Abstract

The invention relates to a dental implant and a preparation method thereof. The dental implant comprises an implant body and a graphene layer, wherein the surface of the implant body is coated with the graphene layer, and the graphene layer is a reduced graphene layer; the dental implant is obtained by dropwise adding a graphene oxide solution onto the surface of a three-dimensional (3D) printing implant body, carrying out spin-coating so as to enable the graphene oxide solution to be evenly distributed, naturally drying the implant body, and then carrying out high temperature reduction treatment on the dried implant body. Compared with the prior art, the method adopts a spin-coating technology to enable the surface of the implant body to be coated with oxidized form graphene, and enables the oxidized form graphene to be reduced by using a high temperature reduction method so as to obtain a reduced graphene coating, so that the coating on the surface of the implant body is firm, does not easily fall off and is higher in mechanical strength; the dental implant has good biological activity and can obtain a good osseointegration effect.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a dental implant and a preparation method thereof. Background technique [0002] Dental implants are called the "third tooth" of human beings. They can not only repair missing teeth, but also solve the problem of damage to natural teeth caused by conventional denture restorations. Since Branemark proposed the concept of osseointegration in the 1960s, osseointegration has become the theoretical basis of modern dental implant restoration and the gold standard for successful dental implant restoration. Titanium alloy Ti-6Al-4V is currently internationally recognized as an implant material with a high safety factor, and it is also the main alloy material for implants. The surface properties of implants have an important impact on their osseointegration, mainly including surface topography, surface elements and their wettability. Therefore, it is very important to obtain a good implan...
