  • Publication number: 20210401549
    Abstract: The present invention relates to a digital scan body alignment method and a device using the same. The present invention corrects scan data through library data corresponding to image data on oral structure. At that time, to achieve best-fit of aligning the library data to the scan data initially, the data alignment can be performed by using a first alignment step. In order to accomplish data correction by more accurate data alignment, a second alignment step can be performed using the library data which includes shape information and axis information. By performing the second alignment step, corrected data having higher reliability can be formed, and a more precise prosthesis can be provided to a patient.
