Abstract

A dental zirconia system to produce translucent zirconia sintered bodies comprises at least two separate zirconia green bodies. At least one zirconia green body comprises zirconium oxide and a lower content of at least one other oxide summing to between 6.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. At least another zirconia green body comprises zirconium oxide and a higher content of at least one other oxide summing to between 7.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. The at least two zirconia green bodies each have at least some particles with a diameter of 100 nanometers to 1000 nanometers. The at least two zirconia green bodies have different amounts of the at least one other oxide with respect to one another.
