“…Studies have observed the promising mechanical behavior of this material due to the polymer infiltration, which can dampen the stresses inside the material [28,29]. However, in terms of stain characterization durability against food bolus, there is some evidence of reduced wear resistance when compared to glass and polycrystalline ceramics [26,27]. The same pattern can be observed in the present results for the toothbrushing simulation.…”

“…The same pattern can be observed in the present results for the toothbrushing simulation. According to the literature, the surface roughness does not seem to be related to the staining durability; however, the bonding or union between ceramic and staining seems to be the determinant factor for staining longevity [27]. Therefore, the content of 58−63% of SiO2 in the hybrid ceramic is not enough to guarantee the strong adhesion with the methylmethacrylate stain layer, as occurs when a porcelain-fused staining layer is associated with the other ceramic materials.…”

“…It is important to emphasize the novelty of this material composition in comparison with the other evaluated glass ceramics and zirconia. The hybrid ceramic (58-63% of SiO2, 20-23% of Al2O3, 6-11% of Na2O, 4-6% of K2O, 0.5-2% of B2O3, <1% of CaO and <1% of TiO2) that contains a polymer infiltrated matrix has been developed to improve glass ceramics' (without reinforcement) mechanical properties, while maintaining the aesthetic properties [27]. Studies have observed the promising mechanical behavior of this material due to the polymer infiltration, which can dampen the stresses inside the material [28,29].…”

Aim: To investigate the effect of toothbrushing on different stained Computerd Aided Design/Computer Aided Manufacturing CAD/CAM ceramics. Materials and Methods: Fifty specimens (high translucency zirconia, YZHT; zirconia-reinforced lithium silicate, ZLS; feldspathic, FDL; hybrid ceramic, HC; all from Vita Zahnfabrik) were divided into five groups according to their staining technique. ZLS allowed the composition of two groups: ZLS1 with crystallization and staining together; ZLS2, with the stain firing after the crystallization. YZHT received a stain firing after the sintering process, and FDL received stain firing directly. The HC was stained with acrylic staining, and was light-cured on its surface. The specimens were brushed in total for 150,000 cycles at 2.45 N with 180 strokes/min. Surface measurements to obtain Rz were performed after 50,000, 100,000 and 150,000 cycles, with five evaluation lines (5 mm) per specimen orthogonal to the brushing direction, covering brushed and unbrushed areas. The wear was analyzed using two-way ANOVA and Tukey tests (α = 5%). Scanning electron microscopy (SEM) was performed to access the surface profile. The wear was affected by material (p < 0.001) and time (p = 0.139). Superior wear (µm) was observed for HC (6.6 ± 4.4; 6.8 ± 4.0; 9.2 ± 3.5) compared to ZLS2 (1.0 ± 0.3; 1.2 ± 2.2; 1.3 ± 0.3), YZHT (1.0 ± 0.1; 1.2 ± 0.3; 1.2 ± 0.3), ZLS1 (0.9 ± 0.1; 1.1 ± 0.5; 1.2 ± 0.3) and FDL (0.9 ± 0.1; 0.9 ± 0.1; 1.0 ± 0.2) after 5, 10 and 15 years of simulation, respectively. SEM showed different wear patters for HC with the removal of the glaze layer. HC showed a higher staining wear rate compared to the glass-based and polycrystalline ceramics after 15 years. The extrinsic characterization of feldspathic ceramic showed its superior longevity compared to the evaluated high-translucency zirconia, zirconia-reinforced lithium silicate, and hybrid ceramic.

“…Glazing, accompanied by staining of ceramics is a common step in dental laboratories to achieve the final shade and finish of ceramic restorations. The aim is to seal the open pores on the surface of sintered porcelain and to produce a smooth glossy layer [21]. Despite there being several reports that glazing monolithic zirconia wears off the surfaces in contact with antagonists [22][23][24], the practice of staining and glazing monolithic restorations are commonly employed to achieve an improved and acceptable aesthetics that is superior to that of the monolithic intrinsic colour of the crown [21,25,26].…”

(1) Background: The effect of glazing on the mechanical properties of monolithic high translucent zirconia is not well reported. Therefore, the purpose of this study was to evaluate the effect of glazing on the flexural strength of high translucent zirconia; (2) Methods: Ninety specimens were prepared from second-generation 3Y-TZP high translucent blocks and divided into three groups. Glaze materials were applied on one surface of the specimen and subjected to a four-point bending test and flexural stress and flexural displacement values were derived. Descriptive fractographic analysis of surfaces was conducted to observe the point of failure and fracture pattern.; (3) Results: Control-nonglazed (647.17, 1σ = 74.71 MPa) presented higher flexural strength values compared to glaze I (541.20, 1σ = 82.91 MPa) and glaze II (581.10, 1σ = 59.41 MPa). Characteristic strength (σƟ) from Weibull analysis also observed higher (660.67 MPa) values for the control specimens. Confocal microscopy revealed that glazed surfaces were much rougher than control surfaces. Descriptive fractographic analysis revealed that there was no correlation between the point of failure initiation and flexural strength; (4) Conclusions: The test results demonstrated that glazing significantly decreased the flexural strength and flexural displacement of the zirconia specimens.
