Abstract
An intraoral scanner having a tomographic imaging function includes an OCT body configured to obtain an internal cross-sectional image of an oral structure; an OCT scan probe configured to irradiate the layer measurement light emitted from the OCT body onto the oral structure and transfer the reflected light to the OCT body; and a control/processing unit configured to control the OCT body, take a tomographic image of the oral structure, obtain two or more two-dimensional cross-sectional images, extract an internal crack area for the respective two-dimensional cross-sectional images, calculate cross-sectional position information of the internal crack, then arrange the position information of the internal crack obtained from the respective two-dimensional cross-sectional images in positions where the respective two-dimensional cross-sectional images have been obtained, and obtain three-dimensional shape information of the internal crack.
