Fracture resistance of implant- supported monolithic crowns cemented to zirconia hybrid-abutments: zirconia-based crowns vs. lithium disilicate crowns
PURPOSE The aim of this in vitro study was to investigate the fracture resistance under chewing simulation of implant-supported posterior restorations (crowns cemented to hybrid-abutments) made of different all-ceramic materials. MATERIALS AND METHODS Monolithic zirconia (MZr) and monolithic lithium disilicate (MLD) crowns for mandibular first molar were fabricated using computer-aided design...
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...
متن کاملFracture Resistance of Lithium Disilicate Ceramics Bonded to Enamel or Dentin Using Different Resin Cement Types and Film Thicknesses.
PURPOSE To investigate the influence of cement film thickness, cement type, and substrate (enamel or dentin) on ceramic fracture resistance. MATERIALS AND METHODS One hundred extracted human third molars were polished to obtain 50 enamel and 50 dentin specimens. The specimens were cemented to 1-mm-thick lithium disilicate ceramic plates with different cement film thicknesses (100 and 300 μm) ...
متن کاملIn vitro study of the fracture resistance of monolithic lithium disilicate, monolithic zirconia, and lithium disilicate pressed on zirconia for three-unit fixed dental prostheses
PURPOSE The purpose of this study was to determine fracture resistance and failure modes of three-unit fixed dental prostheses (FDPs) made of lithium disilicate pressed on zirconia (LZ), monolithic lithium disilicate (ML), and monolithic zirconia (MZ). MATERIALS AND METHODS Co-Cr alloy three-unit metal FDPs model with maxillary first premolar and first molar abutments was fabricated. Three di...
متن کاملEvaluating The Opacity of Two Super high Translucent Zirconia and Lithium Disilicate Reinforced Glass Ceramic
Abstract Background and Aim: The opacity of dental ceramics has important role in final appearance of all ceramic restorations. opacity of super high translucent zirconia is not clearly determined.The aim of this study was evaluating the opacity of two super high translucent zirconia (zolid fx and DD cubeX2 ) and lithium disilicate reinforced glass ceramic(IPS e.max CAD LT). Materials and Metho...
