Abstract:
Objective This study was made to observe the effect of different surface treatment pure titanium on bond strengt of pure titanium and porcelain, and find the mechanism as basisi of clinic use.Methods Dental pure titanium(TA2) was choosen as material,before applied for porcelain the rest groups were treat as followings:the metal substrate surface was smeared with Nano-scale material(nano-SiO2,nano-gold and nano-palladium particles), compared with control group ,and find the change of bond strengt. The change of bond strengt in the Ti-porcelain interface area were observed with scanning electron microscopy (SEM) and electron probe microanalysis(EPMA) respectively.Results Before applied for porcelain, the metal substrate surface was smeared with nano-SiO2 and nano-gold particles,we acquired a positive effect to increase the bonding strength,while using nano-palladium particles has a negativee ffect. Conclusion The bonding strength was enhanced when the metal substrate surface was smeared with nano-SiO2 before applied for porcelain,so we adviced that it should be used in practice as a try.
