“…Many researchers are engaged in the study of techniques to promote better adhesion between zirconia and resin cement. Several procedures have been suggested for this purpose such as silica deposition by plasma [8], selective infiltration etching [9], use of cements and adhesives based on 10-methacryloyloxy-decyl dihydrogenphosphate (MDP) [10], glaze application followed by etching [11] and air-borne particle abrasion [12]. Among all these methods, air-abrasion protocol is a simple, inexpensive technique that can be performed chairside [12].…”

OBJECTIVES This study evaluated the influence of air-particle abrasion protocols on the surface roughness (SR) of zirconia and the shear bond strength (SBS) of dual-polymerized resin cement to this ceramic. MATERIALS AND METHODS Sintered zirconia blocks (n = 115) (Lava, 3M ESPE) were embedded in acrylic resin and polished. The specimens were divided according to the 'particle type' (Al: 110 µm Al2O3; Si: 110 µm SiO2) and 'pressure' factors (2.5 or 3.5 bar) (n = 3 per group): (a) Control (no air-abrasion); (b) Al2.5; (c) Si2.5; (d) Al3.5; (e) Si3.5. SR (Ra) was measured 3-times from each specimen after 20 s of air-abrasion (distance: 10 mm) using a digital optical profilometer. Surface topography was evaluated under SEM analyses. For the SBS test, 'particle type', 'pressure' and 'thermocycling' (TC) factors were considered (n = 10; n = 10 per group): Control (no air-abrasion); Al2.5; Si2.5; Al3.5; Si3.5; ControlTC; Al2.5TC; Si2.5TC; Al3.5TC; Si3.5TC. After silane application, resin cement (Panavia F2.0) was bonded and polymerized. Specimens were thermocycled (6.000 cycles, 5-55°C) and subjected to SBS (1 mm/min). Data were analyzed using ANOVA, Tukey's and Dunnett tests (5%). RESULTS 'Particle' (p = 0.0001) and 'pressure' (p = 0.0001) factors significantly affected the SR. All protocols significantly increased the SR (Al2.5: 0.45 ± 0.02; Si2.5: 0.39 ± 0.01; Al3.5: 0.80 ± 0.01; Si3.5: 0.64 ± 0.01 µm) compared to the control group (0.16 ± 0.01 µm). For SBS, only 'particle' factor significantly affected the results (p = 0.015). The SiO2 groups presented significantly higher SBS results than Al2O3 (Al2.5: 4.78 ± 1.86; Si2.5: 7.17 ± 2.62; Al3.5: 4.97 ± 3.74; Si3.5: 9.14 ± 4.09 MPa) and the control group (3.67 ± 3.0 MPa). All TC specimens presented spontaneous debondings. SEM analysis showed that Al2O3 created damage in zirconia in the form of grooves, different from those observed with SiO2 groups. CONCLUSIONS Air-abrasion with 110 µm Al2O3 resulted in higher roughness, but air-abrasion protocols with SiO2 promoted better adhesion. AbstractObjectives.

“…Ntala et al in 2010 applied a glaze coating containing hydroxy apatite to some specimens and noticed that acid etching of these specimens yielded a completely cracked surface providing no mechanical retention for the adhesive. They concluded that this material was not suitable for enhancing zirconia bonding 17) . In our study, emergence of cracks after etching may be related to the presence of phosphate-rich phases.…”

“…Adequate bond to zirconia has been the subject of many investigations in the recent years 9,10) . Since the introduction of zirconia, several techniques have been suggested to enhance its bond strength to resin cement; these include surface abrasion with burs and abrasive papers and sandblasting 11) , silica (tribochemical) coating [12][13][14] , silicoating 15) , using glass micropearls 16) , glazing [17][18][19][20] , selective infiltration etching technique 21) , hot etching 22,23) , use of phosphate-ester monomers 10,24) and laser irradiation 25) . Despite extensive studies in this field, the only consensus reached is that hydrofluoric (HF) acid etching and silanization are not effective for zirconia ceramics and there is no specific surface treatment to maximize bonding to zirconia 26) .…”

This study aimed to assess the effect of bioglass and silica coating of zirconia substrate on its bond strength to resin cement. A total of 120 specimens were used in this in-vitro, experimental study. Zirconia discs measuring 10×7×2 mm were cut from Y-TZP zirconia blocks, sintered, cleaned and received different surface treatments of sandblasting, bioglass powder coating+etching, bioglass powder coating+etching+silanization, bioglass slurry coating+etching, bioglass slurry coating+etching+silanization, silica coating+silanization, silica coating+etching+silanization and no treatment group (control). Then the microshear bond strength testing and scanning electron microscope (SEM) analysis were done. Data were analyzed using the Mann Whitney U and the Kruskal Wallis tests. Significant differences existed in bond strength of different groups (p<0.001). The sandblasted and bioglass coated groups showed higher and the colloidal silica-coated groups showed lower bond strength compared to the control group.

“…Yet, studies have shown that laser irradiation is not as effective as air-borne particle abrasion methods in improving adhesion of resin cements to zirconia [21]. Other coating methods using micropearls of low fusing ceramic or vapor deposition of silicon tetrachloride (SiCl 4 ) have shown worthy results of adhesion [22] but again glass deposition was found critical to interfere with the internal adaptation of the reconstruction [23][24].…”

Yttrium-stabilized zirconium dioxide, a commonly used material in conjunction with CAD/CAM technologies in dentistry, is an oxide ceramic that does not comprise silicon dioxide (SiO 2 ) phase in its microstructure. Since it is challenging to create durable adhesion between resin cements and this kind of nonetchable ceramic, efforts have been made to develop innovative surface conditioning methods over the years.While some chemical methods based on using adhesion promoters only did not perform stable adhesion, others utilizing physico-chemical conditioning methods provided better adhesion where the latter is also being questioned on impairing mechanical stability of zirconium dioxide (ZrO 2 ) due to t→m phase transformation.This review will highlight current surface conditioning concepts to achieve best adhesion to zirconium dioxide, challenges related to conditioning methods or resin-based luting cements, and contemplate on future prospects.
