[0037] figure 1 A process flow diagram showing a method for preparing a zirconia implant bio-coating according to an embodiment of the present application. Such as figure 1 As shown, the method includes: step S100, using a sandblasting machine to perform sandblasting and roughening treatment on the surface of the pretreated zirconia implant to obtain a rough surfaced zirconia implant. Then, through step S200, place the rough-surfaced zirconia implant in a micron-sized zirconia suspension, soak it for a first preset time, take it out, and then sinter it in a sintering furnace to obtain a zirconia implant with a concave-convex porous structure on the surface. Zirconium implants. Then, through step S300, the zirconia particles are sprayed onto the surface of the zirconia implant with a concave-convex porous structure by using the supersonic plasma spraying method, so as to prepare a bio-coating with a micro-nano structure on the surface of the zirconia implant .

Embodiment 1

[0058] First, the zirconia implants without surface treatment were cleaned and pretreated. The pretreatment process is as follows: first put it into absolute ethanol for ultrasonic cleaning for 20-30s to remove surface oil stains, etc., then put it into deionized water for ultrasonic cleaning for 10-20s, and then put it into a blast drying oven at 50-60°C for 4 hours .

[0059] Then, the dried zirconia implants were roughened by sandblasting. The sand blasting roughening process is as follows: select alumina particles of 10 microns to 200 microns, and set the sand blasting machine under the pressure of 0.7Mpa, blast the nozzle of the vertical sand blasting machine for the zirconia implant, and at the same time spray the zirconia The implant was rotated at a rotation rate of 50° / s, the distance between the nozzle and the zirconia implant was 2 cm, and the nozzle was perpendicular to the implant and sprayed uniformly for 40 s.

[0060] At the same time, the zirconia suspension...

Abstract

The invention relates to a preparation method of a zirconium oxide implant biological coating. The method comprises the following steps: carrying out sand blasting roughening treatment on the surfaceof a pretreated zirconium oxide implant by adopting a sand blasting machine to obtain a zirconium oxide implant with a rough surface; placing the zirconia implant part with the rough surface in micron-sized zirconia suspension liquid, performing soaking for a first preset time, then taking out the implant, and then placing the zirconia implant in a sintering furnace to be sintered to obtain a zirconia implant with the surface of a concave-convex porous structure; and spraying zirconium dioxide particles to the surface of the zirconium oxide implant with the surface of a concave-convex porous structure through a supersonic plasma spraying method so as to obtain the biological coating with a micro-nano structure. The biological coating prepared by adopting the preparation method is of the micro-nano structure, and the micro-nano structure can effectively promote the attachment growth of bone cells, so that the finally prepared biological coating of the zirconium oxide implant has highermatrix bonding strength, not only has a stable structure, but also has excellent mechanical strength and biocompatibility.

Description

technical field [0001] The disclosure relates to the technical field of dental restoration medical devices, in particular to a method for preparing a zirconia implant biological coating and a zirconia implant. Background technique [0002] Titanium oral implants are the mainstream implants on the market at present, with excellent comprehensive performance. The host immune response, release of metal elements, allergic reaction, and soft tissue coloring caused by titanium metal have gradually become prominent. Therefore, due to its excellent biocompatibility, low plaque adhesion, low allergenicity and ability to effectively reduce platelet aggregation, zirconia implants have excellent fracture strength and bending strength, low thermal conductivity and excellent Its corrosion resistance and hardness, as well as the aesthetic effect similar to natural teeth, are more and more favored by people. However, due to the high chemical inertness of zirconia, it is difficult to obtain...
