[0053] 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.

[0054] Referring to Figures 1 to 4, this application provides a dental system 100.

[0055] The dental system 100 includes a force-applying platform 10 having a first point of action A1, a second point of action A2 spaced apart from the force-applying platform 10, and a connector 20 connecting the first point of action A1 and the second point of action A2.

[0056] When the dental system 100 is worn in the oral cavity, the maxillary teeth T1 and mandibular teeth T2 clamp the force application platform 10, the second point of action A2 directly or indirectly contacts the teeth, and the connector 20 generates a force between the first point of action A1 and the second point of action A2.

[0057] When the connector 20 generates a force between the first point of action A1 and the second point of action A2, the force can be transmitted to the teeth through the second point of action A2 to achieve orthodontic treatment, such as molar distalization, tooth intrusion or elongation, tooth rotation, etc., and the force application platform 10 can act as a support to provide the force at this time.

[0058] In this embodiment, the force application platform 10 is clamped between the maxillary tooth T1 and the mandibular tooth T2, which will not cause additional discomfort to the patient. At this time, the position of the force application platform 10 in the oral cavity is stable, which can effectively increase the anchorage and provide a stable force.

[0059] The structure of the force-applying platform 10 can take many forms, including:

[0060] Referring to Figures 1 to 4, in the first form, the force-applying platform 10 includes two interconnected shells 11 and 12. When the dental system 100 is worn into the oral cavity, the two shells 11 and 12 are respectively fitted onto the maxillary tooth T1 and the mandibular tooth T2.

[0061] Taking two shell-shaped bodies 11 and 12 as an example, the first shell-shaped body 11 fitted onto the maxillary tooth T1 and the second shell-shaped body 12 fitted onto the mandibular tooth T2 respectively, the maxillary tooth T1 supports the first shell-shaped body 11 and the mandibular tooth T2 supports the second shell-shaped body 12, and the first shell-shaped body 11 and the second shell-shaped body 12 are connected to each other. At this time, the force-applying platform 10 covers the maxillary tooth T1 and the mandibular tooth T2, and the force-applying platform 10 is stably fixed in the oral cavity by the joint support of the maxillary tooth T1 and the mandibular tooth T2.

[0062] "Force application platform 10 covers maxillary tooth T1 and mandibular tooth T2" means that the force application platform 10 extends to the buccal and / or lingual surfaces of the teeth, and the force application platform 10 can directly or indirectly contact the buccal and / or lingual surfaces of the teeth, the same below.

[0063] Optionally, the force-applying platform 10 includes a retaining structure connecting the two shells 11 and 12, which restricts the relative movement of the two shells 11 and 12.

[0064] The retention structure can be at least one of the following: mechanical retention structure, adhesive retention structure, welded retention structure, magnetic retention structure. Mechanical retention structure refers to a structure that achieves mutual restriction through mutual cooperation of physical structures, such as concave-convex fit, snap-fit, embedding, sleeve, riveting, etc.

[0065] The retention structure may be located at the two occlusal surfaces of the two shells 11 and 12 facing each other, and / or located in the area of ​​the buccal or lingual surface of the corresponding teeth of the two shells 11 and 12.

[0066] The fixation structure restricts the relative motion of the two shells 11 and 12 to zero degrees of freedom. That is, the fixation structure can restrict the relative movement and relative rotation of the two shells 11 and 12 in all dimensions, which can improve the overall stability of the force application platform 10. However, it is not limited to this. The fixation structure can also restrict the relative motion of the two shells 11 and 12 in some dimensions.

[0067] Referring to Figures 5 and 6, in the second form, the force-applying platform 10a includes a shell 11a, which is worn by one of the maxillary teeth T1 and mandibular teeth T2 when the dental system 100a is worn in the oral cavity, while the other occludes the shell 11a.

[0068] Taking the shell-like body 11a fitted onto the maxillary tooth T1 as an example, the maxillary tooth T1 supports the shell-like body 11a, and the occlusal surface of the mandibular tooth T2 bites the shell-like body 11a. At this time, the force-applying platform 10a wraps around the maxillary tooth T1 but does not wrap around the mandibular tooth T2. The force-applying platform 10a is stably fixed in the oral cavity by the support of the maxillary tooth T1 and the occlusion of the mandibular tooth T2.

[0069] To improve the stability of the fit between the mandibular tooth T2 and the force application platform 10a, a retention structure, such as a concave-convex fit structure, can be added between the mandibular tooth T2 and the force application platform 10a.

[0070] Referring to Figures 7 and 8, in the third form, the force-applying platform 10b is an intermediate structure. When the dental system 100b is worn into the oral cavity, the intermediate structure is located in the space formed by the upper occlusal surface of the maxillary tooth T1 and the lower occlusal surface of the mandibular tooth T2.

[0071] The force application platform 10b is located in the space formed by the upper occlusal surface and the lower occlusal surface. That is, the force application platform 10b does not cover the maxillary tooth T1 and the mandibular tooth T2. The force application platform 10b is stably fixed in the oral cavity by the joint occlusion of the maxillary tooth T1 and the mandibular tooth T2.

[0072] To improve the stability of the fit between the maxillary tooth T1, the mandibular tooth T2 and the force application platform 10b, retention structures, such as concave-convex fit structures, can be added between the maxillary tooth T1 and the force application platform 10b, and between the mandibular tooth T2 and the force application platform 10b.

[0073] Optionally, in the first and second forms of the shell-like body described above, taking the first shell-like body 11 of the first form as an example, the first shell-like body 11 includes an extension 111 extending to the gingival region (see Figure 10), and the first point of action A1 is located in the extension 111. In this way, the setting area of ​​the first point of action A1 can be increased to provide force more effectively.

[0074] The first shell 11 includes a shell body and a flexible structure located on the inner wall of the shell body. When the first shell 11 is worn on the teeth, the flexible structure can be squeezed and deformed to better adapt to the patient's dentition and can also fix the force application platform 10 more stably in the oral cavity.

[0075] The flexible structure can be bonded to the inner wall through methods such as bonding, welding, and fusion.

[0076] The first shell 11 is provided for a portion or all of a single jaw tooth. That is, the first shell 11 can cover a portion of the maxillary tooth T1, or the first shell 11 can cover all of the maxillary tooth T1, depending on the actual situation.

[0077] The first shell 11 has a window 112. When the dental system 100 is worn into the oral cavity, the window 112 exposes the second point of action A2. The connector 20 can contact the second point of action A2 through the window 112 and apply force to the second point of action A2.

[0078] When the first shell 11 encloses a portion of the maxillary tooth T1, the area of ​​the maxillary tooth T1 not enclosed by the first shell 11 can be considered as a window 112.

[0079] The descriptions of the first type of second shell 12 and the second type of shell 11a can be found in the description of the first shell 11 mentioned above, and will not be repeated here.

[0080] There are many examples of how the force-applying platform and the teeth can be coupled.

[0081] In the first example, referring to Figures 1 to 4, the force application platform is the first type of force application platform 10 mentioned above, that is, the force application platform 10 includes two shell-like bodies 11 and 12, and the force application platform 10 cooperates with the teeth that are not wearing any orthodontic components.

[0082] Each shell 11, 12 has a cavity that matches the teeth. When the dental system 100 is worn into the oral cavity, the inner wall of each cavity directly contacts the teeth. The "inner wall of the cavity" is the solid structure that surrounds and forms the cavity.

[0083] Here, when the shells 11 and 12 include flexible structures, the cavity is a space enclosed by the flexible structures, that is, when the dental system 100 is worn into the oral cavity, the flexible structures directly contact the teeth.

[0084] Specifically, the first shell 11 has a first cavity S1 that matches the maxillary tooth T1, and the second shell 12 has a second cavity S2 that matches the mandibular tooth T2. When the dental system 100 is worn in the oral cavity, the first cavity S1 wraps around the maxillary tooth T1, and the inner wall of the first cavity S1 directly contacts the tooth. The second cavity S2 wraps around the mandibular tooth T2, and the inner wall of the second cavity S2 directly contacts the tooth.

[0085] The first cavity S1 has a design amount for orthodontic treatment. When the first shell 11 is worn on the maxillary tooth T1, the design amount can realize the movement and rotation of the maxillary tooth T1. That is, in addition to serving as anchorage, the first shell 11 itself can also play an orthodontic role. However, it is not limited to this, and the first cavity S1 may also have no design amount.

[0086] The description of the second cavity S2 can be found in the description of the first cavity S1, and will not be repeated here.

[0087] A window 112 can be formed at the first shell 11, exposing the tooth surface. The second point of action A2 is located on the tooth surface, that is, the second point of action A2 directly contacts the tooth. The window can also be set at the second shell 12.

[0088] In this example, the first shell 11 and the second shell 12 directly engage with the teeth, and the first shell 11 and the second shell 12 can be stably engaged with the teeth, which greatly improves the stability of the entire force application platform 10 in the oral cavity.

[0089] In other embodiments, the force application platform 10a of the second form or the force application platform 10b of the aforementioned third form may cooperate with teeth that are not wearing any orthodontic components.

[0090] In the second example, the force application platform is the force application platform 10 of the first type mentioned above, that is, the force application platform 10 includes two shell-like bodies 11 and 12, and the force application platform 10 cooperates with the teeth wearing orthodontic brackets.

[0091] In this example, the entire or partial area of ​​the tooth surface has orthodontic brackets, and the second point of action A2 is located at the orthodontic bracket on the tooth surface, that is, the second point of action A2 indirectly contacts the tooth, or the second point of action A2 avoids the orthodontic bracket and is located directly on the tooth surface, that is, the second point of action A2 directly contacts the tooth.

[0092] Optionally, windows may be formed at shells 11 and 12 to expose part of the orthodontic bracket. The exposed orthodontic bracket can generate a second point of action A2. Areas of shells 11 and 12 that do not correspond to the orthodontic bracket can directly contact the teeth to improve the stability of the fit between shells 11 and 12 and the teeth, but this is not a limitation.

[0093] In other embodiments, the force-applying platform 10a of the second form or the force-applying platform 10b of the third form may cooperate with the teeth wearing orthodontic brackets.

[0094] In the third example, referring to Figure 9, the force application platform is the force application platform 10 of the first type mentioned above, that is, the force application platform 10 includes two shell-like bodies 11 and 12, and the force application platform 10 cooperates with the teeth wearing the invisible aligner 30.

[0095] The dental system 100 also includes at least one clear aligner 30. When the dental system 100 is worn in the oral cavity, each clear aligner 30 is fitted onto a single tooth, and the shells 11 and 12 are fitted onto the side of the clear aligner 30 away from the tooth.

[0096] The invisible aligner 30 has a design range for correcting teeth. When the invisible aligner 30 is worn on a single tooth (upper tooth T1 or lower tooth T2), this design range can enable the tooth to move, rotate, etc.

[0097] The clear aligner 30 is worn on a single tooth. The shells 11 and 12 have cavities and fit together with the outside of the clear aligner 30 through the cavities. At this time, the shells 11 and 12 indirectly contact the single tooth through the clear aligner 30.

[0098] Optionally, the dental system 100 may include two clear aligners 30 that respectively fit the maxillary tooth T1 and the mandibular tooth T2, with two shells 11 and 12 respectively fitted on the outside of the two clear aligners 30. Alternatively, the dental system 100 may include only one clear aligner 30, with one of the two shells 11 and 12 fitted on the outside of the clear aligner 30 and the other fitted directly on the tooth.

[0099] Shells 11 and 12 can be perfectly matched with the corresponding clear aligner 30, or there may be differences between shells 11 and 12 and the corresponding clear aligner 30. It is only necessary to ensure that there is a certain limiting effect between shells 11 and 12 and clear aligner 30. In this case, shells 11 and 12 can be stably fixed in the oral cavity by clear aligner 30 and upper and lower teeth T2.

[0100] When the second point of action A2 is located on the side with the clear aligner 30, the second point of action A2 is located on the surface of the clear aligner 30 away from the teeth, that is, the second point of action A2 indirectly contacts the teeth.

[0101] Optionally, windows can be formed at shell 11 and 12 to expose part of the clear aligner 30, and the exposed clear aligner 30 can generate a second point of action A2.

[0102] In other embodiments, the force application platform 10a of the second form or the force application platform 10b of the third form described above may cooperate with the teeth wearing the invisible aligner 30.

[0103] Optionally, referring to Figures 1 to 4, the connector 20 includes a base 21 fixed to a first point of action A1, a mounting base 22 fixed to a second point of action A2, and an intermediate member 23 connecting the base 21 and the mounting base 22. The intermediate member 23 and the base 21 are elastically or rigidly connected, and the intermediate member 23 and the mounting base 22 are elastically or rigidly connected.

[0104] "The intermediate component 23 and the base 21 are elastically connected" can mean that at least one of the intermediate component 23 and the base 21 is a deformable elastic structure, while "the intermediate component 23 and the base 21 are rigidly connected" can mean that both the intermediate component 23 and the base 21 are non-deformable structures.

[0105] Similarly, "the intermediate component 23 and the mounting base 22 are elastically connected" can mean that at least one of the intermediate component 23 and the mounting base 22 is a deformable elastic structure, while "the intermediate component 23 and the mounting base 22 are rigidly connected" can mean that both the intermediate component 23 and the mounting base 22 are non-deformable structures.

[0106] The force generated by the connector 20 is transmitted between the base 21 and the first point of action A1 and the intermediate part 23, and between the mounting base 22 and the second point of action A2 and the intermediate part 23, which facilitates the installation of the connector 20 and allows for stable control of the force transmission.

[0107] The force generated by the connector 20 is ultimately applied to the second point of action A2 to achieve orthodontic treatment. The force on the second point of action A2 may include a pulling force away from the second point of action A2 and a pushing force toward the second point of action A2. Both the pulling force and the pushing force can be added to the second point of action A2 through the mounting base 22.

[0108] In other embodiments, the base 21 or mounting base 22 may be omitted, and the force may be transmitted directly at the first point of action A1 or the second point of action A2.

[0109] For example, the mounting base 22 can be removed so that the connector 20 acts directly on the second point of action A2.

[0110] The connector 20 is a rigid structure that connects to the second point of action A2. The force generated by the connector 20 is directed toward the second point of action A2. That is, the force generated by the connector 20 is a pushing force. The connector 20 pushes the second point of action A2 to achieve orthodontic treatment.

[0111] Specifically, the connector 20 can be a rigid archwire. One end of the rigid archwire directly abuts against the second point of action A2 and applies force to the tooth. When the second point of action A2 directly contacts the tooth, the second point of action A2 can be a point on the tooth surface, and the connector 20 directly abuts against that point and applies force to the tooth.

[0112] Optionally, the base 21 can be a hook-shaped structure, a buckle-shaped structure, a slotted shell, a tubular structure, or a groove-shaped structure; the mounting base 22 can be a hook-shaped structure, a buckle-shaped structure, a slotted orthodontic appliance, a tubular structure, or a groove-shaped structure; and the intermediate component 23 can be a ring-shaped elastic component or a rigid archwire.

[0113] Here, "shell-shaped slotting" refers to the slotted structure formed by cutting a portion of the shell when the force application platform has a shell. The slotted structure can be set to correspond to the teeth or the gums. "Orthodontic appliance slotting" refers to the slotted structure formed by cutting a portion of the invisible orthodontic appliance 30 when the dental system has an invisible orthodontic appliance 30. The slotted structure can be set to correspond to the teeth or the gums.

[0114] The base 21 and the intermediate part 23 are fixedly connected or detachably connected, and the mounting base 22 and the intermediate part 23 are fixedly connected or detachably connected.

[0115] The base 21 and the force-applying platform 10 are integrally formed, or the base 21 and the force-applying platform 10 are connected by snap-fit, adhesive, welding or riveting.

[0116] Optionally, the base 21 and mounting base 22 connected to the same intermediate component 23 are located in the same jaw, that is, the base 21 and mounting base 22 at both ends of the same intermediate component 23 are simultaneously set to the maxilla or simultaneously set to the mandible.

[0117] The base 21 and mounting base 22 connected to the same intermediate component 23 are located in different jaws, that is, one of the base 21 and mounting base 22 at both ends of the same intermediate component 23 is set for the maxilla, and the other is set for the mandible. The specific location can be determined according to the position of the tooth to be treated, the direction and magnitude of the required force, etc.

[0118] Optionally, the base 21 is provided on the lingual or buccal side of the force application platform 10, and the mounting seat 22 is provided on the buccal or lingual side of the tooth.

[0119] The base 21 and the mounting base 22 may be located simultaneously on the buccal side of the tooth, and the intermediate member 23 connecting the base 21 and the mounting base 22 may also be located on the buccal side of the tooth; or, the base 21 and the mounting base 22 may be located simultaneously on the lingual side of the tooth, and the intermediate member 23 connecting the base 21 and the mounting base 22 may also be located on the lingual side of the tooth; or, one of the base 21 and the mounting base 22 may be located on the lingual side of the tooth, and the other may be located on the buccal side of the tooth, with the intermediate member 23 passing through the occlusal surface of the tooth to connect the base 21 and the mounting base 22.

[0120] Optionally, the base 21, mounting base 22, and intermediate component 23 are not limited to a one-to-one fit.

[0121] For example, a dental system 100 includes a base 21 and a plurality of mounting seats 22. One end of a plurality of intermediate components 23 is connected to a plurality of mounting seats 22, and the other end of a plurality of intermediate components 23 is connected to a base 21, that is, a base 21 is used in conjunction with a plurality of mounting seats 22.

[0122] Alternatively, the dental system 100 includes a mounting base 22 and multiple bases 21, with one end of multiple intermediate components 23 connected to the multiple bases 21 respectively, and the other end of each of the multiple intermediate components 23 connected to a mounting base 22, that is, a mounting base 22 is used in conjunction with multiple bases 21.

[0123] A specific embodiment of the dental system 100 is described with reference to Figures 1 to 4.

[0124] In this specific embodiment, the dental system 100 is used in the oral cavity. The dental system 100 includes a force application platform 10 and a connector 20. The force application platform 10 includes two shell-shaped bodies 11 and 12 that are connected to each other and respectively cooperate with the maxillary tooth T1 and the mandibular tooth T2. The connector 20 includes a mounting base 22 independent of the force application platform 10, a base 21 located on the force application platform 10, and an intermediate member 23 connecting the mounting base 22 and the base 21.

[0125] When the dental system 100 is worn in the oral cavity, the force application platform 10 is fitted onto the maxillary tooth T1 and the mandibular tooth T2 through two shell-like bodies 11 and 12. The mounting base 22, independent of the force application platform 10, directly or indirectly contacts the teeth. The intermediate component 23 generates a force between the base 21 and the mounting base 22. This force can be directly or indirectly transmitted to the teeth through the mounting base 22 to achieve orthodontic treatment, such as molar distalization, tooth intrusion or elongation, tooth rotation, etc. At this time, the force application platform 10 can act as a support to provide force.

[0126] In this embodiment, the force application platform 10 is fitted onto the maxillary teeth T1 and mandibular teeth T2 through two interconnected shell-like bodies 11 and 12. This does not cause additional discomfort to the patient. The maxillary teeth T1 and mandibular teeth T2 simultaneously support the force application platform 10, which can be stably fixed in the oral cavity. As anchorage, the force application platform 10 can provide a stable force for orthodontic treatment.

[0127] One of the two shell-like bodies 11 and 12 matches all maxillary teeth T1, and the other matches all mandibular teeth T2.

[0128] Here, we take two shell-shaped bodies 11 and 12 as examples, the first shell 11 and the second shell 12. The first shell 11 has a first cavity S1 that matches all the maxillary teeth T1, and the second shell 12 has a second cavity S2 that matches all the mandibular teeth T2. When the dental system 100 is worn in the oral cavity, the first cavity S1 covers all the maxillary teeth T1, and the second cavity S2 covers all the mandibular teeth T2, which can greatly improve the stability of the force application platform 10 in the oral cavity.

[0129] The interiors of the first cavity S1 and the second cavity S2 can be equipped with flexible structures to increase the stability of the two shells 11 and 12 in conjunction with the teeth, thereby further improving the stability of the force application platform 10 in the oral cavity.

[0130] The first shell 11 includes an extension 111 extending to the gingival region, and a base 21 is located in the extension 111. In this way, the installation area of ​​the base 21 can be increased, and the lever arm of the required force can be increased as much as possible within the limited installation area of ​​the first shell 11, thereby effectively increasing the required force.

[0131] The first shell 11 includes a window 112, which is used to expose the mounting 22 when the dental system 100 is worn into the oral cavity.

[0132] The description of the second shell 12 can be found in the description of the first shell 11, and will not be repeated here. The extension and the window can be provided at the first shell 11 and / or the second shell 12 as needed.

[0133] Optionally, one of the base 21 and the mounting base 22 corresponds to the maxillary tooth T1, and the other corresponds to the mandibular tooth T2; or, both the base 21 and the mounting base 22 correspond to the maxillary tooth T1; or, both the base 21 and the mounting base 22 correspond to the mandibular tooth T2. That is, the base 21 and the mounting base 22 can be set in the same jaw, or the base 21 and the mounting base 22 can be set in different jaws.

[0134] Both the base 21 and the mounting base 22 are provided on the buccal side of the teeth, which facilitates the connection between the intermediate part 23 and the base 21 and the mounting base 22.

[0135] Below, we will introduce several specific application scenarios of the Dental System 100.

[0136] Figures 1 to 4 illustrate the application scenarios of tooth elongation correction.

[0137] The force application platform 10 includes two shell-shaped bodies 11 and 12 connected to each other. The two shell-shaped bodies 11 and 12 include a first shell-shaped body 11 and a second shell-shaped body 12. The first shell-shaped body 11 includes a window 112. The base 21 is located in the second shell-shaped body 12. When the dental system 100 is worn in the oral cavity, the mounting seat 22 is directly connected to the tooth at the window 112. The intermediate part 23 extends approximately along the gingival occlusal surface direction z.

[0138] Both the base 21 and the mounting base 22 are provided on the buccal side of the tooth. Both the base 21 and the mounting base 22 are snap-fit ​​structures. The intermediate part 23 is an annular elastic element, that is, the intermediate part 23 is elastically connected to the base 21 and the intermediate part 23 is elastically connected to the mounting base 22. The base 21 is bonded to the force application platform 10 and the mounting base 22 is bonded to the tooth.

[0139] When the dental system 100 is worn in the oral cavity, the intermediate part 23 deforms and generates a pulling force F that is away from the mounting base 22 and approximately parallel to the gingival occlusal surface z. This pulling force F acts on the tooth through the mounting base 22, thereby achieving the elongation correction of the tooth.

[0140] In other embodiments, the extension direction of the intermediate member 23 may have an acute angle with the gingival occlusal surface direction z. In this case, the component of the force generated by the intermediate member 23 along the gingival occlusal surface direction z can be used as the pulling force for elongation correction.

[0141] When the force applied by the intermediate component 23 to the mounting base 22 is a pushing force, the tooth can be depressed for orthodontic treatment.

[0142] Figures 10 to 12 illustrate the application scenarios of tooth intrusion correction.

[0143] The force-applying platform 10c includes two shell-shaped bodies 11c and 12c connected to each other. The two shell-shaped bodies 11c and 12c include a first shell-shaped body 11c and a second shell-shaped body 12c. The first shell-shaped body 11c includes a window 112c. The connector 20c includes two bases 21c located on the proximal and distal sides of the window 112c.

[0144] When the dental system 100c is worn into the oral cavity, the mounting base 22c is directly connected to the tooth at the window 112c, the two bases 21c are located in the first shell 11c, the two bases 21c are farther away from the second shell 12c than the mounting base 22c, and the two intermediate parts 23c are respectively connected to the two bases 21c and simultaneously connected to the mounting base 22c.

[0145] The two bases 21c and the mounting base 22c are all positioned on the buccal side of the teeth, and the two bases 21c, the two intermediate parts 23c and the mounting base 22c roughly form a "V" shape.

[0146] Both the base 21c and the mounting base 22c are snap-fit ​​structures, and the intermediate part 23c is an annular elastic part. That is, the intermediate part 23c is elastically connected to the base 21c, and the intermediate part 23c is elastically connected to the mounting base 22c. The two bases 21c are bonded to the force-applying platform 10c, and the mounting base 22c is bonded to the teeth.

[0147] When the dental system 100c is worn in the oral cavity, the two intermediate parts 23c deform to generate a first pulling force F1 and a second pulling force F2 that are tilted relative to the occlusal surface of the gums in the z direction. The first pulling force F1 and the second pulling force F2 act on the tooth through the mounting seat 22c, thereby achieving the intrusion orthodontic treatment of the tooth.

[0148] Specifically, the first pulling force F1 includes a first component force F11 extending along the gingival occlusal surface z, and the second pulling force F2 includes a second component force F21 extending along the gingival occlusal surface z. The first component force F11 and the second component force F21 act to depress the tooth.

[0149] The first shell 11c includes an extension 111c extending to the gingival region. Taking two extensions 111c as an example, the two bases 21c are located at the two extensions 111c respectively. At this time, with the magnitudes of the pulling force F1 and the second pulling force F2 remaining unchanged, the lever arms corresponding to the first component force F11 and the second component force F21 increase, thereby effectively increasing the first component force F11 and the second component force F21, which enhances the indentation effect on the teeth.

[0150] In other embodiments, the position of the mounting base remains unchanged, the two bases can be moved down to the second shell 12c, and the two intermediate parts are respectively connected to the two bases and simultaneously connected to the mounting base.

[0151] The "V"-shaped opening formed between the two bases, two intermediate parts, and one mounting base is changed to face downwards, and the force generated at this time can achieve the elongation of the tooth.

[0152] Figures 13 and 14 illustrate the application scenarios of orthodontic treatment.

[0153] The force-applying platform 10d includes two shell-shaped bodies 11d and 12d that are connected to each other. The two shell-shaped bodies 11d and 12d include a first shell-shaped body 11d and a second shell-shaped body 12d. The first shell-shaped body 11d includes a window 112d. The connector 20d includes two bases 21d, a mounting base 22d and two intermediate parts 23d.

[0154] Two bases 21d are located on the first shell 11d and the second shell 12d respectively. When the dental system 100d is worn into the oral cavity, the mounting base 22d is directly connected to the tooth at the window 112d. Two intermediate parts 23d are connected to the two bases 21d respectively and are also connected to the mounting base 22d.

[0155] The first shell 11d includes an extension 111d extending to the gingival region, and a base 21d located in the first shell 11d is located in the extension 111d.

[0156] Both bases 21d and mounting base 22d are positioned corresponding to the buccal side of the tooth. The two bases 21d are buckle-shaped structures, and the mounting base 22d is a hook-shaped structure with bidirectional traction. That is, the mounting base 22d has two hooks 221d, and two intermediate parts 23d are respectively fitted onto the two hooks 221d. The intermediate parts 23d are annular elastic elements, that is, the intermediate parts 23d and the bases 21d are elastically connected, and the intermediate parts 23d and the mounting base 22d are elastically connected. The two bases 21d are bonded to the force application platform 10d, and the mounting base 22d is bonded to the tooth.

[0157] When the dental system 100d is worn in the oral cavity, the two intermediate parts 23d deform to generate a first pulling force F1 and a second pulling force F2 that are tilted relative to the gingival occlusal surface z. The first pulling force F1 is directed towards the upper left, and the second pulling force F2 is directed towards the lower right. The first pulling force F1 and the second pulling force F2 act on the teeth through the mounting base 22d, and the teeth are pulled in two directions to achieve orthodontic treatment.

[0158] Figures 15 and 16 illustrate the application scenarios of tooth translation orthodontics.

[0159] The force-applying platform 10e includes two shell-shaped bodies 11e and 12e connected to each other. The two shell-shaped bodies 11e and 12e include a first shell-shaped body 11e and a second shell-shaped body 12e. The first shell-shaped body 11e includes a window 112e. The connector 20e includes a base 21e, a mounting base 22e and an intermediate member 23e. The base 21e is located on the first shell-shaped body 11e.

[0160] When the dental system 100e is worn in the oral cavity, the mounting base 22e is directly connected to the tooth at the window 112e, the base 21e is located on the distal side of the mounting base 22e, and the intermediate part 23e extends approximately in the mesiodistal direction x.

[0161] Both the base 21e and the mounting base 22e are provided on the buccal side of the tooth. The base 21e has a snap-like structure, the mounting base 22e has a hook-like structure, and the intermediate part 23e is an annular elastic element. That is, the intermediate part 23e and the base 21e are elastically connected, and the intermediate part 23e and the mounting base 22e are elastically connected. The base 21e is bonded to the force application platform 10e, and the mounting base 22e is bonded to the tooth.

[0162] The first shell 11e includes an extension 111e extending to the gingival region, and a base 21e located on the first shell 11e is located on the extension 111e.

[0163] When the dental system 100e is worn in the oral cavity, the intermediate part 23e deforms and generates a pulling force F that is away from the mounting seat 22e and approximately parallel to the mesiodistal direction x. This pulling force F acts on the tooth through the mounting seat 22e, thereby achieving distal translation of the tooth.

[0164] In other embodiments, the extension direction of the intermediate member 23e may have an acute angle with the mesiodistal direction x. In this case, the component of the force generated by the intermediate member 23e along the mesiodistal direction x can be used as the pulling force for translational correction.

[0165] When the base is located on the mesial side of the mounting base, mesial translation of the tooth can be achieved.

[0166] Figure 17 illustrates the application scenarios for orthodontic treatment of tooth rotation.

[0167] The force-applying platform 10f includes two interconnected shell-shaped bodies 11f and 12f. The two shell-shaped bodies 11f and 12f include a first shell-shaped body 11f and a second shell-shaped body 12f. The first shell-shaped body 11f includes a window 112f. The connector 20f includes a base 21f, a mounting base 22f and an intermediate member 23f. The base 21f is located on the first shell-shaped body 11f.

[0168] When the dental system 100f is worn into the oral cavity, the mounting base 22f is directly connected to the tooth at the window 112f, and the base 21f is located on the mesial side of the mounting base 22f.

[0169] Both the base 21f and the mounting base 22f are provided on the buccal side of the tooth. Both the base 21f and the mounting base 22f are tubular or grooved structures, such as buccal tubes. The intermediate part 23f is a rigid archwire. The intermediate part 23f is rigidly connected to the base 21f and rigidly connected to the mounting base 22f. The base 21f is bonded to the force application platform 10f and the mounting base 22f is bonded to the tooth.

[0170] When the dental system 100f is worn into the mouth, the intermediate component 23f generates a pulling force that can cause the teeth to rotate.

[0171] In summary, the force application platform 10 of this application is held between the maxillary tooth T1 and the mandibular tooth T2 without causing additional discomfort to the patient. Moreover, the position of the force application platform 10 in the oral cavity is stable, which can effectively increase anchorage and provide a stable force.
