The present invention relates to an orthodontic fixing device, and more particularly, to an orthodontic fixing device having an improved structure for fixing an orthodontic appliance for orthodontic treatment.

Orthodontics are generally achieved by combining orthodontic instruments that can generate traction between the orthodontic teeth and the fixture. In this case, in order for the orthodontic appliance installed between the corrected tooth and the fixing device to continuously generate the traction force toward the fixing device by the principle of action and reaction, a fixing device capable of continuously maintaining a strong fixing force is required. As such a fixing device, a method of installing a fixing device directly on the bone of the gum bone or the palate has recently been proposed.

Korean Utility Model Registration No. 196064 describes a "orthodontic appliance through cortical bone cutting" that cuts the soft tissues of the palate and inserts the fixation of the cruciate fixture or fixes the piece to the bone in the screw hole to the bone. However, since the orthodontic appliance needs to be incised after the incision of the soft tissue covering the bone, the procedure of implantation and removal is complicated, and the portion protruding to the outside of the fixing device to change the force system during orthodontic treatment When adjusting the shape of the hassle to remove all the pieces or screws inserted into the bone to remove the fixing device.

In addition, in the above technique, when the piece or screw is placed in the oral cavity, the shape of the structure such as the palate in the oral cavity is not flat and is curved in an annular shape so that it is not easy to precisely insert the screw in the desired position and direction so that the screw is placed out of the set position. In this case, the bone plate is unstable because it is not in close contact with the bone surface, so there is a difficulty in the procedure, such as a need for re-treatment.

Korean Utility Model Registration No. 353672 describes a "orthodontic fixing device" that solves the above problem. Looking at the technical content with reference to Figure 1 as follows. As shown in FIG. 1, the conventional fixing device 100 includes a pair of fixing units 110 fixed through a soft tissue to bone, and two through holes for connecting and fixing a pair of fixing units 110. The balls 121 and 122 are formed of a plate 120 formed to be spaced apart from each other. The fixing unit 110 is composed of a screw 111 formed with various types of screw lines and cutouts on the outer circumferential surface, and a bolt 112 coupled to the upper surface of the screw 111. In addition, the plate 110 includes two through-holes 121 and 122 having a size to which the lower end of the bolt 112 can be fitted to be fixed to the upper surface of the screw 111 through the bolt 112. At this time, one through hole 122 is configured in the form of a long hole is configured to be different from the coupling position of the bolt (112).

Therefore, the above technique has the advantage that it is possible to fix while preventing the damage to the skin tissue through the deformation of the screw, even if the screw is fixed to the bone out of the set position through the plate having a long hole has the advantage that the bolt can be adjusted.

However, the prior art has the following problems when considering the orthodontic work. That is, a conventional orthodontic operation has a process of placing the screw in the bone, a fixed plate to the screw after a certain period of time, and connecting the orthodontic appliance such as steel wire to the plate. However, in the prior art, in fixing the plate to the screw, it is necessary to tighten and fix the bolt, and if the bolt is loosened and dropped, there is a risk of falling into the airway.

Therefore, in the prior art, when the bolt is tightened or loosened to attach or detach the plate, a rotational force is applied to the screw in which the osteointegration starts after a certain period of time, thereby exerting an impact between the bone and the screw. Therefore, the bone fusion between the screw and the bone is broken, and once the bone fusion is broken, the bone at the interface between the bone and the screw is broken, which causes the problem that the screw is shaken and dropped.

In addition, the conventional method requires inserting and fixing two small bolts to fix the plate to the two screws, which is not only easy to operate in the oral cavity of two small bolts, There is a drawback to the risk of going to.

Therefore, the present invention has been made in order to solve the problems of the prior art as described above, bone fusion by limiting the force such as rotational force generated by fixing the plate to the fixed unit placed in the bone hardly acts on the fixed unit It is an object of the present invention to provide an orthodontic fixation device that minimizes the impact between the fixing unit and the bone.
