[0024] The embodiments of this application will be described in detail below with reference to the specific examples shown in the accompanying drawings. However, these embodiments do not limit this application, 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 this application.
[0025] See Figures 1 to 3 One embodiment of this application provides an orthodontic component 10 for correcting a target tooth 30.
[0026] See Figure 3 The orthodontic component 10 includes an orthodontic element 11, which includes an anchorage connection end 111 and a free end 112 disposed opposite to each other. The anchorage connection end 111 is connected to the anchorage element 40, which serves as anchorage.
[0027] Combination Figures 1 to 3 The orthodontic component 11 has a free state and a used state. Figure 2 The dashed line indicates the orthodontic component 11 in its free state. The free state refers to the free end 112 of the orthodontic component 11 being in a free state, separated from the target tooth 30, and not connected to any component or tooth. In this state, the free end 112 exerts no force on the target tooth 30. When the orthodontic component 11 is in its free state, the free end 112 is in the first position. When the orthodontic component 11 is in use, the free end 112 is in the second position and always applies force to the target tooth 30.
[0028] The first and second positions are spaced apart in the lingual-buccal direction, and / or, the first and second positions are spaced apart in the occlusal direction. The lingual-buccal direction refers to the direction from the lingual side to the labial-buccal side.
[0029] Thus, when the orthodontic component 11 is in use, the free end 112 acts on the target tooth 30. The free end 112 of the orthodontic component 11 has a tendency to move from the second position to the first position. When it is blocked by the target tooth 30, under the action of its own repositioning force, the orthodontic component 11 applies a force to the target tooth 30 in the lingual-buccal direction, and / or, the orthodontic component 11 applies a force to the target tooth 30 in the occlusal direction, thereby achieving the orthodontic effect on the target tooth 30.
[0030] In one embodiment, the first position and the second position are spaced apart in the lingual-buccal direction. Thus, when the orthodontic member 11 is in use, the free end 112 of the orthodontic member 11 tends to move from the second position to the first position. When blocked by the target tooth 30, the orthodontic member 11 applies a force to the target tooth 30 in the lingual-buccal direction under the action of its own repositioning force, thereby achieving the orthodontic effect on the target tooth 30.
[0031] In one specific embodiment, the second position is located on the sidewall 33 of the target tooth 30 near the gingival end 31. The gingival end 31 refers to the end of the crown near the gingiva; that is, the second position is located on the sidewall 33 of the crown of the target tooth 30 near the gingiva. Thus, when the orthodontic component 11 is in use, under the action of its own repositioning force, the free end 112 acts on the target tooth 30 and generates a force that causes it to translate, thereby enabling the target tooth 30 to translate.
[0032] In another specific embodiment, the second position is located on the side wall 33 of the target tooth 30 near the incisal edge 32. Thus, when the orthodontic component 11 is in use, under the action of its own resetting force, the free end 112 acts on the target tooth 30 and generates torque, thereby enabling the target tooth 30 to be vertically adjusted.
[0033] In another embodiment, the first position and the second position are spaced apart in the occlusal direction, and the first position is located on the side of the second position away from the occlusal surface of the target tooth 30. Thus, when the orthodontic component 11 is in use, under the action of its own repositioning force, the free end 112 of the orthodontic component 11 tends to move from the second position to the first position, thereby causing the orthodontic component 11 to apply a force towards the gum in the occlusal direction to the target tooth 30, and the free end 112 acts on the target tooth 30 and generates a depressing force, thereby achieving a depressing effect on the target tooth 30.
[0034] In another embodiment, the first position and the second position are spaced apart in both the lingual-buccal direction and the occlusal direction. Thus, when the orthodontic component 11 is in use, under the action of its own repositioning force, the free end 112 of the orthodontic component 11 acts on the target tooth 30 and the applied force has components in both the lingual-buccal direction and the occlusal direction, thereby achieving the correction of the target tooth 30.
[0035] The orthodontic component 11 has a certain degree of rigidity. When the orthodontic component 11 is in use, when the free end 112 is connected to the target tooth 30 by an external force, the orthodontic component 11 deforms and undergoes deformation. The deformed orthodontic component 11 always keeps the free end 112 at the connection position with the target tooth 30. At this time, the orthodontic component 11 remains in a deformed state and always applies a force to the target tooth 30.
[0036] Preferably, the orthodontic component 11 is configured as an integrally bent steel wire or shape memory alloy wire. In this way, when the orthodontic component 11 is in use, it has a tendency to self-reset, thereby allowing the free end 112 to apply force to the target tooth 30.
[0037] See Figures 1 to 2 as well as Figures 5 to 7 The orthodontic component 10 also includes a retention attachment 12 fixedly connected to the target tooth 30. When the orthodontic component 11 is in use, the free end 112 is connected to the retention attachment 12. Thus, when the orthodontic component 11 is in use, the free end 112 tends to move from the second position to the first position and thus exerts force on the target tooth 30 via the retention attachment 12. Especially when there is a gap between the first position and the second position in the occlusal direction, the free end 112 tends to move in the occlusal direction. The free end 112 acts on the retention attachment 12, and through the interaction between the retention attachment 12 and the target tooth 30, a depressor effect on the target tooth 30 is achieved.
[0038] The retention attachment 12 can be fixedly connected to the target tooth 30 by means of bonding, thereby improving the connection strength between the retention attachment 12 and the target tooth 30. This can prevent the retention attachment 12 from falling off the target tooth 30 or moving between the two when the orthodontic component 11 is used due to insufficient connection strength between the retention attachment 12 and the target tooth 30, which would affect the orthodontic effect.
[0039] The orthodontic component 10 can be positioned close to the labial / buccal side or close to the lingual side, depending on the orthodontic needs of the target tooth 30.
[0040] Among them, the support connection end 111 is connected to the support member 40.
[0041] Specifically, the support connection end 111 can be fixed to the support member 40 by bonding, welding, riveting, plugging, or snapping. This allows the support member 40 to serve as a support point, thereby providing support force to the orthodontic member 11.
[0042] See Figures 1 to 2 The anchorage member 40 can be the adjacent tooth 41 of the target tooth 30, that is, the anchorage connection end 111 is connected to the adjacent tooth 41 of the target tooth 30; see Figure 7 The anchorage component 40 can also be an implant 43 installed on the dentition, that is, the anchorage connection end 111 is connected to the implant 43; in this way, the orthodontic component 10 can be fixedly installed on the patient's teeth, regardless of whether the shell appliance 20 is worn.
[0043] See Figure 5 The anchorage component 40 can also be a shell-shaped orthodontic appliance 20, that is, the anchorage connection end 111 is connected to the shell-shaped orthodontic appliance 20.
[0044] See Figure 6 The orthodontic component 10 may further include a connector 13, which connects at least two teeth on the adjacent side of the target tooth 30 as anchorage teeth 42, with the anchorage connection end 111 connected to the connector 13. Thus, by connecting at least two teeth on the adjacent side of the target tooth 30 as anchorage teeth 42 through the connector 13, with one anchorage tooth 42 adjacent to the target tooth 30, and forming an anchorage component 40 through binding or other restraint methods, the strength of the anchorage component 40 can be increased, thereby improving the orthodontic effect on the target tooth 30.
[0045] Preferably, the connector 13 includes at least two connecting portions 131 that are connected one-to-one with the anchor teeth 42. That is, each anchor tooth 42 in the anchor member 40 is connected to a connecting portion 131, which can improve the connection strength between the connector 13 and the anchor member 40.
[0046] The connecting part 131 can be fixed to the support member 40 by bonding, welding, riveting, plugging or snapping.
[0047] The connector 13 can be made of rubber band, steel wire or shape memory alloy wire, so as to connect or bind at least two anchor teeth 42, thereby improving the anchoring effect of the anchor 14.
[0048] See Figures 1 to 2 as well as Figures 5 to 7 One embodiment of this application also provides a dental system 100, which includes a shell-shaped orthodontic appliance 20 and an orthodontic component 10 as described above. This allows for the combination of the corrective effect of the shell-shaped appliance 20 and the orthodontic effect of the orthodontic component 10, providing flexible treatment options based on the patient's dental condition.
[0049] The shell-shaped orthodontic appliance 20 has a notch 21 on its sidewall corresponding to the target tooth 30 to avoid interference with the free end 112. In this way, the free end 112 can directly act on the target tooth 30 through the notch 21, and interference between the shell-shaped orthodontic appliance 20 and the free end 112 is avoided.
[0050] The shell-shaped aligner 20 can specifically be a transparent component formed from polymer material through a hot-press molding process, also known as an invisible aligner. It forms a cavity to accommodate teeth, wherein the cavity is formed by multiple interconnected tooth-accommodating cavities, that is, the shell-shaped aligner 20 has multiple tooth-accommodating cavities. The cavity has a geometry that repositions the patient's teeth from a first layout to a second layout. The geometry of the cavity is determined based on the second layout of the patient's teeth and substantially matches the second layout of the patient's teeth.
[0051] When the shell-shaped orthodontic appliance 20 is worn on the dentition, the shell-shaped orthodontic appliance 20 covers the outside of the dentition and the dentition can be seen through the shell-shaped orthodontic appliance 20, and the teeth in the dentition are respectively housed in their respective tooth-accepting cavities.
[0052] In the mesiodistal direction, the length of the notch 21 is less than the length of the tooth cavity corresponding to the target tooth 30. This avoids the notch 21 being too large and affecting the strength of the shell-shaped orthodontic appliance 20.
[0053] When the first and second positions are spaced apart in the lingual-buccal direction, the free end 112 of the orthodontic member 11 is located within the tooth cavity in its free state. Thus, when the orthodontic member 11 is in use, the free end 112 tends to move into the tooth cavity in the lingual-buccal direction.
[0054] See Figure 5 In one embodiment, the anchorage connection end 111 is fixed to the shell-shaped orthodontic appliance 20, that is, the shell-shaped orthodontic appliance 20 serves as the anchorage component 40, thereby simplifying the structure of the entire dental system 100.
[0055] See Figures 1 to 2 In another embodiment, the anchorage connection end 111 is connected to the adjacent tooth 41 of the target tooth 30, that is, the adjacent tooth 41 of the target tooth 30 is used as the anchorage element 40. Moreover, the side wall of the shell-shaped orthodontic appliance 20 is provided with a notch 21 corresponding to the adjacent tooth 41 to avoid interference between the anchorage connection end 111 and the shell-shaped orthodontic appliance 20.
[0056] See Figure 6In another embodiment, when at least two teeth on the adjacent side of the target tooth 30 are used as anchorage teeth 42 and the anchorage teeth 42 are connected together by connectors 13, the sidewall of the shell-shaped orthodontic appliance 20 is provided with notches 21 to avoid the connection portions 131 at each connection portion 131, thus avoiding interference between the connection portions 131 and the shell-shaped orthodontic appliance 20.
[0057] In addition, the number of target teeth 30 can be one, two or more.
[0058] Thus, this application has at least the following beneficial effects compared to related technologies: when the orthodontic component 11 is in use, the free end 112 acts on the target tooth 30, and the free end 112 of the orthodontic component 11 has a tendency to move from the second position to the first position. When blocked by the target tooth 30, under the action of its own repositioning force, the orthodontic component 11 applies a force to the target tooth 30 in the lingual-buccal direction, and / or, the orthodontic component 11 applies a force to the target tooth 30 in the occlusal direction, thereby achieving the orthodontic effect on the target tooth 30.
[0059] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0060] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this application, and are not intended to limit the scope of protection of this application. All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this application.
