“…In the current study, omitting the air-borne particle abrasion resulted in much lower SBS values. The same conclusion was drawn by other authors [2,5,16,18,22,25,27]. Moreover, they confirm not only the lower SBS values of zirconia to resin cements, but also the adhesive interface degradation due to the hydrolysis in case the alumina air-abrasion is omitted [22,25].…”

“…In the current study, using the air-borne particle abrasion with 250 µm alumina particles resulted in higher SBS values when AZ-Primer was applied on the zirconia surface. El-Shrkawy et al proved that for Multilink Automix resin cement, the additional air-abrasion with 110 µm alumina particles resulted in twice as high bond strength values than for untreated zirconia specimens (13.2 MPa vs. 6.1 MPa) [5]. On the other hand, Kitayama et al compared the bond strength of five different resin cements to zirconia-based ceramics with and without additional primer application; prior to adhesive cementation, they treated the zirconia surface with 70 µm alumina air-abrasion.…”

“…Phosphate monomers exhibit chemical affinity for zirconium oxide [8,13,24]. However, such primer bonding efficacy is satisfactory when combined with air-borne particle abrasion with alumina particles [2,5,7,13,16,18,22,27,28]. Omitting air abrasion results in a decrease in bond strength, even bonding failure [2,5,16,18,22,25,27].…”

A B S T R AC TIntroduction: The loss of retention of zirconia-based fixed partial dentures (FPDs) is one of the most frequently reported failures. Objectives: The purpose of this study was to evaluate the shear bond strength (SBS) of four resin cements to zirconia after air-borne particle abrasion with alumina of different grades and application of respective primers incorporating organophosphate monomers. Material and methods: The 443 cuboid-shape zirconia specimens (Ceramill Zi; Amann Girrbach AG) were divided into 16 research groups, according to the chemo-mechanical modification: air-abrasion with alumina particles of 50 μm, 110 μm or 250 μm grade, no treatment and application of primers and resin cements: Clearfil Ceramic Primer/Panavia F2.0 (Kuraray Medical), Monobond Plus/Multilink Automix (Ivoclar Vivadent AG), AZ-Primer/ResiCem (Shofu), Z-Prime Plus/Duo-Link (Bisco). After storage in 37 ± 1°C distilled water for 24 hours, the SBS test was conducted (Zwick/Roell Z005; Zwick GmbH&Co.KG) at 1 mm/min crosshead speed to failure. Specimens were subjected to fractographic analysis at ×2.5 and ×35 magnification (Seliga Auctus; Seliga Microscopes Sp.z o.o.; SEM S-4700; Hitachi High-Technologies Corporation). Statistical significance was established with the Wilcoxon signed-rank test and the Kruskal-Wallis one-way analysis of variance (p = 0.05). Results: The highest SBS values of zirconia to resin cement were obtained for Z-Prime Plus/DuoLink and after 50 μm alumina air-abrasion (6.87-14.15 MPa). However, the alumina particle grade was insignificant. A significant decrease in the SBS was observed for untreated specimens (4.60-8.24 MPa). The failure mode in untreated specimens was mainly adhesive, while in sandblasted it was cohesive and mixed. Conclusions: The chemo-mechanical treatment of zirconia surface before adhesive cementation is crucial to obtain satisfactory values of shear bond strength to resin cements.

“…[4][5][6] In studies on reinforcing the shear bond of zirconia ceramic to resin composites, results have shown that sandblasting, lasers and universal bonding can be used to strengthen the bond. 7 Erbium lasers were introduced as an alternative to conventional mechanical tools for cutting dental surfaces in dentistry. These lasers can absorb radiation energy at a range of 2.6 and 3 μm, which is the strongest water absorption range and the most important component of hard dental tissues.…”

Aim:The purpose of this study was to investigate the effect of Erbium-doped yttrium aluminium garnet laser laser (Er: YAG laser), sandblast and several universal bonding on the shear bond strength of zirconia ceramic to composite resin. Materials and methods:In this experimental study, 96 Y-TZP disks were used. They were divided into six groups based on surface preparation: 1-Er: YAG laser + single bond universal/ 3M, 2-Er: YAG laser + all bond universal/bisco, 3-Er: YAG laser + G-premio bond/GC, 4-sandblast + single bond universal/3M, 5-sandblast + all bond universal/bisco, 6-sandblast + G-Premio bond/GC; in the next step, composite discs were cured on the surface of the zirconia discs and their shear bond strength was evaluated using a mechanical test machine (universal testing machine).Results: Two-way ANOVA showed that the surface preparation had a significant statistical effect on shear bond strength (p< 0.001). There was no association between these two variables with regards to the interaction of bonding and surface preparation (p = 0.064). Tukey's test showed that the shear bond strengths in the sandblast type group did not differ significantly between the groups according to the type of universal bonding, as well as in the Er: YAG laser treated group by type Universal bonding which was not significantly different between the groups of single bond universal and all bond universal, but there was a significant difference between the groups in terms of single bond universal and G-Premio, as well as all bond universal and G-Premio. Conclusion:Based on the results, the preparation of Er:YAG laser is a more appropriate method for increasing bond strength when compared with sandblasting, and among the universal bonding, G-Premio is also more suitable for this purpose. Clinical significance:The present data indicate that bond strength of laser preparation and G-Premio adhesive might be reliable for clinical application

Enhanced Bonding via Additive Manufacturing‐Enabled Surface Tailoring of 3D Printed Continuous‐Fiber Composites

et al. 2018

Additive manufacturing (AM) of composites, particularly continuous fiber composites as studied here, is emerging as a new paradigm for creating advanced structures. Traditional machining and joining approaches will evolve or be fully displaced by AM approaches, and here the authors introduce a seminal investigation into AM‐enabled bonding/joining of continuous fiber composite laminates/multilayers. The AM‐enabled tailoring approach volumetrically increases surface area available for bonding by ∼150% by printing lines of continuous Nylon matrix filaments at an infill density of 50% to create a porous (∼50 vol%) bonding surface, rather than the conventional/baseline solid (100 vol%) surface approach. The AM‐tailored multilayers show improvements relative to the baseline single‐lap‐joint (SLJ) multilayer, and versus the industry‐standard surface preparation approach: 550% and 145% increases in ultimate strength, 10 000% and 800% increases in toughness, respectively, while maintaining joint stiffness. Benchmark mechanical performance data is established via the AM‐tailored bonding approach for carbon, glass, and Kevlar continuous fiber reinforced additively manufactured composite SLJ multilayers. AM‐enabled enhanced joining, such as the concept demonstrated here, is critical as AM components are increasingly being joined, both to each other and to other (non‐AM, different AM, etc.) structures in advanced applications.
