Implant surgery may be performed more precisely and effectively, according to one embodiment of the present invention, by precisely and automatically calculating an implantation position, an implantation angle, and the depth of a dental implant so as not to damage the inferior alveolar nerve after dividing a CT image obtained by photographing teeth into a teeth region, which comprises the teeth, the maxillary sinus, the alveolar bone/cortical bone, and the inferior alveolar nerve, and selecting the position of a missing tooth by using the dental arch. |
