The invention relates to a zirconia ceramic implant with periodic pore structure and a preparation method. The zirconia ceramic implant includes an upper half and a lower half, and the raw materials of the upper half include zirconia, alumina, yttrium oxide, silicon dioxide, titanium dioxide, polyethylacryloyl, and trimethylolpropane trioxide. Acrylic acid, dimethylolpropionic acid, epoxy resin; raw materials for the lower part include zirconia, alumina, silica, titania, hydroxyapatite, sodium silicate, polyethylacryloyl, trimethylol Propane triacrylic acid, dimethylol propionic acid, epoxy resin. The preparation method includes mixing of ceramic matrix powder, pre-mixing of auxiliary agents, preparation of upper half of raw materials, preparation of lower half of raw materials, printing of lower half of implant, printing of upper half of implant and sintering of ceramic implant. The zirconia ceramic implant is solid in the upper half and hollow in the lower half with periodic mesh structure, which has high bonding strength with bone, high occlusal end strength and high shear resistance. |
