The basic framework for the development of dental treatment systems and the development of clinical teaching materials is an ID number that can systematically classify all possible partial edentulous conditions that can be caused by a single tooth or multiple tooth loss in the mouth, It is essential to create a database that is reasonably manageable. Since the teeth are symmetrical and the healthy teeth have seven teeth on one side, the possible number of tooth loss cases on one side is 128, which is the 7th power of 2, and the number of partial edentulous dental arches that can occur together on both left and right sides is 128 X 128 is 16,384. For systematic file management and folder management, ID index numbers from 1 to 128 are assigned to the number of cases that can occur sequentially on one side of teeth according to increase or decrease of tooth loss number. The left unilateral dental arch image and the right unilateral dental arch image were recorded with 128 left and right unilateral dental arch images, respectively, 1: 1, and total 16,384 dental arch shapes were produced. This is done in the same way for maxilla and mandible. For each completed dental arch shape, a 7 digit number is assigned to the ID index number. The first digit is assigned 1 and 6 for the upper and lower dentition, the ID index for the right side of the dental arch, For the 3 digits, the number ID index is assigned to the left side of the dental arch. Design the database so that the image files with the right dental arch shape are stored in the storage folder of the name having the digit number of 3 digits of the right dental arch case ID index and the digit of 1 digit having the upper and lower dental arch information, and systematically managed.치과 치료 시스템 개발이나 임상 교육 자료 개발을 위한 기본 framework로 구강 내의 단일 치아 혹은 다수 치아 상실에 의해 초래될 수 있는 가능한 모든 부분 무치악 상태를 체계적으로 분류하여 표기할 수 있는 ID 번호와 그 치열궁의 이미지를 합리적으로 관리할 수 있는 데이터베이스 제작이 필수적이다.치열은 좌우 대칭이고 건강한 치열은 편측에 7개의 치아가 있기 때문에 편측에서 가능한 치아의 상실 경우 수는 2의 7승 숫자
