Abstract
Provided is a method for manufacturing a surgical guide, and a crown and an abutment in a mouth for a dental implant, including an operation of obtaining a primarily scanned image through scanning of inner and outer surfaces of a denture which has a first image matching groove matched with a patient's tooth implanting portion and in which a plurality of reference markers are attached to an outside, obtaining a secondarily scanned image through oral scanning of upper and lower jaws while the denture is installed, preliminarily matching the secondarily scanned image with the primarily scanned image, obtaining an integrated scanned image considering a vertical dimension by reversing the first image matching groove so that an image of the first image matching groove is dimensionalized from the primarily scanned image, and obtaining a CT image through CT scanning of the upper and lower jaws.
