5.6 Registering the position of the
upper jaw with the universal
E N
joint
▷ Loosen toggle nut [23] to allow the universal
joint to move freely.
▷ While the patient presses the bite fork firmly on
to the molar region with cotton rolls on his/her
lower jaw or with his/her hand, the dental-care
provider inserts the fork mounting [21] (with the
collar screw and groove pointing upwards) into
the bikte fork handle and firmly tightens the col-
lar screw [22] fully.
The toggle nut should be positioned to the right
(or from the patien's view at left) to allow the
unhindered transfer into the transfer stand (fig-
ures H).
▷ Tighten toggle nut [23] fully by centralizing the
toggle and exerting uniform pressure on both
ends to prevent it from tipping.
▷ Once the position has been registered, loosen
nasi on set screw [15] immediately. Retract
nasion [16] and fix it in place with set screw [15],
holding the facebow to prevent it tipping.
▷ Loosen set screws [1] and open the facebow.
▷ Remove the facebow and registration down-
wards.

nished with 2 - 3 notches (see Centrofix
instructions).

Securing for transport (transfer)

PREFERRED METHOD: Securing the situation
of the upper jaw in plaster for safe transporta-
tion.
This method is also recommended if the
models are to be articulated in the dental
practice. In any case, the position of the
upper jaw should be secured in plaster
directly at the dental practice. The plaster
provides for a solid base. Transfer stand
and transfer table are both stable and can-
not be distorted. The plaster index can be
kept for control purposes and to position
the upper jaw at any time without the
patient being present. Few things can be
carried out incorrectly and, generally
speaking, nothing can be manipulated
falsely. Thus, articulating has considerably
been simplifed.
The method shown here with the magnetic Spli-
®
tex Plate Set is also applicable for articulator
systems with screw-mounted model plates where
the transfer table is screwed to the lower part of
the articulator.
▷ Loosen adapter screw [20] and remove the
▷ universal joint from the facebow.
▷ Insert the universal joint with upper registration
