Resumé

The aim of this study was to test different types and aggregation of nanoparticles to lithium disilicate. Sixty samples were divided into six groups of 10 samples as following: Group 1 (control) lithium disilicate outside adding of nanoparticles Group 2 lithium disilicate accompanying adding of titanium dioxide nanoparticles, Group 3 lithium disilicate accompanying adding of silica dioxide nanoparticles, Group 4 lithium disilicate accompanying adding integrate of 2.5% titanium dioxide and 2.5% with silica dioxide nanoparticle Group 5 lithium disilicate accompanying adding connect of 3% titanium dioxide and 3% silica dioxide nanoparticle, and Group 6 lithium disilicate accompanying addition integrate of 5% titanium dioxide and 5% silica dioxide nanoparticle. All samples were thermocycled for 2000 cycles, before evaluations. Shear bond strength (SBS) test results revealed a meaningful increase in changed lithium disilicate on zirconia cores (group 2, 3, 4, 5 and 6) in comparison to the control group. Mixtures adding 3% titanium dioxide and 3% silica dioxide (group 5) to lithium disilicate displayed maximal bond substance than the other groups. No dissimilarities in the effect of titanium dioxide nano-atoms added (group 2) and silica dioxide nano-atoms addition (group 3), and between group 4 and 6 were found. Lithium disilicate and zirconia gist maybe revised by adding of either 5% wt/wt of titanium dioxide nanoparticles or 5% wt/wt of silica dioxide nanoparticles to lithium disilicate.
