Abstract: Provided is a method of setting a scan region, the method including: placing a target object on an upper surface of a jig of a three-dimensional scanner in such a manner that at least one portion of a target object image representing a shape of the target object is plotted on an input region; determining, by a control unit, a predetermined upper portion of the input region, as a scan region, from a jig image representing the shape of the jig; and generating, by the control unit, a three-dimensional model of the target object on the basis of the target object image resulting from scanning the scan region.

Abstract: The present invention relates to a method of processing three-dimensional scan data for manufacture of dental prosthesis, the method identifies a position for an implant procedure on the basis of image data for an oral structure, and generates aligned image data by retrieving, from a library, data corresponding to a scan body or an abutment, only a part of which has been scanned, by replacing a part or the whole of the image data with the retrieved data, and by aligning a position and a direction of the image data. By using the method, user can easily identify an oral structure from the image data obtained by scanning partial shape of the scan body or the abutment, and the method provides feedback to the user so that the method guides the user to correct measurement. Therefore, the prosthesis can be manufactured more quickly due to reduced scan time.
