Method and apparatus for supporting dental implantation surgery

摘要

Controlling the position of a surgical tool 113 such as a drill mounted on a robot 111to an implantation position in an oral cavity of a patient is based on a relationship between a position of a reference site in a three-dimensional computed tomography CT image and a position of a reference site in a three-dimensional optical image. A three-dimensional CT image of jaws is acquired and a reference site of the jaws and an implant implantation position of a gum in the jaws are set in the three-dimensional CT image. A three-dimensional optical image of an inside of an oral cavity is then produced, in which the reference site is positionally set through shape recognition. The three-dimensional optical image may be updated at regular intervals, to detect movement of the patients face, and the position of the surgical tool is corrected accordingly.
