Palatal Anchorage for Orthodontic Treatment

The present invention relates to an orthodontic appliance for orthodontic treatment, and more particularly, to a palatal orthodontic palatal fixed source which is fixed to the palate, ie, the palate, and functions as an anchor when providing traction for orthodontics. will be.

For modern people, appearance, especially impression, serves as a criterion for judging people during job interviews and admissions, and plays an important role in social life. It is a factor that influences overall. Accordingly, orthodontics for the improvement of teeth, dental dentition, or facial skeleton along with plastic surgery are 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 orthodontic treatment, orthodontic treatment alone, cannot be treated. In this case, the face skeletal itself is corrected by surgery. Orthognathic surgery may be applied in conjunction with the orthodontics to create a facial that is both aesthetic and esthetic.

That is, the orthognathic surgery may be used when an orthodontic treatment is incomplete in improving the shape of the face and improving the dental function. 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 labyrinth and lingual correction, the labyrinth correction is a correction method to perform 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 side of the tooth surface.

Examples of the orthodontic appliance include a calibration wire (generally referred to as a 'wire wire') for correcting an orthodontic appliance, a wire support (generally referred to as a 'bracket') for supporting the orthodontic wire, and a traction force of the orthodontist. Anchors, which are anchors, wherein the brackets are secured to the labial and / or lingual surfaces of the teeth. The bracket is provided with a plurality along the teeth are connected by the correction wire, and transmits the correction force applied from the correction wire to the teeth.

The orthodontic treatment may be performed sequentially in a plurality of orthodontic steps, as an example of the orthodontic steps constituting the orthodontic surgery in the case of a patient showing the densities of the anterior teeth or the gap between the teeth of the anterior teeth The anterior calibration step of adjusting the teeth of the anterior teeth neatly using the wire wire and the bracket.

On the other hand, the orthodontic step of pulling the dentition to the lingual, for example palate side during the orthodontic procedure is referred to as lingual traction step, the lingual traction step according to the orthodontic state of the patient to be performed during the orthodontic procedure Alternatively, the lingual traction step may be performed after another calibration step, such as the anterior calibration step described above.

In order to perform the lingual traction step of the dentition, the orthodontic appliance for lingual traction should be installed inside the mouth of the patient, as shown in Figure 1 for lingual traction on the lingual surface of the teeth (1a, 1b, 1c) The orthodontic appliance, for example the traction wire 10, is fixed using a dental adhesive and connected to the palatal fixation source 30 via a traction member 20, such as a spring, so that lingual traction is performed.
