- 摘要：
PROBLEM TO BE SOLVED: To solve a problem that a conventional yttria-containing zirconia sintered compact has not compatibility between translucency and strength, and therefore it is not sufficient to be used for artificial tooth or tooth alignment correcting bracket.
SOLUTION: The translucent yttria-containing zirconia sintered compact comprises zirconia containing >4 to 7 mol% yttria, and the sintered compact having &le2.0 &mum particle diameter and &ge99.5% relative density has compatibility between strength and translucency wherein all light transmissivity to the visible ray of 600 nm wavelength in 1 mm thickness is &ge40% and three point bending strength is &ge500 MPa, and it is used as dental materials such as artificial tooth or tooth alignment correcting bracket.
