| 摘 要： | 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.

| 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 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 titani... |
