Rebholz-Zaribaf, Nasanin; Özcan, Mutlu (2017). Adhesion to zirconia as a function of primers/silane coupling agents, luting cement types, aging and test methods. Journal of Adhesion Science and Technology, 31(13):1408-1421.

Abstract

This study evaluated the adhesion of resin cements to zirconia with different primers/silane coupling agents using two test methods with and without aging. Zirconia discs (Cercon) (N = 900, n = 15 per group) were ground finished to 2000 grit silicone carbide and randomly divided into seven groups: (a) C: No treatment (Control), (b) SG: Signum, (c) CL: Clearfil Ceramic Primer, (d) AP: Alloy Primer, (e) Monobond Plus, (f) ES-R: ESPE-Sil after Rocatec and (g) ES-C: ESPE-Sil after CoJet. Methacrylate (Variolink II-VL) and MDP based (Panavia F2.0-PN) dual-polymerized and self-adhesive resin cements (RelyX Unicem-RX) were adhered and polymerized accordingly. The specimens were further randomly divided into two groups to be tested after (a) 24-h dry storage at 37 °C and (b) thermocycling (×5000, 5–55 °C). Macroshear (MSB) and macrotensile bond tests (MTB) were conducted in an universal testing machine (crosshead speed: 1 mm/min) and failure types were analyzed after debonding. Data were analyzed using Univariate analysis and Tukey’s tests (α = 0.05). Two-parameter Weibull modulus, scale (m) and shape (0) were calculated. While primer/silane (p < 0.001), cement type (p < 0.001) and aging (p < 0.001) significantly affected the bond results, test method did not show significant difference (p = 0.237). In MSB test, Weilbul moduli were more favorable for MP-VL (4.2) and AP-PN (6) combinations and after aging for MP-VL (4.2) and AP-PN (5.66). In MTB test, after aging, Weilbul moduli were more favorable for AP-PN (5.41). Bond strength results mostly decreased with SG (24–92%) after aging. Cohesive failures in the cement were more frequent with PN (252) compared to VL (83).
