[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0024] The present application provides a 3D printed zirconia orthodontic bonding base, which is mainly used to solve the following problems: orthodontic bands are a kind of retention device for fixed orthodontic appliances. Molars are usually selected as the retention teeth for bonding bands. The bands are made by metal forging and molding. However, this material and manufacturing method bring a series of problems: 1. Before installing the bands, the teeth need to be prepared, which may damage the enamel and dentin, affecting the health and function of the teeth; 2. The metal bands affect the appearance of the patients, which is a big challenge for patients who pursue beauty; 3. Due to the large contact area between the bands and the tooth surface, food residues are easily trapped, increasing the difficulty of oral hygiene maintenance; 4. The bonding between the traditional bands and teeth may not be strong enough, affecting the correction effect and treatment time. The following technical solutions are provided, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0025] A 3D printed zirconia orthodontic bonding base mainly includes a substrate body 1, which is "U"-shaped and coated on the outer surface of the tooth. Two left-right distributed repair plate bodies 2 are arranged on the substrate body 1. The lower end surface of the repair plate body 2 is an inwardly concave curved surface to achieve fitting with the tooth. The inner side surface of the substrate body 1 is bonded and fixed to the tooth by a dental adhesive to enhance the bonding strength with the tooth. The "U"-shaped substrate body 1 can achieve precise fitting with the tooth surface. The two repair plate bodies 2 can not only perform morphological repair on tooth caries and defects, but also play a role in increasing the bonding and retention of the substrate body 1 and the tooth.

[0026] For further information, see Figure 2 and Figure 4 The inner side of the substrate body 1 is configured with a plurality of grooves 11, and the interior of the grooves 11 is used to fill the dental adhesive. In specific operation and use: before bonding, the surface of the patient's teeth is cleaned and properly treated to improve the bonding effect of the adhesive, and then the dental adhesive is evenly filled into the grooves 11 on the inner side of the substrate body 1, and then the substrate body 1 filled with the adhesive is accurately placed at the predetermined position of the patient's teeth, and appropriate pressure is applied to ensure that the substrate body 1 is tightly fitted to the tooth surface, and then light curing or chemical curing is performed according to the type of dental adhesive used to ensure that the adhesive is fully hardened to form a stable bond, and finally after the bonding is completed, the bonding condition of the substrate body 1 and the teeth is checked to ensure that there are no gaps or insufficient adhesive, and the dental adhesive filled in the groove 11 forms a stable bonding layer after curing, reducing the risk of affecting the correction effect due to weak bonding;

[0027] It should be particularly noted that the groove 11 is at the micron level. The micron-level groove 11 can provide better bonding retention and stabilization for the bonding substrate body 1, thereby obtaining a good retention effect, effectively transmitting the correction force, more accurately pulling and moving the position of the teeth, and being more convenient for clinical use, making the patient more comfortable and the doctor's treatment more efficient. The design of the micron-level groove 11 significantly increases the contact area between the substrate body 1 and the teeth, thereby improving the firmness of the bonding, helping to distribute the correction force more evenly, reducing local pressure on the teeth, and reducing the possibility of tooth damage. The design of the micron-level groove 11 helps to reduce the gap between the substrate body 1 and the teeth, improving the comfort of the patient wearing the braces, and at the same time, it is not easy to get food stuck and is easy to clean.

[0028] For further information, see Figure 3 A traction cylinder 12 is fixed to the outer side of the substrate body 1, and the two ends of the traction cylinder 12 are connected to facilitate the insertion of correction elements such as arch wires; a traction hook 13 is fixed to the outer side of the traction cylinder 12 for fixing and guiding the correction arch wire to achieve the traction and movement of the teeth. The design of the traction cylinder 12 and the traction hook 13 allows precise control of the application of correction force and improves the accuracy of tooth movement.

[0029] In this embodiment, the substrate body 1, the repair plate body 2, the traction tube 12 and the traction hook 13 are integrally formed by 3D printing; the substrate body 1, the repair plate body 2, the traction tube 12 and the traction hook 13 are all made of zirconia. In the specific implementation, computer-aided design software is used to design the three-dimensional structure of the substrate body 1, the repair plate body 2, the traction tube 12 and the traction hook 13 according to the patient's tooth model and orthodontic needs, ensuring that all components are designed with mutual integration and coordination in mind, so as to facilitate integral forming during 3D printing. Then, zirconia is selected as the printing material because it has high biocompatibility, high strength and aesthetics, and is suitable for dental orthodontic applications. Secondly, 3D printing technology is used to print the zirconia material layer by layer according to the model designed by the computer-aided design software to form an integrated substrate body 1, the repair plate body 2, the traction tube 12 and the traction hook 13. Finally, after printing is completed, necessary post-processing is performed, including grinding, polishing and disinfection, to ensure that the product surface is smooth and suitable for clinical use.

[0030] The benefits of using 3D printing as one-piece molding for the device and the benefits of using zirconia as the printing material are: 3D printing technology allows precise orthodontic components to be customized for each patient, improving the personalization and effectiveness of treatment; one-piece molding reduces the need for traditional multi-component assembly, reducing production costs and time; the high-strength characteristics of zirconia make the components more durable and reduce the risk of damage during treatment; the precise matching and micron-level design of the substrate body 1 improve the bonding effect with the teeth and ensure stability; the natural color and smooth surface of the zirconia material enhance the aesthetics of the appliance and improve the patient's wearing experience; due to the precise design and smooth surface of the components, the accumulation of food residues is reduced, making it easier for patients to maintain oral hygiene; the integrated design reduces the complexity of clinical operations and speeds up the treatment process; due to the precise design and smooth surface of the components, the friction and irritation to the oral soft tissues are reduced, improving the comfort of the patients; the durable zirconia material reduces the subsequent maintenance and replacement required due to component damage or wear.
