Background
The polytetrafluoroethylene is a high molecular compound containing fluorine atoms in the molecular main chain, F atoms in PTFE molecules cover C-C bonds, and the C-F bonds have high energy and good chemical stability; since the sixties of the last century, polytetrafluoroethylene has been widely used in the fields of industry, medical treatment, military and the like because of its stable physicochemical properties and good biocompatibility.
The silicone rubber is straight-chain polyorganosiloxane with high molecular weight, the main chain is composed of silicon and oxygen atoms alternately, and the unique chemical structure determines that the silicone rubber has good physiological inertia and body fluid corrosion resistance, ageing resistance under severe environmental conditions, excellent biocompatibility, extremely small reaction on human tissues, no foreign body reaction in vivo, no inflammation on surrounding tissues and the like;
the expanded polytetrafluoroethylene has a special stretching process in the production process, generates a large number of node and fiber structures to form micropores, and endows the expanded polytetrafluoroethylene with special properties due to the special micropore structures.
In the clinical application of nose bridge reshaping, a nose bridge prosthesis made of a silicon rubber material has a smooth surface, so that tissues cannot be better combined with the prosthesis after implantation, and the prosthesis can shift, transmit light and the like; the surface of the prosthesis made of the expanded polytetrafluoroethylene material is provided with micropores, tissues can grow into the micropores and can be better combined with the tissues, the prosthesis can not shift after operation, the effect is more natural, but the prosthesis made of the expanded polytetrafluoroethylene material cannot provide support at the position of the columella nasi due to the fact that the expanded polytetrafluoroethylene material is relatively soft.
