“…Unfortunately, zirconia in particular is an acid-resistant ceramic. Thus, it is not sensitive to topographic changes by acid etching in order to achieve adequate micromechanical retention (Kern and Wegner, 1998;Özcan and Vallittu, 2003;Kern, 2009;Thompson et al, 2011). In order to compensate for this, adhesive cements containing functional monomers, air-abrasion by means of alumina or with silica coated alumina particles, has been suggested to clean the zirconia surface and promote adhesion of the resin cements (Kern, 2009).…”

This study evaluated the effect of air-particle abrasion protocols on the biaxial flexural strength, surface characteristics and phase transformation of zirconia after cyclic loading. Disc-shaped zirconia specimens (Ø: 15mm, thickness: 1.2mm) (N=32) were submitted to one of the air-particle abrasion protocols (n=8 per group): (a) 50 m Al2O3 particles, (b) 110 m Al2O3 particles coated with silica (Rocatec Plus), (c) 30 m Al2O3 particles coated with silica (CoJet Sand) for 20s at 2.8bar pressure. Control group received no air-abrasion. All specimens were initially cyclic loaded (×20,000, 50N, 1Hz) in water at 37°C and then subjected to biaxial flexural strength testing where the conditioned surface was under tension. Zirconia surfaces were characterized and roughness was measured with 3D surface profilometer. Phase transformation from tetragonal to monoclinic was determined by Raman spectroscopy. The relative amount of transformed monoclinic zirconia (FM) and transformed zone depth (TZD) were measured using XRD. The data (MPa) were analyzed using ANOVA, Tukey's tests and Weibull modulus (m) were calculated for each group (95% CI). The biaxial flexural strength (MPa) of CoJet treated group (1266.3±158(A)) was not significantly different than that of Rocatec Plus group (1179±216.4(A,B)) but was significantly higher than the other groups (Control: 942.3±74.6(C); 50 m Al2O3: 915.2±185.7(B,C)). Weibull modulus was higher for control (m=13.79) than those of other groups (m=4.95, m=5.64, m=9.13 for group a, b and c, respectively). Surface roughness (Ra) was the highest with 50 m Al2O3 (0.261 m) than those of other groups (0.15-0.195 m). After all air-abrasion protocols, FM increased (15.02%-19.25%) compared to control group (11.12%). TZD also showed increase after air-abrasion protocols (0.83-1.07 m) compared to control group (0.59 m). Air-abrasion protocols increased the roughness and monoclinic phase but in turn abrasion with 30 m Al2O3 particles coated with silica has increased the biaxial flexural strength of the tested zirconia. 942.3±74.6 C ; 50 µm Al 2 O 3 : 915.2±185.7 B,C ). Weibull modulus was higher for control (m=13.79) than those of other groups (m=4. 95, m=5.64, m=9.13 for group a, b and c, respectively). Surface roughness (R a ) was the highest with 50 µm Al 2 O 3 (0.261 µm) than those of other groups (0.15-0.195 µm). After all air-abrasion protocols, F M increased (15.02-19.25%) compared to control group (11.12%). TZD also showed increase after air-abrasion protocols (0.83-1.07 µm) compared to control group (0.59 µm). Air-abrasion protocols increased the roughness and monoclinic phase but in turn abrasion with 30 µm Al 2 O 3 particles coated with silica has increased the biaxial flexural strength of the tested zirconia.

“…This is related to glass-free composition structure, characterizing zirconia as acid-resistant material [8]. For this reason, there have been considerable efforts by many manufacturers and researchers to modify the surface properties of zirconia, mechanically and chemically by various surface treatments [9][10][11][12].…”

“…Several techniques, especially the airborne particle abrasion with alumina, have been reported to facilitate "mechanically" the bond strength between resin cement and Y-TZP ceramic [9][10][11][12]. In addition, tribochemical silica coating in dental laboratories was suggested as an effective method for bonding [9,10], but recently, it has also been criticized for possibility of subcritical crack propagation within zirconia [13][14][15].…”

“…Thus, depending on the microstructure of the ceramic used to manufacture the dental restoration, it can effectively be treated for conventional or adhesive cementation, either with hydrofluoric acid etching, or airborne particle abrasion, and also using a silica coating technique. Together with those surface conditioning methods, silane application has been considered effective in the conditioning method for bonding resin composites to oxide ceramics [17].…”

OBJECTIVES: The aim of this study was to evaluate the effect of different seating forces during cementation in cement-ceramic microtensile bond strength ( TBS). MATERIALS AND METHODS: Forty-five blocks (5 × 5 × 4 mm(3)) of a glass-infiltrated alumina-based ceramic (In-Ceram Alumina) were fabricated according to the manufacturer's instructions and duplicated in resin composite. Ceramic surfaces were polished, cleaned for 10 min in an ultrasonic bath, silica coated using a laboratory type of air abrasion device, and silanized. Each treated ceramic block was then randomly assigned to five groups (n = 9) and cemented to a composite block under five seating forces (10 g, 50 g, 100 g, 500 g, and 750 g) using a dual-cured resin cement (Panavia F). The ceramic-cement-composite assemblies were cut under coolant water to obtain bar specimens (1 mm × 0.8 mm(2)). The TBS tests were performed in a universal testing machine (1 mm/min). The mean bond strengths values were statistically analyzed using one-way ANOVA ( 0.05). RESULTS: Different seating forces resulted in no significant difference in the TBS results ranging between 13.1 ± 4.7 and 18.8 ± 2.1 MPa (p = 0.13) and no significant differences among cement thickness. CONCLUSIONS: Excessive seating forces during cementation seem not to affect the TBS results. CLINICAL RELEVANCE: Excessive forces during the seating of single all-ceramic restorations cementation seem to display the same tensile bond strength to the resin cement.

Different seating forces resulted in no significant difference in the µTBS results ranging between 13.1±4.7 and 18.8±2.1 MPa (p=0.13) and no significant differences among cement thickness. Conclusions. Excessive seating forces during cementation seem not to affect the µTBS results.Clinical relevance. Excessive forces during the seating of single all-ceramic restorations cementation seem to display the same tensile bond strength to the resin cement.
