“…However, the literature is controversial regarding the long‐term durability of the bond to zirconia blasted with silica‐coated alumina particles. Although the silica‐enriched surface has the potential to be bonded to silane‐containing materials, 57‐59 studies have shown that the formation of silica agglomerates weakly deposited to the zirconia surface may compromise the stability of the bonding 24,47,60 . In the present study, the presence of silica neither improved nor compromised the retention of crowns in comparison to alumina‐blasted samples, indicating the importance of rather increasing surface roughness than generating a silica‐silane mediated bonding.…”

Objective: To evaluate the effect of different surface treatments on the retention between zirconia crowns and tooth structure after in vitro aging. Materials and methods: Human third molars (n = 44) received crown preparations and CAD/CAM zirconia crowns were manufactured. Specimens were divided into two groups: no aging, control (NAC, n = 11) or aging (A, n = 33). NAC were bonded with universal adhesive (UA). Aged specimens were divided into three subgroups (n = 11) according to surface treatment: Control: no abrasion + UA; Alumina: alumina abrasion + UA; Silica: tribochemical silica coating + UA. The crowns were cemented with dual-cure resin cement. Specimens in group A were aged by a combination of mechanical, thermal, and pH cycling. Retention strength values were obtained by tensile tests and results were analyzed by one-way analysis of variance (ANOVA) and Tukey test (P < .05). Results: Aging decreased the retention strength in control specimens (P < .001). Surface treatment improved the retention strength of aged specimens (P < .001), with similar results between alumina and tribochemical silica coating. Conclusion: The chemical interaction between the universal bonding system and zirconia's surface was not sufficient to withstand artificial aging. Tribochemical silica coating did not promote additional retention in comparison to alumina blasting. Clinical significance: The long-term retention of translucent zirconia crowns to tooth structure using phosphate-based materials is improved by means of mechanical surface treatments such as alumina blasting and tribochemical silica coating.

“…The MDP is capable of establishing a very intensive and stable chemical interaction with hydroxyapatite [29]. Additionally, the MDP molecule has been shown to chemically bond with the outermost surface of zirconia [14,15,16,17,18,19]. The MDP molecule tends to remain with its adhesive group, the one containing the zirconia-oriented phosphate moiety, while its polymerizable group is oriented toward other resin monomers [15].…”

“…Even MDP that is present in universal adhesive bottles has an effect on improving the adhesion of resinous materials to zirconia ceramics when shear bond strength was evaluated [16,24]. The chemical treatment, either primer or adhesive application, affects the surface topography and its surface chemistry properties (roughness, wettability, and surface free energy of zirconia) [19]. The resins often used in adhesion procedures are challenged when long-term water storage artificially age the material by creating conditions for a slow water sorption and degradation of the structure of the resin materials [30,31].…”

“…Notably, the use of primers or resin cements containing 10-methacryloyloxy-decyl dihydrogen phosphate (MDP) may increase zirconia bond strength between zirconia ceramics and resin materials [13,14,15,16,17,18,19]. Furthermore, this approach represents a passive way of modifying the ceramic without blasting, abrasive burr application, or any other form of mechanical treatment.…”

The aim of this study was to evaluate the shear bond strength of orthodontic tubes adhered to ceramics with the Transbond™ XT bonding resin (3M, Maplewood, MN, USA) while varying the surface treatment. Then, the adhesive remaining index (ARI) was verified, and the representative fracture patterns were evaluated via scanning electron microscopy. Forty-eight zirconia blocks were divided into three groups, varying the number of layers of the 10-methacryloyloxy-decyl dihydrogen phosphate (MDP) primer: one, two, or three applications. In addition, 16 lithium disilicate IPS E.max ceramic disks (Ivoclar Vivadent, Schaan, Liechtenstein) were conditioned with 10% hydrofluoric acid for 20 s and underwent a single-layer primer application regimen. The four groups were further stratified to undergo bond testing after either 24 h (control) or 5000 cycles in a thermocycling machine. A shear bond strength test was performed (0.5 mm/min), and the MPa values obtained were submitted to a two-way analysis of variance and Tukey’s test. There was no statistical difference among the control group ceramics that received the varying surface treatments. After thermocycling, it was verified that both the E.max disks and the zirconia ceramics with three primer applications obtained the highest bond strength values. In the 24 h groups, a total displacement of the resin from the orthodontic tubes was observed (ARI of 1). After thermocycling, the highest prevalence of an ARI of 5 (adhesive failure) was observed among the zirconia ceramics with single-coat primer application, followed by those with triple-coat primer application (mixed failure). Three applications of the MDP-containing ceramic primer achieved the best result in the present study. Zirconia surface should be treated with three coats of MDP primer to achieve a level of bond strength similar to silica-rich phase ceramic.

“…Both systems pretreat the surface of the zirconia ceramic with a silane coupling agent that contains 3-methacryloxypropyletrimethoxysilan (3-MPTS) (Figure 1), and cohere the composite resin onto the surface with different bonding agents containing different adhesive monomers. The 10-methacryloyloxydecyl hydrogen phosphate (MDP) phosphate monomer with bonding agent is able to bond with the zirconia surface via a chemically stable covalent bond (-P-O-Zr-) 31 to enhance the bonding performance between the ceramic and resin cement or binder. However, some studies indicated lower bond strength was obtained between MDP-based resin cement and zirconia ceramic without sandblasting.…”

Zirconia is the preferred material for dental restorations; however, dental restorations are usually affected by zirconia fractures due to chipping and delamination of the veneer ceramic. One effective solution for repairing chemically inert zirconia frameworks is to strongly chemically bond them with the composite resin via surface modification. Thus, the bonding strength between the zirconia and composite resin determines the performance of dental restoration. Herein, we investigate the shear bond strength between zirconia ceramic and two ceramic repair systems before and after thermal cycling based on different surface pretreatments, including air-abrasion and a novel silane coupling agent. When treated with combined sandblasting, novel silane and 10-methacryloyloxydecyl hydrogen phosphate act as a bonding agent for the zirconia surface, and the maximum shear bond strength achieves 27.5 MPa, as measured by a universal testing machine through the average of 16 separate measurements. The results show that the combined treatment resists the interface damage caused by expansion and contraction during thermal cycling. The long-term bond durability is due to the micro-mechanical bond force formed by resin and ceramic, and the chemical bonds of Zr-O-Si at the interface. Results indicate that selective pretreating the surface results in high bond strength between the zirconia and the composite resin, which is meaningful to optimize dental restoration.
