Method, apparatus, and computer program for planning implant surgery

A system for supporting implant surgery, comprising:

• a guide model manufactured to a standard to group human teeth in any range so that the teeth belong to at least one group and to cover a tooth position of a corresponding group, the guide model comprising a marker made of a radiopaque or radiation semipermeable material;
• a CT scanner for scanning a subject's oral CT image with the guide model inserted into an oral cavity of the subject;
• a storage unit configured to store a library comprising a database, the database including information about shape, size, image, material of the guide model, and a position of the marker of the guide model;
• and
• a server configured to load a library as information about the standard of the guide model, to identify the marker in the oral CT image, to generate a library matching CT image by matching the oral CT image with the library based on the marker included in the library and the marker identified in the oral CT image, and to plan implant surgery of the subject using the library matching CT image, wherein the oral CT image comprises a maxillary image and a mandibular image, and the server is further configured to correct an error associated with a thickness of the guide model by separating the maxillary image and the mandibular image and reconstructing the separated maxillary image and mandibular image for occlusion;
• and
• wherein the guide model further comprises a maxillary model and a mandibular model, the maxillary model is configured to cover a portion of maxillary teeth, and the mandibular model is configured to cover a portion of mandibular teeth.

A server for supporting implant surgery, comprising:

• a storage unit configured to store a library as information about the standard of a guide model, the guide model being manufactured to a standard to group human teeth in any range so that the teeth belong to at least one group and to cover a tooth position of a corresponding group, the guide model comprising a marker made of a radiopaque or radiation semipermeable material, the library comprising a database including information about shape, size, image, material of the guide model, and a position of the marker of the guide model;
• an image processing module configured to identify the marker of the guide model in a subject's oral CT image scanned with the guide model inserted into an oral cavity of the subject and to generate a library matching CT image by matching the oral CT image with the library based on the marker included in the library and the marker identified in the oral CT image, wherein the oral CT image comprises a maxillary image and a mandibular image, and the image processing module is further configured to correct an error associated with a thickness of the guide model by separating the maxillary image and the mandibular image and reconstructing the separated maxillary image and mandibular image for occlusion;
• and
• an implant planning module configured to plan implant surgery of the subject using the library matching CT image.

A non-transitory computer readable medium configured to perform a function of supporting implant surgery in a server, performing:

• a function of obtaining a subject's oral CT image scanned with a guide model inserted into an oral cavity of the subject, the guide model being manufactured to a standard to group human teeth in any range so that the teeth belong to at least one group and to cover a tooth position of a corresponding group, the guide model comprising a marker made of a radiopaque or radiation semipermeable material;
• a function of loading a library as information about the standard of the guide model, identifying the marker in the oral CT image, and generating a library matching CT image by matching the oral CT image with the library based on the marker included in the library and the marker identified in the oral CT image;
• and
• a function of planning implant surgery of the subject using the library matching CT image;
• wherein the library comprises a database pre-stored in a storage unit, the database includes information about shape, size, image, material of the guide model, and a position of the marker of the guide model;
• and
• wherein the oral CT image comprises a maxillary image and a mandibular image, and the non-transitory computer readable medium is further configured to perform a function of correcting an error associated with a thickness of the guide model by separating the maxillary image and the mandibular image and reconstructing the separated maxillary image and mandibular image for occlusion.
