Image generation system for implant diagnosis and generation method thereof

A method of generating an image for implant diagnosis, the method comprising:

• a first image information acquirement operation of acquiring first 3D image data about a mouth area of a target patient;
• a second image information acquirement operation of acquiring second 3D image data by scanning plaster patterns of teeth of the target patient;
• and
• a synthetic 3D image data acquirement operation of generating synthetic 3D image data by matching the first 3D image data and the second 3D image data,
• wherein the second image information acquirement operation comprises providing a matching reference marker for matching the first 3D image data and the second 3D image data on the plaster patterns of teeth of the target patient, and
• the synthetic 3D image data acquirement operation comprises a pre-matching operation of pre-matching the first 3D image data to the second 3D image data based on a coordinate of the matching reference marker of the second 3D image data.
