Description

Technical Field

[0001] The present invention relates to the technical field of orthodontics, and particularly to an open slot main and passive integrated self-locking bracket. This main and passive integrated self-locking bracket is a device for straightening deformed teeth by an arch wire in orthodontics. Background Art

[0002] Common self-locking brackets are divided into: active self-locking brackets and passive self-locking brackets.

[0003] Active self-locking brackets are usually mainly of the snap type, with a spring piece lightly pressing the arch wire into the groove to increase friction to control the torque angle and axial inclination angle. Passive self-locking brackets are mainly of the sliding cover type, with the sliding cover covering the main arch wire to achieve light force correction without contacting the main arch wire and quickly align the teeth.

[0004] In clinical reality, the two types of brackets cannot be used simultaneously, and clinicians cannot make diverse selections according to the treatment situation at that time. To achieve the ideal effect, they can only alternately disassemble and bond the main and passive brackets, which wastes time and the brackets are expensive. Summary of the Invention

The whole device is pasted on the tooth surface by applying a layer of resin binder on the bottom surface of the bracket base 1. A retractor can be externally connected to the limit block 14 to facilitate adding rubber bands to control orthodontics. After determining the appropriate first arch wire 9 or second arch wire 10, a pointed cone tool is obliquely inserted between the rocker block 20 and the fulcrum block 22 in the insertion groove 21, and then the rotating column 19 is pried, so that the pin column 18 moves downward. Then, a bias square tool is inserted into the arc groove 13 to pry the locking piece mechanism, so that the locking piece mechanism is opened. The appropriate first arch wire 9 or second arch wire 10 is placed, and the locking piece mechanism is pushed into the chute mechanism. The sliding column 6 abuts against the limit block 14, and the clamping groove 24 at the bottom of the sliding column 6 coincides with the pin slot 17. The pin column 18 in the pin slot 17 moves upward under the action of the spring 23 to engage the sliding column 6, making it not easy to fall off, so that the first arch wire 9 and the second arch wire 10 are fixed more tightly.
