6.6 Personalized model transfer with
the UTS transferbow
6.6.1 Return articulator to the initial set position
– See 6. 1 . 1 for description
Remove incisal guide rod (1.2).
6.6.2 Mount the plane indicator (50) instead of the
incisal guide rod (1.2).
6.6.3 Mount bite fork support to the lower frame
(2.2) by means of the instrument carrier.
6.6.4
– Remove nose rest from
the transferbow and
insert support pins
(Type II) (60) from above.
– Insert the UTS into the
locating holes for
transferbows (6. 1 ).
– Using the support pins,
adjust the transferbow so
that it is parallel to the
table top.
– Finally, secure bite fork with the bite fork support.
6.6.5 Mount maxillary
model to the bite fork and
cast. Close the articulator
until the plane indicator
(50) rests in the notch in
the cross-beam of the
support pin.
6.6.6 Then, orientate mandibular model in the usual
manner.

For the fabrication of personalized incisal plates,
Ivoclar offers a special transparent incisal plate. The
plate is made of a MMA-soluble plastic that bonds
with the set-up resin (SR Ivolen). Anterior guidance
plates thus fabricated can always be exactly
repositioned in the Stratos 300.
Procedure
First, mount the
transparent 0° incisal plate.
Then, position the models
of the patient for which the
anterior guidance should
be formed in the
Stratos 300. Subsequently,
60
mix appropriate resin and spread it on the incisal
plate. Finally, simulate the registered masticatory
movements (protrusion, retrusion, laterotrusion) with
the upper frame of the Stratos 300. The movement
patterns will thus be scratched into the resin by the
incisal guide rod and recorded after polymerization
of the resin.
6. Model Orientation in the Stratos 300
Personalized setup of anterior
guidance
The forming of the natural facets should be
done from excursion to centric. Otherwise, the
resin might be forced out of the incisal plate.
Make sure that no vertical increase of
occlusion occurs.
