Effects of three bond agents on bond strength of titanium-ceramic system / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the effects of three bond agents on bond strength of titanium-ceramic system.Methods:The pure titanium specimens were randomly divided into three groups.Three different manufacturers' porcelains(Super Ti22,Duceratin,Titankeramik)were used specially for titanium-ceramic bonding.The specimens in each group were further divided into two subgroupsbond agent group and no bond agent group.Bond strength of specimens was measured by the three-point bending test according to ISO9693.The titanium-ceramic interfaces were investigated by SEM/EDS.Results:The bond strength of Super Ti22(35.84?2.17)MPa and Duceratin(35.45?2.37)MPa with bond agent group was significantly higher than that of no bond agent group(P0.05).The interfaces of Super Ti22 and Duceratin with bond agent groups were compact,while there were visible cracks and pores at the interface of other groups.Conclusion:The application of bond agent can improve bond strength of titanium-ceramic system.
