Abstract
Objective:To investigate the effect of gold sputter coating on the adhesion between titanium alloy and porcelain with different time. Methods:Sixty-four titanium alloy specimens( d=10 mm,h=0. 5 mm) were cut from a cylin-drical titanium alloy bar and divided randomly into 8 groups(n=8). The control group,denoted as SB,would only be treated with sandblasting. According to the different coating time(s),the groups treated with gold sputter coating were denoted as Au500,Au600,Au700,Au800,Au900,Au1000,Au1100. Specific dental porcelain(Super porcelain Ti-22)was fused onto the titanium alloy surfaces. After the shear bond strength tests were performed, the results were statistically analysed. Stereo-microscope was used to characterize the titanium-porcelain interfaces and determine the mode of failure. Results:The shear bond strength of Au800(19. 37 ± 0. 74 MPa)and Au900(17. 67 ± 1. 43 MPa)was higher than SB(15. 04 ± 0. 87 MPa)(P<0. 05). Stereomicroscope illustrated that the fracture mode of all groups was mixed failure. Conclusion:Under the conditions of this study,the gold sputter coating can significantly improve the shear bond strength between Super porcelain Ti-22 and ti-tanium alloy and the 800 s was the optimal coating time.关键词
