Embodiment 1

[0015] (1) The surface of the pure titanium dental implant is sandblasted with large particles of 0.25mm corundum at a pressure of 4bar, then ultrasonically cleaned in acetone, ethanol, and distilled water, and dried to provide a suitable morphology basis for the next step of double pickling;

[0016] (2) Put the sandblasted pure titanium dental implant into a mixed acid solution of 30% sulfuric acid and 10% hydrochloric acid, heat it to 60°C, treat it for 8 minutes, take out the distilled water and rinse;

[0017] (3) Put the pure titanium dental implant into the mixed acid solution of 30% sulfuric acid and 10% hydrochloric acid again, heat it to 60°C, treat it for 10 minutes, take out the distilled water, wash it, and dry it to obtain a biologically active porous structure.

Abstract

The invention discloses a method for preparing a porous structure on the surface of a pure titanium dental implant, which comprises the following steps of sand blasting on the surface of the pure titanium dental implant and double acid treatment so that a layer of multistage porous structure is formed on the surface of the pure titanium dental implant. By using the method, the porous structure prepared on the surface of the pure titanium dental implant has good bone tissue compatibility, and the combination intensity of the dental implant and bone tissue can be improved, so that long-term clinical success rate of the dental implant is improved, and the method has the characteristics of being simple in technology, easy in equipment machining, and capable of reducing the cost greatly.

Description

technical field [0001] The invention relates to a bioactive artificial tooth implant, in particular to a method for preparing a porous structure on the surface of a pure titanium dental implant. It belongs to the technical field of A61C8 / 00(2006.01)I in the International Patent Classification. Background technique [0002] The existence of the porous structure of dental implant biomaterials used in clinic can improve the interface effect between the implant material and the host bone. If the soft and hard tissues near the interface can grow into the pores, the fibrous tissue and new bone tissue form an intertwined state. In this way, it can not only promote the normal metabolism of the interface, but also greatly improve the bonding strength between the scaffold material and bone tissue. Studies have shown that when the pore size of the porous implant material is 15-40 μm, fibrous tissue can grow into the implant; when the pore size is 40-100 μm, non-mineral bone samples c...
