    COMMERCIAL interest ON (Non-commercial comments below :-)

    You might want to consider my Mvox software. It will do rigid
    registration based on markers (put markers on the most stable
    teeth etc), and you can use to view the CTs and create computer
    graphics models from them.

    It has previously been used for creating computer graphics models
    of teeth and jaws.

    In addition it has been used to generate surface models of femurs
    for use in generating FEM meshes for the femur (mesh generated
    afterwards in COSMOS).

    Take a look at

    COMMERCIAL interest OFF

    I believe any metal artifacts (at least teeth fillings) will generate
    star-like spikes around the artifact. One way to get rid
    off it is to filter the image afterwards. It doesn't remove the spikes
    completely, though.

    This reference is about handling the problem:

    For registration, you will probably want to use either manual
    using markers (as in Mvox) or surface based registration (several
    approaches - rough ICM registration available in Mvox).

    For more information on registration take a look at my PhD thesis:
