2. Safety First
This chapter is particularly important for staff who work with the
apparatus or who have to carry out maintenance or repair work.
2.1 Field of application
The Stratos 300 must only be used for the indications stipulated in
Chapter 3. Further instructions to assure the proper use of the
Stratos 300 articulator are as follows:
–The instructions, regulations and notes in these Operating
Instructions must be observed.
–The unit must be properly maintained (see Chapter 7).
2.2 Health and safety instructions
If the centric rubber
bands are removed
from their retainers
and the centric fixation
lock is open, the upper and lower
frames may be accidentally
separated.
Risk of crushing
between centric
locking catch and
incline support.
3. Product Description
3.1 Functional description
The Stratos 300 is an individually adjustable articulator built
according to the Camper's plane (CP).
The device is suitable to simulate different human jaw
movements. The protrusion angle and the Bennett angle can be
set individually.
Furthermore, a retrusive movement of 35° as well as an
“immediate side shift” are integrated in the Stratos 300.
An activable centric locking system permits the articulator to be
set to a precise, reproducible initial set position and facilitates
separation and connection of the upper and lower frames. Even
when the centric lock is open, the upper and lower frames are still
connected. Only after removing the centric rubber bands from
their retainers can the two parts be separated.
The locating holes for transferbows, automatic centric return and
a non-slip base are all standard equipment. In addition, the
Stratos 300 features a dirt-and-wear-resistant finish.
A wide range of accessories permits the Stratos 300 to meet the
specific needs and requirements of every user.
Therefore, the apparatus can be used in the field of removable as
well as fixed denture prosthetics.
3.2 Indication and contraindication
Indication
The articulator is suitable for the spatial fixation of models for
lab-fabricated reconstructions. The basic equipment permits
simulation of average movement patterns of the human
temporomandibular joint.
Contraindication
No contraindications are known to date provided that
the articulator is used strictly according to the
Operating Instructions.

4.1 Unpacking and checking the contents
Remove the components of the Stratos 300 from their packaging
and check the delivery for completeness.
Stratos 300 basic model:
1 x Stratos 300
1x Incisal plate 0°
1x Incisal indicator
2x Retentive base blocks
1x Plaster protection plate
1x Incline support holder
If certain parts are missing or damaged, contact your local Ivoclar
Vivadent Customer Service.We recommend keeping the original
packaging for possible future transportation purposes.
4.2 Assembly and initial set-up
Incline support holder
The incline support holder enables ergonomic handling of the
articulator. If mounted, it maintains the articulator at approx. a
45° angle. This position permits a superb overview of the model
mounted in the articulator.
Insert the incline support holder (7.2) into the holding device (7.1)
for the incline support holder. If necessary, the incline support
holder can be removed from the apparatus.
Secure the base block (33) to the articulator by means of the GI
knurled screw (2.1).
5.1 Centric position
The Stratos 300 features a precise centric locking system that can
be activated in the following positions:
5.1.1 Centric fixation (4.1) open
This position permits the simulation of jaw movements.
If the rubber bands (4.2) are removed, the two frames can be
separated.

7.1
Stratos 300-BA-d_e.qxd 14.04.2004 8:16 Uhr Seite 10

5.1.2 Centric fixation lock (4.1) closed
In this position, the two frames of the Stratos 300 can no longer
be separated and the articulator is fixed in the centric position.
The centric fixation can be opened by applying slight pressure.
This greatly facilitates handling for the user.
5.1.3 Centric fixation (4.1) locked
To lock the centric fixation completely, e.g. if the articulator has to
be transported, or if no movements are desired, pull the joint axis
into the precisely defined, final position by turning the centric
screw to the right.
Loosen the centric fixation before carrying out
masticatory movements.
5.2 Protrusion
5.2.1 Protrusive movements can be simulated if the centric
fixation (4.1) is open, according to the schematic below. The angle
of the protrusion path can be adjusted to be more acute or flat
(0–60°) by setting the respective protrusion angle.
Protrusion angle:
By loosening the P knurled screw (5.1), the protrusion angle may
be adjusted and fixed with the P angle indicator (5.2).
The set protrusion angle can be read off at the top edge
of the P angle indicator (5.2).

5.2.2 PR stop (9.2) for centric shift
The PR stop permits each condyle to be incrementally advanced
from 0 to 4 mm into a protrusive position.
Loosen the screw for the PR stop (9.1) and move the PR stop (9.2)
into the desired position on the PR scale (9.0). By fastening the
screw for the PR stop (9.1), the position can be fixed.
Important:
In this case, the centric fixation cannot be used.
5.3 Lateral and Bennett movement
5.3.1 Lateral and Bennett movements
The lateral movements can be simulated when the centric fixation
(4.1) is open, according to the schematic below. To perform this
movement, press with your thumb unilaterally on the joint of the
corresponding side.
Bennett angle
By loosening the B knurled screw (3.2), the Bennett angle can be
read off, adjusted and fixed with the Bennett angle scale (3.3).

5.4 Immediate side-shift movement
The ISS screw permits the fixation of the immediate side-shift.
By turning the ISS screw (10.0), the desired distance from the
Bennett flap (3.1) to the joint bolt can be fixed. The distance can
be continuously fixed between 0 and 1.5 mm and read off the ISS
scale (10.2).
5.5 Retrusion
The retrusion screw (9.0) permits the fixation of the retrusive
movements.
To simulate retrusive movements, the centric fixation lock (4.1)
must be open and the screw to fix the protrusive movement (9.1)
loosened. Moreover, the Bennett flap (3.1) must be set to 0°.This
allows retrusive movements to be carried out properly.
The distance may be continuously set from 0 to 2 mm with the
retrusion screw (12.0) and read off the PR scale (9.0).

molars are missing, the first
molars may be used instead.
–Put mandibular mesial
contact area behind the
incisal tip of the symphysis
fork.
–Adjust horizontal guide in
such a way that the rear
edges barely cover the
marked cusps of the second molars and align symmetry.
–The retromolar pads are used as reference points for free-end

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.
