Abstract
An intraoral scanner having a tomography function capable of setting a tomography area using shape information of an oral cavity includes a shape measurement light projector that irradiates shape measurement light for obtaining a shape image of an oral structure; a shape measurement camera that obtains a surface shape image of the oral structure by detecting reflected light; an optical coherence tomography (OCT) body that transmits tomography measurement light to the oral structure and detect reflected light to obtain an internal cross-sectional image of the oral structure; an OCT scan probe that irradiates the tomography measurement light emitted from the OCT body onto a desired position of the oral structure and transfer the reflected light to the OCT body; and a beam splitter that superimposes optical paths of the shape measurement light irradiated from the shape measurement light projector and the tomography measurement light irradiated from the OCT scan probe.
