Monolithic Zirconia for Prosthetic Reconstructions: Advantages and Limitations [PDF]

open access: yesCurrent Oral Health Reports, 2017
Due to frequent clinical reports on chipping of the veneering ceramic applied on zirconia frameworks, non-veneered monolithic zirconia has been proposed in an attempt to improve the lifetime of metal-free fixed dental prostheses (FDPs). This review highlights the effects of microstructure and chemical composition on optical properties and mechanical ...
