Somaraj V: Esthetic Rehabilitation using Zirconia-Based All-Ceramic Crown
The dental practice is not only about prevention and treatment of oral diseases but also the fulfillment of demands of all who seek oral care, of which esthetics weighs more importance than any. To achieve excellence in the delivery of dental care, dentists rely on the vast array of modern advances in dental materials and restoration fabrication technologies. Need for more esthetical, metal-fre...
متن کاملEffect of Zirconia Thickness on the Tensile Stress of Zirconia Based All-Ceramic Restorations
Introduction: The purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. Methods: Twenty zirconia disks with 10mm diameter were prepared in two groups using CAD/CAM system. The thickness of zirconia was 0.5mm in first group and 0.3mm in second group. After sintering, 0.4mm glass ceramic porcelain was appl...
متن کاملChairside Fabrication of an All-Ceramic Partial Crown Using a Zirconia-Reinforced Lithium Silicate Ceramic
The chairside fabrication of a monolithic partial crown using a zirconia-reinforced lithium silicate (ZLS) ceramic is described. The fully digitized model-free workflow in a dental practice is possible due to the use of a powder-free intraoral scanner and the computer-aided design/computer-assisted manufacturing (CAD/CAM) of the restorations. The innovative ZLS material offers a singular combin...
متن کاملThe effect of zirconia framework design on the failure of all-ceramic crown under static loading
PURPOSE This in vitro study aimed to compare the failure load and failure characteristics of two different zirconia framework designs of premolar crowns when subjected to static loading. MATERIALS AND METHODS Two types of zirconia frameworks, conventional 0.5 mm even thickness framework design (EV) and 0.8 mm cutback of full contour crown anatomy design (CB), were made for 10 samples each. Th...
متن کاملComparison of the translucency of shaded zirconia all-ceramic systems
PURPOSE The purpose of this study was to evaluate and compare the translucency of shaded zirconia all-ceramic systems. MATERIALS AND METHODS Translucency of 3 different zirconia all-ceramic systems colored by different techniques was compared with a lithium disilicate glass-ceramic (IPS e.max Press). Square-shaped specimens with 0.5 mm thickness were fabricated from In-Ceram YZ, ICE Zirkon an...
