Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the configuration and application according to an embodiment of the present invention. The following description is one of several aspects of the patentable invention and the following description forms part of the detailed description of the invention.

However, in describing the present invention, a detailed description of known functions or configurations will be omitted for clarity of the gist of the present invention.

1 is a view showing a state in which a dental braces attached to a tooth according to an embodiment of the present invention, Figure 2 is an enlarged view of a portion of Figure 1, Figure 3 is a perspective view of the orthodontic bracket shown in FIG. 4 is a side view of FIG. 3.

1 and 2, the dental braces 100 according to an embodiment of the present invention, the wire 110 having a rigidity for the correction of the teeth 101 and the front of the teeth 101 individually It may include a plurality of calibration bracket 120 is coupled and the wire 110 is coupled.

Here, the force between the orthodontic brackets 120 may be controlled by the wires 110 connecting the orthodontic brackets 120, and thus the teeth 101 may be corrected. That is, when the teeth 101 adjacent to each other need to be pulled inward, the wires 110 coupled to the orthodontic brackets 120 of the teeth 101 may be more taut to correct the teeth 101. .

Referring to each configuration, first, the wire 110 of the present embodiment is inserted into and coupled to each of the calibration brackets 120, as shown schematically in FIGS. 1 and 2, and each of the calibration brackets 120. Properly adjusting the force of the liver so that the correction of the teeth (101) is made.

The wire 110 may be provided to have various diameters, but in the present embodiment, for example, 0.14 inch may be provided. This is a small value compared to the general diameter of the wire used in the prior art because the diameter is relatively small can be easily coupled to the orthodontic bracket 120 and can also enhance the force transmission force.

However, the diameter of the wire 110 is not limited thereto and may be provided with a different diameter.

On the other hand, the calibration bracket 120 of the present embodiment, as shown in Figures 2 to 4, the bracket body 121 is formed through the insertion portion 130 for the coupling of the wire 110 to form a basic frame And a slot forming unit 140 forming a communication slot 141 formed in the direction of the insertion unit 130 from the outer surface of the bracket body 121.

By such a configuration, the wire 110 can be easily coupled to the orthodontic bracket 120 of the present embodiment in the oral cavity. In addition, the coupling of the wire 110 is easy, but the release of the coupling is not made arbitrarily can maintain a strong coupling force to the calibration bracket 120.

In the bracket body 121 of the present embodiment, as shown in FIGS. 2 to 4, the portion 121a attached to the front surface of the tooth 101 is flat and the portion to which the wire 110 is coupled is generally rounded. Shape, that is, curved surface shape. In addition, an insertion unit 130 to which the wire 110 is coupled may be provided at the center of the bracket body 121.

In detail, the bracket body 121 may be adhered to the front surface of the tooth 101 by an adhesive or the like. At this time, in order to increase the adhesion of the bracket body 121 to the teeth 101, the surface of the adhesive portion 121a of the bracket body 121 may be made of a net structure. However, the coupling method and the adhesive surface structure of the bracket body 121 to the tooth 101 is not limited thereto.

In addition, the bracket body 121 of the present embodiment has a curved surface as a whole. In other words, it has a shape that excludes angled portions as much as possible. Therefore, the foreign body feeling of the patient can be reduced. In addition, in the conventional case, the bracket may have an angled portion, so that a wound may be generated at the tip of the patient's tongue or the inner part of the lips. It can prevent the occurrence of wounds.

In addition, the bracket body 121 of the present embodiment may be manufactured integrally by a resin of translucent or transparent material. Therefore, when the tooth 101 is opened with the mouth open, a person who is orthodontized by exposing the metal bracket is conventionally sensitive to such a part. However, in the present embodiment, for example, the bracket body is made of a transparent resin. 121) can reduce the sensitivity of the person who has been calibrated. That is, compared with the conventional one, the aesthetics can be improved.

In addition, the manufacturing cost may be reduced to some extent by manufacturing the resin instead of the metal material.

On the other hand, the insertion portion 130 is formed penetrating in the lateral direction of the bracket body 121 of the present embodiment, has a hollow cylindrical shape corresponding to the shape of the wire 110 and the wire 110 to the insertion portion 130 After the insertion is performed, the position of the wire 110 with respect to the insertion unit 130 may be fixed by the adhesive.

As will be described later, the wire 110 of the present embodiment is provided to have a relatively small value compared to the diameter in order to increase the force transmission force, the insertion portion 130 to which the wire 110 is coupled is also of the wire 110 The penetration force of the wire 110 with respect to the insertion portion 130 may be strengthened by being formed to have a shape corresponding to the diameter.

On the other hand, in the past, since the wire is generally coupled in the lateral direction of the bracket (for example, the penetration direction of the insert), it is not easy to bond the bracket to the tooth first in the oral cavity, and then to connect the wire to the bracket. In this case, the wire 110 may be easily coupled to the insertion unit 130 of the bracket body 121 by the communication slot 141 formed by the slot forming unit 140 to be described later. In addition, when the coupling is completed, the insertion unit 130 is locked by the slot forming unit 140 so that the separation is not made arbitrarily.

Specifically, the slot forming unit 140 of the present embodiment forms the communication slot 141 in the direction of the insertion unit 130 from the outer surface of the bracket body 121, and by the communication slot 141. The wire 110 may be inserted in the thickness direction of the bracket body 121 rather than in the lateral direction.

However, the coupling of the wire 110 to the insertion unit 130 is made easily, but the movement of the wire 110 on the contrary, that is, the coupling of the wire 110 to the insertion unit 130 is not made arbitrarily. To this end, the communication slot 141 formed by the slot forming unit 140 has a shape in which the width is narrowed toward the insertion unit 130 from the outer surface of the bracket body 121.

More precisely, the communication slot 141 is formed from the bottom of the bracket body 121 in the direction of the insertion portion 130, that is, upwards, so that the operator inserts the wire 110 into the initial insertion portion of the communication slot 141 and then upwards. The wire 110 may be coupled to the inserting unit 130 by applying a force to the insert 130.

At this time, since the diameter of the wire 110 has a relatively large value compared to the width of the communication slot 141, when the wire 110 passes through the communication slot 141, the slot forming portion 140 must be opened and the wire When 110 is fully coupled to the insert 130, the slot forming unit 140 must return to its original state. To this end, as described above, the bracket body 121 including the slot forming unit 140 of the present embodiment may be made of a resin and may have a restoring force.

Meanwhile, the wire 110 may be inserted into the inserting portion 130 by the tapered shape of the communication slot 141. However, it is not easy to separate the wire 110 from the inserting portion 130 again. .

When the wire 110 is fully inserted into the insertion unit 130, the slot forming unit 140 closes the entrance of the communication slot 141 closest to the insertion unit 130, thereby again closing the communication slot 141 having a narrow width. The wire 110 cannot be decoupled through.

In other words, when the wire 110 is inserted into the insertion unit 130, the slot forming unit 140 serves to lock the insertion unit 130. Therefore, the wire 110 is firmly coupled into the insertion unit 130. Can be.

As such, in the present embodiment, when the wire 110 is inserted into the insertion unit 130 by the slot forming unit 140 forming the communication slot 141, the thickness is not in the lateral direction of the bracket body 121. Not only can be easily coupled, but once inserted, it is possible to maintain the position of the wire 110 with respect to the insert 130, thereby improving the reliability of the teeth 101 correction.

On the other hand, in the following, the procedure of the dental braces 100 according to an embodiment of the present invention will be described schematically.

First, the orthodontic brackets 120 are adhered to the front surface of the teeth 101 to be corrected, respectively. At this time, the orthodontic bracket 120 may be adhered to the front surface of the tooth 101 using an adhesive or the like.

Thereafter, the operator couples the wire 110 to the orthodontic bracket 120 while the patient is open. At this time, the wire 110 may be inserted into the insertion unit 130 through the communication slot 141 formed in the bracket body 121 of the calibration bracket 120.

Subsequently, the wires 110 are fixed to each of the calibration brackets 120. In this case, the wires 110 may be fixed to the insertion unit 130 through an adhesive or the like, as well as a separate fixing wire (not shown). The wire 110 may be fixed to the insertion unit 130 by using.

As such, according to an embodiment of the present invention, the wire 110 may be easily inserted into the insertion unit 130 through the communication slot 141 formed by the slot forming unit 140 as well as the insertion unit. When the insertion of the wire 110 to the 130 is completed, it is possible to prevent the disengagement of the wire 110 by the locking of the slot forming unit 140, and thus, of the wire 110 to the orthodontic bracket 120. There is an advantage to strengthen the bonding force.

In addition, the calibration bracket 120 is provided with a resin material of a transparent or semi-transparent material can not only improve the aesthetics but also reduce the manufacturing cost.

In the above-described embodiment, the case in which the communication slot is formed in the direction of the insertion part from the bottom of the bracket body has been described above. However, the present invention is not limited thereto, and it is obvious that the communication slot may be formed in the upper surface or the side.

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.
