The Composite Veneering System
In view of the versatile application possibilities of veneering composites, we have made it our objective
to develop a universally applicable material system that not only offers a wide variety of design options
for experienced specialists but also constitutes an optimum and economic alternative for first-time users
and all-rounders.
The main thrust of development work on SR Adoro was towards designing a material that offers
optimal physical properties, excellent esthetics, convenient handling properties and ample flexibility.
Particular emphasis was also placed on coordinating the individual components of the SR Adoro system
with each other, as well as with other Ivoclar Vivadent systems (IPS d.SIGN® or IPS InLine®).
Ivoclar Vivadent, who fostered the idea of integrated systems many years ago, has complemented its
product range by introducing SR Adoro. A coordinated range of products encompassing alloys,
ceramics, denture teeth, equipment, cements and composite veneering materials enables dental technicians to fabricate fixed, removable and combination dentures.
At the same time, the range of possible framework materials was extended with SR Adoro. Zirconium
oxide frameworks are an attractive alternative to conventional metal frameworks that may be optimally
veneered with SR Adoro. Furthermore, SR Adoro is ideally suitable if "pink esthetics" is an issue. With
the use of SR Adoro Gingiva materials, it is possible to complete the soft tissue components easily and
efficiently with composite.
The well-balanced assortment – coordinated with the Chromascop and A–D shade guides – and the
various additional assortments, enable users the highly esthetic reconstruction of lost tooth structure
with SR Adoro.

Product Information
Material
This composite is a tried-and-tested veneering system that offers
several advantages over hybrid composite materials with regard to
wear, handling, plaque resistance and surface gloss. This can be
attributed to the high proportion of inorganic fillers in the nanoscale range. Furthermore, the matrix is based on a urethane dimethacrylate (UDMA), which is distinguished for its toughness, which is
higher than that of its predecessors or the frequently used BisGMA.
In order to achieve a non-sticky, homogeneous consistency and a
low-shrinkage system, a special prepolymer was developed, which,
in turn, is based on nanofillers and the new UDMA. The result is a
virtually homogeneous material, which may well be called a microfilled composite.
500 µm
Physical properties of SR Adoro
The inorganic microfillers together with an innovative matrix impart
homogeneous structure to the material. The coordinated ratio
between these two components provides the best physical
properties and promotes a high resistance against discolouration,
plaque accumulation and wear.

Esthetic properties of SR Adoro
Highly esthetic results can be achieved even if a straightforward,
basic layering procedure is used. Even the basic SR Adoro material
exhibits an opalescent effect, which equals that of the natural
tooth. Aspects such as brightness and chroma and/or opacity and
translucency were taken into consideration for the colouration of
SR Adoro. These characteristics are apparent in the individual components and endow the material with its highly esthetic properties.

General notes
As is generally known, composites have to meet different demands
due to country-specific uses.
Composite veneering materials show specific characteristics and
properties and their performance and durability can therefore not
be compared with that of other C&B materials.
The composite restorations may require clinical repair over time,
depending on the situation and the individual case. The restorations
can be repaired by means of microfilled composites, as described in
the section on "Subsequent Adjustments" on page 79.

Working Times
SR Adoro materials are sensitive to light. The working time depends
on the layer thickness, shading and the prevailing light conditions.
Light shades react more quickly than do dark ones. The times listed
below represent mean values at a light intensity of 3000 lux, which
corresponds to the light encountered in a well-lit working space.
Bear the maximum time limit in minds, when extruding the material
from the syringe.

The Product System
Compatibility with Ivoclar Vivadent equipment
The high-performance Lumamat
developed for the fabrication of high-quality composite restorations.
The object holder of the furnace ensures that the SR Adoro restorations are appropriately positioned for optimum polymerization /
tempering so that they can develop their physical properties to the
full. The sensor-controlled Quick can be used for fast precuring
processes. It can also be used for the intermediate polymerization of
other light-curing veneering materials.
Compatibility with Ivoclar Vivadent alloys
All metal-supported restorations involve the veneering of a previously fabricated metal framework. Ivoclar Vivadent offers customers
a wide range of different high-quality alloys, which are purposedesigned for their specific field of application. The selection includes
high gold, reduced-gold and base metal alloys. The SR Link bonding
system provides a sound bond between the metal and composite.

Curing Depths
Given the material's sensitivity to light, the curing depth of
SR Adoro (i.e. precuring with Quick initial light unit) depends on the
shade and, above all, the layer thickness applied. Light and translucent shades cure more readily, as light can penetrate them more
easily than it does darker and more opaque shades. The curing
depths listed below represent values achieved with the Lumamat
100/ Targis Power Upgrade with a precuring step of 20 seconds
using the Quick initial light unit. It is paramount to bear these values
in mind when layering the individual materials.

Compatibility with Ivoclar Vivadent tooth lines
Especially in partial and removable denture prosthetics, the compatibility between denture teeth and composite veneering material
plays a particularly essential role. For this reason, we paid particular
attention to developing a material that
is capable of reproducing the shade
of the Ivoclar Vivadent denture
teeth.
Compatibility with IPS d.SIGN
®
and IPS InLine
®
The shade concept of SR Adoro, the IPS InLine System, as well as
IPS e.max Ceram follows that of IPS d.SIGN. This means that there is
an Opaquer, Dentin, Deep Dentin and matching Incisal materials for
each tooth shade. The shading of the Impulse, Gingiva, and Stains
materials follows that of the IPS d.SIGN, IPS InLine and IPS e.max
Ceram materials so that the additional materials that are independent
of any shade system permit a similarly esthetic appearance.
This allows users to work more efficiently.
Consequently, the processing of
combined restorations is easier and faster
and shade adaptation to existing ceramic
restorations is more efficient.
SR® Accessories
SR Link, 5 ml
SR Link is a metal /ZrO
provides a covalent bond between the metal and
ZrO
frameworks and SR Adoro. SR Link is an easy-
2
to-use and, above all, tried-and-tested bonding system that can be used in conjunction with a wide
selection of alloys and ZrO2 frameworks. The bonding system is suitable for use on frameworks made of
– alloys that contain less than 90% gold, palladium and platinum
– alloys that contain less than 50% copper and/or silver
– base metal alloys
– titanium alloys
– ZrO
2
SR Link must not be used on electroformed (Galvano) frameworks,
as the reactivity of the components partaking in the chemical reaction decreases with increasing contents of precious metal (Galvano,
99.9% fine gold). Consequently, not enough metal-phosphate
bonds are formed.
SR Gel, 30 ml
SR Gel is a glycerine-based masking gel that is impervious to
oxygen. The gel is applied to the restoration before polymerization /
tempering to minimize the formation of an inhibition layer on the
surface of the veneering composite. Consequently, the gel
ensures complete curing of the restoration surface.

SR Adoro Gingiva concept
The shades of SR Adoro Gingiva are coordinated with those of the
Ivoclar Vivadent Gingiva concept of the IPS InLine, IPS d.SIGN and
IPS e.max systems. In this way, the shade design of true-to-nature
gingiva components, particularly in conjunction with implant superstructures, is possible according to the same method with all
veneering systems.
Compatibility with Ivoclar
Vivadent cementation systems
Choose an adequate cementation option from the Ivoclar Vivadent
range. Suitable luting composites or cements are available for both
the adhesive cementation of framework-free restorations and the
conventional cementation framework-supported restorations.

SR Mixing Plate, small
The SR mixing pad and SR mixing plate are used for different
materials. The pad is mainly used to process liquid materials so that
time-consuming cleaning of the plate can be avoided.
By contrast, the plate is used to mix the
composite components. The light-protective
cover of the plate extends the working time
of the materials.
SR Modelling Instruments
A (yellow), B (red), C (blue)
The classic Ivoclar Vivadent modelling instruments for composite
materials, which are provided in a new, user-friendly design, facilitate the adaptation and contouring of composite materials. They are
available with 6 different tips and

The disposable brushes are particularly
suitable for the application of liquid
materials, such as SR Model Separator,
SR Link, and SR Adoro Opaquer.
Disposable Sponges, 50x
The disposable sponges have been
modified to fit into the universal holder.
They are used to remove the inhibition
layer after polymerization of the
Opaquer and Liner.
Cannulas, 10x
These applications can be attached to Liner,
Opaquer and Stains syringes. They help
achieve more accurate dosing and cleaner
application procedures as the extrusion
pressure can be controlled.
Universal Polishing Paste, 100 ml
The SR Universal polishing paste enables quick and efficient
polishing of composite and metal restorations to a high gloss.
The paste is particularly suitable for prepolishing and principal
polishing of SR Adoro veneers.
SR Composiv, 2.5 g
This ivory-coloured bonding paste is the ideal light-curing microfilled
composite to optimize the bond of various resins and composite
materials. The paste is mainly applied
to promote the bond between Ivoclar
Vivadent denture teeth and the
SR Adoro veneering material.
Cannula Caps, 20x
The cannula caps prevent the material from
drying out or polymerizing prematurely while
it is is in the cannula and provide protection
against contamination.
10
Shade Determination
After tooth cleaning, the tooth shade of the non-prepared tooth
and/or the adjacent teeth is determined with the help of a shade
guide. Individual characteristics have to be considered when
determining the tooth shade. If a crown preparation is
planned, for example, the cervical shade should also be
determined. In order to achieve the best possible true-tonature results, shade determination should be carried out at
daylight. Furthermore, the patient should not wear clothes of
intensive colours and/or lipstick.
SR Adoro – Individualized shade determination
It goes without saying that the materials shade guides are an integral part of the SR Adoro product concept. The dentin shade tabs
feature a textured surface and anatomical shape for light refraction
purposes. The other shade tabs are slightly wedge-shaped to take
account of the translucency of the individual materials. All shade
tabs feature a smooth, i.e. untextured, reverse side to assist users in
comparing the shades against the prepared tooth and coloured
cements and adhesives. The smooth side of the shade tabs may be
individually ground to determine the layering. The individual shade
tabs are made of ceramic for reasons of shade stability. They are
fired of specially coloured ceramic materials to ensure that they
comply with the individual SR Adoro materials. As the materials
shade guides have been modelled on the IPS d.SIGN and IPS InLine
system shade guides, the sample holders of the SR Adoro shade
guides are coloured light grey to distinguish them from the shade
guides of other materials.

SR
Adoro® – Practical Procedure
for Framework-Free Restorations
(Inlays/Onlays)
Preparation Guidelines and Minimum Layer Thicknesses
As framework-free SR Adoro restorations are placed using an adhesive cementation method, a toothconserving and defect-oriented preparation technique can be used.
Inlays
Provide a preparation depth of at least 1.5 mm in the fissure area (central fissure). The isthmus width
should be at least 1.5 mm. The walls of the box should be slightly flared. Round out internal line angles
to enable accurate fit of the inlay. Avoid preparation margins in functional or abrasion surfaces. Avoid
proximal contacts areas. Do not prepare slice-cuts or feather edges.
1.5
1.5
Onlays
Allow for a preparation of at least 1.5 mm in the area of the fissures, an isthmus width of at least
1.5 mm and provide 1.5 mm space in the area of the cusps. The shoulder may be prepared with a
chamfer (10°–30°) to improve the esthetic appearance of the transition between the composite and the
tooth. Onlays are indicated if the preparation margin is less than approximately 0.5 mm away from the
cusp tip, or if the enamel is severely undermined.

Starting Situation
Fabricate a master model or a model with detachable segments according to the impression in the usual manner. Expose
and mark the preparation margin. Block out undercuts with blocking out wax or block out resin to ensure that the
restoration can be removed after the polymerization process without damaging the die. Basically, the application of a
sealer is recommended to harden the surface and to protect the stone die. However, the sealer layer must not result in
any changes of the dimensions of the stone die. It is not mandatory to utilize a spacer, as two coats of SR Model
Separator will be applied. If you use a spacer, check as to whether it is compatible with SR Model Separator.
Fabrication of a working model with removable segments. The die is coated with sealer.
Sealing the Dies and Adjoining Parts of the Model
SR Model Separator is applied in two thin coats. Apply the first coat generously and make sure that all areas of the cavity
are well covered. Watch out for sharp edges in particular. Allow the layer to react for 3 minutes. After the reaction time,
apply a second layer in a thin coat, invert the model, and allow to dry for 3 minutes. Additionally, apply SR Model
Separator to adjoining model surfaces that may come into contact with SR Adoro (including counterbite), allow to react
for a short time, and then disperse excess material with oil-free compressed air.
Apply first coat of SR Model Separator generously, watch out for sharp edges, and allow to react for 3 minutes.
Apply second layer of SR Model Separator in a thin coating and allow to dry for 3 minutes in an upside down position.

Liner Application
Procedure for
non-discoloured cavities
– Apply Liner clear to the cavity
walls and the cavity floor (dentin
area) for an optimum chameleon
effect.
– Apply Liner incisal in the margin-
al areas (course of natural enamel) to achieve a harmonious transition between the shade of the
restoration and natural tooth
structure without grey lines.
Procedure for
slightly discoloured cavities
– Mask dark areas using a liner in
an appropriate shade (050-500).
– Coat the remaining portions of
the cavity, except the marginal
areas, with Liner clear.
– Apply Liner incisal in the marginal
areas (course of natural enamel)
to achieve a harmonious transition
between the shade of the restoration and natural tooth structure
without grey lines.
Procedure for
severely discoloured cavities
– Mask the entire cavity, except the
marginal areas, using a liner in a
corresponding shade (050–500).
– Apply Liner incisal in the marginal
areas (course of natural enamel)
to achieve a harmonious transition between the shade of the
restoration and natural tooth
structure without grey lines.
Practical Procedure for Framework-Free Restorations (Inlays/Onlays)
Liner clear
1st Liner layer– 050–500, clear
Extrude the desired amount of the ready-to-use Liner paste from the syringe and spread it out slightly on the mixing pad
using a disposable brush.
First, apply the Liner to the cavity walls and cavity floor in a thin coat and precure each segment for 20 seconds using a
Quick curing light. Make sure to fully cover all areas, as the Liner provides an essential bonding surface to the luting composite. Do not cover marginal areas at this stage (course of natural enamel).
Liner incisal
Liner 050–500
Fully cover the cavity walls and cavity floor with the first Liner coat.
15
Precure each segment for 20 seconds using a Quick curing light.
2nd Liner layer– incisal
After the application of the first Liner layer, apply Liner incisal in the marginal areas so that all cavity surfaces are coated
with Liner. Apply Liner incisal up to the preparation margin in order to ensure a reliable bond between the preparation
margins and the luting composite. This measure helps to reduce premature discolouration between the restoration
margins and tooth structure.

– The entire inner surface of the restoration has to be covered with SR Adoro Liner. The layer
thickness should be at least 150 microns. Thin out the Liner towards the preparation margin.
– Do not detach hardened SR Adoro Liner from the die, as the layer may become deformed or
break in the process.
– If desired, the translucency of the Liners 050-500 may be increased by using Liner clear or Liner
incisal.

Removing the Inhibition Layer
Thoroughly remove the resulting inhibition layer using a disposable sponge (do not use a solvent); make sure that the
Liner surfaces are free of residue and exhibit a mat finish.
Thoroughly remove the inhibition layer with clean disposable sponges.

17
Inlay / Onlay Layering
Adapt the first layer firmly (press into place) to ensure an effective bond between the Liner and composite and precure
each segment for 20 seconds using a Quick curing light. The shade effect in the interdental area and cavity may be
increased by means of Occlusal Dentin orange. Slightly emphasize the marginal ridges and cusps with Deep Dentin.
Subsequently, begin the process of building up the cavity with Dentin materials. Make sure to provide adequate space for
the subsequent application of Incisal and Transpa materials. The translucency of the restoration may be increased by
means of coloured Transpa materials, such as Transpa orange-grey and Transpa brown-grey. Layer SR Adoro layering
materials step by step and precure each individual layer. After building up and precuring the dental plateau, apply
characterizations with SR Adoro Stains and precure for 20 seconds. Next, complete the restoration using Incisal and
Transpa materials. The cusp tips and triangular ridges may be supplemented with a fine layer of Opal Effect 3 and 4.

– It is essential to observe the stipulated curing depth and maximum layer thickness of the
individual materials during the layering procedure.
– If the maximum layer thickness is exceeded, break up large portions into several increments and
precure each increment for 20 seconds.
– SR Adoro Stains have to be coated with layering material (e.g. Incisal, Transpa).

Polymerization / Tempering
Preparing for polymerization / tempering
After the layering procedure has been completed, all layers must be precured. To make sure that this is the case precure
each segment for 20 seconds using a Quick curing light. Next, apply SR Gel on the entire veneering surface ensuring that
all areas are fully covered and the layer is not too thick.
If necessary, precure one more time and apply a fully covering but not inappropriately thick coat of SR Gel.
General notes on polymerization / tempering
After the application of SR Gel, mount the restoration on the object holder and place it in the Lumamat 100 or Targis
Power Upgrade furnace in the correct position. The following points must be observed for polymerization / tempering:
– 2 programs (P1 and P3) are available for polymerizing / tempering SR Adoro restorations with and without model.
– Framework-supported SR Adoro restorations are permanently polymerized / tempered without model dies and without
model using Program P3.
– Framework-free SR Adoro restorations are permanently polymerized / tempered on the model dies without model base.
If up to 3 restorations are permanently polymerized /tempered together, Program P3 has to be used. For the
permanent polymerization / tempering of more than 3 framework-free SR Adoro restorations, Program P1 is used.
– If SR Adoro restorations are to be permanently polymerized on the model using Program P1 (e.g. bridges), all removable
model components (pontic rests, neighbouring teeth) have to be removed from the working model. The remaining
weight of the working model must not exceed 400 g.

Finishing / Polishing
Finishing
After completion of the polymerization / tempering procedure, completely remove SR Gel from the restoration using
running water and/or a steamer. Carefully remove the restoration from the die while it is still warm. If the restoration is
removed at a later stage, it is advisable to warm up the stone die by means of water vapour. Finish the restoration with
cross-cut tungsten carbide burs and fine diamonds. It is advisable to use low speed and light pressure. Make sure to
rework the entire restoration to remove the inhibition layer of approximately 30 microns from all surfaces. Carefully taper
the margins of the restoration, lightly grind the margins, and adjust proximal and occlusal contact points. Subsequently,
recreate a lifelike tooth shape and surface structure.

Polishing
Prepolishing
Carefully smooth out the ridges on the occlusal surface and proximal surfaces with rubber polishers and silicone polishing
wheels. Pay particular attention to the margins in order to avoid rendering them too short.
High-gloss polishing
The restorations are polished to a high gloss using cotton or
leather buffing wheels, as well as the Universal Polishing
Paste. Use low speed and slight pressure for high-gloss
polishing. Adjust the pressure at the handpiece, not with
the polishing motor.
In order to optimally polish the occlusal surfaces, we
recommend modifying the goat hair brushes to become starshaped so that only the desired areas can be polished due to
the smaller size of the brush.
Depending on the type of high gloss desired, leather buffing
wheels can be used to achieve a high shine, while cotton
buffers are used to achieve a lesser degree of lustre.

Preparation Guidelines and Minimum
Layer Thicknesses
Veneer
If possible, the preparation should be entirely located in the enamel.
Either design a classical preparation with oro-incisal, chamfer-type
embrasure of the incisal edge, or a simple incisal reduction without
embrasure of the incisal edge. Avoid incisal preparation margins in
functional or abrasion surfaces. The minimum preparation thickness
is approx. 0.6–1.0 mm depending on the preparation technique
selected. Dissolution of the proximal contacts is not required.
Discoloured teeth may require more preparation. The extent of the
incisal reduction depends on the desired translucency. The more
translucent the incisal edge of the intended veneer is to appear, the
more pronounced the reduction should be.

SR Adoro Step by Step
Starting Situation
Fabricate a master model or a model with detachable segments according to the impression in the usual manner. Expose
and mark the preparation margin. Block out undercuts with blocking out wax or block out resin to ensure that the
restoration can be removed after the polymerization / tempering process without damaging the die. Basically, the application of a sealer is recommended to harden the surface and to protect the stone die. However, the sealer layer must not
result in any changes of the dimensions of the stone die. It is not mandatory to utilize a spacer, as two coats of SR Model
Separator will be applied. If you use a spacer, check as to whether it is compatible with SR Model Separator.
A master model is used as the working model. Fabrication of a working model with removable segments. The die is coated with sealer.
Practical Procedure for Framework-Free Restorations (Anterior Crowns)
Sealing the Die and Adjoining Parts of the Model
SR Model Separator is applied in two coats. Apply the first coat generously and make sure that all areas of the die are well
covered. Watch out for sharp edges (incisal edges) in particular. Allow the layer to react for 3 minutes. After the reaction
time, apply a second layer in a thin coat, invert the model, and allow to dry for 3 minutes. Additionally, apply SR Model
Separator to adjoining model surfaces (including counterbite), allow to react for a short time, and then disperse excess
material with oil-free compressed air.
Apply first coat of SR Model Separator generously, pay special attention to the incisal edges,
and allow to react for 3 minutes.
Apply second layer of SR Model Separator in a thin coating and allow to dry for 3 minutes in
an upside down position.
Isolate adjoining model parts, as well as neighbouring teeth and counterbite.
25
Liner Application
Extrude the desired amount of the ready-to-use Liner paste from the syringe and spread it out slightly on the mixing pad
using a disposable brush.
First, apply the Liner thinly on the die surfaces. Make sure to fully cover all areas, as the Liner provides an essential
bonding surface to the luting composite. The Liner layer must be at least 150 microns thick and has to be precured for
20 seconds per segment using the Quick.
Apply the Liner on the entire die surface; observe a minimum layer thickness of 150 microns.
TIP
– Liner incisal may be applied to the marginal area to facilitate the transmission of light in the cervical area. This
measure provides a harmonious transition between the gingiva and the restoration.
Procedure for non-vital dies
– Mask the entire die with Liner 050 to block out the dark colour of the underlying tooth stratum and, at the same
time, to attain an adequate degree of brightness.
– Additionally, Stains white or Stains crackliner may be applied locally to the Liner surface to further increase the
degree of brightness.
Liner Apparatus Time Program
Precuring time per
segment
Precure each segment for 20 seconds using a Quick curing light.
Quick 20 s –
– The entire die surface has to be covered with an SR Adoro Liner layer of at least 150 microns. Thin out the
Liner towards the preparation margin.
– Do not detach hardened SR Adoro Liner from the die, as the Liner coping may become deformed or break in
the process.
– If desired, the translucency of the Liners 050-500 may be increased by using Liner clear or Liner incisal.
Removing the Inhibition Layer
Thoroughly remove the resulting inhibition layer using a
disposable sponge (do not use a solvent); make sure that
the Liner surfaces are free of residue. Make sure that the
Liner shows a mat surface.

Anterior Tooth Layering
Adapt the first layer firmly (press into place) to ensure an effective bond between the Liner and composite and precure
each segment for 20 seconds using a Quick curing light. The shade effect in the interdental area and palatal fossa may be
increased by means of Stains orange or Occlusal Dentin orange. Build up the labial surface using various Dentin materials.
Reproduce areas of higher brightness with Opal Effect 3 (cervical) and Inter Incisal white-blue (incisal). Apply the appropriate Transpa materials to the dentin core. Build up and precure the incisal extension using Opal Effect materials (OE 1
and OE 2). Mimic mamelons using Mamelon materials and Stains and precure. Next, complete the restoration step by
step using Incisal and Transpa materials. Build up the palatal ridges using Dentin materials. The triangular ridges may be
coated with a fine layer of Opal Effect 3 and 4. Adapt firmly and create smooth, rounded transitions between the layers
using SR Modelling Instruments and synthetic brushes.
