[0002] When using invisible braces for tooth extraction correction, traditional braces are usually designed with accessories to provide torque to assist in the overall movement of the teeth. However, the accessories are generally short in length. At the same time, in order for the invisible braces to be smoothly positioned, the thickness of the accessories cannot be too large, and their edges are relatively rounded and blunt. For example, patent CN202320044726.X discloses an orthodontic accessory template, which provides a protruding structure on the braces and an accessory that cooperates with the protruding structure on the teeth to assist in the overall movement of the teeth. However, the accessories are small, and ultimately the torque provided to the braces is limited, and cannot effectively assist in the overall movement of the teeth. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a correction structure in which a dental brace is closely fitted to teeth, thereby facilitating the overall movement of teeth.

[0004] In order to achieve the above-mentioned purpose, the technical solution proposed by the utility model is: a correction structure that is conducive to the overall movement of teeth, including invisible correction braces, buccal attachments, lingual attachments and elastic elements; the invisible correction braces are covered on the dentition; the buccal attachments are bonded to the buccal side of the teeth, and one end extends toward the gum and is exposed from the edge of the invisible correction braces to form a traction part; the lingual attachment is bonded to the lingual side of the teeth, and is provided with a traction hook extending toward the gum; the elastic element is connected to the traction part and then bypasses the incisal edge of the invisible correction braces to connect with the traction hook; thereby, the elastic element is used to compress the invisible correction braces, so that the invisible correction braces fit closely with the teeth, which is conducive to the overall movement of the teeth.

[0005] A further design of the above technical solution is as follows: the invisible orthodontic braces are provided with a protruding placement groove at a position corresponding to the buccal attachment, and the buccal attachment is arranged in the placement groove and fits with the inner wall of the placement groove.

[0006] A gap is provided between the traction portion of the buccal attachment and the gums.

[0007] The buccal attachment is rectangular and is arranged on the teeth with the length direction perpendicular to the dentition direction.

[0008] The lingual attachment is provided with a bonding portion for bonding to the teeth, the traction hook is fixed on the bonding portion, and the traction hook is exposed on the gingival side of the invisible correction brace edge.

[0009] The elastic element is a rubber rope, which is ring-shaped. Two sides of the rubber rope are respectively sleeved on the traction part and the traction hook, and two sides of the middle of the rubber rope are respectively wound around the boundaries of adjacent teeth of the invisible correction braces.

[0010] The buccal attachment traction portion is provided with a connecting hook, and the corresponding connecting hooks on the two teeth are connected through a traction element.

[0011] The beneficial effects of the utility model are:

[0012] The utility model is provided with a buccal attachment and a lingual attachment which cooperate with the invisible braces, the buccal attachment and the lingual attachment are extended out of the gingival side of the invisible braces, and then the buccal attachment and the lingual attachment are connected by an elastic element, thereby generating a force for the invisible braces to approach the teeth, so that the invisible braces are closely fitted to the teeth, which is beneficial to the overall movement of the teeth during the correction of the teeth.

[0013] The invisible orthodontic braces of the utility model are provided with placement grooves at positions corresponding to the buccal attachments. The placement grooves are closely fitted with the buccal attachments to generate a large torque. During correction, the invisible orthodontic braces and the buccal attachments are not prone to relative sliding, and the force can be basically completely transmitted to the teeth, which is conducive to the overall movement of the teeth.

[0023] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0024] like Figure 1 and Figure 2 As shown, the correction structure of this embodiment that is beneficial to the overall movement of teeth includes an invisible correction brace 1, a buccal attachment 2, a lingual attachment 3 and an elastic element 4, wherein the invisible correction brace 1 is covered on the dentition.

[0025] Combination Figure 3 As shown, the buccal attachment 2 is bonded to the buccal side of the tooth 5, the invisible orthodontic brace 1 covers the buccal attachment 2, one end of the buccal attachment 2 extends toward the gum and is exposed from the edge of the invisible orthodontic brace 1 to form a traction portion 21; the buccal attachment 2 is rectangular as a whole and is bonded to the tooth with its length direction perpendicular to the dentition direction; the body of the buccal attachment 2 is bonded to the tooth 5, and the traction portion 21 is bent outward and extends toward the gum, so that a gap 22 is formed between the traction portion 21 and the gum 6 for connection with the rubber rope.

[0026] Combination Figure 4 The lingual attachment 3 shown is bonded to the lingual side of the tooth, the invisible braces 1 covers the lingual attachment 3, the lingual attachment 3 is provided with a traction hook 31 extending toward the gum, the lingual attachment 3 is provided with a bonding portion 31 for bonding to the tooth, the bonding portion 31 is in a spherical shape, which is convenient for fitting with the invisible braces 1, the traction hook 32 is fixed on the bonding portion 31, and the traction hook 31 is exposed on the gum side of the invisible braces 1, and is used to be connected with the rubber rope.

[0027] In this embodiment, the elastic element is a rubber rope 4, which is connected to the traction part 21 and then passes around the cutting edge of the invisible braces 1 to be connected to the traction hook 32; thereby, under the elastic force of the rubber rope 4, the invisible braces 1 are pressed toward the teeth, so that the invisible braces 1 fits tightly to the teeth and is not easy to separate, which is conducive to the full positioning of the teeth and the overall movement of the teeth during tooth correction. Embodiment 2

[0028] The correction structure of this embodiment is basically the same as that of the first embodiment, except that: Figure 5 and Figure 6As shown, in this embodiment, the invisible orthodontic braces 1 are provided with a protruding placement groove 11 at a position corresponding to the buccal attachment 2, and the buccal attachment 2 is arranged in the placement groove 11 and fits with the inner wall of the placement groove 11, thereby further enhancing the fit effect between the invisible orthodontic braces 1 and the teeth, and relative sliding is not easy to occur between the rectangular buccal attachment 2 and the placement groove 11, so the placement groove 11 can be used to increase the torque applied to the invisible orthodontic braces 1, which is beneficial to assist in achieving the overall movement of the teeth. Embodiment 3

[0029] The correction structure of this embodiment is basically the same as that of the first embodiment, except that: Figure 1 and Figure 2 As shown, in this embodiment, the rubber cord 4 is in a ring shape, and the two sides of the rubber cord 4 are respectively sleeved on the traction part 21 and the traction hook 32, and the two sides of the middle of the rubber cord 4 are respectively wrapped around the boundary between the adjacent teeth of the invisible braces. Since the invisible braces 1 are recessed at this place, the rubber cord 4 is wrapped around this place to improve the stability of the rubber cord and further improve the fitting effect between the invisible braces 1 and the teeth. In this embodiment, the buccal attachment 2 and the lingual attachment 3 that cooperate with each other can be set on the same tooth or on different teeth. When they are set on different teeth, after the rubber cord 4 connects the buccal attachment 2 and the lingual attachment 3, the span of the rubber cord 4 can be increased, and the force application range of the invisible braces 1 can be increased, thereby achieving the force application on the entire dentition range of the invisible braces 1 under the premise of using less rubber cords. Embodiment 4

[0030] The correction structure of this embodiment is basically the same as that of the first embodiment, except that: Figure 7 and Figure 8 As shown, in this embodiment, a connecting hook 211 is provided at the gingival end of the traction portion 21 of the buccal attachment 2. Because the end of the traction portion 21 is close to the impedance center, traction is beneficial to the overall movement of the tooth. Therefore, a buccal attachment 2 with the same structure is provided on the first molar (or other teeth). Then, the connecting hook 211 of the buccal attachment 2 is connected to the connecting hook 211 on the tooth to be pulled through a traction element 7 such as a rubber band to assist in force application. Such synergistic effect is beneficial to tooth correction.

[0031] The present invention is not limited to the above-mentioned embodiments, and all technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present invention.
