The skull was placed with the Frankfort plane (Lundstrom & Lundstrom, 1995) parallel to the floor and the axis of the light beam in the median plane. In the edentulous skulls a support was placed interdentally to leave an intercrestal space of approximately 15 mm; for this purpose, thick, non-deforming foam wedges were used to simulate the presence of teeth, thus maintaining the vertical dimension of the skull and the stability of the temporomandibular articulation.
