目的:观察3 种粘接瓷对钛瓷结合强度的影响,分析粘接瓷作用机制.方法:将纯钛试件随机分为3 组分别采用纯钛专用瓷Super Ti22,Duceratin,Titankeramik进行烧结,每种瓷粉又分为涂布粘接瓷组和未涂布粘接瓷组,共6 组.根据ISO9693标准,运用三点弯曲方法测试各组钛瓷结合强度.对钛瓷结合界面进行扫描电镜观察和能谱分析.结果:Super Ti22涂布粘接瓷组结合强度为(35.84±2.17) MPa,Duceratin涂布粘接瓷组结合强度为(35.45±2.37) MPa,均显著大于各自未涂布组(P<0.05);Titankeramik涂布粘接瓷组结合强度为(31.73±1.66) MPa, 略大于其未涂布组(29.86±2.48) MPa,但差异无显著性(P>0.05).电镜观察Super Ti22和Duceratin涂布粘接瓷组钛瓷结合界面结合紧密,未见明显孔隙出现;其余各组均可见明显孔隙.结论:粘接瓷的应用有利于钛瓷结合强度的提高.

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 subgroups:bond 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(P<0.05). Titankeramik with bond agent group showed a little higher bond strength than without bond agent, but no significant difference in statistics(P>0.05). 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.
