Abstract: The present invention generally relates to a dental intraoral scanner system. In detail, the present invention includes: a scan unit sequentially imaging an intraoral structure in a scan mode; a control unit generating a three-dimensional modeling image for each scan mode by using the imaged intraoral structure; and a display unit displaying the three-dimensional modeling image, wherein the control unit switches the scan unit from a present scan mode to a following scan mode according to a user's command that is input through the scanning unit, or automatically switches from the present scan mode to the following scan mode when a three-dimensional modeling image of the present scan mode is completed.
