Description

Braces for Orthodontic Braces {ORTHODONTIC BRACKET}

The present invention relates to a bracket for orthodontic treatment.

More particularly, the present invention relates to an orthodontic bracket capable of accurately positioning a wire by an orthodontic bracket before fixing a wire to a fixed portion, thereby improving the reliability of the orthodontic treatment, A calibration method is disclosed.

Generally, a non-uniform dental state or non-uniform malocclusion of teeth may cause developmental disorders of the teeth themselves, developmental disorders of the jaw, and the like.

People with irregular teeth or malocclusion can have their mouths blocked by their dental state when talking or laughing with others, and can be passive in interpersonal relationships, making it difficult to have a decent social life.

In addition, when food is consumed, food can not be uniformly crushed, and food may be stuck between teeth, resulting in various tooth diseases or digestive system diseases.

To solve this problem, orthodontic techniques for applying a constant force to the teeth and modifying the alveolar bone around the teeth and causing movement of the teeth have been applied.

A conventional general orthodontic appliance to which the orthodontic technique is applied includes a plurality of orthodontic brackets individually attached to the front of each tooth as disclosed in Korean Patent Application No. 10-2013-0064601, And wires for connecting and fixing them.

More specifically, the orthodontic bracket is provided with an insertion hole into which the wire is inserted, so that the orthodontic bracket can be bonded to the front of the tooth and then the wire can be connected to the orthodontic brackets in the oral cavity.

However, in order to apply force to the teeth by inserting wires into the orthodontic brackets, the teeth must be located on the same plane to some extent so that the orthodontic bracket can be mounted.

Otherwise, for example, if at least one of the plurality of teeth to be aligned is displaced to the lingual side, a step of forming a space for dislocating it in the opposite direction of the lingual side should be preceded.

To this end, the wire may be compressed into a coil shape and connected to an orthodontic bracket attached on at least one tooth displaced to the lingual side, or a coil spring may be wound around the outer circumferential surface of the wire inserted into the orthodontic bracket.

However, in the case of attaching the same orthodontic bracket attached to a tooth which is not dislocated to a tooth displaced to the lingual side, the space between the teeth on both sides of the lingually displaced tooth is narrow, There is a problem that the bracket can not be attached.

Even if there is a space in which the orthodontic bracket can be attached to the teeth displaced to the lingual side, there is a problem that the labor of a doctor or a patient is much higher than that of general teeth.

The orthodontic bracket attached to the teeth displaced to the lingual side is not provided with a stopper for preventing the accommodated wire from deviating in the opposite direction of the lingual side so that the coiled spring arranged to wind on the outer peripheral surface of the wire or the wire Or a coil spring for generating a stronger restoring force is loosened so as to surround the wire, thereby causing a side effect such as a patient feeling a foreign object.

In the case of attaching the same orthodontic bracket attached to a tooth which has not been dislocated to a tooth displaced to the lingual side, the space between the teeth on both sides of the lingually displaced tooth is narrow and the teeth displaced to the lingual side It is an object to be solved to prevent the problem that the orthodontic bracket can not attach.

It is another object of the present invention to solve the problem of reducing the labor of a physician or a patient who attaches the orthodontic bracket to a patient's teeth.

The orthodontic bracket attached to the teeth displaced to the lingual side is not provided with a stopper for preventing the received wire from deviating in the reverse direction of the lingual side so that the accommodated wire or the coil spring arranged to wind on the outer circumferential surface of the wire, Or a problem that a side effect such as a feeling of a foreign body feeling by the patient is released by loosening the coil spring which is provided to wrap the wire so as to generate a strong restoring force is solved

According to an aspect of the present invention, there is provided a bracket for orthodontic bracket for positioning a wire for calibration of a tooth, the bracket comprising: a body portion disposed on one surface of a tooth; A slot for accommodating a wire for supplying a first energy to the tooth, and a coil spring accommodated in the slot and surrounding the outer circumferential surface of the wire to supply a second energy to the tooth And the slot portion is provided in a U-shape in which the opposite side of the lingual side of the teeth is closed.

The bracket for orthodontic correction is characterized in that the ratio between the area of the body part contacting the tooth and the at least one surface of the tooth in which the body part is disposed satisfies the following relational expression.

[Relational expression]

1/15? A / B? 1/10

A: the area of the face of the body portion which is in contact with the teeth

B: area of at least one surface of the teeth

Further, it is possible to provide the bracket for orthodontic treatment, wherein the slot portion is inclined at a predetermined angle.

In addition, the slot portion may be formed at an angle of inclination of the coil spring mounted on the slot portion

And the wire positioning oil is inclined at the same angle as the wire positioning oil

Can be provided.

Further, the length of the longitudinal section of the body section may be two to three times the length of the transverse section of the body section.

According to the embodiment of the present invention, since the area of the body of the bracket for orthodontic bracket is small and the space between the teeth on both sides of the lingually displaced tooth is narrow, it is possible to attach the bracket for orthodontic treatment to a desired position have.

Further, the present invention can provide a bracket for orthodontic treatment having a relatively small cross-sectional area, thereby reducing the labor of a physician or a patient affixing to a patient's tooth.

Further, the shape of the slot portion of the orthodontic bracket may be U-shaped closed on the side opposite to the lingual side of the tooth, so that the coil spring arranged to wind on the outer circumferential surface of the wire or the accommodated wire may move away from the lingual side, A coil spring for generating a stronger restoring force is loosened to prevent a side effect such as a patient feeling a foreign body feeling.

1 and 2, a bracket 100 for orthodontic braces according to an embodiment of the present invention includes a body 110 that is disposed on one surface of a tooth 20, a body 110 that protrudes a predetermined height from the body 110, A slot 120 for providing a space 130 for accommodating a wire 200 for supplying a first energy to the tooth and a slot 120 accommodated in the slot 120 to surround the outer circumferential surface of the wire 200 And a coil spring 300 for supplying a second energy to the tooth. The slot 120 may have a U-shape in which the opposite side of the lingual side of the tooth 20 is closed.

With this configuration, not only the wire 200 for supplying the first energy but also the coil spring 300 for supplying the second energy is connected to the teeth 20 displaced in the lingual direction with a force 2 energy) can be supplied to the tooth 20 and sufficient space for attaching the orthodontic bracket 100 to the teeth 20 can be provided when teeth on both sides of the tooth on the lingually displaced side are too attached, The wire 200 or the coil spring 300 is loosened to the patient when the wire 200, the coil spring 300 and the orthodontic bracket 100 are mounted on the bracket 20, There is an effect that it is possible to reduce discomfort due to a foreign object.

More specifically, the orthodontic bracket 100 of the embodiment is provided with a wire 200 for supplying a first energy to the tooth 20 and a coil spring 300 for supplying a second energy to the tooth 20 .

The conventional bracket 10 is provided to receive only the wire 200. Since the bracket 100 of the orthodontic appliance of the embodiment accommodates not only the wire 200 but also the coil spring 300, At least one of the wire 200 and the coil spring 300 may be separated from the slot 120 if the slot 120 of the embodiment is provided in a shape opposite to the lingual side like the conventional bracket 10. [ Can not be prevented.

The slot 120 of the orthodontic bracket 100 is formed in a U-shape in which the opposite side of the lingual side of the tooth 20 is closed so that the wire 200 and the coil spring 300 are inserted into the slot 120, Can be prevented.

Hereinafter, each configuration will be described.

Since the orthodontic bracket 100 of the embodiment is attached to the teeth, not only the orthodontic effect but also esthetics are required.

Accordingly, the orthodontic bracket 100 may be formed of a single crystal sapphire ceramic. Since the single crystal sapphire ceramic is excellent in transparency, it is difficult to recognize visually whether the bracket 100 is an external orthodontic bracket.

That is, since the orthodontic bracket 100 formed of a single crystal sapphire ceramic is in harmony with any tooth, it can satisfy the aesthetic requirement of the patient.

In addition, since the single crystal sapphire ceramic has excellent durability and resistance to coloring, it can be used continuously without replacing in the orthodontic step requiring long time.

Meanwhile, the slot portion 120 of the embodiment may be coated with silica to reduce frictional force. The wire 200 and the coil spring 300 are inserted into the slot 120 to apply the first energy and / or the second energy to the tooth 20, A frictional force may be generated between the slot part 120 and the slot part 120.

The energy applied by the wire 200 and the coil spring 300 to the slot 120 is transmitted to the teeth 20 to which the body 110 is attached via the body 110. [ do.

At this time, an energy greater than the bonding force between the tooth 20 and the body 110 is applied to the bar

The bracket 100 for orthodontic bracket 100 is dislodged from the tooth 20.

When the energy applied to the slot 120 by the wire 200 and the coil spring 300 is greater than the bonding force, the wire 200 is slid on the slot 120, And the slot portion 120 is coated with silica.

However, the material of the bracket 100 and the slot 120 described above is for the sake of convenience of explanation, and the user may use the orthodontic bracket 100 and / The present invention can be implemented by variously modifying the material of the slot part 120, which does not limit the scope of the present invention.

The ratio between the area of the body 110 in contact with the teeth 20 and the ratio of at least one surface of the tooth 20 on which the body 110 is disposed may be provided so as to satisfy the following relational expression.

[Relational expression]

1/15? A / B? 1/10

A: the area of the face of the body portion which is in contact with the teeth

B: area of at least one surface of the teeth

If the ratio of the area of at least one surface of the tooth to the area of the surface of the body portion that contacts the tooth is less than 1/15, the bracket 100 for orthodontic treatment is attached to the tooth 20, There is a problem that the energy generated from the wire 200 and the coil spring 300 can not be absorbed and the bracket 100 for orthodontic treatment is escaped from the tooth 20 And when the ratio of the area of at least one surface of the teeth to the area of the surface of the body 110 in contact with the teeth of the embodiment is larger than 1/10, the contact with the tooth 20 of the body 110 It is necessary to attach the orthodontic bracket 100 to the teeth 20 displaced in the lingual direction in the case where other teeth are excessively attached to both sides of the teeth 20 displaced in the lingual direction young That is because the issue.

In addition, the longitudinal length of the cross section of the body part 110 of the embodiment may be two to three times the length of the transverse part of the body part 110.

The length of the cross section of the body portion 110 of the embodiment is 2 to 3 times the length of the body portion 110 because the teeth are basically rectangular rather than square. The bracket 100 for orthodontic treatment can be attached to the teeth 20 more easily.

However, the present invention is not limited thereto. For example, the user may vary the area or the length of the surface of the body portion contacting the tooth, It shall not be limited.

The wire 200 of the embodiment is connected through at least one or more general orthodontic brackets 10 and an orthodontic bracket 100 that are fixed to the surface of the tooth 20 and each orthodontic bracket 10, The first energy is supplied to the tooth 20 on which the bracket 100 is disposed, so that the tooth 20 can be calibrated.

The wire 200 of the embodiment may be provided to have various diameters. For example, the wire 200 of the embodiment may be provided to have a numerical value of 0.007 to 0.022 inches, preferably 0.008 to 0.012 inches.

The wire 200 of the embodiment has a relatively small diameter as compared with the conventional diameter of the wire used in the related art. However, it can transmit sufficient energy to the tooth 20 to be calibrated. Since the wire 200 has a small diameter, .

However, the diameter of the wire 200 in the above-described embodiment is merely an example for convenience of explanation, and the user can vary the diameter of the wire 200 of the embodiment according to need, Nor does it limit the scope of rights of

Meanwhile, the cross section of the wire 200 of the embodiment may be circular, but it is not limited thereto and may be provided in various shapes. (For example, a polygonal cross section including a square cross section or a rectangular cross section)

On the other hand, the wire 200 of the embodiment can be made of a shape memory alloy so that it can be stored according to the shape of the tooth row in which the tooth 20 to be calibrated is arranged. For example, the wire 200 of the embodiment may be provided to include a Ni-Ti alloy harmless to the human body.

Therefore, when the wire 200 of the embodiment is attached to the tooth 20, the tooth 20 can be calibrated because the wire 200 is deformed into a shape-memorized shape.

FIG. 3 shows a coil spring mounted on the orthodontic bracket of the embodiment.

Referring to FIG. 3, the slot 120 of the orthodontic bracket 100 of the embodiment may be inclined at a predetermined angle.

More specifically, the slot 120 may be formed to have the same angle as the tilted angle of the coil spring 300 wound on the wire 200.

For example, the straight line X parallel to the lower surface of the body 110 and the slot 120 may be formed to have a predetermined angle? And an angle formed between the slot 120 and an arbitrary straight line X parallel to the lower surface of the body 110 and an angle between the angle formed by the coil spring 200 and the angle? The angle formed by the straight line X parallel to the lower surface of the body part 110 may be the same.

The slot 120 of the orthodontic bracket 100 of the embodiment may be provided to form a 50 ° to 70 ° angle with a straight line X parallel to the lower surface of the tooth 20.

If the slant angle of the coil spring 300 wound on the slot 120 is different from that of the wire 200, the second energy of the coil spring 300 is not transmitted to the slot 120 And unnecessary torque is generated.

In this case, there arises a problem that the tooth 20 displaced in the lingering direction is moved in the intended direction and in the other direction.

Accordingly, the slot 120 of the embodiment can be inclined to have the same angle as that of the coil spring 300 wound on the wire 200, thereby transmitting desired energy to the tooth 20 in a desired direction There is an effect that can be.

However, the slope of the slot 120 described above is merely an example for convenience of explanation, and the user may vary the slope of the slot 120 according to need, Not limited.

Particularly, the orthodontic bracket according to the present embodiment can be applied to most anterior correction patients, and can be applied to middle-aged men or women aged 30 to 40 years.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
