Effect of different surface treatments on the bond strength of zirconia to resin cement. An in vitro study

Zircos-E etching, APA+Zircos-E and Biomic LiSi Connect exhibited significantly higher bond strength than the control, with Biomic LiSi Connect demonstrating the highest mean SBS (<i>p</i> < 0.001). Failure mode analysis showed no statistically significant differences among groups. Both Zircos-E and Biomic LiSi Connect significantly enhanced the bond strength.
