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 and detecting reflected light; 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 tomographic images of the oral structure at two or more positions, obtain two or more two-dimensional cross-sectional images of the oral structure, extract an abrasion or filling area for the respective two-dimensional cross-sectional images, calculate cross-sectional position information of the abrasion or filling area, then arrange the position information of the abrasion or filling area, and obtain three-dimensional shape information of the abrasion or filling area.
