Abstract

The present disclosure relates to an orthodontic wire comprising: a wire disposed along teeth to be used for orthodontics; an end formed at the wire; and an end protection part positioned at the end to protect oral tissue against damage.

Description

Orthodontic wire

The present disclosure relates generally to orthodontic wires, and more particularly, to orthodontic wires for preventing damage to oral tissue.

This section provides background information related to the present disclosure which is not necessarily prior art.

1 is a view for explaining the principle of orthodontics.

Referring to Figure 1, there is a tooth 10 for the purpose of correction, the bracket 20 is attached to the surface of the tooth (10). One side of the bracket 20, that is, a fixed circle (fixed or reference point) on the left in the drawing, the tooth 10 is moved from the right to the left by the arch wire 30 connecting the bracket 20 and the fixed circle Can be.

The tooth 10 moves in one direction along the arch wire 30 based on the fixed circle. At this time, the bone tissue of the bone surrounding the tooth 10 in the direction in which the tooth 10 moves is gradually absorbed, and new bone tissue is formed on the opposite side to fill the empty space. That is, the process of disappearing and generating bone cells is repeated and the tooth 10 can move.

Figure 2 is a view for explaining a conventional dental correction method. 2, the orthodontic bracket 20 is fixed to the surface of the tooth 10, and the brackets 20 are connected by the arch wire 30. In particular, when the bracket 20 is directly attached to the molar teeth, the bracket 20 may easily fall due to various reasons such as chewing force. Therefore, a separate device in a ring shape called a band is used for molar teeth, and a separate bracket device such as a tube may be welded to the surface of the band.

The arch wire 30 may form an elastic portion 32 or may use a rubber band 40 to give a continuous tension to the tooth 10. The elastic part 32 may be formed by bending a portion of the arch wire 30 in various shapes such as a U-shaped, P-shaped, or R-shaped, and may have a slight tension or twist between the fixed circle and the tooth 10. By forming a torsion, the position of the tooth 10 can be moved, and the posture of the tooth 10 can be changed. In addition, the rubber band 40 can help the movement of the tooth 10, and has the advantage that the patient can be inserted and removed by themselves.

3 is a view for explaining a conventional orthodontic process. 1 and 3, the tooth 10 includes a root 2, where the root 2 of the tooth 10 may be equal to or longer than the portion exposed from the gum. However, as shown, the bracket 20 is attached to the exposed portion of the tooth 10, the point where the bracket 20 is attached is located above the center of the tooth (10). Therefore, while the tension acts on the arch wire 30, only the upper portion of the tooth 10 moves, and as a result, the tooth 10 may be inclined to one side (a). The conventional practitioner can be bent to the arch wire 30 connected to the elastic portion 32, when the tooth 10 is inclined to one side to adjust the tilt of the tooth (Angulation). For example, if the tooth 10 is inclined to the left, the operator may bend the elastic portion 32 and the archwire 30 in opposite directions to form counter torque (b) and the tooth 10 ) Can return to the original position under the opposite torque (c).

4 is a view showing an example of the orthodontic device shown in Korea Patent Publication No. 10-1565803.

The orthodontic device 1 comprises an adhesive 20 and a wire 30. The wire 30 is provided to correspond to the teeth to be corrected 10 of the teeth 10 of the upper teeth group 11 or the teeth 10 of the lower teeth group 12. In particular, the wire 30 may be disposed on the labial or lingual side of the tooth 10. At this time, the upper tooth group 11 refers to a group of a plurality of teeth 10 provided in the upper jaw. In addition, the lower tooth group 12 refers to a group of a plurality of teeth 10 provided in the lower jaw.

In particular, the adhesive 20 is attached to the tooth surface of the tooth 10 to the minimum area, and the tooth surface and the transition part to maintain a smooth curved surface so that food is not easily attached to the tooth 10 can be protected. And, since the tooth 10 is not widely polished, tooth decay does not occur at a portion to which the adhesive 20 is attached.

In addition, for aesthetics, the adhesive 20 may be formed in the color of the tooth 10 and the shape of the tooth 10. In addition, the adhesive 20 does not have a discomfort when contacting the gums such as resin, and is made of a harmless material.

At this time, the wire 30 is made of the length of the entire tooth distance of the upper teeth group 11 or the lower teeth group 12.

In other words, the wire 30 is provided to span the entire tooth 10 of the same dentition that needs to be corrected. The wire 30 may vary in type, diameter, or thickness of the metal according to the degree of correction of the tooth 10, that is, the direction and amount of movement of the tooth. The wire 30 serves to correct the dentition of the tooth 10 by applying a side pressure or twisting force to the tooth 10 corresponding to the orthodontic treatment. The wire 30 may be applied to various materials and may be formed of a shape memory alloy. In particular, the wire 30 according to the present invention is applicable in the state in which the tooth 10 is extracted or not extracted.

In addition, the adhesive 20 is provided to correspond to the tooth 10 to be corrected, by increasing the contact area with the tooth surface for the movement of the tooth, it is possible to reduce the correction period of the tooth (10).

When the teeth are not even, the thicknesses of the adhesives 20 are different from each other so that the wires 30 may be disposed at a uniform curvature or a set curvature, and thus the distance from the tooth surface may be adjusted.

As shown in FIG. 4, the end of the wire 30 may be sharply formed. The movement of the wire 30 occurs while chewing the food, there is a problem that the wire 30 causes damage to the oral tissue. In order to prevent this, wax or resin is also inserted into the end of the wire 30, which is not completely fixed, there is a problem that brings back damage to the oral tissue.

This is described later in the section titled 'Details of the Invention.'

When the end protection unit 130 is formed of a material different from the wire 110, the end protection unit 130 is not well coupled with the wire 110. Therefore, the end 120 is formed with a contact strengthening unit 140 to widen the contact area with the end protection portion 130. The contact reinforcing part 140 may form the contact area of the end 120 by grinding, sanding, and chemical etching the end 120. In addition, when the wire 110 is formed of a mold, the mold may be manufactured so that the contact reinforcing portion 140 is provided at the end 120 of the wire 110.

An end protection part 130 is formed to surround the contact reinforcement part 140. The end protection part 130 may fall well even if it is in close contact with the self-producing activity, and thus increases the contact area between the end protection part 130 and the contact reinforcing part 140 through the contact reinforcing part 140.

A contact reinforcing part 140 is formed at the end 111 of the wire 110, and an end protection part 130 may be attached, and the material of the end protection part 130 may be applied to the contact reinforcing part 140. have. The end protection part 130 may be formed of a metal, a polymer material, or the like. For example, the polymer material may be a resin, wax, rubber, or the like. The end protection part 130 may be formed in a spherical shape. Various shapes of the end protection unit 130 will be described with reference to FIGS. 8 to 9.

As shown in FIG. 6A, the contact reinforcing part 140 may be formed to increase the contact area with the end protection part 130.

As shown in FIG. 6 (b), the contact reinforcement unit 140 may include one or more convex protrusions 141 or one or more concave grooves 142.

As illustrated in FIG. 6C, the shape of the contact reinforcement unit 140 may not be limited.
