preparation example Construction

[0029] In another typical embodiment of the present application, a method for preparing an antibacterial dental implant is provided, the preparation method comprising: step S1, performing micro-arc oxidation on the dental implant body to growing a micro-arc oxidation film layer; step S2, performing plasma immersion ion implantation on the dental implant body that has undergone micro-arc oxidation, so as to load nanometer antibacterial functional materials on the micro-arc oxidation film layer.

[0030]The micro-arc oxidation film layer is grown in situ on the dental implant body by the micro-arc oxidation technology, and the fitting degree of the micro-arc oxidation film layer and the dental implant body is high and relatively firm; and the surface pore structure of the dental implant body is made It is richer, and there are many crater-like pore structures in it, so it can not only increase the surface roughness of the dental implant body, but also greatly improve the surface ...

Embodiment 1

[0042] Dental implant body: Medical pure titanium prepared by forging technology is selected as the dental implant body.

[0043] Sandblasting treatment: The dental implant body is subjected to strong sandblasting treatment, the abrasive is SiC, the particle size of the abrasive is 150μm, the sandblasting distance is 12cm, the compressed air pressure is 8bar, and the injection time is 30s. The surface obtained after sandblasting Morphology, observed by scanning electron microscope, the appearance is as follows figure 1 shown. The body of the dental implant after sandblasting was thoroughly ultrasonically cleaned with acetone and deionized water for 20 minutes in sequence, and dried for later use.

[0044] Micro-arc oxidation electrolyte preparation: Dissolve calcium acetate and sodium dihydrogen phosphate in deionized water, mix the reagents evenly, and prepare an electrolyte, in which the concentration of calcium acetate is 0.01mol / L, and the concentration of sodium dihydrog...

Embodiment 2

[0048] Preparation of the dental implant body: the Ti-6Al-4V dental implant body was manufactured by additive manufacturing electron beam melting technology.

[0049] Sandblasting treatment: The dental implant body is subjected to strong sandblasting treatment, the abrasive is SiC, the particle size of the abrasive is 300 μm, the sandblasting distance is 12cm, the compressed air pressure is 8bar, and the injection time is 30s. The body of the dental implant after sandblasting was thoroughly ultrasonically cleaned with acetone and deionized water for 20 minutes in sequence, and dried for later use.

Abstract

The invention provides an antibacterial tooth implant and a preparation method of the antibacterial tooth implant. The antibacterial tooth implant comprises a tooth implant body, a micro-arc oxidationfilm layer and a nano-antibacterial function material, wherein the micro-arc oxidation film layer is arranged on the surface of the tooth implant body; the nano-antibacterial function material is loaded to the micro-arc oxidation film layer. According to the technical scheme, the micro-arc oxidation film layer is arranged on the tooth implant body, so that the surface pore structure of the toothimplant body is rich, many pore structures similar to volcanic vents exist, therefore, the surface roughness of the tooth implant body can be increased, the surface porosity is alos greatly improved,at the time, the antibacterial function material of the nano size adopting the plasma immersed ion injection method can be injected to the surface of the micro-arc oxidation film layer and also can beinjected into the pore structures of the micro-arc oxidation film layer, so that the loading amount of the nano-antibacterial function material is greatly increased, meanwhile, when bacteria enter the micropores, sterilizing can be carried out in time, so that the permanent antibacterial effect is achieved.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to an antibacterial dental implant and a preparation method thereof. Background technique [0002] Teeth are highly calcified tissues with a certain shape in the human oral cavity, which have the functions of chewing, helping pronunciation and maintaining the appearance of the face. At present, the number of defective or missing teeth caused by caries, periodontal disease, trauma and other reasons in my country is more than 1 billion. Defects of teeth, jaws, and temporomandibular joints will cause physiological dysfunction of patients, affect the appearance, and May cause psychological disturbance. [0003] Dental implants, as a restoration method that is very similar to natural teeth in function, structure and aesthetics, have become the first choice in stomatology to solve the problem of patients with missing teeth. The market demand is large. At present, 15 million dental implants ...
