[0101] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are included within the scope of protection of the present application.

[0102] 1 to 8 are schematic diagrams of a dental apparatus 200 according to an embodiment of the present application.

[0103] The dental instrument 200 includes an interface accessory 10 and a first functional accessory 20 assembled on the interface accessory 10 , wherein the interface accessory 10 is configured to provide at least two working modes for the assembled first functional accessory 20 .

[0104] Here, "at least two working forms" means that under different assembly conditions, the first functional accessory 20 can form at least two working forms. That is to say, when the assembly forms of the interface accessory 10 and the first functional accessory 20 are different, the working states displayed by the first functional accessory 20 are different. For example, the position, force direction, force intensity, etc. of the first functional accessory 20 itself are different, thereby adapting to different correction needs.

[0105] This embodiment can improve the assembly freedom of the first functional accessory 20 by providing an interface accessory 10. Specifically, the interface accessory 10 is a universal interface accessory. By changing the assembly form, the interface accessory 10 provides at least two working forms for the first functional accessory 20. When facing different correction needs, the first functional accessory 20 can achieve different working forms by changing the assembly form with the interface accessory 10 to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0106] In this embodiment, the two working forms correspond to the same first functional accessory 20, that is, the correction needs can be met by changing the working form of the first functional accessory 20 without changing the type of functional accessory, which can greatly improve the versatility of the first functional accessory 20.

[0107] In this embodiment, the interface accessory 10 is mounted to a mounting surface 101 .

[0108] Here, the mounting surface may be a tooth or maxillary surface, or the dental appliance 200 includes an invisible brace 100 having a mounting surface 101 . The invisible brace 100 refers to a shell-shaped dental appliance having a cavity for accommodating teeth.

[0109] In this embodiment, the interface accessory 10 is installed on the mounting surface 101 of the invisible braces 100 as an example. The interface accessory 10 is fixedly connected to the mounting surface 101 , or the interface accessory 10 is detachably connected to the mounting surface 101 .

[0110] Specifically, in this embodiment, the mounting surface 101 is located on the buccal surface A1 of the invisible braces 100. The mounting surface 101 is a flat plane, and the interface accessory 10 is bonded to the mounting surface 101, but this is not limited to it. The mounting surface 101 can also be located on the lingual surface A3 of the invisible braces 100, etc.

[0111] In this embodiment, in conjunction with Figure 8, the dental instrument 200 also includes a second functional accessory 30, and the interface accessory 10 includes a first interface 102 and a second interface 103. The first interface 102 is used to assemble the first functional accessory 20, and the second interface 103 is used to assemble the second functional accessory 30.

[0112] That is to say, the interface accessory 10 can be selectively connected to at least two types of functional accessories, which further improves the versatility of the interface accessory 10, and different types of functional accessories can adapt to different application scenarios, which can improve the overall versatility of the dental instrument 200. In addition, different types of functional accessories can be used in combination to improve the correction efficiency.

[0113] The first interface 102 and the second interface 103 are respectively at least one of a limiting surface, a limiting notch, and a limiting portion, but are not limited thereto.

[0114] The first functional accessory 20 and the second functional accessory 30 are respectively at least one of a traction hook, an arch wire, a rubber band, and a jaw pad, but are not limited thereto.

[0115] Here, archwires refer to products with archwires, such as products formed by combining archwires with extraoral arches, lip stops, palatal bead trainers, etc.

[0116] In this embodiment, with continued reference to FIG. 1 to FIG. 8 , the interface accessory 10 is configured to change its relative position with the first functional accessory 20 to provide at least two working modes for the first functional accessory 20 .

[0117] That is, when the relative position between the interface accessory 10 and the first functional accessory 20 changes, the working form of the first functional accessory 20 also changes.

[0118] Here, the first functional accessories 20 in different working forms correspond to the same correction step or different correction steps. For example, in the same correction step, the position of the first functional accessory 20 relative to the interface accessory 10 can be adjusted at different time periods to adjust the correction effect, or, in different correction steps, the position of the first functional accessory 20 relative to the interface accessory 10 can be adjusted to match the correction requirements of different correction steps.

[0119] In a specific example, the interface accessory 10 is configured to change its relative position with the first functional accessory 20 according to different correction steps.

[0120] At this time, different correction steps can use the same interface accessory 10 and first functional accessory 20, which can greatly improve the versatility of the interface accessory 10 and the first functional accessory 20.

[0121] It is understandable that when this type of first functional accessory 20 cannot meet the correction needs, while changing the relative position of the interface accessory 10 and the first functional accessory 20, the type of the first functional accessory 20 can also be changed to adapt to more application scenarios.

[0122] In this embodiment, the relative position of the interface accessory 10 and the first functional 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.

[0123] That is to say, the relative position of the interface accessory 10 and the first functional accessory 20 can be adjusted in the up and down, left and right, front and back directions, or the relative position of the interface accessory 10 and the first functional accessory 20 refers to the relative angle between the two within the first plane C1, and the relative position of the interface accessory 10 and the first functional accessory 20 is adjusted by rotating the first functional accessory 20 within the first plane C1.

[0124] In a specific example, the first functional accessory 20 is a traction hook, which includes a base 201 and a hook 202 connected to each other. The base 201 is assembled on the interface accessory 10, and the hook 202 extends in a direction away from the base 201.

[0125] The interface accessory 10 includes a first limiting surface 11 (i.e., the first interface 102 includes the first limiting surface 11), and the first functional accessory 20 includes a second limiting surface 21 (i.e., the base 201 includes the second limiting surface 21). The first limiting surface 11 is configured to be in a different mating position with the second limiting surface 21 to provide at least two working forms for the first functional accessory 20.

[0126] In other words, when the first limiting surface 11 and the second limiting surface 21 are in different mating positions, the interface accessory 10 and the first functional accessory 20 form different relative angles (combined with Figures 3 and 4), or, when the base 201 and the interface accessory 10 are in different assembly positions, the hook 202 has different extension directions so that the first functional accessory 20 has at least two working forms.

[0127] It can be understood that when the first functional accessory 20 is rotated, the matching position of the second limiting surface 21 and the first limiting surface 11 will change, thereby causing the relative angle between the interface accessory 10 and the first functional accessory 20 to change, and the extension direction of the hook 202 in the first functional accessory 20 changes, so that the first functional accessory 20 produces a different working form.

[0128] Specifically, in conjunction with Figure 3, when the first limiting surface 11 and the second limiting surface 21 are in the first mating position, the first functional accessory 20 extends downward, that is, the hook 202 extends downward, and the relative angle between the interface accessory 10 and the first functional accessory 20 is defined as 0°.

[0129] Combined with Figure 4, after the first functional accessory 20 is rotated, the first limiting surface 11 and the second limiting surface 21 are in the second mating position, and the first functional accessory 20 extends toward the lower right corner, that is, the hook 202 extends toward the lower right corner. At this time, the relative angle between the interface accessory 10 and the first functional accessory 20 is defined as 30°, that is, the first functional accessory 20 is rotated 30° relative to the interface accessory 10.

[0130] It can be seen that when the matching position between the first limiting surface 11 and the second limiting surface 21 changes, the relative angle between the interface accessory 10 and the first functional accessory 20 also changes, thereby changing the extension direction of the hook 202. The hook 202 with different extension directions can adapt to different traction forces to form different working forms.

[0131] In this embodiment, the first limiting surface 11 is the outer surface of the interface accessory 10, the first functional accessory 20 includes a first through hole 203, and the second limiting surface 21 is the inner surface of the first through hole 203. The second limiting surface 21 is arranged around the outer side of the first limiting surface 11 and produces different matching positions with the first limiting surface 11. That is to say, the first functional accessory 20 and the interface accessory 10 are in a socketed matching manner, and different working forms can be provided for the first functional accessory 20 through different socketing angles.

[0132] Here, the first limiting surface 11 includes a plane or a curved surface. In this embodiment, the first limiting surface 11 is formed by splicing six planes as an example. The cross-section of the first limiting surface 11 is a hexagon, but it is not limited to this. The cross-section of the first limiting surface 11 can also be other polygons, or the first limiting surface 11 is formed by splicing multiple curved surfaces, or the first limiting surface 11 is formed by splicing curved surfaces and planes.

[0133] In addition to the adjustment of the relative angle between the interface accessory 10 and the first functional accessory 20 described above, in other embodiments, the adjustment of other relative positions of the interface accessory 10 and the first functional accessory 20 may also be involved. For example, one of the interface accessory 10 and the first functional accessory 20 includes a mating portion, and the other includes a plurality of locking portions, and the mating portion is mated to different locking portions to change at least one of the first relative position, the second relative position, and the third relative position.

[0134] Continuing with reference to FIG. 1 to FIG. 8 , in this embodiment, the dental apparatus 200 further includes a limiting accessory for limiting relative movement between the interface accessory 10 and the first functional accessory 20 in the first plane C1 and the first direction B1 .

[0135] That is to say, after the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the relative movement of the first functional accessory 20 and the interface accessory 10 in the first plane C1 and the first direction B1 is realized through the limiting accessory, that is, the relative stillness of the first functional accessory 20 and the interface accessory 10 is realized.

[0136] The limiting structure includes the aforementioned first limiting surface 11 located on the interface accessory 10 and the second limiting surface 21 located on the first functional accessory 20. The first limiting surface 11 and the second limiting surface 21 cooperate with each other to limit the relative movement of the interface accessory 10 and the first functional accessory 20 within the first plane C1.

[0137] As mentioned above, the first limiting surface 11 includes a plane or an arc surface. When the second limiting surface 21 is matched to the first limiting surface 11, at least part of the first limiting surface 11 and the second limiting surface 21 abut against each other to limit certain relative movements between the first functional accessory 20 and the interface accessory 10.

[0138] Specifically, after the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the first limiting surface 11 and the second limiting surface 21 can limit the relative rotation and relative movement of the interface accessory 10 and the first functional accessory 20 within the first plane C1.

[0139] The limiting accessory further includes a positioning portion and a positioning surface located on the first functional accessory 20 . The positioning portion and the positioning surface cooperate with each other to limit the relative movement between the interface accessory 10 and the first functional accessory 20 in the first direction B1 .

[0140] Several embodiments of the dental apparatus 200 are described below.

[0141] 1 to 8 are schematic diagrams of a dental apparatus 200 according to a first embodiment.

[0142] In the first embodiment, the dental apparatus 200 includes an interface accessory 10 fixedly connected to the invisible braces 100 and a first functional accessory 20 assembled on the interface accessory 10 , wherein the first functional accessory 20 is a traction hook as an example.

[0143] The outer side surface of the interface accessory 10 forms a first limiting surface 11 with a hexagonal cross-section. The first functional accessory 20 includes a first through hole 203. The inner surface of the first through hole 203 forms a second limiting surface 21 with a hexagonal cross-section. The first limiting surface 11 is completely matched with the second limiting surface 21.

[0144] When the first limiting surface 11 and the second limiting surface 21 are in different mating positions, the interface accessory 10 and the first functional accessory 20 form different relative angles so that the first functional accessory 20 has multiple working forms, that is, the hook portion 202 of the first functional accessory 20 at this time can form different extension directions to provide different forms of traction.

[0145] After the first functional accessory 20 is assembled to the interface accessory 10 according to the required working form, the first functional accessory 20 is sleeved on the outer side surface of the interface accessory 10 to limit the relative movement of the interface accessory 10 and the first functional accessory 20 in the first plane C1. Specifically, the first limiting surface 11 and the second limiting surface 21 are completely matched to limit the relative rotation and relative movement of the interface accessory 10 and the first functional accessory 20 in the first plane C1.

[0146] The positioning surface is a front surface 204 of the first functional accessory 20 that surrounds the interface accessory 10 and is away from the mounting surface 101 .

[0147] The positioning portion is a latch portion 40, and the interface accessory 10 has a second through hole 104. The latch portion 40 passes through the second through hole 104 and abuts the front surface 204, thereby limiting the first functional accessory 20 between the mounting surface 101 and the latch portion 40. In this way, the relative movement of the interface accessory 10 and the first functional accessory 20 in the first direction B1 can be limited.

[0148] At this time, the first functional accessory 20 is completely fixed to the interface accessory 10 , and the first functional accessory 20 can provide stable traction.

[0149] Here, the second through hole 104 includes a central through hole 1041 and two edge through holes 1042 that are interconnected. The latch portion 40 is a component independent of the interface accessory 10 and the first functional accessory 20. The latch portion 40 has two elastic walls 41 that are arranged opposite to each other and have a latch 411.

[0150] After the first functional accessory 20 is sleeved onto the outside of the interface accessory 10, the second through hole 104 is exposed, and the latch portion 40 is initially inserted into the middle through hole 1041. The two elastic walls 41 deform toward the middle so that the latch portion 40 can enter the middle through hole 1041. Then, the two elastic walls 41 are reset to drive the two latches 411 to enter the two edge through holes 1042 respectively, thereby achieving mutual fixation between the latch portion 40 and the interface accessory 10. At the same time, after the latch portion 40 passes through the second through hole 104, the two ends of the latch portion 40 protruding from the interface accessory 10 just abut the front surface 204 of the first functional accessory 20.

[0151] In addition, the two edge through holes 1042 are exposed outward to form the second interface 103 as described above. The second interface 103 is exposed outside the first functional accessory 20. The second interface 103 can be used to assemble the second functional accessory 30. Here, the second functional accessory 30 is an arch wire as an example.

[0152] Of course, in other implementations, the second interface 103 may also be formed in other areas or in other forms.

[0153] It should be noted that in other embodiments, a through hole can be formed on the first functional accessory 20 and the latch portion 40 can pass through the first functional accessory 20 and the interface accessory 10 at the same time. In this way, the thickness of the entire dental instrument 200 can be reduced and the first functional accessory 20 can be further fixed.

[0154] 9 to 12 are schematic diagrams of a dental apparatus 200 a according to a second embodiment. For ease of description, identical or similar components in different embodiments are numbered identically, and the same shall apply hereinafter.

[0155] In the second embodiment, the dental apparatus 200a includes an interface accessory 10a fixedly connected to the invisible braces 100a and a first functional accessory 20a assembled on the interface accessory 10a. For example, the first functional accessory 20a is a traction hook.

[0156] The outer side surface of the interface accessory 10a forms a first limiting surface 11a with a hexagonal cross section. The first functional accessory 20a includes a first through hole 203a. The inner surface of the first through hole 203a forms a second limiting surface 21a with a hexagonal cross section. The first limiting surface 11a is completely matched with the second limiting surface 21a.

[0157] When the first limiting surface 11a and the second limiting surface 21a are in different mating positions, the interface accessory 10a and the first functional accessory 20a form different relative angles so that the first functional accessory 20a has multiple working forms, that is, the hook portion of the first functional accessory 20a can form different extension directions to provide different forms of traction.

[0158] After the first functional accessory 20a is assembled to the interface accessory 10a according to the required working form, the first functional accessory 20a is sleeved on the outer side surface of the interface accessory 10a to limit the relative movement of the interface accessory 10a and the first functional accessory 20a in the first plane C1. Specifically, the first limiting surface 11a and the second limiting surface 21a are completely matched to limit the relative rotation and relative movement of the interface accessory 10a and the first functional accessory 20a in the first plane C1.

[0159] The positioning surface is a front surface 204 a of the first functional accessory 20 a surrounding the interface accessory 10 a and away from the mounting surface 101 a .

[0160] The positioning portion is a hook 50a located on the interface accessory 10a. The hook 50a abuts the front surface 204a, thereby limiting the first functional accessory 20a between the mounting surface 101a and the hook 50a. In this way, the relative movement of the interface accessory 10a and the first functional accessory 20a in the first direction B1 can be limited.

[0161] At this time, the first functional accessory 20a is completely fixed to the interface accessory 10a, and the first functional accessory 20a can provide stable traction.

[0162] Here, two oppositely arranged recessed portions 105a are formed on the interface accessory 10a, and two hooks 50a are respectively arranged in the two recessed portions 105a. The hooks 50a can be deformed in the recessed portions 105a, and the undeformed hooks 50a protrude from the outer side surface of the interface accessory 10a. The hooks 50a can be integrally formed with the interface accessory 10a.

[0163] When the first functional accessory 20a is being sleeved onto the outside of the interface accessory 10a, the two hooks 50a are squeezed so that the first functional accessory 20a passes smoothly through the hooks 50a and is assembled onto the interface accessory 10a. Then, the two hooks 50a are reset so that the hooks 50a just abut the front surface 204a of the first functional accessory 20a.

[0164] In addition, referring to FIG12 , the outer surface of the interface accessory 10a is further formed with the aforementioned second interface 103a, which can be used to assemble the second functional accessory 30a. Here, the second functional accessory 30a is an archwire as an example.

[0165] It should be noted that after the first functional accessory 20a is assembled, the second interface 103a can be exposed on the outside of the first functional accessory 20a. In this way, the interface accessory 10a can be equipped with the first functional accessory 20a and the second functional accessory 30a at the same time. Alternatively, after the first functional accessory 20a is assembled, the second interface 103a is blocked by the first functional accessory 20a. At this time, the first functional accessory 20a or the second functional accessory 30a can be selectively assembled.

[0166] 13 to 18 are schematic diagrams of a dental apparatus 200 b according to a third embodiment.

[0167] In the third embodiment, the dental apparatus 200b includes an interface accessory 10b fixedly connected to the invisible braces 100b and a first functional accessory 20b assembled on the interface accessory 10b. The first functional accessory 20b is, for example, a traction hook.

[0168] The outer side surface of the interface attachment 10b forms a first limiting surface 11b with a hexagonal cross section.

[0169] The first functional accessory 20b includes a first part 205b and a second part 206b connected to each other. The first part 205b is sleeved on the outer side of the interface accessory 10b. The inner surface of the first part 205b forms a second limiting surface 21b. The first limiting surface 11b partially matches the second limiting surface 21b.

[0170] Here, "partial matching of the first limiting surface 11b and the second limiting surface 21b" means that when the second limiting surface 21b is fitted to the first limiting surface 11b, the second limiting surface 21b only covers a partial area of ​​the first limiting surface 11b, and the first limiting surface 11b and the second limiting surface 21b partially match to limit the relative rotation and partial relative movement of the interface accessory 10b and the first functional accessory 20b within the first plane C1.

[0171] When the first limiting surface 11b and the second limiting surface 21b are in different mating positions, the interface accessory 10b and the first functional accessory 20b form different relative angles so that the first functional accessory 20b has multiple working forms, that is, the hook portion of the first functional accessory 20b at this time can form different extension directions to provide different forms of traction.

[0172] A notch 2061b is formed in the second portion 206b of the first functional accessory 20b.

[0173] The positioning portion is a traction buckle 60b located on a side of the interface accessory 10b away from the mounting surface 101b.

[0174] The positioning surface is the front surface 204b of the second portion 206b surrounding the notch 2061b and away from the mounting surface 101b.

[0175] After the first functional accessory 20b is assembled to the interface accessory 10b according to the required working form, the first part 205b is sleeved on the outer side surface of the interface accessory 10b and the notch 2061b cooperates with the traction buckle 60b to limit the relative movement of the interface accessory 10b and the first functional accessory 20b in the first plane C1. At the same time, the traction buckle 60b abuts the front surface 204b to limit the first functional accessory 20b between the accessory interface 10b and the traction buckle 60b. In this way, the relative movement of the interface accessory 10b and the first functional accessory 20b in the first direction B1 can be limited.

[0176] At this time, the first functional accessory 20b is completely fixed to the interface accessory 10b, and the first functional accessory 20b can provide stable traction.

[0177] 17 , the traction buckle 60b can be used to assemble the second functional accessory 30b. Here, the second functional accessory 30b is taken as a rubber band as an example.

[0178] In addition, referring to FIG18 , the outer surface of the interface accessory 10b is further formed with the aforementioned second interface 103b, which can be used to assemble the second functional accessory 30b. Here, the second functional accessory 30b is taken as an archwire as an example.

[0179] It should be noted that after the first functional accessory 20b is assembled, the second interface 103b can be exposed on the outside of the first functional accessory 20b. In this way, the interface accessory 10b can be equipped with the first functional accessory 20b and the second functional accessory 30b at the same time. Alternatively, after the first functional accessory 20b is assembled, the second interface 103b is blocked by the first functional accessory 20b. At this time, the first functional accessory 20b or the second functional accessory 30b can be selectively assembled.

[0180] 19 and 20 are schematic diagrams of a dental apparatus 200 c according to a fourth embodiment.

[0181] The main difference between the fourth embodiment and the third embodiment is that one of the interface accessory 10c and the first functional accessory 20c includes a mating portion, and the other includes multiple locking portions, and the mating portion is mated to different locking portions to change the second relative position or the third relative position.

[0182] Specifically, the mating portion is a traction buckle 60c located on the interface accessory 10c, and the multiple locking portions are a notch 2061c located on the second part 206c of the first functional accessory 20c. Here, the notch 2061c includes multiple connected limiting holes 2061c'. When the traction buckle 60c is matched to different limiting holes 2061c', the second relative position between the interface accessory 10c and the first functional accessory 20c 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 functional accessory 20c can be achieved.

[0183] 21 to 29 are schematic diagrams of a dental apparatus 200 d according to a fifth embodiment.

[0184] The dental device 200d includes an interface accessory 10d fixedly connected to the mounting surface 101d of the invisible braces 100d and a first functional accessory 20d assembled on the interface accessory 10d. The first functional accessory 20d is a jaw pad as an example.

[0185] The interface accessory 10d is a traction buckle 60d fixedly connected to the mounting surface 101d. The first functional accessory 20d includes a plurality of holes 207d that are interconnected. When the traction buckle 60d is fitted into different holes 207d, the interface accessory 10d and the first functional accessory 20d form different relative positions, so that the first functional accessory 20d has multiple working forms, that is, the jaw pad 20d can be adjusted to different positions.

[0186] For example, referring to FIG. 26 , when the plurality of holes 207 d are arranged along the third direction B3 , the position of the jaw pad 20 d in the mesiodistal direction can be adjusted.

[0187] 27 , when the plurality of holes 207d are arranged along the second direction B2, the height of the jaw pad 20d can be adjusted.

[0188] 28 and 29 , when multiple holes 207d are arranged simultaneously along the second direction B2 and the third direction B3 or multiple holes 207d are arranged along the angle between the second direction B2 and the third direction B3, the position and height of the jaw pad 20d in the mesiodistal direction can be adjusted simultaneously.

[0189] In addition, the traction buckle 60d can be set on the buccal surface A1 and the lingual surface A3 of the invisible braces 100d at the same time to fix the arched jaw pad 20d. Multiple traction buckles 60d can be set on one side of the invisible braces 100d, and the multiple traction buckles 60d are all matched with the holes 207d to improve the stability of the jaw pad 20d assembly.

[0190] To sum up, the present application can improve the assembly freedom of the first functional accessory 20 by setting the interface accessory 10. Specifically, the interface accessory 10 is a universal interface accessory. By changing the assembly form, the interface accessory 10 provides at least two working forms for the first functional accessory 20. When facing different correction needs, the first functional accessory 20 can achieve different working forms by changing the assembly form with the interface accessory 10 to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0191] In addition, the present application can achieve complete fixation between the interface accessory 10 and the first functional accessory 20 through different forms of limiting accessories, so that the first functional accessory 20 can provide a stable correction effect.

[0192] 30 to 36 are schematic diagrams of a dental assembly 200 according to an embodiment of the present application.

[0193] The dental assembly 200 includes an orthodontic appliance 100 , a mounting portion 10 connected to the orthodontic appliance 100 , and a first accessory 20 mounted on the mounting portion 10 .

[0194] 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 .

[0195] 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 .

[0196] Specifically, in this 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 to this. The mounting surface 101 may also be located on the lingual surface A3 of the orthodontic appliance 100, etc.

[0197] 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.

[0198] 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.

[0199] This embodiment can improve the assembly freedom of the first accessory 20 by providing 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 placed in different working forms to adapt to different correction needs, thereby greatly improving the correction freedom and correction effect.

[0200] 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.

[0201] 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.

[0202] In this embodiment, referring to FIG. 35 , the dental assembly 200 further includes a second accessory 30 , which is assembled at the mounting buckle 11 .

[0203] In addition, referring to FIG. 36 , the dental assembly 200 further includes a third accessory 40 , and the assembly portion 10 further includes an auxiliary interface 102 . The auxiliary structure 102 is used to assemble the third accessory 40 .

[0204] That is to say, the assembly portion 10 can be selectively connected to at least two types of accessories, which further improves the versatility of the assembly portion 10, and different types of accessories can adapt to different application scenarios, which can improve the overall versatility of the dental assembly 200. In addition, different types of accessories can be used in combination to improve the correction efficiency.

[0205] The first accessory 20 , the second accessory 30 , and the third accessory 40 are respectively at least one of a traction hook, an arch wire, a rubber band, and a jaw pad, but are not limited thereto.

[0206] Here, archwires refer to products with archwires, such as products formed by combining archwires with extraoral arches, lip stops, palatal bead trainers, etc.

[0207] 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.

[0208] 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 within 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.

[0209] 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.

[0210] Several embodiments of the dental assembly 200 are described below.

[0211] 30 to 36 are schematic diagrams of a dental assembly 200 according to a first embodiment.

[0212] In the first embodiment, the dental assembly 200 includes an assembly portion 10 fixedly connected to the orthodontic appliance 100 and a first accessory 20 assembled to the assembly portion 10 . For example, the first accessory 20 is a traction hook.

[0213] The traction hook includes a base portion 201 and a hook portion 202 . The base portion 201 is assembled on the assembly portion 10 .

[0214] 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.

[0215] 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.

[0216] 31 , 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°.

[0217] 32 , after the first accessory 20 is rotated, the inner wall 211 and the outer peripheral wall 121 are in the second mating position, and the first accessory 20 extends toward the lower right corner, that is, the hook 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.

[0218] It can be seen that when the mating 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.

[0219] 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. 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.

[0220] The inner wall 211 includes two parallel planes.

[0221] The inner wall 211 and the outer peripheral wall 121 are configured such that when the inner wall 211 and the outer peripheral wall 121 are in a certain mating position, the inner wall 211 and the outer peripheral wall 121 match to restrict the first accessory 20 from rotating relative to the base 12 within the first plane C1 .

[0222] That is, after the matching position between the inner wall 211 and the outer peripheral wall 121 is determined according to correction requirements, the inner wall 211 and the outer peripheral wall 121 are in planar contact, thereby restricting the first accessory 20 from rotating relative to the base 12 within the first plane C1.

[0223] 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.

[0224] The mounting buckle 11 is located on a side surface of the base 12 away from the orthodontic appliance 100 .

[0225] In this embodiment, the assembly portion 10 and the first accessory 20 are configured such that 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.

[0226] At this time, the first accessory 20 is completely fixed to the mounting portion 10 , and the first accessory 20 can provide stable traction.

[0227] 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.

[0228] 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. 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 limiting the relative movement of the assembly portion 10 and the first accessory 20 in the first plane C1 and the first direction B1.

[0229] It can be understood 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 can simplify the assembly difficulty.

[0230] In this embodiment, the notch 221 includes a connected channel 2211 and a limiting hole 2212 , and 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 .

[0231] Specifically, the diameter of the channel 2211 is smaller than the diameter of the rod-shaped portion 111, and the diameter of the limiting hole 2212 is roughly equal to the diameter of the rod-shaped portion 111. When the center 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.

[0232] In addition, the distance between the umbrella-shaped portion 112 and the base 12 is approximately 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, thereby limiting the relative movement of the assembly portion 10 and the first accessory 20 in the first direction B1.

[0233] 35 , the mounting buckle 11 can be used to assemble the second accessory 30 , where the second accessory 30 is a rubber band as an example.

[0234] In addition, referring to FIG36 , the outer surface of the assembly portion 10 is further formed with the auxiliary interface 102 as described above. The auxiliary interface 102 can be used to assemble the third accessory 40 . Here, the third accessory 40 is an archwire as an example.

[0235] 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. In this way, the assembly part 10 can assemble the first accessory 20 and the third accessory 40 at the same time. Alternatively, 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.

[0236] 37 and 38 are schematic diagrams of a dental assembly 200a according to a second embodiment.

[0237] 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 of 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, thereby enabling multi-directional adjustment of the first accessory 20a.

[0238] 39 to 48 are schematic diagrams of a dental assembly 200b according to a third embodiment.

[0239] The dental assembly 200b includes an assembly portion 10b fixedly connected to the mounting surface 101b of the orthodontic appliance 100b and a first accessory 20b assembled to the assembly portion 10b. The first accessory 20b is a jaw pad as an example.

[0240] The assembly portion 10b is a mounting buckle 11b fixedly connected to the mounting surface 101b. The first accessory 20b includes multiple through holes 203b. The mounting buckle 11b is matched 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.

[0241] For example, referring to FIG. 45 , when the plurality of through holes 203 b are arranged along the third direction B3 , the plurality of through holes 203 b are interconnected along the third direction, and the position of the jaw pad 20 b in the mesiodistal direction can be adjusted.

[0242] 46 , when the plurality of through holes 203 b are arranged along the second direction B2 , the height of the jaw pad 20 b can be adjusted.

[0243] 47 and 48 , when multiple through holes 203b are arranged simultaneously along the second direction B2 and the third direction B3 or multiple through holes 203b are arranged along the angle 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 simultaneously.

[0244] In addition, the mounting buckles 11b can be simultaneously set 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 set 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 jaw pad 20b assembly.

[0245] To sum up, the present application 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.

[0246] In addition, the present application 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.

[0247] Please refer to Figures 49 to 51, which schematically illustrate a shell-shaped dental instrument in an embodiment of the present application, which is installed with a first accessory 30 and a second accessory 40. The first accessory 30 is a traction hook, and the second accessory 40 is an archwire accessory.

[0248] The shell-shaped dental appliance includes a shell-shaped body 10 , which is formed with a cavity S for accommodating a tooth. The shell-shaped dental appliance also includes an accessory assembly. The accessory assembly may include an accessory and an accessory mounting seat 20 for mounting the accessory. The accessory mounting seat 20 may be provided on the shell-shaped body 10 .

[0249] In this embodiment, the accessory mounting seat 20 is formed separately from the shell-like body 10. The shell-like body 10 may be provided with an accessory mounting area, and the accessory mounting seat 20 may be mounted in the accessory mounting area. The accessory mounting area may have a bonding surface 11, and the accessory mounting seat 20 may have a bottom surface 21. Both the bottom surface 21 and the bonding surface 11 may be flat surfaces. The bottom surface 21 of the accessory mounting seat 20 and the bonding surface 11 may be bonded or welded together.

[0250] Of course, in other embodiments, the accessory mounting seat 20 may also be integrally formed with the shell-shaped body 10 .

[0251] In this embodiment, the accessory mounting seat 20 is staggered with a first accessory mounting portion and a second accessory mounting portion on the circumferential surface 23. The first accessory mounting portion is used to install the first accessory 30, and the second accessory mounting portion is used to install the second accessory 40. The first accessory 30 and the second accessory 40 can be installed on the accessory mounting seat 20 at the same time.

[0252] The accessory mount 20 may have a lingual side surface proximal to the tongue, a buccal side surface proximal to the buccal side, and a circumferential surface 23 connecting the lingual and buccal side surfaces. One of the lingual and buccal side surfaces may be a bottom surface 21 connected to the engagement surface 11 of the shell-shaped body 10, and the other may be a top surface 22. In this embodiment, the direction from the lingual side to the buccal side may be defined as the axial direction X, the direction surrounding the axial direction X as the circumferential direction Z, and the direction perpendicular to the axial direction X as the radial direction Y. When the bottom surface 21 is a flat surface, the axial direction X may be perpendicular to the bottom surface 21, and the radial direction Y may be parallel to the bottom surface 21.

[0253] The first accessory mounting portion and the second accessory mounting portion are both arranged on the circumferential surface 23. The staggered arrangement of the first accessory mounting portion and the second accessory mounting portion on the circumferential surface 23 can be understood as, in the axial direction X, the first accessory mounting portion and the second accessory mounting portion are at different axial X positions.

[0254] The first accessory 30 is detachably mounted on the first accessory mounting portion, and the second accessory 40 is also detachably mounted on the second accessory mounting portion, and the first accessory 30 and the second accessory 40 can be simultaneously mounted on the accessory base. In this way, when in use, the doctor can make a variety of choices according to needs, thereby improving the flexibility of the accessory assembly and reducing the number of times the orthodontic appliance is replaced.

[0255] 51 to 53 , which illustrate in detail the mounting structure of the first accessory 30. In this embodiment, the accessory mounting base 20 further includes a partition surface 27 disposed between the top surface 22 and the bottom surface 21. The circumferential surface 23 may include a first circumferential surface 231 connecting the top surface 22 and the partition surface 27, and a second circumferential surface 232 connecting the bottom surface 21 and the partition surface 27. The first accessory mounting portion includes a first mounting opening 24 disposed on the first circumferential surface 231, and the second accessory mounting portion includes a second mounting opening 25 disposed on the second circumferential surface 232.

[0256] In one embodiment of the present application, the first accessory mounting portion includes at least two first mounting openings 24 arranged in parallel along the circumferential direction Z. The first accessory 30 can be detachably mounted on any one of the first mounting openings 24. A limiting portion 26 is also provided in the accessory mounting seat 20 for limiting the movement of the first accessory 30 along the axial direction X and radial direction Y.

[0257] In this embodiment, at least two first mounting openings 24 are positioned substantially identically in the axial direction X. The openings of at least two first mounting openings 24 are oriented in different directions. During use, the physician can select which first accessory 30 to install in any of the first mounting openings 24. Different first mounting openings 24 provide mounting positions for the first accessory in different operating configurations. When the first accessory 30 is installed in different first mounting openings 24, the first accessory 30 operates in different configurations. Under different operating configurations, the magnitude and direction of the corrective force generated by the same accessory differ.

[0258] During use, the doctor can adjust the installation position of the first accessory according to the patient's treatment plan and selectively install the first accessory 30 into any of the first installation openings 24, thereby adjusting the working configuration of the first accessory 30. In different correction steps, the doctor can also directly adjust the working configuration of the first accessory 30 according to the patient's treatment plan without having to replace the shell-shaped body 10.

[0259] In the shell-shaped dental instrument provided in this embodiment, the accessory mounting seat 20 provides a first mounting port 24 with at least two working modes for the first accessory 30 , which can reduce the number of times the shell-shaped body is replaced.

[0260] In this way, when using the shell-shaped dental instrument, the doctor can select the most suitable angle to install the first attachment 30 according to the patient's condition to obtain the best correction force.

[0261] In this embodiment, the first accessory 30 is a traction hook. The first accessory 30 may include a rod portion, and the rod portion may include a working end and an assembly end. The working end may be provided with a hook head, and the assembly end may be inserted into the first mounting port 24 and fixed to the accessory mounting seat 20. The traction hook may be connected to an elastic member to apply traction. The magnitude and direction of the applied traction force will change depending on the direction of the traction hook. By providing a plurality of first mounting ports 24 with different opening directions in the circumferential direction Z, installation positions with working forms in different directions can be provided for the traction hook. The doctor can flexibly adjust the installation direction of the traction hook according to the patient's tooth arrangement and treatment plan without replacing the shell-like body 10, thereby adjusting the direction and magnitude of the force applied by the traction member.

[0262] Furthermore, a hollow portion communicating with the first mounting opening 24 may be defined between the top surface 22 and the partition surface 27. The hollow portion forms a stopper 26, and the first accessory 30 may include a mating portion 31 that engages with the stopper 26. When the first accessory 30 is mounted on the accessory mounting base 20, the mating portion 31 engages with the stopper 26. The mating portion 31 is disposed within the hollow portion, and the top surface 22 and the partition surface 27 can be used to restrict movement of the mating portion 31 along the axial direction X, thereby restricting movement of the first accessory 30 along the axial direction X.

[0263] The accessory mounting seat 20 is provided with a plurality of mounting walls 29 spaced apart along the circumferential direction Z. A first mounting opening 24 is formed between any two adjacent mounting walls 29. The inner ends 291 of the mounting walls 29 surround the hollow portion, and the limiting portion 26 may include the inner ends 291 of the mounting walls 29. When the first accessory 30 is mounted on the accessory mounting seat 20, the inner ends 291 of the mounting walls 29 abut against the mating portion 31 to limit movement of the mating portion 31 in the radial direction Y.

[0264] In this embodiment, the mating portion 31 may have a bottom surface, a top surface opposite the bottom surface, and a side surface connecting the bottom and top surfaces. The bottom and top surfaces of the mating portion 31 may be flat surfaces. When the first accessory 30 is mounted on the accessory mount 20, the bottom surface of the mating portion 31 is parallel to and in contact with the partition surface 27 of the accessory mount 20, and the top surface of the mating portion 31 is parallel to and in contact with the top surface of the accessory mount 20, thereby limiting movement of the mating portion 31 in the axial direction X. The inner end 291 of the mounting wall 29 abuts against the side surface of the mating portion 31, thereby limiting movement of the mating portion 31 in the radial direction Y. In other words, by providing the hollow portion to form the limiting portion 26, the first accessory 30 can be limited in both the axial direction X and the radial direction Y.

[0265] When the first accessory 30 is fixedly installed in the first installation opening, the matching portion 31 and the limiting portion 26 are interference-fitted, and the matching portion 31 and / or the limiting portion 26 can undergo elastic deformation.

[0266] In this embodiment, the hardness of one of the fitting portion 31 and the limiting portion 26 is higher than the hardness of the other, so that the installation and disassembly of the accessory can be facilitated, and the one with lower hardness between the fitting portion 31 and the limiting portion 26 can easily undergo elastic deformation to form an interference fit.

[0267] The interference fit between the mating portion 31 and the limiting portion 26 restricts the movement of the first accessory 30 relative to the accessory mounting base 20. The mating portion 31 can be provided at the assembly end of the rod portion of the first accessory 30. When the first accessory 30 is fixedly mounted in the first mounting opening 24, a portion of the rod portion can be inserted into the first mounting opening 24, providing a clearance fit between the rod portion and the first mounting opening 24. The rod portion extends in the same direction as the first mounting opening 24, and the first mounting opening 24 serves only as an orientation. Simultaneously, the interference fit between the mating portion 31 and the limiting portion 26 restricts the movement of the first accessory 30 relative to the accessory mounting base 20, thereby securing the first accessory 30 in the first mounting opening 24.

[0268] Furthermore, in one embodiment of the present application, the maximum width of the matching portion 31 is greater than the width of the first installation opening, and the matching portion 31 can be elastically deformed to pass through the first installation opening 24 and match with the limiting portion 26 .

[0269] In this embodiment, when installing the first accessory 30 into the first mounting opening 24, the first accessory 30 can be inserted into the first mounting opening 24 and a force applied toward the interior of the first mounting opening 24 is applied to push the first accessory 30 into the first mounting opening 24. Because the width of the mating portion 31 is greater than the width of the first mounting opening 24, the mating portion 31 undergoes elastic deformation until the mating portion 31 enters the stop portion 26 at the other end of the first mounting opening 24. There, the mating portion 31 and the stop portion 26 form an interference fit, and the mating portion 31 still undergoes elastic deformation, but the amount of elastic deformation is reduced. At this point, the first accessory 30 will not move unless a significant outward pulling force is applied to it. During use, the force applied to the first accessory 30, such as the pulling force applied to the towing hook, often forms a certain angle with the rod of the towing member, and does not apply a force along the extension direction of the rod to the towing hook. Furthermore, the pulling force is relatively small, and thus does not directly pull the first accessory 30 out of the first mounting opening 24.

[0270] After completing this correction step, the doctor applies an outward pulling force to the first attachment 30, causing the mating portion 31 to continue to elastically deform and disengage through the first installation opening 24. In the next correction step, the doctor can install the first attachment 30 in another first installation opening and adjust the installation position and correction force of the first attachment 30 based on the patient's tooth alignment and treatment plan.

[0271] In this embodiment, the side surface of the mating portion 31 includes concave arc surfaces 312 that are symmetrical at both ends and a convex arc surface 311 connecting the two concave arc surfaces 312. The distance between the two concave arc surfaces 312 increases from the side away from the convex arc surface 311 to the side close to the convex arc surface 311. When the first accessory 30 is installed on the accessory mounting base, the convex arc surface 311 contacts the inner end 291 of the mounting wall 29.

[0272] The mating portion 31 may be axially symmetrical, with the axis of symmetry passing through the center of the convex arc surface 311. The chord length of the convex arc of the convex arc surface 311 may be greater than the width of the first mounting opening 24, and the minimum distance between the two concave arc surfaces 312 may be less than the width of the first mounting opening 24.

[0273] The convex curved surface 311 can be the working end of the first accessory 30, while the concave curved surface 312 can be the assembly end of the first accessory 30, that is, the distal end of the first accessory 30. When installing the first accessory 30 into the accessory mounting base, the first accessory 30 is inserted into the first mounting opening 24 from the concave curved surface 312. The distance between the two concave curved surfaces 312 of the mating portion 31 gradually increases. The concave curved surface 312 can serve as a guide during insertion, making it easier to insert the mating portion 31 into the first mounting opening 24. When removing the first accessory 30, the convex curved surface 311 serves as a guide, making it easier to remove the first accessory 30 from the mounting opening.

[0274] In this embodiment, the cross-section of the end of the first mounting opening 24 away from the stop portion 26 is trapezoidal, and the width of the trapezoidal shape on the side closer to the stop portion 26 is smaller than the width on the side away from the stop portion 26. It will be appreciated that the opening of the first mounting opening 24 is a trumpet-shaped shape that expands outward, which makes it easier to insert the first accessory 30 into the first mounting opening 24.

[0275] Furthermore, in one embodiment of the present application, the number of first mounting openings 24 is even, and the first mounting openings 24 are collinear in pairs. The inner ends 291 of the mounting walls 29 of the two collinear first mounting openings 24 respectively abut against the convex arc surface 311 and the two concave arc surfaces 312. Both sides of the mating portion 31 can be simultaneously inserted into a pair of opposing first mounting openings 24.

[0276] In this embodiment, when there are two first mounting openings 24, the first accessory 30 can have two operating modes. In both operating modes, the relative angle of the first accessory 30 is 180°. The first accessory 30 can be inserted through one first mounting opening 24. When the first accessory 30 is inserted into the first mounting opening 24, the mating portion 31 and the stopper 26 engage, and the end of the first accessory 30 is inserted into the other first mounting opening 24 that is colinear with the first mounting opening 24. Of course, the accessory can also be inserted through the other first mounting opening 24. When the mating portion 31 and the stopper 26 engage, the end of the accessory is inserted into the first mounting opening 24.

[0277] In this way, the stability of the accessory installation can be improved. At the same time, the installation walls 29 of the two opposite first installation openings 24 are used for limiting, and the overall structure is simpler.

[0278] In this embodiment, the accessory mounting seat 20 may be provided with six first mounting openings 24, which may be arranged along the circumferential direction Z. Six mounting walls 29 may be spaced apart within the accessory mounting seat 20 along the circumferential direction Z, with a first mounting opening 24 formed between any two adjacent mounting walls 29. The limiting portion 26 includes inner ends 291 of the mounting walls 29. When the first accessory 30 is mounted on the mounting seat, the inner ends 291 of the mounting portion abut against the mating portion 31 to limit radial movement of the first accessory 30 in the radial direction Y. The distance between the ends of any two symmetrical mounting walls 29 is less than the chord length of the convex arc.

[0279] When the first accessory 30 is mounted on the accessory mounting base 20, the inner end 291 of the mounting wall 29 of the first mounting opening 24 for mounting the first accessory 30 abuts the convex curved surface 311. The inner end 291 of the mounting wall 29 of the opposite first mounting opening 24 abuts the concave curved surface 312. The other mounting walls 29 abut the connection between the concave curved surface 312 and the convex curved surface 311. Thus, the inner wall ends of all six mounting portions can limit the mating portion 31.

[0280] The distance between the ends of the two symmetrical mounting walls 29 is less than the chord length of the convex arc. Thus, when the mating portion 31 is mated with the limiting portion 26 , the two symmetrical mounting walls 29 press against the mating portion 31 to cause the mating portion 31 to elastically deform, and the mating portion 31 and the limiting portion 26 are interference fit.

[0281] In this embodiment, the cross-section of the mounting wall 29 can be an axisymmetric hexagon. The outer contour of the accessory mounting base 20 can be a hexagonal prism, with the six sides of the hexagonal prism forming a circumferential surface 23. Each of the six sides is defined by a first mounting opening 24. The axis of symmetry of the cross-section of the mounting wall 29 can pass through two symmetrical edges of the hexagonal prism.

[0282] In this embodiment, the bottom surface 21 of the accessory mounting base 20 can be adhered or welded to the outer surface of the shell body 10, and the center of the top surface 22 can be provided with an observation hole 28. The observation hole 28 can be directly opposite the area of ​​the stopper 26, and the observation hole 28 can be used to observe whether the accessory is properly installed.

[0283] Furthermore, referring to Figure 54 , which illustrates the mounting structure for an archwire accessory, in one embodiment of the present application, the second mounting openings 25 include two pairs of second mounting openings 25 extending through the second circumferential surface 232 . The two pairs of second mounting openings 25 are cross-shaped, with the bottom surface 21 and the partition surface 27 used to restrict movement of the second accessory 40 along the axial direction X.
