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 to

Example Embodiment

[0051]Example 1

[0052]Such asFigure 1-Figure 6 As shown, the flip-type orthodontic bracket of this embodiment 1 includes a bracket body 10, a flip 20, and a bottom plate 30. The bottom plate 30 is arranged at the bottom of the bracket body 10 for bonding with the tooth surface.

[0053]Specifically, the bracket body 10 is provided with an archwire groove 13, a limiting mechanism and a sliding component. The archwire groove 13 divides the bracket body 10 into two, including a first bracket wing 11 protruding in the jaw-gingival direction and A second bracket wing 12 protruding in the gingival-jaw direction.

[0054]Wherein, the middle part of the gingival surface of the first bracket wing 11 is recessed to form a receiving groove 113, and the receiving groove 113 accommodates the screwed part of the flip cover 20. The settling surface of the receiving groove 113 is the bottom surface 1132 of the receiving groove 113. The two ends of the receiving groove 113 in the mesio-distal direction are...

Example Embodiment

[0075]Example 2

[0076]Such asFigure 7-10As shown, the flip-type orthodontic bracket of the second embodiment includes a bracket body 410, a flip 420, and a bottom plate. The bottom plate is arranged at the bottom of the bracket body 410 for bonding with the tooth surface.

[0077]Specifically, the bracket body 410 is provided with an archwire groove 413 and a limiting mechanism. The archwire groove 413 divides the bracket body 410 into two, including a first bracket wing 411 protruding in the jaw-gingival direction and a gingival-facing The second bracket wings 412 protruding in the jaw direction.

[0078]The middle part of the gingival surface of the first bracket wing 411 is recessed to form a receiving groove, and the receiving groove accommodates the screw connection portion 421 of the flip cover 420. The second bracket wing 412 is provided with a buckling position 4121 and a receiving cavity 4123 for placing a limiting mechanism. The buckling position 4121 matches the buckling portion...

Example Embodiment

[0092]Example 3

[0093]Such asPicture 11 As shown, the flip-type orthodontic bracket of the third embodiment is substantially the same as that of the second embodiment, and the difference is that the driving member of the third embodiment is different from the driving member of the second embodiment.

[0094]The driving components of the third embodiment are the pressure block 5151, the connecting rod 5155 and the return spring 5157. The pressure block 5151 is accommodated in the receiving cavity 5123 of the bracket body, and the return spring 5157 is arranged between the pressure block 5151 and the bottom of the receiving cavity 5123. The pressure block 5151 is maintained at the initial position. The tongue side of the pressure block 5151 is inclined, and the contact surface of one end of the connecting rod 5155 with the inclined surface of the pressure block 5151 is also inclined. The pressure block 5151 matches the connecting rod 5155, and the connecting rod The other end of the 5155 ...

Abstract

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

Description

technical field [0001] The invention relates to the field of dental orthodontic treatment equipment, in particular to a clamshell type orthodontic bracket. 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 data and affects the correcti...
