[0042] 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, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0043] In combination with Figures 1 to 5 , an orthodontic appliance assembly 200 is provided in an embodiment of the present invention.

[0044] The orthodontic appliance assembly 200 includes two orthodontic appliances 201 and 202 corresponding to the upper teeth and the lower teeth respectively, and at least one set of limiting components 100 connecting the two orthodontic appliances 201 and 202.

[0045] Both of the two orthodontic appliances 201 and 202 are invisible orthodontic appliances made of polymer materials. One of the two orthodontic appliances 201 and 202 has a first cavity that matches the upper teeth, and the other has a second cavity that matches the lower teeth.

[0046] Optionally, taking the two orthodontic appliances 201 and 202 as the first orthodontic appliance 201 corresponding to the upper teeth and the second orthodontic appliance 202 corresponding to the lower teeth as an example, the first orthodontic appliance 201 has a first cavity S1 that matches the upper teeth, and the second orthodontic appliance 202 has a second cavity S2 that matches the lower teeth.

[0047] The limiting component 100 is used to limit the relative movement between the first orthodontic appliance 201 and the second orthodontic appliance 202. When the patient wears the orthodontic appliance assembly 200, the first orthodontic appliance 201 is worn on the upper teeth, and the second orthodontic appliance 202 is worn on the lower teeth. The limiting component 100 can keep the first orthodontic appliance 201 and the second orthodontic appliance 202 in a preset relative position, so as to achieve tooth correction, such as achieving jaw position adjustment, etc.

[0048] Optionally, a first design amount may be designed at the first orthodontic appliance 201. When the first orthodontic appliance 201 is worn on the upper teeth, the first design amount can achieve the movement, rotation, etc. of the upper teeth, but not limited thereto. The first orthodontic appliance 201 may also have no design amount.

[0049] For the description of the second orthodontic appliance 202, reference may be made to the first orthodontic appliance 201, which will not be elaborated herein.

[0050] Combined Figures 1 to 5 , the limiting component 100 includes a first limiting group 10, a second limiting group, and a third limiting group. The first limiting group 10, the second limiting group, and the third limiting group are respectively configured to limit the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the first plane, the second plane, and the third plane. The first plane is perpendicular to the gingival occlusal surface direction z, the second plane is perpendicular to the mesiodistal direction x, and the third plane is perpendicular to the buccolingual direction y. The limiting component 100 includes a mechanical retention structure.

[0051] Optionally, since the dental arch generally extends in an arc shape, for different regions of the dental arch, the mesiodistal direction x and the buccolingual direction y are not fixed directions. Therefore, for different regions of the dental arch, the first plane, the second plane, and the third plane are not fixed planes.

[0052] For example, the orthodontic appliance assembly 200 includes at least two limiting regions arranged along the mesiodistal direction x, and at least two sets of limiting components 100 located in the at least two limiting regions. The limiting component 100 limits the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the first plane, the second plane, and the third plane of the corresponding limiting region. At this time, the at least two sets of limiting components 100 can cover the entire dental arch to limit the relative movement and relative rotation of all regions of the first orthodontic appliance 201 and the second orthodontic appliance 202.

[0053] The at least two limiting regions include, for example, a left half-jaw region and a right half-jaw region. The at least two sets of limiting components 100 include, for example, a first set of limiting components located in the left half-jaw region and a second set of limiting components located in the right half-jaw region. The first set of limiting components is arranged in the left half-jaw region, and the first set of limiting components limits the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the first plane, the second plane, and the third plane defined by the left half-jaw region. The second set of limiting components is arranged in the right half-jaw region, and the second set of limiting components limits the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the first plane, the second plane, and the third plane defined by the right half-jaw region.

[0054] Optionally, at least two sets of limiting components 100 may be mutually disconnected limiting components, or at least a part of the structures of at least two sets of limiting components 100 are interconnected. At least two sets of limiting components 100 may also be regarded as a set of limiting components 100 corresponding to the entire dental arch.

[0055] "The limiting component 100 includes a mechanical retention structure" means that at least a part of the structure in the limiting component 100 is a mechanical retention structure. The mechanical retention structure is defined as a structure that realizes mutual limitation through the mutual cooperation of physical structures, such as concave-convex cooperation, snap fit, embedding, socketing, riveting, etc. Different from the adhesive retention structure or the welding retention structure, the mechanical retention structure is a non-fluid retention form, which can avoid the problem of retention failure under harsh environments (such as high temperature or large external force) brought by the flowable properties of adhesive materials and welding materials, and thus can greatly improve the retention effect.

[0056] In this embodiment, the first appliance 201 and the second appliance 202 are connected by the limiting component 100. The limiting component 100 simultaneously realizes the relative movement and relative rotation limitation of the first appliance 201 and the second appliance 202 in the first plane, the second plane and the third plane, that is, the all-round relative movement and relative rotation of the first appliance 201 and the second appliance 202 are restricted, and the all-round stable retention between the first appliance 201 and the second appliance 202 can be realized, greatly improving the connection stability between the first appliance 201 and the second appliance 202, and further improving the corresponding tooth correction effect.

[0057] Optionally, the limiting component 100 includes a first limiting part 40, a second limiting part 50 and a third limiting part 60.

[0058] The first limiting part 40 is configured to limit the relative movement of the first appliance 201 and the second appliance 202 in the mesiodistal direction x, the second limiting part 50 is configured to limit the relative movement of the first appliance 201 and the second appliance 202 in the buccolingual direction y, and the third limiting part 60 is configured to limit the relative movement of the first appliance 201 and the second appliance 202 in the gingival occlusal surface direction z.

[0059] The first limiting part 40 and the second limiting part 50 cooperate to form a first limiting group 10, that is, when the first limiting part 40 and the second limiting part 50 cooperate, they limit the relative movement and relative rotation of the first appliance 201 and the second appliance 202 in the first plane formed by the mesiodistal direction x and the buccolingual direction y.

[0060] The second limiting part 50 and the third limiting part 60 cooperate to form a second limiting group, that is, when the second limiting part 50 and the third limiting part 60 cooperate, they limit the relative movement and relative rotation of the first appliance 201 and the second appliance 202 in the second plane formed by the buccolingual direction y and the gingival occlusal surface direction z.

[0061] The first limiting part 40 and the third limiting part 60 cooperate to form a third limiting group, that is, when the first limiting part 40 and the third limiting part 60 cooperate, the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the third plane formed by the mesiodistal direction x and the gingival occlusal surface direction z are restricted.

[0062] Next, various specific embodiments of some or all of the components of the limiting assembly 100 will be introduced.

[0063] Combined with Figures 1 to 14 , it is a schematic diagram of the first limiting group 10 of the limiting assembly 100 of the first specific embodiment.

[0064] The two orthodontic appliances 201, 202 include a first occlusal surface and a second occlusal surface that are oppositely arranged. Here, it is taken as an example that the first orthodontic appliance 201 has a first occlusal surface 2011 and the second orthodontic appliance 202 has a second occlusal surface 2021.

[0065] The first orthodontic appliance 201 and the second orthodontic appliance 202 can be made of the same or different materials. For example, they are both TPU materials or PETG materials, or the first orthodontic appliance 201 is made of PETG material and the second orthodontic appliance 202 is made of TPU material.

[0066] The first limiting group 10 includes a concave part and a convex part that cooperate with each other. One of the concave part and the convex part is located on the first occlusal surface 2011, and the other is located on the second occlusal surface 2021. When the concave part and the convex part cooperate with each other, the relative movement and relative rotation of the first orthodontic appliance 201 and the second orthodontic appliance 202 in the first plane formed by the mesiodistal direction x and the buccolingual direction y are restricted. The convex part is a linear structure or a bent structure, but it is not limited thereto.

[0067] This specific embodiment may include the following several specific forms:

[0068] Combined with Figures 1 to 5 , Figure 5 is Figure 2 The schematic diagram of the A-A cross-section in. In the first form, the first limiting group 10 includes a convex part 11 located on the first occlusal surface 2011 of the first orthodontic appliance 201 and a concave part 12 located on the second occlusal surface 2021 of the second orthodontic appliance 202. The convex part 11 is two linearly arranged structures spaced apart, and the concave part 12 is a depression formed by a Z-shaped protrusion.

[0069] The Z-shaped protrusion at the second occlusal surface 2021 can also be regarded as a bent convex part 11, and the depression formed by the linear protrusion at the corresponding first occlusal surface 2011 can be regarded as the concave part 12. Or rather, the cooperation between the convex part 11 and the concave part 12 at this time can be regarded as the cooperation between two groups of convex parts.

[0070] Combination Figures 6 to 8 In the second form, the first limiting group 10a includes a convex portion 11a located on the first occlusal surface 2011a of the first orthodontic appliance 201a and a concave portion 12a located on the second occlusal surface 2021a of the second orthodontic appliance 202a. The convex portion 11a is a linear structure with three intervals, and the concave portion 12a is three depressions formed on the convex block with intervals.

[0071] The convex block at the second occlusal surface 2021a can also be regarded as the convex portion 11a, and the depression formed by the linear protrusion at the corresponding first occlusal surface 2011a can be regarded as the concave portion 12a. Or rather, the cooperation between the convex portion 11a and the concave portion 12a at this time can be regarded as the cooperation between two groups of convex portions.

[0072] Combination Figures 9 to 11 In the third form, the first limiting group 10b includes a convex portion 11b located on the first occlusal surface 2011b of the first orthodontic appliance 201b and a concave portion 12b located on the second occlusal surface 2021b of the second orthodontic appliance 202b. The convex portion 11b is a linear structure with four intervals, and the concave portion 12b is four depressions formed at the four corners of the convex block.

[0073] The convex block at the second occlusal surface 2021b can also be regarded as the convex portion 11b, and the depression formed by the linear protrusion at the corresponding first occlusal surface 2011b can be regarded as the concave portion 12b. Or rather, the cooperation between the convex portion 11b and the concave portion 12b at this time can be regarded as the cooperation between two groups of convex portions.

[0074] Combination Figures 12 to 14 In the fourth form, the first limiting group 10c includes a convex portion 11c located on the first occlusal surface 2011c of the first orthodontic appliance 201c and a concave portion 12c located on the second occlusal surface 2021c of the second orthodontic appliance 202c. The convex portion 11c is a linear structure with two intervals, and the concave portion 12c is a depression formed by two linear structures with intervals.

[0075] The linear protrusion at the second occlusal surface 2021c can also be regarded as the convex portion 11c, and the depression formed by the linear protrusion at the corresponding first occlusal surface 2011c can be regarded as the concave portion 12c. Or rather, the cooperation between the convex portion 11c and the concave portion 12c at this time can be regarded as the cooperation between two groups of convex portions.

[0076] Combination 15 to Figure 17 is a schematic diagram of the first limiting group 10d of the limiting component 100d in the second specific embodiment.

[0077] The two appliances 201d and 202d include a first occlusal surface and a second occlusal surface which are oppositely arranged. Here, the first appliance 201d has a first occlusal surface 2011d and the second appliance 202d has a second occlusal surface 2021d as an example.

[0078] The appliance assembly 200d further includes an intermediate structure 203d clamped between the first occlusal surface 2011d and the second occlusal surface 2021d. The intermediate structure 203d is made of a flexible material.

[0079] The first appliance 201d, the second appliance 202d and the intermediate structure 203d can be made of the same or different materials. For example, they are all made of TPU material or PETG material. Or, the first appliance 201d is made of PETG material, the second appliance 202d is made of TPU material, and the intermediate structure 203d is made of a material softer than the first appliance 201d and the second appliance 202d.

[0080] The intermediate structure 203d includes a first surface 2031d facing the first occlusal surface 2011d and a second surface 2032d facing the second occlusal surface 2021d. The first limiting group 10d includes a concave part and a convex part which cooperate with each other. One of the concave part and the convex part is located on the first occlusal surface 2011d, and the other is located on the first surface 2031d. And one of the concave part and the convex part is located on the second occlusal surface 2021d, and the other is located on the second surface 2032d. When the concave part and the convex part cooperate with each other, the relative movement and relative rotation of the first appliance 201d and the second appliance 202d in the first plane formed in the mesiodistal direction x and the buccolingual direction y are restricted.

[0081] Specifically, the first limiting group 10d includes two sets of concave parts and convex parts which cooperate with each other. The first set of concave parts and convex parts includes two first convex parts 11d located on the first occlusal surface 2011d of the first appliance 201d and two first concave parts 12d located on the first surface 2031d of the intermediate structure 203d. The second set of concave parts and convex parts includes two second convex parts 11d' located on the second occlusal surface 2021d of the second appliance 202d and two second concave parts 12d' located on the second surface 2032d of the intermediate structure 203d.

[0082] The number of the first convex parts 11d, the first concave parts 12d, the second convex parts 11d' and the second concave parts 12d' is not limited to two, and can be determined according to the actual situation. And the two first convex parts 11d are roughly located in the anterior tooth area of the first occlusal surface 2011d, and the two second convex parts 11d' are roughly located in the two posterior tooth areas of the second occlusal surface 2021d, but not limited to this.

[0083] Combined with 18 to Figure 20 , it is a schematic diagram of the limiting component 100e of the third specific embodiment.

[0084] The main difference between this specific embodiment and the second specific embodiment is that: in the gingival occlusal surface direction z, the convex part is a conical structure, and the convex part and the concave part cooperate to form a third limiting part 60e.

[0085] Specifically, in the third specific embodiment, the first limiting group 10e includes two sets of cooperating concave parts and convex parts. The first set of concave parts and convex parts includes two first convex parts 11e located on the first occlusal surface 2011e of the first orthodontic appliance 201e and two first concave parts 12e located on the first surface 2031e of the intermediate structure 203e. The second set of concave parts and convex parts includes two second convex parts 11e' located on the second occlusal surface 2021e of the second orthodontic appliance 202e and two second concave parts 12e' located on the second surface 2032e of the intermediate structure 203e.

[0086] The first convex part 11e and the second convex part 11e' are conical structures, and the corresponding first concave part 12e and the second concave part 12e' are also conical structures. When the concave part and the convex part cooperate with each other, the relative movement and relative rotation of the first orthodontic appliance 201e and the second orthodontic appliance 202e in the first plane formed in the mesiodistal direction x and the buccolingual direction y are restricted. At the same time, the cooperation between the conical first convex part 11e and the first concave part 12e can restrict the relative movement of the first orthodontic appliance 201e and the intermediate structure 203e in the gingival occlusal surface direction z, that is, the first convex part 11e and the first concave part 12e cooperate to form a third limiting part 60e. The cooperation between the conical second convex part 11e' and the second concave part 12e' can restrict the relative movement of the second orthodontic appliance 202e and the intermediate structure 203e in the gingival occlusal surface direction z, that is, the second convex part 11e' and the second concave part 12e' cooperate to form a third limiting part 60e.

[0087] In the third specific embodiment, the cooperating concave parts and convex parts not only restrict the relative movement and relative rotation of the first orthodontic appliance 201e and the second orthodontic appliance 202e in the first plane formed in the mesiodistal direction x and the buccolingual direction y, but also restrict the relative movement of the first orthodontic appliance 201e and the second orthodontic appliance 202e in the gingival occlusal surface direction z.

[0088] In the first specific embodiment, in the gingival occlusal surface direction z, the convex part can also be a conical structure to form a third limiting part 60.

[0089] Optionally, in the above first to third specific embodiments, the concave part and the convex part are mechanical retention structures, and the third limiting part includes an adhesive retention structure, a welding retention structure, a riveting retention structure or a magnetic attraction retention structure located between the concave part and the convex part, that is, the relative movement of the first orthodontic appliance and the second orthodontic appliance in the gingival occlusal surface direction z can be further restricted by adhesive bonding, welding, riveting or magnetic attraction.

[0090] Combination Figures 21 to 23 is a schematic diagram of the limiting component 100f of the fourth specific embodiment.

[0091] The two orthodontic appliances 201f and 202f include a first occlusal surface and a second occlusal surface which are oppositely arranged. Here, it is taken as an example that the first orthodontic appliance 201f has a first occlusal surface 2011f and the second orthodontic appliance 202f has a second occlusal surface 2021f.

[0092] The third limiting part 60f includes a first retaining part 61f located on the first occlusal surface 2011f, a second retaining part 62f located on the second occlusal surface 2021f, and an adhesive retaining structure, a welding retaining structure, a riveting retaining structure or a magnetic attracting retaining structure located between the first retaining part 61f and the second retaining part 62f.

[0093] Specifically, the first retaining part 61f is a first platform protruding from the first occlusal surface 2011f, the second retaining part 62f is a second platform protruding from the second occlusal surface 2021f, and both the first retaining part 61f and the second retaining part 62f are frustum-shaped structures, but not limited thereto. When the first orthodontic appliance 201f and the second orthodontic appliance 202f cooperate with each other, the surface of the first retaining part 61f away from the first occlusal surface 2011f cooperates with the surface of the second retaining part 62f away from the second occlusal surface 2021f, and there can be an adhesive retaining structure, a welding retaining structure, a riveting retaining structure or a magnetic attracting retaining structure between the two planes. In this way, the relative movement of the first orthodontic appliance 201f and the second orthodontic appliance 202f in the gingival occlusal surface direction z can be restricted.

[0094] The third limiting part 60f includes two sets of mutually cooperating first retaining parts 61f and second retaining parts 62f respectively located in the left and right posterior tooth regions, but not limited thereto. The third limiting part 60f can also be arranged at other positions.

[0095] In addition, the limiting component 100f further includes a first limiting group 10f. The first limiting group 10f includes a concave part and a convex part which cooperate with each other. The first limiting group 10f simultaneously covers the anterior tooth region and the two posterior tooth regions, and the first limiting group 10f is located between the two sets of first retaining parts 61f and second retaining parts 62f. In this way, when the concave part and the convex part cooperate with each other, the relative movement and relative rotation of the first orthodontic appliance 201f and the second orthodontic appliance 202f in the first plane formed by the mesiodistal direction x and the buccolingual direction y are restricted.

[0096] Combination 24 and Figure 25 is a schematic diagram of the limiting component 100g of the fifth specific embodiment.

[0097] One of the two appliances 201g and 202g includes a first buccal surface and a first lingual surface that are oppositely arranged, and the other includes a second buccal surface and a second lingual surface that are oppositely arranged. Here, it is taken as an example that the first appliance 201g has a first buccal surface 2012g and a first lingual surface 2013g that are oppositely arranged, and the second appliance 202g has a second buccal surface 2022g and a second lingual surface 2023g that are oppositely arranged.

[0098] The third limiting part 60g includes at least one connecting part 63g. The connecting part 63g connects the first buccal surface 2012g and the second buccal surface 2022g, or the connecting part 63g connects the first lingual surface 2013g and the second lingual surface 2023g. The connecting part 63g can limit the relative movement of the first appliance 201g and the second appliance 202g in the gingival occlusal surface direction z.

[0099] In addition, the first appliance 201g further includes a first occlusal surface 2011g, the second appliance 202g further includes a second occlusal surface 2021g, and the limiting component 100g further includes a first limiting group 10g located between the first occlusal surface 2011g and the second occlusal surface 2021g to limit the relative movement and relative rotation of the first appliance 201g and the second appliance 202g in the first plane formed by the mesiodistal direction x and the buccolingual direction y.

[0100] The connecting part 63g includes at least two bases 6301g and a connecting member 6302g connecting the at least two bases 6301g. The at least two bases 6301g are located on the first buccal surface 2012g and the second buccal surface 2022g, or the at least two bases 6301g are located on the first lingual surface 2013g and the second lingual surface 2023g. The connecting member 6302g and the base 6301g are elastically connected or rigidly connected.

[0101] The number of the bases 6301g is even or odd. When the number of the bases 6301g is 2, the connection line of the two bases 6301g is parallel to the gingival occlusal surface direction z. When the number of the bases 6301g is an even number greater than 2, the multiple bases 6301g can be arranged in an array, and the connection line of adjacent bases 6301g is parallel to the gingival occlusal surface direction z or parallel to the mesiodistal direction x. When the number of the bases 6301g is odd, the connection line of adjacent bases 6301g can include a connection line parallel to the gingival occlusal surface direction z. Of course, the connection line direction of adjacent bases 6301g can be determined according to the actual situation and can also be inclined.

[0102] Combined Figure 24 and Figure 25, the connection member 6302g is elastically connected to the base 6301g. When the first orthodontic appliance 201g and the second orthodontic appliance 202g move relative to each other, the connection member 6302g is in a deformed state and generates a pre-tightening force that restricts the relative movement between the first orthodontic appliance 201g and the second orthodontic appliance 202g.

[0103] That is to say, when the first orthodontic appliance 201g and the second orthodontic appliance 202g move relative to each other, the pre-tightening force can restrict this relative movement. The design of the pre-tightening force can avoid the problem of the fixation failure between the first orthodontic appliance 201g and the second orthodontic appliance 202g caused by the deformation of the protrusions in the aforementioned first limiting group during use. In addition, the pre-tightening force makes the first orthodontic appliance 201g and the second orthodontic appliance 202g fit tightly together and still will not separate under a certain vertical perturbation, avoiding the reciprocating movement or loosening of the first orthodontic appliance 201g and the second orthodontic appliance 202g.

[0104] As Figures 18 to 20 shown, when the pre-tightening force is applied to the third specific embodiment, an intermediate structure 203e is provided between the first orthodontic appliance 201e and the second orthodontic appliance 202e. The existence of the pre-tightening force can tightly fasten the three together, and at the same time, the pre-tightening force can generate a large frictional force between the intermediate structure 203e and the first orthodontic appliance 201e and the second orthodontic appliance 202e, thereby restricting the relative movement and relative rotation of the first orthodontic appliance 201e and the second orthodontic appliance 202e in the first plane.

[0105] Specifically, the connection member 6302g is configured such that when the first orthodontic appliance 201g and the second orthodontic appliance 202g are in a closed state, the connection member 6302g is in a deformed state and generates a pre-tightening force.

[0106] That is to say, when the first orthodontic appliance 201g and the second orthodontic appliance 202g are in a closed state, the connection member 6302g is already in a deformed state, and at this time, the connection member 6302g can already restrict the relative movement between the first orthodontic appliance 201g and the second orthodontic appliance 202g.

[0107] When the first orthodontic appliance 201g and the second orthodontic appliance 202g move relative to each other and cause the first orthodontic appliance 201g and the second orthodontic appliance 202g to separate from each other, if the external force forcing the first orthodontic appliance 201g and the second orthodontic appliance 202g to separate from each other is greater than the pre-tightening force in the closed state, this external force will drive the connection member 6302g to further deform and generate a greater pre-tightening force, and the greater pre-tightening force can better prevent the first orthodontic appliance 201g and the second orthodontic appliance 202g from separating from each other.

[0108] Alternatively, the connecting member 6302g is configured such that when the first orthodontic appliance 201g and the second orthodontic appliance 202g are in a closed state, the connecting member 6302g is in an undeformed state. That is, only when the first orthodontic appliance 201g and the second orthodontic appliance 202g move relative to each other, the connecting member 6302g deforms to generate a pre-tightening force that restricts the relative movement between the first orthodontic appliance 201g and the second orthodontic appliance 202g.

[0109] Optionally, the direction of the pre-tightening force is the direction that drives the first orthodontic appliance 201g and the second orthodontic appliance 202g to approach each other in the gingival occlusal surface direction z.

[0110] The extending direction of the connecting member 6302g is parallel to the gingival occlusal surface direction z to generate a pre-tightening force that drives the first orthodontic appliance 201g and the second orthodontic appliance 202g to approach each other. Alternatively, the extending direction of the connecting member 6302g is inclined to the gingival occlusal surface direction z to generate a component force that drives the first orthodontic appliance 201g and the second orthodontic appliance 202g to approach each other as the pre-tightening force.

[0111] Optionally, when the connecting portion 63g is located in the first region, the connection strength between the connecting member 6302g and the base 6301g is the first connection strength. When the connecting portion 63g is located in the second region, the connection strength between the connecting member 6302g and the base 6301g is the second connection strength. The first region is located on the mesial side of the second region, and the second connection strength is less than the first connection strength.

[0112] For example, the first region is the anterior tooth region, and the second region is the posterior tooth region. The positional differences between the upper and lower teeth in the posterior tooth region are relatively large. Therefore, a connecting portion 63g with a smaller connection strength is required to adapt to the positional differences between the upper and lower teeth.

[0113] Optionally, the base 6301g is a hook-like structure, a buckle-like structure, an opening structure, an orthodontic appliance slot, a tubular structure, or a groove-like structure. The connecting member 6302g is an elastic ring structure, a non-elastic ring structure, a rigid arch wire, a plate-like structure, or a C-shaped structure.

[0114] The cooperation mode between the connecting member 6302g and the base 6301g is at least one of traction, snap fit, locking, gluing, welding, and riveting.

[0115] The connection between the connecting member 6302g and the base 6301g is a fixed connection or a detachable connection.

The two connecting parts 631w, 632w are the first connecting part 631w and the second connecting part 632w. The first connecting part 631w connects the first buccal surface 2012w and the second buccal surface 2022w, and the second connecting part 632w connects the first lingual surface 2013w and the second lingual surface 2023w. And the first connecting part 631w and the second connecting part 632w are arranged corresponding to each other in the buccolingual direction y.

[0138] The statement that "the first connecting portion 631w and the second connecting portion 632w are correspondingly arranged in the buccolingual direction y" means that the first connecting portion 631w and the second connecting portion 632w are basically on the same straight line in the buccolingual direction y, and the first connecting portion 631w and the second connecting portion 632w are correspondingly arranged in the posterior tooth area or the anterior tooth area.

In the mesiodistal direction, the first connecting portion 631x is closer to the dental midline C than the second connecting portion 632x, that is, the first connecting portion 631x and the second connecting portion 632x correspond to different tooth regions.

[0153] Here, both the first connecting portion 631x and the second connecting portion 632x are located in the posterior tooth region, that is, there is no connecting portion in the anterior tooth region.
