Zirconia is a polycrystalline ceramic without a glassy phase and exists in several forms. Recently, zirconia has been used to fabricate ceramic fixed dental prosthesis FDPs with relatively high strength and good aesthetics.  The aim of this systematic review was to assess zirconia-based FDPs in terms of survival and complications. Veneering techniques for porcelain application [read the full story…]
