The invention relates to the technical field of ceramic materials, and particularly relates to a denture material and a preparation method thereof. The preparation method of the denture material comprises the following steps: concentrating the yttria-stabilized zirconia suspension containing the dispersing agent, then carrying out molding treatment in a mold, drying to obtain a zirconia green body, and then carrying out degumming and sintering. The invention can keep the superfine nanometer grain diameter of the raw material powder by a wet forming method, ensures that the sintered denture porcelain block has uniform internal structure, the grain size is less than 100 nanometers, the fracture strength is high, the toughness is good, and the yield and the mechanical property of the denture material are effectively improved. |
