The present invention provides a method of processing information for supporting an orthodontic treatment, capable of improving the accuracy and economic feasibility of an orthodontic treatment. The method includes: a first step of authenticating a client terminal connected to a manufacturer server through an authentication database in accordance with medical registration information, and activating an orthodontic information input module of the manufacturer server； a second step of inputting a CT image and an oral scan image of an orthodontic patient into orthodontic detail information through the client terminal, and storing the orthodontic detail information in an order database by setting the information as an order list； a third step of inputting confirmation and error information about the order information by activating an orthodontic information confirmation module of the manufacturer server through a manager terminal connected to the server； a fourth step of activating a planning module of the manufacturer server and extracting the order list, while inputting a current teeth arrangement image and a desired teeth arrangement image, in which each teeth image of the current teeth arrangement image is temporarily corrected, into orthodontic guide information in accordance with the orthodontic detail information of the extracted order list； a fifth step of inputting approval information and modification information about the orthodontic guide information by activating a planning approval module of the manufacturer server through the client terminal； and a sixth step of activating a template manufacturing module of the manufacturer server, while setting and outputting template design information for setting a template for an orthodontic treatment based on the orthodontic guide information into which the approval information has been inputted.치열교정치료의 정확성 및 경제성이 개선되도록, 본 발명은 제조사서버에 접속된 클라이언트단말기가 의료등록정보에 따라 기설정된 인증데이터베이스를 통해 인증되고 상기 제조사서버의 교정정보입력모듈이 활성화되는 제1단계； 상기 클
