Three light traces show up on the face as shown in figure 5; the first two
highlight the medial-sagittal plane and the Frankfurt plane; the third highlights
the cusp of the upper canine and is adjusted last.
Patient positioning for lateral TMJs.
Position the patient's head in such a way that the Frankfurt plane coincides
with the horizontal light trace (as shown in figure 4).
You do not need to move the patient's nape to do this.
To adjust the head inclination, just raise or lower the unit using the height
adjustment buttons. The patient's back must be straight.
The horizontal light trace is generated by a laser situated on the X-ray
generator side. It can be adjusted up or down to adapt it to different-sized
heads by acting on the lever located next to the light beam opening.
The light trace should pass from the lower margin of the orbit to the upper
margin of the auditory meatus in such a way that these two points are on the
same horizontal plane, as shown in figure 4.
Close the temple supports. hyperion is equipped with sophisticated temple
supports that are touch-sensitive. Close the supports acting with both hands
on both the left and right side, with your index fingers positioned in
correspondence to the touch-sensitive sensors. The two supports move
independently, which allows compensating cranium asymmetries.
Make sure that the patient looks straight ahead, since even if the trace of the
medial-sagittal plane may seem to be positioned correctly, the head may be
turned slightly to one side.
Keeping the temple supports up against the patient's cranium, move away
your index fingers. An electromechanical brake will lock the temple supports
in place with a noticeable click. At this point, you can move your hands away.
A third laser trace indicates the exact position of the focal ridge of the unit.
For good focus, let this trace match with the position of the condyle (see
figure 4).
If you need to do an examination with the mouth closed, simply act on the
RH/LH offset buttons
the condyle.
When the TMJ examination is selected, the machine by default starts in
"closed mouth" mode (see figure 7a).
