[0035] The present utility model 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 utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included within the protection scope of the present utility model.

[0036] In conjunction with Figures 1 to 3 , the embodiment of the present utility model provides a dental component 100.

[0037] The dental component 100 includes a first dental appliance 101 and a second dental appliance 102 corresponding to the upper teeth and the lower teeth respectively.

[0038] Here, both the first dental appliance 101 and the second dental appliance 102 are invisible dental appliances made of polymer materials. The first dental appliance 101 has a first cavity S1 that fits the upper teeth, and the second dental appliance 102 has a second cavity S2 that fits the lower teeth.

[0039] The first dental appliance 101 has a first buccal surface 1011 and a first lingual surface 1012 that are oppositely arranged, and a first occlusal surface 1013 sandwiched between the first buccal surface 1011 and the first lingual surface 1012. The first dental appliance 101 can be designed with a certain amount of orthodontic movement. Thus, when the first dental appliance 101 is worn on the upper teeth, the orthodontic movement can achieve the movement, rotation, etc. of the upper teeth, but not limited thereto. The first dental appliance 101 may also not be designed with an orthodontic movement.

[0040] Similarly, the second dental appliance 102 has a relatively arranged second buccal surface 1021 and a second lingual surface 1022, and a second occlusal surface 1023 sandwiched between the second buccal surface 1021 and the second lingual surface 1022. The second dental appliance 102 can be designed with a certain amount of orthodontic correction. Thus, when the second dental appliance 102 is worn on the mandibular teeth, the amount of orthodontic correction can achieve the movement, rotation, etc. of the mandibular teeth, but not limited thereto. The second dental appliance 102 can also be designed without an amount of orthodontic correction.

[0041] The dental assembly 100 further includes a plurality of retention structures 10. The retention structures 10 connect the first buccal surface 1011 and the second buccal surface 1021, or the retention structures 10 connect the first lingual surface 1012 and the second lingual surface 1022. That is, the retention structures 10 realize the mutual combination of the first dental appliance 101 and the second dental appliance 102.

[0042] The dental assembly 100 includes a first hemimaxilla P1 and a second hemimaxilla P2 located on both sides of the dental midline P. The plurality of retention structures 10 includes a first retention structure 11 and a second retention structure 12 located in the first hemimaxilla P1. In the mesiodistal direction x, the first retention structure 11 is closer to the dental midline P than the second retention structure 12.

[0043] That is to say, in the mesiodistal direction x, the first retention structure 11 and the second retention structure 12 are arranged at intervals from each other, and the first retention structure 11 and the second retention structure 12 are not on the same straight line extending in the buccolingual direction y. The first retention structure 11 is located on the mesial side of the second retention structure 12.

[0044] Specifically, the first retention structure 11 and the second retention structure 12 correspond to different tooth regions. For example, when both the first retention structure 11 and the second retention structure 12 correspond to teeth, the first retention structure 11 and the second retention structure 12 correspond to different teeth. When both the first retention structure 11 and the second retention structure 12 correspond to tooth gaps, the first retention structure 11 and the second retention structure 12 correspond to different tooth gaps. Generally speaking, the first retention structure 11 and the second retention structure 12 are not on the same straight line extending in the buccolingual direction y.

[0045] The first retention structure 11 of the present embodiment realizes the mutual connection of the first dental appliance 101 and the second dental appliance 102 in one region, and the second retention structure 12 realizes the mutual connection of the first dental appliance 101 and the second dental appliance 102 in another region. The mutual cooperation of the first retention structure 11 and the second retention structure 12 can generate a moment that restricts the relative rotation of the first dental appliance 101 and the second dental appliance 102. The moment restricts the rotation of the first dental appliance 101 and the second dental appliance 102 relative to at least one of a first rotation axis, a second rotation axis, or a third rotation axis. The first rotation axis extends in the mesiodistal direction x, the second rotation axis extends in the buccolingual direction y, and the third rotation axis extends in the gingival occlusal surface direction z.

[0046] The retention structure 10 connects the first buccal surface 1011 and the second buccal surface 1021, or the retention structure 10 connects the first lingual surface 1012 and the second lingual surface 1022, which can effectively limit the relative movement of the first dental appliance 101 and the second dental appliance 102 in the gingival occlusal surface direction z.

[0047] In this embodiment, the cooperation of the first retention structure 11 and the second retention structure 12 is used to limit the relative rotation and relative movement of the first dental appliance 101 and the second dental appliance 102, thereby effectively controlling the relative position between the first dental appliance 101 and the second dental appliance 102. When the relative position between the first dental appliance 101 and the second dental appliance 102 is relatively stable, the orthodontic effect can be effectively improved, such as in the application scenario of jaw position adjustment.

[0048] Compared with the form in which the entire dental component 100 has two retention structures, in this embodiment, the first retention structure 11 and the second retention structure 12 are provided in the first hemimaxilla P1. The mutual cooperation of the first retention structure 11 and the second retention structure 12 in a small range can more effectively generate a moment to limit the relative rotation of the first dental appliance 101 and the second dental appliance 102. By designing the reasonable number and setting position of the retention structure 10, etc., the effective control of the relative position between the first dental appliance 101 and the second dental appliance 102 can be achieved.

[0049] In addition, the first retention structure 11 and the second retention structure 12 at the first hemimaxilla P1 of the dental component 100 mainly restrict the relative rotation and relative movement of the first dental appliance 101 and the second dental appliance 102 in the first hemimaxilla P1 region. In order to improve the stability of the relative position between the entire first dental appliance 101 and the second dental appliance 102, a retention structure 10 can also be provided at the second hemimaxilla P2.

[0050] Optionally, in the first hemimaxilla P1, one of the first retention structure 11 and the second retention structure 12 connects the first buccal surface 1011 and the second buccal surface 1021 or connects the first lingual surface 1012 and the second lingual surface 1022, and the other connects the first buccal surface 1011 and the second buccal surface 1021 or connects the first lingual surface 1012 and the second lingual surface 1022. The first retention structure 11 and the second retention structure 12 can be located on the same side or different sides of the first hemimaxilla P1.

[0051] When the first retention structure 11 and the second retention structure 12 are located on the same side of the first hemimaxilla P1, the moment generated by the mutual cooperation of the first retention structure 11 and the second retention structure 12 mainly restricts the rotation of the first dental appliance 101 and the second dental appliance 102 relative to the second rotation axis, and the second rotation axis extends along the buccolingual direction y.

[0052] When the first retention structure 11 and the second retention structure 12 are located on the opposite sides of the first hemi - arch P1, the torque generated by the cooperation between the first retention structure 11 and the second retention structure 12 mainly restricts the rotation of the first dental cap 101 and the second dental cap 102 relative to the first rotation axis and the second rotation axis. The first rotation axis extends along the mesiodistal direction x, and the second rotation axis extends along the buccolingual direction y.

[0053] By controlling the number, setting position, extension direction, etc. of the retention structure 10, the torque can be effectively controlled.

[0054] Optionally, the first retention structure 11 is located in the anterior tooth area, and the second retention structure 12 is located in the posterior tooth area. Or, both the first retention structure 11 and the second retention structure 12 are located in the anterior tooth area. Or, both the first retention structure 11 and the second retention structure 12 are located in the posterior tooth area.

[0055] Next, several specific embodiments of the multiple retention structures 10 of the dental component 100 will be introduced.

[0056] Combined with Figures 1 to 13 , in the first specific embodiment, the first retention structure 11 connects the first buccal surface 1011 and the second buccal surface 1021, and the second retention structure 12 connects the first buccal surface 1011 and the second buccal surface 1021. That is, the first retention structure 11 and the second retention structure 12 are located on the same side of the first hemi - arch P1, and the first retention structure 11 is closer to the dental mid - line P than the second retention structure 12.

[0057] Multiple forms of the first specific embodiment include:

[0058] Such as Figures 1 to 4 shown, in the first form, the first retention structure 11 of the first hemi - arch P1 is located in the anterior tooth area, and the second retention structure 12 is located in the posterior tooth area. The first retention structure 11 located in the anterior tooth area connects the first buccal surface 1011 and the second buccal surface 1021, and the second retention structure 12 located in the posterior tooth area connects the first buccal surface 1011 and the second buccal surface 1021. That is, the first retention structure 11 and the second retention structure 12 are arranged at intervals in the mesiodistal direction x, and the torque generated by the cooperation between the first retention structure 11 and the second retention structure 12 mainly restricts the rotation of the first dental cap 101 and the second dental cap 102 relative to the second rotation axis. The second rotation axis extends along the buccolingual direction y.

[0059] The multiple retention structures 10 further include a fourth retention structure 14 and a fifth retention structure 15 located in the second hemi - arch P2. The fourth retention structure 14 is closer to the dental mid - line P than the fifth retention structure 15.

[0060] The fourth retention structure 14 is located in the anterior tooth area and connects the first buccal surface 1011 and the second buccal surface 1021. The fifth retention structure 15 is located in the posterior tooth area and connects the first buccal surface 1011 and the second buccal surface 1021. However, this is not limited thereto, and the fourth retention structure 14 and the fifth retention structure 15 may also be provided in other areas.

[0061] In the anterior tooth area and the posterior tooth area of the first half jaw P1 and the second half jaw P2 of the first form, there are retention structures 10, and the retention structures 10 are evenly distributed, which can improve the connection stability of the entire first dental appliance 101 and the second dental appliance 102.

[0062] As Figure 5 shown, there are multiple retention structures 10a of the second form.

[0063] The main difference between the second form and the first form is that the first retention structure 11a and the fourth retention structure 14a are a common structure located on the dental midline P, that is, the first retention structure 11a and the fourth retention structure 14a are the same structure.

[0064] Specifically, the multiple retention structures 10a include the first retention structure 11a and the second retention structure 12a located in the first half jaw P1, and the fourth retention structure 14a and the fifth retention structure 15a located in the second half jaw P2. The first retention structure 11a is closer to the dental midline P than the second retention structure 12a, and the fourth retention structure 14a is closer to the dental midline P than the fifth retention structure 15a.

[0065] The first retention structure 11a and the fourth retention structure 14a are both located on the dental midline P and are one structure. That is, the number of the multiple retention structures 10a at this time is three, and the number of the retention structures 10a can be reduced while ensuring the limiting effect.

[0066] As Figures 6 to 9 shown, in the third form, the first retention structure 11b of the first half jaw P1 is located in the anterior tooth area, and the second retention structure 12b is located in the posterior tooth area. The first retention structure 11b located in the anterior tooth area connects the first buccal surface 1011b and the second buccal surface 1021b, and the second retention structure 12b located in the posterior tooth area connects the first buccal surface 1011b and the second buccal surface 1021b. That is, the first retention structure 11b and the second retention structure 12b are arranged at intervals in the mesiodistal direction x, and the moment generated by the mutual cooperation of the first retention structure 11b and the second retention structure 12b mainly limits the rotation of the first dental appliance 101b and the second dental appliance 102b relative to the second rotation axis, and the second rotation axis extends along the buccolingual direction y.

[0067] The multiple retention structures 10b further include a third retention structure 13b located on the first hemimandible P1. The third retention structure 13b connects the first lingual surface 1012b and the second lingual surface 1022b. That is, the third retention structure 13b is on the opposite side of the first retention structure 11b (or the second retention structure 12b) on the first hemimandible P1. The torque generated by the cooperation between the third retention structure 13b and the first retention structure 11b (or the second retention structure 12b) mainly restricts the rotation of the first dental appliance 101b and the second dental appliance 102b relative to the first rotation axis and the second rotation axis. The first rotation axis extends along the mesiodistal direction x, and the second rotation axis extends along the buccolingual direction y.

[0068] Combined with Figure 8 , in the mesiodistal direction x, the third retention structure 13b is located between the first retention structure 11b and the second retention structure 12b. Thus, the layout stability of the first retention structure 11b, the second retention structure 12b, and the third retention structure 13b can be improved.

[0069] Or, combined with Figure 9 , the third retention structure 13b and the second retention structure 12b are correspondingly arranged in the buccolingual direction y, that is, the third retention structure 13b and the second retention structure 12b are generally located on the same straight line in the buccolingual direction y.

[0070] The multiple retention structures 10b further include a fourth retention structure 14b, a fifth retention structure 15b, and a sixth retention structure 16b located on the second hemimandible P2. The fourth retention structure 14b, the fifth retention structure 15b, and the sixth retention structure 16b on the second hemimandible P2 can refer to the first retention structure 11b, the second retention structure 12b, and the third retention structure 13b on the first hemimandible P1, but are not limited thereto.

[0071] As Figure 10 and Figure 11 shown, in the fourth form, both the first retention structure 11c and the second retention structure 12c on the first hemimandible P1 are located in the anterior tooth area. The first retention structure 11c connects the first buccal surface 1011c and the second buccal surface 1021c, and the second retention structure 12c connects the first buccal surface 1011c and the second buccal surface 1021c. That is, the first retention structure 11c and the second retention structure 12c are arranged at intervals in the mesiodistal direction x, and the torque generated by the cooperation between the first retention structure 11c and the second retention structure 12c mainly restricts the rotation of the first dental appliance 101c and the second dental appliance 102c relative to the second rotation axis. The second rotation axis extends along the buccolingual direction y.

[0072] The multiple retention structures 10c further include a fourth retention structure 14c and a fifth retention structure 15c located on the second hemimandible P2. The fourth retention structure 14c is closer to the dental midline P than the fifth retention structure 15c.

[0073] The fourth retention structure 14c and the fifth retention structure 15c are both located in the anterior tooth area and are both connected to the first buccal surface 1011c and the second buccal surface 1021c. However, this is not limited thereto, and the fourth retention structure 14c and the fifth retention structure 15c may also be provided in other areas.

[0074] The first retention structure 11c and the second retention structure 12c of the fourth form are both located in the anterior tooth area, that is, there is no retention structure in the posterior tooth area. Thus, the influence of the retention structure on the orthodontics of the posterior tooth area can be reduced.

[0075] Such as Figure 12 and Figure 13 As shown, in the fifth form, the first retention structure 11d and the second retention structure 12d of the first half jaw P1 are both located in the posterior tooth area. The first retention structure 11d is connected to the first buccal surface 1011d and the second buccal surface 1021d, and the second retention structure 12d is connected to the first buccal surface 1011d and the second buccal surface 1021d. That is, the first retention structure 11d and the second retention structure 12d are arranged at intervals in the mesiodistal direction x, and the moment generated by the mutual cooperation of the first retention structure 11d and the second retention structure 12d mainly restricts the rotation of the first dental appliance 101d and the second dental appliance 102d relative to the second rotation axis, and the second rotation axis extends along the buccolingual direction y.

[0076] The plurality of retention structures 10d further include a fourth retention structure 14d and a fifth retention structure 15d located in the second half jaw P2, and the fourth retention structure 14d is closer to the dental midline P than the fifth retention structure 15d.

[0077] The fourth retention structure 14d and the fifth retention structure 15d are both located in the posterior tooth area and are both connected to the first buccal surface 1011d and the second buccal surface 1021d. However, this is not limited thereto, and the fourth retention structure 14d and the fifth retention structure 15d may also be provided in other areas.

[0078] The first retention structure 11d and the second retention structure 12d of the fifth form are both located in the posterior tooth area, that is, there is no retention structure in the anterior tooth area. Thus, the influence of the retention structure on the orthodontics of the anterior tooth area can be reduced.

[0079] Combined with Figures 14 to 23 , in the second specific embodiment, the first retention structure 11e is connected to the first lingual surface 1012e and the second lingual surface 1022e, and the second retention structure 12e is connected to the first buccal surface 1011e and the second buccal surface 1021e. That is, the first retention structure 11e and the second retention structure 12e are located on opposite sides of the first half jaw P1, and the first retention structure 11e is closer to the dental midline P than the second retention structure 12e.

[0080] The various forms of the second specific embodiment include:

[0081] Such as Figures 14 to 16As shown, in the first form, the first retention structure 11e of the first hemimandible P1 is located in the anterior tooth region, and the second retention structure 12e is located in the posterior tooth region. The first retention structure 11e located in the anterior tooth region connects the first lingual surface 1012e and the second lingual surface 1022e, and the second retention structure 12e located in the posterior tooth region connects the first buccal surface 1011e and the second buccal surface 1021e. That is, the first retention structure 11e and the second retention structure 12e are spaced apart in the mesiodistal direction x, and the moment generated by the cooperation of the first retention structure 11e and the second retention structure 12e mainly restricts the rotation of the first dental cap 101e and the second dental cap 102e relative to the first rotation axis and the second rotation axis. The first rotation axis extends along the mesiodistal direction x, and the second rotation axis extends along the buccolingual direction y.

[0082] The multiple retention structures 10e further include a fourth retention structure 14e and a fifth retention structure 15e located in the second hemimandible P2. The fourth retention structure 14e is closer to the dental midline P than the fifth retention structure 15e.

[0083] The fourth retention structure 14e is located in the anterior tooth region and connects the first lingual surface 1012e and the second lingual surface 1022e, and the fifth retention structure 15e is located in the posterior tooth region and connects the first buccal surface 1011e and the second buccal surface 1021e. However, this is not limited thereto, and the fourth retention structure 14e and the fifth retention structure 15e can also be arranged in other regions.

[0084] In the anterior tooth region and the posterior tooth region of the first hemimandible P1 and the second hemimandible P2 in the first form, there are retention structures 10e, and the retention structures 10e are evenly distributed, which can improve the connection stability of the entire first dental cap 101e and the second dental cap 102e.

[0085] As Figure 17 shown, for the multiple retention structures 10f in the second form.

[0086] The main difference between the second form and the first form is that the first retention structure 11f and the fourth retention structure 14f are a common structure located on the dental midline L, that is, the first retention structure 11f and the fourth retention structure 14f are the same structure.

[0087] Specifically, the multiple retention structures 10f include a first retention structure 11f, a second retention structure 12f located in the first hemimandible P1, and a fourth retention structure 14f, a fifth retention structure 15f located in the second hemimandible P2. The first retention structure 11f is closer to the dental midline P than the second retention structure 12f, and the fourth retention structure 14f is closer to the dental midline P than the fifth retention structure 15f.

[0088] The first retention structure 11f and the fourth retention structure 14f are both located on the dental midline P and are one structure. That is, the number of the multiple retention structures 10f at this time is three, and the number of the retention structures 10f can be reduced while ensuring the limiting effect.

[0089] As Figures 18 to 20 shown, in the third form, the first retention structure 11g and the second retention structure 12g of the first hemimaxilla P1 are both located in the anterior tooth area. The first retention structure 11g connects the first lingual surface 1012g and the second lingual surface 1022g, and the second retention structure 12g connects the first buccal surface 1011g and the second buccal surface 1021g. That is, the first retention structure 11g and the second retention structure 12g are arranged at intervals in the mesiodistal direction x, and the moment generated by the cooperation of the first retention structure 11g and the second retention structure 12g mainly restricts the rotation of the first dental appliance 101g and the second dental appliance 102g relative to the first rotation axis and the second rotation axis. The first rotation axis extends along the mesiodistal direction x, and the second rotation axis extends along the buccolingual direction y.

[0090] The multiple retention structures 10g further include a fourth retention structure 14g and a fifth retention structure 15g located in the second hemimaxilla P2. The fourth retention structure 14g is closer to the dental midline P than the fifth retention structure 15g.

[0091] Both the fourth retention structure 14g and the fifth retention structure 15g are located in the anterior tooth area, and the fourth retention structure 14g connects the first lingual surface 1012g and the second lingual surface 1022g, and the fifth retention structure 15g connects the first buccal surface 1011g and the second buccal surface 1021g. However, this is not limited thereto, and the fourth retention structure 14g and the fifth retention structure 15g can also be arranged in other areas.

[0092] The first retention structure 11g and the second retention structure 12g of the third form are both located in the anterior tooth area, that is, there is no retention structure in the posterior tooth area. Thus, the influence of the retention structure on the orthodontics of the posterior tooth area can be reduced.

[0093] As Figures 21 to 23 shown, in the fourth form, the first retention structure 11h and the second retention structure 12h of the first hemimaxilla P1 are both located in the posterior tooth area. The first retention structure 11h connects the first lingual surface 1012h and the second lingual surface 1022h, and the second retention structure 12h connects the first buccal surface 1011h and the second buccal surface 1021h. That is, the first retention structure 11h and the second retention structure 12h are arranged at intervals in the mesiodistal direction x, and the moment generated by the cooperation of the first retention structure 11h and the second retention structure 12h mainly restricts the rotation of the first dental appliance 101h and the second dental appliance 102h relative to the first rotation axis and the second rotation axis. The first rotation axis extends along the mesiodistal direction x, and the second rotation axis extends along the buccolingual direction y.

[0094] The multiple retention structures 10h further include a fourth retention structure 14h and a fifth retention structure 15h located on the second hemi - arch P2. The fourth retention structure 14h is closer to the dental mid - line P than the fifth retention structure 15h.

[0095] Both the fourth retention structure 14h and the fifth retention structure 15h are located in the posterior tooth area. The fourth retention structure 14h connects the first lingual surface 1012h and the second lingual surface 1022h, and the fifth retention structure 15h connects the first buccal surface 1011h and the second buccal surface 1021h. However, this is not limiting, and the fourth retention structure 14h and the fifth retention structure 15h can also be arranged in other areas.

[0096] Both the first retention structure 11h and the second retention structure 12h of the fourth form are located in the posterior tooth area, that is, there is no retention structure in the anterior tooth area. In this way, the influence of the retention structure on the orthodontics of the anterior tooth area can be reduced.

[0097] It should be noted that in addition to the various forms of the above - mentioned first specific embodiment and second specific embodiment, other forms may also be included. For example, the first hemi - arch P1 has two retention structures, and both retention structures connect two lingual surfaces; or the first hemi - arch P1 has three retention structures, two retention structures connect two lingual surfaces, and one retention structure connects two buccal surfaces; or the first hemi - arch P1 has two retention structures, and the retention structure connecting two buccal surfaces is closer to the dental mid - line than the retention structure connecting two lingual surfaces, etc.

[0098] Optionally, in combination with Figure 24 , each retention structure 10 includes at least two bases 17 and a limiting part 18 connecting at least two bases 17.

[0099] At least two bases 17 are located on the first buccal surface 1011 and the second buccal surface 1021, or at least two bases 17 are located on the first lingual surface 1012 and the second lingual surface 1022. The connection between the limiting part 18 and the bases 17 is an elastic connection or a rigid connection.

[0100] The number of bases 17 is even or odd, and the direction of the connection line between adjacent bases 17 can be determined according to the actual situation. Here, an example is given that each retention structure 10 includes two bases 17, but this is not limiting.

[0101] The base 17 is a hook - shaped structure, a buckle - shaped structure, a dental brace slot, a tubular structure or a groove - shaped structure, and the limiting part 18 is an annular elastic member, a rigid arch wire, a plate - shaped structure or a C - shaped structure. In this way, an elastic connection or a rigid connection between the base 17 and the limiting part 18 is achieved.

[0102] Here, "bracelet slotting" refers to, for example, a slotted structure formed by cutting a part of the bracelet. The slotted structure can be set corresponding to the teeth, or the slotted structure can be set corresponding to the gums; "tubular structure or grooved structure" refers to, for example, a structure that is inserted and cooperated with a rigid arch wire.

[0103] Optionally, in combination with Figure 24 , taking the base 17 as the hook structure 17 and the limiting part 18 as the elastic part 18 as an example, that is, each retention structure 10 includes two hook structures 17 and an elastic part 18 connecting the two hook structures 17. The two hook structures 17 are respectively located on the first buccal surface 1011 and the second buccal surface 1021, or the two hook structures 17 are respectively located on the first lingual surface 1021 and the second lingual surface 1022. The extending direction of the elastic part 18 is parallel to or inclined to the gingival occlusal surface direction z. Here, taking the extending direction of the elastic part 18 being substantially parallel to the gingival occlusal surface direction z as an example.

[0104] When the first bracelet 101 and the second bracelet 102 are in a closed state, the elastic part 18 is in a deformed state and generates a pre-tightening force, and the pre-tightening force can be used to limit the relative movement between the first bracelet 101 and the second bracelet 102.

[0105] Specifically, when the first bracelet 101 and the second bracelet 102 are in a closed state, the elastic part 18 is already in a deformed state. At this time, the elastic part 18 can already limit the relative movement between the first bracelet 101 and the second bracelet 102. When the first bracelet 101 and the second bracelet 102 move relatively and force the first bracelet 101 and the second bracelet 102 to separate from each other, if the force forcing the separation is greater than the pre-tightening force in the closed state, then this force will drive the elastic part 18 to further deform. Since the deformation degree of the elastic part 18 is greater, a greater pre-tightening force will be generated to further limit the relative movement between the first bracelet 101 and the second bracelet 102.

[0106] The pre-tightening force makes the first bracelet 101 and the second bracelet 102 completely close together and still will not separate under a certain vertical disturbance, avoiding the reciprocating movement or loosening of the first bracelet 101 and the second bracelet 102.

[0107] Optionally, in combination with Figure 25 and Figure 26 , the dental component 100 further includes a horizontal retention structure 103 connecting the first occlusal surface 1013 and the second occlusal surface 1023. The horizontal retention structure 103 limits the relative movement between the first bracelet 101 and the second bracelet 102 in the first plane, and the first plane is perpendicular to the gingival occlusal surface direction z.

[0108] "Relative movement" includes relative translation and relative rotation, that is, the horizontal retention structure 103 is used to restrict the relative translation and relative rotation of the first dental appliance 101 and the second dental appliance 102 in the first plane formed in the mesiodistal direction x and the buccolingual direction y.

[0109] The horizontal retention structure 103 includes a recessed structure 1031 and a protruding structure 1032 that cooperate with each other. One of the recessed structure 1031 and the protruding structure 1032 is located on the first occlusal surface 1013, and the other is located on the second occlusal surface 1023. The recessed structure 1031 and the protruding structure 1032 cooperate with each other to restrict the relative translation and relative rotation of the first dental appliance 101 and the second dental appliance 102 in the first plane.

[0110] Here, the recessed structure 1031 is a recessed structure formed by a Z-shaped protrusion located on the first occlusal surface 1013, and the protruding structure 1032 is two elongated protrusions arranged at intervals on the second occlusal surface 1023. The cooperation between the recessed structure 1031 and the protruding structure 1032 can be regarded as the cooperation of two protrusions.

[0111] When the first dental appliance 101 and the second dental appliance 102 move relative to each other, the pre-tightening force generated by the elastic member 18 can restrict this relative movement. The design of the pre-tightening force can avoid the problem that the first dental appliance 101 and the second dental appliance 102 cannot be properly retained due to the deformation of the recessed structure 1031 and the protruding structure 1032 during use.

[0112] In summary, the present utility model restricts the relative rotation and relative translation of the first dental appliance 101 and the second dental appliance 102 through the cooperation of the first retention structure 11 and the second retention structure 12, and thus can effectively control the relative position between the first dental appliance 101 and the second dental appliance 102. When the relative position between the first dental appliance 101 and the second dental appliance 102 is relatively stable, the orthodontic effect can be effectively improved, such as in the application scenario of jaw position adjustment.
