Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dental orthodontic traction hooks, in particular to an improved adhesive S-shaped long-arm traction hook for invisible orthodontics. Background Art
[0002] Dental orthodontic traction hooks generate traction force on teeth through rubber bands, causing displacement and angular changes of teeth.
[0003] 1. For orthodontic patients undergoing tooth extraction for orthodontics clinically, during the process of closing the space, the existing long-arm traction hook is a question mark hook, and the rubber band easily slides on the hook body to the bottom of the traction hook, resulting in a change in the traction force direction, thereby causing the crowns of the teeth on both sides of the space to incline towards the space side.
[0004] 2. For patients with mesial inclination of the first molar clinically, the existing tongue buckle has a short force arm. Due to the lever principle, the force applied to the normal teeth in the opposing jaw when uprighting the first molar is relatively large.
[0005] 3. For invisible orthodontic patients with mesial inclination of the first molar, due to the lack of adhesive long-arm traction hooks clinically, it is often necessary to cut off the rear section of the dental appliance and use sectional arch technology to assist in uprighting the molar, which affects the orthodontic effect and progress.
[0006] 4. The rubber band easily slides on the traditional "C"-shaped traction hook, affecting the correction effect.
[0007] Therefore, it is necessary to provide an improved adhesive S-shaped long-arm traction hook for invisible orthodontics to solve the above technical problems. Content of the Utility Model
[0008] To solve the above technical problems, the utility model provides an improved adhesive S-shaped long-arm traction hook for invisible orthodontics.
[0009] An improved adhesive S-shaped long-arm traction hook for invisible orthodontics provided by the utility model includes a metal tongue buckle and an S-shaped long-arm traction hook. The metal tongue buckle includes an adhesive part for fixing on the side wall of the tooth, a hanging part arranged on one side of the adhesive part for hanging the rubber band, and an anti-disengagement part arranged at the end of the hanging part far away from the adhesive part for preventing the rubber band from disengaging from the hanging part. The adhesive part, the hanging part, and the anti-disengagement part are of an integral structure. The side wall of the hanging part is welded and fixed with the S-shaped long-arm traction hook. The S-shaped long-arm traction hook includes a traction hook arm made of stainless steel square wire fixed to the hanging part and an S-shaped hook formed by bending the square wire integrally arranged at the end of the traction hook arm for hanging the rubber band.
[0010] Preferably, the side of the adhesive part facing away from the hanging part is a concave surface and is provided with a mesh protrusion.
[0011] Preferably, the bonding part, the anti - detachment part and the S - shaped hook are parallel to each other. The bonding part and the anti - detachment part are both circular. The extension line of the traction hook arm is perpendicular to and intersects with the rotation center line of the bonding part and the anti - detachment part.
[0012] Preferably, a fillet is provided at the connection between the S - shaped hook and the traction hook arm.
[0013] Preferably, the length of the traction hook arm is 8 mm, the diameter of the bonding part is 3 mm, the diameter of the anti - detachment part is 2 mm, the diameter of the suspension part is 1 mm, and the width and height of the square wire are 0.017×0.025 inches.
[0014] Preferably, the outer edge of the anti - detachment part is arc - shaped.
[0015] Compared with the related technology, the present utility model has the following beneficial effects:
[0016] 1. Using an 8 - mm long - arm traction hook, the force - application point is closer to the impedance center of the tooth when closing the gap (the impedance center is on the tooth long axis, approximately at 1 / 3 - 1 / 4 of the root length near the alveolar ridge end).
[0017] 2. The long - arm traction hook increases the force arm and reduces the force applied to the normal teeth of the opposing jaw when uprighting the first molar.
[0018] 3. This traction hook is simple to manufacture, inexpensive, and easy for patients to accept.
[0019] 4. The end has an additional bend compared with the commonly used clinical traction hook, which can fix the rubber band within the circular bend at the S - shaped end and prevent it from sliding to the bottom.
[0020] 5. When wearing braces during invisible orthodontics, an avoidance notch can be designed at the brace part where the traction hook needs to be bonded, enabling the force application of the traction hook to be carried out simultaneously with invisible orthodontics, which is different from the traditional sectional arch technology.

[0030] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] Please refer to Figures 1 to 5 , an improved bonded S-shaped long arm traction hook for invisible orthodontics, including a metal tongue buckle 2 and an S-shaped long arm traction hook 6. This metal tongue buckle 2 ingeniously integrates three main parts: a bonding part 3 for firmly fixing on the side wall of the tooth; a hanging part 4 provided on one side of the bonding part 3, specifically for hanging rubber bands; and an anti-detachment part 5 located at the end of the hanging part 4 away from the bonding part 3, effectively preventing the rubber band from detaching from the hanging part 4. The bonding part 3, the hanging part 4 and the anti-detachment part 5 adopt an integrated design, which not only has a stable structure but also greatly facilitates the processing and manufacturing process.
[0032] On the side of the bonding part 3 facing away from the hanging part 4, it is a concave surface and is specially designed with a mesh protrusion 9. This ingenious idea can make it more conform to the tooth surface when using glue to bond the bonding part 3 to the tooth, significantly improving the bonding effect and ensuring the stability of the traction hook.
[0033] The side wall of the hanging part 4 is fixedly connected to the S-shaped long arm traction hook 6 by welding. This S-shaped long arm traction hook 6 consists of two parts: a traction hook arm 7, which is made of square wire and is closely connected to the hanging part 4; and an S-shaped hook 8, which is located at the end of the traction hook arm 7 and is also bent from square wire, specifically for hanging rubber bands. It is worth mentioning that the S-shaped long arm traction hook 6 is carefully made of stainless steel square wire with a width and height of 0.017×0.025 inches. The length of the traction hook arm 7 is 8 mm, and the part of the S-shaped hook 8 actually used for hanging the rubber band is located at the end away from the traction hook arm 7.
[0034] In the design, the bonding part 3, the anti - detachment part 5, and the S - shaped hook 8 all maintain a parallel relationship with each other. At the same time, both the bonding part 3 and the anti - detachment part 5 are circular. The extension line of the traction hook arm 7 is perpendicular to and intersects the rotation center lines of the bonding part 3 and the anti - detachment part 5. Such a design enables the welding part of the traction hook arm 7 and the suspension part 4 to be more stable when the traction hook arm 7 is pulled by a rubber band, thus ensuring the durability and reliability of the entire traction hook.
[0035] A chamfered corner 1 is provided at the connection between the S - shaped hook 8 and the traction hook arm 7. In this way, when it comes into contact with the skin inside the mouth, there will be no sharp edges, thus effectively preventing scratching of the skin inside the mouth.
[0036] In terms of dimension design, the diameter of the bonding part 3 is 3 mm, the diameter of the anti - detachment part 5 is 2 mm, and the diameter of the suspension part 4 is 1 mm. Such a dimension configuration not only ensures the structural stability but also effectively prevents the rubber band hanging on the side wall of the anti - detachment part 5 from falling off.
[0037] The outer edge of the anti - detachment part 5 is arc - shaped. When it comes into contact with the skin inside the mouth, there are no sharp edges, preventing scratching of the skin inside the mouth.
[0038] It should be emphasized that: there are two orientations of the S - shaped hook 8 relative to the metal tongue buckle 2, as Figure 5 and Figure 6 shown.
[0039] Clinical application:
[0040] 1. For orthodontic patients undergoing tooth extraction and orthodontic treatment clinically, during the process of closing the space, wearing a rubber band after bonding an S - shaped long - arm traction hook on the labial surfaces of the teeth on both sides of the extraction space can effectively accelerate the space closure, as Figure 7 shown.
[0041] 2. For invisible orthodontic patients with the premature loss of the second primary molar resulting in the mesial inclination of the first molar, an S - shaped long - arm traction hook can be bonded at the mesial position on the buccal side, and a tongue buckle can be bonded at the appropriate tooth position of the opposing jaw or a corresponding device can be designed on the orthodontic appliance, and then wear a rubber band to correct the mesial inclination of the first molar and make it upright, as Figure 8 shown.
[0042] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present utility model.
