As shown in these figures, the dental braces 100 according to an embodiment of the present invention, in particular, as a dental braces 100 to close the (closing) space, such as extraction space (101S) for orthodontics, The wires 110 for the correction of the wires and, for example, between the teeth 101 (101a, 101b) disposed on both sides with the extraction space 101S interposed therebetween for positioning the wires 110 to be movable. Positioning fixing portion 120 and the attraction force providing unit 130 for providing an attraction force to pull the teeth (101a, 101b) of both sides in the extraction space (101S) direction.

By such a configuration, by accurately closing the extraction space (101S) or the open space can improve the accuracy of the orthodontics, as well as the orthodontic can be improved by a simple configuration can also improve the efficiency of the orthodontic.

Referring to each configuration, first, the wire 110 of the present embodiment, as shown in FIG. 2, the

teeth

101a and 101b to which the fixing part 120 is mounted by being movably penetrated through the fixing part 120. Properly adjust the force between the teeth so that orthodontics can be made. That is, to provide a force for orthodontics, and also to provide a force for adjusting the position of the teeth (101a, 101b) will be described later.

The wire 110 may be provided as a round wire 110 having a circular cross section. In the case of the present embodiment, for example, it may have a value of 0.007 to 0.022 inches, preferably may be provided in 0.008 to 0.012 inches. The wire 110 has a relatively small diameter compared to the general diameter of the wire used in the related art, but can properly transmit force to the teeth to be corrected, and also minimizes foreign body feeling because the diameter is small. However, the diameter and shape of the wire 110 is not limited thereto.

The wire 110 may be made of a shape memory alloy so that the shape may be stored according to the shape of the

teeth

101a and 101b to be corrected. For example, a Ni-Ti alloy or the like that is harmless to a human body may be applied. For this reason, when the dental braces 100 are mounted on the

teeth

101a and 101b, the wire 110 may be deformed into a shape memorized shape so that the teeth may be straightened.

Meanwhile, as shown in FIGS. 1 and 2, the fixing part 120 of the present embodiment is mounted on the

teeth

101a and 101b disposed on both sides with the extraction space 101S therebetween, so that the wire 110 may be disposed. To move the position.

The fixing part 120 may include a first tube 121 and a second tube 123 disposed in parallel in two rows of

teeth

101a and 101b. The first tube 121 and the second tube 123 may have the same tube shape, and each may include a slot 120s so that the wire 110 is positioned but movable.

Referring to FIG. 3, for example, the inner diameter of the slot 120s of the first tube 121 is relatively larger than the diameter of the wire 110. Therefore, the wire 110 may move along the length direction in the slot 120s of the first tube 121. That is, the wire 110 is located inside the tube, but some degree of movement is possible.

The fixing part 120, that is, the first tube 121 and the second tube 123 may be formed of a resin. Resin is flowable without harming the human body, and because it hardens quickly over time, the fixing part 120 can be firmly attached to the

teeth

101a and 101b.

Referring to FIG. 2, the wire 110 is provided in a closed loop shape that is provided in two rows and is long, and one side of the wire 110 is disposed at both sides with the extraction space 101S. Are disposed to penetrate the first tube 121 and the second tube 123 provided in one of the teeth 101a, and the other side of the wire 110 is the other of the

teeth

101a and 101b. It may be disposed to penetrate the first tube 121 and the second tube 123 provided in 101b).

In order to enable such a configuration, the wires 110 are first disposed on the

teeth

101a and 101b, and then the

tubes

121 and 123 provided with the resin are mounted on the wires 110 arranged therebetween, so that the extraction space 101S is interposed therebetween. In addition, the teeth braces 100 for closing the extraction space 101S can be mounted on both

teeth

101a and 101b.

However, when the wire 110 is fixed by the first tube 121 and the second tube 123 provided with the resin, the inner side of the first tube 121 and the second tube 123 and the wire 110 closely adhere to each other. As a result, the wire 110 is firmly fixed to the

tubes

121 and 123, but cannot be moved. To this end, for example, by applying a non-toxic and saliva-soluble material to the outer surface of the wire 110, the

tubes

121 and 123 are mounted, and then the applied material is removed to remove the slots 120s of the

tubes

121 and 123. The wire 110 can be positioned to be movable. However, the configuration for movably positioning the wire 110 with respect to the slot 120s of the tube is not limited thereto.

On the other hand, since the wire 110 is made of a shape memory alloy as described above, by using the bending degree and bending direction of the wire 110 and the mounting structure of the fixing portion 120 corresponding thereto, The head and root portions can be relatively axially rotated.

Referring to FIG. 5, one side portion of the wire 110 having a central portion bent downward is disposed on the front surface of the tooth 101, and then the first tube 121 and the second tube 123 are inclinedly mounted on one side portion. In this case, since the wire 110 is intended to be unfolded in its original shape, the root portion of the tooth 101 may be subjected to a axial rotation force in the extraction space 101S direction. As such, the position of the wire 110 may be adjusted by axially rotating the head portion or the root portion of the tooth 101 according to the bending direction and the degree of bending.

In addition, the position adjustment of the tooth 101 may be performed along the mutual spacing and the arrangement direction of the first tube 121 and the second tube 123. When the first tube 121 and the second tube 123 are relatively spaced apart from each other, a larger axial rotational force may be applied to the tooth 101 even though the same wire 110 is the same size. In addition, as the diameter of the wire 110 increases, the axial rotational force applied to the tooth 101 may be increased.

Meanwhile, referring to FIG. 4, in the case of the dental braces 100 of the present embodiment, the

teeth

101a and 101b disposed at both sides with the extraction space 101S interposed therebetween to close the extraction space 101S are extracted space. It may further include a manpower provider 130 pulling in the (101S) direction.

The manpower providing unit 130 of the present embodiment may be fixed to one tooth 101a as the compression coil spring and the other end to the other tooth 101b. Resin may be used to fix both ends of the manpower providing unit 130. Here, the both ends of the manpower providing unit 130 of the teeth (101a, 101b) adjacent to the extraction space 101S so that the manpower providing unit 130 pulls the teeth (101a, 101b) in the direction of the extraction space 101S as a whole. It may be mounted at one side to form a central portion, that is, a center of gravity. However, the type and mounting structure of the manpower providing unit 130 is not limited thereto, and if it is possible to pull into the extraction space 101S of the

teeth

101a and 101b, other types or mounting structures may be applied.

On the other hand, in the following, the dental orthodontic method for closing the extraction space 101S of the dental braces 100 having the above-described configuration will be described schematically.

In the tooth straightening method of the dental braces 100 according to the embodiment of the present invention, as described above, the wire 110 is disposed on the

teeth

101a and 101b disposed at both sides with the extraction space 101S interposed therebetween. And a fixing part for mounting the first tube 121 and the second tube 123 to the

teeth

101a and 101b so that the wire 110 is movably positioned on the

teeth

101a and 101b. It may include a step.

In the wire disposing step of the present embodiment, as shown in FIG. 5, after bending is formed on the wire 110, the wire 110 may be disposed on the tooth 101. As described above, when it is desired to axially rotate the root portion of the tooth 101, the center portion of the wire 110 may be bent downward as shown in FIG. 5, and conversely, the head portion may be axially rotated with respect to the root portion of the tooth 101. In this case, the center portion of the wire 110 may be bent upward, and then the wire 110 may be disposed.

Meanwhile, in the fixing part mounting step of the present embodiment, the first tube 121 and the second tube 123 may be mounted on the tooth 101 in accordance with the inclined direction of the wire 110. That is, when the wire 110 is bent, one side portion of the wire 110 also faces the inclined direction, and correspondingly, the first tube 121 and the second tube 123 may be mounted on the tooth 101. It is.

When the mounting of the fixing part 120 is completed, the wire 110 is restored to a memorized shape, that is, an unfolded state. At this time, a force for rotation of the shaft is applied to the tooth 101 on which the fixing part 120 is mounted, so that the tooth ( Position adjustment of 101 may be made.

As described above, according to one embodiment of the present invention, the orthodontic treatment for closing the space between the

teeth

101a and 101b, for example, the extraction space 101S, can be performed by a simple configuration excluding the bracket so that the efficiency of the orthodontic treatment is improved. In addition, the

teeth

101a and 101b disposed on both sides of the space 101S may be evenly distributed in the space direction, thereby improving reliability of orthodontic teeth.

On the other hand, the present invention is not limited to the described embodiments, it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
