[0036] When the first invisible mouthguard 10 and the second invisible mouthguard 20 are in the occlusion state, the guide plate 30 abuts against the first contact surface 13 to realize the depression, the forward guide or the retraction of the first dental arch T1.

[0037] The guide plate 30 of the embodiment is arranged corresponding to the interproximal space P of the second dental arch T2, and when the first invisible mouthguard 10 and the second invisible mouthguard 20 are in the occlusion state, no matter which area of the first contact surface 13 the guide plate 30 abuts against, the guide plate 30 can apply a force to the first contact surface 13, and the first contact surface 13 can transfer the force to the first dental arch T1 to realize the depression, the forward guide or the retraction of the first dental arch T1.

[0038] Compared with the guide plate in the prior art, the design of the guide plate 30 of the embodiment is not limited by the relative position of the upper and lower dental arches, the mounting surface form of the added guide plate and the like, and the design of the guide plate 30 is more free and personalized, which can greatly reduce the design difficulty of the guide plate 30.

[0039] In addition, even if there is a design error or installation error of the guide plate 30, the guide plate 30 can still abut against the first contact surface 13, thereby still playing a correction effect. In this way, the design precision requirement of the guide plate 30 can be reduced, and the design difficulty of the guide plate 30 is further reduced.

[0040] Optionally, the invisible aligner assembly 100 in the embodiment can be applied to a deep overbite correction scene or a jaw position correction scene, and different numbers, positions or shapes of guide plates 30 can be designed for different correction stages or correction steps to achieve different correction targets.

[0041] Optionally, the first dental arch T1 in the embodiment is taken as the lower jaw, and the second dental arch T2 is taken as the upper jaw. That is, when the guide plate 30 abuts against the first contact surface 13, the lower jaw can be lowered, forward guided or retracted, but the application is not limited thereto.

[0042] Optionally, the guide plate 30 can be integrally formed with the second invisible aligner 20, or the guide plate 30 is independently formed and installed on the second invisible aligner 20.

[0043] When the guide plate 30 is integrally formed with the second invisible aligner 20, the guide plate 30 can have a containing cavity S that communicates with the second cavity S2. In this case, the junction between the containing cavity S and the second cavity S2 can be regarded as the mounting surface 40, and the mounting surface 40 is a virtual surface.

[0044] The invisible aligner assembly 100 can further include a filler in the containing cavity S.

[0045] When the guide plate 30 is independently formed and installed on the second invisible aligner 20, the part of the second invisible aligner 20 corresponding to the interproximal space P forms the mounting surface 40, and the mounting surface 40 is a solid surface. The guide plate 30 can be connected to the mounting surface 40 by adhesion, welding or the like.

[0046] Optionally, the mounting surface 40 includes an inner mounting surface 41 located on the second lingual surface 22, an outer mounting surface 42 located on the second labial surface 21, and a top mounting surface 43 located on the second contact surface 23. The guide plate 30 is connected to at least one of the inner mounting surface 41, the outer mounting surface 42 and the top mounting surface 43.

[0047] The interproximal space P between the adjacent two teeth is approximately in the shape of “Π”. The mounting surface 40 corresponding to the interproximal space P is also approximately in the shape of “Π”. The mounting surface 40 is sequentially connected by the inner mounting surface 41, the top mounting surface 43 and the outer mounting surface 42.

[0048] For the same mounting surface 40, there can be only one guide plate 30, and the guide plate 30 is connected to one of the inner mounting surface 41, the top mounting surface 43 and the outer mounting surface 42.

[0049] Alternatively, for the same installation surface 40, two guide plates 30 can be provided, and the two guide plates 30 are connected to two of the inner installation surface 41, the top installation surface 43 and the outer installation surface 42, for example, the two guide plates 30 are connected to the inner installation surface 41 and the top installation surface 43 respectively, and the two guide plates 30 can be connected, but are not limited thereto.

[0050] Alternatively, for the same installation surface 40, three guide plates 30 can be provided, and the three guide plates 30 are connected to the inner installation surface 41, the top installation surface 43 and the outer installation surface 42 respectively, and the three guide plates 30 can be connected, but are not limited thereto.

[0051] Alternatively, when the first invisible aligner 10 and the second invisible aligner 20 are in the occlusion state, if the first invisible aligner 10 is closer to the labial side than the second invisible aligner 20 and the distance between the two is larger, the guide plate 30 can be arranged on the outer installation surface 42 to facilitate the guide plate 30 abutting the first contact surface 13; if the first invisible aligner 10 is closer to the lingual side than the second invisible aligner 20 and the distance between the two is larger, the guide plate 30 can be arranged on the inner installation surface 41 to facilitate the guide plate 30 abutting the first contact surface 13; if the distance between the first invisible aligner 10 and the second invisible aligner 20 is smaller, the guide plate 30 can be arranged on the top installation surface 43 to facilitate the guide plate 30 abutting the first contact surface 13, but are not limited thereto, and the specific arrangement position of the guide plate 30 can be determined according to actual needs.

[0052] Alternatively, when the guide plate 30 is connected to the inner installation surface 41, the guide plate 30 extends towards the lingual side (away from one side of the second cavity S2); when the guide plate 30 is connected to the outer installation surface 42, the guide plate 30 extends towards the labial side (away from one side of the second cavity S2); when the guide plate 30 is connected to the top installation surface 43, the guide plate 30 extends towards the direction of the first contact surface 13 (away from one side of the second cavity S2).

[0053] Alternatively, when the guide plate 30 is connected to the inner installation surface 41, the guide plate 30 protrudes out of the second contact surface 23, that is, the guide plate 30 extending towards the lingual side also extends towards the direction of the first contact surface 13, and the guide plate 30 protruding out of the second contact surface 23 can adjust the opening degree between the first dental arch T1 and the second dental arch T2.

[0054] Alternatively, when the guide plate 30 is connected to the inner installation surface 41, the guide plate 30 can also not protrude out of the second contact surface 23, which can facilitate hiding the guide plate 30.

[0055] Alternatively, when the guide plate 30 is connected to the outer installation surface 42, the guide plate 30 protrudes out of the second contact surface 23, that is, the guide plate 30 extending towards the labial side also extends towards the direction of the first contact surface 13, and the guide plate 30 protruding out of the second contact surface 23 can adjust the opening degree between the first dental arch T1 and the second dental arch T2.

[0056] Alternatively, the guide plate 30 can not protrude out of the second contact surface 23 when the guide plate 30 is connected to the outer mounting surface 42.

[0057] Optionally, the guide plate 30 has a cross section parallel to the reference plane, and the cross section has a tendency to increase in area in the first direction X when the guide plate 30 is connected to the inner mounting surface 41 or the outer mounting surface 42, the first direction X being the direction in which the second contact surface 23 faces the gingival end G, and the reference plane being perpendicular to the first direction X.

[0058] In the first direction X, the cross section has a tendency to increase in area, and the end of the guide plate 30 close to the gingival end G has a large area, i.e. the end of the guide plate 30 does not converge, which can effectively increase the strength of the entire guide plate 30 and avoid deformation or collapse of the guide plate 30 during abutment against the first contact surface 13.

[0059] In addition, when the guide plate 30 is integrally formed with the second invisible aligner 20, the guide plate 30 and the second invisible aligner 20 can be formed by a hot stamping film forming process, and since the end of the guide plate 30 close to the gingival end G has a large area, the difficulty of the demolding step in the hot stamping film forming process can be effectively reduced.

[0060] Optionally, the guide plate 30 includes an abutment surface 31 abutting against the first contact surface 13, and the abutment surface 31 is substantially parallel to the reference plane, which can effectively increase the contact area between the abutment surface 31 and the first contact surface 13.

[0061] Alternatively, the abutment surface 31 is inclined relative to the reference plane, i.e. the abutment surface 31 can be a bevel, an arc surface, or the like, which can play a guiding role.

[0062] In addition, a friction structure can be formed on the abutment surface 31 to increase the stability of the cooperation between the abutment surface 31 and the first contact surface 13.

[0063] Optionally, the guide plate 30 includes a mesial surface 32, a distal surface 33, and a connecting surface 34 connecting the mesial surface 32 and the distal surface 33, and the mesial surface 32, the distal surface 33, and the connecting surface 34 surround to form the guide plate 30 in a block shape.

[0064] The connecting surface 34 and the mesial surface 32 are smoothly connected, and the connecting surface 34 and the distal surface 33 are smoothly connected, which can avoid the presence of edges that affect the wearing comfort on the one hand, and can avoid the presence of edges that form stress concentration at the edges on the other hand, and the stress concentration is likely to affect the stability of the guide plate 30.

[0065] The abutment surface 31 can be located at the connecting surface 34, or the abutment surface 31 can also be a transition region between the mesial surface 32 and the distal surface 33, in which case the transition region does not have the connecting surface 34, and the connecting surface 34 connects the mesial surface 32 and the distal surface 33 in other regions.

[0066] Optionally, the mesial surface 32 of the guide plate 30 is a guide slope, and / or the distal surface 33 of the guide plate 30 is a guide slope.

[0067] When the guide plate 30 contacts the first contact surface 13, the mesial surface 32 or the distal surface 33 interferes with a part of the first contact surface 13, and the inclined mesial surface 32 or the distal surface 33 can guide the guide plate 30 to the proper position during the interference.

[0068] During the design of the guide plate 30, the mesial surface 32 or the distal surface 33 can be designed to make the guide plate 30 and the first contact surface 13 abut each other at the target position, thereby improving the treatment effect.

[0069] Optionally, the guide plate 30 is a narrow structure (the guide plate 30 is not a long guide plate extending to cover multiple teeth), and one guide plate 30 is arranged corresponding to one interproximal space P of the second dentition T2.

[0070] For example, the mounting surface 42 corresponds to the interproximal space P between the adjacent Nth tooth and the N+1th tooth, the Nth tooth is mesial to the N+1th tooth, the mesial surface of the guide plate 30 extends to the region of the Nth tooth and does not exceed the mesial surface of the Nth tooth, and / or the distal surface of the guide plate 30 extends to the region of the N+1th tooth and does not exceed the distal surface of the N+1th tooth, that is, the guide plate 30 corresponds to one interproximal space P and does not exceed the Nth tooth and the N+1th tooth in the mesial-distal direction, and the guide plate 30 only slightly extends to the region corresponding to the Nth tooth or the N+1th tooth to improve the overall volume of the guide plate 30, thereby improving the strength of the guide plate 30.

[0071] Optionally, the first contact surface 13 includes a plurality of first regions 131 corresponding to a plurality of interproximal spaces P of the first dentition T1, a plurality of second regions 132 corresponding to a plurality of anterior tooth incisal edges B of the first dentition T1, and a plurality of third regions 133 corresponding to a plurality of posterior tooth occlusal surfaces C of the first dentition T1.

[0072] The first contact surface 13 can be formed by connecting a plurality of first regions 131, a plurality of second regions 132, and a plurality of third regions 133, one first region 131 corresponding to one interproximal space P, one second region 132 corresponding to one anterior tooth incisal edge B, and one third region 133 corresponding to one posterior tooth occlusal surface C.

[0073] The guide plate 30 is narrow, and when the first invisible aligner 10 and the second invisible aligner 20 are in the occlusion state, one guide plate 30 abuts one of the first region 131, the second region 132, and the third region 133.

[0074] When one guide plate 30 abuts the first region 131, the first region 131 is a relatively recessed region of the first contact surface 13, and the guide plate 30 can be stably positioned at the first region 131.

[0075] When one of the guides 30 abuts against the second region 132, the second region 132 corresponds to the relatively small and flat anterior tooth incisal edge B, the guide 30 can move at the second region 132, for example, slide to the adjacent first region 131, but not limited to this, the guide 30 can also be positioned at the second region 132, or the guide 30 is positioned at the second region 132 with the aid of some limiting structure.

[0076] When one of the guides 30 abuts against the third region 133, the third region 133 corresponds to the relatively large posterior tooth occlusal surface C, and the guide 30 can also be stably positioned at the third region 133.

[0077] Optionally, when the guide 30 needs to be positioned at a specific position after abutting against the first contact surface 13, the guide 30 can be guided to the specific position with the aid of the guide slope.

[0078] For example, in the initial design, the guide 30 is designed to correspond to the second region 132, and when the guide 30 abuts against the second region 132, the guide slope of the guide 30 guides the guide 30 to the first region 131, which can be used to realize the anterior guide of the first dental arch T1, but not limited to this.

[0079] Optionally, in the mesiodistal direction, the width of the abutment surface 31 is not greater than the width of the first region 131, which can make the guide 30 be clamped in the first region 131 to improve stability.

[0080] Optionally, the invisible aligner assembly 200 includes two guides 30, the second invisible aligner 20 is divided into a left half and a right half by the dental midline, and the two guides 30 are located in the left half and the right half respectively. The two guides 30 are symmetrically arranged, the design of the two guides 30 can improve the treatment efficiency, and can make the first dental arch T1 bear force uniformly, but not limited to this, the invisible aligner assembly 200 can also include other number of guides 30.

[0081] In summary, the guide 30 of the utility model corresponds to the interproximal space P of the second dental arch T2, and when the first invisible aligner 10 and the second invisible aligner 20 are in the occlusion state, no matter which region of the first contact surface 13 the guide 30 abuts against, the guide 30 can apply force to the first contact surface 13, and the first contact surface 13 can transfer the force to the first dental arch T1 to realize the depression, anterior guide or posterior shrinkage of the first dental arch T1.

[0082] Compared with the guide in the prior art, the design of the guide 30 of the embodiment is not limited by the relative position of the upper and lower dental arches, the mounting surface form of the added guide, and the like, and the design of the guide 30 is more free and personalized, which can greatly reduce the design difficulty of the guide 30.

[0083] In addition, even if the guide plate 30 has design errors or installation errors, the guide plate 30 can still abut against the first contact surface 13, thereby still playing a correction effect, so that the design accuracy requirement of the guide plate 30 can be reduced, and the design difficulty of the guide plate 30 is further reduced.
