The description will be omitted.

1 is a perspective view illustrating an orthodontic bracket 100 according to an embodiment of the present invention. 2 and 3 are side views illustrating the orthodontic bracket 100 shown in Fig. 1, respectively. Fig. 2 shows a state in which the wire w is inserted into the latching groove 146 of the latching protrusion 140 3 illustrates a state in which the wire w is inserted into the seating groove 118 of the base 110. As shown in Fig. 4 is a front view illustrating the orthodontic bracket 100 illustrated in Fig.

1 to 4, an orthodontic bracket 100 according to an embodiment of the present invention includes a base 110 attached to teeth, an attachment front surface 122 corresponding to one surface of the base 110, And a locking protrusion 140 spaced apart from the locking protrusion 140 by a predetermined distance.

The orthodontic bracket 100 according to the present embodiment is characterized in that a base 110 and a locking protrusion 140 are integrally formed. The base 110 and the latching protrusions 140 may be integrally formed by injection molding, sintering, or the like. The integrated structure of the bracket 100 facilitates the manufacture and reduces the manufacturing cost .

The base 110 is attached and fixed to the front or rear surface of the tooth. The orthodontic bracket 100 according to the present embodiment includes a base 110 of a shape. Of course, the base 110 may have various shapes without being limited thereto, and the present invention is not limited by the shape of the base 110. The base 110 includes an attachment portion 112 attached to a tooth and a protrusion 130 protruding vertically at an end of the attachment portion 112. [

The attachment portion 112 has a generally rectangular parallelepiped shape and includes a lower attachment surface 114 attached to the teeth, a pair of attachment side surfaces 116 formed parallel to each other, an attachment front surface 114 corresponding to the front surface of the attachment portion 112, (Not shown). Each corner of the attachment portion 112 may have a round shape.

The lower attachment surface 114 may have a planar shape, but may have a curved shape depending on the shape of the tooth to be attached. Further, the lower attachment surface 114 may be provided with a projection (not shown) having various shapes and sizes to facilitate attachment to the teeth.

The attachment side surface 116 corresponds to both sides of the lower attachment surface 114, so that the attachment portion 112 has a constant thickness. At the end of the attachment side surface 116, a seating groove 118 having a depressed shape is formed. The seating grooves 118 are formed at the same positions on a pair of mounting side surfaces 116 that are parallel to each other, and correspond to the grooves into which the wires w can be hooked, as illustrated in Fig. Thus, the wire w is caught by the step 120 of the seating groove 118, so that the wire w is not separated downward.

The length a of the seating groove 118 may be equal to or slightly greater than the minimum diameter of the wire w. Therefore, even if a wire w having various diameters is used, it can be caught in the seating groove 118.

The attachment front face 122 corresponds to a face exposed to the outside as a face opposed to the lower attachment face 114. At one end of the attachment front face 122, a protrusion 130 is vertically protruded. On the upper surface of the attachment front surface 122, a front groove 124 having a generally concave shape is formed.

The front grooves 124 correspond to the grooves formed somewhat lower than the opposite end portions of the attachment portion 112. The front groove 124 provides a space necessary for removing the wire w from the bracket 100 so that it is easy to hook and pull the wire w to and from the bracket 100. [

The projecting portion 130 corresponds to a portion that vertically protrudes from the end of the attaching portion 112 and connects the attaching portion 112 and the engaging protrusion 140 with each other. 2 to 3, in the bracket 100 according to the present embodiment, the attachment portion 112 and the protrusion 130 are vertically connected to each other, but the bracket according to another embodiment may have a curved shape or a predetermined inclination angle Of course. The protruding portion 130 includes an inner surface 132 and a pair of protruding curved surfaces 134 symmetrically formed on the right and left sides of the inner surface 132 and a protruding front surface 136 corresponding to the upper surface of the protruded portion 130. [ .

The inner side surface 132 has a flat shape as a surface corresponding to a portion covered by the engaging projection 140 in the projecting portion 130. On the left and right sides of the inner side surface 132, protruding curved surfaces 134 are formed symmetrically. 2 to 3, a wire w may be caught on the inner side surface 132, thereby preventing the wire w from being separated upward from the bracket 100. Referring to FIG. 4, a locking protrusion 140 is extended from the inner side surface 132.

The protruding curved surface 134 may be symmetrically formed as a pair of curved surfaces that are formed to be inclined upward in the direction of the right and left ends of the bracket 100 from the engaging projection 140. By forming the protruding curved surfaces 134 on the right and left sides of the locking protrusion 140, it is possible to prevent the wire w from being detached from the locking protrusion 140, .

The protruding front surface 136 of the protruding portion 130 is a surface parallel to the attaching front surface 122 of the attaching portion 112 and forms the same plane as the protruding front surface 142 of the engaging protrusion 140. [ Therefore, the height of the protruding front surface 136 determines the height of the latching protrusion 140. [ Of course, the height of the protruding front surface 136 and the protruding front surface 142 of the bracket according to another embodiment may be different.

The locking protrusions 140 are vertically extended from the ends of the protrusions 130 and are spaced apart from each other at an attaching front surface 122 corresponding to one surface of the base 110 and opposed to the attaching front surface 122. Therefore, the latching protrusion 140 corresponds to the portion where the wire w is caught, and prevents the wire w from deviating upward.

The engaging protrusion 140 has a protrusion front surface 142, a protrusion inner surface 144, a protrusion side surface 148, and a protrusion bottom surface 150.

The engaging protrusion 140 has a protruding front surface 142 of an isosceles trapezoidal shape. The protrusion front surface 142 corresponds to the front surface of the locking protrusion 140 and may be formed to be smaller than the entire width of the bracket 100. Thus, the engaging protrusion 140 has a width smaller than the entire width of the bracket 100. [ Of course, the locking protrusion 140 may have the same width as the entire width of the bracket 100.

The engaging protrusion 140 has a protruding lower surface 150 and a pair of protruding side surfaces 148 and has a constant thickness.

The projection inner side surface 144 corresponds to a surface facing the projection front surface 142 and a surface contacting the wire w. The projection inner side surface 144 is provided with an engaging groove 146 formed at an engraved angle. Referring to FIG. 2, a wire w may be inserted into the latch groove 146, thereby preventing the wire w from being separated upward.

The distance b between the engaging projections 140 with respect to the bottom surface of the front groove 124 may be somewhat larger than the maximum diameter of the wire w. This allows the wire w to be hooked on the bracket 100 by pulling the wire w having various diameters into the space between the inner side surface 144 and the attachment front surface 122 or pulling the wire w I can take it out.

4, the distance c between the side end portion of the engaging projection 140 and the side end portion of the attachment portion 112 can be made larger than the maximum diameter of the wire w, So that it can be easily engaged or disengaged from the locking projection 140.

The latching protrusion 140 having the latching groove 146 can be formed using a slide core and / or a deformed core die when a mold (not shown) is manufactured.

In the orthodontic bracket 100 according to the present embodiment, the latching groove 146 is formed in the inner side surface (the inner surface 144 of the latching projection) of the latching protrusion 140 in a concave manner, Since the engaging groove 118 of the engraved shape is formed in the groove 110, when the wire w is separated, the curve of the wire w becomes free. Therefore, the bracket 100 for orthodontic treatment according to the present embodiment has the advantage of being easy to use because it can be attached and detached with a slight elastic deformation of the wire w and can be adjusted variably.

In addition, since the base 110 and the locking protrusion 140 are formed integrally with the orthodontic bracket 100 according to the present embodiment, the cleaning is easy and the assembling process and the post-process are simplified, thereby reducing the manufacturing cost .

5 and 6 are perspective views illustrating a state in which a wire is taken out from a bracket according to an embodiment of the present invention.

5, when the end portion of the wire w is pulled downward, a part of the wire w (indicated by a dotted circle) is bent so as to escape through the lower space of the latching protrusion 140. Referring to FIG. 6, the end of the wire w can be pulled up and pulled forward (in the direction of the arrow) to pull the wire out of the latching protrusion 140.

7 is a view illustrating a use state of the bracket 100 according to an embodiment of the present invention.

Referring to FIG. 7, one bracket 100 is fixed to the front surface of each tooth t. It can be seen that one wire (w) is caught in the latching protrusion (140) of the plurality of brackets (100). Since the center tooth t is positioned lower than the adjacent teeth t, the wire w can be pulled in the desired direction by hanging the bracket 100.

If the protruded curved surface 134 is formed in a straight shape without forming the curved surface 134, a problem arises in that the wire is subjected to a force to move it downward. The bracket 100 according to the present embodiment solves such a problem by forming the protruding curved surfaces 134 on both left and right sides of the locking protrusion 140. The protruding curved surfaces 134 are formed on both left and right sides of the locking protrusions 140 of the bracket 100 so that the wires w can be brought into close contact with the protruding curved surfaces 134 to be well seated.

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, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
