    Best Mode An orthodontic strip according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
    Figs. 1 to 3 show the orthodontic strip according to an embodiment of the present invention.
    The orthodontic strip according to the preferred embodiment of the present invention comprises: a body 10 having a horizontally extending frame portion 12 and a pair of vertically extending frame portions 14 extending downwardly at the opposite ends of the horizontally extending frame portion 12 extend; a pair of holders 20 each coupled to the lower ends of the pair of vertically extending frame portions 14; an abrasive sheet 30 attached at its opposite ends to the pair of holders 20; and a handle 40 coupled to one of the two holders 20.
    Referring to FIG. 2, the body 10 includes the horizontally extending frame portion 12 and the vertically extending frame portions 14. The vertically extending frame portions 14 extend downwardly from the opposite ends of the horizontally extending frame portion 12 and the horizontally extending frame portion 12 and the vertically extending frame portions 14 form substantially an inverted U-shape.
    In other words, by integrally forming the horizontally extending frame portion 12 and the vertically extending frame portions 14, the body 10 is formed to have an inverted U-shape substantially, and the pair of holders 20 are vertical to the lower ends, respectively extending frame sections 14 coupled.
    Further, the body 10 is provided with a reinforcing portion 16 formed along the horizontally extending frame portion 12 and the vertically extending frame portions 14. The reinforcing portion 16 also has an inverted U-shape substantially.
    Further, the horizontally extending frame portion 12 and the vertically extending frame portions 14 having the body 10 may be made of a metal plate 1 having a predetermined thickness, and the reinforcing portion 16 may be formed by embossing along a longitudinal centerline of the body 10 be to thereby prevent deformation of the metal plate 1. If necessary, the reinforcing portion 16 may be formed in plural.
    The holders 20 are provided between the body 10 and serve to secure the abrasive sheet 30 to the body 10.
    The holders 20 may be formed integrally downwardly from the lower ends of the pair of vertically extending frame portions 14. When the vertically extending frame portions 14 are made of the metal plate 1 having the predetermined thickness, the holders 20 are formed integrally with the metal plate 1.
    The holders 20 are bent upward while surrounding a lower end of the abrasive sheet 30 such that the holders 20 surround opposite sides of the abrasive sheet 30, and the abrasive sheet 30 is pressed between the holders 20.
    In other words, the holders 20 are bent such that the same opposite side surfaces and a lower end surface surround the abrasive sheet 30, whereby the abrasive sheet 30 is in contact with the holders 20 on three surfaces outside an upper end surface thereof. Thus, it is possible to prevent the abrasive sheet 30 from separating in three directions.
    In order to prevent separation of the abrasive sheet 30, each of the holders 20 may be provided with a compressing portion 22 having a predetermined depth and formed on one side or both sides thereof which press against and surround the abrasive sheet 30. The compressing portion 22 may be formed in different shapes as needed, e.g. For example, points, lines, curves, circles, etc.
    The holders 20 may be additionally fixed to the abrasive sheet 30 by using an adhesive or by welding or the like, and the abrasive sheet 30 is restricted by the holders 20 in three directions. Thus, it is possible to achieve stable attachment of the abrasive sheet 30.
    The abrasive sheet 30 is a sheet having a predetermined thickness. If necessary, an outer surface of the abrasive sheet 30 may be coated with diamond powder.
    As shown in Fig. 2, the abrasive sheet 30 may be provided with a plurality of perforations 32 so as to prevent the abrasive sheet 30 from being deformed by heat generated by friction with the tooth surface.
    The abrasive sheet 30 may be provided with an insertion recess (not shown) or an insertion hole 34 into which the compressing portion 22 is inserted. In this case, it is possible to additionally prevent the abrasive sheet 30 pressed into the holders 20 from deviating in position.
    The abrasive sheet 30 may be provided at longitudinally opposite ends thereof with a step (not shown) such that the abrasive sheet 30 is prevented from deviating in position in a longitudinal direction while being pressed into the holders 20.
    In addition, the handle 40 may be formed in different shapes to be mated with a tooth handpiece. In the embodiment of the present invention, the handle 40 is formed by rolling the metal plate 1 and has a coupling hole therein by which the handle 40 is assembled with the tooth handpiece.
    The handle 40 may be integrally formed by extending from the holders 20 in a lateral direction. More specifically, the body 10, the holders 20 and the handle 40 may be integrally formed as a single part.
    As shown in Figs. 4 to 6, the body 10, the holder 20 and the handle 40 may be cut from the metal plate 1 as an integrally formed single part. Then, the cut-out part is processed by punching, bending, etc., and then coupled with the abrasive sheet 30. Thus, it is possible to efficiently produce an orthodontic strip.
    The orthodontic strip according to the preferred embodiment of the present invention has the following effects: First, the abrasive sheet 30 can be prevented from separating from the body 10 during orthodontic treatment, since the abrasive sheet 30 is attached to the holders 20, 20 which are coupled to the body 10 is attached. More specifically, since the holders 20 surround the abrasive sheet 30 in three directions, the abrasive sheet 30 can be stably fixed. Further, since the body 10 made of the metal plate 1 having the predetermined thickness is provided with the reinforcing portion 16 formed by embossing along the body 10, it is possible to prevent the body 10 from being deformed during orthodontic treatment Longitudinal center line of the metal plate 1 is formed.
