Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic appliance. Background Technology
[0002] Current orthodontic appliances achieve retention by encasing the tooth crowns. However, in the process of invisible orthodontic treatment, various attachments are often designed into the appliances to achieve the desired effect. When adding attachments to the appliances, a certain area is required. This area is generally the buccal, lingual, or occlusal surface. Most attachments are added to the buccal and lingual surfaces. In this case, the area that can be added is generally limited by the area formed by the edge of the appliance and the incisal edge of the occlusal surface, which may lead to failure to achieve the desired treatment effect. Furthermore, the use of attachments will be affected by the angle of the added area. Utility Model Content
[0003] One of the objectives of this invention is to provide an orthodontic device that can improve the stability of accessories during use.
[0004] This utility model provides an orthodontic appliance, including an appliance body and an accessory disposed on the appliance body. The appliance body includes a mounting base for adding the accessory. When the appliance is fitted onto the dentition, the mounting base is close to the first gingival line of the dentition, or the mounting base intersects the first gingival line in a direction perpendicular to the occlusal plane. The mounting base includes a first end and a second end disposed opposite to each other. The first end has a first distance from the dentition, and the second end has a second distance from the dentition, wherein the first distance is greater than the second distance.
[0005] Optionally, the mounting base may be partially located below the first gingival line of the dental tissue and partially located above the first gingival line of the dental tissue; or, the mounting base may be entirely located below the first gingival line, or the mounting base may be entirely located above the first gingival line.
[0006] Optionally, the dental tissue includes a crown located above the first gingival line and a gingiva located below the first gingival line, a first end corresponding to the crown, and a first distance between the first end and the crown, a second end corresponding to the gingiva, and a second distance between the second end and the gingiva.
[0007] Optionally, the second end is placed close to the gum.
[0008] Optionally, the orthodontic appliance body further includes a first region and a connecting region connecting the first region and the mounting base, the first region being in close contact with the dentition, and the connecting region forming a bend between the first region and the mounting base.
[0009] Optionally, the mounting base is planar.
[0010] Optionally, the angle between the plane of the mounting base and the jaw plane is in the range of 60°-90°.
[0011] Optionally, the bottom surface of the accessory is connected to the mounting base, and the bottom surface covers part or all of the area of the mounting base.
[0012] Optionally, the accessory may be a tow hook, a tow chain, a tubular accessory, or a grooved accessory.
[0013] Optionally, the mounting base extends below the first gingival line, and the orthodontic appliance includes an appliance edge cutting line. The preset distance between the appliance edge cutting line and the corresponding outer contour line of the mounting base ranges from 0.2 mm to 2 mm.
[0014] Optionally, the mounting base extends below the first gingival line, and the orthodontic appliance includes an appliance edge cutting line, which is located below the first gingival line only in a portion of the mounting base, while the remaining portion of the appliance edge cutting line substantially coincides with the first gingival line.
[0015] Optionally, the mounting base portion extends below the first gingival line, and the orthodontic appliance includes an appliance edge cutting line, the appliance edge cutting line being located below the first gingival line in the portion of the mounting base and other portions adjacent to the mounting base.
[0016] Optionally, when the orthodontic appliance is fitted onto the jawbone and occludes with the opposing teeth, the attachment is spaced apart from the opposing teeth.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the mounting base of this utility model is generally biased towards an upright state. For example, when it is used as an accessory for traction buckle or traction hook, compared with mounting the accessory on a mounting base that is biased towards a horizontal state, the accessory mounted on a mounting base that is biased towards an upright state is more conducive to the sleeve of the traction component (e.g., rubber band), avoids the traction component from easily detaching from the accessory, and is conducive to the stable application of force by the traction component.

[0022] 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.
[0023] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.
[0024] This utility model embodiment provides an orthodontic appliance 10, combined with... Figures 1 to 3 The orthodontic appliance 10 includes an appliance body 101 and an accessory 50 disposed on the appliance body 101. The appliance body 101 includes a mounting base 70 for adding the accessory 50. When the orthodontic appliance 10 is fitted onto the dentition T, the mounting base 70 is close to the first gingival line 30 of the dentition T, or the mounting base 70 intersects with the first gingival line 30.
[0025] The dental tissue T includes teeth and gingiva. Teeth include the connected crown and root. The gingiva surrounds the root. The dental tissue T is divided by the first gingival line 30. Above the first gingival line 30 is the direction of the crown 20 of the dental tissue T, and below the first gingival line 30 is the direction of the gingiva T1 of the dental tissue T.
[0026] "The mounting abutment 70 is close to the first gingival line 30 of the dental tissue" means that the mounting abutment 70 is in the vicinity of the first gingival line 30. "The mounting abutment 70 intersects with the first gingival line 30" means that the first gingival line 30 passes through the mounting abutment 70. In short, the mounting abutment 70 is in a region far away from the incisal edge (or occlusal surface) of the tooth.
[0027] Optionally, the mounting abutment 70 may be partially located below the first gingival line 30 of the dental tissue T and partially located above the first gingival line 30 of the dental tissue T; or, the mounting abutment 70 may be entirely located below the first gingival line 30, or the mounting abutment 70 may be entirely located above the first gingival line 30. That is, the mounting abutment 70 may be located on one side of the first gingival line 30, or the mounting abutment 70 may be located on both sides of the first gingival line 30. In this embodiment, the mounting abutment 70 is partially located below the first gingival line 30 of the dental tissue T and partially located above the first gingival line 30 of the dental tissue T. The mounting abutment 70 extends from the crown 20 region above the first gingival line 30 to the gingival T1 region below the first gingival line 30.
[0028] In the existing technology, the edge cutting line 40 of the orthodontic appliance is perfectly matched with the first gingival line 30. When the crown 20 of the dental tissue is low, the area where the attachment 50 can be added will be relatively small in the vertical direction of the tooth, which may not meet the space size requirements for adding the attachment 50, resulting in the attachment 50 not being able to be added or having a low success rate.
[0029] Alternatively, if the added attachment 50 interferes with the occlusal bite of the opposing teeth, it needs to be moved further towards the first gingival line 30. However, due to the limitation of the appliance edge cutting line 40, there is no space required to continue moving, which results in the attachment 50 not being added successfully.
[0030] In this embodiment, the mounting base 70 extends from the crown 20 region above the first gingival line 30 to the gingival T1 region below the first gingival line 30. The mounting base 70 is relatively large, which can provide more space for the installation of the accessory 50.
[0031] In a direction perpendicular to the jaw plane P, the mounting base 70 includes a first end 71 and a second end 72 disposed opposite to each other. The first end 71 has a first distance S1 between itself and the jaw tissue T, and the second end 72 has a second distance S2 between itself and the jaw tissue T. The first distance S1 is greater than the second distance S2.
[0032] "The first gap S1 is greater than the second gap S2" means that the area of the mounting base 70 near the incisal edge (or occlusal surface) of the tooth is further away from the dental tissue T than the area far away from the incisal edge (or occlusal surface). This is equivalent to locally pulling and raising the mounting base 70, which was originally set close to the dental tissue T, so that the mounting base 70 extends roughly along the direction X perpendicular to the occlusal plane P, that is, the mounting base 70 is biased to an upright state.
[0033] Attachment 50 is a traction buckle, traction hook, tubular attachment or groove-shaped attachment. Compared with installing the attachment on the mounting base 70 which is biased to a horizontal position, installing the attachment 50 on the mounting base 70 which is biased to a vertical position is conducive to the sleeve of the traction component (such as a rubber band), prevents the traction component from easily detaching from the attachment 50, and is conducive to the stable application of force by the traction component.
[0034] When the mounting base 70 is partially located below the first gingival line 30 of the dental tissue T and partially located above the first gingival line 30 of the dental tissue T, the first end 71 corresponds to the crown 20, and there is a first distance S1 between the first end 71 and the crown 20. The second end 72 corresponds to the gingiva T1, and there is a second distance S2 between the second end 72 and the gingiva T1.
[0035] Optionally, the mounting base 70 is a plane, and the angle α between the plane of the mounting base 70 and the jaw plane P is in the range of 60°-90°. That is, the plane of the mounting base 70 extends approximately along the direction X perpendicular to the jaw plane P, but is not limited to absolute perpendicularity.
[0036] Optionally, the second end 72 is close to the gingiva T1. The mounting base 70 is only pulled outward and raised in the area of the first end 71 and adjacent to the first end 71. The second end 72 is not pulled outward and raised. The second end 72 is still close to the gingiva T1, which can improve the overall encapsulation performance of the appliance 10 on the dentition and jaw tissue.
[0037] Optionally, the orthodontic appliance body 101 may also include a first region 80 and a connecting region 90 connecting the first region 80 and the mounting base 70. The first region 80 is in close contact with the crown 20, and the connecting region 90 forms a bend between the mounting base 70 and the first region 80.
[0038] "The connecting area 90 forms a bend between the mounting base 70 and the first area 80" means that the connecting area 90 forms a bend between the mounting base 70 and the first area 80, which can realize the outward pulling and raising of the mounting base 70.
[0039] The connecting area 90 extends generally horizontally, the mounting base 70 extends generally vertically, the first area 80 and the connecting area 90 are generally perpendicular to each other, and the connecting area 90 and the mounting base 70 are generally perpendicular to each other, but not limited thereto, the first area 80, the connecting area 90 and the mounting base 70 can also be in other bending forms.
[0040] Combination Figure 4This is a schematic diagram of two attachments 50 connected by a traction member 52. Taking attachment 50 as a traction buckle as an example, attachment 50 includes a bottom 53 connected to the mounting base 70, a connecting rod 54 connected to the bottom 53, and a top 55 located on the side of the connecting rod 54 away from the bottom 53. The traction member 52 is sleeved on the connecting rod 54.
[0041] When the mounting base 70 extends approximately along the direction X perpendicular to the jaw plane P, the extension direction of the connecting rod 54 is approximately perpendicular to the buccal surface of the tooth, while the extension direction of the traction member 52 is approximately parallel to the buccal surface of the tooth. This prevents the traction member 52 from detaching from the connecting rod 54 and ensures stable force application by the traction member 52.
[0042] When the two attachments 50 are not in the same jaw, the mounting base 70, which extends approximately in the direction X perpendicular to the jaw plane P, can be used to prevent the traction member 52 from disengaging from the connecting rod 54 and ensure the stable application of force by the traction member 52.
[0043] It should be noted that the junction between the crown 20 and the gingiva T1 is a relatively steep slope. At this point, the mounting base 70 is more likely to be biased towards a horizontal position. Therefore, the mounting base 70 is pulled outward and raised to effectively avoid affecting the normal use of the accessory 50 due to the angle of the mounting base 70.
[0044] Optionally, the bottom surface 51 of the annex 50 is connected to the mounting base 70, and the bottom surface 51 covers part or all of the area of the mounting base 70.
[0045] When the bottom surface 51 covers a portion of the mounting base 70, the bottom surface 51 may be located in the middle area of the mounting base 70, the lower area of the mounting base 70, or the upper area of the mounting base 70, etc. The projection of the accessory 50 within the mounting base 70 may be within the outer contour of the mounting base 70 or may extend beyond the outer contour of the mounting base 70.
[0046] When the bottom surface 51 covers the entire area of the mounting base 70, the outer contour of the bottom surface 51 coincides with the outer contour of the mounting base 70, and the projection of the attachment 50 within the mounting base 70 can be within the range of the outer contour of the mounting base 70 or exceed the outer contour of the mounting base 70.
[0047] Optionally, a tooth gap is formed between the crowns 20 of two adjacent teeth. When the appliance 10 is fitted onto the jawbone, the mounting abutment 70 is set to correspond to the crown 20 of at least one tooth or the tooth gap.
[0048] When there is one tooth, the mounting abutment 70 corresponds to the crown 20 and gingival T1 of the tooth. When there are multiple teeth, the mounting abutment 70 corresponds to the crown 20, gingival T1, and interdental spaces of multiple teeth.
[0049] Optionally, when the appliance 10 is fitted onto the dentition T, the attachment 50 is at least partially located on at least a portion of the appliance 10 corresponding to at least a portion of the tooth or the interdental space.
[0050] When there is only one tooth, the attachment 50 corresponds to the crown 20 and gingival T1 of the tooth. When there are multiple teeth, the attachment 50 corresponds to the crown 20, gingival T1, and interdental spaces of multiple teeth.
[0051] Optional, combined Figure 1 The mounting abutment 70 extends below the first gingival line 30. The appliance 10 includes an appliance edge cutting line 40, which is located below the first gingival line 30 only in part of the mounting abutment 70. The remaining part of the appliance edge cutting line 40 substantially overlaps with the first gingival line 30.
[0052] Figure 1 Taking the crown 20 and gingival T1 of a tooth corresponding to the mounting abutment 70 as an example, the edge cutting line 40 of the orthodontic appliance only protrudes to the gingival T1 area below the first gingival line 30 at that tooth, while the edge cutting line 40 of the orthodontic appliance coincides with the first gingival line 30 at other teeth.
[0053] Figure 1 The edge cutting line 40 of the orthodontic appliance can also be extended only at the T1 gingival region below the first gingival line 30 at the mounting base 70. The edge cutting line 40 of the orthodontic appliance coincides with the first gingival line 30 in the area of the tooth other than the corresponding mounting base 70 and in other teeth.
[0054] Optional, combined Figure 5 The orthodontic appliance 10 includes an appliance edge cutting line 40, which is located below the first gingival line 30 in the portion of the mounting base 70 and in other portions adjacent to the mounting base 70.
[0055] Figure 5 Taking the crown 20 and gingival T1 of a tooth corresponding to the mounting abutment 70 as an example, the appliance edge cutting line 40 not only protrudes to the gingival T1 area below the first gingival line 30 at the tooth with the mounting abutment 70, but also protrudes to the gingival T1 area below the first gingival line 30 at the left and right teeth adjacent to the tooth. At this time, the appliance edge cutting line 40 protruding to the first gingival line 30 passes through three teeth.
[0056] Optionally, the preset distance L between the edge cutting line 40 of the orthodontic appliance and the edge contour line of the corresponding mounting base 70 is in the range of 0.2 mm to 2 mm.
[0057] The preset distance L is the vertical distance between the edge cutting line 40 of the orthodontic appliance and the edge contour line of the mounting base 70. The preset distance L is controlled by adjusting the preset distance L.
[0058] Optionally, when the orthodontic appliance 10 is fitted onto the jawbone and occludes with the opposing teeth, the attachment 50 is spaced apart from the opposing teeth, meaning that when in occlusion, there is no mutual interference between the attachment 50 and the opposing teeth.
[0059] In summary, when the accessory 50 of this utility model is used as a traction buckle or traction hook, compared with installing the accessory on the mounting base 70 which is biased to a horizontal state, the accessory 50 installed on the mounting base 70 which is biased to a vertical state is more conducive to the sleeve of the traction component (e.g., rubber band), avoids the traction component from easily detaching from the accessory 50, and is conducive to the stable application of force by the traction component.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0061] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model.
