Chromasit

SR

SR Chromasit is a pressure/heat-curing micro-
filled veneering material. It features excellent
physical properties and provides true-to­nature shade effects. The material therefore
facilitates the fabrication of lifelike composite
veneers.

The consistencies of the various ready-to-use
SR Chromasit veneering materials are
coordinated and compatible with each other.
As a result, SR Chromasit Dentin, Incisal and
the various special compounds can be
layered without intermediate polymerization.

The combination of the SR Chromasit
veneering material with the SR Link or
SR Chroma Link bonding system produces
long-lasting high-quality results.

Indication

– metal-supported crowns and bridges
– fully veneered restorations up to the

second premolar

– metal-supported implant-borne

superstructures
– veneers in combination dentures
– long-term temporaries in combination with

Vectris

Contraindication

– occlusal veneers on molars
– layer thicknesses of less than 1.5 mm in

the occlusal region
– alloys containing more than 50% silver

and/or copper
– alloys containing more than 90% gold,

palladium and platinum
– non-precious metal alloys or titanium with-

out mechanical retention
– bruxism

Important restrictions on
application

If the following advice is not followed, the
success of SR Chromasit restorations may be
jeopardized:
– Do not apply the material in layers thinner

than the stipulated minimum layer
thickness.

– If the polymerization unit is contaminated

(eg lime build-up), the polymerization
temperature may fall below the required
minimum temperature (115–120 °C /
239–248 °F). If the required temperature is
not reached, incompletely polymerized
veneers, which are prone to the formation
of accrection and plaque, may result.

– If used inappropriately, ultrasonic cleaning

fluids may dissolve the resin surfaces
because of their high degree of acidity.

– It is advisable to use a special jet medium

(Al

2O3

) with a grit size of 100 microns at

2 bar pressure for blasting purposes.

– The use of a jet medium with a lower grit

size may result in veneering material
chipping off.

Side effects

Systemic side effects have not been reported
to date. Allergic reactions may occur in rare
cases. Do not use SR Chromasit restorations
in patients with a suspected or known allergy
to any of the material’s ingredients.

Shade selection

The Chromascop shade
guide represents the shade
standard for Ivoclar Vivadent
products. With its logically
arranged shades, the
Chromascop shade guide
permits quick and highly
accurate shade matching.
The 20 shades are divided
into 5 consistently arranged,
detachable shade groups.
After determining the basic

shade group, the correct
shade within that shade
group is selected. The strict
omission of superfluous
effects (eg cervicals,
transparent areas,
pronounced discoloration
of the incisal and dentin
areas, as well as surface
characterization) greatly
facilitates determining the
appropriate shade.

Fabricating the model

Fabricate a stone model with detachable segments according
to the impression.

Fabricating the framework / Contouring

Fabricate a wax framework on the model according to the
requirements of the case in question. The following measures
are indispensable to achieve a long-lasting bond between the
framework and veneer: accurate contouring of the margins,
application of retention wires to the pontics and appropriate
application of micro- and macroretention (eg retention
splinters) on the areas to be veneered.

Prepare a cervical metal margin if possible, or prepare a
chamfer. Flatten out the incisal edge into a chamfer, if
possible. Provide sufficient protection of the incisal edge.

Contouring the pontics

Processing instructions

Make sure to provide sufficient protection of the incisal
edge.

Adequate retention is particular important in the case of fully veneered restorations.

Anatomical modellation with sufficient protection of the incisal edge on the palatal/lingual surface

Use a wax wire to bring the pontics to the same
level.

14

Preparing the framework

After divesting, finish and adjust the metal surfaces to be
veneered as usual.

Framework after casting and sandblasting.

Appropriate application of retention beads is essential to ensure a favourable mechanical bond.

Fitting the copings.

Finishing the framework, particularly the marginal areas.

The retention beads should neither be too close
together nor should they be too wide apart – the

retentive effect would be lost in both cases. If the
Retention Adhesive is not applied appropriately, the reten­tion beads may become submerged and lose their retentive
effect.

Designing frameworks with pontics

It is advisable to bring large pontics (eg upper centrals,
molars) to the same level as the neighbouring crowns by
applying a wax wire in a targeted fashion. This measure
helps to create a harmonious shade effect in bridges which
involve various layer thicknesses.

Before the sprues are attached, apply a thin layer of
Retention Adhesive onto the veneering surface (‘veneering
window’) of the wax model. Let the solvent evaporate for
approximately 30 seconds. Then, carefully apply the retention
beads onto the surface where required.

15

Sandblast the metal framework with aluminium oxide or with
Ivoclar Vivadent Special Jet Medium.

If SR Link is used as the bonding system, remove blasting
residue only by tapping it off or by applying oil-free
compressed air.

If SR Chroma Link is used as the bonding system, the frame­work may be steam-cleaned. Subsequently, dry with
compressed oil-free air.

The surface to be veneered must be clean to produce a bond
at a molecular level. Even invisible traces of dirt may
compromise the bond between the framework and veneer.
Consequently, all traces of dirt and grease must be
thoroughly removed.

Do not touch cleaned surfaces!

The jet pressure is chosen according to the grit size

of the jet medium. We recommend using aluminium

oxide, Type 100 microns, at 2 bar pressure to sand-

blast the framework. The use of a lower grit size

and/or jet pressure may result in the material

chipping off.

After having been fitted to the model, the metal framework is finished.

After having been fitted to the model and completed, the metal framework is sandblasted with aluminium
oxide.

Completed framework fitted on the model.

Use only metals that are resistant to corrosion and
oral conditions.Alloys which have a high silver or

copper content are prone to corrosion in the oral
cavity and we therefore advise against using them, particu­larly if they contain more than 50% silver or copper. Alloys
that have a precious metal content of more than 90%
develop only a limited amount of bonding oxides. They
must therefore not be used.

Please take the alloy manufacturer’s information about the
alloy’s resistance to the conditions in the oral cavity into
account. That information has to be considered to produce a
long-lasting, reliable restoration.

Metal framework after sandblasting and cleaning.

16

Conditioning the metal surfaces with
SR Link or SR Chroma Link

Version 1: SR Link

Application of SR Link

After the framework has been sandblasted (Al

2O3

/
100 microns/2 bar) and cleaned of blasting residue by
tapping it off, SR Link is applied. Apply SR Link with a clean
disposable brush and allow it to react for 3 minutes.

Do not apply SR Link on alloys containing more
than 50% silver and/or copper or on alloys
containing more than 90% gold, palladium or
platinum.

Non-precious metal and titanium alloys require mechanical
retention to provide a long-lasting bond.

Mechanical retention is generally advantageous to
improving the bond between the framework and veneer.

Application of SR Chroma Link

After you have sandblasted (Al

2O3

/100 microns/2 bar) the
framework and cleaned it of blasting residue by tapping it
off, apply a thin coat of SR Chroma Link on the blasted
metal surface. Subsequently, leave to evaporate for 3 to
4 minutes. The opaquer is applied immediately after the
evaporation time.

If SR Chroma Link is used, retention beads must be
applied onto all types of metal frameworks
(precious metal, non-precious metal, or titanium).

Apply a thin coat of SR Chroma Link, using a disposable brush.

Version 2: SR Chroma Link

Apply SR Link.

17

Apply a thin coat of opaquer (wash).

Apply the second opaquer layer, covering the entire metal surface.

Completely opaqued surface.

Leave the opaquer to dry for a few seconds.

Applying the opaquer

Mix SR Chromasit Opaquer with SR Chromasit Opaquer
Liquid to a thick-flowing mixture, using a brush. Cover the
mixture and leave it to swell for approximately 2 minutes.

Then, apply the first coat of opaquer without masking the
framework completely (wash). Make sure to apply opaquer
to all retention areas.

After that, apply another layer of opaquer. This time, the
metal surface should be entirely covered with opaquer. If
necessary, thin the consistency of the opaquer by adding
SR Chromasit Opaquer Liquid.

Mix the opaquer to a thick-flowing mixture, cover
the mixture and leave it to swell for 2 minutes.

To ensure a smooth transition between the metal and
veneering resin, let the opaquer thin out at the metal
margins.

If a smooth surface is required, the opaquer can be
smoothed by applying a vibrating motion for a short time.

Check all critical areas for thorough polymerization, using a
probe.

18

Processing procedure for pontics

Step 1:

Sandblast the completed framework with aluminium oxide,
clean with steam (only if you are using SR Chroma Link) and
dry with oil-free compressed air.

Step 2:

Apply SR Chroma Link or SR Link and allow to dry
(SR Chroma Link: 3 to 4 minutes; SR Link: 3 minutes).
After the drying time has elapsed, apply a thin coating of
SR Chromasit Opaquer to the pontic and build up with
SR Chromasit Dentin until the pontic is at the same level as
the abutment crowns.

Step 3:

Next, apply a masking layer of opaquer to the veneering
areas of the abutment crowns as well as to the pontic,
which has been built up with Dentin. Then, polymerize the
object in the Ivomat (with water) at 120 °C (248 °F) and
6 bar pressure for 5 minutes.

Step 4:

Continue with the veneering procedure.

After having left the opaquer to swell, apply it to the
veneering area and polymerize another time at 120 °C
(248 °F) and 6 bar pressure for 5 minutes.

Polymerizing the opaquer

After applying the opaquer, polymerize the material in the
Ivomat (with water) at 120 °C (248 °F) and 6 bar pressure
for 5 minutes.

The opaqued surface must be free of water. If not, a
separation layer between the opaquer and resin forms. To
prevent such a separation layer from occurring, carefully dry
the opaqued surface with compressed oil-free air before
veneering.

Characterizing the opaquer

Depending on the customary techniques of the technician,
the shade of the standard opaquer can be modified by
adding SR Chromasit Intensive Opaquer. For this purpose, a
small quantity of SR Chromasit Intensive Opaquer is added
to the standard opaquer powder during the mixing procedu­re. Alternatively, mix SR Chromasit Intensive Opaquer with
SR Chromasit Opaquer Liquid and apply the mixture to the
polymerized standard opaquer.

Layering technique

Isolating

Before building up the veneer, isolate all contact surfaces
with the wet plaster model, using Separating Fluid. Remove
excess with oil-free compressed air.

The SR Chromasit materials can be applied either according
to the layering diagram to produce the Chromascop shades
or individually. Make sure to build up the pontic areas
adequately.

SR Chromaist Creative Dentin is applied to achieve special
effects such as characterization of cervicals or proximal areas.
The Dentin and Incisal materials can be layered without
intermediate polymerization.

The Dentin and Incisal Materials can be layered without intermediate polymerization.

21

SR Chromasit Color or SR Chromasit Intensive can also be
used to apply individual characterizations. These materials
can be applied directly to the restoration, using a brush.
Alternatively, they are first mixed with SR Chromasit Dentin
or Incisal and then applied.

Possibilities of customizing SR Chromasit with SR Chromasit Color and SR Chromasit
Intensive during layering

Characterizations are applied to the proximal area (here: Creative Incisal CS21 dove-blue)

Creative Dentin or Dentin which has been modified with SR Chromasit Color is used to create mamelons….

…which are subsequently covered with Incisal or Creative Incisal Material.

Creative Dentin dove-blue or SR Chromasit Color is applied to accentuate the proximal incisal edge.

Fully layered veneer

After applying the characterizations, complete the veneer
according to the layering diagram, using the SR Chromasit
Incisal materials. The contours created in the dentin are
retained owing to the softer consistency of the Incisal
material.

Avoid trapping air when mixing the shades.

…and coat the fully modelled veneer with SR Chromasit Fluid.

Finish the contact points and interdental spaces,…

…surface characterizations,…

… and proximal surfaces.

Remove the fully layered restoration from the model…

Peparing the restoration for
polymerization

Remove the fully layered restoration from the model and add
Incisal material to the contact points. Make sure that the
material is fully adapted in the marginal areas, ie at the
transition between the metal and veneer.

When fabricating a bridge, separate the individual veneers
using a thin implement.

SR Chromasit Fluid forms a separation layer and

should therefore only be applied to surfaces. It
should not be used as a wetting agent to make
shape adjustments with SR Chromasit.

After polymerization, thoroughly remove SR Chromasit Fluid.

Polymerizing the veneer

Polymerize the veneer in the Ivomat (with water) at 120 °C
(148 °F) and 6 bar pressure for 7 minutes.

Finishing

Finish shape and contact points using appropriate grinding
instruments. Make sure to completely remove SR Chromasit
Fluid from the surfaces of the veneer.

Do not use coarse-grained diamonds, coarse burs or similar
instruments, as it is difficult to produce a sufficiently smooth
surface with this type of instruments.

Final polishing

Carefully polish the restoration to a high gloss using a leather
buffer and Ivoclar Vivadent universal polishing paste.

Microscopic projections on finished veneering
surfaces easily pick up deposits. Finishing and
polishing should therefore be performed very
carefully.

Pay particular attention to crown margins, interdental
spaces and surfaces in contact with gingival tissue.

23

Finish the surfaces and then use a soft rubber polisher to
eliminate rough projections. Next, prepolish the restoration
with a goat’s hair brush and Ivoclar universal polishing paste.

Polishing

Prepolishing

As a rule, polishing should only be performed by means of a
handpiece rather than a polishing lathe. This is the only way
possible to polish all parts of the veneer – and in particular
the interdental spaces – properly.

Finish surfaces and then utilize a soft rubber polisher…

… and prepolish with a goat’s hair brush and Ivoclar Vivadent universal polishing paste.

Completed restoration from labial

24

Contraindication

– occlusal veneers on molars
– layer thickness of less than 1.5 mm

Important notes

– If the layer thickness of the crown and the pontic are sig-

nificantly different in the labial region, the shade effect
may be compromised because of the inherent properties
of translucent materials.

– In order as not to compromise the shade effect, the opa-

qued pontic can be characterized with SR Chromasit
Intensive Opaquer and/or built up with SR Chromasit
Creative or SR Chromasit Dentin, which has been modi­fied with SR Chromasit Intensive, so that approximately
the same layer thickness is used on the entire bridge.
After that, the Dentin and Incisal materials are applied as
usual.

– There must be sufficient space between the metal frame-

work and the antagonist (1.5 mm) so that the layering
material can be applied in the required thickness
(1.5 mm). Thinner thicknesses may result in the
material chipping off.

– If the space available is less than 1.5 mm, an occlusal

metal surface should be preferred.

– After completing the restoration, make appropriate grin-

ding adjustments in the articulator, paying particular
attention to the centric and masticatory movements to
prevent inappropriate stresses from occurring.

First, apply the Dentin material to the cervical region…

Apply a coat of SR Chromasit Fluid to the veneering surface and then polymerize.

… after that, contour the labial and lingual aspects and add Incisal material.

Processing instructions for fully
veneered restorations

Preparing the framework

The occlusal space between the metal framework and the
antagonist should be at least 1.5 mm in order to provide
sufficient space for the veneering material. In addition, the
minimum thickness of the metal (0.3 mm) has to be taken
into account.

Condition the framework and apply the bonding system and
opaquer as described on page 17.

Layering technique

Separate plaster surfaces using Separating Fluid. Next, apply
Dentin material, first to the cervical area and after that,
adapt the material in the labial and lingual areas and finally,
adapt the material on the occlusal surface, according to the
layering diagram. Remove the fully layered restoration from
the model and add Incisal material to the contact areas.

Warnings

– SR Chromasit has been designed for use in dentistry.
– Avoid contact of the skin or eyes with uncured material

(pastes). Prolonged or repeated contact of the skin with
uncured material may cause a slight sensitizing reaction
and lead to a sensitization against methacrylate.

– SR Chroma Link, SR Link, SR Chromasit Fluid, SR Opaquer

Liquid and Retention Adhesive contain methyl methacrylate
and solvent. These liquids are easily flammable and irritant.
Keep away from sources of ignition. Do not smoke. Do not
breathe in vapours. Avoid contact with the skin and eyes.
Unpolymerized liquids irritate the eyes, respiratory system
and skin. Sensitization through skin contact is possible.

– Please observe danger signs on the individual primary

packagings and labels.

Cleaning

– Do not clean removable dentures with alkaline or similar

cleaning agents, as they severely corrode the surfaces and
the bonding layer.

– The use of a toothbrush and toothpaste is the best and

simplest way of cleaning removable dentures. If performed
regularly, this cleaning method effectively helps to prevent
the formation of deposits.

Repairs

Repairs in the laboratory

– The veneer to be repaired should be ground with a tung-

sten carbide bur or sandblasted at reduced jet pressure of
1 bar with aluminium oxide, 100 microns, or Ivoclar
Vivadent Special Jet Medium. Next, steam-clean and dry

with oil-free compressed air.
– Then, apply SR Spectrasit Liquid and allow to evaporate.
– Apply the light-curing SR Spectrasit to the prepared

surface.
– Next, apply Spectrasit Gel and polymerize the veneer in the

Spectramat for 5 minutes.
– Then, finish and polish the veneer as described above.

Repairs by the dentist

– The Ceramic Repair Set from Ivoclar Vivadent offers

dentists a comprehensive range of materials and

accessories to repair composite and ceramic restorations.
– Please refer to the Instructions for Use of the

corresponding materials for detailed information.
