In 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 کاملFracture 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 کاملFracture resistance of monolithic zirconia molar crowns with reduced thickness.
OBJECTIVES The purpose of the present study was to analyze the relationship between fracture load of monolithic zirconia crowns and axial/occlusal thickness and to evaluate the fracture resistance of monolithic zirconia crowns with reduced thickness in comparison with that of monolithic lithium disilicate crowns with regular thickness. MATERIALS AND METHODS Monolithic zirconia crowns (Lava Pl...
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...
متن کاملThe Effect of Different Marginal Designs on the Fracture Resistance of Monolithic Zirconia Crowns
Abstract Background and Aim: One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. The aim of the present in vitro study is to compare the effect of three marginal designs (shoulder, sloped shoulder, chamfer) on the fracture resistance of monolithic zirconia crowns. Materials and methods: In this in vitro study, three PEEK dies with cham...
