Description

Technical Field

[0001] The present invention relates to brackets for orthodontics, and particularly to a bracket with a universal groove. Background Art

[0002] The bracket for treating dento-maxillofacial deformities is an important component in the orthodontic treatment of patients with dento-maxillofacial deformities. In the traditional ligation method, the friction between the arch wire and the bracket is relatively large, which will affect the movement of teeth. To improve the above situation, self-locking brackets have emerged on the market. To a certain extent, the self-locking brackets reduce the friction between the arch wire and the bracket, and at the same time reduce the chairside operation time of dentists.

[0003] However, for the existing common self-locking brackets, first, the base body is fixed and even prone to loosening after locking; second, after the axial inclination of the base body is set, the entire bracket cannot be changed after being bonded to the tooth surface. If clinical replacement is needed, it can only be replaced by removing the bracket. For this universal groove bracket, dentists can adjust the clinical axial inclination data according to the actual case to meet the personalized needs of customers.

[0004] Furthermore, in the early stage of tooth alignment, the bracket can achieve the process of self-applying force to the orthodontic arch wire through the rotation feature of the base body, so as to complete the process of orthodontic tooth alignment. Summary of the Invention

[0005] Aiming at the problems existing in the background art, the present invention provides a universal groove bracket, which can flexibly change the direction of the arch wire groove on the bracket body. Clinically, the direction of the arch wire groove can be adjusted without removing the arch wire, so as to meet the correction requirements at different angles.

[0006] The technical solution of the present invention is as follows: A universal groove bracket includes a base plate and a bracket base body with an arch wire groove. A base body base protruding from the base plate is provided on the base plate, and the bracket base body is arranged on the base body base. The bracket base body rotates on the plane of the base body base with the central axis of the base body base as the rotation axis. A plurality of limiting grooves are provided on the side of the base body base, corresponding limiting holes are provided on the base body, and limiting pins are arranged in the limiting holes. After the limiting pins are matched with the limiting grooves, they are used for limiting the rotation position of the bracket base body on the base body base.

[0007] For the universal groove bracket of the present invention, the range of rotation of the bracket base body on the plane of the base body base with the central axis of the base body base as the rotation axis is from +270 degrees to -270 degrees.

[0008] For the universal groove bracket of the present invention, the range of rotation of the bracket base body on the plane of the base body base with the central axis of the base body base as the rotation axis is from +120 degrees to -120 degrees.

[0024] The present invention will be further described below in conjunction with specific embodiments. However, the present invention is not limited to the following embodiments.

[0025] As Figure 1 and Figure 2 shown, a universal groove bracket includes a base plate 1 and a bracket body 2 with an arch wire groove A. A self-locking lock piece 4 can also be provided on the bracket body 2, and the self-locking form of the self-locking lock piece 4 is not limited to this embodiment. As Figure 3 shown, a roller hole 24 is provided on the working wing at the gingival end of the bracket body. As Figure 4 shown, a roller 25 is provided in the roller hole 24. Correspondingly, as Figure 7 shown, a locking blind hole 41 that cooperates with the roller 25 is provided on the lock piece 4. As Figure 3 shown, a chute 26 for setting the lock piece is also provided on the working wing at the gingival end of the bracket body, and slideways 27 and 28 are provided on both sides of the chute 26. The lock piece 4 slides into the chute 26, and at the same time the roller 25 is embedded in the locking blind hole 41. The lock piece 4 slides in the chute 26 to realize the locking and opening of the lock piece.

[0026] As Figure 5 shown, a matrix base 11 protruding from the base plate 1 is provided on the base plate 1. A spring slot 111 and a rotary shaft hole 112 are provided on the matrix base 11, and two limiting springs 113 are also provided in the spring slot 111. As Figure 4 shown, a rotary shaft 22 and a clamping block 21 are respectively provided on the lower surface of the corresponding bracket body 2, and a through hole communicating with the roller hole 24 on the bracket body is provided on the clamping block 21. Two rollers 25 provided in the roller hole 24 are partially located in the through hole. The specific matching method between the bracket body 2 and the matrix base is as follows: the rotary shaft 22 is matched with the rotary hole 112, and the clamping block 21 is embedded in the spring slot 111. The above matching method between the bracket body 2 and the matrix base 11 enables the bracket body 2 to rotate within a range of +270 degrees to -270 degrees with the central axis of the matrix base as the rotation axis.

[0027] As Figure 5 shown, a plurality of limiting slots 114 corresponding to a rotation range of +120 to -120 degrees are provided on the side of the matrix base 11. As Figure 3 shown, a limiting hole 23 is provided on the working wing at the occlusal end of the corresponding bracket body 2. As Figure 1As shown in the figure, a limit pin 3 can be arranged in the limit hole 23. After the limit pin 3 is engaged with the limit groove 114, it is used to limit the rotation position of the bracket matrix 2 on the matrix base 11. A scale is also arranged on the upper surface of the base plate 1 pointed by the limit groove 114 of the matrix base 11, which is used to mark the rotation angle of the bracket matrix 2. As Figure 6 shown, the limit pin 3 is in an "n" shape. One end of the limit pin 3 is inserted into the limit hole 23, and a stepped positioning pin 31 is arranged on the end inserted into the limit hole 23. This positioning pin end can be positioned in any one of the limit grooves 114. The other end of the limit pin 3 is exposed on one side of the bracket matrix 2, and a buckle 32 is arranged on the exposed end. This buckle can be clamped at the lower edge of the bracket matrix. And the end of the end where the buckle 32 is located also has a pointer 33, which is used to point to the scale on the base plate. The two cooperate to mark the rotation angle of the matrix.

[0028] In the application of specific cases, first bond and fix the bracket to the tooth surface through the base plate, and then press the orthodontic arch wire into the slot groove of the bracket. As Figure 8 shown, due to the traction force of the arch wire, the matrix can rotate along the direction shown in the figure, and the rotation angle can be manually adjusted according to clinical needs. Finally, just install the thimble into the matrix and fix it.
