[0020] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0021] During the process of orthodontic treatment, the doctor will implant anchor pins in the mouth as a force basis according to the actual situation of the patient, and then connect the anchor pins and the appliance through an elastic tension band, thereby applying tension to the appliance for correction. However, the implantation of anchor pins may cause risks such as infection, inflammation, bleeding, or nerve damage. In order to reduce the risks brought by implanting anchor pins, the present application proposes an invisible braces that can still apply force to specific parts of the teeth to enhance the correction effect without the need for implanting anchor pins.

[0022] Example 1 Reference Figure 1 The present application provides an invisible braces, which includes a braces body and a force-applying unit 3 installed on the braces body. The force-applying unit 3 can pull a specific position of the braces body, thereby correcting the internal teeth through the braces body.

[0023] Specifically, the orthodontic appliance body includes a fitting portion 1 and a fitting portion 2. The fitting portion 1 is arc-shaped and adapted to fit the teeth. A first connecting member 11 is provided on one side wall of the fitting portion 1 along the front-to-back direction. The fitting portion 1 is provided with a wearing opening extending along its length. Taking the direction of the wearing mouth opening as the first direction, the fitting part 2 is arranged on the side of the fitting part 1 facing the first direction and is connected to the inner arc surface of the fitting part 1. The fitting part 2 is plate-shaped, and the side of the fitting part 2 is away from the inner arc surface of the fitting part 1. The side of the fitting part 2 facing the first direction forms a fitting surface, which is used to fit tightly against the inside of the oral cavity.

[0024] The force applying unit 3 includes a second connecting member 31 and a force applying member 32 . The second connecting member 31 is installed on the side of the fitting portion 2 away from the first direction. One end of the force applying member 32 is elastically connected to the first connecting member 11 , and the other end is elastically connected to the second connecting member 31 .

[0025] From the above, it can be seen that when wearing the invisible braces of the present application, the force-applying member 32 is first connected to the first connecting member 11 and the second connecting member 31, and then the braces body is installed in the oral cavity until the wearing mouth fits on the teeth. At this time, through the elastic connection between the force-applying member 32 and the first connecting member 11, a pulling force is given to the first connecting member 11 toward the second connecting member 31, thereby pulling the fitting portion 1 at the first connecting member 11 and then applying force to the internal teeth to achieve tooth correction. This method provides an installation basis for the second connecting member 31 that replaces the support pin by adding a fitting portion 2 that fits inside the oral cavity to the existing invisible braces, thereby reducing the implantation of the support pins and thus avoiding inflammation and infection at the implantation position in the oral cavity. At the same time, it can provide a stable pulling force for the first connecting member 11, thereby improving the effect of the braces. At the same time, the force-applying unit 3 is completely set on the invisible braces, which is convenient for all components to be completely disassembled from the oral cavity, and convenient for cleaning, maintenance or replacement.

[0026] In particular, existing invisible braces require brushing and cleaning before wearing, and some orthodontic patients may reduce the time they wear invisible braces during normal work and life during the day in pursuit of beauty, and wear them at night. After wearing the invisible braces in this application, the fitting part 2 is tightly attached to the oral cavity. At night and when sleeping, the tongue can fit tightly to the fitting part 2 and work together with the inner wall of the oral cavity to clamp the fitting part 2, thereby providing a solid force basis for the force-applying member 32. Compared with the existing invisible braces, this application adds a force-applying member 32, which can make up for the lack of wearing time by increasing the correction force at night, thereby improving the correction effect.

[0027] In this embodiment, the fitting part 2 and the fitting part 1 are integrally formed to form the orthodontic appliance body, wherein the hardness of the fitting part 2 is greater than the hardness of the fitting part 1. After the orthodontic appliance body is completed as a whole, the fitting part 2 is subjected to secondary processing separately so that the hardness of this part is greater than the hardness of the fitting part 1. Through this design, when the force-applying unit 3 applies force to both ends at the same time, the fitting part 2 with higher hardness is less likely to deform than the fitting part 1 with lower hardness, thereby making the fitting part 1 better deformable, and then being able to apply force to correct the teeth.

[0028] In this embodiment, the first connecting member 11 is an accessory or a traction hook, which is not specifically limited in this embodiment. The first connecting member 11 can be directly integrally formed with the fitting part 1 of the invisible braces through photocurable resin 4 or according to three-dimensional modeling during production, thereby achieving the fixation of the first connecting member 11 and the invisible braces.

[0029] As a further embodiment, the second connecting member 31 can be detachably installed on the fitting portion 2. During use, the attending physician can adjust and install the position of the second connecting member 31 according to the angle and position of force required, so as to better adjust the force member 32 and improve the wearing comfort of orthodontic patients.

[0030] Specifically, the second connecting member 31 includes a connecting box 33 and a hook 34. The connecting box 33 is connected to the fitting part 2. A plurality of connecting holes are provided on the side wall of the connecting box 33 at one end facing away from the fitting part 2. The hook 34 is installed at any one of the connecting holes, and the force applying member 32 is hung on the hook 34. As can be seen from the above, by pre-setting the connecting box 33 with a plurality of linking holes, the hook 34 can be adjusted at multiple angles by simply installing the hook 34 at any one of the connecting holes according to actual needs, and then the connecting box 33 is directly cured onto the fitting part 2 by the photocurable resin 4 to achieve a stable connection between it and the fitting part 2.

[0031] Through the above scheme, it can be seen from the overall detachable feature of the second connecting member 31 that when it is necessary to adjust the correction plan or change the correction stage, not only the position of the hook 34 can be replaced, but the second connecting member 31 can also be disassembled as a whole and reinstalled at other positions of the fitting part 2, further expanding the scope of application and flexibility of the orthodontic appliance. At the same time, hooks 34 can be installed separately in multiple connecting holes, thereby increasing the correction angle of the teeth.

[0032] As a further embodiment, a protective gasket is provided on the connecting box body 33. The protective gasket can be made of soft silicone material. The protective gasket is then fixed to the fitting part 2 by light-curing resin 4 and completely covers the connecting box body 33. Only the hook part of the hook 34 is exposed to facilitate connection with the force-applying member 32, thereby reducing the collision between the tongue and the hard second connecting member 31 and causing damage to the tongue.

[0033] In this embodiment, the force-applying member 32 is an elastic band or a chain-like rubber band. Both the elastic band and the chain-like rubber band are made of elastic material and can continuously release elastic force under tension, thereby providing a stable and gentle corrective force for tooth movement. In clinical practice, elastic bands and chain-like rubber bands have a variety of specifications. Doctors can flexibly select a suitable force-applying member 32 according to the patient's degree of tooth misalignment, movement direction, and correction stage, thereby realizing a personalized correction plan and improving the correction effect.

[0034] The implementation principle of Example 1 of the present application is: after the orthodontic patient wears the invisible braces, the tongue presses against the fitting part 2 and works together with the inner wall of the oral cavity to clamp the fitting part 2, and then the force-applying member 32 applies force to the fitting part 1 of this part through the first connecting member 11, thereby correcting the teeth of this part.

[0035] Example 2 The difference between Example 2 of the present application and Example 1 is that, referring to Figure 2 、 Figure 3 and Figure 4 The second connecting member 31 also includes a mounting box 35, which can be detachably mounted on the fitting portion 2. The connecting box 33 is mounted on a side of the mounting box 35 away from the fitting portion 2. The connecting box 33 is provided with a sliding groove 351, and a sliding rod 36 is installed in the sliding groove 351. The sliding rod 36 can slide and position in the mounting box 35 toward or away from the fitting portion 2. The sliding rod 36 is connected to one end of the hook 34 installed in the connecting box 33.

[0036] When installing the second connecting member 31, the installation box 35 and the connecting box 33 are connected to each other, and then the hook 34 is installed on the connecting box 33. Then the attending physician uses light curing to cure the installation box 35 and the connecting box 33 connected as a whole on the bonding part 2.

[0037] An elastic member 37 is provided in the sliding groove 351. In the present embodiment, the elastic member 37 is a spring. One end of the elastic member 37 is sleeved and connected to the sliding rod 36, and the other end is connected to the bottom groove wall of the sliding groove 351. When the elastic member 37 is in a natural state, the sliding rod 36 moves toward the direction close to the fitting portion 2. As can be seen from the above, after the second connecting member 31 is fixed on the fitting portion 2, the elastic member 37 pulls the sliding rod 36 toward the direction close to the fitting portion 2, that is, moves in the direction away from the first connecting member 11, driving the first connecting member 11 to pull the fitting portion 1 to move, thereby realizing orthodontic treatment. At this time, the elastic member 37 can drive the force-applying member 32 by pulling the sliding rod 36, thereby increasing the effect of the pulling force on the first connecting member 11.

[0038] Under long-term wearing, the force-applying member 32 keeps pulling the elastic member 37 through the sliding rod 36. As time goes by, the deformation degree of the elastic member 37 on the sliding rod 36 gradually decreases, and the elastic force gradually decreases. In order to maintain the elastic force of the elastic member 37 and increase the pulling degree of the elastic member 37 on the force-applying member 32 during use, refer to Figure 4 The tongue 37 is pressed against the tongue top plate 38, thereby squeezing the sliding rod 36 toward the bonding portion 2 and the second connecting member 31 on the bonding portion 2. At the same time, one end of the elastic member 37 connected to the sliding rod 36 is synchronously moved toward the bonding portion 2, that is, the end of the elastic member 37 is close to the other end, causing the elastic member 37 to be compressed. At this time, the tongue not only replaces the use of the elastic member 37, but also restores the elastic potential energy of the elastic member 37 through its compression of the elastic member 37. During daytime use, when the tongue cannot continuously press the sliding rod 36, the elastic member 37 compensates for the action and pulls the force-applying member 32, thereby achieving correction of the teeth at the bonding portion 1.

[0039] As a further embodiment, a limit groove 352 extending along the first direction is provided on the groove wall of the installation groove, and a limit block 39 is provided on the sliding rod 36. The limit block 39 is located in the limit groove 352. The limit block 39 can move with the sliding rod 36 to abut against the groove wall at any end of the limit groove 352 along the first direction, thereby limiting the sliding rod 36 at this time, preventing the force-applying member 32 from being pulled excessively, causing over-correction or under-correction.

[0040] The hook 34 extends horizontally on the connecting box 33 and perpendicular to the first direction. The section of the hook 34 in the connecting box 33 is connected to a pull rope 341, and the pull rope 341 is connected to the sliding rod 36. In order to prevent the hook 34 from detaching, the hook 34 needs to be placed in the horizontal direction, and then the hook 34 and the sliding rod 36 are connected by the pull rope 341, so that the sliding rod 36 can always drive the hook 34 to move through the pull rope 341 after being squeezed.

[0041] As a further embodiment, chamfers are provided at the intersection of the sides of the connecting box 33 and the mounting box 35 to reduce the sharpness of the connecting box 33 and the mounting box 35 and reduce damage to the oral cavity of the orthodontic patient.

[0042] The connecting box 33 is covered with a protective gasket (not shown in the drawings), and the end of the sliding rod 36 passing through the connecting box 33 is located on the side of the protective gasket away from the fitting part 2. The protective gasket is bonded to the fitting part 2 by the light-curing resin 4, thereby completely covering the connecting box 33 and the installation box 35. The side of the protective gasket away from the second connecting piece 31 can be adapted to the tongue of the orthodontic patient, thereby improving the comfort when wearing.

[0043] The implementation principle of Example 2 of the present application is: when an orthodontic patient wears the invisible braces of the present application and closes his mouth, the tongue abuts against the fitting part 2, thereby pressing the fitting part 2 tightly in the mouth, providing a stable basis for the force-applying member 32 to pull the first connecting member 11. At the same time, the tongue will abut against the tongue top plate 38, squeezing the sliding rod 36, so that the sliding rod 36 drives the elastic member 37 to be compressed, and at the same time replaces the function of the elastic member 37, driving the sliding rod 36 to move and further pulling the hook 34 to pull the force-applying member 32, thereby improving the therapeutic effect of the invisible braces.

[0044] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
