[0056] The present invention 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 invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0057] 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.

[0058] Combination Figures 1 to 5 This utility model provides a dental instrument assembly 100.

[0059] The dental instrument assembly 100 includes a palatal plate 10 that cooperates with each other and at least one force-applying element 20.

[0060] The palatal plate 10 includes a connected palatal plate body 101 and an interface portion 50. The interface portion 50 is used to mount a force-applying member 20. The force-applying member 20 includes a mounting portion 21.

[0061] The interface portion 50 includes a first mating surface S1 having a standard geometric shape. The mounting portion 21 includes a second mating surface S2. The first mating surface S1 and the second mating surface S2 mate with each other so that the mounting portion 21 is mounted to the interface portion 50.

[0062] Optionally, when the force-applying member 20 is installed to the interface portion 50, at least a portion of the first mating surface S1 and the second mating surface S2 are in surface-to-surface contact. That is, at least a portion of the area between the first mating surface S1 and the second mating surface S2 is in surface-to-surface contact.

[0063] "A first mating surface S1 with a standard geometric shape" means that at least a portion of the first mating surface S1 has a standard geometric shape. For example, a portion of the first mating surface S1 may be a standard plane, a standard curved surface, etc. Standard geometric shapes facilitate molding.

[0064] The technical effect of the first mating surface S1 having a standard geometric shape is mainly reflected in the versatility of the palatal plate 10 and the compatibility between the palatal plate 10 and the force-applying component 20.

[0065] Specifically, when the interface portion 50 on the palatal plate 10 has a first mating surface S1 with a standard geometric shape, the second mating surface S2 can easily come into contact with the first mating surface S1 to achieve a relatively stable fit.

[0066] A relatively stable fit between the first mating surface S1 and the second mating surface S2 means that the areas of contact between the first mating surface S1 and the second mating surface S2 are as seamless as possible, thereby improving the installation strength of the force-applying component 20 at the interface 50. However, this does not mean that the first mating surface S1 and the second mating surface S2 are perfectly matched; it is only necessary to ensure that the areas of contact between the surfaces are as seamless as possible.

[0067] Since the first mating surface S1 has a standard geometric shape, it is easy to form a region at the second mating surface S2 that is "seamlessly connected" with at least a portion of the first mating surface S1. For example, assuming that the first mating surface S1 has a standard plane, it is easy to also form a standard plane at the second mating surface S2 to achieve a stable fit with the first mating surface S1, thereby improving the matching between the jaw plate 10 and the force-applying member 20.

[0068] The first mating surface S1 can achieve a relatively stable fit with various second mating surfaces S2. These various second mating surfaces S2 can correspond to various force-applying components 20, and the interface portion 50 can be matched with various force-applying components 20.

[0069] Alternatively, the same interface 50 can be provided on various different palatal plates 10, and the same interface 50 can be matched with various force-applying components 20, so that personalized combinations between various palatal plates 10 and various force-applying components 20 can be realized, greatly improving the versatility of palatal plates 10 and force-applying components 20.

[0070] This embodiment improves the versatility of the palatal plate 10 and the force-applying member 20 by setting the first mating surface S1 of the interface portion 50 to have a standard geometric shape, and also improves the matching between the palatal plate 10 and the force-applying member 20.

[0071] Optionally, the interface portion 50 protrudes from the palatal plate body 101, and the force-applying member 20 can be installed by fitting the mounting portion 21 onto the interface portion 50.

[0072] Alternatively, the interface portion 50 may be recessed relative to the palatal plate body 101, and the force-applying member 20 may be installed by extending the mounting portion 21 into the interface portion 50.

[0073] The interface part 50 and the mounting part 21 can generally be a concave-convex fit structure, but the specific form of the concave-convex fit structure is not limited and can be determined according to specific requirements.

[0074] Optionally, the first mating surface S1 includes the outer surface of the interface portion 50, the mounting portion 21 includes a first recess, and the second mating surface S2 includes an inner surface surrounding the first recess.

[0075] Alternatively, the interface portion 50 includes a second recess, the first mating surface S1 includes an inner surface surrounding the second recess, and the second mating surface S2 includes the outer surface of the mounting portion 21.

[0076] Optionally, the second mating surface S2 has a standard geometry to further improve the versatility of the palatal plate 10 and the force-applying element 20, as well as the compatibility between the palatal plate 10 and the force-applying element 20.

[0077] Optionally, the force-applying component 20 and the interface portion 50 can be detachably fitted to facilitate the replacement of the force-applying component 20. The fitting method between the force-applying component 20 and the interface portion 50 includes snap-fit ​​connection, threaded connection, magnetic connection, etc. However, this is not a limitation, and the force-applying component 20 and the interface portion 50 can also be non-detachably fitted.

[0078] Optionally, at least one force-applying member 20 includes a first force-applying member and a second force-applying member. The two mounting portions 21 of the first force-applying member and the second force-applying member have the same or different second mating surfaces S2, and the two second mating surfaces S2 are adapted to the same first mating surface S1.

[0079] "Mutual adaptation" means that at least some areas of the second mating surface S2 and the first mating surface S1 are in surface contact to achieve a relatively stable fit.

[0080] The force-applying component 20 also includes a mating structure 22. The first force-applying component and the second force-applying component have at least one of the following differences: the mating structure 22 has a different function, the mating structure 22 has a different shape, the mating structure 22 has a different extension direction, and the mating structure 22 has a different design quantity.

[0081] After the palatal plate 10 is installed on the patient's palate E, different force-applying components can be replaced according to different orthodontic needs without removing the palatal plate 10. Different force-applying components can be stably fitted to the interface portion 50 of the palatal plate 10. In this way, the versatility of the palatal plate 10 can be improved and it can be adapted to different orthodontic needs.

[0082] Different force-applying components 20 can be adapted to different orthodontic steps. For example, the first force-applying component corresponds to the Nth orthodontic step, and the second force-applying component corresponds to the N+Mth orthodontic step, where N and M are positive integers.

[0083] Optional, combined Figures 1 to 5 The first mating surface S1 and the second mating surface S2 are completely matched, that is, the first mating surface S1 and the second mating surface S2 have the same shape.

[0084] The interface portion 50 is a protrusion extending from the palatal plate body 101, and the mounting portion 21 is a recess. When the mounting portion 21 is installed at the interface portion 50, approximately all areas of the first mating surface S1 and the second mating surface S2 are in contact.

[0085] Or, combine Figure 6 The second mating surface S2 includes a first region S21 and a second region S22. When the force-applying member 20 is installed to the interface portion 50, the first region S21 and the first mating surface S1 are in surface-to-surface contact, and the second region S22 and the first mating surface S1 are spaced apart from each other.

[0086] exist Figure 6 In the middle, the interface portion 50 is a protrusion extending from the palatine plate body 101. The interface portion 50 is generally a cross-shaped structure, and the first mating surface S1 includes the outer peripheral surface of the cross-shaped structure. The first mating surface S1 includes four standard surfaces S11 located on the outermost side (corresponding to the two outer surfaces on the left and right sides and the two outer surfaces on the top and bottom sides of the cross-shaped structure) and four concave surfaces S12 connecting the adjacent standard surfaces S11.

[0087] The mounting portion 21 is a runway-shaped recess, and the second mating surface S2 includes an inner surface forming the runway-shaped recess. The second mating surface S2 includes a first region S21 that contacts the four standard surfaces S11 and a second region S22 that is spaced apart from the four concave surfaces S12.

[0088] The second region S22 and the concave surface S12 do not interfere with each other. While ensuring the stability of the fit between the interface part 50 and the mounting part 21, it is easy to install the mounting part 21 onto the interface part 50.

[0089] The second mating surface S2 does not need to be perfectly matched with the first mating surface S1, and the second mating surface S2 can have multiple options.

[0090] For example, when the second mating surface S2 has a first region S11 that contacts the four standard surfaces S11 and a second region S22 that is spaced apart from the four concave surfaces S12, a stable fit with the interface portion 50 can be achieved. The second mating surface S2, in addition to... Figure 6 Besides the runway shape, it can also be other shapes, such as rectangles, polygons, etc.

[0091] Since the first mating surface S1 has a standard geometric shape, it can be adapted to various shapes of the second mating surface S2, thereby improving the versatility of the interface part 50.

[0092] Optionally, when the first mating surface S1 and the second mating surface S2 mate with each other, the relative movement of the interface portion 50 and the mounting portion 21 in a certain direction is restricted.

[0093] For example, when the force-applying member 20 is installed on the interface portion 50, the first mating surface S1 and the second mating surface S2 mutually limit each other, thereby restricting the relative movement of the force-applying member 20 and the interface portion 50 in the first direction X and / or the second direction Y.

[0094] The palatal plate body 101 has a bearing surface S of the mounting interface portion 50, with a first direction X that is approximately parallel to the bearing surface S and a second direction Y that is approximately perpendicular to the bearing surface S.

[0095] The mounting part 21 of the force-applying member 20 and the interface part 50 can be implemented in various ways.

[0096] Combination Figures 1 to 5 This is a schematic diagram of the first implementation. In the first implementation, the interface portion 50 protrudes from the palatal plate body 101.

[0097] The interface portion 50 includes a first portion 51 that connects to the bearing surface S, and the first mating surface S1 includes a first outer surface 511 of the first portion 51.

[0098] Mounting part 21 includes a first opening P1, and second mating surface S2 includes a first inner surface 211 surrounding the first opening P1. Mounting part 21 is sleeved onto the outside of the first part 51 through the first opening P1. The first inner surface 211 and the first outer surface 511 mutually limit each other, thereby restricting the relative movement between the force-applying member 20 and the interface part 50 in the first direction X.

[0099] The first part 51 has a cross section in the first direction X that is approximately racetrack shaped, and the first inner surface 211 and the first outer surface 511 are perfectly matched.

[0100] Optionally, the first opening P1 can be a through hole or a blind hole. Here, we take the first opening P1 as a through hole as an example.

[0101] The interface portion 50 also includes a second portion 52, which is connected to the side of the first portion 51 away from the bearing surface S. The second portion 52 protrudes outward from the first portion 51. The second portion 52 is generally hat-shaped and is disposed at the end of the first portion 51 away from the bearing surface S, forming a stepped surface between the second portion 52 and the first portion 51.

[0102] The first mating surface S1 also includes the second outer surface 521 of the second part 52.

[0103] The mounting part 21 also includes a second opening P2 that communicates with the first opening P1, and the second mating surface S2 also includes a second inner surface 212 that surrounds the second opening P2. The mounting part 21 is sleeved on the outside of the second part 52 through the second opening P2, and the second inner surface 212 and the first inner surface 211 mutually limit each other, thereby restricting the relative movement of the force-applying member 20 and the interface part 50 in the first direction X and the second direction Y.

[0104] The second part 52 has a cross section in the first direction X that is approximately racetrack shaped, and the second inner surface 212 and the second outer surface 512 are perfectly matched.

[0105] Optionally, the second opening P2 can be a through hole or a blind hole. Here, we take the second opening P2 as a blind hole as an example.

[0106] In this implementation, the first mating surface S1 and the second mating surface S2 are fully matched, and the first mating surface S1 and the second mating surface S2 mutually limit each other, thereby restricting the relative movement of the force-applying member 20 and the interface part 50 in the first direction X and the second direction Y.

[0107] Combination Figures 7 to 9 This is a schematic diagram of the second implementation. In the second implementation, the interface portion 50 protrudes from the palatal plate body 101.

[0108] The main difference between the second implementation and the first implementation is that the second implementation does not include the second part 52 and the second opening P2.

[0109] In the second implementation, the first opening P1 is a through hole. The first part 51 includes a retention hole 512. The dental instrument assembly 100 also includes a retention member 60, which is a component independent of the force-applying member 20 and the interface part 50.

[0110] The retaining member 60 includes an insertion part 61 and an abutment part 62 connected together. The abutment part 62 protrudes out of the insertion part 61 toward the periphery. The retaining member 60 may be a retaining screw.

[0111] The insertion part 61 passes through the retaining hole 512, and the abutting part 62 abuts against the first part 51 and the mounting part 21 on the side away from the bearing surface S, thereby restricting the relative movement of the force-applying member 20 and the interface part 50 in the second direction Y.

[0112] Specifically, the first part 51 includes an abutment surface 513 away from the bearing surface S. The first opening P1 at the mounting part 21 is a through hole that extends both front and back, and the mounting part 21 includes a hollow annular surface 213 surrounding the opening of the first opening P1 on the side away from the bearing surface S.

[0113] After the mounting part 21 is fitted onto the outside of the first part 51 through the first opening P1, the contact surface 513 is approximately flush with the hollow annular surface 213.

[0114] When the insertion part 61 of the retaining member 60 passes through the retaining hole 512, the abutting part 62, which is larger than the insertion part 61, abuts against the abutting surface 513 and the hollow annular surface 213 at the same time, which can restrict the relative movement of the force-applying member 20 and the interface part 50 in the second direction Y.

[0115] Combination Figure 10 and Figure 11 This is a schematic diagram of the third implementation. In the third implementation, the interface portion 50 is recessed relative to the palatal plate body 101.

[0116] The interface portion 50 is recessed, and the first mating surface S1 is the inner surface of the interface portion 50.

[0117] The mounting part 21 is a protrusion, and the second mating surface S2 is the outer surface of the mounting part 21.

[0118] In this implementation, the first mating surface S1 and the second mating surface S2 are fully matched, and the first mating surface S1 and the second mating surface S2 mutually limit each other, thereby restricting the relative movement of the force-applying member 20 and the interface part 50 in the first direction X.

[0119] Optionally, the palatal plate 10 also includes a fixation hole 1011 located in the palatal plate body 101. The dental instrument assembly 100 also includes an anchorage screw 12. When the dental instrument assembly 100 is in the wearing state, the anchorage screw 12 engages with the fixation hole 1011 to fix the palatal plate 10 to the palate E.

[0120] Optionally, the palatal plate body 101 is used to fix itself to the hard palate. The hard palate refers to the anterior part of the roof of the oral cavity, which is supported by bony structures, thus improving the stability of the palatal plate body 101.

[0121] Optionally, the palatal plate body 101 is a sheet-like structure, and when the dental instrument assembly 100 is in the wearing state, the fixing hole 1101 and the interface portion 50 are symmetrically arranged relative to the palatal midline Z.

[0122] Optionally, at least a portion of the bottom surface 1012 of the palatal plate body 101 facing the palate E is an anatomical surface, and the anatomical surface matches the corresponding shape of the palate E.

[0123] The palate E is non-planar and has an irregular anatomical shape. At least part of the bottom surface 1012 matches the anatomical shape of the palate E, which can improve the stability of the fit between the palatal plate body 101 and the palate E.

[0124] The fixation hole 1011 on the palatal plate body 101 can be located in the anatomical area, allowing the area where the anchorage screw 12 is implanted on the palatal plate body 101 to be perfectly matched with the palate E, improving the fit between this area and the palate E, and thus improving the stability of the palatal plate body 101 fixed to the palate E. Other areas of the palatal plate body 101 may have gaps between them and the palate E to avoid excessive pressure from the palatal plate body 101 on the palate E, but this is not a limitation.

[0125] Optionally, the palatal plate 10 can be made of metal, polymer material, or ceramic. For example, the palatal plate 10 can be made of materials such as titanium alloy, stainless steel, PEEK, or zirconia ceramic. The palatal plate 10 can be formed by machining, 3D printing, injection molding, or other methods.

[0126] The palatal plate 10 can be a customized structure. Specifically, the size and position of the fixing hole 1011, the shape, size and position of the force-applying element 20, and the bottom surface 1012 of the palatal plate body 101 can all be customized.

[0127] Optional, combined Figure 12 and Figure 13 The force-applying component 20 can be an invisible brace 20.

[0128] The invisible braces 20 include a braces body 202 and an extension 203 that connects to the braces body 202 and extends to the palate E.

[0129] The brace body 202 has a cavity S3 for accommodating the tooth T. The brace body 202 includes a first brace body 202a for accommodating the left half of the jaw teeth and a second brace body 202b for accommodating the right half of the jaw teeth, and an extension 203 connects the first brace body 202a and the second brace body 202b. The brace body 202 and the extension 203 can be integrally formed.

[0130] The mounting portion 21 is located at the extension portion 203. When the clear aligners 20 are worn, the mounting portion 21 and the interface portion 50 of the clear aligners 20 cooperate to realize the interaction between the clear aligners 20 and the palatal plate 10. For example, the palatal plate 10 can act as anchorage to assist in the orthodontic process of the clear aligners 20.

[0131] Optional, combined Figure 14 and Figure 15 The dental instrument assembly 100 also includes an orthodontic component 30 that directly or indirectly contacts the tooth T. The force-applying component 20 also includes a mating structure 22. When the dental instrument assembly 100 is in the wearing state, the mating structure 22 interacts with the orthodontic component 30.

[0132] The interaction between the mating structure 22 and the orthodontic component 30 can be realized in various ways.

[0133] In the first implementation, combined Figures 14 to 18 The dental instrument assembly 100 also includes an elastic element 40. When the dental instrument assembly 100 is in the wearing state, the elastic element 40 connects the orthodontic component 30 and the mating structure 22 and generates a force between the mating structure 22 and the orthodontic component 30.

[0134] Optionally, the matching structure 22 can be a traction hook, traction buckle, traction ring, slotted force-applying component, or support nail.

[0135] For example, the force-applying component 20 includes a mounting surface 201 away from the palate E, and the mating structure 22 is a traction hook, traction buckle, or traction ring located on the mounting surface 201. Alternatively, the mating structure 22 is a support pin 12. Alternatively, the force-applying component 20 has a slot, and the mating structure 22 is a slot for the force-applying component.

[0136] Optionally, the orthodontic component 30 may be a traction hook, traction buckle, traction ring, orthodontic bracket, buccal tube, archwire, or aligner slot.

[0137] Optionally, the orthodontic component 30 may be directly fixed to the tooth surface. For example, the orthodontic component 30 may be a traction hook, traction buckle, traction ring, or buccal tube fixed to the tooth surface of a tooth by adhesive bonding. Alternatively, multiple orthodontic brackets may be fixed to the tooth surfaces of multiple teeth by adhesive bonding, and the multiple orthodontic brackets may be connected by archwires. The orthodontic component 30 may be an orthodontic bracket or an archwire.

[0138] Alternatively, the dental instrument assembly 100 may include clear aligners, with orthodontic component 30 fixed to the surface of the clear aligners. For example, orthodontic component 30 may be a traction hook, traction buckle, traction ring, or buccal tube that is adhesively fixed to the surface of the clear aligners. Alternatively, multiple orthodontic brackets may be adhesively fixed to the surface of the clear aligners, and the multiple orthodontic brackets may be connected by archwires; the orthodontic component 30 may be an orthodontic bracket or an archwire.

[0139] Alternatively, the dental instrument assembly 100 may include clear aligners, with the orthodontic component 30 being a part of the clear aligners. For example, the lower edge of the clear aligners may have a aligner slot, which is a notch formed at the edge for mounting the elastic element 40, and the orthodontic component 30 may be the aligner slot.

[0140] Optionally, orthodontic component 30 may be positioned on the lingual side of the teeth, but is not limited thereto.

[0141] Optionally, the elastic element 40 can be a rubber band, rubber chain, spring, or archwire. The elastic element 40 can be a deformation-generating structure, and can be deformed by being stretched or compressed. When the elastic element 40 deforms, it can generate a force between the mating structure 22 and the orthodontic component 30, but is not limited thereto.

[0142] The dental instrument component 100 of the first implementation can have a variety of specific examples.

[0143] In the first specific example, combined Figure 14 and Figure 15 The palatal plate body 101 has two fixing holes 1011 located on the left and right sides of the palatal midline Z, respectively, and the palatal plate body 101 is roughly fixed in the middle of the hard palate. The mating structure 22 is a slotted force-applying component.

[0144] The orthodontic component 30 is a traction hook, and the orthodontic component 30 is directly fixed to the lingual surface of the third molar.

[0145] The orthodontic component 30 is spaced apart from the palatal plate 10, and the orthodontic component 30 is set together with the mating structure 22 in the same jaw.

[0146] The elastic element 40 is a rubber band, and its two ends are respectively sleeved on the mating structure 22 and the orthodontic component 30, which can realize the mesial movement of the third molar.

[0147] In the second specific example, combined Figure 16 The mating structure 22 includes a first mating structure 22a and a second mating structure 22b, and the elastic member 40 connects the first mating structure 22a, the second mating structure 22b and the orthodontic component 30.

[0148] By setting multiple mating structures 22, the force application path can be effectively adjusted, the force intensity optimized, and the traction force adapted to different tooth positions can be achieved. In addition, one or more mating structures 22 can be selectively used to further improve adaptability to different scenarios.

[0149] Optionally, the orthodontic component 30 is a traction buckle, traction hook, or traction ring. The first mating structure 22a and the second mating structure 22b are traction buckles, traction hooks, or traction rings. The orthodontic component 30 is used to act on the teeth to achieve tooth movement along the dental arch, tooth intrusion, elongation, etc.

[0150] The first mating structure 22a, the second mating structure 22b and the orthodontic component 30 are connected by the same elastic element 40.

[0151] The elastic element 40 is a rubber band. The same elastic element 40 includes a first end 41, a second end 42 and an intermediate section 43 located between the first end 41 and the second end 42, which are disposed opposite each other. The first end 41 is connected to the first mating structure 22a, the second end 42 is connected to the orthodontic component 30, and the intermediate section 43 applies force to the second mating structure 22b.

[0152] The same elastic element 40 passes sequentially through the first mating structure 22a, the second mating structure 22b, and the orthodontic component 30. The elastic element 40 has a linear structure as a whole, with the starting point of the elastic element 40 located at the first mating structure 22a and the ending point of the elastic element 40 located at the orthodontic component 30, forming a non-closed linear structure.

[0153] In this specific example, the elastic element 40 forms a traction structure similar to a roller skate, which can effectively adjust the traction distance and traction direction at the orthodontic component 30 to adapt to the traction force requirements of the orthodontic component 30.

[0154] In this specific example, a first point of action G1 is formed between the first end 41 and the first mating structure 22a, a second point of action G2 is formed between the second end 42 and the orthodontic component 30, and a third point of action G3 is formed between the middle section 43 and the second mating structure 22b. The line connecting the first point of action G1, the second point of action G2 and the third point of action G3 is a triangle or a straight line.

[0155] The first point of application G1 can be considered as the force-bearing point formed by the elastic element 40 at the first mating structure 22a; the second point of application G2 can be considered as the force-bearing point formed by the elastic element 40 at the orthodontic component 30; and the third point of application G3 can be considered as the force-bearing point formed by the elastic element 40 at the second mating structure 22b. By adjusting the positions of the first point of application G1, the second point of application G2, and the third point of application G3, the path length and direction between the first point of application G1 and the third point of application G3 can be effectively adjusted, that is, the traction distance and traction direction at the orthodontic component 30 are adjusted to adapt to different traction requirements at the orthodontic component 30.

[0156] This specific example uses the distalization of the second molar as an example, with the orthodontic component 30 positioned at the second molar.

[0157] In a scheme similar to the first specific example, a mating structure 22 can be provided on the distal side of the orthodontic component 30 to achieve distalization of the second molar. For example, the orthodontic component 30 and the second mating structure 22b can be connected by an elastic member 40 to achieve distalization of the second molar. The second molar is located in the terminal region of the entire dentition. Due to the limited space in the jaw, the distance between the second mating structure 22b and the orthodontic component 30 cannot be large, that is, the length between the second point of action G2 and the third point of action G3 is limited, and the distalization traction force on the orthodontic component 30 is also limited.

[0158] In this specific example, the elastic element 40 passes through the first mating structure 22a, the second mating structure 22b, and the orthodontic component 30 in sequence, which can effectively improve the distal traction force on the orthodontic component 30.

[0159] Specifically, in the dental arch direction, the second point of action G2 is located between the first point of action G1 and the third point of action G3. When the line connecting the first point of action G1, the second point of action G2, and the third point of action G3 forms a triangle, the triangle can be an acute triangle. When the line connecting the first point of action G1, the second point of action G2, and the third point of action G3 is a straight line, the straight line can be a reciprocating straight line. This specific example uses the formation of an acute triangle as an example.

[0160] The path length between the first point of action G1 and the second point of action G2 is the sum of the length between the first point of action G1 and the second point of action G2 and the length between the second point of action G2 and the third point of action G3. This can effectively extend the path length of the traction force received by the second point of action G2, that is, extend the traction distance at the orthodontic component 30, and effectively improve the distal traction force received by the orthodontic component 30, so as to improve the distalization efficiency of the second molar.

[0161] In other specific force applications, the magnitude and direction of the traction force can be adjusted by adjusting the positions of the first mating structure 22a and the second mating structure 22b, as well as the extension direction of the elastic element 40, to adapt to different application scenarios, such as adapting to close-range movement scenarios.

[0162] For example, combining Figure 17 The first mating structure 22a, the second mating structure 22b, and the orthodontic component 30 can be set differently to achieve the elongation of the mandibular teeth.

[0163] By setting the orthodontic component 30, the first mating structure 22a and the second mating structure 22b, the traction distance for achieving elongation can be effectively extended, thereby effectively increasing the elongation force on the orthodontic component 30.

[0164] In the third specific example, combined with Figure 18 The mating structure 22 includes a first mating structure 22a and a second mating structure 22b, and the elastic member 40 connects the first mating structure 22a, the second mating structure 22b and the orthodontic component 30.

[0165] The main difference between the third specific example and the second specific example is that the connection method of the elastic element 40 is different.

[0166] In the third specific example, the same elastic element 40 includes a first end 41, a second end 42 disposed opposite to each other, and an intermediate section 43 located between the first end 41 and the second end 42. The first end 41 and the second end 42 are simultaneously connected to one of the orthodontic component 30, the first mating structure 22a, and the second mating structure 22b, and the intermediate section 43 applies force to the other two of the orthodontic component 30, the first mating structure 22a, and the second mating structure 22b.

[0167] The starting point and ending point of the elastic element 40 are located at the same location. For example, the starting point and ending point of the elastic element 40 are both located at the first mating structure 22a. The elastic element 40 passes through the first mating structure 22a, the second mating structure 22b and the orthodontic component 30 in sequence and returns to the first mating structure 22a, forming a closed ring structure.

[0168] In this specific example, a first point of action G1 is formed between the elastic element 40 and the first mating structure 22a, a second point of action G2 is formed between the elastic element 40 and the orthodontic component 30, and a third point of action G3 is formed between the elastic element 40 and the second mating structure 22b. The line connecting the first point of action G1, the second point of action G2 and the third point of action G3 forms a triangle.

[0169] The first point of application G1 can be considered as the force-bearing point formed by the elastic element 40 at the first mating structure 22a. The second point of application G2 can be considered as the force-bearing point formed by the elastic element 40 at the orthodontic component 30. The third point of application G3 can be considered as the force-bearing point formed by the elastic element 40 at the second mating structure 22b. By adjusting the positions of the first point of application G1, the second point of application G2, and the third point of application G3, the path length and direction between the second point of application G2 and the first point of application G1, as well as the path length and direction between the second point of application G2 and the third point of application G3, can be effectively adjusted. That is, the traction distance and traction direction of the two traction forces at the orthodontic component 30 are adjusted to adapt to the different traction requirements at the orthodontic component 30.

[0170] This specific example uses the indentation of the second molar as an example, with the orthodontic component 30 positioned at the second molar.

[0171] The elastic element 40 enables the first mating structure 22a to pull the orthodontic component 30, and simultaneously enables the second mating structure 22b to pull the orthodontic component 30. A portion of the traction force can be used as a pressure force, which can effectively increase the pressure force on the orthodontic component 30.

[0172] Specifically, the length of the line connecting the first point of action G1 and the second point of action G2 is approximately equal to the length of the line connecting the third point of action G3 and the second point of action G2. The second point of action G2 is approximately located on the perpendicular bisector of the line connecting the first point of action G1 and the third point of action G3. The triangle formed by the lines connecting the first point of action G1, the second point of action G2, and the third point of action G3 is approximately an isosceles triangle. This ensures that while increasing the pressure force on the orthodontic component 30, it also minimizes any deviation of the orthodontic component 30 from the dental arch direction, thereby guaranteeing the pressure effect.

[0173] In other specific force applications, the magnitude and direction of the traction force can be adjusted by changing the positions of the first mating structure 22a and the second mating structure 22b, as well as the extension direction of the elastic element 40, to adapt to different application scenarios.

[0174] For example, when the second point of action G2 is located distal to the third point of action G3, the triangle formed by the lines connecting the first point of action G1, the second point of action G2, and the third point of action G3 is approximately an obtuse triangle, which can achieve mesial movement of the second molar.

[0175] In the second implementation, combined Figures 19 to 28 When the dental instrument assembly 100 is in the wearing state, the mating structure 22 comes into contact with the orthodontic component 30 and generates a force.

[0176] This implementation achieves connection and force transmission through direct contact between the mating structure 22 and the orthodontic component 30, which simplifies the force application device, reduces foreign objects in the patient's mouth, and improves the patient's wearing comfort.

[0177] Optionally, the orthodontic component 30 is an invisible aligner, which is used to fit over the T-shaped area of ​​the tooth. Alternatively, the orthodontic component 30 is a component that is directly fixed to the tooth surface. Alternatively, the orthodontic component 30 is a component that is fixed to the surface of the invisible aligner.

[0178] Optionally, the orthodontic component 30 may include an action part 32, and the force-applying component 20 and the orthodontic component 30 may generate a force through the mutual cooperation of the mating structure 22 and the action part 32.

[0179] Optionally, the mating structure 22 and the action part 32 correspond at least to the anchorage tooth setting, and the anchorage tooth is defined as a tooth that will be affected by non-designed amount.

[0180] When orthodontic component 30 is a clear aligner, the clear aligner moves the target teeth through orthodontic force. The orthodontic force corresponds to moving the target teeth in the designed direction. However, during the movement of the target teeth, there is a reaction force in the opposite direction to the orthodontic force.

[0181] Anchorage is a structure that resists the reaction force of orthodontic treatment. Generally, teeth other than the target teeth are used as anchorage teeth. While there is no designed allowance at the anchorage teeth in invisible braces, the reaction force can create an undesigned allowance at the anchorage teeth, causing unwanted movement.

[0182] A key aspect of invisible braces orthodontic treatment is to maximize the movement of the target teeth while minimizing the displacement of undesirable teeth (i.e., anchorage teeth). Therefore, it is necessary to avoid or minimize movement of anchorage teeth in directions other than those designed for movement.

[0183] The mating structure 22 and the action part 32 can be designed for teeth that produce undesigned amounts. The force generated by the contact between the mating structure 22 and the action part 32 can suppress or reduce the undesigned amount.

[0184] Specifically, the mating structure 22 and the action part 32 come into contact to form a contact surface. The direction of the force generated at the contact surface is roughly parallel to and opposite to the direction of movement corresponding to the undesigned amount experienced at the anchorage tooth. By designing a reasonable contact surface position, the influence of undesigned amounts at the anchorage tooth can be effectively suppressed or reduced.

[0185] Optionally, the orthodontic component 30 includes an extension 31, which is a region that is not in close contact with the crown surface, and the actuating part 32 is located in the extension 31.

[0186] The crown surface refers to the exposed surface area of ​​a tooth. It includes the lingual surface A1, the labial / buccal surface A2, and the superior surface A3, which connects the lingual and labial / buccal surfaces A1 and A2. When the tooth is a posterior tooth, the superior surface A3 is the occlusal surface of the posterior tooth; when the tooth is an anterior tooth, the superior surface A3 is the incisal edge of the anterior tooth.

[0187] "Extension 31 is an area that is not in close contact with the crown surface" means that extension 31 is the area below the gingival line L. At this time, extension 31 does not contact the crown surface and extension 31 is not in close contact with the crown surface.

[0188] Alternatively, the extension 31 is located above the gingival line L, but there is a gap between the extension 31 and the crown surface, and the extension 31 does not contact the crown surface.

[0189] Optionally, when the orthodontic component 30 is an invisible brace, the invisible brace includes a brace body and an extension 31. The brace body basically conforms to the crown arrangement in the patient's current or future dentition, the extension 31 is spaced apart from the crowns and is directly or indirectly connected to the brace body, and the active part 32 is located in the extension 31.

[0190] The braces body is a component that conforms to the dental arch, and the extension 31 is spaced apart from the crown. The design of the extension 31 is independent of the braces body; the extension 31 can be designed independently of the braces body, and the design of the extension 31 does not need to take into account the dental arch condition.

[0191] The extension 31 is located on the surface of the braces body, or the extension 31 is an extension of the braces body.

[0192] Optionally, the extension 31 may be provided for at least one of the lingual surface A1 of the tooth, the labial and buccal surface A2 of the tooth, the upper surface A3 of the tooth connecting the lingual surface A1 and the labial and buccal surface A2 of the tooth, the gingival region and the palate E.

[0193] Optionally, when the dental instrument assembly 100 is in the wearing state, a gap S4 is formed between the extension 31 and the jaw, and the force-applying member 20 can extend into the gap S4. The mating structure 22 is located on the side of the force-applying member 20 away from the jaw, and the actuating part 32 is located on the side of the extension 31 facing the gap S4. At this time, the orthodontic component 30 encloses the force-applying member 20.

[0194] Alternatively, when the dental instrument assembly 100 is in the wearing state, the mating structure 22 is located on the side of the force-applying member 20 closer to the jaw, and the actuating part 32 is located on the side of the extension 31 away from the jaw. In this case, the force-applying member 20 encloses the orthodontic component 30.

[0195] Alternatively, when the dental instrument assembly 100 is in the wearing state, the mating structure 22 and the actuating part 32 are arranged adjacent to each other in the mesiodistal direction. For example, the mating structure 22 is located on the distal side of the actuating part 32, or the mating structure 22 is located on the mesiodistal side of the actuating part 32. In this case, the force-applying member 20 and the orthodontic component 30 can be regarded as forming a wrap around each other in the mesiodistal direction.

[0196] The second implementation of the dental instrument component 100 can have a variety of specific examples.

[0197] In the first specific example, combined Figure 19 and Figure 20 Orthodontic component 30 is an invisible brace, which is used to achieve molar distalization.

[0198] The second and third molars in both the left and right halves of the jaw are the target teeth. Orthodontic component 30 is designed to add the amount of material needed to achieve molar distalization to the target teeth. The other teeth in both the left and right halves of the jaw are non-target teeth and can be used as anchorage teeth.

[0199] The extension 31 is located below the gingival line L, and the extension 31 is set roughly corresponding to the gingival or palatal region.

[0200] The mating structure 22 is located on the side of the force-applying member 20 away from the jaw, and the action part 32 is located on the side of the extension part 31 facing the palate E. The mating structure 22 and the action part 32 are in a concave-convex fit.

[0201] The mating structure 22 is a protrusion located on the upper surface of the force-applying member 20. The actuating part 32 is a groove located on the lower surface of the extension 31.

[0202] When the dental instrument assembly 100 is in the wearing state, the orthodontic component 30 is fitted onto all teeth, and the two extensions 31 of the left and right halves of the jaw and the force-applying component 20 are fixed to each other through the concave and convex fit of the action part 32 and the mating structure 22.

[0203] When the orthodontic component 30 moves the second and third molars distally, the orthodontic component 30 will generate a corresponding undesigned amount of mesial movement at other anchorage teeth. These undesigned amounts can be partially or completely transferred to the palatal plate 10 through the extension 31, thereby avoiding unwanted mesial movement of the anchorage teeth.

[0204] The anchorage tooth can be a solid tooth or a vacuolated area, thus the dental instrument assembly 100 of this specific example is suitable for closing the gap by distalization of the molar.

[0205] In the second specific example, combined Figure 21 and Figure 22 The orthodontic component 30 is an invisible brace, which is used to achieve tooth intrusion.

[0206] The main difference between the second specific example and the first specific example is that in the second specific example, the extension 31 and the force-applying member 20 are a concave-convex fit structure, but the concave-convex fit structure achieves tooth depressurization.

[0207] Specifically, the mating structure 22 at the force-applying member 20 is a protrusion, and the action part 32 on the extension 31 is a downward-opening groove. When the groove is fitted onto the protrusion, the force-applying member 20 can pull the extension 31 downward, thereby depressing the teeth.

[0208] Combination Figure 23 and Figure 24 This is a schematic diagram of a dental instrument assembly 100 of a third specific example, which is used to achieve single-jaw arch expansion.

[0209] In the third specific example, the force-applying member 20 extends approximately to the third molar, and the extension 31 is provided corresponding to the four molars from the back. A gap S4 is formed between the extension 31 and the gingiva, and the force-applying member 20 extends into the gap S4.

[0210] The functional part 32 includes a second functional surface 321 extending along the dental arch direction. The second functional surface 321 may be the inner surface of the extension 31 near the jaw.

[0211] The mating structure 22 includes a first working surface 221 extending along the dental arch direction. The first working surface 221 may be the outer surface of the force-applying member 20 away from the jaw.

[0212] The first working surface 221 and the second working surface 321 are in surface contact, restricting the movement of the orthodontic component 30 relative to the force-applying component 20 along a first direction. The first direction is approximately perpendicular to the contact area between the first working surface 221 and the second working surface 321, thus preventing unwanted tilting of the teeth during arch expansion. The force-applying component 20 can provide support for unilateral arch expansion of the posterior teeth by the orthodontic component 30.

[0213] Optionally, along the dental arch direction, the extension 31 and the force-applying member 20 are configured to be in a mutually unrestricted state. In this case, the mesial and distal sides of the extension 31 are through structures, and the extension 31 does not restrict the force-applying member 20 on the mesial or distal sides, but is not restricted by this.

[0214] Combination Figure 25 and Figure 26 This is a schematic diagram of a dental instrument assembly 100 of a fourth specific example, which is used to achieve tooth intrusion.

[0215] The extension 31 is located above the gingival line L, and the extension 31 is set to correspond to the upper end face A3 of the tooth. Here, the extension 31 is set to correspond to the occlusal surface of the posterior tooth.

[0216] The extension 31 is a cavitation structure that protrudes from the occlusal surface of the posterior teeth on the orthodontic component 30, meaning that the extension 31 is not tightly attached to the occlusal surface of the posterior teeth.

[0217] The force-applying member 20 extends above the extension 31, meaning that the force-applying member 20 wraps around the extension 31 at this point.

[0218] The mating structure 22 includes a first working surface 221, which may be the lower surface of the force-applying member 20.

[0219] The functional part 32 includes a second functional surface 321, which may be the upper surface of the extension part 31.

[0220] When the first action surface 221 and the second action surface 321 are in surface contact, the force-applying member 20 can apply force to the teeth through the extension 31, thereby depressing the teeth.

[0221] Combination Figure 27 and Figure 28 This is a schematic diagram of a dental instrument assembly 100 of a fifth specific example, which is used to achieve tooth distalization.

[0222] The extension 31 is located above the gingival line L and is set on the lingual surface A1 of the tooth. Here, the extension 31 is set on the lingual surface of the posterior tooth.

[0223] The extension 31 is a cavitation structure that protrudes from the lingual surface of the posterior teeth on the orthodontic component 30, meaning that the extension 31 is not tightly attached to the lingual surface of the posterior teeth.

[0224] The force-applying member 20 extends to the near-middle side of the extension 31, meaning that the force-applying member 20 and the extension 31 can be considered to form a wrap-around relationship in the near-far-middle direction.

[0225] The mating structure 22 includes a first working surface 221, which may be the distal end face of the mating structure 22.

[0226] The functional part 32 includes a second functional surface 321, which may be the proximal end face of the extension part 31.

[0227] When the first working surface 221 and the second working surface 321 are in surface contact, the mating structure 22 can apply force to the tooth through the extension 31, thereby achieving tooth relocation.

[0228] Combination Figure 29 and Figure 31 The present invention also provides a palatal plate 10, which is used to fix the palate E.

[0229] The palatal plate 10 includes a connected palatal plate body 101 and an interface portion 50, the interface portion 50 including a first mating surface S1 with a standard geometric shape.

[0230] "A first mating surface S1 with a standard geometric shape" means that at least a portion of the first mating surface S1 has a standard geometric shape. For example, a portion of the first mating surface S1 may be a standard plane, a standard curved surface, etc. Standard geometric shapes facilitate molding.

[0231] The technical advantage of the standard geometric shape of the first mating surface S1 is mainly reflected in the versatility of the palatal plate 10 and its compatibility with other components.

[0232] Optionally, the jaw plate 10 is used to mount the force-applying member 20. The force-applying member 20 includes a mounting portion 21, which includes a second mating surface S2. When the force-applying member 20 is mounted to the interface portion 50, at least a portion of the first mating surface S1 and the second mating surface S2 are in surface-to-surface contact.

[0233] When the interface portion 50 on the palatal plate 10 has a first mating surface S1 with a standard geometric shape, the second mating surface S2 can easily come into contact with the first mating surface S1 to achieve a relatively stable fit.

[0234] A relatively stable fit between the first mating surface S1 and the second mating surface S2 means that the areas of contact between the first mating surface S1 and the second mating surface S2 are as seamless as possible, thereby improving the installation strength of the force-applying component 20 at the interface 50. However, this does not mean that the first mating surface S1 and the second mating surface S2 are perfectly matched; it is only necessary to ensure that the areas of contact between the surfaces are as seamless as possible.

[0235] Since the first mating surface S1 has a standard geometric shape, it is easy to form a region at the second mating surface S2 that is "seamlessly connected" with at least a portion of the first mating surface S1. For example, assuming that the first mating surface S1 has a standard plane, it is easy to also form a standard plane at the second mating surface S2 to achieve a stable fit with the first mating surface S1, thereby improving the matching between the jaw plate 10 and the force-applying member 20.

[0236] The first mating surface S1 can achieve a relatively stable fit with various second mating surfaces S2. These various second mating surfaces S2 can correspond to various force-applying components 20, and the interface portion 50 can be matched with various force-applying components 20.

[0237] Alternatively, the same interface 50 can be provided on various different palatal plates 10, and the same interface 50 can be matched with various force-applying components 20, so that personalized combinations between various palatal plates 10 and various force-applying components 20 can be realized, greatly improving the versatility of palatal plates 10 and force-applying components 20.

[0238] Optionally, the first mating surface S1 and the second mating surface S2 are completely matched. Alternatively, the second mating surface S2 includes a first region S21 and a second region S22. When the force-applying member 20 is installed to the interface portion 50, the first region S21 and the first mating surface S1 are in surface-to-surface contact, and the second region S22 and the first mating surface S1 are spaced apart from each other.

[0239] Optionally, the palatal plate 10 is used for detachable mounting of the force-applying element 20, and the palatal plate 10 is configured to adapt to different force-applying elements 20.

[0240] Optionally, different force-applying components 20 may have the same or different second mating surfaces S2.

[0241] Optionally, the force-applying component 20 includes a mating structure 22. Different force-applying components 20 have at least one of the following differences: different functions of the mating structure 22, different shapes of the mating structure 22, different extension directions of the mating structure 22, and different design quantities of the mating structure 22.

[0242] Optionally, different force-applying components 20 correspond to different orthodontic steps. For example, the first force-applying component corresponds to the Nth orthodontic step, and the second force-applying component corresponds to the N+Mth orthodontic step, where N and M are positive integers.

[0243] For a detailed description of the palatal plate 10 in this embodiment, please refer to the description of the dental instrument assembly 100 mentioned above, and it will not be repeated here.

[0244] In summary, by setting the first mating surface S1 of the interface portion 50 to have a standard geometric shape, this utility model can greatly improve the versatility of the palatal plate 10 and the force-applying member 20, and also improve the matching between the palatal plate 10 and the force-applying member 20.
