Abstract

The invention relates to an artificial tooth root with a synergistic antibacterial coating and a preparation method of the artificial tooth root. The artificial tooth root with the synergistic antibacterial coating is composed of a titanium or titanium alloy artificial tooth root matrix and a lamination nanostructure TiO2 coating loaded with silver nanoparticles (AgNPs) and graphite like carbon nitride (g-C3N4) on the surface. The preparation method includes the steps that firstly, rod-shaped nanostructure sodium titanate is prepared on the surface of titanium or a titanium alloy by a hydrothermal synthesis technology; secondly, the AgNPs is loaded on the surface of the rod-shaped nanostructure sodium titanate by an ion exchange technology and an ultraviolet light reduction method; thirdly, the silver loaded sodium titanate is transformed into the TiO2 bioactive coating loaded with the AgNPs on the surface by a high-temperature annealing process; and finally, a chemical vapor deposition technology is used for depositing g-C3N4, and the surface of the TiO2 bioactive coating is transformed into lamination nanostructure TiO2 coating with g-C3N4 / Ag, therefore, the artificial tooth rootwith the synergistic antibacterial coating is obtained.

Description

technical field [0001] The invention relates to an artificial tooth root with a synergistic antibacterial coating and a preparation method thereof, in particular to an artificial tooth root which uses titanium or titanium alloy as a processing substrate and adopts hydrothermal synthesis method, ion exchange technology, ultraviolet light reduction method and high temperature annealing. And the g-C obtained by chemical vapor deposition technology on its surface 3 N 4 / Ag-TiO 2 coating. The coating has a slow-release silver ion antibacterial function, and g-C 3 N 4 , Ag, TiO 2 It can act synergistically under the action of a light source, play the role of assisting photocatalysis and enhancing antibacterial, and belongs to the technical field of dental implant materials. Background technique [0002] Dental implants are the first choice to restore missing teeth, and their functions, shapes, and utility are similar to real teeth. The artificial tooth root of titanium or t...
