Abstract
The effects of various surface modifications-specifically, sandblasting with aluminium oxide, sanding with 80-grit sandpaper and grooving with an inverted cone bur-on the tensile bond strength between universal tray adhesive and light-cure tray material utilising VPS impression material is of interest. Eighty specimens were fabricated with visible light polymerizing acrylic resin (Profibase) and divided into four groups (n = 20). Group A served as the control (no modification), while Groups B, C and D underwent sandblasting, sandpapering and bur grooving, respectively. The mean tensile bond strength among the groups had a significant difference, with Group C exhibiting the highest strength at 16.75 ± 1.83 MPa, followed by Group B at 9.30 ± 1.35 MPa, Group D at 8.33 ± 1.18 MPa and Group A at 5.60 ± 0.60 MPa, after a one-way ANOVA test was applied. Among the surface treatments, sandpapering with 80-grit sandpaper significantly enhanced the bond strength, while the control group showed the lowest adhesion.
