[0019] The following description is used to disclose the present application so that those skilled in the art can implement the present application. The preferred embodiments in the following description are only used as examples, and other obvious modifications can be thought of by those skilled in the art. The basic principles of the present application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0020] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, the above terms cannot be understood as a limitation of the present application.

[0021] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0022] Reference Figs. 1 to 3 The embodiments of the present application provide a child orthodontic appliance, which is composed of an upper jaw appliance 10 and a lower jaw appliance 20 cooperating with each other and having a connection relationship, and is respectively worn on the upper jaw teeth of a child and the lower jaw teeth of a child in a paired manner, wherein the upper jaw appliance 10 and the lower jaw appliance 20 can be connected through opposite two ends, or can be connected through two ends and any point or multiple points between the two ends, in addition, the upper jaw appliance 10 and the lower jaw appliance 20 respectively have shapes matched with the upper jaw teeth and the lower jaw teeth of a child, and the upper jaw appliance 10 and the lower jaw appliance 20 are respectively provided with tooth sockets matched with the upper jaw teeth and the lower jaw teeth of a child to cover the entire upper and lower teeth, respectively, forming an upper jaw sleeve type structure and a lower jaw sleeve type structure, in addition, the upper jaw appliance 10 and the lower jaw appliance 20 are both three-layer structures, including soft layers 11 close to and away from the tooth surface and a hard layer 12 between the two soft layers 11.

[0023] Generally, the maxillary appliance 10 and mandibular appliance 20 can be made by thermoforming children's dental molds. Through the three-layer structure of soft layer-hard layer-soft layer, it can be customized for different children's dental conditions, increasing adaptability to children's teeth, achieving precise treatment, and is not easy to fall off after wearing, resulting in high child compliance. Since the soft layer is in contact with children's teeth, it has good wearing comfort. At the same time, since the core layer is made of hard layer and the skin layer is made of soft layer, it can provide continuous orthodontic force while improving wearing comfort, achieving durable orthodontic treatment.

[0024] During the manufacturing process of maxillary appliance 10 and mandibular appliance 20, each appliance is custom-made. Doctors can provide clinical models, CT data and clinical plans, etc. Technicians make 3D dental models according to the treatment plan, and then put the dental models into thermoforming equipment for manufacturing.

[0025] In the connection between the maxillary appliance 10 and the mandibular appliance 20, the two ends of the contact surface of the maxillary and mandibular appliances can be welded, or the two ends and any one or more points between the two ends can be welded, by ultrasonic welding, high-frequency welding or other welding techniques.

[0026] Whether it is the maxillary appliance 10 or the mandibular appliance 20, welding at both ends, or welding at either end or at any point or multiple points between the two ends, will help to ensure a firm connection, accurate positioning, and convenient use of the maxillary and mandibular appliances.

[0027] In one embodiment, both the maxillary appliance 10 and the mandibular appliance 20 are three-layer membrane structures, wherein the soft layer 11 is a soft membrane layer and the hard layer 12 is a hard membrane layer, which can be formed by hot pressing and multi-layer co-extrusion. Hot pressing involves extruding the hard layer 12 and the soft layer 11 separately, and then combining the soft layer and the hard layer into a three-layer membrane structure by a hot press or pressure roller. Co-extrusion involves passing the soft layer 11 and the hard layer 12 material particles through different extruders, extruding them through a multi-layer mold, and then cooling and drawing them to obtain a three-layer membrane structure.

[0028] The soft layer 11 has a hardness of 60A to 55D and is usually made of one or more thermoplastic polyurethanes or thermoplastic elastomers. The hard layer 12 has a hardness of 55D to 95D and is usually made of one or more polyethylene terephthalate-ethylene glycol copolyesters, nylon, thermoplastic polyurethanes, or thermoplastic elastomers.

[0029] More preferably, the thicknesses of the two soft layers 11 are equal or unequal, and the thicknesses of the soft layer 11 and the hard layer 12 are equal or unequal.

[0030] In one embodiment, the outer surfaces and inner surfaces near the alveolar bone of the maxillary appliance 10 and the mandibular appliance 20 are either smooth or matte. That is, the outer and inner surfaces of the maxillary appliance 10 are either smooth or matte, and the outer and inner surfaces of the mandibular appliance 20 are either smooth or matte. More specifically, when the outer and inner surfaces of the maxillary appliance 10 are smooth, the outer and inner surfaces of the mandibular appliance 20 can be either smooth or matte. Similarly, when the outer and inner surfaces of the maxillary appliance 10 are matte, the outer and inner surfaces of the mandibular appliance 20 can also be either smooth or matte. In other words, there is no direct relationship between the maxillary appliance 10 and the mandibular appliance 20.

[0031] In one embodiment, the outer surface of the maxillary appliance 10 is smooth and the inner surface of the maxillary appliance 10 is matte; or, the outer surface of the maxillary appliance 10 is matte and the inner surface of the maxillary appliance 10 is smooth.

[0032] In another embodiment, the outer surface of the mandibular appliance 20 is smooth and the inner surface of the mandibular appliance 20 is matte; or, the outer surface of the mandibular appliance 20 is matte and the inner surface of the mandibular appliance 20 is smooth.

[0033] Whether it's the maxillary appliance 10 or the mandibular appliance 20, when the inner and outer surfaces are inconsistent, it can prevent reflection, and at the same time, the diaphragm is more aesthetically pleasing and easier to use.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
