5 Fitting the facebow to a
dentate jaw
5.1 Preparing the facebow
Screw in all the components in advance to prevent
stressing the patient unnecessarily.
▷
Check that the support brackets [5] have been
screwed in firmly (porus buttons pointing
inwards). The screw collar is in the key hole.
▷
Tighten the nasion on the facebow with fixing
screw [14].
▷
Retract the nasion fully and tighten it with set
screw [15].
▷
Insert the universal joint into the front of the
conical support mounting slot [2]. Press it in
fully and tighten it with adapter screw [20].
Toggle screw [23] must be on the right
(patient’s left).
▷
Allow the universal joint to hang down and
tighten toggle screw [23] gently.
5.2 Quickbite single-use bite fork
This newly designed plastic bite fork is covered
with a thermoplastic material. It is used in the
same way as a conventional metal bike fork but
does not require cleaning or disinfection.
5.3 Preparing the bite fork
▷
ttach thermoplastic pellets (
“
Bite Tabs
”
(Art. No.
642150)) on self-adhesive foil to the bite fork at
three locations and place bite fork for about
1 minute in approx. 40
°C
warm water.
▷
The applica- tion of compound on the opposite
side of the bite fork ensures that the compound
does not get loose.
The cranked handle of the bite fork points down-
wards.
5.4 Fitting the bite fork to the patient
▷
Place the prepared bite fork on the upper teeth.
▷
Gently press the warm compound (not too hot,
then a skin would form on the surface) onto the
upper teeth to create slight impressions (the
teeth must not contact the metal fork).
The patient can then hold the bite fork bite fork
in position, either with his/her fingers or with
cotton rolls inserted between the lower molars
and the bike fork.
▷
When using the facebow on the patient,
the screws must only be loosened 1/4
turn. Instead of opening the screws com-
pletely, it is sufficient to loosen them
only slightly. This ensures that they grip
and fix the com- ponents into place
immediately when tightened.

B
Although hard wax or hard silicone may be
used, they are not recommended.
If the curve of Spee is unfavourable, the
bite fork may tilt.
▷
In this case, it is better to hold the bite
fork with a hand rather than cotton rolls.
