then a skin would form on the surface) onto the
upper teeth to create slight impressions (the

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.

Fitting the Facebow (arbitrary)

The patient's mouth must always be open
when the facebow is adapted, i.e. after fit-
ting the bite fork to the upper teeth.
The Leipzig nasion incorporates a tele-
scope with a spring that counterbalances
the weight of the facebow when the red
mark is covered by the outer telescope.
Thanks to the standardized, controllable
pressure, the position of the ear adapters
[6]/axis pin [10] in the arbitrary hinge axis
region is reproducible..
Patient in lying position. This counteracts the
weight of the facebow and lever effect of the front
section.
Only loosen the set screws [1] - do not
attempt to un- screw them fully. This also
applies to the clinched collar screw [22] on
the fork mounting, which might jam.
▷ Loosen the set screws [1] and insert the porus
buttons [6] into the patient's auditory canals,
allo wing the patient to assist.
▷ Tighten set screws [1], loosen nasion set screw
[15] (1/4 turn), and gently press the nasion [16]
onto the glabella.
▪ The middle and index fingers are used to grasp
behind the nasion support while the thumb
exerts gentle, continual pressure on it.
▪ The other thumb is used to stretch the fore-
head skin to allow the nasion adapter [17] to
adapt to the bridge of the nose.
▷ When the red mark is covered by the outer tele-
scope, tighten the set screw [15] with your free
hand.
