3.4.2 Mounting the upper face bow
Pull back the glabella support. The retaining straps are
fixed to the face bow. The base of the bite fork is not on
the bow.
The porus knobs of the anatomical face bow are placed
into both ear canals. The patient can actively help here.
The comfortable, painless bow width is fixed on the front
crossbar, with the aid of the clamp screws.
With moderate pressure, the glabella support is carefully
pushed against the bridge of the nose, then lightly
clamped.
The retaining straps are stretched on both sides, then
closed behind the head and fastened with the Velcro
fastener. The porus knobs should now tend to face
dorsal to the ear canal, so that during excursive move-
ments, the lateral condyle is not hindered. The face bow
is checked for comfortable attachment. If necessary, ad-
just the retaining straps and/or the glabella support.
Eliminate folds of skin under the glabella support by
pulling the forehead skin tight and then screwing in the
support.
