method for manufacturing dental restoration using occlusal vertical dimension measuring device

摘要

In order to improve the precision, the present invention is set on the outer surface portion of the virtual bonding surface that is molded and laminated on the virtual wax inner surface of the virtual general-purpose wax bite extracted from the digital library, and based on the surface information obtained with respect to the implantation target portion. A first step of generating design information of the lower base portion set on the inner surface portion of the virtual fitting surface portion corresponding to the insertion target portion; Based on the design information of the lower base part, a mating surface part corresponding to the virtual mating surface part is formed, and the lower base part on which the mating surface part corresponding to the virtual mating surface part is formed is made of a cured plastic material, and a general-purpose wax made of a pre-made paraffin wax material. A second step of preparing a vertical height measuring device in which the bite and the lower base portion are stacked and coupled to each other; A plurality of scanning images of the implantation target portion and the opposing target portion in a state in which the vertical height measuring device is heated and corrected by taking into account the vertical height of the person to be treated by the occlusal pressure, and the oral cavity occluded through the vertical height measuring device. A third step of obtaining a CT image for; A fourth step in which a plurality of the scanning images are aligned and arranged to correspond to the vertical height to generate an integrated scanning image, which is overlapped and matched based on a common portion with the CT image to generate a 3D planning image; And a fifth step of designing and manufacturing the tooth restoration considering the vertical height based on the three-dimensional planning image.
