Description

Technical Field

[0001] The present disclosure relates to the technical field of dental orthodontics, and in particular to a lingual personalized free hook. Background Art

[0002] With the popularization and promotion of orthodontics, orthodontic treatment is becoming more and more accepted by the public. In orthodontic treatment, tooth extraction is very common. An essential step in tooth extraction is to close the extraction gap. During the tooth movement process, if the traction tool is directly hung on the bracket for traction, the direction and magnitude of the force on the tooth are different, which can easily lead to tooth axis tilt, torque and torque loss.

[0003] The free hook is an instrument used for correcting teeth. The free hook can be fixed on the teeth or buckled on the braces to control the movement of the teeth. The working principle of the free hook is to use its position and shape to guide the force of correcting the teeth and lead the teeth to the desired position. The free hook is a common device used to pull the arch wire in the sliding method of straight wire braces. In the related art, the distance between the anterior teeth of the personalized lingual brackets is small, resulting in a relatively short effective length of the exposed arch wire. The usual straight and long free hooks often do not have enough space for retention, and if the straight and long free hooks are not well retained, the free hooks will slide on the arch wire, resulting in the problem of failure to play a traction role or even falling off. Utility Model Content

[0004] The present disclosure provides a personalized lingual free hook to solve or alleviate one or more technical problems in the prior art:

[0005] As a first aspect of an embodiment of the present disclosure, the embodiment of the present disclosure provides a lingual personalized free hook, comprising:

[0006] A clamping seat, the clamping seat comprising a clamping slot, the clamping slot comprising a first sub-slot and a second sub-slot, the first sub-slot and the second sub-slot being arranged at an angle, the angle between the first sub-slot and the second sub-slot being in a range of 90°-180°; and

[0007] A traction rod, one end of which is connected to the clamping seat.

[0008] In some possible implementations, the clamping seat includes relatively arranged clamping parts, one end of the clamping parts is connected by a connecting part, the clamping groove is formed between the clamping part and the connecting part, the clamping part includes a first inclined part and a second inclined part, one end of the first inclined part and the second inclined part are connected, and the angle between the first inclined part and the second inclined part is in the range of 90°-180°, and the traction rod is connected to one side of the clamping part away from the clamping groove.

[0009] In some possible implementations, the clamping portion and the connecting portion are integrally formed.

[0010] In some possible implementations, the clamping seat further includes a protrusion, which is provided on an opposite surface of the clamping portion, and the protrusion is located at an opening of the clamping groove of the clamping portion.

[0011] In some possible implementations, at least one traction hook is provided at one end of the traction rod away from the clamping seat.

[0012] In some possible implementations, the sum of the lengths of the traction hook and the traction rod is in the range of 5-20 mm, the length of the traction hook is the dimension of the traction hook in the radial direction of the traction rod, and the length of the traction rod is the dimension of the traction rod in the radial direction.

[0013] In some possible implementations, there are multiple traction hooks, and the multiple traction hooks are arranged along the length direction of the traction rod.

[0014] In some possible implementations, the traction hook and the traction rod are integrally formed.

[0015] In some possible implementations, the traction rod and the clamping seat are integrally formed.

[0016] In some possible implementations, the width of the clamping groove ranges from 0.9 mm to 2 mm, and the width of the clamping groove is the dimension of the clamping groove in a radial direction perpendicular to the traction rod.

[0029] The contents of the present disclosure are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Figure 1 This is a diagram of personalized brackets installed on teeth. Figure 2 This is a schematic diagram of a straight long free hook installed on an arch wire in the related art. Figure 3 Schematic diagram of a straight long free hook in related art. Figure 1 and Figure 2 As shown, the custom brackets 10 of a conventional lingual brace are fixed on the teeth 20, and the extension lines of the alveolar grooves of adjacent custom brackets 10 intersect, so that the extension lines of the alveolar grooves of adjacent custom brackets 10 form an angle. Figure 1 The personalized lingual bracket of the related art has a smaller distance between the front teeth, resulting in a shorter effective length of the exposed arch wire 30 , and the conventional straight and long free hook 40 often does not have enough space for retention.

[0031] Reference Figure 2 As shown, the straight long free hook 40 is fixed at the intersection of the arch wire 30 of the adjacent personalized bracket 10. The straight long free hook 40 has a poor retention effect, causing the straight long free hook 40 to slide on the arch wire 30, which may cause the straight long free hook 40 to fail to play a traction role or even fall off. Figure 3 As shown, the clamping grooves of the current straight long free hooks 40 are all straight, and the arch wire needs to have a sufficient exposed length. In the labial braces, the distance between the brackets is large and the arch wire is exposed more, so the straight long free hooks can be used. However, in the lingual braces, the distance between the anterior teeth brackets is small and the exposed length of the arch wire is limited. The straight long free hooks often do not have enough arch wire length for retention.

[0032] In order to solve the problem in the related art that a straight and long free hook cannot play a traction role due to poor retention, an embodiment of the present disclosure provides a lingual personalized free hook. The lingual personalized free hook of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0033] Figure 4 This is a schematic diagram of the matching installation of the lingual personalized free hook and the arch wire according to an embodiment of the present disclosure; Figure 5 A schematic diagram of a personalized free hook on the lingual side according to an embodiment of the present disclosure; Figure 6 This is a frontal schematic diagram of the lingual personalized free hook according to an embodiment of the present disclosure; Figure 7 A schematic side view of a lingual personalized free hook according to an embodiment of the present disclosure; Figure 8 This is a frontal plan view of a lingual personalized free hook according to an embodiment of the present disclosure; Figure 9 This is a side perspective schematic diagram of the lingual personalized free hook according to the embodiment of the present disclosure. Figures 4 to 9 As shown, the disclosed embodiment provides a personalized lingual free hook. The personalized lingual free hook 50 includes a clamping seat 100 and a traction rod 200. Specifically, the clamping seat 100 includes a clamping groove 110. The clamping groove 110 includes a first sub-groove 111 and a second sub-groove 112. The first sub-groove 111 and the second sub-groove 112 are arranged at an angle, and the angle between the first sub-groove 111 and the second sub-groove 112 ranges from 90° to 180°. One end of the traction rod 200 is connected to the clamping seat 100.

[0034] Reference Figures 1 to 3 As shown, for example, the long free hook in the lingual brace may be welded between the 2nd tooth and the 3rd tooth. In the personalized bracket design, the extension line of the alveolar groove of the 2nd tooth and the 3rd tooth will intersect, and the extension line of the alveolar groove of the 2nd tooth and the 3rd tooth will form an angle. Figure 2 As shown, the straight free hook of the related art is fixed at the intersection of the arch wire of the personalized brackets of teeth 2 and 3. The straight long free hook has a poor retention effect, causing the free hook to slide on the arch wire, which may cause the straight long free hook to fail to play a traction role or even fall off. Figure 4As shown, the range of the angle between the first sub-groove 111 and the second sub-groove 112 of the lingual personalized free hook 50 of the embodiment of the present invention matches the angle of the intersecting arch wire of the personalized brackets of teeth No. 2 and No. 3, that is, the angle of the first sub-groove 111 and the second sub-groove 112 can be determined according to the intersection angle of the extension lines of the alveolar grooves of teeth No. 2 and No. 3 of each customer, and the personalized free hook can perfectly match the actual bent arch wire at the bending position between teeth No. 2 and No. 3, and the lingual personalized free hook can also personalize the width according to the actual bracket spacing to ensure that it can perfectly cooperate with the arch wire without interfering with the brackets of adjacent teeth.

[0035] It should be noted that the angle between the first sub-groove 111 and the second sub-groove 112 is in the range of 90°-180°. The specific numerical value of the range of the angle between the first sub-groove 111 and the second sub-groove 112 is not limited here and can be set according to actual use requirements. For example, the angle between the first sub-groove 111 and the second sub-groove 112 can be determined based on the angle at which the extension lines of the alveolar grooves of teeth No. 2 and No. 3 intersect. For example, the angle between the first sub-groove 111 and the second sub-groove 112 can be any one of 100°, 110°, 120°, 130°, 140°, 150°, 160°, and 170°.

[0036] For example, the specific shape and size of the clamping groove 110 can be set according to the shape and size of the actual archwire. One end of the traction rod 200 is connected to the clamping seat 100. The specific shape of the traction rod 200 is not limited here. For example, the traction rod 200 can be a round rod.

[0037] For example, the traction rod 200 and the clamping seat 100 are integrally formed or the traction rod 200 and the clamping seat 100 can be fixedly connected by fasteners.

[0038] The straight free hooks of the related art have poor retention effects, causing the free hooks to slide on the arch wire, which can cause the straight, long free hooks to fail to provide traction or even fall off. The lingual personalized free hook of the disclosed embodiment has a clamping groove 110 configured as a first sub-groove 111 and a second sub-groove 112 that intersect and form an angle. The angle between the first sub-groove 111 and the second sub-groove 112 ranges from 90° to 180°. This matches the curved design of the arch wire, allowing the clamping seat 100 to be better fixed on the arch wire. Furthermore, after clamping, there is a certain gap between the clamping groove 110 and the arch wire, and there is only a small range of shaking. The free hook will not slide on the arch wire and fail to provide traction.

[0039] Reference Figures 5 to 9As shown, in a disclosed embodiment, the clamping seat 100 includes opposing clamping portions 120, one end of which is connected by a connecting portion 130, and a clamping groove 110 is formed between the clamping portion 120 and the connecting portion 130. The clamping portion 120 includes a first inclined portion 121 and a second inclined portion 122, one end of the first inclined portion 121 and the second inclined portion 122 are connected, and the angle between the first inclined portion 121 and the second inclined portion 122 ranges from 90° to 180°. The traction rod 200 is connected to a side of the clamping portion 120 away from the clamping groove 110.

[0040] Exemplarily, one end of the clamping portion 120 is connected by a connecting portion 130, thereby forming a clamping groove 110 with one end open. Both clamping portions 120 include a first inclined portion 121 and a second inclined portion 122, which are arranged at an angle relative to the radial direction of the pull rod. One end of the first inclined portion 121 and the second inclined portion 122 are connected, and the angle formed by the connected ends of the first inclined portion 121 and the second inclined portion 122 ranges from 90° to 180°. The first inclined portion 121 and the second inclined portion 122 contact and clamp the archwire.

[0041] For example, the clamping portion 120 and the connecting portion 130 are integrally formed. That is, the clamping groove 110 can be formed by providing a groove on the clamping base 100 that extends through one end of the clamping base 100. It should be noted that the clamping portion 120 and the connecting portion 130 can also be assembled to form the clamping groove 110. The specific configuration of the clamping portion 120 and the connecting portion 130 can be customized based on actual usage requirements.

[0042] Reference Figures 5 to 9 As shown, in one disclosed embodiment, the clamping seat 100 further includes a raised portion 140, which is disposed on a surface opposite the clamping portion 120 and is located at the opening of the clamping slot 110 of the clamping portion 120. Exemplarily, the raised portion 140 extends along the length of the opening of the clamping slot 110 and protrudes relative to the surface opposite the clamping portion 120. The raised portion 140 is located at the opening of the clamping slot 110 and serves to prevent the arch wire from moving outward. The clamping slot 110 and the raised portion 140 together secure the clamping seat 100 to the arch wire.

[0043] In a disclosed embodiment, at least one traction hook 300 is provided at one end of the traction rod 200 away from the clamping seat 100, and the traction hook 300 is integrally formed with the traction rod 200. Figures 5 to 9 As shown, the traction hook 300 can be a round-headed traction hook provided at the end of the traction rod 300 away from the clamping seat 100. It should be noted that the specific shape of the traction hook 300 can be set according to actual use requirements.

[0044] In a disclosed embodiment, the sum of the lengths of the traction hook 300 and the traction rod 200 ranges from 5 mm to 20 mm. The length of the traction hook 300 is the radial dimension of the traction hook 300 in the traction rod 200 , and the length of the traction rod 200 is the radial dimension of the traction rod 200 .

[0045] Figure 10 This is a schematic diagram of the dimensions of the lingual personalized free hook according to the embodiment of the present disclosure. Figure 10 As shown, the sum of the lengths of the towing hook 300 and the towing rod 200 is L. For example, L ranges from 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, 17 mm, 19 mm, and 20 mm. The specific size of the sum of the lengths of the towing hook 300 and the towing rod 200 is not limited herein.

[0046] Figure 11 Schematic diagram of the lingual personalized free hook of the embodiment of the present disclosure. Figure 11 As shown, for example, there are multiple towing hooks 300, and the multiple towing hooks 300 are arranged along the length direction of the towing rod 200. For example, there are two towing hooks 300, and the two towing hooks 300 are arranged along the length direction of the towing rod 200. The specific number of towing hooks 300 can be set according to actual usage requirements.

[0047] In a disclosed embodiment, the width of the clamping groove 110 ranges from 0.9 mm to 2 mm, where the width of the clamping groove 110 refers to the dimension of the clamping groove 110 in a radial direction perpendicular to the traction rod 200 .

[0048] Reference Figure 10 As shown, the width dimension of the clamping groove 110 is W. For example, the range of W is 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, and 2.0 mm.

[0049] In related art, due to the small spacing between anterior brackets, the exposed length of the archwire is limited, and straight free hooks often lack sufficient archwire length for retention. However, the disclosed embodiment allows for customized definition of the width of the clamping groove 110, ensuring perfect fit with the archwire without interfering with adjacent brackets, thereby achieving a perfect match for the archwire at the bend where the alveolar grooves of adjacent teeth intersect.
