Problems solved by technology

It is more difficult to fit and remove clear aligners with multiple attachments attached to the teeth
In addition, it is easy to cause deformation when attaching and detaching to the teeth, and the attachment is easy to fall off
[0014] Since the transparent corrective device is not easily recognized from the outside, it has the advantage that it can greatly help correct the daily social life of the patient, and has the advantage that the patient can wear or remove the corrective device as needed, but as mentioned above, based on the characteristics of hard materials The transparent orthodontic device is hard, causing pain to the patient is a big problem, and there is a problem that the device is not easy to install and it is difficult to move the teeth as expected. There is also a problem that the transparent orthodontic device needs to be remade when the transparent orthodontic device is not suitable. question

Abstract

The present invention pertains to a photocurable composition for a 3D printer for producing a transparent orthodontic device. A photocurable composition for a 3D printer can be provided, which has excellent physical properties such as thermal properties, strength, elastic modulus, and tensile elongation, and when used in a patient-customized transparent orthodontic device, the orthodontic device can reduce the pain felt by patients and can enhance orthodontic correction effectiveness due to being closely fitted to the dental structure. Moreover, a 3D-printed transparent orthodontic device canbe produced which can be restored to the original shape thereof even when deformed from use.

Description

technical field [0001] The present invention relates to a photocurable polymer composition for 3D printers used to manufacture transparent correction devices, more particularly to a photocurable composition for 3D printers capable of manufacturing transparent correction devices, which is a photocurable composition for 3D printers. Composition, and the above-mentioned correction device is made of a transparent material, which is not easy to be recognized from the outside, and can be restored to its original shape by heating, so even if it is deformed due to use, it can be easily restored to its original shape and used again. Background technique [0002] Usually, uneven dentition, malocclusion, and protruding face occur when the teeth and the oral and maxillofacial areas do not grow neatly in proper positions due to abnormal development of the teeth or jaw, bad habits affecting the teeth, or genetics. The structure of the dentition and oral cavity is an important factor that ...
