Abstract
In a method and apparatus for supporting dental implantation surgery, a three-dimensional CT image of jaws of an object is acquired. A reference site of the jaws and an implantation position of a gum in the jaws are set in the three-dimensional CT image. The implant is implanted at the implantation position. A three-dimensional optical image of an inside of an oral cavity of the object is then produced. The reference site is positionally set in the three-dimensional optical image through recognition of a shape of the reference site in the three-dimensional optical image. A surgical tool is positionally controlled to the implantation position in the oral cavity, based on i) a relationship between the position of the reference site and the implantation position of the gum in the three-dimensional CT image and ii) the position of the reference site in the three-dimensional optical image.
