Outline of Final Research Achievements

We extracted the outline shape of teeth from the picture of the surgical camera by computerization.　Extraction of characteristic points and teeth matching were done using images from a surgical camera for patient-image registration.　We compared the shapes of the part corresponding to the teeth of the CT image and alined it.　We superimposed a three-dimensional CT image and the computer simulation image of the orthodontic anchoring screw on the picture of the surgical camera and displayed it.
