Jig for forming orthodontic wires {MOULDING JIG FOR ORTHODONTIC ARCH WIRE}

The present invention relates to a jig for forming orthodontic wire, and in particular, the structure of the orthodontic wire improved by improving the structure so that the wire rod can be easily formed into a curved orthodontic wire by using the first and second molding jig and a heating furnace. It is about a dragon jig.

In general, appearance, especially impression, serves as a criterion for judging people during job interviews and admissions, and plays a very important role in social life, especially in interpersonal relationships. In recent years, dental plastic surgery and orthodontics for the improvement of the teeth, dentition, or facial skeleton have been prevalent.

The orthodontics is a concept including an orthodontic treatment, for example, an orthodontic treatment that simply aligns a crooked tooth, and corrects various skeletal inconsistencies that may occur during the growth process, thereby exerting a normal function. By contributing to healthy oral tissues, the facial lines can also be beautiful to create beautiful facial images.

The orthodontic surgery may be divided into orthodontic treatment (Orthodontic Treatment) to improve the orthodontic teeth such as malocclusion through the progressive movement of the orthodontic and orthodontic surgery to give a skeletal improvement by performing a surgical operation on the jawbone.

In other words, the abnormality of the upper teeth and the facial skeletal structure is so severe that it can not be treated by orthodontic surgery alone. In this case, the abnormality of the facial skeleton itself is surgically corrected to correct the functional and esthetic face. Orthognathic surgery may be applied in conjunction with the orthodontic surgery to make it.

In particular, in the case of growing children, the orthodontic surgery may be avoided by using a method such as skeletal improvement through orthodontic surgery, but in the case of adult growth, the operation may be difficult by orthodontics alone. Surgery may be performed in parallel with the orthodontic procedure.

The orthodontic treatment may be largely divided into a labyrinthol and lingual correction, the labyrinth correction is a correction method for performing orthodontics by attaching the orthodontic appliance used for orthodontics to the surface of the lips side of the teeth, The orthodontic appliance is a method of orthodontic treatment by attaching the orthodontic appliance to the surface of the tongue of the surface of the tooth.

Examples of the orthodontic appliance include orthodontic wires (generally referred to as 'wire wires') and brackets for supporting the orthodontic wires, the brackets being provided on the labial and / or lingual surfaces of the teeth. It is fixed. The brackets are provided in plural along the alignment direction of the teeth, and are connected by the straightening wires, and transfer the straightening force applied from the straightening wires to the teeth.

The orthodontic treatment is performed in a plurality of correction steps sequentially and takes a long time, such as in the case of a patient showing the densities of the anterior teeth of the anterior teeth or a patient gap between the teeth of the anterior teeth as an example of the orthodontic surgery There is a procedure to adjust neatly using the wire wire and the bracket.

On the other hand, the orthodontic procedure for moving the dentition to the lingual during the orthodontic procedure is called lingual traction, in the case of a tooth protrusion in which the patient's orthodontic state is an abnormally protruding shape, the mouth shows an abnormally protruding protrusion mouth phenomenon. Therefore, the above-described lingual traction is presented as one method for this protruding mouth correction.

The mouth of a normal person corresponds to the line between the tip of the nose and the chin and the upper lip is located slightly inward of the line, whereas the protruding mouth refers to the shape of the mouth outside the line between the tip of the nose and the chin. This may be due to tooth protrusion or gum protrusion (skeletal protrusion).

The protruding teeth are a kind of malocclusion with the anterior inclination protruding relatively excessively forward compared to the end root of the crown due to the growth of the gum bone insufficient to accommodate the current number of teeth. It is difficult to shut up and may adversely affect the overall impression.

An orthodontic system is installed inside the patient's mouth for the correction of the protruding mouth, but conventionally, the teeth of the anterior part are excessively lingually in the process of the tooth being shortened or the teeth being pulled backward while the anterior teeth are pulled backward. This is caused by a slanted sloping and severe sloping of the anterior part, which causes the inclination of the anterior side to be inclined in the lateral direction. At the same time, a long treatment period and expensive costs were required.
