DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tooth for orthodontic treatment according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a strip for orthodontic treatment according to an embodiment of the present invention.

A tooth for orthodontic treatment according to a preferred embodiment of the present invention comprises:

A body 10 having a transverse frame 12 and a pair of longitudinal frames 14 extending downward from both ends of the transverse frame 12;

A pair of holders (20) coupled to a lower end of the pair of vertical frames (14);

An abrasive blade 30 having both ends fixed to the pair of holders 20; And

And a handle (40) extending laterally to any one of the pair of holders (20).

Referring to FIG. 2, the body 10 includes a horizontal frame 12 and a vertical frame 14. The vertical frame 14 extends downward at both ends of the horizontal frame 12, and the horizontal frame 12 and the vertical frame 14 have a shape of '┏ ┓' as a whole.

That is, the body 10 is formed with a horizontal frame 12 and a vertical frame 14 integrally formed as a whole, and the pair of holders 20 are formed at the lower end of the vertical frame 14 .

The body 10 has a reinforcing portion 16 formed along the transverse frame 12 and the vertical frame 14. The reinforcing portion 16 also has a shape of '┏ ┓' as a whole.

It is preferable that the horizontal frame 12 and the vertical frame 14 constituting the body 10 are made of a metal plate 1 having a predetermined thickness, 1) is formed by embossing along the longitudinal center thereof to prevent the plate 1 from being warped. If necessary, the reinforcing portion 16 may be formed in plural.

The holder 20 is positioned between the body 10 and the abrasive blade 30 and fixes the abrasive blade 30 to the body 10.

The holder 20 is integrally formed downwardly from a lower end of the pair of vertical frames 14. The vertical frame 14 is formed of a metal plate 1 having a predetermined thickness The holder 20 is formed by extending the plate 1. In this case,

The holder 20 is wrapped around the lower end of the abrasive blade 30 so as to surround both sides of the abrasive blade 30 and the abrasive blade 30 is pressed between the holders 20.

That is, the holder 20 is bent in such a manner as to enclose both sides and the lower end face of the abrasive blade 30, so that the three faces of the abrasive blade 30 except for the upper face are in contact with the holder 20, It is possible to prevent deviation.

The holder 20 may be provided with a pressing portion 22 having a predetermined depth on one side or both sides of the holding blade 20 by pressing the polishing blade 30 to prevent the abrasive blade 30 from coming off, (22) can be formed into various shapes according to need, such as points, lines, curves or circles.

The holder 20 can be fixed to the abrasive blade 30 by an adhesive or welding or the like and the abrasive blade 30 is restrained by the holder 20 in three directions.

The abrasive blade 30 is a sheet of metal material having a predetermined thickness and is coated with diamond powder on the outer surface as required.

As shown in FIG. 2, the abrasive blade 30 may be formed with a plurality of pores 32 to prevent deformation due to heat generated by friction with the tooth surface.

The abrasive blade 30 may form an insertion hole or an insertion hole 34 into which the pushing portion 22 can be inserted and the abrasive blade 30 compressed in the holder 20 may be inserted into the insertion hole 34, It is possible to prevent the flow of the fluid.

At both end portions in the longitudinal direction of the abrasive blade 30, a step (not shown) may be formed to prevent the holder 20 from moving in the longitudinal direction while being pressed on the holder 20.

The handle 40 is coupled to one of the pair of holders 20 as a portion connecting the body 10 to which the abrasive blade 30 is fixed to the dental handpiece.

The handle 40 may be formed in various shapes so as to be combined with a dental handpiece. In an embodiment of the present invention, the plate material 1 is rolled so as to have a hollow therein.

The handle 40 is integrally extended from the holder 20 in the lateral direction. Specifically, the body 10, the holder 20, and the handle 40 are integrally formed as a single component .

4A to 4C, the body 10, the holder 20, and the handle 40 may be cut into a single boom shape integrally formed with the plate 1, and the cut portion may be cut into punching, And then bonded to the polishing blade 30, it is possible to efficiently produce a tooth for orthodontic treatment.

The following effects can be expected in the orthodontic strip according to the preferred embodiment of the present invention.

The toothbrushing blade is not separated from the body 10 during the orthodontic treatment because the abrasive blade 30 is fixed to the holder 20 coupled to the body 10, The grinding blades 30 can be more stably fixed.

And a reinforcing portion 16 formed by embossing along the longitudinal center of the plate 1 on a body 10 made of a metal plate 1 having a predetermined thickness, It is possible to prevent warping of the base 10.

In addition, the abrasive blade 30 has a plurality of perforations 32 to prevent deformation due to heat generated by friction with the tooth surface.

As described above, the present invention is not limited to the above-described embodiments, but may be applied to other types of orthodontic appliances. It will be understood by those of ordinary skill in the art that various changes and modifications may be made without departing from the spirit of the invention.
