Abstract
The present invention relates to a water-soluble or biodegradable polymer; And at least one selected from the group consisting of ethanol and water, and is coated on the orthodontic wire to provide an orthodontic coating composition. Thus, the coating composition for orthodontic treatment of the present invention can be easily applied to teeth by coating on wires after water-soluble or biodegradable.
Description
The present invention relates to a coating composition for orthodontic treatment and a method of manufacturing the same, and more particularly, to a coating composition for orthodontic treatment which can easily perform orthodontic treatment by directly applying a coating composition for orthodontic treatment to a wire, To compositions and methods of making the same.
Orthodontic treatment is called "malocclusion" when the teeth are not aligned or the up and down engagement is out of the normal range. In the case of malocclusion, various orthodontic appliances are used to catch malocclusion because they are not only not good for viewing, but also impair pronunciation and chewing function.
The most typical of these is the bracket, which can be used with orthodontic wires to move teeth. The bracket basically has the function of guiding the tooth to slide along the wire while continuously transmitting the restoring force generated by the warped wire in the shape of a crooked tooth to the tooth.
However, the brackets are very uncomfortable due to the relatively large and complicated structure, and the brackets are visible during treatment, resulting in a loss of aesthetics.
In order to overcome such disadvantages, an orthodontic method using a mini tube and a wire in the form of a small hollow tube is also used. Such a procedure is described in Korean Patent No. 1,234,205 'Orthodontic Therapy Tubes'.
However, the orthodontic method using a mini tube has the following fundamental problems.
First, it is very difficult to insert a wire into a mini tube having a small inner diameter of about 0.5 mm attached to irregularly crooked teeth in the oral cavity.
Second, because it is fundamentally impossible to insert a wire from the back of the neck, the mini tube can not be used for posterior teeth (molar teeth) and can only be used for partial orthodontic treatment, which is practically limited to the anterior teeth (front teeth).
Therefore, it is necessary to develop a simple and universal method that can perform orthodontic treatment in the posterior part while minimizing patient inconvenience.

[Example]
Hereinafter, preferred embodiments of the present invention will be described. However, this is for illustrative purposes only, and thus the scope of the present invention is not limited thereto.
Example 1: Preparation of a coating composition for orthodontics
100 parts by weight of polyvinyl alcohol, 400 parts by weight of water and 1 part by weight of xylitol were mixed to prepare a coating composition for orthodontic correction.
Example 2: Preparation of coating compositions for orthodontics
50 parts by weight of polyvinylpyrridone, 50 parts by weight of polyethylene glycol, 400 parts by weight of ethanol, 1 part by weight of tween 80 and 1 part by weight of xylitol were mixed to prepare a coating composition for orthodontic correction.
Example 3: Preparation of a composite for orthodontics
The coating composition for orthodontic treatment according to Example 1 was coated on a portion of the wire to be subjected to the orthodontic treatment and then dried with dry air at 50 ° C for 5 minutes to prepare an orthodontic composite.
Example 4: Preparation of a dental orthodontic composite
The coating composition for orthodontic treatment according to Example 2 was coated on the portion of the wire to be subjected to the orthodontic treatment and then dried with dry air at 50 DEG C for 5 minutes to prepare an orthodontic composite.
[Test Example]
Clinical Test Example 1: Orthodontic correction using an orthodontic composite
The clinical test procedure of orthodontics using the dental orthodontic composite prepared according to Example 4 is shown in Fig. 1, and the results are shown in Fig.
Referring to Figures 1 and 2, the orthodontic composite prepared according to Example 4 was directly bonded to the teeth. As a result, it was possible to apply it to posterior teeth.
Thus, it can be seen that the dental orthodontic composite prepared in Example 4 is aesthetically simple, has no soft tissue stimulation by the device, is comfortable, and can easily maintain oral hygiene.
Clinical Comparative Test Example 1: Orthodontic correction using a conventional bracket
The results of the orthodontic treatment using a conventional bracket are shown in Fig.
Referring to FIG. 3, after a conventional bracket is bonded to a tooth, the wire is bound so as not to be pulled out of the bracket by using a binding tie. As a result, brackets and their attachments with large and complicated structures were found to stimulate soft tissues in the oral cavity.
Therefore, it has been found that the conventional bracket is not aesthetic due to a complicated structure, stimulates the soft tissues in the oral cavity, and makes oral hygiene maintenance difficult.
Clinical Comparative Test Example 2: Orthodontic correction using hollow tube type tube
FIG. 4 shows a photograph of the orthodontic treatment using a conventional hollow tube type tube.
Referring to FIG. 4, a conventional tube-shaped tube is bonded to teeth, and then the wires are sequentially inserted. As a result, since it is fundamentally impossible to insert the wire from the back of the neck, it can be applied only to partial orthodontic treatment limited to the anterior part.
Therefore, it can be seen that the hollow tube type tube can be applied only to the partial orthodontic treatment limited to the anterior portion, and it takes much time to insert the wire.
The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
