Colored Translucent Zirconia Sintered Body And Powder, And Use Thereof

Colored translucent zirconia sintered body for dental applications that mimics the aesthetics of natural teeth. The sintered body contains zirconia with specific compositions of yttria, erbia, cobalt, iron, and aluminum. The compositions provide translucency, strength, and stability for dental use without needing porcelain layering. The zirconia powder is molded and sintered under normal pressure. This allows producing translucent zirconia dental parts like front teeth that have natural tooth-like color and transparency. The compositions also prevent color change in the oral environment.
