三种水门汀对IPS emax CAD陶瓷剪切强度的体外研究
Study of shear bond strength between IPS emax CAD ceramics and three luting cements in vitro
摘要
Abstract
Objective:To compare the shear bond strength(SBS)of three different cements adhesion to IPS emax CAD ceramic surface.Methods:Sixty IPS emax CAD disk specimens were prepared in 8 mm in diameter and 3.5 mm in thickness from disilicate ceramic blocks and divided into 3 groups(n=20).The specimens from all groups were bonded with three different cements using polyethylene tubes.The shear bond strength(SBS)was determined using a universal testing machine,and the specimens were also examined with a stereomicroscope.Results:The SBS values were 12.10±0.25 MPa,11.23±0.47 MPa and 3.73±0.46 MPa respectively.It was found that there was no significant differences between Multinlink N group and RelyTM U200 group(P>0.05).And the values of these two groups were higher than that of Fuji plus group,which was significantly different from the other two groups(P<0.05).Conclusion:Resin cement had the highest shear bond strength values when bonded to lithium disilicate ceramic surface.However resin-reinforced glass ionomer cement demonstrated significantly lower shear bond strength values.关键词
