Exposure occlusal bite block
Intended use:
The occlusal bite block is used for panoramic slice views.
To make patient positioning easier and safer, you can use
the occlusal bite blockfor exposure programs P1, P1 A, P1
C, half-view and full quadrant images, P2, P10 and P12.
The unit here supports the user by displaying correspond-
ing symbols on the Easypad and automatically stopping
and emitting a double-signal when the angle of the occlusal
bite block plate has reached its nominal position.
Preparations:
A replaceable bite block foam (single use device) is used
for the bite impression. This soft bite block foam can also
be used for patients who have no front teeth.
Insert the pins of the upper part in the opening of the bite
block plate, fold the bite block foam down and snap the
lower part onto the pins of the upper part.
Bite block foam (single use device), 100 pcs.

Inserting the occlusal bite block
•
Insert the occlusal bite block in the bite block holder
as shown. The display on the touchscreen now dif-
fers from the usual image.
ATTENTION
The occlusal bite block must be
correctly locked
in
place. The symbol display will change as soon as the
metallic blade
(A)
dips into the coil body.
Check every day whether the arrows
and
the head sym-
bol are displayed consistently. If that is not the case, a
system error is present.
With the occlusal bite block in place, check whether the
green bar is displayed in the head symbol; otherwise a
system error is present.
•
The current head posture is displayed on the right
side of the Easypad touchscreen.
Two green arrows are also displayed.
The left arrow next to the height value indicates
which height adjustment key must be pressed to cor-
rect the head posture.
The right arrow next to the head display shows the
approach to the nominal position.
•
If the occlusal bite block is still inserted in the bite
block holder after an exposure has been taken and
you select any program other than the ones men-
tioned above, the help message
"Change bite
block"
will appear in the comment line.
Then insert the bite block or contact segment re-
quired for this exposure.
The usual display then reappears on the touch-
screen.
The remaining preparation then must be performed
as previously described for the other bite blocks.
