[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The tooth retainer shown includes a tooth retainer body 1. The tooth retainer body 1 has a first cavity inside for placing the tooth surface after orthodontic treatment. The tooth retainer body 1 includes a base layer 101. The base layer 101 has a reinforcing layer 102 inside. The side of the base layer 101 away from the reinforcing layer 102 and the side inside the reinforcing layer 102 are both coated with a wear-resistant layer 103. The wear-resistant layer 103 located on the side inside the reinforcing layer 102 is coated with an oil-resistant layer 104. The oil-resistant layer 104 has an antibacterial layer 105 on the side away from the wear-resistant layer 103.

[0026] like Figures 1-5 As shown, the substrate layer 101 is made of silicone rubber material. The silicone rubber material in this utility model is a transparent material. The tooth orthodontic retainer body 1 is made of transparent elastic material, which makes it easy to observe the condition of the teeth and improves the aesthetics.

[0027] like Figures 1-5 As shown, the reinforcing layer 102 is made of nano-amorphous diamond film. The nano-amorphous diamond film in this invention has excellent properties of high transparency and high hardness. By setting the reinforcing layer 102, the hardness of the orthodontic retainer body 1 can be improved, the service life of the orthodontic retainer body 1 can be extended, and the surface smoothness of the orthodontic retainer body 1 can also be effectively increased, making it easier to clean.

[0028] like Figures 1-5 As shown, the wear-resistant layer 103 is a wear-resistant coating formed by applying silicone-feel coating to the substrate layer 101 and the reinforcing layer 102. In this invention, organosilicon resin is used as the main resin of the silicone-feel coating, which makes the surface of the orthodontic retainer body 1 softer and more elastic, and can improve the wear resistance of the orthodontic retainer body 1. By setting the wear-resistant layer 103, the wear resistance of the orthodontic retainer body 1 can be increased, preventing teeth from damaging the orthodontic retainer body 1 and extending the service life of the orthodontic retainer body 1.

[0029] like Figures 1-5 As shown, the anti-oil layer 104 is an anti-oil coating formed by applying a superhydrophobic and oleophobic fluorocarbon coating onto the wear-resistant layer 103. The superhydrophobic and oleophobic fluorocarbon coating in this invention typically has a micro-nano composite structure. This structure can further reduce surface energy and improve oleophobic performance. The micro-nano roughness of the surface of the superhydrophobic and oleophobic fluorocarbon coating can make oil droplets form spherical shapes on the surface, reducing the contact between oil droplets and the surface of the orthodontic retainer body 1, thereby enhancing the oleophobic effect. It has superhydrophobic and oleophobic properties. By setting the anti-oil layer 104, oil stains can be prevented from adhering to the inside of the orthodontic retainer body 1, making it easier to clean the orthodontic retainer body 1 and improving the cleanliness of the inside of the orthodontic retainer body 1.

[0030] like Figures 1-5 As shown, the antibacterial layer 105 is made of nano zinc oxide particles. The nano zinc oxide particles in this invention have antibacterial, anti-inflammatory and antifungal properties. The nano zinc oxide particles can directly contact bacteria, destroy the bacterial cell membrane and cell wall, causing bacterial death, and can effectively inhibit bacterial growth. By setting the antibacterial layer 105, this invention can inhibit the growth and reproduction of bacteria on the tooth surface and effectively inhibit pathogenic bacteria on the tooth surface.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
