Abstract
A zirconia sintered body may have less excess material to be removed when making a prosthesis by milling, and may provide a reduction of work time, more durability for a working tool, and a faster treatment for patients, and may undergo little deformation during firing, and provide enhanced aesthetics. A columnar zirconia sintered body may have a base and a side face, the base having a surface shape that is neither square nor rectangular but has at least one straight portion.
