Material

IPS InLine and IPS InLine One are veneering ceramic materials containing leucite. They are suitable for the fabrication of metalceramic restorations at firing temperatures higher than 900 °C (1652 °F). With both products, alloys in the CTE range of

13.8–15.0 x 10-6/K-1 (25–500°C) can be veneered, irrespective of the metal composition. These ceramics are based on leucite-forming glasses, some of which are produced of feldspar raw materials of a natural origin. Given their composition they demonstrate excellent chemical resistance. With the corresponding mixture and targeted heat treatment of these glasses, leucite crystals with a defined grain size distribution are released in the glass matrix. This results in a homogeneous structure for the veneering material, which is not only extremely gentle to antagonist but also provides the high strength and convincing optical properties of the IPS InLine veneering ceramic materials.

PoM – Press-on-Metal ceramic

Material

The IPS InLine PoM ingots are made of a glass-ceramic material containing leucite and based on synthetic glass raw materials, which contain small quantities of an opalescent glass-ceramic in addition to the translucent components. This provides the ingots pressed to full contour with their highly esthetic appearance. The ingots are shaded with pigments, the temperature resistance of which permits the high shade match of the pressed restorations. Both in their pressed and unpressed condition, the ingots demonstrate an iso-tropic structure, which is responsible for its homogeneous distribution of the leucite crystals and the high strength. Another important feature of IPS InLine PoM is its excellent firing stability, which enables the application of Touch-Up materials, Shade, Stains and Glaze without jeopardizing the accuracy of fit of the restoration. The Touch-Up materials are leucite glass-ceramics shaded according to the ingot shade concept. Their thermal expansion and firing temperature are adjusted to suit the application in the cervical area of the ingot after pressing and before the characterization firing cycles.

– If these minimum requirements cannot be observed, cooling to *800 °C, or **700 °C (depending on

the alloy type), is required in conjunction with all main firings and glaze firings.

– With ceramic layer thicknesses of over 1.5 mm up to max. 2.5 mm, as well as with voluminous resto-

rations (e.g. implant-retained reconstructions) in combination with high gold and base metal alloys, cooling to *800 °C or ** 700 °C must be conducted. This also applies to soldered restoratios.

– With alloys in the lower CTE range of 13.8 x 10-6/K at 25–500 °C and the upper range of

14.5 x 10-6/K at 25–500 °C, no ceramic shoulders should be used. With such framework geometries (shoulder) or non-metal-supported areas, the cooling and tension conditions are critical. For ceramic shoulders, alloys in the CTE range of approximately 14.0 to 14.3 x 10-6/K at 25–500 °C are recommended.

– For single restorations – particularly with ceramic shoulders – only the 200g or 300g investment rings

should be used, since the expansion values as well as the cooling and tension conditions are ideally coordinated.

The preparation must provide sufficient space to achieve stable and esthetic metal-ceramic restorations. The usual preparation guidelines for metal-ceramics apply for the IPS InLine System. As usual for metal-supported restorations, dentists may use conventional cementation.

A chamfer preparation is suitable for tapered metal margins. For metal-supported inlays, partial crowns and inlay-retained bridges that are seated using conventional cementation, a chamfer preparation is indicated to minimize the cement gap. The margin is designed in metal. For esthetically pleasing single crowns and bridge abutment crowns, a ceramic shoulder should be provided. For that purpose, a shoulder preparation is required. With adhesive cementation, the margin can be designed in the ceramic. However, the margin should not be bevelled in such cases, since thin, non-metal-supported margins demonstrate a fracture risk.

Framework design criteria

The framework design is key to the success of durable metal-ceramic restorations. The more attention given to the framework design, the better the final results and the clinical success will turn out to be.

1. Functional support of the veneering ceramic

The framework reflects the shape of the tooth in a reduced form. It should be designed in such a way that it supports the cusps and incisal edges resulting in a virtually even layer thickness of the veneering ceramic 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 ceramic. Therefore, the framework must not show any angles and edges (see diagram) so that the masticatory forces do not result in tension peaks, which may cause delamination and cracks. Such angles and edges should already be rounded off in the wax-up, not as late as in the metal. The wall thickness of the metal framework for single crowns must not be less than

0.3 mm and for bridge abutments 0.5 mm after finishing (see diagram). Please refer to the Instructions for Use of the corresponding alloy for further information.

2. Framework design for fired ceramic shoulders

With fired ceramic shoulders, make sure that the framework rather than the veneer is supported by the prepared tooth. The framework is thus reduced exactly to the inner edge of the chamfer or shoulder preparation to achieve functional support of the framework on the preparation. Excellent accuracy of fit on the preparation is essential to ensure that the shoulder material may not reach the inner aspects of the framework during subsequent application.

wrong

3. Framework stability

The dimensions and shape of the interdental connector surfaces significantly influence the stability of the restoration during processing as well as the clinical long-term success after incorporation. Therefore, the dimensions of the interdental connector surface must be designed in accordance with the alloy used (take the 0.2% proof stress into account)! The thermal behaviour of the selected alloy during processing has to be considered when designing the framework.

Single connector width

= single stability

Double the width of the connector

= double the stability

12

Double the height of the connector with single width

= eightfold stability

4. Framework design for bridges

Thermal stress during firing and masticatory forces after cementation affect metal frameworks. These forces must be transferred on the framework rather than the veneer. Particularly in the connector areas between bridge abutments and bridge pontics in bridge reconstructions, the stability must be ensured with the help of the framework design and adequate framework material thickness. The framework design and framework thickness must therefore meet all the optical and functional requirements, as well as the aspects of periodontal hygiene. A full wax-up with the corresponding reduction of the ceramic provides the most predictable results.

During veneering with ceramic materials, the bridge framework is exposed to high temperatures several times. With an inappropriate framework design or insufficient framework thickness, the high temperatures during firing may result in distortion or inaccuracy of fit of the framework. A scallop-type design with e.g. interproximal reinforcements counteracts this development. Additionally, this framework design (e.g. with cooling struts) ensures more even cooling of the restoration during the cooling phase. This is particularly important for high gold alloys.

In order to enable optimum oral hygiene with bridge restorations, the design of the interdental spaces should be given special attention. Adequate opening of the interdental area without creating black triangles should be given special attention in order to ensure proper periodontal hygiene with interdental brushes and dental floss.

5. Design of bridge pontics

Bridge pontics are designed with esthetic and functional aspects as well as oral hygiene in mind. The area of the pontic that contacts the alveolar ridge should be made of ceramic. In order to ensure adequate stability between the bridge pontic and the bridge abutments, a palatal and/or lingual scallop is recommended. Furthermore, to ensure even cooling of the bridge pontic that absorbs the most heat, additional cooling struts are advantageous.

Bridge pontic design – ovate pontic Bridge pontic design – saddle-type pontic

6. Interface between metal and ceramic

The interface between the metal framework and the veneering ceramic must be clearly defined. If possible, incorporate a right angle finish line. The junctures between the metal framework and the veneering ceramic must neither be located in the contact area nor on surfaces involved in masticatory functions. The interface in the interdental area should be designed in such a way that cleaning of these hard-to-reach areas is possible.

Manual

In order not to damage the crown wall during processing, the crown and bridge frameworks are provided with holding pins. They are directly attached to the framework with the help of wax. Dimensions of Ø 0.5–1.0 mm for the holding pins have proven to be useful. They can be used to secure the framework by means of holding clips. Furthermore, the holding pins also act as cooling struts during casting and firing.

IPS InLine One – One-Layer Metal-Ceramic

Important

The holding pins must be placed in such a way that they do not interfere during try-in or in the articulator. They should only be removed without causing overheating once the restoration has been completed.

Please refer to the “Framework Design Guidelines for Metal-Ceramic Restorations” for additional information on framework design. They can be ordered from your Ivoclar Vivadent contact address.

Framework design

Design the framework with a reduced anatomical shape taking the planned layering into account. The wall thickness for single crowns should be at least 0.3 mm and at least 0.5 mm for abutment crowns. Make sure to provide sufficient stability of shape for the framework. Avoid sharp transitions and edges. Design the connector areas between the individual units in such a stable way that they meet the requirements of interdental hygiene and the alloy used.

Design the framework in a reduced supported shape.

1st Dentcisal firing

Isolate the model before layering the Dentcisal material. In this way, the ceramic material is prevented from drying out or sticking to the model. Isolate the stone die and the adjacent areas using IPS Model Sealer. Additionally, separate the area of the pontics with IPS Ceramic Separating Liquid.

Tip:

To achieve an optimum bond between the ceramic material and the opaquer surface, apply a small amount of IPS InLine One Dentcisal material to the cervical and interdental areas (for bridges) and slightly roughen it.

Make sure that the restoration is slightly overcontoured so that the actual tooth shape is achieved after firing. After lifting the bridge off the model, supplement the contact points with Dentcisal materials. Before firing, separate the entire interdental area down to the opaquer.

Tip:

Densify the ceramic surface (after contouring) with a large, dry brush toward the cervical margin before firing.

The ceramic material is applied according to the individual situation. For an optimum firing result, the interdental areas must be separated down to the opaquer.

Individual finishing

Finishing and preparing for the Stains and Glaze firing

Before the Stains and Glaze firing, the restoration has to be prepared as follows: – Finish the restoration using diamond grinders and give it

a true-to-nature shape and surface structure, such as growth lines and convex/concave areas.

– Areas which should exhibit a higher gloss after Glaze

firing (e.g. pontic rests) can be smoothed out and prepolished using silicone disks.

– If gold and/or silver dust was used to visualize the surface

texture, the restoration has to be thoroughly cleaned with steam. Make sure to remove all gold or silver dust in order to avoid any discolouration after firing.

The true-to-nature shape and surface texture are designed.

Stains and Characterization firing

Before the Stains and Characterization firing, the restoration must be free of dirt and grease. Any contamination after cleaning must be prevented. The following steps must be observed: – For better wetting of the stains, IPS InLine/IPS InLine PoM Glaze and Stains liquid may be slightly rubbed into the

surface.

– If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The applica-

tion of too many stains results in an unnatural shade effect. – The cusps and fissures can be individualized using Stains. – The basic chromatic shade is supported with the corresponding Shade material (see table).

Shade adjustment with IPS InLine System Shade and Stains

These stains may be fired in a separate Stains firing. Minor shade adjustments and individual characterizations may also be fired in the Glaze firing. Dispense the desired quantity of IPS InLine System Shade and dilute and mix with IPS InLine System Glaze and Stains Liquid to the desired consistency. Pooling should be avoided and the material must not be applied too thickly. If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The application of too many stains results in an unnatural shade effect.

Framework design criteria

The framework design is key to the success of durable metal-ceramic restorations. The more attention given to the framework design, the better the final results and the clinical success will turn out to be.

1. Functional support of the veneering ceramic

The framework reflects the shape of the tooth in a reduced form. It should be designed in such a way that it supports the cusps and incisal edges resulting in a virtually even layer thickness of the veneering ceramic 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 ceramic. Therefore, the framework must not show any angles and edges (see diagram) so that the masticatory forces do not result in tension peaks, which may cause delamination and cracks. Any sharp angles or edges should be removed in the waxup rather than by grinding the metal framework. The wall thickness of the metal framework for single crowns must not be less than 0.3 mm and for bridge abutments 0.5 mm after finishing (see diagram). For further information, please refer to the Instructions for Use of the corresponding alloy.

Premolar crowns

Molar crowns

27

2. Framework design for fired ceramic shoulders

With fired ceramic shoulders, make sure that the framework rather than the veneer is supported by the prepared tooth. The framework is thus reduced exactly to the inner edge of the chamfer or shoulder preparation to achieve functional support of the framework on the preparation. Excellent accuracy of fit on the preparation is essential to ensure that the shoulder material may not reach the inner aspects of the framework during subsequent application.

correct

wrong

3. Framework stability

The dimensions and shape of the interdental connector surfaces significantly influence the stability of the restoration during processing, as well as the clinical long-term success after incorporation. Therefore, the dimensions of the interdental connector surface must be designed in accordance with the alloy used (take the 0.2% proof stress into account)! The thermal behaviour of the selected alloy during processing has to be considered when designing the framework.

Single connector width

= single stability

Double the width of the connector

= double the stability

28

Double the height of the connector with single width

= eightfold stability

4. Framework design for bridges

Thermal stress during firing and masticatory forces after cementation affect metal frameworks. These forces must be transferred to the framework rather than the veneer. Particularly in the connector areas between bridge abutments and bridge pontics in bridge reconstructions, the stability must be ensured with the help of the framework design and adequate framework material thickness. The framework design and framework thickness must therefore meet all the optical and functional requirements as well as the aspects of periodontal hygiene. A full wax-up with the corresponding reduction of the ceramic provides the most predictable results.

During veneering with ceramic materials, the bridge framework is exposed to high temperatures several times. With an inappropriate framework design or insufficient framework thickness, the high temperatures during firing may result in distortion or inaccuracy of fit of the framework. A scallop-type design with e.g. interproximal reinforcements counteracts this development. Additionally, this framework design (e.g. with cooling struts) ensures more even cooling of the restoration during the cooling phase. This is particularly important if high gold alloys are used.

In order to enable optimum oral hygiene with bridge restorations, the design of the interdental spaces should be given special attention. Adequate opening of the interdental area without creating black triangles should be given special attention when designing the bridge in order to ensure proper periodontal hygiene with interdental brushes and dental floss.

IPS InLine – Conventionally Layered

wrong

29

5. Design of bridge pontics

Bridge pontics are designed with esthetic and functional aspects as well as oral hygiene in mind. The area of the pontic that contacts the alveolar ridge should be made of ceramic. In order to ensure adequate stability between the bridge pontic and the bridge abutments, a palatal and/or lingual scallop is recommended. Furthermore, to ensure even cooling of the bridge pontic that absorbs the most heat, additional cooling struts are advantageous.

Bridge pontic design – ovate pontic Bridge pontic design – saddle-type pontic

6. Interface between metal and ceramic

The interface between the metal framework and the veneering ceramic must be clearly defined. If possible, incorporate a right angle finish line. The junctures between the metal framework and the veneering ceramic must not be located in the contact area nor on surfaces involved in masticatory functions. The interface in the interdental area should be designed in such a way that cleaning of these hard-to-reach areas is possible.

Manual

In order not to damage the crown wall during processing, the crown and bridge frameworks are provided with holding pins. They are directly attached to the framework with the help of wax. Dimensions of Ø 0.5–1.0 mm for the holding pins have proven to be useful. They can be used to secure the framework by means of holding clips. Furthermore, the holding pins also act as cooling struts during casting and firing.

IPS InLine – Conventionally Layered

Important

The holding pins must be placed in such a way that they do not interfere during try-in or in the articulator. They should only be removed without causing overheating once the restoration has been completed.

Please refer to the “Framework Design Guidelines for Metal-Ceramic Restorations” for additional information on framework design. They can be ordered from your Ivoclar Vivadent contact address.

Step-by-step procedure

Starting situation

Framework design

Design the framework with a reduced anatomical shape taking the planned layering into account. The wall thickness for single crowns should be at least 0.3 mm and at least 0.5 mm for abutment crowns. Make sure to provide sufficient stability of shape for the framework. Avoid sharp transitions and edges. Design the connector areas between the individual units in such a stable way that they meet the requirements of interdental hygiene and the alloy used.

Design the framework in a reduced supported shape.

32

Alloy processing / oxide firing

The cast metal framework is finished using tungsten carbide burs or ceramic-bonded grinding instruments. To make room for the ceramic shoulder (labial or circular), the marginal area of the framework is reduced up to the inner edge of the chamfer or shoulder preparation.

37

1st and 2nd Margin firing

A ceramic shoulder can be fabricated on the metal framework after the opaquer firing, if the necessary space has been provided during finishing. Before creating the ceramic shoulder, seal the stone die with IPS Margin Sealer and then, after drying, with IPS Ceramic Separating Liquid.

correct

After that, the IPS Margin material in the respective shade is generously applied in drop-shaped increments in the cervical area (i.e. the outer surface of the ceramic is given a convex design) and dried. Then, carefully remove the framework with the dried shoulder material from the die.

Tip:

When designing a ceramic shoulder (particularly for bridges), the Margin material may be applied slightly higher up in the proximal areas. This will reduce the interdental shrinkage during the subsequent Dentin and Incisal firings.

wrong

38

After firing, the shoulder may have to be slightly adjusted by grinding in order to remove any interfering areas. Subsequently, the accuracy of fit (sinter shrinkage) has to be optimized by means of a 2nd Margin firing. Use the same Margin materials as for the 1st Margin firing for that purpose. First, however, isolate the die again using IPS Ceramic Separating Liquid. Subsequently, supplement the missing areas by carefully inserting the shoulder material into the gap created during the 1st Margin firing so that the ceramic shoulder is provided with optimum accuracy of fit. Complete the shoulder, dry, and carefully remove the framework with the completed and dried shoulder material from the die and place it on the firing tray.

Isolate the model before layering the Dentin and Incisal materials. In this way, the ceramic material is prevented from drying out or sticking to the model respectively. Isolate the stone die and the adjacent areas using IPS Model Sealer. Additionally, separate the area of the pontics with IPS Ceramic Separating Liquid.

Tip:

To achieve an optimum bond between the ceramic material and the opaquer surface, apply a small amount of IPS InLine Deep Dentin or Dentin material to the cervical and interdental areas (for bridges) and slightly roughen it. In this way, the adaption of the ceramic material on the opaquer surface is enhanced.

Make sure that the restoration is slightly overcontoured so that the actual tooth shape is achieved after firing. The bridge is lifted off the model to supplement the contact points with Dentin and Incisal materials. Before firing, separate the entire interdental area down to the opaquer.

Tip:

Densify the ceramic surface (after contouring) with a large, dry brush toward the cervical margin before firing.

true-to-nature shape and surface structure, such as growth

lines and convex/concave areas.

– Areas which should exhibit a higher gloss after Glaze firing

(e.g. pontic

rests) can be smoothed out and prepolished using silicone

disks.

– If gold and/or silver dust was used to visualize the surface

texture, the restoration has to be thoroughly cleaned with

steam. Make sure to remove all gold or silver dust in order to

avoid any discolouration after firing.

Stains and Characterization firing

Before the Stains and Characterization firing, the restoration must be free of dirt and grease. Any contamination after cleaning must be prevented. The following steps must be observed: – For better wetting of the stains, IPS InLine System Glaze and Stains liquid may be slightly agitated on the surface. – If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The applica-

tion of too many stains results in an unnatural shade effect. – The cusps and fissures can be individualized using Stains. – The basic chromatic shade is supported with the corresponding Shade material (see table).

Shade adjustment with IPS InLine System Shade and Stains

These stains may be fired in a separate Stains firing. Minor shade adjustments and individual characterizations may also be fired in the Glaze firing.

Dispense the desired quantity of IPS InLine System Shade and dilute and mix with IPS InLine System Glaze and Stains Liquid to the desired consistency. Pooling should be avoided and the material must not be applied too thickly. If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The application of too many stains results in an unnatural shade effect.

Framework design criteria

The framework design is key to the success of durable metal-ceramic restorations. The more attention given to the framework design, the better the final results and the clinical success will turn out to be.

1. Functional support of the veneering ceramic

The framework reflects the shape of the tooth in a reduced form. It should be designed in such a way that it supports the cusps and incisal edges resulting in a virtually even layer thickness of the veneering ceramic 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 ceramic. Therefore, the framework must not show any angles and edges (see diagram) so that the masticatory forces do not result in tension peaks, which may cause delamination and cracks. Any sharp angles or edges should be removed in the waxup rather than by grinding the metal framework. The wall thickness of the metal framework for single crowns must not be less than 0.3 mm and for bridge abutments 0.5 mm after finishing (see diagram). For further information, please refer to the Instructions for Use of the corresponding alloy.

2. Framework design for pressed-on ceramic shoulders

With pressed-on ceramic shoulders, make sure that the framework rather than the veneer is supported by the prepared tooth. The framework is thus reduced exactly to the inner edge of the chamfer or shoulder preparation to achieve functional support of the framework on the preparation. Excellent accuracy of fit on the preparation is essential to ensure that the shoulder material may not reach the inner aspects of the framework during subsequent application.

IPS InLine PoM – Accurate Press-On Technique

3. Framework stability

The dimensions and shape of the interdental connector surfaces significantly influence the stability of the restoration during processing as well as the clinical long-term success after incorporation. Therefore, the dimensions of the interdental connector surface must be designed in accordance with the alloy used (take the 0.2% proof stress into account)! The thermal behaviour of the selected alloy during processing has to be considered when designing the framework.

Single connector width

= single stability

Double the width of the connector

= double the stability

47

Double the height of the connector with single width

= eightfold stability

4. Framework design for bridges

Thermal stress during firing and masticatory forces after cementation affect metal frameworks. These forces must be transferred the framework rather than the veneer. Particularly in the connector areas between bridge abutments and bridge pontics in bridge reconstructions, the stability must be ensured with the help of the framework design and adequate framework material thickness. The framework design and framework thickness must therefore meet all the optical and functional requirements as well as the aspects of periodontal hygiene. A full wax-up with the corresponding reduction of the ceramic provides the most predictable results.

During veneering with ceramic materials, the bridge framework is exposed to high temperatures several times. With an inappropriate framework design or insufficient framework thickness, the high temperatures during firing may result in distortion or inaccuracy of fit of the framework. A scallop-type design with e.g. interproximal reinforcements counteracts this development. Additionally, this framework design (e.g. with cooling struts) ensures more even cooling of the restoration during the cooling phase. This is particularly important if high gold alloys are used.

In order to enable optimum oral hygiene with bridge restorations, the design of the interdental spaces should be given special attention. Adequate opening of the interdental area without creating black triangles should be given special attention when designing the framework in order to ensure proper periodontal hygiene with interdental brushes and dental floss.

48

5. Design of bridge pontics

Bridge pontics are designed with esthetic and functional aspects as well as oral hygiene in mind. The area of the pontic that contacts the alveolar ridge should be made of ceramic. In order to ensure adequate stability between the bridge pontic and the bridge abutments, a palatal and/or lingual scallop is recommended. Furthermore, to ensure even cooling of the bridge pontic that absorbs the most heat, additional cooling struts are advantageous.

Bridge pontic design – ovate pontic Bridge pontic design – saddle-type pontic

IPS InLine PoM – Accurate Press-On Technique

6. Interface between metal and ceramic

The interface between the metal framework and the veneering ceramic must be clearly defined. If possible, incorporate a right angle finish line. The junctures between the metal framework and the veneering ceramic must neither be located in the contact area nor on surfaces involved in masticatory functions. The interface in the interdental area should be designed in such a way that cleaning of these hard-to-reach areas is possible.

Manual

It is important for the press-on-metal technique that retention pins are attached to the crown and bridge frameworks. These retention pins have to be attached in the area of the pontics or the scallops. They are directly attached to the framework with the help of wax. Dimensions of Ø 1.0–1.5 mm for the retention pins have proven to be useful.

Advantages of cast-on retention pins:

1. Act as cooling struts during casting and firing

2. Retention for improved fixation in the investment material during the press-on procedure with IPS InLine PoM

3. Handling aid for further processing

The retention pins have to be shaped in such a way that the bridge framework cannot distort and/or move in the investment material. At least 2 retention pins (diverging) have to be provided for bridge frameworks, one of which has to be positioned in the area of the pontic.

If straight wax wires are used, 2 diverging wires have to be applied for bridges. A profile has to be positioned in the area of the pontic.

Pontics may also given a hollow design (e.g. Inzoma) for enhanced heat distribution and/or cooling.

Important

The retention pins must be placed in such a way that they do not interfere during try-in or in the articulator. They should only be removed without causing overheating once the restoration has been completed.

Please refer to the “Framework Design Guidelines for Metal-Ceramic Restorations” for additional information on framework design. They can be ordered from your Ivoclar Vivadent contact address.

IPS InLine PoM – Accurate Press-On Technique

Framework design

Design the framework with a reduced anatomical shape taking the planned press-on procedure into account. The wall thickness for single crowns should be at least 0.3 mm and at least 0.5 mm for abutment crowns. Make sure to provide sufficient stability of shape for the framework. Avoid sharp transitions and edges. Design the connector areas between the individual units in such a stable way that they meet the requirements of interdental hygiene and the alloy used.

Design the framework in a reduced supported shape.

– Due to the optical properties, the ceramic should feature a thickness of at least 0.8 mm in connection with

the press-on-metal technique.

– Especially if frameworks are to be pressed over, it is recommended to attach retention grooves in the

palatal / lingual area.

51

Alloy processing / oxide firing

The cast metal framework is finished using tungsten carbide burs or ceramic-bonded grinding instruments. To make room for the ceramic shoulder (labial or circular), the marginal area of the framework is reduced up to the inner edge of the chamfer or shoulder preparation.

Surface finishing before blasting Carefully blast the framework with aluminium oxide Al2O3 50–100 µm

After blasting, clean the metal framework with a steam jet and allow to dry thoroughly. Conduct the oxide firing according to the instructions of the manufacturer.

After oxide firing, the framework should exhibit an evenly oxidized surface.

(observe the instructions of the alloy manufacturer).

Opaquer firing (wash firing) (paste opaquer)

Select the IPS InLine System Opaquer paste in the corresponding tooth shade. If required, homogenize the opaquer paste by stirring it before taking it from its jar. Extrude the desired amount from the syringe or jar and mix thoroughly on the mixing pad. Thin it, if required. Apply the first opaquer layer thinly and agitate it into the alloy surface. After firing and cooling, clean the opaquerized metal framework with the steam jet and dry with oil-free air.

Tip:

The consistency of the paste opaquer can be individually adjusted using the IPS InLIne System Opaquer Liquid.

2nd Opaquer firing (paste opaquer)

Apply the second opaquer layer in such a way that the metal framework is entirely covered with opaquer. After firing, the IPS InLine System Opaquer should show a covering, silky-mat shiny surface. After the opaquer firing, the conditioned surfaces of the alloy framework should be entirely covered with opaquer.

Important

The firing tray with the opaquerized metal framework should only be placed in the firing chamber and removed from it once the furnace head is completely open and the beeper has sounded.

Wax-up

After the fabrication of the model with detachable segments and the preparation of the dies, the restoration is contoured. Use only organic waxes for contouring, since they fire without leaving residue. – Weigh the metal framework coated with opaquer and record the weight. The weight is used to determine the wax

weight after contouring. . – Subsequently, secure the framework on the model in the proper position and wax the margins first. – Fabricate a fully anatomical wax-up as usual. Observe a layer thickness of at least 0.8 mm. Make sure not to exceed a

thickness of 1.5 mm in order to ensure optimum shade reproduction. – Observe a wax thickness of at least 0.8 mm to avoid incomplete press results.

IPS InLine PoM – Accurate Press-On Technique

Fully anatomical wax-up on the metal framework. Observe the minimum layer thicknesses at all times.

57

Sprueing

The diameter for the sprues is 3 mm. For multi-unit bridges, each bridge unit must be provided with a sprue. Always attach the sprues in the direction of flow of the ceramic and at the thickest part of the wax-up so that smooth flowing of the viscous ceramic during pressing is enabled. Depending on the number of objects to be invested, either the 100 g, 200 g, or 300 g IPS Investment Ring System is selected. Bridges must only be pressed in the 200 g or 300 g Investment Ring System. The following sprueing guidelines have to be observed:

Investing

Investing is carried out using either IPS PressVEST (e.g. overnight) or IPS PressVEST Speed. For that purpose, the IPS Silicone Ring with the matching investment ring gauge is used. Determine the precise wax weight as follows: – Weigh the ring base (seal the opening of the ring base with wax). – Position the objects to be pressed on the ring base and attach them with wax. Weigh again. – The wax weight is calculated by deducting the weight of the ring base and the weight of the framework (including

opaquer) from the total weight.

Please refer to the Instructions for Use of the corresponding investment material for the detailed processing parameters. The following procedure is recommended: – Do not use a debubblizer on the wax objects. Remove separator thoroughly with oil-free compressed air. – Mix the investment material. The investment material contains quartz powder. Therefore, avoid the inhalation of dust. – Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax margins are not dam-

aged.

– Carefully place the IPS Silicone Ring on the ring base without damaging the wax objects. The silicone ring must sit flush

on the investment ring base.

– Subsequently, carefully fill the investment ring with investment material up to the marking and position the ring gauge

with a hinged movement.

– Allow the investment ring to set without manipulating it. – Do not use IPS PressVEST for investment over the weekend to prevent crystallization.

Preheating

After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the investment ring is prepared for preheating as follows: – Remove the ring gauge and ring base with a turning movement. – Carefully push the investment ring out of the IPS Silicone Ring. – Remove rough spots on the bottom surface of the investment ring with a plaster knife. Check the 90° angle. Investment

material residue must not enter the sprues. Blow into the sprues if necessary.

– If several investment rings are preheated together, mark them with the respective ingot shade. – When placing several investment rings in the preheating furnace using the Speed method, make sure that the furnace

temperature does not drop too much.

In order to ensure smooth working procedures in the laboratory on a daily basis, impeccable functioning of the infrastructure, particularly the preheating furnaces, is essential. This includes their maintenance, cleaning with a vacuum cleaner in a cool state as well as regular checks of the temperature controls and heating elements, etc. by the manufacturer.

Selection of ingots

Select the proper ingot. Only seven shades are sufficient to reproduce all the Chromascop, A-D and Bleach shades. Therefore, it is possible to press fully anatomical restorations for different patient cases in one press cycle. The final tooth shade is achieved by individual characterization using the IPS InLine System Shade/Stains and Glaze materials. Given the two ingot sizes, the objects may be optimally fabricated with the corresponding number of IPS InLine PoM ingots depending on the wax weight.

Divesting

Once the investment ring has cooled to room temperature (approx. 60 min), divest as follows: – Mark the length of the Alox plunger on the cooled investment ring. – Separate the investment ring using a separating disk. This predetermined breaking

point enables reliable separation of the investment material and the ceramic material.

– Always use polishing beads to divest the pressed objects (rough and fine divestment).

Do not use Al2O3 .

– Rough divestment is carried out with polishing beads at 4 bar (60 psi) pressure. – Fine divestment is carried out with polishing beads at 1–1.5 bar (15–22 psi) pressure. – Observe the blasting direction and distance to prevent damage to the object margins

during divestment. Cover the marginal areas thoroughly with the glove.

Separating / finishing

After separation of the sprues and smoothing of the attachment points, the pressed object is fitted to the master model. For that purpose, the usual rotary instruments (as those used for IPS Empress) are used (without pressure and overheating). After that, carefully sandblast the restoration. Finally, clean the restoration under running water or with steam. Dry thoroughly with oil-free air.

Bridge with sprues

Special attention is required for separating the palatal metal retention pin. Make sure to separate and polish the retention pin carefully after glazing without creating too much heat.

Adjustments with IPS InLine PoM Touch-Up

For minor shape adjustments, such as incompletely pressed margins or occlusal surfaces, the 7 Touch-Up materials are available in the respective ingot shade. The Touch-Up materials must only be used for metalsupported IPS InLine PoM restorations.

Processing – The restoration must be free of dirt and grease prior to adjustment. For that

purpose, clean the restoration thoroughly with a steam jet.

– Apply the IPS InLine PoM Touch-Up material mixed with IPS InLine System Build-Up

Liquid on the missing, cleaned areas using a brush and slightly blot with an absorbent

cloth.

– Place the restoration on the firing tray and fire it. – Next, finish the restoration or apply second Touch-Up adjustments and fire with the

same parameters.

Finishing and preparing for the Stains and Glaze firing

Before the Stains and Glaze firing, the restoration has to be prepared as follows: – Finish the restoration using diamond grinders and give it a

true-to-nature shape and surface structure, such as growth lines and convex/concave areas.

– Areas which should exhibit a higher gloss after Glaze firing

(e.g. pontic rests) can be smoothed out and prepolished using silicone disks.

– If gold and/or silver dust was used to visualize the surface

texture, the restoration has to be thoroughly cleaned with steam. Make sure to remove all gold or silver dust in order to avoid any discolouration after firing.

Stains and Characterization firing

Before the Stains and Characterization firing, the restoration must be free of dirt and grease. Any contamination after cleaning must be prevented. The following steps must be observed: – For better wetting of the stains, IPS InLine System Glaze and Stains liquid may be slightly agitated on the surface. – If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The

application of too many stains results in an unnatural shade effect. – The cusps and fissures can be individualized using Stains. – The basic chromatic shade is supported with the corresponding Shade material (see table).

Shade adjustment with IPS InLine System Shade and Stains

These stains may be fired in a separate Stains firing. Minor shade adjustments and individual characterizations may also be fired in the Glaze firing.

Dispense the desired quantity of IPS InLine System Shade and dilute and mix with IPS InLine System Glaze and Stains Liquid to the desired consistency. Pooling should be avoided and the material must not be applied too thickly. If a more intensive shade effect is desired, it is achieved by several staining procedures and repeated firing. The application of too many stains results in an unnatural shade effect.

– Veneers

The following chapter shows the step-by-step layering of veneers on refractory dies. Important: After each working step, the master model has to be immersed in water for about 5–10 minutes, depending on the size.

Tip:

For the veneer fabrication, smaller working steps and several intermediate firing cycles are recommended.

Model fabrication

Fabricate a duplicate model using a commercially available refractory die material, e.g. BegoForm® from Bego, Cosmotech VEST from GC or G-CERATM VEST from GC (observe the instructions of the manufacturer). Important: Correct processing and properly degassed dies are an important prerequisite for accurately fitting veneers.

Wash firing

After degassing the refractory dies, apply IPS InLine Add-On mixed with the IPS InLine System Glaze and Stains Liquid in a thin layer and fire.

General Information

Cementation

As usual, your dentist may use a conventional cementation protocol for metal-supported IPS InLine restorations or use adhesive cementation for metal-supported restorations with a ceramic shoulder as well as IPS InLine veneers. Glass ionomer cements, such as Vivaglass CEM, or self-adhesive composite cements are suitable for conventional cementation. For an adhesive cementation protocol, we recommend the Multilink Automix universal composite.
