Fig 1. The creation of the computerized composite skull model.

Fig 1

a. Bite-jig is created with CT/MRI compatible fiducial markers

b. The patient is biting on the bite-jig with fiducial markers during CT scan.

c. Three separate but correlated computer models are reconstructed: a midface model, a mandibular model and a four-fiducial-marker model.

d. The bite-jig with fiducial markers is placed between the upper and lower plaster dental models during the scanning process.

e. Three separate but correlated computer models are also reconstructed: an upper digital dental model, a lower digital dental model, and a four-fiducial-marker model.

f. The computerized composite skull model simultaneously displays an accurate rendition of both the bony structures and the teeth. (Color version of figure is available online.)
