A zirconia-based antibacterial denture material, comprising components with the following mass parts:
- 75 to 80 parts of zirconium oxide, 2 to 5 parts of nanosized silver oxide, 3 to 5 parts of nanosized zinc oxide, 1 to 3 parts of nanosized lanthanum oxide, 1 to 3 parts of nanosized yttrium oxide, 1 to 2 parts of cerium oxide, and 1 to 2 parts of size control agent.
A preparation method of a zirconia-based antibacterial denture material, comprising:
- weighing zirconium oxide, silver oxide, zinc oxide, lanthanum oxide, yttrium oxide, cerium oxide and size control agent in proportion, and mixing by ball milling, to obtain ceramic powder;
- putting the ceramic powder into a mold and pre-pressing the ceramic power to obtain an antibacterial denture porcelain block precursor;
- and
- performing cold isostatic pressing, pre-sintering, and high-temperature sintering on the antibacterial denture porcelain block precursor to obtain the zirconia-based antibacterial denture material.
