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.

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.

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-

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

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.

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.

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.

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.

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. Adapt firmly and create smooth, rounded transitions between the layers using SR modelling instruments and synthetic brushes.

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.

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.

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.

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.

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.

Adoro® – Practical Procedure
for Fixed, Metal-Supported Restorations
Framework Design
The following points must be observed for the design of frameworks for composite veneers:
1. Framework design for full-coverage veneers (ideal space conditions)
With full-coverage veneers, the framework has to reflect the shape of the tooth in a reduced form. Design the framework in such a way that it supports the cusps resulting in a virtually even layer thickness of the veneering composite in the cusp-fissure area. In this way, the masticatory forces occurring during functional chewing are exerted on the framework rather than on the veneering composite. In case of unfavourable preparations, the missing tooth structure has to be com­pensated by the design of the framework and not the veneering composite. Furthermore, an even layer thickness facilitates the creation of a harmonious shade effect while full-coverage veneering provides a maximum level of esthetic beauty and function. All areas of the framework should be smooth and rounded to prevent delamination and cracking. Angles and edges should be rounded out already in the wax-up and not in the metal in order to avoid undermining the minimum framework thickness. The thickness of the metal framework for single crowns must not be less than 0.3 mm and 0.5 mm for bridge abutments after finishing (see diagram).

Premolar crowns
Molar crowns
31
Page 32
2. Framework design for partial veneers (limited space conditions)
A different framework design is required for partial veneers (e.g. telescope and conus crowns). As the space in the occlusal, palatal and lingual area in particular tends to be limited in many cases, this area of the restoration must be designed in the metal in such a way that cracks or delamination cannot occur because of too thin layer thicknesses of the veneering composite. In this design, the transition between the metal framework and the veneering composite should be clearly defined and it should incorporate a right angle finish line. The transition areas between the metal framework and the veneering composite must not be located in the contact point areas, nor on surfaces involved in masticatory functions. A chamfer or wraparound technique is required in partial veneer preparations to provide adequate support for the veneer. Observe the palatal area in upper canines (canine guidance) and the occlusal area in posterior teeth. To obtain a balance between esthetic and functional properties, it is advisable to reduce the medial corner of the occlusal surface in upper posterior teeth in particular to attain a harmonious esthetic appearance, especially when the buccal corridor is exposed. The thickness of the metal framework for single crowns must not be less than 0.3 mm and 0.5 mm for bridge abutments after finishing (see diagram).
For further information, please refer to the Instructions for Use of the corresponding alloy.

Premolar crowns
Molar crowns

3. Design of bridge pontics
Bridge pontics are designed taking esthetic and functional aspects as well as oral hygiene into consideration. The area of the pontic that contacts the alveolar ridge should be made entirely of metal (polished to a high gloss) or composite. The transition between the metal and composite should always be located in an area where efficient oral hygiene is ensured. If adequate space is available, the contact area is made of composite. In order to ensure adequate stability between the bridge pontic and bridge abutment, a palatal and/or lingual scallop is recommended. If space is limited, the contact area is made of metal burnished to a high gloss. The palatal and/or lingual areas are made of metal to ensure adequate stability. To prevent shrinkage cavities from forming in extensive pontics, it is advisable to hollow out the pontic. A wax wire is placed in the hollowed space (ample space available) and formed in such a way that it is level with the abutment teeth. This measure provides additional retention and helps achieve an even colour effect in the bridge pontic and abutment.
Ideal space available Limited space available
Practical Procedure for Fixed Metal-Supported Restorations
33
Page 34
4. Interface between metal and composite
The interface between the metal framework and the veneering composite must be clearly defined; incorporate a right angle finish line and use a chamfer or wraparound technique. The transition areas between the metal framework and the veneering composite must not be located in the contact point areas, nor on surfaces involved in masticatory functions. Furthermore, make sure that the interface in the marginal area does not come into contact with the gingiva, particularly if a tapered crown margin is used (e.g. no metal margin). In this way, irritation of the gingiva can be prevented. The inter­face in the interdental area should be designed in such a way that cleaning of these difficult-to-access areas is possible.
5. Correct application of retention beads
It is generally advisable to apply retention beads to provide mechanical retention in addition to the chemical bond with SR Link. If space is limited, it may not always be possible to apply retention beads or they may only be applied in certain areas. Therefore, retention beads can be applied locally to the bonding surfaces without compromising the space availa­ble or the esthetic appearance of the restoration in particular. The retention adhesive should be applied in as thin a coating as possible so that the retention beads are not completely immersed in adhesive and enough surface area for mechanical retention is provided. After casting, the retention beads may be reduced by half of their size (equator) to pre­serve a sufficiently large retentive area.

Fabrication of a working model with removable segments and with the sealer and spacer applied.
Framework design
There are two types of frameworks, i.e. frameworks for full-coverage veneers (ideal space) and frameworks for partial veneers (limited space). Basically, it is advisable to design a full wax-up and then fabricate a silicone key to check the space conditions during contouring. When fabricating the frameworks, make sure that the minimum wall thickness after finishing is 0.3 mm for single crowns and 0.5 mm for bridge abutments. These dimensions are the prerequisite for a stable metal framework and a durable bond between the metal and composite. If the stipulated framework and connector dimensions are not obser ved, delamination and cracking may occur.

Casting and Finishing
After having cast the framework (e.g. with Academy Gold XH), carefully divest, sandblast / pickle and fit it on the model. After separating, the metal framework is finished using tungsten carbide burs. If softer alloys are used, it is recommended to work with limited pressure. A correct marginal design is paramount to attaining a reliable composite-metal bond. If possible, create a tapered chamfer or wraparound design in the cervical area.

Conditioning of the Framework

After finishing, carefully blast the framework with aluminium oxide (Al Instructions for Use of the corresponding alloy). Sandblasting improves the mechanical bond. It roughens and thus sub­stantially increases the surface of the object. After blasting, remove blasting medium residue by tapping off and not by cleaning with steam or an air gun. Apply SR Link immediately after having tapped off the residue. Use a clean disposable brush to apply SR Link and allow to react for 3 minutes. Do not "soak" metal surface in SR Link.

Sealing the model
Before building up the Dentin and Incisal materials, all parts of the model that may come into contact with SR Adoro are sealed. This step helps to prevent the composite from sticking to the model. Use SR Model Separator to seal adjoining parts of the model (e.g. stone die and pontic rests). Apply SR Model Separator in a thin layer, allow to react for a short time, and remove excess with oil-free compressed air.

It is advisable to apply Deep Dentin of the next brighter shade or highly opaque pastes, e.g. Mamelon light, to the pontic rest to ensure adquate shade stability. After that, layer these areas using Cervical, Deep Dentin and/or Dentin materials.
It is recommended to build up the veneer segment-by-segment (tooth-by-tooth) and separate from each other and then to precure. Finally, the individual veneers are joined.
Opal Effect pastes provide a true-to-nature opalescent effect in the incisal third. Opal Effect 1 is applied to the cut-back dentin as extension of the dentin core and then precured. Opal Effect 5 is suitable to create secondary dentin.
Use the shaded Transpa materials to complete and enhance the vitality in the incisal area. Transpa blue is suitable for the mesial and distal aspects.
Use Mamelon materials to create a lifelike shade effect in the incisal third. They are applied on the completed incisal area. Create smooth transitions. Avoid edges, since they may look like stubs after polymerization and the mamelons may appear too pronounced.

Dentin / Incisal layering
The layering procedure of the individual SR Adoro pastes is carried out in accordance with the layering diagram (shade guide layering). Adapt the first layer firmly (press into place) to ensure an effective bond between the composite and the opaquer surface and precure each segment for 20 seconds using a Quick curing light. Cervical or Deep Dentin material may be applied in a half-moon shape to cervical areas, pontics and crown margins that are thinning towards the metal. Adapt firmly and create smooth, rounded transitions between the layers (Cervical – Dentin – Mamelon – Incisal) using SR modelling instruments or synthetic brushes.
Stabilize the pontic area with Deep Dentin and apply Cervical material in a half-moon shape in the cervical area.
After that, build up the dentin layers step by step and precure each segment for 20 seconds. The shade effect in the interdental area may be enhanced by means of chromatic materials, such as Occlusal Dentin orange. Design the dentin core in such a way that the mamelon shape remains outlined. Make sure to provide adequate space for the subsequent application of the Incisal and Transpa materials. The mamelons can be individually designed with either Mamelon material or SR Adoro Stains. After that, the restoration is completed layer by layer using Incisal and Transpa materials. The coordi­nated consistency of the material ensures that modelled contours are maintained and enables easy layering. The Incisal materials are coordinated with the Dentin materials so that delicate transitions can be designed. Subsequently, precure each segment for 20 seconds using the Quick.
Practical Procedure for Fixed Metal-Supported Restorations
Apply the first layer on the Opaquer firmly, build up step by step, and precure.
– 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.

Final Polymerization / Tempering
Preparing for final polymerization / tempering
It is imperative to observe the following steps when preparing metal-supported SR Adoro restorations for final polymerization / tempering:
Step 1 – Applying SR Gel
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. Apply SR Gel on the entire veneering surface ensuring that all areas are fully covered and the layer is not too thick to prevent the formation of an inhibited layer.
If necessary, precure one more time and apply a fully covering but not inappropriately thick coat of SR Gel.
50
Page 51
Step 2 – Applying SR Adoro Thermo Guard
Once SR Gel has been applied, cover all exposed metal parts with SR Adoro Thermo Guard. Open SR Adoro Thermo Guard syringes only immediately before use to prevent admission of air. Quickly start by filling the internal aspects and/or basal surface of the crowns and then cover the exposed metal parts, such as scallops, occlusal surfaces and margins, and smooth out SR Adoro Thermo Guard. Ensure homogeneous application and thorough wetting of the metal. Prevent large amounts of SR Adoro Thermo Guard on the veneering surfaces. Close syringes immediately after use, position the restoration on the object holder and polymerize / temper in the Lumamt 100 or Targis Power Upgrade.

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.

High-gloss polishing
The restorations are polished to a high gloss using a goat hair brush, cotton or leather buff, as well as Universal Polishing Paste. Use low speed and limited pressure for high-gloss polishing. Adjust the pressure with the handpiece, not the polishing motor. In order to optimally polish the interdental areas and occlusal surfaces, we recommend modifying the goat hair brushes to become star-shaped 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 buffs are used to achieve a lesser degree of lustre.

Adoro® – Practical Procedure
for Framework-Supported Combination Dentures
Procedure for Combination Dentures
In combined denture prosthetics, the composite veneer is the measure of choice. Depending on the type of polymeriza­tion process, different working procedures apply. SR Adoro veneers can be fabricated in two different ways and can therefore match every working procedure in the dental laboratory. Ivoclar Vivadent recommends Version A, as this method prevents the denture saddle from being exposed to excessively high temperatures.
Variant A: Veneering with SR Adoro BEFORE setting up and completing the denture saddles
1. Fabricate the primary and secondary components (e.g. telescope crowns)
2. Fabricate the model casting (transversal connector, sublingual saddle bar)
3. Connect the secondary components with the model casting by adhesive joining, soldering, or laser technique.
4. Veneer the secondary components with SR Adoro.
5. Polymerize / temper, finish and polish the SR Adoro veneer.
6. Mask the retentions of the model casting with SR Adoro Gingiva Opaquer.
7. Set up and complete the denture with denture base material (e.g. ProBase Cold).
Variant B: Veneering with SR Adoro AFTER setting up and completing the denture saddles
1. Fabricate the primary and secondary components (e.g. telescope crowns)
2. Fabricate the model casting (transversal connector, sublingual saddle bar)
3. Connect the secondary components with the model casting by joining (adhesive joining), soldering, or laser technique.
4. Mask the retentions of the model casting with SR Adoro Gingiva Opaquer.
5. Set up and complete the combination denture.
6. Veneer the secondary components with SR Adoro.
7. Completely cover the denture saddles and teeth with SR Adoro Thermo Guard because of the polymerization/ tempering temperature of 104 °C (219 °F). All resin areas must be entirely covered.
8. Polymerize / temper, finish and polish the SR Adoro veneer.

Shade Matching of SR Adoro to Denture Teeth
In combined denture prosthetics, matching the shade of composite veneers and denture teeth is very important. The SR Adoro materials and the specially developed cervical materials permit efficient shade matching.

The layering procedure of the individual SR Adoro pastes is carried out in accordance with the layering diagram for the Chromascop shade guide. Adapt the first layer firmly (press into place) to ensure an effective bond between the composite and the opaquer surface and precure each segment for 20 seconds using a Quick curing light. In the cervical area, build up Deep Dentin in a half-moon shape to stabilize the shade. Create smooth and rounded transitions between the individual layers (Deep Dentin – Dentin – Incisal) using the SR Modelling Instruments and synthetic brushes. After that, build up the dentin layers step by step and precure each segment for 20 seconds. Design the dentin core in such a way that the mamelon shape remains outlined. Make sure to provide adequate space for the subsequent applica­tion of the Incisal and Transpa materials. After that, the restoration is completed step-by-step using the corresponding Incisal materials. Subsequently, precure each individual layer for 20 seconds per segment using the Quick curing light.
The basic working procedure (contouring, casting, finishing, framework conditioning, opaquer application,
etc.) and the removal of the inhibited layer are carried out as described on page 31 for crowns and bridges.

Apply Cervical material in a half-moon shape and spread out to a thin layer using SR Modelling Instruments and synthetic brushes. The Cervical material is not covered with Dentin. After that, build up the Dentin material step by step and precure each segment for 20 seconds. Design the dentin core in such a way that the mamelon shape remains outlined. Make sure that the marginal ridges in the dentin are positioned slightly more to the back compared to the Chromascop layering method. After that, the restoration is completed step by step using the corresponding Incisal materials. Subsequently, precure each individual layer for 20 seconds per segment using the Quick curing light.

After finishing the model casting, carefully blast the retentions with aluminium oxide (Al (44 psi) pressure (see Instructions for Use of the corresponding alloy). Sandblasting improves the mechanical bond. It roughens and thus substantially increases the surface of the object. After blasting, remove blasting medium residue by tapping off and not by cleaning with steam or an air gun. Apply SR Link immediately after having tapped off the residue. Apply SR Link with a clean disposable brush and allow it to react for 3 minutes. Do not "soak" metal surface in SR Link.

Starting Situation / Layer Thickness / Framework Design
Starting situation
Fabricate a working model with removable segments as usual. The directions of the manufacturers of the different CAD/CAM systems regarding the plaster to be used must be observed.
Important for die preparation: – Check the radius of the incisal/occlusal edge on the
prepared dies (maxilla and mandible).
– The prepared incisal edge should be at least as thick as
the diameter of the bur used in the cavity during the CAD/CAM process.
– If the incisal edge of the prepared die is thinner than the
diameter of the bur, the incisal edge has to be blocked out accordingly.
– Also observe the information provided by the
manufacturer of the CAD/CAM system regarding the die geometry.
– Basically, only frameworks and implant superstructures of
yttrium oxide, partially stabilized, sintered, or HIP zirconium oxide in a CTE range of 10.5–11.0 x 10
-6 K-1
(100–500 °C) may be fabricated.
A model with detachable segments is used as the basis
Framework design
The framework reflects the reduced anatomical tooth shape (see page 32 for tooth shape-supporting contouring). As a result, the composite can be applied in an even layer and will consequently be appropriately supported. The requirements of the different alloys have to be taken into account.
Framework design
Design the framework in a reduced supported shape.

Framework Preparation / Conditioning
Framework preparation
The stipulations of the manufacturer of the zirconium oxide regarding framework fabrication and preparation for veneering must be observed. When using, for example, IPS e.max ZirCAD, please observe the notes on finishing and regeneration firing in the respective Instructions for Use. The completely sintered zirconium oxide framework is fitted on the model. Do not shorten the cervical margin to the inner edge of chamfer or shoulder preparation (see image of the premolar).
Please observe the following procedure: – Make sure that the minimum framework thickness is maintained even after minor adjustments. – Check marginal areas and slightly finish, if necessary. – Do not “post-separate” the bridge framework with separating disks after sintering, since this may result in
predetermined breaking points, which will subsequently compromise the stability of the restoration.
– Thoroughly blast the framework with Al
(15 psi) pressure. – Only tap off any residue; do not blast or rinse with water to clean the framework. – The framework must be free of dirt and grease. Any contamination after cleaning must be prevented.
Sandblasting improves the mechanical bond. After blasting, remove blasting medium residue by tapping off and not by cleaning with steam or an air gun.

Adoro® – Practical Procedure
for Restorations with Gingiva Components
The shades of SR Adoro Gingiva are coordinated with those of the Ivoclar Vivadent Gingiva concept of IPS InLine, IPS d.SIGN and IPS e.max Ceram. 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. Especially in implant prosthetics and in conjunction with metal-ceramic restorations, the use of SR Adoro permits an efficient treatment concept. Given the polymerization in the Lumamat 100 light furnace, the shape and shade of the gingiva components may be modified quickly and without any additional heat treatment.
Gingiva shade determination
Five Gingiva shades (G1–G5), 4 Intensive Gingiva materials (IG2–IG4), as well as one SR Adoro Gingiva Opaquer (pink) are available for the design of the gingiva components. For the individual determination of the gingiva shade / characteristics, a shade guide of the various Gingiva materials is available.
Framework Design
Framework design criteria
The portion to be veneered with Gingiva material has to be included into the contouring of the framework. Make sure that the transition between the framework and SR Adoro is not located on the contact surface to the mucous membrane. Ideally, the contact surface is entirely designed in metal or in composite. Always ensure adequate hygiene capability.

Framework preparation for the metal-ceramic and the gingiva components
To provide additional support for the framework, the ceramic opaquer is applied on both the area of the veneer and the gingiva components (Gingiva Opaquer). The bond between the metal-ceramic surface and SR Adoro is generated with the help of a silane bond preceded by surface conditioning. The application of SR Adoro Gingiva on the ceramic surface consists of 3 steps.

Activating the ceramic surface
1. Condition the ceramic surface by blasting it with Al
O3 (2 bar / 29 psi, 100 microns) or etching it with IPS Ceramic
2
Etching Gel. The reaction time of IPS Ceramic Etching Gel is 60 seconds.
2. Then, apply Monobond Plus and let it react for 60 seconds.
3. Apply Heliobond in a thin layer immediately after that, disperse with compressed air, and cure for 60 seconds with the Quick.
Application of Monobond Plus and Heliobond.
Note: Blast or etch only those surfaces that are
subsequently veneered with SR Adoro.
SR Adoro Step by Step
Application of the SR Adoro Gingiva materials
Once the veneering surface has been conditioned, directly commence with the application of the SR Adoro Gingiva materials in accordance with the individual shade selection. Given the different gingiva thickness, blood circulation, and pigmentation, the gingiva exhibits different shade effects. These effects have to be translated with SR Adoro. The individual layering of the different Gingiva shades enables a highly esthetic appearance to be achieved.

Start with the more intensive gingiva shades (Intensive Gingiva) applied on the fired opaquer to achieve the correspond­ing in-depth effect. Towards the surface, lighter, more transparent materials provide for a lifelike appearance. Subsequently, precure each individual layer for 20 seconds per segment – using the Quick curing light.

Final Polymerization / Tempering
Apply SR Gel on the entire veneering surface ensuring that all areas are fully covered and the layer is not too thick to prevent the formation of an inhibited layer before polymerization / tempering in the Lumamat 100 or Targis Power Upgrade with light and heat at 104 °C (219 °F). The final finishing of SR Adoro Gingiva is limited to minor adjustments of shape and polishing of the surface.

Finishing / Polishing
Rubber polishers are used for prepolishing and silicone polishing wheels to smooth the surface. High-gloss polishing is performed with a goat hair brush, cotton or leather buff, as well as Universal Polishing Paste.
The result is an individual, lifelike gingiva created without any additional thermal stress to the alloy and the veneering ceramic. Adjustments of shade and shape of the gingiva components are thus possible at any time. It goes without saying that this technique can also be used for all popular Ivoclar Vivadent metal-ceramic materials, such as IPS d.SIGN and IPS Classic.

Subsequent Adjustments
Subsequent adjustments after final polymerization / tempering in the laboratory
If subsequent adjustments are necessary (after 25 min of polymerization / tempering), there are 2 options.
Version A: Adjustments with SR Adoro Add-On
1. Roughen the areas to be supplemented with a tungsten carbide bur or carefully blast with Al
2 bar (29 psi) pressure. Sandblasting improves the mechanical bond. It roughens and thus substantially increases the
surface of the object.
2. Remove jet medium residue with oil-free compressed air after blasting.
3. Do not apply any connector or bonding liquids on the blasted surface.
4. Build-up the necessary supplements using SR Adoro Add-On materials immediately after sandblasting and precure
for 20 seconds per segment with the Quick.
5. Coat the entire veneer with SR Gel.
6. Place the restoration on the object holder.
7. Polymerize the restoration in the Lumamat 100 or Targis Power Upgrade using Program 2 (11 minutes).
8. After polymerization, remove SR Gel under running water.
9. Finish and polish the restoration as described before.
Version B: Adjustments with SR Adoro Dentin and Incisal materials
1. Roughen the areas to be supplemented with a tungsten carbide bur or carefully blast with Al
2 bar (29 psi) pressure. Sandblasting improves the mechanical bond. It roughens and thus substantially increases the
surface of the object.
2. Remove jet medium residue with oil-free compressed air after blasting.
3. Do not apply any connector or bonding liquids on the blasted surface.
4. Build-up the necessary supplements using SR Adoro Dentin and Incisal materials immediately after sandblasting
and precure for 20 seconds per segment with the Quick.
5. Coat the entire veneer with SR Gel and cover the exposed metal parts with SR Adoro Thermo Guard.
6. Place the restoration on the object holder.
7. Conduct final polymerization / tempering in the Lumamat 100 or Targis Power Upgrade using Program 3
(P3, 25 minutes).
8. After completion of the polymerization / tempering procedure, completely remove SR Adoro Thermo Guard from the
restoration using running water.
9. Finish and polish the restoration as described before.

General Information
– Use SR Adoro Add-On only for small supplements, such as pontic rests and contact points.
– Do not use SR Adoro Add-On for surface-covering layers. – Take note of the limited processing time of SR Adoro Add-On.
Subsequent adjustments in the dental office
If subsequent adjustments are required, this can be carried out with a microfilled restorative composite of the Heliomolar group. For this purpose, microfilled composites are better suited than glass-filled composites.
Adjustments with Heliomolar
1. Roughen the area to be supplemented using a finishing diamond (80–100 microns) and carefully clean without water.
2. Apply Heliobond immediately after cleaning and disperse to a thin film with compressed air.
3. After that, apply Heliomolar and cure for 15 seconds with a polymerization light (e.g. bluephase
®
).
4. Build-up the missing areas generously with Heliomolar and cure for 15 seconds with a polymerization light (e.g. bluephase).
5. After polymerization, remove excess using suitable finishers.
6. Polish with Astropol® or OptraPol® NG. Make sure to observe the individual polishing steps so that a smooth surface with a high gloss can be achieved.
– Please read the corresponding Heliomolar Instructions for Use.
– Cleaning pastes that are used after oral hygiene measures must not be used on SR Adoro restorations, since
they roughen the surface and result in loss of gloss.

Questions and Answers
What is SR Adoro Thermo Guard?
SR Adoro Thermo Guard is a diethylene glycol- and water-based paste. The paste, which is applied to all exposed metal parts, provides a thermally absorbing (cooling) effect, thereby minimizing the internal tension at the interface between metal and SR Adoro.
For what restorations does SR Adoro Thermo Guard have to be used?
SR Adoro Thermo Guard has to be used for all metal-supported restorations. Additionally, SR Adoro Thermo Guard is used in combi­nation dentures to cover the resin saddles, as well as for the repair of metal-supported restorations.
Does SR Adoro Thermo guard also have to be used for veneered zirconium oxide frameworks?
No. SR Adoro Thermo Guard has to be used for all metal-supported restorations.
How can hairline fractures in composite restorations be prevented?
Always observe the curing depths, build up in small increments, and always observe the indicated precuring times. Separate the bridge units in the proximal areas, similar as with other light-/heat-curing and heat-/pressure-curing veneering composites. If such hairline fractures develop nonetheless, they can be repaired in the usual manner as described in the section on "Subsequent Adjustments".
Why does SR Adoro Thermo Guard have to be used?
SR Adoro is not a purely light-curing, but a light-/heat-curing veneering composite. Only through tempering with light and heat (thermal treatment) does SR Adoro obtain its optimum material properties and surface quality. Due to the high tempering tempera­ture of 104 °C (219 °F), the CTE values, e.g. of the ceramic, play a decisive role. The CTEs of composite and alloy strongly differ (alloys: approx. 13.5 –16.5 x 10
-6
/K; SR Adoro: 60 x 10-6 /K). The method with SR Adoro Thermo Guard enables even heating, tempering and cooling phases during the tempering with light and heat. In this way, the risk that microscopic hairline fractures develop is reduced.
What is the action principle of SR Adoro Thermo Guard?
With the application of SR Adoro Thermo Guard on all exposed metal parts, the metal cannot heat up to the same extent as the ambient temperature and the veneering composite itself. The heat­dampening (cooling) effect of SR Adoro Thermo Guard helps minimize internal stress at the interface between the metal and SR Adoro. This, in turn, reduces the risk of hairline fractures.
What happens if SR Adoro Thermo Guard is not used?
If it is not used, even heating, tempering and cooling phases do not take place due to the different CTE values of the materials as well as the different heat conductivity (metal = good heat conductor, composite = poor heat conductor and/or insulator). Stress may occur, which may manifest itself after light/heat tempering or later. This may result in microscopic hairline fractures.
For what other purposes should SR Adoro Thermo Guard be used?
SR Adoro Thermo Guard is used to cover denture saddles during the completion of combination dentures as well as repairs. SR Adoro Thermo Guard protects denture saddles (thermoplastic) and denture teeth from deformation during light/heat tempering in the Lumamat 100 or Targis Power Upgrade.
What are the connector dimensions for metal-supported bridges?
The connector dimensions for bridges must be at least 3 x 3 mm.
How must SR Link be stored?
Store SR Link in the refrigerator (2–8 °C / 36– 46 °F).
On what alloys can SR Link be used?
– On alloys that contain up to 90% gold, palladium and platinum – On alloys that contain up to 50% copper and/or silver – On base metal alloys – On titanium alloys
Can SR Link be used on high- gold and copper-free bio alloys and electroformed (galvano) frameworks?
Given the high precious metal content (Au, Pt, Pd, Ag) of bio alloys and the fine gold content (99.9%) of galvano frameworks SR Link cannot be used.
Does SR Adoro Thermo guard also have to be used for the repeated tempering of metal-supported restorations?
SR Adoro Thermo Guard has to be applied before every final and repeated tempering cycle of metal-supported restorations for 25 minutes at 104 °C (219 °F) in the Lumamat 100 or Targis Power Upgrade.
86
What needs to be given particular attention during blasting (conditioning)?
A grain size of 80–100 microns for the Al
O3 has to be used. The
2
blasting pressure depends on the alloy used. Use max. 1 bar (15 psi) for ZrO2 frameworks.
Page 87
Can SR Adoro pastes (high viscosity and low viscosity) be mixed with each other?
High- and low-viscosity materials must not be mixed with each other because they would develop bubbles. SR Adoro must not be processed or mixed with other veneering materials.
What are the layer thicknesses permitted for SR Adoro?
A layer thickness of 2 mm in the incisal and occlusal area must not be exceeded.
Can SR Adoro Stains be applied on the surfaces?
SR Adoro Stains must also be covered with layering materials, such as Incisal and Transpa materials.
Are the connector and bonding liquids required for subsequent adjustments?
Connector and/or bonding liquids must not be used since they minimize the bond of SR Adoro.
In which furnaces can SR Adoro be polymerized / tempered?
SR Adoro can only be polymerized / tempered in a Targis Power Upgrade and a Lumamat 100.
Can the restorations be polymerized / tempered on the model?
The following basic rule applies: The less mass in the furnace (on the object holder), the more targeted polymerization / tempering will be executed. Therefore, it is recommended to remove the adjoining model components from the model before the polymeri­zation / tempering of metal-free restorations to reduce the mass. For metal-supported and zirconium-supported restorations, only ever mount the object on the object holder, if possible. The maximum weight of the working model must not exceed 400 g (corresponds with a large working model incl. Splitcast base block).
Does the colour of the stone (e.g. blue, brown, white, etc.) influence the polymerization / tempering of SR Adoro?
Stone colours do not influence polymerization / tempering. Hence, any colour stone can be used.
Can intermediate polymerization be conducted?
Yes, with Program 2, intermediate polymerization may be conducted for e.g. the Dentin layering (with the use of SR Gel). After that, cut back the restoration and thoroughly clean it before renewed layering (do not blast). Do not use any bonding and/or connector liquids.
General Information
What happens if the curing depths are not observed?
If the stipulated curing depths are not observed, the material can no longer be completely polymerized / tempered, which may result in delamination.
What distance to the light emission window of the Quick initial curing light must be observed to precure the segments?
The smaller the distance between the light and the objects, the more thorough the polymerization of the material will be. The distance must not exceed 2 cm.
Does SR Gel always have to be used?
For the tempering of SR Adoro in the Targis Power Upgrade or Lumamat 100, SR Gel must always be used. If this is not done, the inhibited layer will be too thick, which may lead to clinical failure.
Can working models with plastic base blocks be used?
We advise against the use of such model systems due to the poly­merization / tempering temperatures of 104 °C (219 °F).
How can it be checked if the polymerization/tempering temperature of 104 °C (219 °F) has been reached?
Regularly calibrate the light furnace with the Test Set L100. Observe the Operating Instructions
Can the zirconium oxide framework be reused once the SR Adoro veneer has been removed?
Removing SR Adoro and reusing the zirconium oxide framework is not recommended. Removing the veneering composite bears the risk of causing sustained damage to the framework, particularly its surface. This damage may negatively influence the fatigue behaviour and mechanical properties of the framework.
What zirconium oxide materials can be used as framework material?
Basically, only yttrium oxide partially stabilized, sintered, or HIP zir­conium oxide in a CTE range of 10.5–11.0 x 10
-6 K-1
(100–500 °C)
may be used to fabricate frameworks and implant superstructures.
