“…Alternative methods for conditioning the surface of Y-TZP crowns prior luting have been suggested in the literature, such as aluminum oxide sandblasting and tribochemical silica coating [2,7]. The latter has been regarded as the preferred method for zirconia surface treatment, based on the bond strength literature [7][8][9][10].…”

“…Alternative methods for conditioning the surface of Y-TZP crowns prior luting have been suggested in the literature, such as aluminum oxide sandblasting and tribochemical silica coating [2,7]. The latter has been regarded as the preferred method for zirconia surface treatment, based on the bond strength literature [7][8][9][10]. However, there is also scientific evidence indicating that sandblasting creates critical defects on the ceramic surface which might become crack initiators and compromise the longterm performance of the zirconia restoration [11,12].…”

Objective: This study investigated the influence of different surface treatments on zirconia surface energy, roughness and microshear bond strength. Material and Methods: Forty eight slices of Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP- VITA In-Ceram® YZ for inLab®) (6.4 x 3.2 x 1.6 mm) were divided into 3 groups according to the surface treatment (n = 16): YTZP_control -untreated; YTZP_plasma -surface treatment with non-thermal oxygen plasma; YTZP_primer - coating with ceramic primer. Surface energy (n = 6) was measured with a goniometer; and surface roughness (n = 10) was analyzed with a 3D profilometer were performed over zirconia surface. On the same specimens of surface roughness, on the treated zirconia's surface, resin cement (PANAVIA V5 - Kuraray Noritake Dental) was built up by inserting the resin cement into Tygon tubes (1 mm of internal diameter X 1 mm length). After 24 h storage, microshear test was assessed. Data were analyzed by one-way ANOVA and Tukey post-hoc test (p < 0.05). Results: Non-thermal oxygen plasma treated specimens exhibited higher statistically significant surface energy (p = 0.00) and bond strength (p = 0.00) when compared to control and primer groups. Roughness test (p = 0.897) could not detect statistical difference among the tested groups. Conclusion: Non-thermal oxygen plasma should be a suitable alternative for zirconia surface treatment prior to luting hence it improved microshear bond strength and provided higher surface energy without affecting surface roughness. Keywords Adhesion; Non-thermal plasma; Surface treatment.

“…[14][15][16] The most popular clinical surface conditioning techniques to improve the resin-zirconia interface are sandblasting, [17][18][19] silica coating, [20][21][22] carbon dioxide (CO 2 ) laser irradiation, and Erbium-Doped Yttrium Aluminum Garnet (Er:YAG). 23,24 Nevertheless, there is still no ideal zirconia surface conditioning method able to provide sufficient effectiveness of adhesion on zirconia surfaces.…”

“…22 It is even suggested that micromechanical retention, which increases with the increase in surface roughness, may be the most effective mechanism for the adhesion of oxide ceramics. 23 Several studies evaluated different pulse energies, but the current study shows that pulse length should be taken into consideration as well. The ceramics in the market have differences in composition and microstructure, and these variations might affect the results of laser application on the surface properties of the material.…”
