[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] Reference Figure 1 To Attachment Figure 6 As shown, the present application discloses an axial tilt control attachment, comprising:

[0044] The bonding seat 1 comprises a bonding portion 11 for connecting with the tooth surface and a positioning structure 12 fixed on the bonding portion 11;

[0045] The transmission member 2 is covered on the bonding seat 1, one side of the transmission member 2 is an adapting structure 21 that cooperates with the positioning structure 12, and the other side is a transmission surface that cooperates with the invisible orthodontic appliance;

[0046] The elastic member 3 is arranged between the positioning structure 12 and the adapting structure 21 .

[0047] In the present application, the bonding seat 1 and the transmission member 2 can be rotatably connected to each other and constrained by the elastic member 3, thereby allowing the two to be fine-tuned. Functionally, the axial tilt control attachment can achieve precise control of the movement of the teeth in the axial tilt direction. At the same time, through the flexible assembly between the transmission member 2 and the bonding seat 1, the relative position of the invisible attachment can be adjusted, and there is no need to remove the invisible attachment during the correction process. Overall, it can effectively reduce the bedside operation time and frequency while ensuring the correction effect, improve the treatment experience of clinicians and patients, and has a high promotion value.

[0048] The assembly form of the bonding seat 1 and the transmission member 2 can be screwed, clamped, etc., and can also refer to an embodiment, the positioning structure 12 includes:

[0049] A protrusion 121 extending from the adhesive portion 11 away from the tooth surface;

[0050] The constraint hole 122 extends parallel to the bonding plane of the bonding portion 11 . The elastic member 3 is rod-shaped and includes a constraint section 31 received in the constraint hole 122 and a working section 32 protruding out of the constraint hole 122 . The transmission member 2 cooperates with the working section 32 .

[0051] To match it, the shape of the positioning structure 12 should be complementary to the adapting structure 21. It can also be referred to an embodiment in which the cross-sectional shape of the transmission member 2 is semicircular and the semicircular arc surface is the transmission surface, and the adapting structure 21 is arranged inside the transmission member 2 and includes

[0052] A first hole 211 is provided on the bottom surface of the transmission member 2, and the first hole 211 is used to receive the bonding portion 11;

[0053] The second hole 212 is connected to the first hole 211 and is smaller than the first hole 211. The second hole 212 is used to accommodate the positioning structure 12;

[0054] The adapting groove 213 is formed on the side wall of the first hole 211 and / or the second hole 212 , and is used to receive the working section 32 .

[0055] It is not difficult to understand from the above that the shapes of the two are complementary and interlocked, thereby providing a relatively closed space for the installation of the elastic member 3, and the assembly of the two is mainly achieved by the mutual engagement between the positioning structure 12 and the adapting structure 21. Referring to an embodiment, a positioning ring 123 is provided on the top of the protrusion 121, and the adapting structure 21 includes a positioning groove 214 for clamping the positioning ring 123. The two are mutually engaged through elastic deformation to achieve the positioning of the bonding seat 1 and the transmission member 2 in the axial direction of the protrusion 121.

[0056] The adapting groove 213 can restrain the elastic member 3 and bear the elastic force of the elastic member 3 at the same time, thereby realizing the torque transmission between the bonding seat 1 and the elastic member 3. In the accompanying drawings, the adapting groove 213 is opened at two places, and is respectively matched with the two ends of the elastic member 3. Each adapting groove 213 is distributed on the side edges of the first hole 211 and the second hole 212, and the notch of the adapting groove 213 located on the side edge of the first hole 211 is larger than the notch located on the side edge of the second hole 212. In terms of the setting details of the adapting groove 213, referring to an embodiment, the adapting groove 213 is open to the bottom surface of the transmission member 2, and the bottom surface of the transmission member 2 is flush with the bottom surface of the bonding portion 11. The adapting groove 213 and the bottom surface of the transmission member 2 are transitioned through a bell mouth to facilitate the elastic member 3 to enter the adapting groove 213.

[0057] The assembly of the elastic member 3 is realized by the constraint hole 122. Referring to an embodiment, the constraint hole 122 is arranged close to the top surface of the bonding portion 11. In the matching relationship between the elastic member 3 and the bonding seat 1, referring to an embodiment, the bonding portion 11 is cylindrical, and the axial length of the elastic member 3 is greater than the diameter of the bonding portion 11. The above arrangement can better realize the mechanical transmission of the elastic member 3 between the transmission member 2 and the bonding seat 1.

[0058] From the outside, the matching relationship between the adhesive seat 1 and the transmission member 2 is shown in one embodiment, where the adhesive seat 1 is accommodated inside the transmission member 2. Or, in the embodiment shown in the accompanying drawings, at least a portion of the adhesive seat 1 is exposed to the side wall of the transmission member 2. In other words, in the accompanying drawings, the dimension of the transmission member 2 in the non-axial direction of the elastic member 3 is smaller than the diameter of the adhesive portion 11, thereby releasing a portion of the adhesive portion 11 to the outside of the transmission member 2. This arrangement can reduce the overall volume of the transmission member 2 and reduce the foreign body sensation.

[0059] From another perspective, the transmission surface of the transmission member 2 includes at least any one of the following:

[0060] The first transmission surface 215 is parallel to the bonding surface of the bonding portion 11;

[0061] The second transmission surface 216 is perpendicular to the first transmission surface 215 and parallel to the extension direction of the constraint hole 122;

[0062] The third transmission surface 217 is perpendicular to the first transmission surface 215 and the second transmission surface 216 .

[0063] In the embodiment shown in the accompanying drawings, the transmission member 2 includes a first transmission surface 215, a second transmission surface 216 and a third transmission surface 217. In this embodiment, the first transmission surface 215 is not completely parallel to the bonding surface, but a part of it has the same extension trend as the bonding surface. In detail, the first transmission surface 215 is an arc surface, a part of which is parallel to the bonding surface of the bonding portion 11; the second transmission surface 216 is provided with two parallel arrangements, and the third transmission surface 217 is also provided with two parallel arrangements and intersects with the first transmission surface 215. In the actual setting, the above-mentioned transmission surfaces have a variety of deformations. The core idea is that the transmission member 2 can transmit torques in multiple directions. Under the guidance of this idea, the outer surface shape of the transmission member 2 can be flexibly set. The setting method in this embodiment is the preferred method that takes into account both the transmission effect and the overall volume.

[0064] Combined with the above, it is not difficult to understand. Figure 1 To Attachment Figure 7 As shown, the present application also discloses an invisible braces, including an invisible braces body 4 and an axial tilt control accessory 41 in the above technical solution, wherein the invisible braces body 4 is covered on the transmission member 2 and is force-matched with the transmission member 2.

[0065] The correction data of the invisible braces body 4 is transmitted to the elastic member 3 that is squeezed by the adapter groove 213 through the mechanical action with the transmission member 2, and then transmitted to the constraint hole 122 and the bonding seat 1 through the elastic member 3, so as to be displayed on the teeth. This process can ensure the accurate expression of the correction data. During the correction process, the elastic member 3 can continuously output a stable correction torque through its own elastic force, thereby improving the correction effect. On the other hand, when necessary, the doctor can correct and adjust the expression of the correction data by adjusting the transmission member 2 or replacing the transmission member 2 without replacing the new bonding seat 1, thereby effectively improving the operating efficiency. Improve the treatment experience of doctors and patients.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0067] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
