Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically to a lightweight self-locking bracket. Background Technology

[0002] Orthodontic treatment is a highly specialized branch of dentistry. Orthodontic brackets are devices made of metal or ceramic materials, fixed to the tooth surface with a special adhesive, used in orthodontic treatment to house and fix orthodontic wires, transmitting corrective force to the teeth to achieve the goal of orthodontic correction. In existing technology, the archwire groove on the bracket has a rectangular structure with right angles on both sides. During use, unevenness of the teeth can cause the archwire to bend, causing the bent portion of the archwire to directly contact the right angles on both sides of the archwire groove. This increases the frictional resistance between the archwire and the archwire groove, reducing its lifespan. Therefore, a lightweight self-ligating bracket is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight self-locking bracket to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lightweight self-ligating bracket, comprising a bracket body and a main archwire groove disposed on the bracket body; the main archwire groove is provided with a occlusal sidewall and a gingival sidewall; characterized in that a self-ligating cover plate and a locking element for locking the self-ligating cover plate are slidably mounted on the bracket body; the occlusal sidewall and the gingival sidewall are both provided with a gradually rounded flared opening that allows the archwire more free bending and deformation space in the main archwire groove.

[0005] Preferably, the gradually enlarging arc-shaped flared opening extends progressively towards the mesial and distal ends on the jaw and gingival walls of the groove.

[0006] Preferably, the gradually rounded flared openings on the jaw and gingival sides of the groove are symmetrically arranged along the central axis of the bracket.

[0007] Preferably, the automatic cover plate is provided with a through-hole groove that works in conjunction with a locking element to lock the automatic cover plate.

[0008] Preferably, the diameters at both ends of the through-hole groove are larger than those in the middle section to match the locking element.

[0009] Preferably, the locking element is an integral structure, with one end passing through the bracket and the self-locking cover plate and fixed on the bracket.

[0010] Preferably, the locking element is a split structure, with one end inserted into the through hole groove from both sides of the bracket body into the self-locking cover plate.

[0011] Preferably, the device also includes a sliding groove on the bracket body for guiding the self-locking cover, a locking groove communicating with the sliding groove for locking the locking element, and a sliding limiting groove on the bracket body for limiting the sliding movement of the self-locking cover.

[0012] The beneficial effects of this utility model are as follows: by setting a gradually rounded flared opening on the occlusal side wall and gingival side wall of the main archwire groove, the space for the archwire to bend or deform freely in the main archwire groove is increased, the friction between the archwire and the main archwire groove is reduced, and thus the alignment and leveling efficiency is improved. By using locking devices to lock the self-locking cover plate that is slidably mounted on the bracket body and hidden under the self-locking cover plate, oral hygiene can be easily ensured, while improving the stability and reliability of the self-locking cover plate.

[0018] The following description, in conjunction with the accompanying drawings, further illustrates the lightweight self-locking bracket of this utility model.

[0019] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0020] In one embodiment, see Appendix Figure 1-4As shown, this embodiment of a lightweight self-ligating bracket includes a bracket body 1 and a main archwire groove 101 disposed on the bracket body 1; the main archwire groove 101 is provided with a groove occlusal sidewall 102 and a groove gingival sidewall 103; characterized in that a self-ligating cover plate 2 and a locking member 3 hidden under the automatic cover plate and locking the automatic cover plate are slidably installed on the bracket body 1; both the groove occlusal sidewall 102 and the groove gingival sidewall 103 are provided with a gradually rounded flared opening 104 to allow the archwire more free bending and deformation space in the main archwire groove 101; the gradually rounded flared opening 104 gradually extends and enlarges towards the mesial and distal ends on the groove occlusal sidewall 102 and the groove gingival sidewall 103; the gradually rounded flared opening 104 on the groove occlusal sidewall 102 and the groove gingival sidewall 103 are symmetrically arranged along the central axis of the bracket body 1. By setting a gradually rounded flared opening 104 on the occlusal sidewall 102 and gingival sidewall 103 of the main archwire groove 101, the space for the archwire to bend or deform freely in the main archwire groove 101 is increased, the frictional resistance between the archwire and the main archwire groove 101 is reduced, thereby improving the alignment and leveling efficiency, while not affecting the torque control of the square archwire in the later stage. By using the locking element 3 to lock the self-locking cover 2 that is slidably mounted on the bracket body 1 and hidden under the self-locking cover 2, oral hygiene can be easily ensured, while improving the stability and reliability of the automatic cover.

[0021] See appendix Figure 2-3 As shown, the self-locking cover plate 2 is provided with a through-hole groove 201 that works in conjunction with the locking member 3 to lock the self-locking cover plate 2; the diameter of the two ends of the through-hole groove 201 is larger than that of the middle section and is adapted to the locking member 3; the locking member 3 is an integral structure, with one end penetrating through the support body 1 and the self-locking cover plate 2 and fixed on the support body; the through-hole groove 201 on the self-locking cover plate 2 is a through structure; by having one end of the locking member 3 penetrate through the support body 1 and the self-locking cover plate 2, the two ends of the locking member 3 are respectively installed at the two ends of the support body 1. When the self-locking cover plate 2 slides, the through-hole groove 201 slides along the locking member 3. When the locking member 3 is at both ends of the through-hole groove 201, the locking member 3 locks the self-locking cover plate 2, which requires a large force. When the locking member 3 is in the middle section of the through-hole groove 201, the locking member 3 is squeezed, thereby improving the stability of the sliding of the self-locking cover plate 2.

[0022] In one embodiment, the locking member 3 is a split structure. One end of the split locking member 3 is inserted into the through-hole groove 201 from both sides of the bracket body 1 and installed into the self-locking cover plate 2. The through-hole groove 201 on the self-locking cover plate 2 is a non-through structure. By inserting one end of the two split locking members 3 from both sides of the bracket body 1 into the through-hole groove 201 on the self-locking cover plate 2, and the other end is installed on the bracket body 1, when the self-locking cover plate 2 slides, the through-hole groove 201 slides along the locking member 3. When the locking member 3 is at both ends of the through-hole groove 201, the locking member 3 locks the self-locking cover plate 2. A large force needs to be applied so that when the locking member 3 is in the middle section of the through-hole groove 201, the locking member 3 is squeezed, thereby improving the stability of the sliding of the self-locking cover plate 2.

[0023] In one embodiment, see Appendix Figure 3-4 As shown, it also includes a sliding groove 105 on the bracket body 1 for sliding guidance of the self-locking cover plate 2, a locking groove 106 communicating with the sliding groove 105 for locking the locking member 3, and a sliding limiting groove 107 on the bracket body 1 for sliding limitation of the self-locking cover plate 2; when the self-locking cover plate 2 slides along the sliding groove 105 on the bracket body 1, the sliding groove 105 compresses the two ends of the locking member 3 and slides with the self-locking cover plate 2 until the two ends of the locking member 3 slide to the locking groove 106, the locking member 3 resets and locks into the locking groove 106 by its own elasticity, thereby locking the self-locking cover plate 2; when the self-locking cover plate 2 slides outward, when the locking member 3 contacts the sliding limiting groove 107, the sliding limiting groove 107 limits the locking member 3, thereby limiting the self-locking cover plate 2 and preventing the self-locking cover plate 2 from sliding out of the bracket body 1.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
