents (Super Ti22, Duceratin Kiss, Titankeramik) for titanium were evaluated. The adhesion between titanium and porcelain with or without bond agent was measured by the three-point bending test. Then the cpTi–porcelain interfaces were characterized. All of the three bond agents were SiO2-based and mixed with different oxides. The bond strengths of Super Ti22 and Duceratin with bond agent were significantly higher than those without bond agent (p<0.05). There was no statistical difference when Titankeramik bond agent was used (p>0.05). The interfaces of Super Ti22 and Duceratin with bond agent were compact, while there were visible cracks and pores at the interfaces of the other groups. The results show that the bond agent can improve the cpTi–porcelain bond strength and may be suitable for clinical use.
