![]() ![]() Fortress® is a leucite-reinforced system with increased fracture resistance and opacity due to leucite crystals. They require good moister control rendering subgingival margins a relative contraindication. The all-ceramic restoration is bonded to underlying dentin/enamel using dual-cure resin-based luting cement with the mediating bond created by dentin bonding agents and micro mechanically retentive ceramic surface (Burke 1996). The feldspathic porcelain is fired onto a refractory or platinum foil die by layering (stacking). Feldspathic Porcelains (Dentin/Resin-bonded crowns/veneers) Zirconium-based system (Porcelain fused to CAD/CAM Zirconia coping) I. Alumina-based systems (In-Ceram®, Tech-Ceram®, Procera All-Ceram®) A coping to which glass-ceramic is layered or pressed In-surgery CAD/CAM (CEREC ®= CEramic REConstruction) II. This article describes the diverse clinical, mechanical, aesthetical, and laboratory-related characteristics of all-ceramic Substructures respective Supra-structures utilised in modern cosmetic dentistry.Īll-ceramic systems are classified according to the fabrication techniques, which may include: I. IPS e.max Zircad, with the excellent aesthetic qualities of Silicate ceramics, e.g. The IPS e.max ceramic system, excelling the IPS Empress 2 system, combines the advantages of the Zirconium Oxide ceramics (ZrO2), e.g. ![]() ![]() ![]() Whereas, Oxide ceramics, specifically Zirconium Oxide ceramics, are used in the posterior area, where functional forces require higher flexural strength. Silicate ceramics could be used in porcelain laminate veneers and crowns in the anterior region to provide excellent aesthetics. With the advent of all-ceramic restoration modalities, allowing for a simultaneous fabrication of both ceramic framework and porcelain veneer, modern cosmetic dentistry could benefit from a selection of the ideal all-ceramic structures encompassing both function and aesthetics. ![]()
