In general, uneven dentition, malocclusion, facial asymmetry, or crooked jaw are most often caused by the failure of the teeth and oral cavity to grow properly in place due to abnormal development of teeth or jawbone, bad habits affecting teeth, or heredity. .

These various abnormal conditions have a rather negative effect on an individual's first impression and cause discomfort in daily life such as food intake. This is the reason why the interest in orthodontics or maxillary orthopedics continues.

The principle of orthodontic treatment is to utilize the property of teeth to move when subjected to a certain force. There are several methods for orthodontic treatment, one of which is to fix a bracket to the teeth and connect the bracket with a wire. However, since the bracket and wire are made of metal, they have the disadvantages of being easily visible and inconvenient to manage.

Another method of orthodontic treatment is to use a transparent orthodontic device. Transparent aligners are invisible from the outside and can be freely installed and detached as needed, so they are widely used for adults.

In general, the manufacturing process of transparent orthodontic devices is a digital orthodontic model that scans the initial tooth condition of a dental patient first, then processes the dental scan data by a program that generates orthodontic teeth, and gradually moves the teeth to the set final tooth position. is created step by step. Then, the orthodontic model for each stage is output to the tooth mold through a 3D printer, and thermoformed plastic is molded into the output tooth mold in a compression method to produce a transparent brace set.

In the manufacturing method of the transparent orthodontic device as described above, since the orthodontic diagnosis and treatment plan are established depending on the subjective ability or experience of the dentist, a misdiagnosis for the application of transparent orthodontic treatment may occur, and there may be variations in the treatment success rate for each dentist. may occur. In addition, there is a limitation in providing a digital orthodontic model optimized for each stage because the program for generating orthodontic teeth adjusts and provides the digital orthodontic model for each stage at equal intervals through a simple engineering calculation method.

In addition, the dental mold may be directly output from the dentist in the case of a dentist having a 3D printer, or may be made of plaster through a dental laboratory by taking a dental impression body in the case of a dentist without a 3D printer.

However, since transparent braces can be manufactured only in specialized dental laboratories equipped with vacuum thermoforming processing equipment, it takes a long production period of at least 7 days to a maximum of 30 days until a patient visits the dentist for a diagnosis and is provided with a transparent brace. In addition, if a problem occurs after wearing the transparent braces, the manufacturing period of the transparent braces may be extended because the process of manufacturing through the dental laboratory must be repeated again.
