Surface treatment method of zirconia implant

Abstract

The invention discloses a surface treatment method of a zirconia implant, and belongs to the technical field of implant processing for anodontia repair. Before dewaxing of a zirconia implant blank formed through injection, the surface of the zirconia implant blank formed through injection is subjected to shot blasting treatment; then, dewaxing is performed; next, sintering is performed; finally, acid corrosion treatment or surface treatment in other modes is performed. The surface treatment method of the zirconia implant has a good shot blasting pit hitting effect. The treatment method has the advantages that the shot blasting treatment is performed in the blank state before the dewaxing of the zirconia implant blank formed through injection (because obvious concave-convex pits can be hit through shot blasting in the blank in the state), so that the surface of the zirconia implant blank formed through injection generates concave-convex pits; then, dewaxing and sintering are performed; the final sintering formed zirconia implant surface has the obvious concave-convex pits; finally, the acid corrosion or surface treatment in other modes is performed.

Description

technical field [0001] The invention discloses a surface treatment method for a zirconia implant, which belongs to the technical field of implant processing for restoring missing teeth. Background technique [0002] In the use of implants, special attention should be paid to the combination of implants and gum bone. In the early stage of implantation, the osseointegration process between the gum bone and the implant should be short and the osseointegration should be stable and firm. During the use process after implantation, it is required that the implant should be stable in the gum bone for a long time, that is to say, the osseointegration between the implant and the gum bone should be stable for a long time. [0003] In the prior art, the most common ones are implants made of pure titanium or medical titanium alloy. Among the surface treatment methods of pure titanium implants, the most common method is shot peening acid corrosion treatment, which is to make the i...

AI Technical Summary

Problems solved by technology

The sand blasting and sand blasting and acid etching methods have a problem in the processing process. After the zirconia implant is sintered, it becomes a hard and stable zirconia ceramic crystal, resulting in poor shot peening effect, because the shot peened itself It is zirconium beads. Use zirconium beads to spray zirconia ceramic products, and there will be no obvious concave-convex pits.
