Description

Orthodontic bracket

The present invention relates to a bracket for orthodontic bracket, and more particularly, to a bracket for orthodontic bracket having a convenience of operation, a minimized foreign matter structure, and a precise orthodontic structure.

Teeth that are present in the human oral cavity may have an uneven tooth arrangement due to congenital or acquired deformities. Malocclusion refers to malocclusion, which causes functional problems such as an aesthetic problem that adversely affects appearance in human life, and a linguistic use of food intake or inaccurate pronunciation . Accordingly, orthodontic appliances have been used as dental treatment means for correcting malocclusion of teeth.

And a lingual correction method of correcting the teeth by attaching an orthodontic appliance to the surface of the tooth facing the inside of the oral cavity. In recent years, There is a high preference for lingual correction methods in which the orthodontic appliance is not exposed to the outside.

Conventional conventional orthodontic appliances used in orthodontics consist of a bracket attached to the patient's teeth and a line connecting the tooth formed in the bracket to provide a traction force to move the teeth to the calibration position. At this time, the bracket is formed with a base to be attached to the tooth surface.

Conventional orthodontic braces attach brackets one by one to the surface (tooth surface) of each dental tooth making a dentition and ligate an arch wire of rigid material to the slots formed in each bracket by ligation wire, Direction was gradually corrected over a long period of time.

However, in conventional orthodontic braces, when the wire is ligated to the slot of the bracket, the gap between the tooth surface and the wire is formed at a relatively large interval in order to secure a treatment space. In addition, a ligation wing was formed on the bracket to fix the line to the ligation line.

The bracket profile of the bracket is increased and the volume of the bracket is inevitably increased in order to secure the gap between the tooth surface and the base, the thickness of the base, and the ligation wing structure.

In addition, the undercut structure necessarily formed between the bracket and the ligation wing causes a problem that the residues of the food remain in the oral cavity, thereby deteriorating oral hygiene.

In particular, the increase in the distance between the tooth surface and the line leads to poor control of the tooth position. The orthodontic force exerted on the tooth is applied to the bracket, not the center of gravity or resistance center of the tooth. As such, the orthodontic force that does not pass through the center of resistance of the tooth inevitably generates a rotational moment. As a result of this moment of rotation, the teeth bound to the line are rotated around the bracket slot as the center of rotation. 1, there is a problem in the case where a rotation moment is generated unintentionally due to the movement of another tooth, or there is a problem in the tilting of the tooth T. Thus, a torque bend (third order the rotation of the tooth T takes place around the arc line 203 inserted in the slot of the bracket 201 as a center of rotation and as a result, The vertical height of the tip of the tooth (the cut edge, the tibia) also varies. The farther away the bracket slot from the tooth surface (the larger the bracket 201 profile), the greater the problem.

Moreover, in the case of lingual orthodontic treatment, when the stock bracket 201 is used instead of the customized bracket 201, the arc line 203, which is the center of rotation of the tooth T, is farther away from the tooth surface, The change in the height difference of the (T) cutting edge must be very large as shown in FIG.

Thus, as the distance from the tooth surface to the arc 203 increases, the amount of additional height adjustment required when adjusting the tilting of the teeth T is significantly increased.

When the distance between the tooth surface and the horizontal line 203 is increased, as the distance between the cutting tooth and the horizontal line 203 is increased, the orthodontic force becomes larger than the center point of the tooth T It is moved away from the center of resistance, so that a movement accompanied by a rotational moment rather than a pure horizontal or vertical movement is caused, and it becomes very difficult to appropriately adjust the rotational moment, thereby making it impossible to achieve ideal orthodontic correction.

Accordingly, it is desirable that the distance between the bracket 201 slot on which the wire 203 is mounted and the tooth surface is minimized when the bracket 201 is manufactured.

On the other hand, Korean Patent No. 10-1299811 discloses a bracket for non-wing teeth. In order to minimize the volume of the bracket while excluding the ligation wing structure, the bracket has a tube structure in which a slot is formed in a bracket body formed on the base, As shown in FIG.

In the case of this bracket, by removing the existing ligation wing structure, the aesthetic appearance and functional and oral hygiene aspects were improved while reducing the volume of the bracket.

However, this bracket also has a limitation in minimizing the foreign object, and the interval between the tooth surface and the line is inevitably formed at relatively large intervals, which makes it difficult to correct the orthodontic tooth.

Because basically, the bracket is equipped with a base structure for attaching to the tooth surface, and in order to pass the ligature wire or the fixing clip through the tube, it is necessary to secure a distance for securing the treatment space between the tooth surface, It is because there is not. Considering the thickness of the base, the distance between the line and the tooth surface can not but be increased.

Furthermore, since the tubes formed on the upper and lower sides of the bracket in the upper and lower regions of the line are disposed at positions corresponding to the line, the bottom surface of the slot into which the line is inserted is spaced away from the tooth surface The distance between the line and the tooth surface must be large.

As a result, the volume of the bracket is increased to minimize the foreign body sensation. As a result, an increase in the distance between the tooth surface and the row line necessarily results in difficulty in correcting the orthodontic tooth as described above.

Accordingly, an object of the present invention is to provide a bracket for orthodontic treatment which is excellent in convenience of operation and can minimize a foreign body sensation.

The present invention also provides a bracket for orthodontic treatment which can minimize the distance between a tooth surface and an arc line, thereby enabling accurate orthodontic correction.

According to the present invention, there is provided an orthodontic bracket according to the present invention, comprising: a line insertion slot attached to a tooth surface and having a line inserted along a dentition direction; and at least one vertical ligation hole intersecting with the line direction, He said; And the line inserted into the line insertion slot is located between the tooth surface and the vertical ligation hole.

Here, it is preferable that a ligation member inserted into the vertical ligation hole and preventing the escape of the line is further included.

And the side surface of the bracket facing the tooth surface is formed as an adhesive surface to be adhered to the tooth surface.

At this time, it is more preferable that the bottom surface of the line insertion slot is located at a distance within a range of 0.01 mm to 0.3 mm with respect to the tooth surface.

In addition, it is more effective that the bracket has a shape in which the cross-sectional area is reduced as the bracket is further away from the tooth surface side.

According to the present invention, there is provided an orthodontic bracket having excellent operability and minimizing a foreign body sensation.

Also, there is provided an orthodontic bracket for minimizing the distance between the tooth surface and the line and correcting the orthodontic effect.

1 is a view for explaining a problem of a conventional orthodontic bracket,
2 to 6 are views showing an embodiment of a bracket for orthodontic treatment according to the present invention,
FIG. 7 is a view for explaining generation of a tooth rotation moment in the orthodontic treatment using the bracket for orthodontic treatment according to the present invention. FIG.

As shown in FIGS. 2 to 6, the bracket 1 for orthodontic treatment according to the present invention has a shape in which the volume is reduced as much as possible and the cross-sectional area is reduced as the distance from the tooth surface side is reduced so that there is no foreign body feeling in the oral cavity.

Such a structure is intended to minimize the volume of the bracket 1 to minimize a foreign body in the oral cavity. For example, the overall shape of the bracket 1 may be a cubic shape having a hemispherical cube or a polygonal trapezoid.

On the free end side of the bracket 1, a row insertion slot 10 opened to the opposite side of the tooth surface is formed in the dentition direction. The line insertion slot 10 has a structure in which an arc line 50 for providing a tooth traction force is inserted. In order to minimize the distance between the arc line 50 and the tooth surface, Lt; / RTI >

Specifically, it is preferable that the bottom surface of the wire insertion slot 10 is located at a distance within a range of 0.01 mm to 0.3 mm with respect to the tooth surface.

The proximity distance between this tooth surface and the bottom surface of the row insertion slot 10 results in the row 50 being inserted into the row insertion slot 10 to be as close as possible to the tooth surface.

As shown in FIG. 7, when the tooth 50 rotates about the arbor 50, a rotation moment is applied to the bracket 1 as in the prior art, The distance from the tooth surface to the line 50 is minimized to minimize the height difference change ('b'), and the amount of additional height adjustment is greatly reduced when adjusting the inclination of the lingual side of the tooth.

As a result, even when the tooth is moved horizontally and vertically, the distance between the tooth surface or the cutting edge and the line 50 is minimized, so that the correcting force is applied close to the center of the teeth or the center of the tooth, , Even if the movement accompanied by the rotational moment is caused, it is affected by the minimum rotational moment, so that the ideal orthodontic treatment is possible.

For example, in the conventional technique in which the rotational moment of the teeth is largely generated, as described above, the difference in the cutting height of the tooth is largely generated, and serious problems that the root is not aligned can occur. In other words, even if the teeth are aligned, root alignment is not performed and fundamental tooth correction is not performed.

On the other hand, as in the present invention, when the line 50 is close to the tooth surface, even when a rotational moment of the tooth occurs, the minimum rotational moment is generated and the difference in the cutting height of the tooth is minimized. Thereby, the alignment of the roots is also aligned as close as possible to the position corresponding to the root position of the teeth after the ideal correction, so that the alignment of the teeth takes place together with the alignment of the roots. Thereby, an ideal tooth correction is performed.

On the other hand, the line 50 may have a curvature and / or a straight section corresponding to a curvature and / or a straight line of the dentition, wherein the line insertion slot 10 has a curvature and / Curvature and / or straight line so that the line 50 can be inserted completely in close contact with the line insertion slot 10. This allows accurate orthodontic correction. At this time, the line 50 and the line insertion slot 10 may have only a curvature section in both the lingual side and the lingual side, depending on the tooth structure of the patient's oral cavity.

A side surface of the bracket 1 facing the tooth surface is not formed with a separate adhesive surface 30 structure in order to adhere the bracket 1 to the tooth surface and the side surface facing the tooth surface of the bracket 1 is directly bonded to the tooth surface (30). This is to maximize the reduction of the volume of the bracket 1 and the reduction of the distance between the tooth surface and the line 50.

On the other hand, a vertical ligation hole 20 is formed in the bracket 1 as a structure for fixing the line 50 to the bracket 1.

The vertical ligation holes 20 are formed in at least one direction perpendicular to the direction of the line 50. It is effective that a pair of vertical ligation holes 20 are formed in each of the brackets 1. At this time, the position of the vertical ligation hole 20 is formed in the free end region of the bracket 1 in a range in which an arc line 50 inserted into the arc insertion slot 10 is positioned between the tooth surface and the vertical ligation hole 20 .

In this vertical coupling groove, a wire-like ligature line (not shown) is passed through to connect the arc line 50 and the bracket 1 to fix the arc line 50 to the bracket 1.

3 to 6, a separate ligation member 40 is inserted into the vertical ligation hole 20 to fix the ligation line 50 to the bracket 1 by using the vertical ligation hole 20 or the vertical ligation hole 20. [ . 3, the length of the ligation member 40 is such that the outer diameter of the ligation member 40 can be firmly inserted into the vertical ligation hole 20, So that the foreign body sensation in the oral cavity can be minimized.

Of course, the ligation member 40 may have a length that protrudes from the vertical ligation hole 20, as shown in Figs. 4 to 6, in which both ends of the ligation member 40 are bent, Can be prevented.

Although not shown, the wire 50 and the bracket 1 and the ligature member 40 may be ligated to each other by using a ligature line (not shown) together with the use of the ligature member 40. [

Here, the shape of the ligature member 40 may be a single bar shape inserted into each of the vertical ligation holes 20, or may be in the form of an inverted U shape as shown in FIG.

The process of performing the orthodontic bracket 1 according to the present invention having such a configuration will now be briefly described.

First, an adhesive material is applied to the adhesive surface 30 of the bracket 1 having the minimum volume and / or the corresponding tooth surface, and the bracket 1 is attached to the tooth surface of each tooth to be subjected to orthodontic treatment.

Then, the wire 50 is inserted into the wire insertion slot 10 of each bracket 1.

The ligation wire (not shown) and / or the ligation member 40 may be inserted into the vertical ligation hole 20 so that the bracket 1 and the line 50 can be ligated to each other as described above.

At this time, in the process of inserting the ligature line (not shown) and / or the ligature member 40 into the vertical ligature hole 20, the vertical ligature hole 20 is formed at a position farther than the angular line 50 with respect to the tooth surface A sufficient treatment space can be ensured and the bracket 1 and the arterial line 50 can be ligated very easily using a ligating line (not shown) and / or a ligating member 40 without space limitation.

After the attachment of the bracket 1 and the ligation of the bracket 1 and the arterial line 50 using the vertical ligation hole 20 and the ligation of the bracket 1 and the arterial line 50 and the ligation member 40 are completed, The line 50 is connected during fixation means (not shown), such as a pre-fixed fixation plate in the oral cavity, to provide a traction on the teeth.

As described above, the orthodontic bracket 1 according to the present invention does not have a separate attachment structure, and the tooth surface side of the bracket 1 is formed as the bonding surface 30, and by the position of the vertical ligation hole 20, It is necessary to increase the distance between the line 50 and the tooth surface in order to secure the treatment space by making the line 50 inserted into the slot 10 be located as close as possible to the tooth surface between the tooth surface and the vertical ligation hole 20. [ Can be reduced to a minimum distance.

Thus, the volume of the entire bracket 1 can be reduced to minimize the foreign body sensation in the oral cavity.

In addition, since the ligation wire (not shown) or the ligation member 40 is inserted into the vertical ligation hole 20 spaced from the tooth surface from the tooth line 50, the convenience of the procedure is remarkably improved even in a narrow space in the oral cavity .

In particular, the distance between the tooth surface and the line 50 is minimized, so that accurate orthodontic correction is achieved, as described above.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, there is provided an orthodontic bracket having excellent operability and minimizing a foreign body sensation.

Also, there is provided an orthodontic bracket for minimizing the distance between the tooth surface and the line and correcting the orthodontic effect.
