The orthodontic strip according to the present invention may include a handle coupled to a side of any one of the pair of holders or integrally formed on the side of any one of the pair of holders.
In the orthodontic strip according to the present invention, the body may be provided with a reinforcing portion formed along the horizontal frame and the vertical frames.
In the orthodontic strip according to the present invention, the body may be made of a plate having a predetermined thickness, and the reinforcing portion may be formed by embossing along a longitudinal direction of the plate.
In the orthodontic strip according to the present invention, the holders may be bent upward while surrounding a lower end of the grinding blade such that the holders surround opposite sides of the grinding blade, and the grinding blade may be pressed between the holders.
In the orthodontic strip according to the present invention, each of the holders may be provided with a compressing portion having a predetermined depth such that the grinding blade is prevented from separating.
In the orthodontic strip according to the present invention, the grinding blade may be provided with an insertion recess or an insertion hole, into which the compressing portion is inserted.
In the orthodontic strip according to the present invention, the grinding blade may be provided with a plurality of perforations.
In the orthodontic strip according to the present invention, the handle may be formed by rolling the plate extending from the body.
As described above, an orthodontic strip according to the present invention can be expected to have the following effects.
First, a grinding blade is fixed to the holders coupled to the body, and thus it is possible to prevent the grinding blade from separating from the body during orthodontic treatment.
Second, a reinforcing portion is formed on the body, and thus it is possible to prevent the body from warping during orthodontic treatment.
An orthodontic strip according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
The orthodontic strip according to the preferred embodiment of the present invention includes:
a body 10 having a horizontal frame 12 and a pair of vertical frames 14 extending downward from opposite ends of the horizontal frame 12;
a pair of holders 20 coupled to lower ends of the pair of vertical frames 14, respectively;
a grinding blade 30 fixed at opposite ends thereof to the pair of holders 20; and
a handle 40 laterally coupled to any one of the pair of holders 20.
Referring to
In other words, the body 10 is formed to have substantially an inverse U-shape by integrally forming the horizontal frame 12 and the vertical frames 14, and the pair of holders 20 are coupled to the lower ends of the vertical frames 14, respectively.
Further, the body 10 is provided with a reinforcing portion 16 formed along the horizontal frame 12 and the vertical frames 14. The reinforcing portion 16 also has substantially an inverse U-shape.
Further, the horizontal frame 12 and the vertical frames 14 comprising 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 center line of the body 10 to thereby prevent warping of the 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 fix the grinding blade 30 to the body 10.
The holders 20 may be integrally formed downwardly from the lower ends of the pair of vertical frames 14. When the vertical frames 14 are made of the metal plate 1 having the predetermined thickness, the holders 20 are formed integrally with the plate 1.
The holders 20 are bent upward while surrounding a lower end of the grinding blade 30 such that the holders 20 surround opposite sides of the grinding blade 30, and the grinding blade 30 is pressed between the holders 20.
In other words, the holders 20 are bent in such a manner as to surround opposite side surfaces and a lower end surface of the grinding blade 30, whereby the grinding blade 30 is in contact with the holders 20 on three surfaces except for an upper end surface thereof. Thus, it is possible to three-directionally prevent the grinding blade 30 from separating.
In order to prevent separation of the grinding blade 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 that press and surround the grinding blade 30. The compressing portion 22 may be formed into various shapes as required, such as points, lines, curves, circles, etc.
The holders 20 may be additionally fixed to the grinding blade 30 by using an adhesive or welding or the like, and the grinding blade 30 is constrained by the holders 20 in three directions. Thus, it is possible to achieve stable fixing of the grinding blade 30.
The grinding blade 30 is a metal sheet having a predetermined thickness. If necessary, diamond powder may be coated on an outer surface of the grinding blade 30.
As shown in
The grinding blade 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 further prevent the grinding blade 30 pressed in the holders 20 from positionally deviating.
The grinding blade 30 may be provided at longitudinal opposite ends thereof with a step (not shown), such that the grinding blade 30 is prevented from positionally deviating in a longitudinal direction while being pressed in the holders 20.
The handle 40 serves to connect the body 10 to which the grinding blade 30 is fixed and a dental handpiece with each other, and is coupled to a side of any one of the pair of holders 20.
In addition, the handle 40 may be formed into various shapes to be assembled with a dental handpiece. In the embodiment of the present invention, the handle 40 is formed by rolling the metal plate 1 and has therein a coupling hole through which the handle 40 is assembled with the dental handpiece.
Moreover, the handle 40 is may be integrally formed by extending from the holders 20 in a lateral direction. Specifically, the body 10, the holders 20, and the handle 40 may be integrally formed as a single part.
As shown in
The orthodontic strip according to the preferred embodiment of the present invention can be expected to have the following effects.
First, since the grinding blade 30 is fixed to the holders 20 coupled to the body 10, the blade can be prevented from separating from the body 10 during orthodontic treatment. In particular, since the holders 20 surround the grinding blade 30 in three directions, the grinding blade 30 can be fixed more stably.
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 longitudinal center line of the plate 1, it is possible to prevent the body 10 from warping during orthodontic treatment.
Furthermore, since the grinding blade 30 is provided with the plurality of perforations 32, it is possible to prevent the blade from being deformed by heat generated by friction with the tooth surface.
The present invention relates to an orthodontic strip, and more particularly, to an orthodontic strip that comprises a blade for grinding a predetermined portion of a tooth surface to secure space between teeth during a dental procedure, and a body for fixing the blade, whereby it is possible to provide a structure in which the blade is prevented from separating from the body.
