Effects of 10-MDP Based Primer on Shear Bond Strength between Zirconia and New Experimental Resin Cement

Abstract

To date, numerous materials in the dental field are marketed to ensure stable adhesive cementation of zirconia ceramics (Y-TZP). The aims of this study were to assess the shear bond strength of the new experimental cement Surgi Dual Flo’ Zr to Y-TZP compared to Panavia V5 cement, and to evaluate the effect of 10-MDP (10-methacryloyloxydecyl dihydrogen phosphate) containing primer on their bond strength. Twenty composite cylinders and Y-TZP disks were adhesively luted and divided into four groups based on cement type used and application or not of 10-MDP. The groups (n = 5 each) were S 10MDP (Surgi Dual Flo’ Zr with 10-MDP); S no 10MDP (Surgi Dual Flo’ Zr without 10-MDP); P 10MDP (Panavia V5 with 10-MDP); P no 10MDP (Panavia V5 without 10-MDP). Maximum load resistance (ML) and shear bond strength (SBS) were tested and mode of failure qualitative documented via scanning electron microscopy. The data were analyzed with one-way ANOVA, Holm-Sidak method, and Bayesian analysis. ML and SBS were significantly higher in S 10MDP than in S no 10MDP; and in P 10MDP than in P no 10MDP (p < 0.05). No significant differences were found between S 10MDP and P 10MDP; S no 10MDP and P no 10MDP (p > 0.05). Cohesive, adhesive, and mixed failure occurred among the groups. Bond strength between the experimental resin-based cement and Y-TZP was adequate for clinical application when 10-MDP was added. 10-MDP containing primer was effective improving the bond strength to Y-TZP more than the different type of resinous cement.

Fracture Resistance of Zirconia-Reinforced Lithium Silicate Ceramic Crowns Cemented with Conventional or Adhesive Systems: An In Vitro Study

“…Considering the fragility and the limited flexural strength of glass ceramics, the use of cements based on composite resin indeed allows an increase in the fracture resistance of the restoration and improvement in its duration. In fact, comparing the resin-based cements with the traditional cements (such as the polycarboxylate cements of Zn, Zn phosphate or GIC), the former has higher values of compression strength and, as a result, they ensure a better support to ceramic restorations [27,28].…”

“…On the other hand, due to its polycrystalline chemical structure, zirconia cannot be subject to common surface acidification methods with the use of hydrofluoric acid; therefore, the cementation necessarily has to rely on mechanical/chemical surface treatments, possibly followed by application of silane [27].…”

Influence of Non-Thermal Atmospheric Pressure Plasma Treatment on Retentive Strength between Zirconia Crown and Titanium Implant Abutment

“…Based on the previous study, the rate of technical complications was 2–9% for veneer fractures, 3–8% for abutment/screw loosening, and 5% for retention loss over the approximately five-year follow-up period [ 6 ]. In particular, when bonding zirconia with resin cement, conventional ceramic bonding techniques provide insufficient bond strength [ 7 ]. For feldspathic ceramic, the bonding strength with resin cement increases through micromechanical retention with hydrofluoric acid and chemical bonding using a silane agent [ 8 , 9 ].…”

Effect of different surface treatment modalities on crystal structure and biaxial flexural strength of super translucent zirconia.

“…10 Chemical surface pre-treatment of zirconia with MDP-containing primer resulted in a durable bond between resin and translucent zirconia. 11,12 The adhesive functional monomers are believed to make hydrogen bonds with the metal oxides at the interface of zirconia / resin, resulting in improved wettability. 13 Since results are not usually notable, the combination of primers especially those containing MDP and airborne particle abrasion is liable to form good bond strength, particularly in long term.…”
