Description

Technical Field

[0001] This application relates to the field of orthodontic technology, and more specifically, to an insertable long-arm traction hook and a multi-hook buccal tube. Background Technology

[0002] In fixed orthodontic treatment, doctors usually use intramaxillary traction to achieve key treatment goals such as gap closure, midline alignment, adjustment of anterior overbite and overjet, and improvement of posterior occlusal relationship.

[0003] During orthodontic treatment, brackets are fixed to the misaligned teeth requiring correction, while buccal tubes are fixed to the surfaces of the premolars or molars on either side to secure the ends of the archwire. The buccal tube consists of a base plate, a main body, and traction hooks. The base plate is bonded to the tooth crown surface, the main body houses the archwire, and the traction hooks are used to suspend auxiliary instruments such as bands. The buccal tube is typically bonded to the molar area to prevent the ends of the archwire from being directly exposed in the oral cavity, which could scratch the oral mucosa and cause oral diseases. During use, the end of the archwire is passed through the tube, and the traction hooks on the buccal tube are used to attach orthodontic elastics for traction.

[0004] For example, application number 202322768861.1 discloses a long-arm multi-hook cheek tube, which realizes a long-arm multi-hook cheek tube through the mutual cooperation of a concave block, a rotating shaft, an adjusting block, a first long-arm hook, a second long-arm hook, a rotating block, a through port, a threaded rod, a threaded block, a locking block, and a locking groove.

[0005] The drawback of the aforementioned long-arm multi-hook buccal tube is that its first and second long hooks may come into contact with the soft tissue of the gums, potentially causing pressure on the gums.

[0006] Therefore, existing technologies need to be improved. Utility Model Content

[0021] The second tenon is located at the end of the first tenon, and the size of the second tenon is smaller than that of the first tenon.

[0022] In one embodiment, the first tenon includes:

[0023] First column;

[0024] A first contraction section extends from the traction arm toward the first column, and the first contraction section is used to connect the traction arm and the first column.

[0025] The second contraction portion extends from the first column towards the second tenon side and is used to connect the first column and the second tenon.

[0042] Example 1:

[0043] Please see Figure 1 This embodiment provides an insertable long-arm traction hook, which includes a tenon tongue 100, a traction arm 200 and at least one traction hook 300. The tenon tongue 100 is used to be installed on the cheek tube 400. The traction arm 200 is connected to the side of the tenon tongue 100 away from the cheek tube 400, and a certain angle θ is provided between the traction arm 200 and the tenon tongue 100. The traction hook 300 is disposed at the end of the traction arm 200 away from the tenon tongue 100.

[0044] In this embodiment, the cheek tube 400 ( Figure 3 (As shown) is an important component of a fixed orthodontic appliance. The buccal tube 400 includes a body 410 and an insertable long-arm traction hook 300 mounted on the body 410. The body 410 has a vertical attachment tube, within which the traction arm 200 is installed. The traction hook 300 is used to attach rubber bands or tension springs for intramaxillary or intermaxillary traction. Typically, the traction hook 300 is not used throughout the entire orthodontic period, but only in the early or later stages of orthodontic treatment. Therefore, when the traction hook 300 is not needed, it can be removed to avoid irritating the oral mucosa.

[0045] This insertable long-arm traction hook includes a tenon tongue 100, a traction arm 200, and at least one traction hook 300. A certain angle θ is formed between the traction arm 200 and the tenon tongue 100. When the tenon tongue 100 is installed, it can be inserted into the vertical attachment tube on the buccal tube 400. The traction hook 300 is used to attach rubber bands or tension springs, etc. Therefore, the rubber bands or tension springs can exert a force at a certain angle θ on the tenon tongue 100, allowing the tenon tongue 100 to form a stable self-locking structure with the buccal tube 400. The tenon tongue 100 effectively prevents the traction hook 300 from rotating or sliding within the vertical attachment tube when under force. While ensuring stable traction, this allows for more precise overall tooth movement, helping the tooth to smoothly shift along the expected trajectory. Furthermore, dentists can flexibly remove it according to the specific tooth position and treatment time requirements, without needing to leave it continuously in the patient's mouth for extended periods. This ensures its effective clinical application and significantly improves patient comfort. At the same time, a certain angle θ is set between the traction arm 200 and the tenon tongue 100, that is, the traction hook 300 is deviated from the side away from the gum, so that the traction hook 300 on the traction arm 200 can avoid the gum, effectively avoiding pressure and discomfort on the gum.

[0046] As can be seen, this insertable long-arm traction hook is a detachable, split traction hook 300, which works in conjunction with a vertical accessory tube designed inside the buccal tube 400 or bracket. This design allows dentists to flexibly choose whether to place the traction hook 300, as well as the specific tooth position and duration of placement, based on each patient's oral condition and treatment needs. Combined with professional auxiliary treatment tools, such as rubber bands or springs, this enables personalized treatment plans and more refined orthodontic results.

[0047] When treatment reaches a certain stage and the traction hook 300 is no longer necessary, the doctor can easily remove it, avoiding the discomfort that prolonged wear might cause to the patient. This ensures its effective clinical application while preventing the continuous presence of the traction hook 300 throughout the entire treatment cycle, thus significantly reducing the incidence of oral mucosal abrasions caused by accidental contact or friction from the traction hook 300. Orthodontic treatment often involves a relatively long period. During this process, even minor discomfort can affect the patient's treatment experience and compliance. This removable design is precisely from the patient's perspective, creating a more comfortable and healthier treatment environment by reducing unnecessary friction and damage.

[0048] Therefore, in this application, a certain angle θ is provided between the tenon tongue 100 and the traction arm 200, so that the traction arm 200 can avoid the gums, effectively avoiding pressure and discomfort on the gums, ensuring its functionality in clinical applications, and further improving the comfort of patients when wearing it.

[0049] Optionally, the included angle θ between the traction arm 200 and the tenon tongue 100 is 5-15°.

[0050] For example, please see Figure 1 The angle θ between the traction arm 200 and the tenon tongue 100 is 5-15°, which causes the traction arm 200 and the traction hook 300 to shift away from the gum line, allowing the traction hook 300 on the traction arm 200 to avoid the gum line and effectively prevent pressure on the gum line.

[0051] Specifically, please refer to Figure 1 The towing hook 300 includes a first towing hook 300a and a second towing hook 300b. The first towing hook 300a is disposed at one end of the towing arm 200 away from the tenon tongue 100, and the second towing hook 300b is disposed on the first towing hook 300a. The first towing hook 300a and the second towing hook 300b are connected in series.

[0052] In this embodiment, two traction hooks 300 are provided, namely a first traction hook 300a and a second traction hook 300b, and the first traction hook 300a and the second traction hook 300b are connected in series. This design can meet the diverse needs of high and low traction in clinical practice. For example, when using the first traction hook 300a, it is less likely to scratch the patient's oral mucosa compared to the straight-arm traction hook 300, thereby reducing the possibility of oral ulcers; when using the second traction hook 300b, the traction force point can be closer to the resistance center of the tooth, which is closer to the overall movement of the tooth and reduces tilting movement. In actual operation, when it is necessary to adjust the traction position according to the patient's specific condition, the doctor only needs to adjust the position of the traction hook 300 fixed by the rubber band, without the need for cumbersome removal and repositioning of the traction hook 300, which greatly improves the convenience of operation.

[0053] It should be understood that the number of towing hooks 300 is not limited to the two mentioned above, and the number of towing hooks 300 can also be in other cases, which are not limited here.

[0054] Specifically, please refer to Figure 1 The towing hook 300 includes a connecting arm 310 and an arc-shaped hook body 320, the arc-shaped hook body 320 being connected to the end of the connecting arm 310.

[0055] In this embodiment, the traction hook 300 includes a connecting arm 310 and an arc-shaped hook body 320. For example, the connecting arm 310 of the first traction hook 300a is connected to the traction arm 200, and the top of the arc-shaped hook body 320 of the first traction hook 300a is connected to the second traction hook 300b. The connecting arm 310 of the second traction hook 300b is connected to the arc-shaped hook body 320 of the first traction hook 300a, so as to realize the series connection of the first traction hook 300a and the second traction hook 300b. The structure is simple and easy to implement, and can meet the diverse needs of high and low traction in clinical practice.

[0056] Optionally, the arc-shaped hook 320 includes a semi-circular hook body connected to the end of the connecting arm 310.

[0057] The arc-shaped hook 320 includes a semi-circular hook body, meaning the arc-shaped hook 320 is designed as a semi-circular hook body, presenting a smooth curved surface shape, which is less likely to scratch the patient's oral mucosa. For example, both the first traction arm 200 and the second traction arm 200 adopt an arc-shaped design with a smooth transition. In actual use, compared with the traditional straight-arm traction hook 300, this design is less likely to scratch the patient's oral mucosa, reducing the possibility of oral ulcers and significantly improving patient comfort.

[0058] Specifically, please refer to Figure 1The tenon 100 includes a first tenon 110 and a second tenon 120. The first tenon 110 is located on the side of the traction arm 200 away from the traction hook 300, and the second tenon 120 is located at the end of the first tenon 110. The size of the second tenon 120 is smaller than that of the first tenon 110.

[0059] In this embodiment, the tenon 100 includes a first tenon 110 and a second tenon 120. The tenon 100 fits tightly with the vertical attachment tube on the buccal tube 400, forming a stable tenon-and-mortise structure that effectively prevents the traction hook 300 from rotating or sliding within the vertical attachment tube when subjected to force. The tenon-and-mortise structure also makes the traction hook 300 more secure in the buccal tube 400 or bracket, maintaining stable performance even in complex oral environments. Its resistance to detachment greatly reduces the possibility of accidents during treatment, providing patients with a more reliable and reassuring treatment experience. Furthermore, the size of the second tenon 120 is smaller than that of the first tenon 110. For example, the width of the second tenon 120 can be smaller than the width of the first tenon 110, which is equivalent to a width reduction design at the end of the first tenon 110. This is intended to provide medical workers with more precise guidance when placing the traction hook 300 into the vertical accessory tube, making it easier to guide the insertion of the traction hook 300, thus making the process of inserting the traction hook into the vertical accessory tube smoother and simplifying the operation.

[0060] Specifically, please refer to Figure 2 The first tenon 110 includes: a first column 111, a first contraction portion 112, and a second contraction portion 113. The first contraction portion 112 extends and contracts from the traction arm 200 toward the first column 111 and is used to connect the traction arm 200 and the first column 111. The second contraction portion 113 extends and contracts from the first column 111 toward the second tenon 120 and is used to connect the first column 111 and the second tenon 120.

[0061] In this embodiment, the first column 111 is tightly fitted with the vertical accessory tube, the traction arm 200 is located on the vertical accessory tube, and the first contraction part 112 is located between the traction arm 200 and the first column 111. The first contraction part 112 can act as a limit, allowing the first column 111 to self-lock onto the vertical accessory tube. At the same time, the first contraction part 112 can avoid stress concentration at the connection position between the first tenon 110 and the traction arm 200, and can strengthen the connection strength between the traction arm 200 and the first tenon 110. The second contraction part 113 can avoid stress concentration at the connection position between the first tenon 110 and the second tenon 120, and can strengthen the connection strength between the first tenon 110 and the second tenon 120.

[0062] Specifically, please refer to Figure 2The first column 111 includes a first plane 114, a second plane 115, a third plane and a fourth plane. The first plane 114, the second plane 115, the third plane and the fourth plane are sequentially closed and connected. Curved surfaces 116 are provided between the first plane 114 and the second plane 115, between the second plane 115 and the third plane, between the third plane and the fourth plane, and between the fourth plane and the first plane 114.

[0063] In this embodiment, the first column 111 includes a first plane 114, a second plane 115, a third plane, and a fourth plane. It can be understood that the first column 111 adopts a cuboid columnar structure; for example, the first column 111 can be made of a square profile. This allows the first column 111 to fit tightly with the vertical attachment tube on the buccal tube 400, constructing a stable tenon-and-mortise structure, effectively preventing the traction hook 300 from rotating or sliding within the vertical attachment tube when subjected to force. The tenon-and-mortise structure also makes the traction hook 300 more secure in the buccal tube 400 or bracket, maintaining stable performance even in complex oral environments. Its resistance to detachment greatly reduces potential accidents during treatment, providing patients with a more reliable and reassuring treatment experience.

[0064] Curved surfaces 116 are provided between the first plane 114 and the second plane 115, between the second plane 115 and the third plane, between the third plane and the fourth plane, and between the fourth plane and the first plane 114. This makes it less likely to scratch the patient's oral mucosa. On the other hand, the structure is more stable and can extend its service life.

[0065] Specifically, please refer to Figure 2 The second tenon 120 includes a second column 121 and a third contraction portion 122. The second column 121 is connected to the second contraction portion 113 of the first tenon 110. The third contraction portion 122 is located at the end of the second column 121 and is formed by contracting outward from the second column.

[0066] In this embodiment, the third contraction portion 122 extends outward from the second column 121, and the second tenon 120 is used to guide the first tenon 110. The third contraction portion 122 is located at the end of the second column 121. The third contraction portion 122 can be understood as the size of the end of the second column 121 gradually decreasing. The third contraction portion 122 can guide the second column 121 to be quickly inserted into the vertical accessory tube. In actual use, the third contraction portion 122 is less likely to scratch the patient's oral mucosa, thereby reducing the possibility of causing oral ulcers.

[0067] The second column 121 can also be made of a square profile, and the corners of the square profile can be connected by a curved surface 116 to avoid scratching the patient's oral mucosa.

[0068] Example 2:

Therefore, this multi-hook cheek tube possesses all the technical features and beneficial effects of the aforementioned insertable long-arm traction hook, which will not be elaborated further.

[0070] In summary, this application discloses an insertable long-arm traction hook and a multi-hook buccal tube. The insertable long-arm traction hook includes a tenon, a traction arm, and at least one traction hook. The tenon is mounted on the buccal tube, and the traction arm is connected to the side of the tenon away from the buccal tube, with a certain angle between the traction arm and the tenon.
