In addition, the coating agent may dissolve in water.

As shown in these drawings, the orthodontic device 100 includes a wire 110 for the correction of teeth 101 and a coating agent coated on the outer surface of the wire 110 (120, see FIG. 2) And, fixing the wire 110 coated with the coating agent 120 to the surface of the tooth 101 and movably fixed along the longitudinal direction of the wire 110 130, that is, includes a resin can do.

Here, the fixing part 130 has flowability and hardens over time, and may be made of resin. However, it is not limited to this, and it is natural that other types of fixing parts 130 can be applied as long as they have flowability, harden over time, and are harmless to the human body. Hereinafter, the fixing part 130 will be described by naming it as resin.

With this configuration, the coating agent 120 is removed from the wire 110 after the resin is covered, and thus a gap G1 is generated between the fixing part 130 and the wire 110 to the fixing part 130. The wire 110 is movable in its longitudinal direction. Through this, the correction of the teeth 101 can be made.

Referring to each configuration, first, as shown in FIG. 1, the wire 110 is coupled to pass through the fixing part 130 fixed to the surface of the tooth 101, and each fixing part 130 is mounted. Correction of the teeth 101 is made by properly adjusting the force between the teeth 101.

The wire 110 has a structure in which the coating agent 120 is coated and the coated wire 110 is fixed to the surface of the tooth 101 by the fixing part 130.

Referring to FIG. 2, the wire 110 coated with the coating agent 120 is placed on the surface of the tooth 101, and then the wire 110 coated with the coating agent 120 is placed on the tooth 101 through a flowable resin. ) is fixed to the surface of At this time, the resin hardens on the surface of the tooth 101 to maintain its shape and forms the fixing part 130 .

Here, since the fixing part 130 is hardened while the wire 110 coated with the coating agent 120 is surrounded by the fixing part 130, the wire 110 is fixed to the fixing part 130 so that the wire 110 Movement may not occur. The coating agent 120 is for generating a gap G1 between the fixing part 130 and the wire 110, and after the resin is covered and hardened, the coating agent 120 is removed. That is, the coating agent 120 is removed from the surface of the wire 110. Therefore, since the fixing part 130 has a slot 130s through which the wire 110 passes, and the wire 110 has a smaller diameter than the inner diameter of the slot 130s of the fixing part 130, the wire 110 By being movable with respect to the fixing part 130, correction of the tooth 101 can be performed.

As described above, coating 120 is removed from wire 110 . In other words, before being covered by the fixing part 130, the wire 110 remains coated with the coating agent 120, but after being wrapped with the fixing part 130, the coating agent 120 is removed from the wire 110. .

To this end, the coating agent 120 may be provided with a material that melts at an oral temperature. That is, it does not melt at room temperature, but slowly melts in the range of intraoral temperature, and when the wire 110 is placed in the oral cavity and then the fixing part 130 is attached, the coating agent 120 can be naturally gradually removed from the wire 110. . Alternatively, the coating agent 120 may be a material that melts upon contact with saliva. The coating agent 120 is a material that interacts with the needle and can be removed from the wire 110 by melting when the needle comes in contact with it. Alternatively, it is natural that the coating agent 120 may be made of a water-soluble material. As shown in the second drawing of FIG. 2, after wrapping the wire 110 coated with the coating agent 120 with the fixing part 130, the coating agent 120 can be melted by providing a liquid such as water to the coating agent 120, Accordingly, the coating agent 120 may be removed from the wire 110 . The aforementioned coating agent 120 is made of a material harmless to the human body. The coating agent 120 removed from the wire 110 stays in the oral cavity, and since the coating agent 120 is made of a harmless material, it does not affect the human body. The coating agent 120 may be made of a material such as caramel, for example. After melting the caramel into a liquid, it is coated so as to surround the wire 110. And after placing the wire 110 coated with this coating 120 on the surface of the tooth 101 as shown in the first drawing of FIG. 2, the wire 110 is wrapped around the fixing part 130. Since caramel is a material that melts when it comes into contact with the needle, it can then be melted and removed from the wire 110. Then, the movement of the wire 110 relative to the fixing part 130 becomes possible. The material constituting the coating agent 120 is not limited thereto, and for example, the coating agent 120 may be provided with a material containing sugar or sugar alcohol.

Meanwhile, the wire 110 may adjust the moving force of the wire 110 relative to the fixing part 130 according to the coating thickness of the coating agent 120 .

When the coating agent 120 is coated relatively thickly on the wire 110, when the coating agent 120 is removed, a gap G1 between the wire 110 and the fixing part 130 occurs as much as the thickness of the removed coating agent 120. Therefore, the degree of movement of the wire 110 relative to the fixing part 130 may be relatively large, and conversely, when the coating agent 120 is coated relatively thinly on the wire 110, when the coating agent 120 is removed, the removed coating agent ( 120), the amount of movement of the wire 110 may be relatively small because the gap G1 (smaller gap than the above-mentioned gap) between the wire 110 and the fixing part 130 is generated by the thickness of the wire 110. Meanwhile, the moving force of the wire 110 relative to the fixing part 130 may be adjusted according to the diameter or width of the wire 110 . In other words, by adjusting the thickness of the coating agent 120 coated on the wire 110 or adjusting the size of the wire 110 itself, it is possible to adjust the moving force of the wire 120 with respect to the fixing part 130.

On the other hand, the fixing part 130, as described above, is hardened on the surface of the tooth 101 to fix the wire 110 to be movable. This fixing part 130 is provided with a flowable synthetic resin, and as shown in the second drawing of FIG. 2, it is applied to the surface of the tooth 101 in a round shape so as to surround the wire 110, so that the tooth 101 hardens on the surface of The fixing part 130 may be hardened on the surface of the tooth 101 by photopolymerization for several seconds. As described above, the fixing part 130 has a curved shape. This is to have a material and shape different from the brackets made of metal commonly used in the prior art. Due to the shape of the fixing part 130, even if the tongue or other parts of the oral cavity come into contact with the fixing part 130, it is possible to prevent an injury from occurring. In addition, since the flowable fixing part 130 is dropped on the surface of the tooth 101 and mounted on the surface of the tooth 101, the mounting process is very simple, and in addition, something like a bracket is attached to the surface of the tooth 101. If attaching causes pain, attaching the fixing part 130 is simple and can minimize pain. The fixing part 130 is mounted on the surface of the tooth 101, and then, as shown in the third drawing of FIG. In addition, it is possible to obtain a mounting state as shown in the fourth drawing of FIG. 2 by melting the coating agent 120 by applying the various methods described above. On the other hand, the orthodontic device 100 may be applied for the entire tooth 101 correction, but may be applied for partial tooth 101 correction as shown in FIG.

It may occur that the entire orthodontic appliance 100 needs to be replaced due to the detachment of the fixing part 130 or the like, or a part of the wire 110 may be incorrectly attached to the teeth 101 and need to be reattached. there is. However, in this case, since the coating agent 120 previously applied to the wire 110 may have all melted away, the liquid coating agent according to an embodiment for reattachment of the wire 110 is applied only to the corresponding portion of the wire 110. After application, re-attachment can be easily performed by applying the fixing part 120 on the corresponding part.

The composition, composition ratio, and manufacturing method of the liquid coating agent for reattachment of the wire 110 are as follows.

·PGA/purified water WATER: 30-40%

PGA can act as a gap shape by preventing water-soluble and light-curing adhesion between resin and wire.

The pigment can be easily distinguished during wire application.

Spices such as peppermint and menthol may be applied to give a refreshing feeling to the savory flavor unique to PGA.

Fluoride and xylitol can be applied to prevent tooth decay.

Gum arabic and dextrin can be applied for a thickening effect.

· Uniformly mix PGA and purified water (additive mixture less than 5%) at room temperature in a constant ratio using centrifugal force.

The material thus mixed is a translucent viscous liquid. (The color may change depending on the added pigment)

The viscosity of the substance must maintain a certain amount of viscosity so that it does not flow easily when used directly in the clinical oral cavity. (About 3000~4000cP)

Put the prepared material into a sterile syringe, close the lid, and store at room temperature.

Refrigerate after opening. When refrigerated, expose to room temperature one hour before use.

This is to ensure viscosity stability.

After use, close the cap, seal, and refrigerate.

How to use in clinical practice: After applying a temporary coating on the wire, curing the resin on it, and then washing it with water, it melts immediately and completes the formation of a gap that enables the operation of the orthodontic wire.

In a state where the wire is dried, the coating agent in a liquid state is uniformly applied with a constant force using a brush or an elastic body.

Resin is cured on top of it.

When washed with water, it melts immediately and forms a gap that can operate the orthodontic arch.

· This is to improve the inconvenience of having to use a new coated wire after removing the entire straightening device due to resin dropout during straightening using the existing coated wire.

· It is to manufacture an orthodontic device by using it directly in the oral cavity quickly for partial orthodontic treatment.

· It is for correcting the accuracy of the existing coating wire attachment position.

A method of using a dental orthodontic device includes the steps of coating the outer surface of a wire to place a coating agent, disposing the wire coated with the coating agent in the oral cavity, and injecting and curing a resin on the surface of the teeth to arrange a fixing unit. melting the coating to create a gap between the wire and the fixing part; and moving the wire longitudinally with respect to the fixing part.
