Wax bite for scanning, and dental restoration manufacturing method using same

Abstract

The present invention provides a dental restoration manufacturing method for improving the precision and reliability of a dental restoration, the dental restoration manufacturing method comprising: a first step for acquiring, through an imaging device, each of a scanning image of a part where implantation is to take place and a corresponding antagonistic part, before the mounting of a coupling bite disposed between the part where implantation is to take place and the corresponding antagonistic part, and after the mounting of the inner and outer surface portions of the coupling bite in consideration of a vertical dimension of a patient by occlusal pressure, a CT image of the oral cavity occluded by means of the coupling bite, and a gothic arch motion image of a three-dimensional motion trajectory of the temporomandibular joint of the patient in a state where a mastication protrusion part, provided on the coupling bite, and the corresponding antagonistic part are mutually occluded, and transmitting the images to a planning unit; a second step for generating an integrated scanning image by aligning and arranging a plurality of the scanning images so that same correspond to the vertical dimension, wherein a three-dimensional planning image is generated by overlapping and matching the integrated scanning image on the basis of a common portion between same and the CT image; a third step for, on the basis of the three-dimensional planning image, generating and arranging dental restoration design information including a virtual masticatory surface, and displaying an overlapping occlusal area on the virtual masticatory surface by overlapping the motion image on the dental restoration design information; and a fourth step for correcting the dental restoration design information by configuring an overlapping elimination area of the overlapping occlusal area, and manufacturing a dental restoration by transmitting the corrected dental restoration design information to a manufacturing apparatus.
