Resistance to bond degradation between dual-cure resin cements and pre-treated sintered CAD-CAM dental ceramics
OBJECTIVE To evaluate the bond stability of resin cements when luted to glass-reinforced alumina and zirconia CAD/CAM dental ceramics. STUDY DESIGN Eighteen glass-infiltrated alumina and eighteen densely sintered zirconia blocks were randomly conditioned as follows: Group 1: No treatment; Group 2: Sandblasting (125 µm Al₂O₃-particles); and Group 3: Silica-coating (50 µm silica-modified Al₂O₃-...
متن کاملPolymerization efficiency of two dual-cure cements through dental ceramics
PURPOSE The aim of this study was to evaluate the effect of thickness of zirconia on curing efficiency of resin cements. MATERIALS AND METHODS Four discs with 4.0 mm in diameter were prepared from non-HIP translucent zirconia blocks using a CAD/CAM system and feldspathic ceramic was layered onto discs. Thus, 4 ceramic disc samples were fabricated: (G) 0.5 mm zirconia- as a control group, (G1)...
متن کاملEffect of thermocycling on the bond strength between dual-cured resin cements and zirconium-oxide ceramics.
The present study evaluated the durability of bond strength between zirconia and 3 different resin cements. Thirty stabilized tetragonal zirconium-dioxide blocks were duplicated in dual-curing resin core build-up material specimens. Resin blocks were randomly luted to zirconium surfaces using 1) Clearfil Esthetic Cement (CLF), 2) RelyX Unicem Aplicap (RELX), or 3) Multilink Automix (MLA). After...
متن کاملPost‐etching cleaning influences the resin shear bond strength to CAD/CAM lithium‐disilicate ceramics
Background Bonding to silica-based ceramics requires micro mechanical (hydrofluoric-acid, HFetching) and chemical (silane) coupling [1–5]. The HF-etching provides dissolution of Abstract Statement of problem: The hydrofluoric acid (HF) is able to promote selective dissolution of the glassy phase in silica-based ceramic. However, the etching leaves insoluble silica-fluoride salts in the surface ...
متن کاملEffect of hydrofluoric acid concentration and etching time on microtensile bond strength of suprinity and enamic CAD/CAM ceramics to resin cement
Introduction: The use of dental ceramics has increased due to their beauty and biocompatibility. The aim of this study was to evaluate the effect of hydrofluoric acid concentration and etching time on microtensile bond strength (μTBS) of the Enamic and Suprinity ceramics. Material & Methods: In this in vitro study, two hydrofluoric acid (HFA) concentrations of 5% (A) and 10% (B) were used at t...
