Exposure of the Temporo-mandibular Joint.
P6 Program with Head Positioner
• Insert the head positioner (see page 18).
• Remove bite block / contact segment.
• Using the ↑ and ↓ keys, adjust the unit height so that
the ear olives and external auditory canals match.
• Position the patient's head in the head positioner.
Close the temple supports so that the ear fixations are
inserted in the external auditory canals.
• Swing out the mirror.
• To set the correct position, switch on the light localizer
by pressing the height adjustment key ↑ .
The horizontal light beam FH should go through the
lower margins of the orbits and the upper margins of
the external auditory orifices (Frankfurt Horizontal
plane FH).
For this reason the FH localizer (9) can be adjusted man-
ually upwards and downwards.
• Ensure that the spine is slightly tilted as described
before.
(Have the patient take a small step toward the column).
• Close temple supports (3) with knob.
• Insert contact spacer F (see page 18) and slide down
until it makes contact with the front.
• Swing back the mirror.
