The present invention relates to an implant and an orthodontic appliance using the same, and more particularly, to an implant and an orthodontic appliance using the improved head portion.

Typically, orthodontics are made by fixing the bracket to the surface of an individual tooth with an adhesive, passing the wire through the bracket, and then using the restoring force caused by the elasticity of the wire to the outside, such as pressing, pulling, and non-gap force on the tooth. This is accomplished by applying individual force (hereinafter abbreviated as orthodontic force) to move the individual teeth relatively.

In order to provide orthodontic force to the teeth as described above, it is proposed to use the external oral fixation or install the fixing device directly on the bone of the gum bone or palate and then use it.

Meanwhile, implants for orthodontics are disclosed in US Pat. Nos. US2002182560, US2004152935, and WO 0203880. In particular, US Patent 2004152035 discloses a fixing means having at least one inlet for fixing the tension or rotation member in the head portion.

In addition, US Patent 5,921,774 (Japanese Patent Laid-Open No. 10-99347) discloses orthodontic support structures. The disclosed orthodontic support structure includes an implant portion (transplant unit) for implanting into a desired portion in the jawbone and an exposed portion (bonding unit) attached to the implant head. The implant is measured at 2 mm at its maximum point in the diameter of its horizontal cross section and the exposed site includes an arm with hooks (tightening) extending into the oral cavity.

Korean Utility Model Registration No. 196064 describes a "orthodontic appliance through cortical bone cutting" that cuts the soft tissue of the palate and inserts the fixation of the cruciate fixture or fixes the piece to the bone in the screw hole. 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 has to remove all the pieces or screws inserted in the bone and 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. In addition, the width of the slot for fixing the fixture is relatively wide in the longitudinal direction has a problem that the insertion force is relatively shortened because the length is inserted into the bone due to the increase in the length of the slot within the same piece or screw length.

And Patent Publication 2001-0062832 discloses the structure of the support structure for fixing teeth. The disclosed orthodontic support structure includes a transplant unit to be implanted in a predetermined area in the jawbone, and a bonding unit attached to an upper portion of the implant unit, wherein the bonding unit includes a female part having a tightening part extending into the oral cavity and the transplant unit. And an engaging portion having one end of an opening formed to be detachably mounted to the implantation unit in a direction intersecting the longitudinal axis of the implantation unit.

However, the orthodontic support structure as described above includes an engaging portion coupled to the implantation unit, and has a separate fastening portion extending from the engaging portion to facilitate mounting, but has a relatively weak bearing force because it has one implantation unit.

In view of this point, the present inventor has filed a "Orthodontic Fixing Device" that supplements the above problems with Korean Utility Model Registration No. 353672, and continuously studies the orthodontic fixing device for the jawbone, gum pad or mouth. Subsequent applications for implants and orthodontic orthodontic appliances using the same to increase the bearing capacity and relatively increase the corrective force of the bones of the patient have been reached.

Therefore, the present invention can improve the bearing capacity of the palatal palate bones in consideration of the above-described point, can increase the bonding force with the wire, can provide a relatively large orthodontic implant and orthodontic using the same The purpose is to provide a fixing device.

Another object of the present invention is to provide an orthodontic fixing device which can easily combine and detach the plate to which the implant and the wire are fixed, and can increase the adhesion to the jawbone or the frontal bone.

Still another object of the present invention is to provide an implant for stably engaging by allowing the corrective force acting on the wire to be coupled to the wire when acting on the center of the screw portion.

In particular, when the support of the implant is eccentric, the rotational force acting on the implant can be substantially prevented by coinciding with the central axis of the screw on the support of the wire. In addition, since the distance between the upper and lower head portion is formed to be narrower than the length of the shortest distance from the outer peripheral surface of the support portion can increase the holding force of the plate and the wire fixed thereto.
