Zirconia pre-sintered body suitable for dental use

A zirconia pre-sintered body, comprising:

• a multilayer structure including at least three layers containing zirconia and a stabilizer capable of reducing a phase transformation of zirconia, wherein
• the zirconia comprises predominantly monoclinic crystal system,
• the multilayer structure comprises at least two layers having different stabilizer contents relative to a total mole of the zirconia and the stabilizer and the difference in the stabilizer contents is 0.1 mol % or more and 3.0 mol % or less,
• in the layers having different stabilizer contents, the stabilizer content relative to the total mole of the zirconia and the stabilizer shows an unchanging pattern of increase or decrease on a straight line extending along a direction from one end to the other end of the zirconia pre-sintered body, and the stabilizer content relative to the total mole of the zirconia and the stabilizer is 3.5 mol % or more and 6.5 mol % or less in the layer including said one end, and is 2.5 mol % or more and less than 4.5 mol % in the layer including said other end,
• the multilayer structure comprises at least two layers having substantially the same stabilizer content relative to the total mole of the zirconia and the stabilizer,
• the zirconia pre-sintered body contains a color component in all of the layers having substantially the same stabilizer content, and
• the layers having substantially the same stabilizer content have different color component compositions.
