Table 3. The absolute root-mean-square distance (RMSD) for the maxilla, mandible and maxillomandibular complex comparing post-surgical 3D image and 3D simulation model.

	Forehead+ Orbital	Maxilla+ Mandible	Maxilla	Mandible
Mean	0.43	0.77	0.63	0.85
SD	0.02	0.36	0.25	0.41

The forehead and orbital areas were used for registration of the two images. The data were in mm.
