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.
Claims21
A method for aligning a digital scanbody, comprising:
- a library data selection step of selecting one or more library data among a plurality of library model data stored in a library by a control unit;
- an image acquisition step of acquiring image data by scanning an oral structure including a structure through a scanner;
- and
- an alignment step of aligning the image data and the library data by the control unit,
- wherein in the alignment step, the structure in the image data and the library data is matched and aligned based on at least one of central axis, direction, and height of the library data,
- wherein a corrected scanbody is generated to correct insufficiently scanned data of scan data included in the image data, by coupling the library data and the scan data, and
- wherein the library data have information of the central axis and information of the height based on a curved shape and a top surface shape.
