[0032] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all included in the protection scope of the present invention.

[0033] Combination Figures 1 to 7 , which is a schematic diagram of a dental assembly 200 according to an embodiment of the present invention.

[0034] The dental assembly 200 includes an orthodontic appliance 100 , a mounting portion 10 connected to the orthodontic appliance 100 , and a first attachment 20 mounted on the mounting portion 10 .

[0035] Here, the orthodontic appliance 100 refers to a shell-shaped dental device having a cavity for accommodating teeth, and the orthodontic appliance 100 has a mounting surface 101 .

[0036] The assembly portion 10 is fixedly connected to the installation surface 101 , or the assembly portion 10 is detachably connected to the installation surface 101 .

[0037] Specifically, in the present embodiment, the mounting surface 101 is located on the buccal surface A1 of the orthodontic appliance 100, the mounting surface 101 is a flat plane, and the assembly portion 10 is bonded to the mounting surface 101, but is not limited thereto, the mounting surface 101 may also be located on the lingual surface A3 of the orthodontic appliance 100, etc.

[0038] The mounting portion 10 includes a mounting buckle 11 , and the relative position between the mounting portion 10 and the first accessory 20 is configured to be adjustable.

[0039] Here, "the relative position between the assembly part 10 and the first accessory 20 is configured to be adjustable" means that when the first accessory 20 is assembled to the assembly part 10, the relative position between the first accessory 20 and the assembly part 10 can be selected according to actual needs, that is, the relative position between the assembly part 10 and the first accessory 20 is adjustable.

[0040] In this embodiment, the assembly part 10 is provided to improve the assembly freedom of the first accessory 20. Specifically, the assembly part 10 is a universal assembly part. By changing the relative position between the assembly part 10 and the first accessory 20, the first accessory 20 can be placed in different working forms to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0041] Here, multiple first accessories 20 that are in different relative positions to the assembly part 10 can be the same first accessory 20, that is, the correction needs can be met by changing the relative position of the first accessory 20 and the assembly part 10 without changing the accessory type, which can greatly improve the versatility of the first accessory 20.

[0042] Of course, when this type of first accessory 20 cannot meet the correction requirements, while changing the relative position of the assembly portion 10 and the first accessory 20, the type of the first accessory 20 can also be changed to adapt to more application scenarios.

[0043] In this embodiment, combined with Figure 6 The dental component 200 further includes a second accessory 30 , which is assembled at the mounting buckle 11 .

[0044] In addition, combined Figure 7 The dental component 200 further includes a third accessory 40 , and the assembly portion 10 further includes an auxiliary interface 102 , and the auxiliary structure 102 is used for assembling the third accessory 40 .

[0045] That is to say, the assembly part 10 can be selectively connected to at least two types of accessories, which further improves the versatility of the assembly part 10, and different types of accessories can adapt to different application scenarios, which can improve the overall versatility of the dental component 200. In addition, different types of accessories can be used in combination to improve the correction efficiency.

[0046] The first accessory 20 , the second accessory 30 , and the third accessory 40 are at least one of a traction hook, an archwire, a rubber band, and a jaw pad, respectively, but are not limited thereto.

[0047] Here, archwires refer to products with archwires, such as products formed by the combination of an archwire and an extraoral bow, a lip stopper, a palate bead trainer, etc.

[0048] In this embodiment, the assembly part 10 and the first accessory 20 in different relative positions correspond to the same correction step or different correction steps. For example, in the same correction step, the position of the first accessory 20 relative to the assembly part 10 can be adjusted at different time periods to adjust the correction effect, or, in different correction steps, the position of the first accessory 20 relative to the assembly part 10 can be adjusted to match the correction requirements of different correction steps.

[0049] In this embodiment, the relative position between the assembly portion 10 and the first accessory 20 includes at least one of a first relative position in the first direction B1, a second relative position in the second direction B2, a third relative position in the third direction B3, and a relative angle in the first plane C1, wherein the first direction B1 is perpendicular to the buccal surface A1, the second direction B2 is perpendicular to the occlusal surface A2, the third direction B3 is the mesiodistal direction, and the first plane C1 is parallel to the buccal surface A1.

[0050] That is to say, the relative position of the assembly part 10 and the first accessory 20 can be adjusted in the up and down, left and right, front and back directions, or the relative position of the assembly part 10 and the first accessory 20 refers to the relative angle between the two in the first plane C1, and the relative position of the assembly part 10 and the first accessory 20 is adjusted by rotating the first accessory 20 in the first plane C1.

[0051] Several embodiments of the dental assembly 200 are described below.

[0052] Combination Figures 1 to 7 , which is a schematic diagram of a dental component 200 according to a first embodiment.

[0053] In the first embodiment, the dental assembly 200 includes a mounting portion 10 fixedly connected to the orthodontic appliance 100 and a first accessory 20 mounted on the mounting portion 10 , wherein the first accessory 20 is a traction hook as an example.

[0054] The traction hook includes a base portion 201 and a hook portion 202 , and the base portion 201 is assembled on the assembly portion 10 .

[0055] The assembly part 10 also includes a base 12 connecting the orthodontic appliance 100 and the mounting buckle 11, the base 12 includes an outer peripheral wall 121, the first accessory 20 (base 201) includes an edge portion 21 corresponding to the base 12, the edge portion 21 includes an inner wall 211, and when the inner wall 211 and the outer peripheral wall 121 are in different mating positions, different relative angles are formed between the assembly part 10 and the first accessory 20.

[0056] Here, when the inner wall 211 and the outer peripheral wall 121 are in different mating positions (i.e., the base 201 and the assembly portion 10 are in different relative positions), the assembly portion 10 and the first accessory 20 form different relative angles so that the first accessory 20 has multiple working forms, i.e., the hook portion 202 of the first accessory 20 at this time has different extension directions to provide different forms of traction.

[0057] Specific, combined Figure 2 When the inner wall 211 and the outer peripheral wall 121 are in the first mating position, the first accessory 20 extends downward, that is, the hook portion 202 extends downward, and the relative angle between the assembly portion 10 and the first accessory 20 is defined as 0° at this time.

[0058] Combination Figure 3 After the first accessory 20 is rotated, the inner wall 211 and the outer peripheral wall 121 are in the second matching position, and the first accessory 20 extends toward the lower right corner, that is, the hook portion 202 extends toward the lower right corner. At this time, the relative angle between the assembly portion 10 and the first accessory 20 is defined as 30°, that is, the first accessory 20 is rotated 30° relative to the assembly portion 10.

[0059] It can be seen that when the matching position between the inner wall 211 and the outer peripheral wall 121 changes, the relative angle between the assembly portion 10 and the first accessory 20 also changes, thereby changing the extension direction of the hook portion 202. The hook portion 202 with different extension directions can adapt to different traction forces to form different working forms.

[0060] In this embodiment, the peripheral wall 121 includes a plane or a curved surface. In this embodiment, the peripheral wall 121 is formed by splicing six planes as an example, and the cross-section of the peripheral wall 121 is a hexagon, but it is not limited to this. The cross-section of the peripheral wall 121 can also be other polygons, or the peripheral wall 121 is formed by splicing multiple curved surfaces, or the peripheral wall 121 is formed by splicing curved surfaces and planes.

[0061] The inner wall 211 includes two planes parallel to each other.

[0062] The inner wall 211 and the outer wall 121 are configured such that when the inner wall 211 and the outer wall 121 are in a certain matching position, the inner wall 211 and the outer wall 121 match to restrict the first accessory 20 from rotating relative to the base 12 in the first plane C1 .

[0063] That is, after the matching position between the inner wall 211 and the outer wall 121 is determined according to the correction requirements, the inner wall 211 and the outer wall 121 are in planar contact to limit the first accessory 20 from rotating relative to the base 12 within the first plane C1.

[0064] In this embodiment, the first accessory 20 (base 201 ) further includes a central portion 22 connected to the edge portion 21 . The central portion 22 includes a notch 221 . The notch 221 and the mounting buckle 11 are engaged with each other.

[0065] The mounting buckle 11 is located on a side surface of the base 12 away from the orthodontic appliance 100 .

[0066] In this embodiment, the assembly portion 10 and the first accessory 20 are configured as follows: when the first accessory 20 is assembled, the edge portion 21 is engaged with the base 12, and at the same time, the center portion 22 is engaged with the mounting buckle 11 to limit the relative movement of the assembly portion 10 and the first accessory 20 in the first plane C1 and the first direction B1.

[0067] At this time, the first accessory 20 is completely fixed to the mounting portion 10 , and the first accessory 20 can provide stable traction.

[0068] Specifically, the edge portion 21 includes two sub-edge portions 212 vertically arranged on opposite sides of the center portion 22, and an opening P is formed between the two sub-edge portions 212. The direction of the opening P is consistent with the direction of the notch 221, so that the edge portion 21 and the center portion 22 are assembled to the base 12 and the mounting buckle 11 at the same time.

[0069] That is to say, when the first accessory 20 is inserted from the side of the assembly portion 10, the edge portion 21 is plugged into the outside of the base 12 from the side through the opening P, and at the same time, the center portion 22 is plugged into the mounting buckle 11 from the side through the notch 221. After being plugged into place, the inner wall 211 of the edge portion 21 and the outer peripheral wall 121 of the base 12 abut against each other and the mounting buckle 11 restricts the center portion 22, thereby restricting the relative movement of the assembly portion 10 and the first accessory 20 in the first plane C1 and the first direction B1.

[0070] It is understandable that due to the complete symmetry of the mounting buckle 11, the angle at which the notch 221 is inserted into the mounting buckle 11 from the side is not limited. When assembling the first accessory 20 by inserting from the side, only the matching position between the inner wall 211 and the outer peripheral wall 121 needs to be considered, which simplifies the assembly difficulty.

[0071] In this embodiment, the notch 221 includes a connected channel 2211 and a limiting hole 2212 , the mounting buckle 11 includes a rod-shaped portion 111 connected to the base 12 and an umbrella-shaped portion 112 connected to the rod-shaped portion 111 , and the rod-shaped portion 111 passes through the channel 2211 and is limited in the limiting hole 2212 .

[0072] Specifically, the caliber of the channel 2211 is smaller than the diameter of the rod-shaped portion 111, and the caliber of the limiting hole 2212 is roughly equal to the diameter of the rod-shaped portion 111. When the central portion 22 is inserted into the mounting buckle 11 from the side through the notch 221, the rod-shaped portion 111 of the mounting buckle 11 squeezes the channel 2211 to deform it. After the rod-shaped portion 111 enters the limiting hole 2212, the channel 2211 is reset to prevent the rod-shaped portion 111 from escaping from the limiting hole 2212 from one side of the channel 2211. At this time, the rod-shaped portion 111 is limited in the limiting hole 2212 to further limit the relative movement of the assembly portion 10 and the first accessory 20 in the first plane C1.

[0073] In addition, the distance between the umbrella-shaped portion 112 and the base 12 is roughly equal to the thickness of the central portion 22, and the size of the umbrella-shaped portion 112 is larger than the diameter of the rod-shaped portion 111. When the central portion 22 is inserted into the mounting buckle 11, the umbrella-shaped portion 112 abuts against the front surface 222 of the central portion 22 away from the base 11 to limit the relative movement of the assembly portion 10 and the first accessory 20 in the first direction B1.

[0074] Combination Figure 6 The mounting buckle 11 can be used to assemble the second accessory 30 , and here the second accessory 30 is taken as a rubber band as an example.

[0075] In addition, combined Figure 7 The auxiliary interface 102 as mentioned above is also formed on the outer side surface of the assembly portion 10, and the auxiliary interface 102 can be used to assemble the third accessory 40. Here, the third accessory 40 is an archwire as an example.

[0076] It should be noted that after the first accessory 20 is assembled, the auxiliary interface 102 can be exposed on the outside of the first accessory 20, so that the assembly part 10 can assemble the first accessory 20 and the third accessory 40 at the same time, or, after the first accessory 20 is assembled, the auxiliary interface 102 is blocked by the first accessory 20, at this time, the first accessory 20 or the third accessory 40 can be selectively assembled, and the second accessory 30 can also be selectively assembled.

[0077] Combination Figure 8 and Fig. 9 , is a schematic diagram of a dental component 200a according to a second embodiment.

[0078] The main difference between the second embodiment and the first embodiment is that the notch 221a on the central portion 22a includes a plurality of interconnected limiting holes 2212a. When the mounting buckle 11a is engaged with different limiting holes 2212a, the second relative position between the assembly portion 10a and the first accessory 20a in the second direction B2 or the third relative position in the third direction B3 changes. In this way, multi-directional adjustment of the first accessory 20a can be achieved.

[0079] Combination Figures 10 to 19 , is a schematic diagram of a dental component 200b according to a third embodiment.

[0080] The dental component 200b includes a mounting portion 10b fixedly connected to a mounting surface 101b of an orthodontic appliance 100b and a first accessory 20b mounted on the mounting portion 10b. The first accessory 20b is taken as a jaw pad as an example.

[0081] The assembly portion 10b is a mounting buckle 11b fixedly connected to the mounting surface 101b. The first accessory 20b includes a plurality of through holes 203b. The mounting buckle 11b cooperates with different through holes 203b to adjust at least one of the first relative position, the second relative position, and the third relative position, that is, the jaw pad 20b can be adjusted to different positions.

[0082] For example, combined with Fig.16 When the plurality of through holes 203b are arranged along the third direction B3, the plurality of through holes 203b are interconnected along the third direction, and the position of the jaw pad 20b in the mesiodistal direction can be adjusted.

[0083] Combination Fig.17 When the plurality of through holes 203b are arranged along the second direction B2, the height of the jaw pad 20b can be adjusted.

[0084] Combination Fig.18 and Fig.19When multiple through holes 203b are arranged along the second direction B2 and the third direction B3 at the same time or multiple through holes 203b are arranged along the angle direction between the second direction B2 and the third direction B3, the position and height of the jaw pad 20b in the mesiodistal direction can be adjusted at the same time.

[0085] In addition, the mounting buckles 11b can be simultaneously provided on the buccal surface A1 and the lingual surface A3 of the orthodontic appliance 100b to fix the arched jaw pad 20b. Multiple mounting buckles 11b can be provided on one side of the orthodontic appliance 100b, and the multiple mounting buckles 11b are all matched with the through hole 203b to improve the stability of the assembly of the jaw pad 20b.

[0086] In summary, the present invention can improve the assembly freedom of the first accessory 20 by setting the assembly part 10. Specifically, the assembly part 10 is a universal assembly part. By changing the relative position between the assembly part 10 and the first accessory 20, the first accessory 20 can be in different working forms to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0087] In addition, the present invention can achieve complete fixation between the assembly portion 10 and the first accessory 20, so that the first accessory 20 can provide a stable correction effect.
