[0033] In modern human beings, the appearance of a person, especially the impression of his / her face, can be used as a standard for judgment in employment or admission interviews, and is a very important factor in human interaction and social life. In particular, the dentition state of a person becomes a decisive factor in his / her personal impression. Therefore, in addition to plastic surgery, orthodontic treatment for improving the state of teeth, tooth arrangement or the arrangement of facial bones has become common.

[0034] Such orthodontic treatment, i.e. the dental correction treatment for correcting misaligned teeth, aims to improve various bone abnormalities that can occur during growth, so as to realize normal functions, thereby helping to achieve a healthy oral structure. In addition, orthodontic treatment can change the oral anatomy, thereby providing a beautiful facial profile and a healthy facial image.

[0035] In the relative technical field, orthodontic components generally use traction hooks to pull the teeth to be corrected. Most of the existing traction hooks need to be selected in size before bonding, and it is difficult to change the length and direction during the treatment process.

[0036] The present application provides an adjustable orthodontic traction hook.

[0037] In the embodiment of the present application, as shown in Figures 1-4 The adjustable orthodontic traction hook 100 includes a bonding plate 110, a hook piece 120, and a traction arm 130. The bonding plate 110 is bonded and fixed to the crown surface of the tooth to be moved. The hook piece 120 is movably arranged relative to the bonding plate 110, and the hook piece 120 is used for detachable connection with the traction member. The traction arm 130 is connected between the bonding plate 110 and the hook piece 120, and the traction arm 130 includes a plurality of connection segments connected end to end. Among them, the angle between the adjacent two connection segments is set, and the angle is adjustable.

[0038] Specifically, in the embodiment of the present application, the adjustable orthodontic traction hook 100 includes a bonding plate 110, which is arranged in a substantially flat plate shape. In some embodiments, the bonding plate 110 can also be arranged in an arc shape to better fit the outer side of the tooth and improve the adhesion between the two, thereby making the connection between the bonding plate 110 and the tooth more stable. The back of the bonding plate 110 is bonded and fixed to the crown surface of the tooth to be moved, and the front of the bonding plate 110 is fixedly connected to one end of the traction arm 130. The traction arm 130 and the bonding plate 110 can be integrally formed in some embodiments, or can be separately formed and then welded or bonded and fixed, which is not specially limited here.

[0039] In the embodiment of the present application, the adjustable traction hook further includes a hook piece 120, which is used to connect with the traction member, so as to realize orthodontic traction. The traction hook often extends to the vicinity of the resistance center of the tooth, and the orthodontic force can pass through the resistance center, thereby reducing the inclined movement of the tooth. The traction member is generally a rubber band or a leather ring.

[0040] In the embodiment of the present application, the adjustable traction hook further comprises a traction arm 130 connected between the adhesive plate 110 and the hook piece 120 to provide traction between the hook piece 120 and the adhesive plate 110. The traction arm 130 can be made of a relatively soft metal. The traction arm 130 comprises a plurality of connection segments connected end to end, and adjacent two connection segments are arranged at an angle, and the angle can be adjusted as needed, so that the length of the traction arm 130 and the angle between the adhesive plate 110 and the hook piece 120 can be adjusted. In use, the angle between adjacent two connection segments can be adjusted by an orthodontic forceps (such as a wire bending forceps), so that the optimal traction length and angle required by various tooth positions can be met in real time without replacing the traction hook. At the same time, since only the angle between adjacent two connection segments needs to be adjusted by the orthodontic forceps to adjust the length and direction, the use length of the adjustable orthodontic traction hook 100 can be adjusted in real time during the correction of the patient's teeth according to the different heights of the patient's resistance center, improving the convenience of use, reducing the operation difficulty of the user, and improving the correction effect.

[0041] The adjustable orthodontic traction hook 100 provided by the present application comprises an adhesive plate 110, a hook piece 120 and a traction arm 130. The adhesive plate 110 is fixedly attached to the surface of the tooth crown to be moved. The hook piece 120 is movably arranged relative to the adhesive plate 110. The hook piece 120 is used to detachably connect with a traction piece. The traction piece is limited in movement in all directions after entering the hook piece, thereby preventing slipping. The traction piece can only exit from the original path when removed. The traction arm 130 is connected between the adhesive plate 110 and the hook piece 120. The traction arm 130 comprises a plurality of connection segments connected end to end. Among them, adjacent two connection segments are arranged at an angle, and the angle is adjustable. In the present application, the traction arm 130 is arranged to be connected end to end by a plurality of connection segments. Adjacent two connection segments are arranged at an angle, and the angle is adjustable. In this way, the length of the traction arm 130 and the angle between the traction arm 130 and the adhesive plate 110, or the angle between the traction arm 130 and the hook piece 120, can be controlled by adjusting the angle between adjacent two connection segments, so as to adapt to the changes of tooth correction in different stages, and to meet the optimal traction length and angle required by various tooth positions in real time without replacing the traction hook. At the same time, in actual use, the overall length of the adjustable orthodontic traction hook 100 and the tooth angle can be changed by adjusting the angle between adjacent two connection segments, improving the convenience of use, reducing the operation difficulty of the user, and being low in cost, which is conducive to the application and promotion of the product.

[0042] Reference Figures 1 to 3In some embodiments according to the present application, the two adjacent connecting segments are arranged at an acute angle. It can be understood that, in order to ensure that the traction arm 130 has a strong traction force and orthodontic effect, in the present embodiment, the two adjacent connecting segments of the traction arm 130 are arranged at an acute angle, so as to ensure that the yield strength between the two adjacent connecting segments is improved, thereby providing a reliable traction force between the bonding plate 110 and the hook piece 120. Of course, in other embodiments, the two adjacent connecting segments are arranged at an obtuse angle or a right angle, without being limited thereto.

[0043] With reference to Figure 1 In some embodiments according to the present application, the traction arm 130 includes a first connecting segment 131, a second connecting segment 132, and a third connecting segment 133. The leading end of the first connecting segment 131 is fixedly connected with the hook piece 120, and the trailing end of the third connecting segment 133 is connected with the bonding plate 110 away from the tooth crown surface. The first connecting segment 131, the second connecting segment 132, and the third connecting segment 133 are connected end to end. Alternatively, the traction arm 130 can include 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 connecting segments, which can be set according to actual needs. The present embodiment is described by taking an example of the traction arm 130 including three connecting segments, and other embodiments can be implemented with reference to the present embodiment. Specifically, the traction arm 130 includes the first connecting segment 131, the second connecting segment 132, and the third connecting segment 133. The leading end of the first connecting segment 131 is fixedly connected with the hook piece 120, and can also be rotatably connected, without being limited thereto. The leading end of the second connecting segment 132 is connected with the trailing end of the first connecting segment, and the trailing end of the third connecting segment is connected with the bonding plate 110, which can be bonded, welded, or the like. The leading end of the third connecting segment is connected with the trailing end of the second connecting segment, so as to connect the hook piece 120 to the bonding plate 110 through the traction arm 130. Of course, in other embodiments, the fourth connecting segment 134 can be included, or the third connecting segment 133 can not be included, without being limited thereto. Further, the first connecting segment 131, the second connecting segment 132, and the third connecting segment 133 are integrally formed. Thus, the structural strength of the traction arm 130 is improved, and the generation of internal stress is reduced. Of course, in other embodiments, each connecting segment can be separately provided and then connected through a hinge. The hinge is fastened to ensure that the included angle is adjustable and a certain traction strength is ensured.

[0044] With reference to Figure 1 In some embodiments according to the present application, the traction arm 130 includes three connecting segments, and the traction arm 130 is arranged in a “Z” shape or an “N” shape. In the present embodiment, the three connecting segments are connected end to end to form the traction arm 130 in a “Z” shape or an “N” shape, thereby being connected between the bonding plate 110 and the hook piece 120.

[0045] Referring to Figure 2 , according to some embodiments provided by the present application, the traction arm 130 comprises two connecting segments, and the traction arm 130 is arranged in a "V" shape. In this embodiment, the traction arm 130 is connected between the adhesive plate 110 and the hook piece 120 by connecting the two connecting segments end to end to form a "V" shaped traction arm 130. The "V" shaped traction arm 130 can be applied to some teeth with small traction distance, thereby improving the adaptability of the adjustable orthodontic traction hook 100.

[0046] Referring to Figure 3 , according to some embodiments provided by the present application, the traction arm 130 comprises four connecting segments, and the traction arm 130 is arranged in a "W" shape or an "M" shape. In this embodiment, the traction arm 130 is connected between the adhesive plate 110 and the hook piece 120 by connecting the four connecting segments end to end to form a "W" shaped or an "M" shaped traction arm 130. The "W" shaped or "M" shaped traction arm 130 can be applied to some teeth with large traction distance, thereby improving the adaptability of the adjustable orthodontic traction hook 100.

[0047] Referring to Figure 4 , according to some embodiments provided by the present application, the hook piece 120 comprises a connecting part 121 and a hooking part 122, the connecting part 121 is connected to one end of a connecting segment of the traction arm 130 away from the adhesive plate 110, and the hooking part 122 is connected to the traction piece. It can be understood that the connecting part 121 is used for connecting one end of the traction arm 130, and the hooking part 122 is used for detachable limiting connection with the traction piece, so that the traction piece can be replaced as needed. The hooking part 122 is connected end to end by a plurality of open steel rings 123, and is formed by partially overlapping each other. It can be understood that the existing hook piece 120 is mostly zigzag-shaped. When the angle between the traction force and the traction arm 130 is 90 degrees, the traction leather ring is not easy to slip off. However, with the movement of the teeth, especially in the process of supporting the teeth, the change of the angle of the teeth makes the direction of the traction force no longer 90 degrees with the traction arm 130, which is easy to make the traction leather ring slip off. In this embodiment, the hooking part 122 of the hook piece 120 matched with the leather ring is arranged as a ring-shaped lock hook connected end to end by a plurality of open steel rings 123, and formed by partially overlapping each other, and the connecting part 121 is arranged at the outer ring of the steel ring 123. The leather ring can enter the inner ring of the hook piece 120 as needed, so that the adjustable traction hook can stably hold the leather ring, greatly reducing the risk of leather ring slipping off during use, and improving the connection reliability of the adjustable orthodontic traction hook 100.

[0048] Referring to Figures 1 to 4 , according to some embodiments provided by the present application, a welding small ball is arranged at the end of the inner ring of the hook piece 120, and the welding small ball is used for facilitating the taking, placing and connecting and fixing of the traction piece.
