Description

Technical Field

[0001] The utility model relates to the technical field of dentures, in particular to a denture bracket with antibacterial function. Background Art

[0002] When wearing a complete denture bracket, bacteria are likely to breed on its surface, causing various oral diseases. In the prior art, antibacterial components are added to the bracket material to endow the denture bracket with antibacterial properties. For example, patent CN109172383A adopts the method of adding nano silver powder to the bracket material, and patent CN110384616B adds silver-loaded silica and natural antibacterial agents. Although these two technologies can endow the denture bracket with antibacterial properties, the following technical problems exist in their use:

[0003] First, substances with antibacterial properties are wrapped in the bracket material, and there are fewer effective antibacterial components in contact with bacteria. Therefore, the antibacterial properties of these antibacterial substances cannot be fully utilized, resulting in weak antibacterial properties of the denture products.

[0004] Second, in the above technologies, the main component material of the denture bracket is denture powder, which belongs to resin. Such denture brackets have poor mechanical properties, are prone to cracking, and have a short service life. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and deficiencies, and provide a denture bracket with antibacterial function. The denture bracket has antibacterial properties by covering a silver metal antibacterial layer on the surface of the metal bracket. Since the antibacterial substance can directly contact bacteria, it has very good antibacterial properties; and the metal bracket has very good mechanical properties, which can greatly improve the service life of the denture products; by slightly increasing the roughness of the inner surface of the metal bracket, a greater adsorption force can be formed between the metal bracket and the human oral mucosa, making the denture wear more firmly.

[0006] The technical solution of the utility model is realized as follows: A denture bracket with antibacterial function, including a metal bracket and a rubber bracket arranged on the side of the metal bracket, characterized in that: the surface of the metal bracket is covered with a silver metal antibacterial layer, and the thickness of the silver metal antibacterial layer is 1-50 microns; the roughness of the inner surface of the metal bracket is ≤0.2 microns.

[0007] Furthermore, the metal bracket is composed of a connecting part and an embedding part with an integral structure, and the rubber bracket is coated on the embedding part.

[0008] Furthermore, a number of embedding holes are provided on the embedding part.

[0009] Further, a tab is provided at the outer edge of the splicing hole, and the height of the tab is 0.1 - 0.5 mm.

[0010] Furthermore, a silver metal antibacterial layer is coated on the surface of the connecting portion.

[0011] Even further, the roughness of the inner surface of the rubber base is ≤ 0.2 microns.

[0012] Advantages of the present utility model:

[0013] First, the surface of the metal bracket is coated with a silver metal antibacterial layer. In this way, the silver metal antibacterial layer directly combines with bacteria, thereby being able to kill or inhibit the growth of bacteria, making the denture product have good antibacterial properties. The validity period of the silver metal antibacterial layer is directly related to its thickness. In this application, the preferred thickness is 1 - 50 microns, so that an appropriate thickness can be selected according to the patient's age and economic ability to ensure that the denture product maintains good antibacterial properties within its service life. In addition, the metal bracket has good durability and stability. In this application, the metal bracket is combined with the rubber base, which can improve the overall mechanical properties of the denture product, prevent it from cracking, and thus greatly improve its service life.

[0014] Second, compared with the requirement in the prior art that the surface roughness of the metal bracket is less than 0.025 microns, since the metal bracket in this application is coated with a silver metal antibacterial layer, which can inhibit or kill bacteria in the oral cavity, even if the surface roughness of the metal bracket is increased to 0.2 microns, it can effectively prevent bacteria from adhering to the metal bracket. And the surface of this slightly rough metal bracket can form a larger contact surface with the oral mucosa, enhancing the adsorption force between the two, thereby installing the denture more firmly in the user's oral cavity, helping the user restore the chewing function to a greater extent, and providing a better user experience for the user. At the same time, it also helps to reduce the processing difficulty of polishing the metal bracket. Description of the Drawings

[0018] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model.

[0019] AsFigure 1 , 2 As shown in Figure 3, the present utility model provides a denture bracket with antibacterial function, including a metal bracket 1 and a rubber base 2 arranged on the side of the metal bracket 1. To achieve the purpose proposed by the present utility model, the surface of the metal bracket 1 is coated with a silver metal antibacterial layer 3, and the thickness of the silver metal antibacterial layer 3 is 1 - 50 microns; the surface roughness of the inner surface of the metal bracket 1 is ≤ 0.2 microns; the material of the metal bracket 1 can be selected from materials such as pure titanium, titanium alloy, cobalt-chromium alloy, etc.; because the surface of the metal bracket 1 is coated with the silver metal antibacterial layer 3, which can effectively kill bacteria in the oral cavity, even if the requirement for the surface roughness of the metal bracket 1 of the present utility model is appropriately reduced, the number of bacteria attached to the surface of the metal bracket 1 can be effectively controlled, thereby maintaining the cleanliness and hygiene of the oral cavity; and when the inner surface of the metal bracket 1 contacts the oral mucosa of the human upper jaw, a larger contact area can be formed, so as to fit more closely with the oral mucosa, making the denture not fall off easily, and helping the user recover the chewing function to a greater extent, thus bringing a better use experience to the user; the silver metal antibacterial layer 3 can be a silver metal coating or a silver ion antibacterial coating, and both have their own advantages and disadvantages; the silver metal coating has the advantages of mature processing technology, low processing cost, and high coating firmness, and can be processed by mature methods such as electroless plating, electroplating, vacuum electroplating, etc.; while the antibacterial effect of the silver ion antibacterial coating is better, but its processing process is relatively complex and the processing cost is higher, and customers can choose the product suitable for themselves according to their actual situation.

[0020] As Figure 1 , 2 shown, the metal bracket 1 is composed of a connecting part 11 and an embedding part 12 of an integral structure, and the rubber base 2 is coated on the embedding part 12, so that the metal bracket 1 and the rubber base 2 form an integral structure, greatly improving the mechanical strength of the denture rubber base part, and improving its anti-drop property and service life.

[0021] As Figure 2 , 3 shown, a number of embedding holes 13 are provided on the embedding part 12; in this way, during production, the material of the rubber base 2 passes through these embedding holes 13, so that the embedding part 12 and the rubber base 2 form an integral structure, and the connection between the two is more firm, and the embedding part 12 also provides better support and anti-cracking performance for the rubber base 2.

[0022] To further enhance the connection strength between the embedding part 12 and the rubber base 2, as Figure 2 , 3 shown, convex pieces 14 are also provided at the outer edge of the embedding holes 13, and the height of the convex pieces 14 is 0.1 - 0.5 mm; through these convex pieces 14, the biting area between the embedding part 12 and the rubber base 2 can be further increased, making the combination of the two more firm.

[0023] As Figure 3 shown, the surface of the connecting part 11 is covered with a silver antibacterial layer 3; since the embedding part 12 is buried in the rubber base 2, only the connecting part 11 contacts the inner part of the human oral cavity, so that both the manufacturing cost can be saved and the antibacterial performance of the product can be ensured. During manufacturing, the connecting part 11 and the embedding part 12 can be manufactured separately. After the surface of the connecting part 11 is covered with the silver ion antibacterial layer 3, the connecting part 11 and the embedding part 12 are fixedly connected together to form an integral structure by welding or other technical means, and then the rubber base material is wrapped around the embedding part 12 to form the rubber base 2 part.

[0024] As Figure 3 shown, the roughness of the inner surface of the rubber base 2 is ≤0.2 microns. In this way, after the rubber base 2 is sleeved on the alveolar ridge, a strong adsorption force can also be formed between the rubber base 2 and the mucosa of the alveolar ridge, further enhancing the firmness of the denture product during wearing, thereby further improving the chewing function of the denture; and the roughness of ≤0.2 microns can also effectively prevent bacteria from adhering to the rubber base 2, which helps to maintain the cleanliness of the oral cavity.
