If you need to do an examination with the mouth open, simultaneously press
and hold down the RH/LH offset buttons
(see fig. 6). The X-ray source will move slightly: in fact, opening the mouth
wide, the patient's condyle moves out of the mandibular cavity and then
forward.
After the movement, the offset indicator on the console display takes on the
shape of an "open joint" (see figure 7b).
At this point, act on the offset buttons to adjust centring of the vertical laser
trace on the condyle head (see figure 8). Ask the patient to hold the jaw still
during exposure.
If you want to return to "closed mouth" mode, simultaneously press and hold
down the two offset buttons for at least 2 seconds (see figure 6).
Patient positioning for Front TMJs (postero-anterior projection).
Position the patient's head so that the horizontal light trace passes from the
upper 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 9.
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.
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 9).
If you need to do an examination with the mouth closed, simply act on the
RH/LH offset buttons
the condyle (see figure 9).
If you need to do an examination with the mouth open, simultaneously press
