“…Due to the absence of any glassy matrix, zirconia is free from silica and, consequently, cannot be conditioned with conventional acid etching techniques, differently from glass-ceramics [119,122]. Several surface treatments aimed at getting a reliable bond to the substrate have been reported in the literature but to date this topic is still controversial [154][155][156][157][158][159][160][161][162][163]. Aggressive sandblasting (i.e.…”

Background: The introduction of the new generation of particle-filled and high strength ceramics, hybrid composites and technopolymers in the last decade has offered an extensive palette of dental materials broadening the clinical indications in fixed prosthodontics, in the light of minimally invasive dentistry dictates. Moreover, last years have seen a dramatic increase in the patients' demand for non-metallic materials, sometimes induced by metal-phobia or alleged allergies. Therefore, the attention of scientific research has been progressively focusing on such materials, particularly on lithium disilicate and zirconia, in order to shed light on properties, indications and limitations of the new protagonists of the prosthetic scene. Methods: This article is aimed at providing a narrative review regarding the state-of-the-art in the field of these popular ceramic materials, as to their physical-chemical, mechanical and optical properties, as well as to the proper dental applications, by means of scientific literature analysis and with reference to the authors' clinical experience. Results: A huge amount of data, sometimes conflicting, is available today. Both in vitro and in vivo studies pointed out the outstanding peculiarities of lithium disilicate and zirconia: unparalleled optical and esthetic properties, together with high biocompatibility, high mechanical resistance, reduced thickness and favorable wear behavior have been increasingly orientating the clinicians' choice toward such ceramics. Conclusions: The noticeable properties and versatility make lithium disilicate and zirconia materials of choice for modern prosthetic dentistry, requiring high esthetic and mechanical performances combined with a minimal invasive approach, so that the utilization of such metal-free ceramics has become more and more widespread over time.

“…Different bonding mechanisms may occur due to the variation of chemical components. In addition, a variety of surface treatments such as chemical and/or electrical etching (Krueger et al, 1990), airborne particle abrasion (Okada et al, 2019), used metal primer and silica coating (Dal Piva et al, 2019) have been documented (Hattar et al, 2014) and are supposedly used to enhance the bond strength of the restoration to the cement. Sandblasting the metallic alloys with aluminum oxide is commonly employed for surface cleaning and a proper retentive topography, with a consequent increase in the adhesive bond (Fonseca et al, 2012).…”

The aim of this in vitro study was to compare the shear bond strength (SBS) of three different resin cements to different computer-aided design/computer-aided manufacturing (CAD/CAM) framework materials (cobalt-chromium, titanium, and zirconia). Specimens (12 x 2 mm) were divided into three different main groups according to materials (n=10); Cr-Co discs (Hard metal; HM), titanium discs (T), and zirconia discs (Z) and embedded in acrylic resin, and smoothed with silicon carbide papers and sandblasting with 50 μm aluminum oxide. Specimens of each framework materials were divided into three subgroups; (1) Universal resin cement, (2) Syringeable resin ionomer cement, and (3) Self-adeziv resin cement. The shear bond strength test was conducted using a universal testing machine. Data (MPa) was analyzed using one way ANOVA, Kruskal Wallis tests, and post-hoc tests. There was no statistically significant difference between SBS value of universal resin cement and self-adhesive cement for each material (P > 0.05). Resin ionomer cement showed the lowest SBS value (P < 0.05). No significant differences in SBS were found between framework materials. The SBS values of self-adhesive cements are as high as universal resin cements for hard metal, titanium and zirconium supported restorations.

“…Depending on the distance and air pressure of the sandblasting, as well of the particle size of the abrasive, the blasted surface will be modified differently. Another way is silica-coating, blasting the surface with silica-coated alumina particles which gives an etchable inner surface of the restoration [20]. The term luting agent in this study is interchangeable with the term cement [21].…”

Aim:The aim of the present study was to evaluate the shear bond strength of zirconia, stabilised with 5% yttria, luted to enamel and to evaluate the fracture pattern at loss of retention. Methods: A total of 53 test specimen were manufactured from two partially stabilised zirconia materials, Zirkonzahn Prettau Anterior (ZPA) (n ¼ 16) and Whitepeaks CopraSmile Symphony 5 layer (WCS) (n ¼ 18), and a lithium disilicate (Ivoclar e.Max Press) (n ¼ 19) acting as control. All test specimens were cemented to human enamel with Variolink Esthetic DC and then subjected to a shear bond strength test. Fracture and surface analysis were performed using light and scanning electron microscope. Results: No significant differences in shear bond strength were detected when analysing the three groups. Dividing them according to the fracture pattern significant difference in shear bond strength between the two zirconia groups could be seen analysing test bodies with failure of adhesion to the test body, but not to enamel. The ZPA had higher shear bond strength (23.68 MPa) than WCS (13.00 MPa). No significant differences were seen compared to the control group (19.02 MPa).Conclusion: Partially stabilised zirconia shows potential as a material to be used where macro mechanical bonding is not possible, although this study does not reveal how or if the bonding deteriorates over time.
