Problems solved by technology

[0003] The zirconia ceramic implant in the prior art is a solid body with a single upper and lower parts. In order to ensure the fusion of the implant and bone tissue, it takes longer to fix the implant with bone tissue, which increases the restoration cycle of the implant and increases the number of zirconia ceramic implants. The amount of material used increases production costs

Abstract

The invention relates to a zirconia ceramic implant with a periodic pore structure and a preparation method thereof. The zirconia ceramic implant comprises an upper half part and a lower half part, and the upper half part comprises the following raw materials: zirconia, aluminum oxide, yttria, silicon dioxide, titanium dioxide, polyethylacryloyl, trimethylolpropane triacrylate, dimethylolpropionicacid and epoxy resin; and the lower half part comprises the following raw materials: zirconia, aluminum oxide, silicon dioxide, titanium dioxide, hydroxyapatite, sodium silicate, polyethylacryloyl, trimethylolpropane triacrylate, dimethylolpropionic acid and epoxy resin. The preparation method comprises the following steps: mixing of ceramic matrix powder, premixing of auxiliary agents, preparation of the upper half part raw materials, preparation of the lower half part raw materials, printing of the lower half part of the implant, printing of the upper half part of the implant and sinteringof the ceramic implant. The zirconia ceramic implant has a solid upper half part and a hollow lower half part accompanied by a periodic mesh structure, and has high bonding strength with bone, high occlusion end strength and high shear resistance.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a zirconia ceramic implant with a periodic pore structure and a preparation method. Background technique [0002] In recent years, with the widespread use of zirconia materials in the field of biomedicine, it is a trend to use zirconia as a medium to restore missing teeth. Zirconia is a high-molecular biologically inert ceramic material, which not only has good biocompatibility, can maintain a long-term stable state, but also has clinically acceptable mechanical properties. [0003] The zirconia ceramic implant in the prior art is a solid body with a single upper and lower parts. In order to ensure the fusion of the implant and bone tissue, it takes longer to fix the implant with bone tissue, which increases the restoration cycle of the implant and increases the number of zirconia ceramic implants. The amount of material used increases production costs. Contents of the invent...
