Description

Technical Field

[0001] This utility model relates to the field of orthodontics, specifically to an active self-ligating bracket for orthodontic treatment. Background Technology

[0002] In orthodontic treatment, orthodontic brackets are typically attached to the tooth surface, and the orthodontic archwire is placed within the archwire slots of the brackets to transmit corrective forces and achieve the desired tooth movement. Traditional orthodontic brackets require ligatures or rubber bands to secure the archwire within the bracket. This ligation method is cumbersome and puts significant pressure on the archwire, affecting its normal movement and thus impacting the orthodontic outcome. To address this issue, self-ligating bracket designs have emerged in recent years.

[0003] For example, the Chinese utility model patent publication number CN201453387U, entitled "Active Self-Ligating Bracket for Orthodontics," discloses a self-ligating bracket with a U-shaped locking plate. This bracket has a limiting piece 72 perpendicular to the sliding plate 71 at its end. While the limiting piece 72 can limit the sliding plate 7 and prevent it from detaching from the bracket, its design adds more unevenness to the bracket body, increasing the space for food residue. Furthermore, due to the position and structure of the limiting piece, it is prone to deformation after long-term use, compromising the limiting effect. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an active self-ligating bracket for orthodontics that can effectively limit the sliding locking piece while maintaining a smoother and more even structure of the bracket body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An active self-ligating bracket for orthodontics includes a base plate, a bracket body, and a sliding locking plate. The bracket body has an archwire groove for accommodating an orthodontic archwire, which divides the bracket body into a first working wing and a second working wing. The sliding locking plate includes a sliding plate and a positioning plate, which are connected by an arc-shaped connecting plate. A locking groove is provided on the first working wing, and the end of the positioning plate is positioned within the locking groove. A sliding groove is provided between the bottom of the archwire groove and the base plate, and the sliding plate slides within the sliding groove. At least one protrusion perpendicular to the plane of the sliding plate is provided on the sliding plate, and a limiting groove for the protrusion to slide is provided at a position corresponding to the protrusion within the sliding groove.

[0007] The aforementioned active self-ligating bracket for orthodontic use has two convex strips that are parallel to each other on the upper surface of the slide plate along the sliding direction. The limiting grooves are also parallel to each other on the top surface of the slide groove, and each limiting groove has a stop at its end.

[0008] The aforementioned active self-ligating bracket for orthodontic use has two raised strips, which are spaced apart at the ends of the upper surface of the slide plate along the vertical sliding direction. The limiting groove is a recessed groove on the top surface of the slide plate, and the raised strips slide within the recessed groove.

[0009] The aforementioned active self-ligating orthodontic bracket features a raised rib parallel to the end of the slide plate, and a recessed groove on the top surface of the slide plate, within which the raised rib slides. Alternatively, the raised rib can be configured as a retaining groove, with a retaining strip engaging with the retaining groove at the end of the recess furthest from the archwire groove.

[0010] The aforementioned active self-ligating orthodontic bracket has a locking hole on its positioning plate.

[0011] The aforementioned active self-ligating orthodontic bracket has a guide groove on the first working wing opposite the unlocking hole, and an alignment line is provided at the center of the bottom surface of the guide groove.

[0012] In summary, the advantages of this utility model are as follows:

[0013] Because the protrusions on the slide plate are limited by the limiting grooves inside the bracket body, the sliding locking piece can be guaranteed not to detach from the bracket body. Furthermore, since both the limiting grooves and protrusions are hidden inside the bracket body, the smoothness and flatness of the bracket body's perimeter are ensured, reducing the space for food residue residue during clinical use.

[0014] Furthermore, the cooperation between the convex strip and the limiting groove allows the sliding locking piece to slide stably and with guidance within the groove, enabling the sliding locking piece to lock the bow wire more stably and accurately. Attached Figure Description

[0033] Example 1:

[0034] like Figure 1 As shown, the active self-ligating bracket for orthodontic treatment includes a base plate 1, a bracket body 3, and a sliding locking plate 2. The bracket body 3 has an archwire groove 4 for accommodating the orthodontic archwire. The archwire groove 4 divides the bracket body 3 into a first working wing 31 and a second working wing 32. The first working wing 31 can be a separate working wing or a single working wing. The second working wing 32 is divided into two separate working wings by the sliding locking plate 2.

[0035] like Figure 2 As shown, the sliding locking piece 2 includes a sliding plate 23 and a positioning plate 21, which are connected by an arc-shaped connecting plate 22. Figure 1 As shown, a locking groove 34 is provided on the first working wing 31, and the end of the positioning plate 21 is positioned within the locking groove 34. In a specific implementation, the locking groove 34 is provided on one of the sidewalls of the bowwire groove located on the first working wing, and it can be a complete locking groove or two separate locking grooves located at opposite ends of the sidewall. Correspondingly, as... Figure 2 As shown, the end of the positioning plate 21 can be a single, complete side, or two protruding ends that correspond one-to-one with the separate locking grooves. Furthermore, to better lock the end of the positioning plate 21 within the locking groove, a locking edge 24 can be provided at the end of the positioning plate 21.

[0036] like Figures 3 to 7 As shown, a sliding groove 33 is provided between the bottom 4 of the bow wire groove and the base plate 1 for the sliding locking piece 2 to slide. Specifically, the sliding plate 23 of the sliding locking piece 2 slides within the sliding groove 33. Two protrusions 231 perpendicular to the plane of the sliding plate are provided on the sliding plate 23. Two limiting grooves 331, each for sliding the two protrusions 231, are provided at positions corresponding to the sliding groove 33 and the protrusions 231. The two protrusions 231 are arranged side-by-side at intervals along the sliding direction of the sliding plate 23, and the two corresponding limiting grooves 331 are arranged parallel to each other on the top surface of the sliding groove. Each limiting groove 331 has a stop 332 at its end. The stop 332 prevents the sliding locking piece 2 from detaching from the bracket body 3.

[0037] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the positioning plate 21 of the sliding lock plate 2 is also provided with an unlocking hole 25, which makes it convenient for tools to open the sliding lock plate 2.

[0038] like Figure 1 , Figure 3 and Figure 6 As shown, a guide groove 35 is also provided on the first working wing 31 opposite to the unlocking hole 25, and an alignment line 36 is also provided at the center of the bottom surface of the guide groove 35. The guide groove 35 serves as a guide for unlocking, and the alignment line 36 serves as a center line.

[0039] In this embodiment of the active self-ligating orthodontic bracket, during assembly, the sliding locking piece 2 is first positioned within the sliding groove 33, and then the base plate 1 is sealed. The protrusions and limiting grooves ensure that the sliding locking piece does not detach from the bracket body, and also ensure that no excess structure protrudes from the bracket body when the sliding locking piece is in the locked position, thus ensuring a smooth and flat surface without any excess space for food residue.

[0040] Example 2:

[0041] like Figure 8 As shown, the other structures in this embodiment are the same as in Embodiment 1. The difference lies in that the protrusions on the sliding plate 2 are two parallel protrusions 232 arranged along the parallel sliding direction of the sliding plate. The structures of the limiting groove and the stop block remain unchanged, only the size of the limiting groove is adaptively changed according to the size of the protrusions 232. The protrusions 232 arranged in this way have both a limiting function and an effect of increasing the smoothness of the sliding plate.

[0042] Example 3:

[0043] like Figures 9 to 11 As shown, the other structures of this embodiment are the same as those of Embodiment 1. The difference lies in that the protrusion on the sliding plate of the sliding lock piece 2 is a single protrusion 230 located at the end of the sliding plate and parallel to the end of the sliding plate, and the limiting groove is a recessed groove 330 located on the top surface of the sliding groove, and the protrusion 230 slides within the recessed groove 330. Figure 10 He Ru Figure 11 As shown, the first side 333 and the second side 334 of the recess 330 act as retaining edges to ensure that the sliding locking piece 2 will not detach from the bracket body, so that the protrusion 230 can only slide within the recess 330.

[0044] Example 4

[0045] like Figure 12 and Figure 13As shown, the other structures in this embodiment are the same as in Embodiment 3. The difference lies in that the protrusion on the sliding plate 2 is a single protrusion located at the end of the sliding plate and parallel to the end of the sliding plate, and the protrusion is configured as a U-shaped groove 230a. The limiting groove is a recessed groove 330 located on the top surface of the sliding groove, and the groove 230a slides within the recessed groove 330. Furthermore, a retaining strip 230b is provided on one side wall of the recessed groove 330 opposite to the groove. When the sliding plate is slid open to the fully open state under the action of a tool, the retaining strip 230b engages with the U-shaped groove 230a, thereby ensuring that the sliding plate 2 is stably fixed on the bracket body.

[0046] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
