Abstract:
A zirconia ceramic material for use in dental applications is provided comprising an yttria-stabilized zirconia material comprising from 4.5 mol % to 5.1 mol % yttria. Optionally, the zirconia ceramic has a coloring agent that may comprise one or more metals selected from terbium (Tb), chromium (Cr), erbium (Er), and cobalt (Co), and further, may, optionally, comprise alumina, which if present may be in an amount from 0 wt % to 0.25 wt %. The zirconia ceramic materials exhibit both enhanced translucency and a flexural strength of at least 800 MPa when fully sintered.
