Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0051] To better understand the orthodontic appliance of this application, the following description is provided in conjunction with the accompanying drawings.

[0052] Example 1

[0053] like Figure 1-6As shown, an orthodontic appliance includes a traction locking member 1 and a main body 2. The traction locking member 1 is detachably mounted on the main body 2, allowing for timely removal and replacement by the doctor during treatment. The main body 2 includes a base and a cover 24. The base has a groove 22 for installing the archwire 3, dividing the base into a first end 21 and a second end 23. The cover 24 is movably connected to the second end 23 and is used to open or close the groove 22. In this embodiment, a slide rail can be provided on the cover 24, and a groove can be provided on the top of the second end 23, thereby achieving a movable connection between the cover 24 and the second end 23. In this embodiment, the movable connection between the cover 24 and the second end 23 makes opening or closing the groove 22 more convenient, allowing the doctor to quickly install or adjust the archwire 3 and reduce operation time. In other embodiments, the cover 24 can also be movably connected to the second end 23 by hinge or other means, which is not limited here. The sidewall of the cover 24 facing the first end 21 is the first sidewall 241, the lip side of the cover 24 is the first surface 242, the sidewall of the first end 21 facing the cover 24 is the second sidewall 211, and the lip side of the first end 21 is the second surface 212. In this embodiment, the first end 21 is provided with a relief groove 25, which penetrates part of the second sidewall 211 and part of the second surface 212. The traction locking member 1 includes a locking part 13, a connecting part 12, and a traction part 11. The connecting part 12 is used to connect the locking part 13 and the traction part 11. The locking part 13 is provided in the groove 22 for occupancy or locking. The connecting part 12 is at least partially located in the relief groove 25. The traction part 11 is located on the side of the first end 21 away from the second end 23. The traction locking member 1 in this embodiment has a traction function and can apply additional traction force by using an appropriate traction device according to the treatment and correction process to improve the correction effect.

[0054] In some other embodiments of this example, such as Figure 7-12 In the case of the cover 24, a relief groove 25 is provided, which penetrates a portion of the first sidewall 241 and a portion of the first surface 242. In some other embodiments of this example, relief grooves 25 may also be provided on both the first end 21 and the cover 24, with the relief grooves 25 penetrating a portion of the first sidewall 241, a portion of the first surface 242, a portion of the second sidewall 211, and a portion of the second surface 212.

[0055] During the use of the orthodontic appliance in this embodiment, the cover 24 has a closed state with the groove 22 closed and an open state with the groove 22 open. During orthodontic treatment, the cover 24 is first moved to open the groove 22, and then the traction locking member 1 is set. Specifically, the locking part 13 is provided in the groove 22, and the connecting part 12 for connecting the locking part 13 and the traction part 11 is at least partially located in the clearance groove 25. The clearance groove 25 penetrates part of the first sidewall 241 and part of the first surface 242, and / or the clearance groove 25 penetrates part of the second sidewall 211 and part of the second surface 212. The cover 24 is moved until the groove 22 is closed, so that the locking part 13 is located in the groove 22 for positioning or locking. "Positioning" means that the locking part 13 occupies the effective space in the groove 22, and the archwire 3 can still move as an orthodontic appliance. "Locking" means that the locking part 13 occupies the effective space in the groove 22, and the archwire 3 is fixed relative to the orthodontic appliance and cannot move. In this embodiment, the locking part 13 is positioned within the groove 22 to occupy or lock the position, thereby allowing for more precise adjustment of the archwire 3 parameters. By positioning the traction part 11 on the side of the first end 21 away from the second end 23, during orthodontic treatment, the traction part 11 is pulled by an elastic object (such as a rubber chain, rubber band, or traction elastic band) to move the teeth, thus improving the orthodontic effect. In some other embodiments, during orthodontic treatment, the cover 24 can be moved first to open the groove 22, the archwire 3 can be placed in the groove 22 first, and then the traction locking part 1 can be set. Then, the cover 24 can be moved until the groove 22 is closed. The specific adjustment can be made according to the shape of the traction locking part 1 and the ease of use for the doctor during treatment, and is not limited here.

[0056] In some embodiments of this example, the locking part 13 is disposed within the groove 22 and abuts against at least one sidewall of the groove 22. Specifically, the locking part 13 may abut against the sidewall of the groove 22 near the first end 21 or against the sidewall of the groove 22 near the second end 23. In this embodiment, by disposing the locking part 13 within the groove 22 and abutting against at least one sidewall of the groove, the locking part 13 can occupy the effective space within the groove 22 for positioning or locking.

[0057] In some embodiments of this example, the locking part 13 is disposed within the groove 22 and abuts against at least one sidewall of the groove. Specifically, as shown in the example... Figures 13-15 As shown, the locking part 13 can be set in an "n" shape from the perspective of the mesial-distal direction. That is, the locking part 13 includes a first locking wall 1311 located in the groove 22 near the first end 21, a second locking wall 1312 located near the second end 23, and a third top wall 1313 located in the groove near the cover 24. During orthodontic correction, the archwire 3 is placed in the space formed by the first locking wall 1311, the second locking wall 1312, and the third top wall 1313.

[0058] In some embodiments of this example, the locking part 13 is disposed within the groove 22 and abuts against at least one sidewall of the groove 22. Specifically, as Figures 16-18 As shown, the locking part 13 can be set in a "U" shape from the perspective of the mesial-distal direction. That is, the locking part 13 includes a first locking wall 1311 located in the groove 22 near the first end 21, a second locking wall 1312 located near the second end 23, and a fourth bottom wall 1314 located in the groove 22 away from the cover 24. During orthodontic correction, the archwire 3 is placed in the space formed by the first locking wall 1311, the second locking wall 1312 and the fourth bottom wall 1314.

[0059] In some embodiments of this example, the locking part 13 is disposed within the groove 22 and is close to one side wall of the groove. Specifically, the locking part 13 can be configured in an "L" shape from a mesiodistal perspective, that is, the locking part 13 includes a fourth bottom wall 1314 located within the groove 22 near the first end 21 and within the groove away from the cover 24. During orthodontic correction, the archwire 3 is disposed within the space formed by the first locking wall 1311, the fourth bottom wall 1314 and the cover 24.

[0060] In some embodiments of this example, the thickness of the portion of the locking part 13 adjacent to at least one sidewall of the groove 22 in the gingival-maxillary direction ranges from 0.1 mm to 0.5 mm. Specifically, when the thickness is less than 0.1 mm, the locking part 13 may not be strong enough and may be easily damaged. When the thickness is greater than 0.5 mm, the locking part 13 may occupy too much space in the groove 22, resulting in less remaining space in the groove 22, which may affect the placement and use of the archwire 3. Alternatively, it may cause the overall size of the groove 22 to be too large, resulting in an oversized main body 2, which may more easily scrape against the patient's mouth and affect the patient's comfort.

[0061] In some embodiments of this example, the portion of the locking portion 13 immediately adjacent to at least one sidewall of the groove 22 is not uniformly thick in the gingival-maxillary direction. Specifically, as Figures 19-23 As shown, the locking part 13 can be set into an X-shape or other shapes from the perspective of the labial and lingual direction. In this embodiment, by setting the thickness of at least one sidewall of the locking part 13 near the groove 22 in the labial and lingual direction to be not completely the same, the figure-eight back ligation on the canine can effectively control the overbite deepening.

[0062] In some embodiments of this example, the number of clearance slots 25 is at least two, such as... Figure 24-25 As shown, two clearance grooves 25 are provided at the first end 21. By providing two clearance grooves 25, the relative stability between the traction locking member 1 and the main body 2 can be further improved.

[0063] In some embodiments of this example, the lip side of the connecting portion 12 is smoothly connected to the first surface 242, such as... Figure 24-25 As shown, a smooth connection can be interpreted as the absence of obvious protrusions or depressions when transitioning from the lip side of the connecting part 12 to the first surface 242. Minor unevenness on the lip side of the connecting part 12 or the first surface 242 due to processing or other reasons is also within the protection scope of this embodiment.

[0064] In some embodiments of this example, the lip side of the traction part 11 is smoothly connected to the lip side of the connecting part 12. The smooth connection can be interpreted as the absence of obvious protrusions or depressions when transitioning from the lip side of the traction part 11 to the lip side of the connecting part 12. Minor unevenness on the lip side of the connecting part 12 or the lip side of the traction part 11 due to processing or other reasons is also within the protection scope of this example.

[0065] In some embodiments of this example, the locking part 13 is made of an elastic material. In this example, the locking part 13 is made of an elastic material. By using the locking part 13 made of an elastic material, it is possible to further adapt to different types of archwires 3, such as archwires 3 of different sizes or archwires 3 of different cross-sectional shapes, thereby improving the effect of orthodontic treatment.

[0066] In some embodiments of this example, the traction locking component is integrally molded. The traction locking component in this example is made by integral molding, which can improve the strength of the traction locking component and prevent the traction locking component from being damaged by traction during the orthodontic process.

[0067] Equivalently, "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is merely one embodiment for ease of reading, and is not intended to limit the scope of protection of this application. Any technical solution that includes the above features and has the same function should be understood as an equivalent technical solution of this application.

[0068] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0069] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0071] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0072] It should be noted that when a component is described as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable. Examples include socketing, snap-fitting, integral molding, and welding, which are feasible in conventional technologies and will not be elaborated upon here.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
