Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic instruments, in particular to a self-locking bracket which is suitable for human body and convenient for torque control. Background Art

[0002] Self-ligating brackets are a special device used in orthodontic treatment. They are fixed to the tooth surface with a special adhesive. They are made of materials such as metal or ceramics and are mainly used to hold and fix orthodontic wires, thereby transmitting correction force to the teeth to achieve the purpose of tooth correction.

[0003] Compared with traditional orthodontic technology, the biggest feature of self-ligating brackets is their innovative design. It adds a locking device that can directly lock the orthodontic wire in the groove of the bracket, without the need to use traditional ligature wires or rubber bands to bind the orthodontic wire. This design greatly reduces the friction resistance between the wire and the bracket, reduces the force on the teeth, speeds up tooth movement, and effectively shortens the entire treatment time.

[0004] Existing self-ligating brackets mainly use latches or other movable sliders to fix the archwire in the bracket, without the need for ligation, which reduces the friction resistance between the archwire and the bracket and shortens the correction period. However, existing self-ligating brackets have the risk of bracket cover failure and falling off, and the structure is relatively complex, which makes the correction operation more cumbersome and difficult. In addition, due to its complex surface structure, food residues are often stuck inside, which affects the appearance and is not easy to clean. In order to solve the above problems, while improving the structure, simplifying its operation and facilitating the cleaning of its surface, we propose a self-ligating bracket based on human body applicability and convenient torque control.
