Problems solved by technology

The sand blasting and sand blasting and acid etching methods have a problem in the process. After the zirconia implant is sintered, it becomes a hard and stable zirconia ceramic crystal, which makes the shot peening effect poor. It is a zirconium bead itself. If you use zirconium beads to spray zirconia ceramic products, you will not be able to make obvious concave-convex pits.

Embodiment 1

[0029] Such as figure 1 As shown, a method for multiple treatment of the surface of a zirconia implant comprises the following steps:

[0030] 101. Shot peening step: before the formed zirconia implant blank 1 is sintered, the surface of the formed zirconia implant blank 1 is shot blasted so as to form concave-convex pits on the surface of the formed zirconia implant blank 1 ;

[0031] 102. Sintering step: sintering the shot-peened zirconia implant blank 1 to form a zirconia implant 1' with a pit-like structure on the surface;

[0032] 103. Laser treatment step: performing laser irradiation treatment on the surface of the sintered zirconia implant 1'; the laser treatment step can form concave-convex holes and micropores on the surface of the zirconia implant 1';

[0033] 104. Acid etching treatment step: Acid etching treatment is performed on the surface of the zirconia implant 1' after laser treatment. The acid etching treatment will cause micropores on the surface of the z...

Abstract

The invention discloses a zirconium oxide implant surface multiprocessing method, which comprises a shot blasting step; a sintering step; acid corrosion processing step. The method further comprises alaser processing step before the sintering step or after the sintering step, wherein the laser frequency is 20 to 50KHz. According to the zirconium oxide implant surface multiprocessing method disclosed by the invention, firstly, a formed zirconium oxide implant is treated by shot blasting in a formed blank state before being sintered, and convex-concave pits are generated on the surface of the zirconium oxide implant blank; then, the formed zirconium oxide implant is treated by laser; finally, acid corrosion treatment is performed through acid, and following laser treatment and acid corrosion treatment can generate new convex-concave pits on the surface of the zirconium oxide implant, wherein the convex-concave pits include a part of micropores, so that the surface roughness is improved,and bone combination between the zirconium oxide implant and gum bone is more facilitated.

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 implant...
