SHELL DESIGN PROCESSING METHOD FOR CLEAR ALIGNER FOR DIRECT 3D PRINTING
The present invention relates to a shell design processing technology for manufacturing a clear aligner by using direct 3D printing. In particular, the present invention relates to a shell design processing technology capable of personalizing a clear aligner and improving the orthodontic effect by designating a specific shell region and a specific structure (e.g., attachment) region and adjusting the shell thickness or gap for a standard aligner design in a process of designing a clear aligner for direct 3D printing by computer software. According to the present invention, there is an advantage in that a clear aligner can be manufactured, in which the shell thickness or gap of the specific shell region and the specific structure region is different from that of other parts of the aligner. Accordingly, a clear aligner suitable for a tooth structure of a patient can be manufactured. In addition, the orthodontic effect can be enhanced by adjusting a force applied to a specific part of teeth or a tooth mounting force by a structure (e.g., attachment), and the aesthetics can be improved by reducing the use of the attachment compared to the related art..
