Zirconium oxide sintered body and method for producing same
Provided are: a zirconia sintered body having both high light transmittance and high strength, which are suitable for use in front teeth and canine teeth (in particular, middle cutting teeth and lateral middle cutting teeth); and a method for producing the zirconia sintered body. The present invention relates to a zirconia sintered body which contains zirconia and a stabilizer capable of suppressing the phase change of zirconia, and which is characterized in that: in the number-based particle size distribution, particles having a particle size of 0.45 [mu] m or more but less than 1 [mu] m are contained in a proportion of 20-50%, the particle size being a diameter passing through the center of gravity of the particles;
本发明提供兼具在门牙和犬牙(尤其是中切齿、侧中切齿)中也能够适宜使用的高透光性和高强度的氧化锆烧结体及其制造方法。本发明涉及氧化锆烧结体，其为包含氧化锆和能够抑制氧化锆相变的稳定剂的氧化锆烧结体，前述氧化锆烧结体的结晶颗粒中，在个数基准的粒径分布中，以20～50％的比例包含粒径为0.45μm以上且小于1μm的颗粒，前述粒径为穿过颗粒重心的直径。
