The study evaluated the effect of different titanium surface treatments on the shear bond strength (SBS) between titanium and zirconia bonded with resin cement. Fifty titanium disks were embedded in acrylic blocks. Titanium specimens without surface treatment were used as controls. Surface treatment methods such as etching with 37% phosphoric acid for 15 min, etching with 9% hydrofluoric acid for 15 s, treating with 50% hydrogen peroxide for 15 min, and sandblasting for 20 s with 50 µm alumina particles were assessed. Fifty zirconia disks (surface treated through sandblasting and applied with ceramic primer) were bonded with resin cement onto the titanium treated surfaces (5 groups; n = 10/group). All specimens were stored in water at 37 °C for 24 h. After 5000 cycles of thermal cycling, SBS test was performed. One-way ANOVA and Tukey HSD tests were used for statistical analysis. The titanium samples that were sandblasted or treated with 50% hydrogen peroxide exhibited significantly higher shear bond strength compared to the rest of the specimens. Treating a titanium surface with sandblasting or 50% hydrogen peroxide increases its SBS with zirconia. Surface treatment with 50% hydrogen peroxide is simple, low cost, and does not require specialized equipment. [ABSTRACT FROM AUTHOR] |
