  Simulation and modeling represent promising tools for several application
domains from engineering to forensic science and medicine. Advances in 3D
imaging technology convey paradigms such as augmented reality (AR) and mixed
reality inside promising simulation tools for the training industry. Motivated
by the requirement for superimposing anatomically correct 3D models on a Human
Patient Simulator (HPS) and visualizing them in an AR environment, the purpose
of this research effort is to derive method for scaling a source human mandible
to a target human mandible. Results show that, given a distance between two
same landmarks on two different mandibles, a relative scaling factor may be
computed. Using this scaling factor, results show that a 3D virtual mandible
model can be made morphometrically equivalent to a real target-specific
mandible within a 1.30 millimeter average error bound. The virtual mandible may
be further used as a reference target for registering other anatomical models,
such as the lungs, on the HPS. Such registration will be made possible by
physical constraints among the mandible and the spinal column in the horizontal
normal rest position.
