Technical Field

[0002] This application relates to the field of orthodontic technology, and more particularly to an invisible braces assembly. Background Technology

[0003] Due to their aesthetic appeal, convenience, and ease of cleaning, invisible braces made of polymer materials are becoming increasingly popular.

[0004] For common clinical cases such as deep overbite, reverse overbite, and locked jaw, invisible braces are often used in conjunction with guide plates to open the bite during orthodontic treatment. They are also accompanied by other auxiliary functions, such as tooth intrusion, mandibular retraction, etc.

[0005] Currently, in order to ensure that the opposing teeth can abut against the guide plate, it is usually necessary to restrict the placement and width of the guide plate, which increases the design difficulty of the guide plate. Summary of the Invention

[0006] The purpose of this application is to provide an invisible braces component that helps improve the contact between the guide plate and the opposing jaw.

[0007] This application provides an invisible braces assembly, including a first invisible brace matching a first jawbone, a second invisible brace matching a second jawbone, and a guide plate. The first invisible brace includes a first labial / buccal surface, a first lingual surface, and a first contact surface connecting the first labial / buccal surface and the first lingual surface. The second invisible brace includes an mounting surface corresponding to the adjacent tooth gap of the second jawbone. The guide plate is connected to the mounting surface. When the first invisible brace and the second invisible brace are in an occlusal state, the guide plate abuts against the first contact surface to achieve depressing, forward guiding, or retraction of the first jawbone.

[0008] Optionally, the second invisible brace includes a second labial / buccal surface, a second lingual surface, and a second contact surface connecting the second labial / buccal surface and the second lingual surface. The mounting surface includes an inner mounting surface located on the second lingual surface, an outer mounting surface located on the second labial / buccal surface, and a top mounting surface located on the second contact surface. The guide plate connects at least one of the inner mounting surface, the outer mounting surface, and the top mounting surface.

[0009] Optionally, when the guide plate is connected to the inner mounting surface, the guide plate protrudes beyond the second contact surface, or the guide plate does not protrude beyond the second contact surface.

[0010] Optionally, when the guide plate is connected to the outer mounting surface, the guide plate protrudes beyond the second contact surface, or the guide plate does not protrude beyond the second contact surface.

[0011] Optionally, the guide plate has a cross-section parallel to the reference plane. When the guide plate is connected to the inner mounting surface or the outer mounting surface, the area of ​​the cross-section tends to increase in a first direction, where the first direction is the direction from the second contact surface toward the gingival end, and the reference plane is perpendicular to the first direction.

[0012] Optionally, the guide plate includes an abutting surface that abuts against the first contact surface, the abutting surface being parallel to a reference plane, or the abutting surface being inclined relative to the reference plane, the reference plane being perpendicular to the direction of the second contact surface toward the gingival end.

[0013] Optionally, the first contact surface includes multiple first regions corresponding to multiple adjacent tooth gaps of the first jaw, multiple second regions corresponding to multiple anterior incisal edges of the first jaw, and multiple third regions corresponding to multiple posterior occlusal surfaces of the first jaw. When the first invisible brace and the second invisible brace are in an occlusal state, a guide plate abuts against one of the first region, the second region, and the third region.

[0014] Optionally, the guide plate includes an abutting surface that abuts against the first contact surface, wherein the width of the abutting surface in the proximal-distal direction is not greater than the width of the first region.

[0015] Optionally, the mounting surface corresponds to the adjacent tooth gap of the Nth tooth and the N+1th tooth, the Nth tooth is located mesial to the N+1th tooth, the mesial surface of the guide plate extends to the area of ​​the Nth tooth but does not exceed the mesial surface of the Nth tooth, and / or the distal surface of the guide plate extends to the area of ​​the N+1th tooth but does not exceed the distal surface of the N+1th tooth.

[0016] Optionally, the near-mid surface of the guide plate is a guide slope, and / or the far-mid surface of the guide plate is a guide slope.

[0017] Optionally, the guide plate includes a mid-surface, a distal-surface, and a connecting surface connecting the mid-surface and the distal-surface, wherein the connecting surface and the mid-surface have a smooth transition, and the connecting surface and the distal-surface have a smooth transition.

[0018] Optionally, the invisible braces assembly includes two guide plates. The second invisible braces are divided into a left half and a right half by the midline of the teeth. The two guide plates are located in the left half and the right half respectively, and the two guide plates are symmetrically arranged.

[0019] Optionally, the guide plate is integrally formed with the second invisible brace.

[0020] Optionally, the second invisible aligner has a cavity for accommodating a second jaw, the guide plate has a receiving cavity that communicates with the cavity, and the invisible aligner assembly further includes a filler located within the receiving cavity.

[0021] Optionally, the first jaw is the mandible and the second jaw is the maxilla.

[0022] Compared with the prior art, the beneficial effects of this application are as follows: the guide plate of the embodiment of this application is set to the adjacent tooth gap of the second jaw. When the first invisible brace and the second invisible brace are in the biting state, the guide plate can apply force to the first contact surface regardless of which area the guide plate abuts against. The first contact surface can transfer the force to the first jaw to achieve the depressing, forward guiding or retraction of the first jaw.

[0023] Compared to guides in the prior art, the design of the guide in this embodiment is not limited by the relative position of the upper and lower jaws or the shape of the mounting surface of the guide. The design of the guide is more free and personalized, which can greatly reduce the design difficulty of the guide.

[0024] In addition, even if there are design or installation errors in the guide plate, the guide plate can still abut against the first contact surface and thus still achieve the corrective effect. This reduces the design precision requirements of the guide plate and further reduces the design difficulty of the guide plate. Attached Figure Description

[0030] The present application will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of this application.

[0031] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Referring to Figures 1 to 5, this application provides an invisible braces assembly 100.

[0033] The invisible braces assembly 100 includes a first invisible braces 10 that matches the first jaw T1, a second invisible braces 20 that matches the second jaw T2, and a guide plate 30.

[0034] The first invisible brace 10 has a first cavity S1 to accommodate the first jaw T1, and the second invisible brace 20 has a second cavity S2 to accommodate the second jaw T2. Both the first invisible brace 10 and the second invisible brace 20 can be made of polymer materials.

[0035] The first invisible brace 10 includes a first labial buccal surface 11, a first lingual surface 12, and a first contact surface 13 connecting the first labial buccal surface 11 and the first lingual surface 12. The first labial buccal surface 11, the first lingual surface 12, and the first contact surface 13 surround and form a first cavity S1.

[0036] The second invisible brace 20 includes a second labial buccal surface 21, a second lingual surface 22, and a second contact surface 23 connecting the second labial buccal surface 21 and the second lingual surface 22. The second labial buccal surface 21, the second lingual surface 22, and the second contact surface 23 surround and form a second cavity S2.

[0037] The second invisible brace 20 includes a mounting surface 40 corresponding to the adjacent tooth gap P of the second jaw T2, and a guide plate 30 is connected to the mounting surface 40.

[0038] When the second invisible brace 20 is worn on the second jaw T2, the guide plate 30 is set to correspond to the adjacent tooth gap P of the second jaw T2.

[0039] When the first invisible brace 10 and the second invisible brace 20 are in an occlusal state, the guide plate 30 abuts against the first contact surface 13 to achieve the depressing, forward guiding or retraction of the first jaw T1.

[0040] In this embodiment, the guide plate 30 is provided corresponding to the adjacent tooth gap P of the second jaw T2. When the first invisible brace 10 and the second invisible brace 20 are in an occlusal state, the guide plate 30 can apply force to the first contact surface 13 regardless of which area the guide plate 30 abuts against. The first contact surface 13 can transfer the force to the first jaw T1 to achieve the depressing, forward guiding, or retraction of the first jaw T1.

[0041] Compared to guides in the prior art, the design of the guide 30 in this embodiment is not limited by the relative position of the upper and lower jaws or the shape of the mounting surface for adding the guide. The design of the guide 30 is more free and personalized, which can greatly reduce the design difficulty of the guide 30.

[0042] In addition, even if there are design errors or installation errors in the guide plate 30, the guide plate 30 can still abut against the first contact surface 13, and thus still achieve the correction effect. In this way, the design accuracy requirements of the guide plate 30 can be reduced, and the design difficulty of the guide plate 30 can be further reduced.

[0043] Optionally, the invisible braces component 100 of this embodiment can be applied to deep overbite correction scenarios or malocclusion correction scenarios, etc. For different correction stages or steps, guides 30 of different numbers, positions or shapes can be designed to achieve different correction goals.

[0044] Optionally, this embodiment takes the first jaw T1 as the mandible and the second jaw T2 as the maxilla as an example. That is, when the guide plate 30 abuts against the first contact surface 13, it can realize the depressing, forward guiding or retraction of the mandible, but it is not limited to this.

[0045] Optionally, the guide plate 30 can be integrally formed with the second invisible braces 20, or the guide plate 30 can be independently formed and installed on the second invisible braces 20.

[0046] When the guide plate 30 is integrally formed with the second invisible dental aligner 20, the guide plate 30 can have a receiving cavity S that connects to the second cavity S2. At this time, the junction area between the receiving cavity S and the second cavity S2 can be regarded as the mounting surface 40, and the mounting surface 40 is a virtual surface.

[0047] The invisible braces assembly 100 may also include a filling material located within the receiving cavity S.

[0048] When the guide plate 30 is an independently molded structure installed on the second invisible brace 20, the portion of the second invisible brace 20 corresponding to the gap P between adjacent teeth forms an installation surface 40. The installation surface 40 is a solid surface, and the guide plate 30 can be connected to the installation surface 40 by means of bonding, welding, etc.

[0049] Optionally, the mounting surface 40 includes an inner mounting surface 41 located on the second tongue surface 22, an outer mounting surface 42 located on the second lip and cheek surface 21, and a top mounting surface 43 located on the second contact surface 23. The guide plate 30 connects to at least one of the inner mounting surface 41, the outer mounting surface 42, and the top mounting surface 43.

[0050] The gap P between two adjacent teeth is roughly in the shape of "Π". The mounting surface 40 corresponding to the gap P is also roughly in the shape of "Π". The mounting surface 40 is formed by connecting the inner mounting surface 41, the top mounting surface 43 and the outer mounting surface 42 in sequence.

[0051] For the same mounting surface 40, there may be only one guide plate 30, which connects to one of the inner mounting surface 41, the top mounting surface 43, and the outer mounting surface 42.

[0052] Alternatively, for the same mounting surface 40, there may be two guide plates 30, which are respectively connected to two of the mounting surfaces 41, top mounting surface 43 and outer mounting surface 42. For example, the two guide plates 30 are respectively connected to the inner mounting surface 41 and top mounting surface 43. The two guide plates 30 can be connected, but are not limited thereto.

[0053] Alternatively, for the same mounting surface 40, there may be three guide plates 30, which are respectively connected to the inner mounting surface 41, the top mounting surface 43 and the outer mounting surface 42. The three guide plates 30 may be connected, but are not limited thereto.

[0054] Optionally, when the first invisible brace 10 and the second invisible brace 20 are in an occlusal state, if the first invisible brace 10 is closer to the labial / buccal side than the second invisible brace 20 and the distance between them is larger, the guide plate 30 can be placed on the outer mounting surface 42 to facilitate the guide plate 30 abutting against the first contact surface 13; if the first invisible brace 10 is closer to the lingual side than the second invisible brace 20 and the distance between them is larger, the guide plate 30 can be placed on the inner mounting surface 41 to facilitate the guide plate 30 abutting against the first contact surface 13; if the distance between the first invisible brace 10 and the second invisible brace 20 is smaller, the guide plate 30 can be placed on the top mounting surface 43 to facilitate the guide plate 30 abutting against the first contact surface 13, but this is not a limitation, and the specific placement of the guide plate 30 can be determined according to actual needs.

[0055] Optionally, when the guide plate 30 is connected to the inner mounting surface 41, the guide plate 30 extends toward the tongue side (the side away from the second cavity S2); when the guide plate 30 is connected to the outer mounting surface 42, the guide plate 30 extends toward the lip / cheek side (the side away from the second cavity S2); when the guide plate 30 is connected to the top mounting surface 43, the guide plate 30 extends toward the direction of the first contact surface 13 (the side away from the second cavity S2).

[0056] Optionally, when the guide plate 30 is connected to the inner mounting surface 41, the guide plate 30 protrudes from the second contact surface 23, that is, the guide plate 30 extending towards the lingual side also extends towards the first contact surface 13. The guide plate 30 protruding from the second contact surface 23 can adjust the degree of opening between the first jaw T1 and the second jaw T2.

[0057] Alternatively, when the guide plate 30 is connected to the inner mounting surface 41, the guide plate 30 may not protrude from the second contact surface 23, which makes it easier to hide the guide plate 30.

[0058] Optionally, when the guide plate 30 is connected to the outer mounting surface 42, the guide plate 30 protrudes from the second contact surface 23, that is, the guide plate 30 extending towards the labial and buccal side also extends towards the first contact surface 13. The guide plate 30 protruding from the second contact surface 23 can adjust the degree of opening between the first jaw T1 and the second jaw T2.

[0059] Alternatively, when the guide plate 30 is connected to the outer mounting surface 42, the guide plate 30 may not protrude from the second contact surface 23.

[0060] Optionally, the guide plate 30 has a cross-section parallel to the reference plane. When the guide plate 30 is connected to the inner mounting surface 41 or the outer mounting surface 42, the area of ​​the cross-section tends to increase in the first direction X. The first direction X is the direction from the second contact surface 23 toward the gingival end G, and the reference plane is perpendicular to the first direction X.

[0061] In the first direction X, the cross-sectional area tends to increase. The end of the guide plate 30 near the gingival end G has a larger area, meaning that the end of the guide plate 30 does not converge. This can effectively increase the strength of the entire guide plate 30 and prevent the guide plate 30 from deforming or collapsing during the process of contacting the first contact surface 13.

[0062] In addition, when the guide plate 30 and the second invisible aligner 20 are integrally formed, the guide plate 30 and the second invisible aligner 20 can be realized by the hot pressing molding process. Since the end area of ​​the guide plate 30 near the gingival end G is large, the difficulty of the demolding step in the hot pressing molding process can be effectively reduced.

[0063] Optionally, the guide plate 30 includes an abutting surface 31 that abuts against the first contact surface 13. The abutting surface 31 is generally parallel to the reference plane, which can effectively increase the contact area between the abutting surface 31 and the first contact surface 13.

[0064] Alternatively, the contact surface 31 may be inclined relative to the reference plane, that is, the contact surface 31 may be a slope, an arc surface, etc., which may serve as a guide.

[0065] In addition, a friction structure can be formed on the abutment surface 31 to increase the stability of the fit between the abutment surface 31 and the first contact surface 13.

[0066] Optionally, the guide plate 30 includes a near-mid surface 32, a far-mid surface 33, and a connecting surface 34 connecting the near-mid surface 32 and the far-mid surface 33. The near-mid surface 32, the far-mid surface 33, and the connecting surface 34 are arranged to form a block-shaped guide plate 30.

[0067] The connecting surface 34 and the near-middle surface 32 have a smooth transition, and the connecting surface 34 and the far-middle surface 33 have a smooth transition. The smooth transition can avoid sharp corners that would affect wearing comfort, and it can also avoid sharp corners that would cause stress concentration at the corners. Stress concentration can easily affect the stability of the guide plate 30.

[0068] The abutting surface 31 may be located at the connecting surface 34, or the abutting surface 31 may be the transition area between the near-middle surface 32 and the far-middle surface 33. In this case, the connecting surface 34 does not exist in the transition area, and the connecting surface 34 connects the near-middle surface 32 and the far-middle surface 33 in other areas.

[0069] Optionally, the near-middle surface 32 of the guide plate 30 is a guide slope, and / or the far-middle surface 33 of the guide plate 30 is a guide slope.

[0070] When the guide plate 30 contacts the first contact surface 13, the near-middle surface 32 or the far-middle surface 33 will interfere with a part of the first contact surface 13. The inclined near-middle surface 32 or the far-middle surface 33 can play a guiding role in the interference process and guide the guide plate 30 to a suitable position.

[0071] During the design process of the guide plate 30, a suitable mesial surface 32 or distal surface 33 can be designed so that the guide plate 30 and the first contact surface 13 can abut against each other at the target position, thereby improving the orthodontic effect.

[0072] Optionally, the guide plate 30 has a narrower structure (the guide plate 30 is not a long guide plate that extends to cover multiple teeth), and one guide plate 30 is set to correspond to one adjacent tooth gap P of the second jaw T2.

[0073] For example, the mounting surface 42 corresponds to the adjacent tooth gap P of the Nth tooth and the N+1th tooth. The Nth tooth is located in the mesial region of the N+1th tooth. The mesial surface of the guide plate 30 extends to the area of ​​the Nth tooth but does not exceed the mesial surface of the Nth tooth, and / or the distal surface of the guide plate 30 extends to the area of ​​the N+1th tooth but does not exceed the distal surface of the N+1th tooth. That is, the guide plate 30 is set for an adjacent tooth gap P and does not exceed the Nth tooth and the N+1th tooth in the mesial-distal direction. The guide plate 30 only slightly extends to the area of ​​the corresponding Nth tooth or the N+1th tooth to increase the overall volume of the guide plate 30, thereby increasing the strength of the guide plate 30.

[0074] Optionally, the first contact surface 13 includes multiple first regions 131 of multiple adjacent tooth gaps P corresponding to the first jaw T1, multiple second regions 132 of multiple anterior incisal edges B corresponding to the first jaw T1, and multiple third regions 133 of multiple posterior occlusal surfaces C corresponding to the first jaw T1.

[0075] The first contact surface 13 can be formed by connecting multiple first regions 131, multiple second regions 132 and multiple third regions 133. One first region 131 corresponds to one adjacent tooth space P, one second region 132 corresponds to one anterior tooth incisal edge B, and one third region 133 corresponds to one posterior tooth occlusal surface C.

[0076] The guide plate 30 is relatively narrow. When the first invisible brace 10 and the second invisible brace 20 are in the biting state, one of the guide plates 30 abuts against one of the first region 131, the second region 132 and the third region 133.

[0077] When a guide plate 30 abuts against the first region 131, the first region 131 is a relatively concave region of the first contact surface 13, and the guide plate 30 can be stably positioned at the first region 131.

[0078] When a guide plate 30 abuts against the second region 132, which corresponds to the relatively small and flat anterior tooth incisal end B, the guide plate 30 may move in the second region 132, for example, by sliding to the adjacent first region 131. However, this is not a limitation. The guide plate 30 may also be positioned in the second region 132, or the guide plate 30 may be positioned in the second region 132 with the assistance of some limiting structures.

[0079] When a guide plate 30 abuts against the third region 133, the third region 133 corresponds to the relatively large posterior tooth occlusal surface C, and the guide plate 30 can be stably positioned in the third region 133.

[0080] Optionally, when the guide plate 30 needs to be positioned in a specific location after it abuts against the first contact surface 13, the guide plate 30 can be guided to the specific location by means of the guide ramp.

[0081] For example, in the initial design, the guide plate 30 is designed to correspond to the second region 132. When the guide plate 30 abuts against the second region 132, the guide slope of the guide plate 30 guides the guide plate 30 to the first region 131, which can be used to achieve the pre-guide of the first tooth T1, but is not limited thereto.

[0082] Optionally, in the near-far direction, the width of the contact surface 31 is not greater than the width of the first region 131, which can make the guide plate 30 snap into the first region 131 to improve stability.

[0083] Optionally, the invisible braces assembly 200 includes two guide plates 30. The second invisible braces 20 is divided into a left half and a right half by the dental midline. The two guide plates 30 are located in the left half and the right half respectively. The two guide plates 30 are symmetrically arranged. The design of the two guide plates 30 can improve the orthodontic efficiency and make the first jaw T1 bear force evenly. However, it is not limited to this. The number of guide plates 30 included in the invisible braces assembly 200 can also be other.

[0084] In summary, the guide plate 30 of this application is set to the adjacent tooth gap P of the second jaw T2. When the first invisible brace 10 and the second invisible brace 20 are in an occlusal state, the guide plate 30 can apply force to the first contact surface 13 regardless of which area the guide plate 30 abuts against. The first contact surface 13 can transfer the force to the first jaw T1 to achieve the depressing, forward guiding or retraction of the first jaw T1.

[0085] Compared to guides in the prior art, the design of the guide 30 in this embodiment is not limited by the relative position of the upper and lower jaws or the shape of the mounting surface for adding the guide. The design of the guide 30 is more free and personalized, which can greatly reduce the design difficulty of the guide 30.

[0086] In addition, even if there are design errors or installation errors in the guide plate 30, the guide plate 30 can still abut against the first contact surface 13, and thus still achieve the correction effect. In this way, the design accuracy requirements of the guide plate 30 can be reduced, and the design difficulty of the guide plate 30 can be further reduced.

[0087] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0088] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application, and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
