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. The zirconia ceramic implant includes an upper half and a lower half, and the raw materials of the upper half include zirconia, alumina, yttrium trioxide, silicon dioxide, titanium dioxide, polyethylacryloyl, trimethylolpropane three Acrylic, dimethylolpropionic acid, epoxy resin; raw materials in the lower part include zirconia, alumina, silica, titanium dioxide, hydroxyapatite, sodium silicate, polyethylacryloyl, trimethylol Propane Triacrylate, Dimethylolpropionic Acid, Epoxy Resin. The preparation method includes mixing of ceramic matrix powder, premixing of auxiliary agents, preparation of raw materials for the upper half, preparation of raw materials for the lower half, printing of the lower half of the implant, printing of the upper half of the implant and sintering of the ceramic implant. The zirconia ceramic implant has a solid upper part and a hollow lower part with a periodic mesh structure, which has high bone bonding strength, high occlusal end strength, and high shear resistance.

Description

Technical field [0001] The present invention belongs to the field of ceramic technology, specifically relates to a periodic pore structure of zirconia ceramic implants and preparation methods. Background [0002] In recent years, with the widespread use of zirconia materials in the biomedical field, it is a trend to use zirconia as a medium to repair missing teeth. Zirconia is a polymer biologically inert ceramic material that has good biocompatibility, can maintain a long-term stable state, and has clinically acceptable mechanical properties. [0003] Prior art Zirconia ceramic implants for the upper and lower single solid body, in order to ensure the integration of implants and bone tissue, bone tissue fixed implants take longer, increasing the implant restoration cycle, while increasing the use of zirconia ceramic materials, increase production costs. Contents of the Invention [0004] The technical problem to be solved in the present invention is: In view of the above defec...
