Influence of Surface Treatments and Adhesive Systems on Lithium Disilicate Microshear Bond Strength.
The purpose of this study was to evaluate the microshear bond strength of ceramic prosthetic structures reinforced by lithium disilicate cemented with resin cement under conditions of different surface treatments and adhesive systems. Seventy-two rectangular blocks of lithium disilicate (6.5 mm long × 5 mm wide × 1 mm thick) were fabricated, air abraded with 50-μm Al2O3 particles and divided in...
متن کاملA Comparison of Tensile Bond Strength between Low Translucency and High Translucency Lithium Disilicate Ceramics Using Two Different Resin Cements
Objectives: To compare two different dual-curing resins cement interfaces between low translucency and high translucency lithium disilicate glass-ceramics in vitro. M~aterials and Methods: ISO 11405 was modeled by using a standardized dumb-bell test to compare the tensile bond strength of two different resin cement interfaces ofa low translucency lithium disilicate ceramic to a high translucenc...
متن کاملThe Effect of Lithium Disilicate Ceramic Thickness and Translucency on Shear Bond Strength of Light-cured Resin Cement
Introduction: To achieve acceptable clinical performance, a ceramic veneer must be bonded to enamel by well-polymerized resin cement. Among different factors, thickness and translucency of the ceramic may affect the resin cement polymerization. Thus, the current study evaluated the effect of the thickness and translucency of lithium disilicate ceramic on light-cured resin cement bond strength t...
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 کاملShear Bond Strength of Porcelain Veneering to Nickel-Chromium, Chromium-Cobalt, Zirconia and Lithium Disilicate
Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...
