Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a children's orthodontic appliance. Background Technology

[0002] A dental appliance is a common orthodontic device. It has a regular shape and is placed on the user's teeth to continuously apply force to the teeth in order to correct their shape.

[0003] Traditional orthodontic treatment involves bonding brackets to the tooth surface and then tying archwires into the slots of the brackets. The elastic deformation of the archwire generates corrective force, which is then transmitted to the teeth through the brackets, thus moving the teeth. Typically, the archwire tip is bent back to prevent irritation to the oral cavity. For example, a bracket forceps disclosed in Chinese Patent Publication No. CN221534115U is specifically designed for bending the archwire tip. However, due to the elasticity of the archwire itself and the contact with the peristalsis of the oral muscles, the archwire gradually elongates over time, causing the bent archwire to straighten and the tip to irritate the oral cavity. This is especially problematic for children, who require a lot of communication, as the straightening of the archwire tip during treatment can easily irritate the oral cavity and cause discomfort. Therefore, a new solution is needed to address these issues. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a children's orthodontic appliance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a children's orthodontic appliance, comprising: a bracket body, and an arched limiting piece fitted into one side of the bracket body; a base plate for contacting the tooth surface is fixedly connected to the bottom of the bracket body; a bracket groove for installing the archwire is formed on the bracket body; fitting grooves are formed on both sides of the bracket body for connecting the arched limiting piece; the fitting groove is composed of several arc-shaped grooves arranged continuously along the length direction of the base plate, forming a multi-level limitation that allows the arched limiting piece to move multiple times; a space for archwire deformation is formed between the arched limiting piece and the bracket; as time increases, the arched limiting piece, which resists the archwire that has bent back after installation, can gradually change its position connected to the arc-shaped groove under the resistance and support of the archwire's resilience.

[0006] In a preferred embodiment of this invention, the arched limiting sheet is made of stainless steel that is elastic and corrosion-resistant.

[0007] In a preferred embodiment of this utility model, the arched limiting piece and the bracket body are connected by a snap-fit ​​structure, and the snap-fit ​​cross-section is arc-shaped.

[0008] In a preferred embodiment of this invention, the opening width of the arc-shaped groove is greater than the width of the buckle.

[0009] In a preferred embodiment of the present invention, an adhesive layer is provided on the bottom plate at the bottom of the bracket body, and the adhesive layer is made of a biocompatible adhesive.

[0010] In a preferred embodiment of this utility model, an arc-shaped rail is provided on the outer side of the bracket body for fitting the bow wire after bending.

[0011] In a preferred embodiment of this invention, the surface of the arched limiting sheet is smoothed.

[0012] In a preferred embodiment of this utility model, baffles are provided at both ends of the outermost part of the buckle, and the baffles are used to close the entire fitting groove.

[0013] In a preferred embodiment of this utility model, the arched limiting piece has an arched cross-section in the height direction of the bracket body, and the cross-sectional width in the bottom direction of the bracket body gradually narrows from one side to the other. The narrowest point of the arched limiting piece forms a space with the bracket body that is the same size as the cross-section of the bow wire, which abuts against the bow wire.

[0014] In a preferred embodiment of this utility model, the material of the bracket body is lightweight metal or high-strength plastic.

[0015] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0016] This invention utilizes a multi-level interlocking design between the arched limiting piece and the bracket body, combined with the elasticity of the archwire and the dynamic adjustment of the deformation space, to achieve gradual control of local orthodontic force during children's orthodontic treatment. When the end of the archwire deforms within the bracket groove and forms a backbend, the arched limiting piece, under the elasticity of the archwire, gradually shifts along the interlocking groove, causing the area of ​​orthodontic force application to switch periodically. This allows for precise control of the tooth movement path and the distribution of orthodontic force. Compared to traditional fixed braces, this design solves the problem of oral mucosal irritation caused by excessive elongation of the archwire end. At the same time, through the multi-level displacement and elastic support of the arched limiting piece, a rapid and gradual orthodontic effect can be achieved during orthodontic treatment, simulating the natural process of gradual tooth movement, effectively shortening the treatment period and improving wearing comfort.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] like Figure 1 and Figure 2 As shown, a children's orthodontic appliance includes: a bracket body 1, and an arched limiting piece 4 fitted onto one side of the bracket body 1; a base plate 3 for contacting the tooth surface is fixedly connected to the bottom of the bracket body 1; a bracket groove for installing the archwire 2 is formed on the bracket body 1; fitting grooves 11 are formed on both sides of the bracket body 1 for connecting the arched limiting piece 4; the fitting grooves 11 are composed of several arc-shaped grooves arranged continuously along the length direction of the base plate, forming a multi-level limitation that allows the arched limiting piece 4 to move multiple times; a space is formed between the arched limiting piece 4 and the bracket that allows the archwire 2 to deform, and as time increases, it resists the archwire 2 that has bent back after installation. The arched limiting piece 4 of the archwire 2 can gradually change its position connected to the arc-shaped groove under the elastic resistance and support of the archwire 2. This structural design does not hinder the elastic displacement of the archwire 2 and thus affect the orthodontic treatment. The arched limiting piece 4 can also form a protective cover to prevent the mucosa from being punctured by the oral muscles when chewing and speaking after the archwire 2 has been bent back, which would cause the archwire 2 to straighten back. This protects the oral cavity, especially for children and other people who need to engage in a lot of oral movements such as communication. When installing this utility model, the arched limiting piece is located on the upper part of the maxillary teeth and on the lower part of the mandibular teeth, and the bending direction is changed accordingly.

[0023] Specifically, the arched restraint plate 4 is made of elastic and corrosion-resistant stainless steel to ensure stable support when in contact with the archwire 2 and to prevent corrosion caused by the oral cavity environment.

[0024] Furthermore, the arched limiting piece 4 is connected to the bracket body 1 by a snap-fit ​​structure 41. The snap-fit ​​41 has an arc-shaped cross-section, and the opening width of the arc-shaped groove is greater than the width of the snap-fit ​​41. This structure design not only ensures the stable connection of the arched limiting piece 4, but also significantly reduces the resistance of the elastic limiting piece to the rebound of the bow wire 2, ensuring the correction effect of the bow wire 2.

[0025] Furthermore, an adhesive layer is provided on the bottom plate 3 at the bottom of the bracket body 1. The adhesive layer is made of a biocompatible adhesive to ensure the connection stability between the teeth and the bracket body 1.

[0026] Furthermore, an arc-shaped rail is provided on the outer side of the bracket body 1 to fit the bow wire 2 after bending back, and to limit the connection position between the bow wire 2 and the bracket body 1.

[0027] Furthermore, the surface of the arched restrictor 4 is smoothed to reduce irritation to the oral mucosa and improve patient comfort.

[0028] Furthermore, baffles 42 are provided at the outermost two ends of the buckle 41. The baffles 42 are used to close the entire fitting groove 11 to prevent liquids and food residues in the oral cavity from entering the fitting groove 11 and to ensure smooth movement of the arc-shaped limiting piece.

[0029] Furthermore, the arched limiting piece 4 has an arched cross-section in the height direction of the bracket body 1, and the cross-sectional width gradually narrows from one side to the other in the bottom direction of the bracket body 1. The narrowest part of the arched limiting piece 4 forms a space with the same size as the cross-section of the archwire 2 between itself and the bracket body 1, which abuts against the archwire 2. This ensures that the archwire 2 will not move arbitrarily and affect the orthodontic effect in the initial period after the bracket body 1 is installed on the teeth. At the same time, it provides a space for the archwire 2 to deform for dynamic adjustment.

[0030] Furthermore, the bracket body 1 is made of lightweight metal or high-strength plastic, specifically stainless steel, to reduce the weight of the orthodontic appliance and improve the patient's wearing comfort.

[0031] The children's orthodontic appliance of this utility model achieves gradual control of orthodontic force through the multi-level interlocking design of the arched limiting piece 4 and the bracket body 1, combined with the elasticity of the archwire 2. The arched limiting piece 4 is made of stainless steel, providing stable support and preventing corrosion. It is connected to the bracket body 1 via a snap fastener 41, ensuring a stable connection and reducing resistance to the rebound of the archwire 2. The adhesive layer at the bottom of the bracket body 1 ensures a firm connection with the teeth. The outer arc-shaped rail limits the position of the archwire 2, preventing excessive elongation at the end from irritating the oral cavity. The surface of the arched limiting piece 4 is smooth, reducing irritation to the oral mucosa. The baffles 42 at both ends of the snap fastener 41 prevent debris from entering. The special cross-sectional design of the arched limiting piece 4 holds the archwire 2 against it, preventing its initial displacement. When the archwire 2 deforms and bends back, the arched limiting piece 4 gradually shifts under the action of elasticity, switching the area of ​​orthodontic force application, precisely controlling the tooth movement path and force distribution, while preventing the archwire 2 from straightening back due to oral muscle peristalsis, which would irritate the oral cavity. When installing this utility model, the arched limiting piece 4 is located on the upper part of the maxillary teeth and on the lower part of the mandibular teeth, with the direction of bending changing accordingly. This invention solves the stimulation problem of traditional orthodontic appliances, achieving rapid and gradual correction, shortening the treatment period, and is especially suitable for children.

[0032] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
