“…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.

“…(21,29,31,32,38) Foi assim que muitas estratégias foram desenvolvidas para alterar a superfície da zircônia provocando rugosidade, o que aumenta a superfície de ligação. (3,9,29,34,36,37) Os testes que medem a força de adesão são muito importantes na realização de pesquisas em Odontologia, pois eles permitem determinar a eficácia de uma técnica adesiva para, posteriormente, serem avaliados por meio de ensaios clínicos controlados. (28,38,62) Os testes de microcisalhamento são recomendados para este fim porque têm a vantagem de serem facilmente aplicados nas cerâmicas cristalinas.…”

“…Os melhores resultados do presente estudo in vitro foram encontrados quando o primer e o cimento contendo MDP foram usados em conjunto com o tratamento triboquímico(26,21MPa), mas os valores diminuíram após a termociclagem(11,9MPa). Não obstante, ambos os resultados foram maiores que os respectivos pares dos demais grupos, incluindo o grupo controle, o que sugere uma influência positiva do tratamento de superfície do grupo Rocatec.Com o propósito de aumentar a rugosidade da superfície cerâmica e expandir a área de adesão para melhorar a retenção micromecânica,(23,32,43) diversos estudos avaliaram o efeito do condicionamento das superfícies de Y-TZP com distintos tipos de laser (9,23,29,43,55,60). Fatores como comprimento de onda, parâmetros de irradiação, posição focal, velocidade de avanço sobre a superfície irradiada, taxa de repetição de pulso, largura de pulso e composição do material Por outro lado, outros autores relataram uma influência aceitável do laser de Er,Cr:YSGG com potências entre 0,5 e 5W em cerâmica cristalina de alumina (56).…”

The aim of this study was to evaluate the effect of different output powers of Er,Cr:YSGG laser and the association with tribochemical silica coating on the bond strength between zirconia ceramic and two resin cements. One hundred ninety-two zirconia ceramic bars (IPS e-max ZirCAD Ivoclar Vivadent-) were sectioned (6 × 6 × 4 mm), sintered, and randomly divided into 12 groups for each cement system according to the surface treatment (n = 8): C-without treatment (control); R-tribochemical coating + resin cement (control); 2L-laser (2.0 W) + resin cement; 2LR-laser (2.0 W) + tribochemical coating + resin cement; R2L-tribochemical coating + laser (2.0 W) + resin cement; 2.5L-laser (2.5 W) + resin cement; 2.5LR-laser (2.5 W) + tribochemical coating + resin cement; R2.5L-tribochemical coating + laser (2.5 W) + resin cement; 3L-laser (3.0 W) + resin cement; 3LR-laser (3.0 W) + tribochemical coating + resin cement, R3L-tribochemical coating + laser (3.0 W) + resin cement; and RPHO-tribochemical + resin cement + photoactivation (control). After the surface treatment, the respective primers were applied, and resin cements, Multilink N, Ivoclar Vivadent (M), and Panavia F 2.0, Kuraray Medical Inc. (P), were inserted into Tygon molds which were bonded to the zirconia bars. Each specimen received two cements bars. After 24 h of storage in a relative humidity (100%) at 37 °C, they were evaluated by the microshear test speed of 1 mm/min. The microshear values were analyzed by one-way ANOVA and Tukey's test (α = 0.05). ANOVA showed statistically significant differences among the evaluated groups. The highest bond strength was observed in RPHO, which statistically differed from all groups. The lowest bond strength was observed in M2.5L (Multilink N) and in P3LR (Panavia F 2.0). It can be concluded that the lowest power output tested was suitable and showed bond strength values similar to tribochemical silica deposition. The light curing is important to adhesion and the tribosilicatizated surface achieves similar microshear values to untreated surface in absence of light.
