Description

Orthodontic bracket easy to alignment}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an orthodontic bracket, and more particularly, to an orthodontic bracket for enhancing a bonding force between an adhesive and a contact protrusion.

In general, the orthodontic work is the work of correcting the dentition. The orthodontic method is to fix the orthodontic bracket to the inside of the tooth and to make contact with the tongue, and to attach the bracket of the orthodontic brace to the outside of the tooth, And an internal calibration method that installs the sensor.

When performing the orthodontic treatment with the above internal calibration method, the bracket should be attached to the tooth without any dislodgement during the period of orthodontic correction, and should not damage the tooth surface when it is desorbed after completing the orthodontic treatment.

Here, a conventional bracket using an inner calibrating method is disclosed in, for example, Korean Patent Registration No. 0977708 (titled, orthodontic bracket). To briefly describe this bracket, a bracket shown in Figs. 1A and 1B A plurality of wings 11 formed on one side of the body 10 and a slot 12 formed between the wings 11 and fitted with dentition arch wires (not shown) An adhesive surface 13 which is one surface of the other side of the body 10 and a plurality of protrusions 14 protruding from the adhesive surface 13. [ Further, the dimples 15 are formed on any of the wings 11 so as to recognize which tooth of the bracket is used.

In order to perform orthodontic correction using such an orthodontic bracket, the adhesive is first applied to a predetermined portion of the tooth surface to be calibrated, and then the adhesive surface 13 of the body 10 is coated with an adhesive before the adhesive is completely solidified And aligns the position of the body 10 so that the wire is easily fitted into the slot 12 and waits until the adhesive is completely solidified. Thereafter, when the adhesive is completely solidified, the wire is inserted into the slot 12, and both ends of the wire are supported and fixed by a supporting member fixed to a molar or the like, thereby completing the installation of the orthodontic bracket.

However, since the projections 14 are formed in a relief shape, it is very difficult to apply a predetermined amount of the adhesive. This is because if the amount of the adhesive to be applied to the tooth is small, only a part of the adhesive surface is adhered to the tooth, so that the adhesive force of the adhesive is lowered, so that the bracket can be detached from the tooth. If the amount of the adhesive is excessive, There is a problem that it is difficult to remove the bracket from the teeth in the future because of the strong adhesiveness of the adhesive.

KR0977708 10

It is an object of the present invention to provide an orthodontic bracket so that the contact protrusion of the adhesive surface is engraved and the adhesive is received in a bracket rather than a tooth in a fixed amount to improve the adhesive force between the adhesive and the contact protrusion.

In order to achieve the above object, the present invention provides a bracket for orthodontic brace comprising a binding portion having a plurality of wings on one side of a body and a bonding portion having a bonding surface formed on the other side of the body, , And the adhesive portion includes protrusions protruding from the adhesive surface and having a side section length shorter than that of the upper portion.

Here, the adhering portion may further include a first receiving groove formed at both sides of the bonding surface which is a lower surface of the body, the first receiving groove being formed at an engraved angle, and the protrusion may include a first protrusion, a second protrusion, .

At this time, the first projection may be a hexagonal columnar shape that is rectangular in plan and a side is inclined by an undercut, or the upper part of the hexagonal column is heated by heat and then pressed downward to form a curved surface. And a shape including a lower portion inclined from a vertical direction or a vertical direction while continuing from the upper portion.

Further, the first projections are arranged in one row in each of the first receiving grooves.

The first protrusions are formed by being inclined at an angle with respect to the horizontal, and the first protrusions formed in the pair of first receiving grooves formed on both sides of the contact surface are symmetrically arranged.

The second projections and the third projections are cylindrically shaped, and the diameter of the second projections is smaller than the diameter of the third projections.

The second projection is disposed on a short side of the first projection, and the third projection is disposed on a long side of the first projection.

Further, the adhesive is densely packed on the long side of the first projection, and the interval between the first projection and the second projection is larger than the interval between the first projection and the third projection so as to flow through the short side.

Here, the bonding portion is further provided with a second receiving groove formed in the center of the bonding surface with a width and a length shorter than the first receiving groove, and a fourth projection formed in the second receiving groove.

At this time, the depth of the second receiving groove is shallower than the depth of the first receiving groove.

A third receiving groove is further formed in the second receiving groove at a negative angle, and a fourth projection is formed in the third receiving groove.

The third receiving grooves are elliptical and formed in a plurality of rows, and the fourth protrusions 380 are formed in the respective third receiving grooves 370.

Further, the third receiving grooves are symmetrically adjacent to each other.

It is further characterized in that the adhesive portion further comprises an identification code, which is drawn on a part of the adhesive surface to identify whether the bracket is attached to the maxillary or mandibular teeth in the oral structure.

On the other hand, the binding portion includes a second slot formed between the wings for aligning with a reference line indicated on the teeth.

And the second slot is coated with a pigment so that the second slot is recognized as an alignment line.

The second slot intersects the first slot formed between the wings so as to fit the arch wire, and is formed up to or at both ends of the body.

The binding portion may further include an alignment groove formed at one end of the second slot or positioned on an extension line and recessed at one end of the plane-shaped body.

Further, the binding unit may further include a ball hook formed on one of the wings, and a dimple formed on one of the wing surfaces.

In addition, the binding unit includes a holding jaw that is connected to the binding unit at a right angle or a curved surface while a width of the adhesive unit is wider than that of the binding unit to hold the body.

Further, the sides of the wings on which the gripping jaws are formed form the same plane.

As described above, according to the present invention, by forming the second slot at a different angle from the first slot in which the arch wire is inserted into the body of the bracket and forming the alignment groove at one side of the second slot, It is possible to attach the bracket to the teeth at an accurate position by aligning the alignment grooves and the baseline indicated on the teeth exactly.

In addition, there is an effect that the second slot can be more easily aligned with the baseline of the tooth by applying pigment visually recognizable.

In addition, since a step for gripping is formed on the corresponding both side surfaces of the body, the inconvenience that the tweezers come in contact with the teeth when the body is gripped by a tool such as a tweezers is prevented, .

In addition, since the receiving grooves are formed in the engaging surface of the body at a negative angle and a certain amount of adhesive is accommodated in the receiving grooves in which the projections are formed, it is possible to provide an appropriate adhesive force for attaching and detaching the brackets, It is effective.

Further, since the first projection is formed so as to form an undercut with respect to the bottom surface of the receiving groove, there is an effect that the adhesive contained in the receiving groove is more strongly adhered to the projection.

Further, when a second projection having a small diameter and a large diameter is formed on the short side and the long side of the first projection so that the adhesive penetrates the undercut of the first projection, the curved surface of the second projection projects to the undercut portion of the first projection The adjacent distance between the long surface of the first projection and the second projection having the large diameter is shorter than the short distance between the short surface of the first projection and the second projection having the small diameter So that the adhesive is uniformly penetrated to the respective surfaces of the first projections.

The center protrusion of the contact surface formed in the same direction as the second slot is formed in a double lock shape and its area is smaller than that of the protrusions on both sides to strengthen the adhesive force between the adhesive and the central protrusion, When the external force is applied to remove the bracket from the tooth, the bracket can be easily removed from the central portion of the bracket, so that the bracket can be removed more easily.

2, the bracket for orthodontic treatment according to the present invention includes a body 100, a binding part 200 formed on the upper part of the body 100, and a bonding part 300 bonded to the teeth.

The binding unit 200 includes a plurality of wings 210 divided into a plurality of zones and a ball hook 220 formed on the surface of one of the wings 210 and a plurality of wings 210 formed between the dimples 230 and the wings 210. [ A second slot 250 formed between the wings 210 orthogonal to the first slot 240 and an alignment groove 260 formed at one side of the second slot 250, And a gripping protrusion 270 formed on both sides of the body 100 so as to be parallel to the second slot 250.

2, the wings 210 are spaced apart from each other at approximately four corners of the body 100, and the first slots 240 and the second slots 240 are formed between the wings 210 at substantially mutually orthogonal angles. A slot 250 is formed. In addition, a ball hook 220 is formed on one of the wings 210, and a dimple 230 is formed on a surface of the wing 210 that is the same as or different from the wing 210. In the dimples 230, colors are painted to distinguish brackets corresponding to positions of individual teeth.

 Of course, the first slot 240 and the second slot 250 may intersect but not necessarily be perpendicular to each other. An arch wire inserted into the first slot 240 via these wings 210 may be connected to an O- And is fixed through a separate member, including.

Here, the ball hook 220 is for providing an assisting force to a plurality of brackets attached to the teeth through an arch wire. As an example, the ball hook 220 may be provided on the auxiliary wire to provide auxiliary assisting force different from the binding force provided by the arch wire. One end of the auxiliary wire is engaged and fastened so that the bracket can be pulled.

The dimples 230 are recessed in the surface of any one of the wings 210 to indicate a use position so that the operator can recognize which bracket is used. And may be formed into various shapes.

2 and 3, the first slot 240 is a portion where the arch wire is inserted, and the arch wire inserted in the first slot 240 is tightened to press the bracket toward the teeth.

The second slot 250 is also formed between the wings 210 so as to intersect the first slot 240. The second slot 250 is formed to align the bracket with the correct position of the teeth. It is preferable to apply a pigment of a color which can be visually recognized to be recognized as an alignment line. Accordingly, when the bracket is attached to the tooth, the reference line indicated on the tooth aligns with the alignment line indicated on the second slot 250. Here, the second slot 250 may be formed to both ends of the body 100 or only a part of the body 100.

Also, the alignment groove 260 is also a portion formed to align the bracket with the correct position of the tooth, like the second slot 250, and the tip of the body 100 on one side of the second slot 250, . Accordingly, the alignment line of the second slot 250 is aligned with the alignment groove 260 with respect to the reference line indicated on the tooth, thereby aligning the bracket with the correct position of the tooth.

4 and 5, when the body 100 is gripped by a tool such as a tweezer or the like, the holding jaw 270 is formed as a portion formed to facilitate gripping of the body 100, And the connection portions are formed at right angles or curved surfaces in a state where the width of the adhesive portion 300 is wider. Here, FIG. 4 is a view of the angle viewed from a slightly higher angle than the front, and FIG.

These gripping jaws 270 are respectively formed at corresponding portions and the sides of the binding portion 200 of the gripping jaws 270, i.e., the wings 210, have the same plane. It is most preferable to grip the side portion of the wing 210 with a tool. The width of the bonding portion 300 is wider than the width of the binding portion 200 so that a tool such as a tweezers does not touch the teeth when the side surface of the wing 210 is gripped by the holding jaws 270.

2 and 6, the adhesive 300 refers to a lower portion of the body 100 for convenience of description and includes an adhesive surface 310 as a lower surface of the body 100, A first protrusion 330 protruding from the first receiving groove 320, a second protrusion 340 and a third protrusion 350 protruding from the first receiving groove 320, A plurality of third receiving grooves 370 formed intaglio in the second receiving grooves 360 and a plurality of third receiving grooves 370 formed in the third receiving grooves 370 380).

First, the adhesive surface 310 is a surface that contacts the tooth together with a plurality of protrusions. The adhesive surface 310 is formed with a plurality of receiving grooves for receiving an adhesive, and a plurality of protrusions are formed in the receiving grooves 310 A detailed description of these receiving grooves and projections will be given later.

An identification code 280 is written on the surface or is etched to identify the brackets that attach to the maxillary and mandibular teeth on a portion of the adhesive surface 310. As an example of such identification code 280, "C" is plotted on the surface, and as "C" is correctly positioned or reversed, it is identified whether the bracket is in the correct upper and lower positions. This identification code 280 is used to identify the bracket with the dimple 230 when the brackets are intermingled with one another.

Further, the adhesive surface 310 is formed to have a curved surface similar to the horizontal curved surface of the teeth. It is a matter of course that the receiving grooves and the protrusions are formed at the same or lower height than the plane of the adhesive surface 310 forming the curved surface, and the repetition will be briefly described later, if necessary.

As shown in FIG. 6, the first receiving groove 320 is formed at a predetermined depth on both sides of the bonding surface 310, and a predetermined amount of adhesive is received in the first receiving groove 320. Here, the bottom surface of the first receiving groove 320 may be inclined at a predetermined angle in one direction with respect to the horizontal direction, so that the adhesive flows smoothly through the inclination of the bottom surface, In detail, the adhesive is supplied to a relatively high bottom surface area, and the adhesive flows naturally to the bottom surface side so that the adhesive is received in the first receiving groove 320.

In addition, a vent hole may be formed in the first receiving groove 320 to communicate with the outside at a portion where a relatively low bottom surface is formed. While the adhesive is received in the first receiving groove 320 through the vent hole So that possible bubbles are discharged to the outside. At this time, a separate stopper is provided. When the adhesive is supplied, the vent hole is opened to allow the bubble to be discharged to the outside, and when the supply of the adhesive is completed, the vent hole is closed with the stopper.

That is, when the adhesive is supplied to the entire area of the first receiving groove 320 as in the prior art, the inclined bottom surface and the vent hole of the first receiving groove 320 may generate bubbles in the first receiving groove 320 The adhesive is supplied to the first receiving groove 320 so as to flow from the relatively high bottom surface side to the low bottom surface side, and the bubbles that can be generated at this time are pushed, As shown in FIG.

6 to 7B, the first protrusions 330 are formed in a single row in the first receiving groove 320 and have a hexagonal shape with a substantially rectangular cross section. The first protrusions 330 are formed in the first receiving groove 320, And a bottom surface of the bottom plate 331 is formed with an undercut 331 at an acute angle. The adhesive flows in a wedge shape between the first protrusions 330 and the second and third protrusions 330 and 340 through the undercut 331.

In addition, the undercut 331 can be machined to the second and third protrusions 330 and 340 in addition to the first protrusion 330. If only one protrusion is machined, the mold can be easily manufactured. Since the first protrusions 330 have a rectangular parallelepiped shape, the first protrusions 330 are stronger in bonding force than in the case where one or more sides are formed into curved surfaces. This is due to the linkage between the space formed by the undercut 331 and the second and third projections 340 and 350 described later. Since the second and third protrusions 340 and 350 are disposed on four sides of the first protrusion 330, when the adhesive flows between the first and second protrusions 330 and 340 or the first and third protrusions 330 and 350, A wedge-shaped adhesive flow is generated on all four sides of the guide plate 330, so that the fluidity at the area is strong, thereby improving density, compactness, and adhesion.

The first protrusions 330 are formed to be inclined obliquely with respect to the horizontal in a planar shape and the first protrusions 330 formed in a pair of first receiving grooves 320 formed on both sides of the contact surface are arranged to be symmetrical do.

9, the first projection 330 is formed so as to have an upper portion having a convexly curved upper surface and a vertical or inclined lower portion in a substantially hexahedral column. At this time, when the lower part is inclined, the lower width is shorter than the upper part. 8 and 9 illustrate the structure between the first protrusion 330 and the third protrusion 350 although the first and second protrusions 330 and 340 are shown.

The second protrusions 340 and the third protrusions 350 are formed in the first receiving grooves 320 and are arranged on the slopes of the first protrusions 330 having a substantially quadrangular shape. Like the first protrusions 330, the second and third protrusions 340 and 350 may form a space through the undercut 331 having an acute angle with the bottom surface of the first receiving recess 320, The same or enhanced action effects can be obtained. At this time, the pair of second projections 340 are formed at positions corresponding to each other and adjacent to the short side of the first projections 330, and the pair of third projections 350 are positioned at mutually corresponding positions 1 protrusion 330 is formed to be continuous with the long side. The diameter of the second protrusion 340 is smaller than the diameter of the third protrusion 350.

The distance between the second projection 340 and the first projection 330 is larger than the distance between the third projection 350 and the first projection 330 and the distance between the second projection 340 and the first projection 330 is larger than the distance between the third projection 350 and the first projection 330, Is formed to be smaller than the diameter of the projection 350. This is because while the adhesive is supplied to the first receiving groove 320, the flow rate of the adhesive is slowed on the side of the longer length of the shorter side of the first projection 330 So that the flow speed of the first protrusion 330 is relatively faster than the length of the long side of the first protrusion 330 to increase the supply speed of the adhesive.

6 and 7A, the second receiving groove 360 is formed so as to be shallower than the depth of the first receiving groove 320 at the central portion of the adhesive surface 310 so that the adhesive is accommodated in the second receiving groove 360. At this time, (360) is formed to be smaller than the width and length of the first receiving groove (320), so that the attachment force of the bracket is lower than that of the first receiving groove (320) when the bracket is attached to the teeth.

Accordingly, when the bracket is detached from the teeth, the central portion of the adhesive surface 310 having a low adhesive force is first torn away so that both side portions can be easily detached.

The third receiving grooves 370 are formed in a plurality of rows in the second receiving grooves 360 and are formed deeper than the second receiving grooves 360. The third receiving grooves 370 are planar, To form an approximately elliptical shape. In addition, the mutually adjacent third receiving grooves 370 are each formed symmetrically.

The fourth protrusion 380 is formed in a columnar shape with a substantially circular cross section and is formed at a central portion of the third accommodating groove 370 while being higher than the depth of the third accommodating groove 370 and the height of the second accommodating groove 360 And is equal to or lower than the plane of the adhesive surface 310, which is the curved surface. Here, only the fourth protrusion 380 may be formed in the second receiving groove 360 with the third receiving groove 370 removed.

The first, second, third, and fourth protrusions 330, 340, 350, and 380 may be formed directly on the bonding surface 310 while the first, second, and third receiving grooves 320, 360, The first, second, third, and fourth protrusions 330, 340, 250, and 380 may be formed in the receiving groove of the first, second,

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
