Abstract: The present invention relates to an occlusal vertical dimension reproduction method for denture fabrication and, more specifically, to an occlusal vertical dimension reproduction method for denture fabrication, wherein three-dimensional scan data is used to calculate the occlusal vertical dimension required to denture fabrication. The occlusal vertical dimension reproduction method for denture fabrication according to the present invention has an advantage that the occlusal vertical dimension for effectively denture fabrication can be easily determined while minimizing the number of direct scans of the upper jaw and the lower jaw of a patient in an edentulous state or occlusal state to reproduce, in a virtual space, the occlusal state of the oral cavity of the patient wearing denture or denture structure. The occlusal vertical dimension reproduction method for denture fabrication according to the present invention has the effect of reducing inconvenience of a patient and operator during the process of denture fabrication compared to the prior art.

Abstract: A pulp cavity distance measurement system according to the present invention comprises: a first scan unit which acquires surface data; and a second scan unit which acquires volume data that is scan information different from the surface data, wherein the surface data and volume data are delivered via a database unit included in a control unit, and are merged into a single piece of data by a data merging unit. The shortest distance (pulp cavity distance) from the surface of the enamel of a tooth to the surface of the pulp cavity is calculated from the merged data, and the pulp cavity distance may be visually displayed by a distance stage display unit by using the calculated distance information (data). Here, the visual display may be expressed using colors or patterns having specific markings, and have a plurality of patterns so that the distance is displayed so as to be divided in stages. Accordingly, the system is advantageous in that a therapist can minimize tooth preparation in a part in which the distance to the pulp cavity is short, and reduce the discomfort of a patient due to vibrations caused by tooth preparation.

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.
