[0026] The utility model provides an orthodontic appliance 100 .

[0027] See also Figure 1-Figure 4 In one embodiment of the utility model, the orthodontic appliance 100 includes a plurality of appliance bodies 10, metal wires 30 and adjustment disks 20. The appliance bodies 10 are bonded to the outside of the teeth. The adjustment disk 20 is mounted on a side wall of each appliance body 10 away from the teeth. A positioning member 21 is provided in the adjustment disk 20. The positioning member 21 can rotate on the adjustment disk 20. A locking member 40 is provided on the appliance body 10. The locking member 40 abuts against the positioning member 21. A channel 26 is provided on the positioning member 21. The metal wire 30 passes through the channel 26 to connect adjacent adjustment disks 20.

[0028] In this embodiment, the brace body 10 and the adjustment disk 20 can be made of materials such as silicone, polyacrylic resin, etc., so that they have light adhesion, and the appropriate color can be selected according to personal preference; the adjustment disk 20 and the brace body 10 can be fixedly connected by screws, and the metal wire 30 can be nickel-titanium wire, which is a composite of nickel and titanium and is relatively soft. Once it is subjected to force, it will deform and rebound after deformation. The rebound force is relatively continuous and gentle, which helps to slowly align the teeth.

[0029] In one embodiment of the present utility model, the positioning member 21 includes a positioning portion 22 and a supporting portion 23, the positioning portion 22 is sleeved on the supporting portion 23, one end of the supporting portion 23 abuts against the appliance body 10, and the other end is exposed outside the adjusting disk 20, the channel 26 is arranged on the supporting portion 23, a first notch 24 is provided on the adjusting disk 20, the appliance body 10 is provided with a sliding groove 11 corresponding to the first notch 24, the locking member 40 is installed in the sliding groove 11 and passes through the first notch 24 to abut against the positioning member 21.

[0030] The appliance body 10 is provided with a depression 13, and the support portion 23 rests against the bottom of the depression 13, so that the channel 26 is flush with the surface of the appliance body 10, and the adjustment disk 20 is also provided with a second notch 25. The metal wire 30 passes through the channel 26 and then exits from the second notch 25 to be connected in series with the adjacent adjustment disk 20.

[0031] In this embodiment, the cross section of the positioning portion 22 is in a standard circular ring shape, and a plurality of first protrusions 27 are provided on the positioning portion 22, and a slot 28 is formed between two adjacent first protrusions 27. The locking member 40 is provided with a second protrusion 41, and the second protrusion 41 is stuck in one of the slots 28 to lock and fix the positioning member 21 so that it cannot rotate.

[0032] The support part 23 is cylindrical, and a cross notch is provided on one side wall of the support part 23 exposed outside the adjustment disk 20, so that the doctor can use a small cross screwdriver to rotate the positioning member 21. The number of the first notches 24 is two, and the two first notches 24 are symmetrically arranged. Correspondingly, the number of the sliding grooves 11 is also two, and a plurality of positioning holes 12 are provided in each sliding groove 11, and the plurality of positioning holes 12 are arranged linearly along the length direction of the sliding groove 11. The locking member 40 is positioned and fixed by the cooperation between the positioning screw 42 and the positioning hole 12. The positioning screw 42 can be a common hexagon socket set screw, and the locking member 40 is fixed and positioned by tightening the positioning screw 42 so that it cannot move.

[0033] It can be understood that when the positioning screw 42 is loosened, the locking member 40 can move in the sliding groove 11, and the locking member 40 is moved in a direction away from the first notch 24, so that the second protrusion 41 is disengaged from the corresponding slot 28. At this time, the positioning member 21 can be rotated by using a small cross screwdriver. During the rotation of the positioning member 21, the support portion 23 rotates, and the metal wire 30 located in the channel 26 is deformed by the twisting of the support portion 23. Because the metal wire 30 is a nickel-titanium wire with a memory recovery function, the deformation amount of the metal wire 30 can be changed by rotating the angle of the positioning member 21. The rotation angle of the positioning member 21 can be determined according to the inclination angle of the tooth. For example, if the inclination angle of the tooth is 15°, the positioning member 21 is rotated 15°, and one first protrusion 27 represents 5°, then the rotation amount of three first protrusions 27 needs to be rotated. It should be noted that in actual use, the rotation angle of the positioning member 21 is confirmed according to the actual operation, and its principle is only carried out here. The deformation amount of the metal wire 30 is determined by the different rotation angles of the positioning member 21, thereby completing the correction of teeth with different inclination angles.

[0034] After completing the adjustment of the positioning member 21, move the locking member 40 to make the second protrusion 41 stuck in the corresponding slot 28, and then tighten the positioning screw 42 to fix the locking member 40 so that it can re-position the positioning member 21 to prevent the positioning member 21 from rotating.

[0035] Working principle: the orthodontic appliance body 10 is bonded to the teeth, the metal wire 30 is first clamped in the channel 26, and then the adjustment disk 20 is fixedly connected to the orthodontic appliance body 10 with screws. When the deformation of the metal wire 30 needs to be adjusted, the positioning screw 42 is loosened, the locking member 40 is moved to make the second protrusion 41 disengage from the corresponding slot 28, and then the positioning member 21 is rotated with a small cross screwdriver. The metal wire 30 is deformed by the twisting of the positioning member 22. The rotation angle of the positioning member 21 can be determined according to the inclination angle of the teeth. The deformation of the metal wire 30 is determined by different rotation angles of the positioning member 21, thereby completing the correction of teeth with different inclination angles, and the applicability is high.

[0036] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
