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 transfer-
bows (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 rests in the notch in the
cross-beam of the support pin.
If Type-I support pins are
used, close articulator until the plane indicator touches
the SME indicator of the transferbow.
6.6.6 Then, orientate mandibular model in the usual manner.
6.7 Personalized setup of anterior guidance
For the fabrication of personalized incisal plates, Ivoclar Vivadent
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, 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 polymeriza-
tion of the resin.
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.
