[0036] The dental orthodontic appliance 100 comprises an appliance body 101 having a cavity S accommodating teeth, and at least one fixing portion 10 protruding from the appliance body 101 towards a side away from the cavity S.

[0037] The fixing portion 10 has a through hole portion 11, and the insertion end 203 of the functional piece 200 is limited in the through hole portion 11, so that the mutual connection of the dental orthodontic appliance 100 and the functional piece 200 can be achieved, and the position limitation of the functional piece 200 can be achieved by the insertion end 203 being limited in the through hole portion 11.

[0038] The fixing portion 10 comprises a fixing portion body 12 and the through hole portion 11, and the fixing portion body 12 is circumferentially formed to form a cavity S1 communicating with the cavity S.

[0041] Next, various implementation forms of the fixing portion 10 are introduced.

[0042] In combination with Figure 2 and Figure 3In a first implementation form, the dental assembly 300m comprises a dental appliance 100m and a functional piece 200m, the dental appliance 100m being a dental orthodontic appliance 100m.

[0043] In the first implementation form, the dental orthodontic appliance 100m comprises an appliance body 101m having a cavity S for accommodating a tooth and a fixing portion 10m protruding from the appliance body 101m towards a side away from the cavity S, the fixing portion 10m comprising a perforated portion 11m for insertion of the insertion end 203m of the functional piece 200m.

[0044] The fixing portion 10m further comprises a fixing portion body 12m, the fixing portion body 12m surrounding a hollow cavity S1 communicating with the cavity S.

[0045] Optionally, the fixing portion body 12m comprises a peripheral portion 121m and a top portion 122m connected to each other, the peripheral portion 121m being connected to the appliance body 101m, and the peripheral portion 121m and the top portion 122m surrounding the hollow cavity S1.

[0046] The fixing portion body 12m is substantially in a cap shape, a hollow structure in a middle portion of the fixing portion body 12m forming the hollow cavity S1, the fixing portion body 12m being integrally formed with the appliance body 101m, the fixing portion body 12m being simple in forming process and stable in cooperation with the appliance body 101m.

[0047] The perforated portion 11m comprises a first aperture 111m and a second aperture 112m penetrating through the fixing portion body 12m, the first aperture 111m and the second aperture 112m being spaced apart, the first aperture 111m being located at the peripheral portion 121m or the top portion 122m, and the second aperture 112m being located at the peripheral portion 121m or the top portion 122m.

[0048] In the first implementation form, the first aperture 111m and the second aperture 112m are located at the same fixing portion 10m, for example, the first aperture 111m and the second aperture 112m are located at opposite sides of the peripheral portion 121m, specifically, the first aperture 111m is located at a mesial end surface of the fixing portion body 12m, and the second aperture 112m is located at a distal end surface of the fixing portion body 12m, but not limited thereto.

[0050] The functional element 200m is directly fixed to the fixing portion 10m by two insertion ends 203m, and the fixing portion 10m serves as an interface to realize the mutual fixation of the functional element 200m and the dental orthodontic appliance 100m.

[0051] The functional element 200m includes a functional element body 204m and an arch wire 202m connected to the functional element body 204m, and the insertion ends 203m are free ends of the arch wire 202m.

[0052] Optionally, the two insertion ends 203m are two free ends of the arch wire 202m of the same functional element 200m.

[0053] Specifically, the functional element body 204m is located at the middle part of the arch wire 202m, and the arch wire 202m includes two free ends away from the functional element body 204m, i.e., the arch wire 202m includes two parts located on both sides of the functional element body 204m, and the two ends of the two parts away from the functional element body 204m are the two free ends.

[0054] The functional element body 204m may be, for example, a tongue training element, a traction buckle, etc. For example, taking the case where the functional element body 204m is a palatal bead movably sleeved on the arch wire 202m as an example, the palatal bead can be used for tongue training, and the fixing portion 10m can be located on the lingual surface A2 of the appliance body 101m, but the present disclosure is not limited thereto, and in other implementation forms, the fixing portion 10m can also be located on the buccal surface of the appliance body 101m.

[0055] Optionally, the dental assembly 300m further includes two stop portions 2021m connecting the two free ends (i.e., the two insertion ends 203m), and the surrounding area of the first opening 111m and the surrounding area of the second opening 112m are matched with the two stop portions 2021m to limit the movement of the arch wire 202m towards the cavity S1, and the stop portions 2021m are bending regions of the arch wire 202m.

[0056] The two ends of the arch wire 202m away from the functional element body 204m can be bent inward to form the two insertion ends 203m and the two stop portions 2021m, and at this time, the functional element 200m is roughly in a ring structure with an opening formed between the two insertion ends 203m and used for matching the fixing portion body 12m.

[0057] Optionally, the stop portions can also be block structures sleeved on the arch wire 202m, or the two insertion ends 203m can abut against the inner wall or other structures in the cavity S1 to realize the stop.

[0058] In combination with Figure 4 and Figure 5 In the second implementation form, the dental assembly 300n includes a dental instrument 100n and a functional element 200n, and the dental instrument 100n is a dental orthodontic appliance 100n.

[0059] The second implementation form is mainly different from the first implementation form in that the fixing part 10n further comprises an embedded part 13n located in the cavity S1.

[0060] The perforated part 11n further comprises a passage 131n located in the embedded part 13n and communicating with the first opening 111n, and an additional passage 131n' located in the embedded part 13n and communicating with the second opening 112n, one of the two insertion ends 203n passes through the first opening 111n and extends to the passage 131n, and the other passes through the second opening 112n and extends to the additional passage 131n'.

[0061] The embedded part 13n can improve the overall strength of the fixing part 10n, thereby improving the deformation resistance of the fixing part 10n under the action of force; one insertion end 203n passes through the first opening 111n and the passage 131n at the same time, and the other insertion end 203n passes through the second opening 112n and the additional passage 131n' at the same time, that is, the insertion end 203n is connected to the fixing part body 12n and the embedded part 13n at the same time, which can greatly improve the stability of the cooperation between the insertion end 203n and the fixing part 10n, thereby improving the mutual fixing strength between the functional part 200n and the fixing part 10n.

[0062] Optionally, the additional passage 131n' and the passage 131n are in communication with each other, or the additional passage 131n' and the passage 131n are arranged in a staggered manner.

[0063] This implementation form takes the example that the additional passage 131n' and the passage 131n are in communication with each other, that is, the passage 131n communicates the first opening 111n and the second opening 112n, and the two insertion ends 203n pass through the first opening 111n and the second opening 112n and extend to the passage 131n, respectively.

[0064] Optionally, the passage 131n is in a straight line type, but is not limited thereto.

[0065] Optionally, the passage 131n comprises a first passage 1311n close to the first opening 111n and a second passage 1312n connected to the first passage 1311n, and the opening diameter of the first passage 1311n is greater than or equal to the opening diameter of the second passage 1312n.

[0066] That is, in general, the opening diameter of the part close to the first opening 111n in the passage 131n is larger, so that the embedded part 13n can be prevented from being damaged when the first opening 111n is formed at the cavity S1 where the embedded part 13n is installed, of course, the opening diameter of the first passage 1311n can be equal to the opening diameter of the second passage 1312n.

[0067] Similarly, the second channel 1312n further includes a third channel 1313n on the side away from the first channel 1311n, and the third channel 1313n has a larger opening diameter than the second channel 1312n.

[0068] That is, the entire channel 131n at this time has a form of being small in the middle and large at both ends, and the subsequent hole opening process can be avoided to damage the embedded part 13n.

[0069] Optionally, the embedded part 13n is a pre-formed part installed in the cavity S1, and the channel 131n is a structure pre-formed in the embedded part 13n, but the embedded part 13n can also be in other forms, for example, the embedded part 13n is formed by a material filled in the cavity S1.

The surface of the blocking portion 125p away from the cavity S1 cooperates with the stepped portion 142p to limit the movement of the sleeve 14p in the direction towards the cavity S1.

[0076] The side surface of the resistance part 125p away from the cavity S1 is the mesial side surface 1211p of the fixed part body 12p, and the step part 142p is located outside the cavity S1. The step part 142p is a flange structure of the end of the sleeve 14p, and the step part 142p and the mesial side surface 1211p abut each other to limit the sleeve 14p from moving further in the distal direction.

[0102] The first fixed portion 10t is located at the first tooth position T1, and the second fixed portion 10t' is located at the second tooth position T2. The tooth positions between the first tooth position T1 and the second tooth position T2 refer to the tooth positions between the first tooth position T1 and the second tooth position T2. Figure 10 In the embodiment, the number of tooth positions between the first tooth position T1 and the second tooth position T2 is one.

[0103] It should be noted that when the fixed portion is located at the interproximal space, the fixed portion is defined as being located at the relatively outer tooth position. For example, in combination with Figure 11 When the first fixed portion 10t is located at the interproximal space, the first fixed portion 10t is defined as being located at the relatively distal first tooth position T1. When the second fixed portion 10t' is located at the interproximal space, the second fixed portion 10t' is defined as being located at the relatively proximal second tooth position T2. The number of tooth positions between the first tooth position T1 and the second tooth position T2 is two.

[0104] By controlling the distance between the two fixed portions, the stability of the functional element 200t can be effectively improved.

[0105] Optionally, the dental assembly 300t further comprises two stop portions 2021t connecting the two free ends (i.e., the two insertion ends 203t). The surrounding area of the first opening 111t and the surrounding area of the second opening 112t are matched with the two stop portions 2021t to limit the movement of the arch wire 202t towards the cavity S1. The stop portion 2021t is a bending region of the arch wire 202t.

[0106] Optionally, the stop portion can also be a block structure sleeved on the arch wire 202t, or the two insertion ends 203t can abut against the inner wall or other structures in the cavity S1 to achieve the stop.

[0107] Other descriptions of the fifth implementation form can refer to other implementation forms, which will not be repeated here.

[0108] In combination with Figure 13 and Figure 14 In the sixth implementation form, the dental assembly 300u comprises a dental appliance 100u and a functional element 200u. The dental appliance 100u is an orthodontic appliance 100u.

[0109] The sixth implementation form differs from the fifth implementation form mainly in that, in the sixth implementation form, the first opening 111u is located at the peripheral portion 121u of the first fixing portion 10u away from the second fixing portion 10u', the second opening 112u is located at the peripheral portion 121u' of the second fixing portion 10u' away from the first fixing portion 10u, and the first opening 111u and the second opening 112u are located at the outer side regions of the two fixing portions.

[0110] The functional piece 200u includes two insertion ends 203u, which respectively pass through the first opening 111u and the second opening 112u and extend to the cavity S1, that is, one of the two insertion ends 203u is inserted into the cavity S1 of the first fixing portion 10u from one side of the first opening 111u, and the other is inserted into the cavity S1 of the second fixing portion 10u' from one side of the second opening 112u.

[0111] When the distance between the two fixing portions of the fifth implementation form and the sixth implementation form is the same, compared with the fifth implementation form, the length of the arch wire 202u between the first opening 111u and the second opening 112u in the sixth implementation form is relatively longer, the movable range of the palatal bead 204u (that is, the functional piece body 204u) sleeved on the arch wire 202u is wider, and the degree of freedom of tongue training can be further improved.

[0112] Optionally, the number of tooth positions between the two tooth positions corresponding to the first fixing portion 10u and the second fixing portion 10u' is not more than two, and specific reference can be made to the description of the fifth implementation form.

[0113] Optionally, the dental assembly 300u further includes two stop portions 2021u connecting the two free ends (that is, the two insertion ends 203u), and the surrounding regions of the first opening 111u and the second opening 112u are matched with the two stop portions 2021u to limit the movement of the arch wire 202u towards the cavity S1, and the stop portions 2021u are bending regions of the arch wire 202u.

[0114] The two ends of the arch wire 202u away from the functional piece body 204u can be bent inward to form the two insertion ends 203u and the two stop portions 2021u, and at this time, the functional piece 200u is roughly a ring structure with an opening formed between the two insertion ends 203u and used for matching the two fixing portions.

[0115] Optionally, the stop portion can also be a block structure sleeved on the arch wire 202u, or the two insertion ends 203u can abut against the inner wall or other structures in the cavity S1 to achieve the stop.

[0116] Other descriptions of the sixth implementation form can be referred to the other implementation forms, which will not be described here.

[0117] It should be noted that the fifth and sixth implementation forms can be further provided with the embedding part and the sleeve involved in the second to fourth implementation forms, which will not be described here.

[0118] In summary, the fixed part 10 of the utility model has a perforated part 11, and the insertion end 203 of the functional part 200 is limited in the perforated part 11, so that the mutual connection of the dental orthodontic appliance 100 and the functional part 200 can be realized, and the position limitation of the functional part 200 can be realized by limiting the insertion end 203 in the perforated part 11.
