In this study, we investigated whether the silane and alkali treatments improve the chemical bonding between twochromium-chromium alloys and acrylic resin and thus the shear bond strength. A silane solution was prepared using 3-MPTMS.
The alloy specimens were treated with silane and alkali, prepared as four experimental groups: untreated (UT), silane treated(ST), alkali treated (AT), and alkali/silane treated (AST) groups. In addition, the contact angles and surface roughness ofthe alloy surfaces of the four groups were measured. The acrylic resin was bonded to the alloy specimens, and then theresin was polymerized to form a bonded specimen. After measuring the shear bond strength, the failure modes were examinedusing scanning electron microscopy. Results for all groups were analyzed using two-way ANOVA followed by Tukey's multiplecomparison test at a significance level of 0.05. The statistical analysis showed no significant differences in Ra value for allgroups (p>0.05). In both alloys, the ST and AST groups showed relatveily higher shear bond strengths (p<0.05) than theUT and AT groups. The UT and AT groups showed complete adhesive failure at the fractured surfaces. In this study, thesilane treatment was shown to be effective to improve the shear bond strength, but the alkali treatment did not show anysignificant effect.
