In the search for the ultimate esthetic restorative material, many all-ceramic systems have been proposed. Dental research is nowadays directed toward metal-free prosthetic restorations in order to improve an esthetical outcome of crown and bridge restorations. Zirconia is a polycrystalline ceramic without a glassy phase and exists in several forms. Zirconia cores for fixed partial dentures (FPD) on anterior and posterior teeth and on implants are now available. This article is a review of zirconia crowns as replacement for conventional metal-ceramic crowns.

“…In vitro research evaluating the influence of processing variables on the fracture resistance of all ceramic restorations has revealed highly divergent failure loads of 450 to 1600 N for zirconia single crown copings, depending on coping thickness, marginal design, and luting agent. 15,16 In a study where zirconia was used with a 0.5 mm layer thickness as a framework for primarily posterior 3 to 5-unit fixed partial dentures, failures were attributed to cracking or crazing of the veneering porcelain, while bulk fractures were uncommon. 10 Fracture appears to be the most common clinical failure mechanism affecting all ceramic crowns.…”

Background: An in vitro study was performed to assess the effect of three implant abutment angulations and three core thicknesses on the fracture resistance of overlaying computer-aided manufacturing (CAM) milled zirconia (Cercon Ò system) single crowns. Methods: Three groups, coded A to C, with different implant abutment angulations (group A ⁄ 0°, group B ⁄ 15°and group C ⁄ 30°angulation) were used to construct 15 crowns for each angulation. Forty-five overlay restorations were milled using the Cercon Ò system with zirconium core thicknesses of 0.4, 0.6 and 0.8 mm using five crowns for each angulation. The final restorations were prepared and stored in distilled water at mouth temperature (37°C) for 24 hours prior to testing. The restorations were cemented using Temp Bond

“…For example, a mean marginal gap of 65 μm was reported for fixed partial dentures (FPDs) milled from Lava zirconia (3M ESPE, Seefeld, Germany) in a semi-sintered state 17) . Fracture toughness of all-ceramic crowns is also an important property that has a direct correlation to their clinical success, and hence a keenly investigated subject in numerous in vitro studies [19][20][21] . Regarding the effect of luting cements on the fracture resistance of all-ceramic crowns, it remains a controversial and widely debated issue.…”

This study evaluated the marginal adaptation and fracture resistance of CAD/CAM-fabricated zirconia crowns luted using different luting agents. Twenty crown restorations were produced using IPS ZirCAD zirconium oxide blocks (IZC), and another 20 using Lava zirconium oxide blocks (L). Ten teeth were used as control. Luting agents used were an etch-and-rinse adhesive (Variolink II) and a self-etch adhesive (Multilink Automix). Internal and marginal adaptation was evaluated using silicone replica technique. Fracture resistance was evaluated using a compression test. Marginal discrepancy was 89.26 μm for L crowns and 88.84 μm for IZC crowns, and difference was statistically insignificant. However, L crowns showed significantly larger axial and occlusal gaps than IZC crowns (p<0.05). Fracture resistance of IZC-Multilink was higher than the other groups, although the difference was not significant. Results showed that CAD/CAM-fabricated crowns showed acceptable in vitro marginal discrepancies and fracture strengths.
