Effect of Different Surface Treatment Methods on the Shear Bond Strength of Resin Composite/Zirconia for Intra-oral Repair of Zirconia Restorations

Abstract

Objective A durable resin/zirconia bond is essential for successful intra-oral repair of zirconia restorations. The purpose of this study was to evaluate the influence of two mechanical treatments followed by seven chemical treatments on the shear bond strength (SBS) of composite resin to zirconia. Materials and Methods In this in vitro study, 280 zirconia blocks (Y-TZP) were either air-abraded or bur roughened and divided into seven experimental groups (n = 20) in terms of primer/resin application: 1) ZPP, Z-Prime Plus; 2) ZPP + GP, Z-Prime Plus followed by G-premio bond; 3) ZPP + ALB, Z-Prime Plus followed by All Bond Universal; 4) ZPP + CLRF, Z-Prime Plus followed by Clearfil SE Bond; 5)GP, G-Premio Bond 6) ALB, All Bond Universal; and 7) CLRF, Clearfil SE Bond. After composite bonding and storage in distilled water (24 hours), half of each group specimen (n = 10) were thermocycled. All specimens were subjected to shear force. Statistical analysis was performed using Kruskal–Wallis and Mann–Whitney test (α = 0.05). Results Significant reduction in SBS was observed in all groups after thermocycling(p < 0.05), except for the air-abraded ZPP + CLRF (p = 0.143). After aging, air-abraded CLRF exhibited the highest SBS (13.55 ± 7.8 MPa) and bur roughened ZPP showed the lowest SBS (1.16 ± 1.23 MPa). In the aged specimens, there was a significant difference between air abrasion and bur roughening in all groups (p < 0.05). Conclusion Air-abrasion followed by application of adhesive (with/without prior primer application) is the most efficient technique for repair of veneered zirconia restorations with resin composite

Evaluation of Shear Bond Strength of Multilayered Zirconia and Lithium Disilicate Ceramic to Resin Cement

“…Our findings showing decreased bond strength post-thermocycling, agreed with similar studies by Lee and Lee (49) Fathpour et al, (50) and Ozcan et al (51) . These studies also concluded that thermocycling universally reduced shear bond values across all tested groups.…”

Evaluation of the Shear Bond Strength of Immediate and Delayed Restorations of Various Calcium Silicate-Based Materials with Fiber-Reinforced Composite Resin Materials

“…In the majority of studies evaluating the SBS values of materials, the values were compared, but their clinical acceptability was not discussed. Some studies accept 9 MPa [39,40] or 10-13 MPa [41][42][43] as an acceptable SBS value, while others have suggested that this value should be at least 17.20 or 18 MPa [38,44]. In addition, a meta-analysis revealed that the clinically acceptable bond strength value for inter-material (composite-composite) adhesion remains unclear [18].…”
