“…[18] The above consideration might be supported by the observation of wide zones of exposed/uncoated zirconia grains when analyzing [Roc_S] surfaces at SEM (comparison between Figure 1(d) and (e)). In our study, the Rocatec pretreatments provided bond strength values comparable to the alumina sandblasting conditioning; this result is in agreement with that of Sciasci et al [39], which also found statistically similar values for the groups air abraded with 50 μm Al 2 O 3 (10.8 ± 2.4 MPa), 120 μm Al 2 O 3, (10.8 ± 1.8), Rocatec™ Soft (10.1 ± 2.5) or Rocatec™ Plus (11.2 ± 2.1) when using Panavia F (Kuraray Medical Inc.) and a standardized air pressure (0.28 MPa).…”

The aim of this investigation was to assess the influence of several surface treatments on the shear bond strength (SBS) of a self-adhesive resin cement containing 10-methacryloxydecyl-dihydrogenphosphate monomer to densely sintered zirconia ceramic, before and after thermal cycles. Hundred densely sintered zirconia cylinders were divided into five groups (n = 20). Each of them received a different surface treatment: (1) control [No_T], with the zirconia surface unconditioned, (2) low pressure air abrasion [Sand_S], (50 μm, 1 bar), (3) standardized air abrasion [Sand_H], (50 μm, 2.8 bar), (4) standardized Rocatec™ Plus (silica-coated alumina oxide) air abrasion (2.8 bar) and silanization [Roc_H], (5) low pressure Rocatec™ Plus (silica-coated alumina oxide) air abrasion (1 bar) and silanization [Roc_S]. Five more surface-treated specimens were addressed to scanning electron microscope for qualitative observations. After specimen fabrication, subgroups of 10 bonded samples were stored in water either for 24 h (T1) or subjected to 5000 thermal cycles (T2); SBSs were determined with a universal testing machine at a crosshead speed of 1 mm/min. At T1, mean SBSs (MPa) obtained for the examined groups were: [Sand_H] 16.24 ± 2.95; [Sand_S] 16.01 ± 2.68; [Roc_H] 17.17 ± 1.64; [Roc_S] 15.92 ± 1.99. All surface treatments positively affected (p < 0.05) the initial selfadhesive cement adhesion to zirconia with respect to No_T (13.29 MPa). Artificial aging decreased the bond strength in all test groups significantly, but no spontaneous debonding was observed in [No_T]: at T2, SBS values ranged from 7.76 ± 2.37 (No_T) to 8.89 ± 1.74 (Sand_S), with no statistically significant difference between groups (p = 0.5293). Both air abrasion with alumina oxide and Rocatec™ universal bonding system, used with hard or low air pressure, produced comparable effects on cement-zirconia interface before and after thermal cycles. After artificial aging, minimal differences in bond strength values between sandblasted and control groups were not of statistical significance.

“…23,24 Therefore, innovative adhesive strategies combining surface treatment with chemical bonding have been developed. 12,14,[25][26][27][28][29][30][31][32][33] Silane coupling agents can reduce the surface tension of a substrate, resulting in a higher surface energy that is more suitable for bonding. 34 Thus, the hydrophobic luting resin can adhere to hydrophilic surfaces, such as silica, glass, or glass ceramics.…”

“…With these parameters, the particle factor had significant effect on the adhesion. According to the results of a recent study, particle size did not influence the adhesion when aluminum oxide or silica coated aluminum oxide particles [27]. Nonetheless, in that study, bonded specimens were not aged through long-term water storage.…”
