Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for manufacturing an orthodontic appliance,

The present invention relates to a device for manufacturing a tooth straightener and a method of manufacturing a tooth straightener using the same, and more particularly, to a device for manufacturing a straightener of a tooth and a method of manufacturing a tooth straightener using the same, will be.

Occlusion refers to the state in which the teeth of the upper and lower jaws engage with each other when their mouths are closed. Malocclusion refers to an occlusal relationship in which the teeth are not aligned due to some cause, or the state of the upper and lower engagement is out of the normal position, resulting in aesthetic and functional problems.

The major causes of malocclusion are known to be genetic influences. Malocclusion is caused by various causes such as tooth shape, size, environmental effects, bad habits, wrong postures, dental caries, and congenital disorders such as cleft lip and cleft .

If malocclusion occurs, teeth arrangement is not uniform and food residue is likely to remain between the teeth. Because it is not easy to manage cleanly with accurate brushing, the plaque in the mouth increases, and it is likely to progress to gum disease such as dental caries or gingival inflammation. In addition, if there is a tooth that deviates much from the normal dentition or if the position of the jaw is abnormal, there is a high possibility that the teeth are damaged, such as a tooth fracture, when an external shock is applied.

Treating such malocclusion is orthodontic treatment or orthodontic treatment. Orthodontic treatment uses the property that the tooth moves when it receives some force. Treatment of malocclusion uses a variety of devices and methods depending on the cause and timing of treatment. A device designed to remove habit, a device for suppressing or enhancing the development of the upper and lower jawbone, and a device for slowly moving the tooth to a desired position, and a removable device that can be inserted and removed in the oral cavity. It can also be divided into removable fixed devices.

Currently the most commonly used type is a fixed treatment method in which a device called a bracket is attached to a tooth and the tooth is moved by using the elasticity of the wire and the rubber band for orthodontic treatment and is commonly used in most malocclusion. Brackets are usually made of metal, but there are conspicuous disadvantages during treatment.

In order to solve these drawbacks, a method of orthodontics using transpatent aligner has been proposed. Transparent correction is a procedure to make clear orthodontic appliances that change stepwise from the state of the tooth before correction to the state of the tooth after correction, and correct the dentition by changing it to the teeth. The orthodontic appliance used in transparent correction is made of transparent plastic, so it has a good sense of aesthetics.

Generally, an orthodontic appliance used for transparent correction is formed by making a mold by making a tooth by drawing a bone of a tooth, placing a thin transparent plastic sheet on the mold, applying negative pressure to the mold while applying heat, or applying a positive pressure to the sheet.

1 is an exemplary view showing a manufacturing process of a conventional orthodontic appliance.

As shown in FIG. 1 (a), the mold 20 is provided on the upper side of the molding plate 10 in a tooth shape. The forming sheet 30 is fixed to the clamping portion 40 at the upper side of the mold 20 and the forming sheet 30 is heated by the heating portion 50.

Thereafter, as shown in Fig. 1 (b), the clamping portion 40 is lowered to the forming plate 10, and the forming sheet 30 is heated and thus is put downward by gravity. Then, high pressure air is applied to the forming sheet (30) by the pressing portion (60) and pressed.

Then, as shown in Fig. 1 (c), the forming sheet 30 is put on the mold 20 so as to be brought into close contact with the mold 20, and is then made into a tooth straightener through hardening and edge cutting.

On the other hand, because the tooth shape and root strength of the root are different from each other, the movement characteristics of the tooth are inevitably varied. However, the orthodontic appliance manufactured through such a conventional manufacturing process always has a certain thickness when the thickness of the formed sheet 30 is the same. Therefore, there is a need for a technique capable of shaping by adjusting the thickness of the orthodontic appliance so that an appropriate orthodontic force can be provided in accordance with the wearer's tooth movement characteristics.

As shown in FIG. 12, the method of manufacturing a tooth straightener using a tooth straightener manufacturing apparatus may include a step S1110 in which a toothed mold is provided at the upper center of the base.

In addition, a step S1120 may be performed in which a forming sheet covering a tooth-shaped mold is coupled to a clamping portion provided on the upper side of the base so as to be moved up and down.

Thereafter, step S1130 may be performed in which the clamping portion is lowered and supported by a stopper protruding from the base portion so as to surround the tooth-shaped mold.

In step S1130, the stopper may support the lower portion of the clamping portion when the clamping portion is lowered, thereby limiting the descending height of the clamping portion. The height of the stopper can be variable and the distance from the tooth mold can be varied. Accordingly, the thickness of the formed sheet covering the outer portion of the teeth of the tooth of the tooth can be adjusted, so that the correcting force The thickness of the orthodontic appliance can be adjusted so that it can be provided.

Next, step S1140 in which the heating unit provided on the upper side of the clamping unit generates heat to heat the formed sheet can proceed. In a state in which the clamping portion is in close contact with and supported by the stopper, the pressing portion may spray high-pressure air from the upper side of the forming sheet toward the forming sheet, and pressurize the heated forming sheet so as to cover the tooth mold (S1150).

After the step S1150, the formed sheet covered with the tooth-shaped mold can be cured, and the process of cutting the edge and proceeding to obtain the tooth straightener can proceed.

FIG. 13 is a flowchart illustrating a method of manufacturing a tooth straightener using the apparatus for manufacturing a straightener according to a second embodiment of the present invention.

As shown in FIG. 13, the method of manufacturing a tooth straightener using a tooth straightener manufacturing apparatus may include a step S1210 in which a toothed mold is provided at the upper center of the base.

The step S1220 may include a step of joining a forming sheet covering the tooth-shaped mold to the clamping unit, which is provided on the upper side of the base so as to move in the vertical direction.

Thereafter, step S1230 in which the clamping part is lowered and brought into close contact with the base part may proceed, and step S1240 may be performed in which the heating part provided on the upper side of the clamping part generates heat to heat the formed sheet.

In a state in which the center portion of the heated molded sheet is supported on the support portion protruding from the base portion so as to be positioned on the inner side of the tooth-shaped mold, the pressurized portion injects high- The step of pressing the sheet to cover the toothed mold (S1250) may proceed.

In step S1250, the distance between the height and the toothed mold can be varied so that the thickness of the formed sheet put on the inner side of the tooth of the toothed mold can be adjusted.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
