摘要: Objectives: The aim of this study was to evaluate bond strengths zirconium-oxide (zirconia) ceramic and a selection different composite resin cements. Study Design: 130 Lava TM cylinders were fabricated. sandblasted with 80 µm aluminium oxide or silica coated CoJet Sand. Silane, bonding agent and/or Clearfil Ceramic Primer applied. One hundred thirty cement cylinders, comprising two dual-polymerizing (Variolink II Panavia F) autopolymerizing (Rely X Multilink) resins bonded the samples. A shear test conducted, followed by an optical microscopy identify location type failure, electron (SEM TEM) statistical analysis using Kruskal-Wallis for more than independent samples Mann-Whitney Given large number combinations, Bonferroni correction applied (?=0.001). Results: Dual-polymerizing cements provided better adhesion values (11.7 MPa) (7.47 (p-value M-W<0.001). worst techniques + sandblasting Silane Rely X; Multilink silane Multilink. Adhesive failure (separation ceramic) produced at lesser force cohesive (fracture cement) Electron confirmed that surface treatments modified ceramic, creating rough retentive surface, thus providing improved micromechanical interlocking between ceramic.
