Flip type orthodontic bracket with variable arch wire slot

Abstract

The invention discloses a flip type orthodontic bracket with a variable arch wire slot. The flip type orthodontic bracket comprises a bracket main body and a flip, wherein the bracket main body is provided with the arch wire slot and a limiting mechanism; the limiting mechanism comprises a driving component and a push plate, and the push plate is arranged in the arch wire slot; and the pivot partof the flip is in transmission connection with the driving component, and the driving component is in transmission connection with the push plate. According to the orthodontic bracket, due to the limiting mechanism, a cover body is used for driving the limiting mechanism to adjust the arch wire accommodating space of the arch wire slot, and when the cover body is closed, the limiting mechanism canbe used for reducing the arch wire accommodating space in the arch wire slot and reducing the clearance of the arch wire groove, so that precise expression of torque of an arch wire is ensured, and the orthodontic effect of the orthodontic bracket is enhanced; and when the cover body is opened, the arch wire accommodating space is restored to the original size by the arch wire slot, so that an enough space is provided for in and out of the arch wire.

Description

technical field [0001] The invention relates to the field of dental orthodontic treatment equipment, in particular to a flip-type orthodontic bracket with a variable arch wire slot. Background technique [0002] Orthodontic brackets are generally used in orthodontic treatment to move one or more teeth in a patient's dentition from an initial position to a desired position, and elastic archwires are usually used to connect the brackets for growing the teeth toward the desired position. Apply force over time. [0003] However, there is generally a problem in the existing orthodontic brackets: the size of the arch wire is generally smaller than the size of the arch wire slot. It is difficult for the arch wire to enter / exit the slot; and the size of the arch wire is smaller than the size of the arch wire slot, which will inevitably leave a gap between the inner wall of the arch wire slot and the arch wire, which directly affects the accurate expression of the bracket preset dat...

AI Technical Summary

Problems solved by technology

[0003] However, there is generally a problem in the existing orthodontic brackets: the size of the arch wire is generally smaller than the size of the arch wire slot. It is difficult for the arch wire to enter / exit the slot; and the size of the arch wire is smaller than the size of the arch wire slot, which will inevitably leave a gap between the inner wall of the arch wire slot and the arch wire, which directly affects the accurate expression of the bracket preset data and affects the correction. Treatment and effect

This patent application requires the square wire extrusion roller to enter the archwire slot, which will inevitably cause pressure and damage to both the tooth and the bracket itself

Furthermore, the continuous pressure of the shrapnel makes it inconvenient to take out the arch wire

That is to say, this patent application also has the technical problem of being inconvenient to put in or take out the arch wire

Moreover, in this patent, only when the size of the archwire is larger than the distance between the rollers (effective groove size), the roller can work effectively. For the case where the size of the archwire is smaller than the distance between the rollers (effective groove size), the roller will fail

[0008] Therefore, there is no orthodontic bracket that reasonably solves the above-mentioned technical problems at present.
