However, it should be noted that the protection scope of the utility model should not be limited to the following implementation, and the person skilled in the art can combine the following implementation to the connection of other types of accessories with the tooth or the shell-shaped corrector 200 according to requirements.

[0058] As shown in Figs. 1 and 2, the accessory is taken as the jaw pad 100, and the accessory is attached to the shell-shaped corrector 200, and the specific implementation is further illustrated. However, it should be noted that the protection scope of the utility model should not be limited to the following implementation, and the person skilled in the art can combine the following implementation to the connection of other types of accessories with the tooth or the shell-shaped corrector 200 according to requirements. Figure 2 As shown in Figs. 1 and 2, the accessory is taken as the jaw pad 100, and the accessory is attached to the shell-shaped corrector 200, and the specific implementation is further illustrated. However, it should be noted that the protection scope of the utility model should not be limited to the following implementation, and the person skilled in the art can combine the following implementation to the connection of other types of accessories with the tooth or the shell-shaped corrector 200 according to requirements.

[0059] As shown in Figs. 1 and 2, the accessory is taken as the jaw pad 100, and the accessory is attached to the shell-shaped corrector 200, and the specific implementation is further illustrated. However, it should be noted that the protection scope of the utility model should not be limited to the following implementation, and the person skilled in the art can combine the following implementation to the connection of other types of accessories with the tooth or the shell-shaped corrector 200 according to requirements. Figure 2As shown, the connecting piece 210 is located directly above the tooth end surface and at the middle region; by setting the connecting groove 110 in the jaw pad 100, the connecting groove 110 can be sleeved on the connecting piece 210, so that the jaw pad 100 is located directly above the tooth end surface to perform corresponding correction.

[0060] The connecting piece 210 has a larger outer diameter at the position with the limiting portion 211 than the rest; the connecting groove 110 has a smaller inner diameter at the position with the matching portion 111 than the rest; the limiting portion 211 is connected to the inside of the connecting groove 110 and beyond the matching portion 111 to be clamped with the limiting portion 211. The limiting portion 211 and the matching portion 111 that realize clamping are formed between the connecting piece 210 and the accessory. During the process that the limiting portion 211 is connected to the inside of the connecting groove 110, the limiting portion 211 can be beyond the matching portion 111, so that the matching portion 111 is clamped between the limiting portion 211 and the tooth end surface, which can realize detachable connection between the connecting piece 210 and the accessory by configuration of the structure shape.

[0061] As shown in the drawings, Figure 2 The limiting portion 211 is a first circumferential protrusion 212 arranged at the position of the connecting piece 210 away from the tooth end surface, and the matching portion 111 is a second circumferential protrusion 112 arranged in the connecting groove 110.

[0062] Specifically, the first circumferential protrusion 212 is protruded outward along the radial direction of the connecting piece 210 at the end of the connecting piece 210 and arranged uninterruptedly along the circumferential direction of the end to form the limiting portion 211 with a larger outer diameter at the end of the connecting piece 210. The second circumferential protrusion 112 is protruded inward along the radial direction of the connecting piece 210 at the inner side wall of the connecting groove 110 and arranged along the circumferential direction of the inner side wall of the connecting groove 110 to form the matching portion 111 with a smaller inner diameter in the connecting groove 110. In other embodiments, the limiting portion 211 can also be arranged intermittently along the outer side wall of the connecting piece 210 as long as a larger outer diameter is formed at the position; correspondingly, the matching portion 111 can also be arranged intermittently along the inner side wall of the connecting groove 110 as long as a smaller inner diameter is formed at the position.

[0063] Further, as shown in the drawings, Figure 2 The first circumferential protrusion 212 is arc transitioned at the end surface of the connecting piece 210 and the junction with other parts of the connecting piece 210; the second circumferential protrusion 112 has an arc-shaped outer contour. Thus, it is beneficial for the connection and disconnection of the connecting piece 210 and the accessory.

[0064] As shown in the drawings, Figure 1As shown, the sidewall of the connecting groove 110 has an opening 120 that extends along the height direction of the teeth. By providing the opening 120 on the sidewall of the connecting groove 110, the accessory can be engaged with the connector 210 by its own deformation when pressed, and the accessory can also be easily removed from the connector 210.

[0065] like Figure 2 As shown, the connector 210 is provided on the shell-shaped orthodontic appliance 200, and is formed by embedding the insert 220 within the shell-shaped orthodontic appliance 200. By providing the insert 220, the structure of the connector 210 can be formed on the shell-shaped orthodontic appliance 200. Furthermore, by configuring the structure of the insert 220, the connector 210 of the desired shape can be obtained, which facilitates manufacturing.

[0066] Example 2

[0067] This embodiment provides an accessory, which is a component that can be attached to teeth or a shell-shaped orthodontic appliance 200. This embodiment provides an accessory that can be detachably connected to teeth or a shell-shaped orthodontic appliance 200. The accessory is used in the orthodontic kit provided in Embodiment 1 above, and can also be used in conjunction with the shell-shaped orthodontic appliance 200 provided in Embodiment 3. The accessory has a mating part 111. Through the mating part 111, the accessory can be connected to or detached from teeth or a shell-shaped orthodontic appliance 200. Therefore, the accessory can be reused. In specific implementations, the accessory is a jaw pad 100, a flat guide plate, an inclined guide plate, or a jaw plate, etc.

[0068] like Figure 3 and Figure 4 As shown, this embodiment takes the jaw pad 100 as an example to specifically illustrate the way in which the attachment is detachably connected to the teeth or the shell-shaped orthodontic appliance 200. However, the attachments in this utility model should not be limited to the jaw pad 100. Those skilled in the art can, according to their needs, set corresponding mating parts 111 on other attachments to achieve detachable connection with the teeth or the shell-shaped orthodontic appliance 200.

[0069] like Figure 1 As shown, when the attachment is a jaw pad 100, the jaw pad 100 extends along the dentition direction of the teeth and covers at least two teeth. In practice, the jaw pad 100 typically covers the posterior tooth region. The upper and lower surfaces of the jaw pad 100 have a concave-convex structure, which is generated based on the morphological design of the upper and lower teeth at its intended installation location. The jaw pad 100 can be manufactured by 3D printing, machining, or molding.

[0070] like Figure 3 and Figure 4 As shown, the jaw pad 100 has a connecting groove 110, and the mating part 111 is disposed in the connecting groove 110.

[0071] like Figure 4As shown, the connecting groove 110 has a smaller inner diameter at the position with the matching part 111 than the rest of the connecting groove 110. Thus, a narrower clamping structure is formed at the matching part 111.

[0072] Preferably, the matching part 111 is a second circumferential protrusion 112 arranged in the connecting groove 110. As shown, Figure 4 As shown, the connecting groove 110 has a substantially uniform inner diameter except for the part of the second circumferential protrusion 112; as shown, Figure 3 As shown, the second circumferential protrusion 112 is arranged circumferentially around the inner side wall of the connecting groove 110.

[0073] As shown, Figure 3 and Figure 4 The connecting groove 110 extends through the height direction of the jaw pad 100. The connecting groove 110 extending through the height direction of the jaw pad 100 is conducive to the clamping between the matching part 111 and the limiting part 211.

[0074] In other embodiments, the connecting groove 110 extends in the height direction of the jaw pad 100 and does not extend through the jaw pad 100. The connecting groove 110 not extending through the jaw pad 100 makes the surface of the jaw pad 100 not extending through have a complete contour, which is conducive to cooperation with the corresponding teeth and treatment.

[0075] In specific implementation, the matching part 111 and the limiting part 211 can be connected by deformation of themselves, so that the circumferential direction of the connecting groove 110 forms a closed side wall.

[0076] In other embodiments, as shown, Figure 3 The connecting groove 110 is provided with an opening 120, which extends through the height direction of the jaw pad 100 at the side wall of the connecting groove 110. The jaw pad 100 can be made of a relatively hard material. By providing the opening 120, the jaw pad 100 can be deformed to facilitate clamping with the limiting part 211 when the jaw pad 100 is pressed, and the jaw pad 100 can be easily pulled off the shell-shaped aligner 200 when the jaw pad 100 is pulled.

[0077] The jaw pad 100 can have one connecting groove 110 or multiple connecting grooves 110. As shown, Figure 1 and 3 The structure of the jaw pad 100 having two connecting grooves 110 is shown. The two connecting grooves 110 are distributed at both ends of the jaw pad 100 and extend through the height direction of the jaw pad 100, and both have openings 120. As shown, Figure 1 The openings 120 of the two connecting grooves 110 can be arranged on the same side of the jaw pad 100 or on different sides of the jaw pad 100.
