[0037] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0038] The inventors have found that when orthodontic accessories are directly fixed to braces, a structure for installing the orthodontic accessories needs to be provided on the braces, which has complex design and processing techniques and high costs; and is not conducive to replacing orthodontic accessories in different correction steps.

[0039] The utility model aims to provide an accessory interface 1 detachably connected to the braces 2, which is a connecting link between the braces 2 and the orthodontic accessories 3, simplifies the design and manufacturing process of the braces 2, and improves the convenience of installing the orthodontic accessories 3.

[0040] Please refer to Figure 1 to Figure 7 As shown, the accessory interface 1 of the utility model comprises a connecting portion 11, a mounting portion 12 for mounting an orthodontic accessory 3, and a first receiving groove 13 formed between the connecting portion 11 and the mounting portion 12. The connecting portion 11 cooperates with the first receiving groove 13 to achieve the connection between the accessory interface 1 and the braces 2.

[0041] Along the arrangement direction of the connecting portion 11 and the mounting portion 12, the width of the opening of the first receiving groove 13 is smaller than the inner width of the first receiving groove 13, and can be clamped on the braces 2 without gluing or other mechanical locks. The connection method is simple, stable and reliable, and can be disassembled and assembled without damage, and can be transferred from the braces 2 of one correction step to the braces 2 of the next correction step. It can be operated by patients or other non-professionals, which improves the convenience of installing the orthodontic accessory 3 relying on this accessory interface 1.

[0042] Preferably, the accessory interface 1 is connected to the mounting boss of the braces 2, and the mounting boss is inserted into the first receiving groove 13; or the connecting portion 11 is inserted between the braces 2 and the teeth, and the mounting boss enters and is received in the first receiving groove 13. Further, the connecting portion 11 is provided with a buckle 111 protruding toward the mounting portion 12, and the buckle 111 is located at the opening of the first receiving groove 13, so that the width of the opening of the first receiving groove 13 is further reduced, so as to prevent the accessory interface 1 and the braces 2 from falling off during use; and when a hook 21 is provided at the mounting boss of the braces 2, it can also cooperate with the hook 21 to improve the stability of installation.

[0043] Preferably, the buckle 111 is provided with a guide surface 112 to guide the mounting boss of the braces 2 to smoothly enter the first receiving groove 13. In this embodiment, the guide surface 112 is located on the outer side of the buckle 111 facing away from the first receiving groove 13. The guide surface 112 is an inclined surface or an arc surface, and the guide surface 112 extends from the connecting portion 11 to the mounting portion 12 and into the first receiving groove 13.

[0044] Furthermore, at least one of the mounting portion 12 and the connecting portion 11 is an elastic film commonly used in the art, such as a resin film; or the mounting portion 12 is elastically connected to the connecting portion 11. Therefore, when subjected to external force, the free ends of the connecting portion 11 and the mounting portion 12 can move away from each other within a predetermined elastic range, so that the opening of the first receiving groove 13 expands, which is convenient for installation; and when the external force disappears, the free ends of the connecting portion 11 and the mounting portion 12 return to their original state, and the opening retracts to its original state. This "elastic connection" can be achieved by using any elastic connector.

[0045] The utility model can adaptably install different orthodontic accessories 3 through the installation part 12. Specifically, the installation part 12 is provided with at least one installation structure for installing the orthodontic accessory 3, so as to realize the connection between the orthodontic accessory 3 and the accessory interface 1.

[0046] When the mounting portion 12 is provided with at least two mounting structures for mounting orthodontic accessories 3, at least two of the mounting structures are used to mount different orthodontic accessories 3 to achieve different treatment effects; or at least two of the mounting structures are used to mount orthodontic accessories 3 in different correction steps to adapt to correction in different steps.

[0047] Under the premise of having at least one or at least two mounting structures, one of the mounting structures is a second receiving groove 121, and the second receiving groove 121 is located in the first receiving groove 13; that is, the second receiving groove 121 is opened on the groove wall constituting the first receiving groove 13, or the second receiving groove 121 is formed by a recessed arrangement of the groove wall of the first receiving groove 13. The second receiving groove 121 is embedded in the first receiving groove 13, so that the accessory interface 1 has a compact structure and a small volume.

[0048] The second receiving groove 121 passes through the mounting portion 12 in a direction intersecting the opening direction of the first receiving groove 13, and can be used to mount orthodontic accessories 3 having a filamentary connection portion, such as orthodontic arch wires and correction wires 32 for suspending jaw beads 31. The intersection angle is 90°±45°, preferably vertical.

[0049] Preferably, the second receiving groove 121 is located at the opening of the first receiving groove 13. After the orthodontic accessory 3 enters the first receiving groove 13, it quickly enters into the second receiving groove 121, which is convenient for disassembly and assembly, and the design of the interior of the first receiving groove 13 does not need to specially consider the size of the orthodontic accessory 3.

[0050] When the connecting portion 11 is provided with a buckle 111 protruding toward the mounting portion 12, and the buckle 111 is located at the opening of the first receiving groove 13, the buckle 111 overlaps with a portion of the second receiving groove 121 facing the opening, so that the orthodontic accessory 3 can quickly enter the second receiving groove 121. At the same time, the buckle 111 limits the orthodontic accessory 3 to prevent it from escaping from the second receiving groove 121.

[0051] Preferably, the overlapping range is not greater than 1 / 5 of the width W2 of the second receiving groove 121 in the opening direction of the first receiving groove 13. Therefore, most of the second receiving groove 121 is located on the inner side of the buckle 111, and a small part overlaps with the buckle 111. Therefore, after the orthodontic accessory 3 is placed in the second receiving groove 121, the buckle 111 does not interfere with its filamentary connection part. Preferably, the two are just in contact, and the buckle 111 presses on the filamentary connection part to limit it and prevent it from slipping out of the second receiving groove 121.

[0052] Furthermore, the width W1 of the first receiving groove 13 along the arrangement direction of the connecting portion 11 and the mounting portion 12 is smaller than the width W2 of the second receiving groove 121 in the opening direction of the first receiving groove 13, so that the orthodontic accessory 3 can be limited in the second receiving groove 121. Even if the orthodontic accessory 3 is out of the second receiving groove 121, it cannot move toward the inside of the first receiving groove 13. Therefore, the position of the orthodontic accessory 3 is relatively fixed, and a large amount of displacement will not occur during the correction process to affect the correction effect.

[0053] In addition, the opening directions of the first receiving groove 13 and the second receiving groove 121 are different, and the orthodontic accessory 3 needs to move in at least two directions to be separated from the accessory interface 1. Therefore, this design can also prevent the orthodontic accessory 3 from falling off the accessory interface 1.

[0054] It should be noted that the opening direction of the first receiving groove 13 is the direction opposite to the groove bottom, which is the entrance for the mounting boss of the braces 2 to enter the first receiving groove 13, which does not limit the braces 2 from other directions to enter the first receiving groove 13. The opening direction of the second receiving groove 121 is the direction opposite to the groove bottom, which is the entrance for the orthodontic attachment 3 to enter the second receiving groove 121, which does not limit the orthodontic attachment 3 to only enter the second receiving groove 121 from here.

[0055] like Figure 2 As shown, the second receiving groove 121 opens toward the connecting portion 11, and the opening directions of the two receiving grooves are substantially vertical, which effectively prevents the orthodontic attachment 3 from falling off. Figure 7 As shown, the opening of the second receiving groove 121 is inclined toward the connecting portion 11 and the opening of the first receiving groove 13, so as to facilitate the insertion of the filamentary connecting portion while preventing the filamentary connecting portion from falling off during use.

[0056] The above-described configuration of the first receiving groove 13 and the second receiving groove 121 can be used in any combination according to installation requirements to achieve an ideal installation effect.

[0057] Furthermore, along the extension direction of the second receiving groove 121, the size of the connecting portion 11 and the size of the mounting portion 12 located in the direction of the second receiving groove 121 away from the opening of the first receiving groove 13 are smaller than the size of other parts of the mounting portion 12, so the portion of the mounting portion 12 that exceeds the connecting portion 11 forms a stopper 14. The intersection angle is 90°±45°, preferably vertical intersection.

[0058] Specifically, taking the correction wire 32 for installing the jaw bead 31 as an example, the correction wire 32 is first bent into the following shape: Figure 4 The shape shown is placed in the second receiving groove 121, and rotates from the opening side of the first receiving groove 13 around the connecting portion 11 to the side where the mounting portion 12 is located, and abuts against the limiting portion 14. Then, the mounting boss of the mouthpiece 2 is inserted into the first receiving groove 13, and the filamentary connecting portion is limited between the mounting boss of the mouthpiece 2 and the limiting portion 14.

[0059] The utility model also provides an oral orthodontic device, comprising a dental brace 2 and any one of the above-mentioned accessory interfaces 1.

[0060] The mouthpiece 2 comprises a shell-shaped body and a mounting boss on the shell-shaped body 21. The mounting boss of the mouthpiece 2 is inserted into the first receiving groove 13 to achieve the connection between the accessory interface 1 and the mouthpiece 2. Alternatively, the connection portion 11 of the accessory interface 1 is inserted between the mounting boss of the mouthpiece 2 and the tooth to achieve the connection with the mouthpiece 2.

[0061] The structure of the mounting boss is not limited, as long as it can be inserted into the first receiving groove 13. Preferably, the mounting boss is a bulging boss with a certain gap between the mounting boss and the teeth to accommodate the connecting portion 11.

[0062] The position of the mounting boss is adaptively adjusted according to the orthodontic accessories to be installed. Taking the installation of the jaw bead 31 as an example, the mounting boss is located at a position corresponding to the upper jaw on the braces 2. Taking the installation of the archwire as an example, the mounting boss is preferably located on the buccal or lingual side of the braces 2, and preferably located in the bicuspid or molar area of ​​the braces 2.

[0063] Furthermore, when the connecting portion 11 is provided with a buckle 111 protruding toward the mounting portion 12 , the brace 2 is provided with a hook 21 matching with the buckle 111 .

[0064] Furthermore, the oral orthodontic device further comprises an orthodontic attachment 3 fixed on the mounting portion 12 . Matching with the second receiving groove 121 , the orthodontic attachment 3 has a filamentary connection portion that can be placed in the second receiving groove 121 .

[0065] In one embodiment, the orthodontic attachment 3 includes a jaw bead 31 and a correction wire 32 for hanging the jaw bead 31. The attachment interface 1 is snapped onto the upper braces 2 worn on the upper teeth, and the ball is located close to the upper palate to ensure that the tongue can reach it.

[0066] In another embodiment, the orthodontic accessory 3 is a correction arch wire, and the accessory interface 1 can be snapped onto the upper braces 2 or the lower braces 2 as needed to install the correction arch wire.

[0067] The jaw beads 31 and the correction arch wire are commonly used orthodontic accessories in the art, and their usage and treatment process will not be described in detail here.

[0068] In summary, in the accessory interface 1 of the utility model, the width of the opening of the first receiving groove 13 is smaller than the width of the inside of the first receiving groove 13, so the braces 2 can be clamped without gluing or other mechanical locks, and the connection method is simple, stable and reliable, and can be disassembled and assembled without damage, and can be transferred from the braces 2 of one correction step to the braces 2 of the next correction step, and can be operated by patients or other non-professionals, thereby improving the convenience of installing the orthodontic accessories 3 relying on this accessory interface 1.
