Press Abutment Solutions

Product Information

Press ceramics have been synonymous with esthetics, accuracy of fit, shape and function for decades. The IPS e.max Press lithium disilicate (LS2) glass-ceramic additionally offers an outstanding strength of 400 MPa. The already extensive indication range from thin veneers (0.3 mm) and monolithic molar crowns to anterior and premolar bridges is now expanded to include hybrid abutment restorations.

With IPS e.max Press, you can fabricate such restorations in combination with a titanium base (Ti base). Two different approaches are available: – Hybrid abutment and separate crown – Hybrid abutment crown Both solutions show outstanding function, efficiency and esthetics. The durable bond to the Ti base is achieved by means of the self-curing Multilink Implant luting composite.

Hybrid abutment

The hybrid abutment is an individually pressed LS2 abutment which is luted to the Ti base. The shape, emergence profile and esthetic properties of this abutment can be ideally adjusted to the clinical situation.

Individual esthetics

Given the lifelike appearance of LS2 glass-ceramics, the esthetic possibilities are virtually limitless, particularly in the anterior region. Due to the individual characterization, a lifelike appearance is achieved near the root and the transition area to the crown. With the preparation margin of the crown located on the gingival level, the geometry of the hybrid abutments allows for an easy integration of the restoration. Excess cementation material is therefore easily removed.

Flexibility due to laboratory fabrication

The pressed LS2 abutment is extraorally luted to a Ti base with Multilink Implant, then screwed into place in the oral cavity and finally provided with a permanent IPS e.max crown. As the hybrid abutment is conveniently fabricated in the lab, the process is time-saving and flexible.

Hybrid abutment crown

Hybrid abutment crowns are characterized by combining abutment and monolithic crown in one piece. This is an efficient two-in-one solution made of lithium disilicate (LS2), which is directly luted to a Ti base.

Efficient fabrication due to two-in-one approach

LS2 glass-ceramics provide for strength, durability and efficiency, particularly in the posterior area. Moreover, the material offers well-known esthetic properties allowing restorations to be simply characterized with IPS e.max Ceram stains.

Luted extraorally, screwed in intraorally – for improved flexibility

The monolithically pressed hybrid abutment crown is reliably luted to the Ti base by means of Multilink Implant. Then, the restoration is screwed onto the implant – in one piece. Thus, the bothersome task of excess cement removal is a thing of the past. Subsequently, the screw access channel is sealed with a composite material (e.g. Tetric EvoCeram®). If required, the screw can be accessed at any time, which affords the dental team clincial flexibility.

New possibilities for economically efficient restorations

IPS e.max Press hybrid abutment crowns are a new, economically attractive alternative to conventional implant-supported restorations, particularly for the posterior area, where strength, durability and convenient clinical handling matter.

Material

Uses

Press ceramic

IPS e.max Press are lithium disilicate glass-ceramic (LS2) ingots for the press technology. The industrial production process creates absolutely homogeneous ingots in different translucency levels. For IPS e.max Press Abutment Solutions, ingots from the exisitng range of products are used. The ingots feature a strength of 400 MPa and are thus the pressed ceramic ingots with the highest strength. They are pressed in Ivoclar Vivadent press furnaces to produce objects with outstanding accuracy of fit. The pressed, tooth-coloured, highly esthetic restorations are completed with IPS e.max Ceram.

Shade – tooth shade, preparation shade/abutment shade

Optimum integration in the oral cavity of the patient is the prerequisite for a true-to-nature all-ceramic restoration. To achieve this, the following guidelines and notes must be observed by both the dentist and the laboratory.

With IPS e.max Press Abutment Solutions, you can imitate not only the clinical crown of a natural tooth, but also a part of the "root". By defining/determining the "root shade" you can adjust the shade of the IPS e.max Press Abutment Solution restoration accordingly. This allows you to achieve a highly esthetic implant-supported restoration which retains its lifelike appearance also in the case of gingiva recession.

Model preparation

For the fabrication of an IPS e.max Press Abutment Solutions restoration, a model with gingiva mask is fabricated.

– Select the suitable model analog according to the implant system used. – Fabricate a model with gingiva mask.

Prepared model with gingiva mask

Selecting a Ti base

The following paragraphs outline the selection criteria for a suitable Ti base. As a general rule, the instructions of the respective manufacturer regarding the use of the Ti base have to be observed.

– Only bases consisting of Ti or Ti alloys must be used. – Select a Ti base with a size that matches the clinical situation and the chosen implant system. The geometry

requirements must be observed. – The rotation lock must be designed in such a way that stress concentrations on the pressed object are avoided. – Ti bases with undercuts, e.g. retention grooves, are suitable to some extent. – Check the available space for the pressed object taking the geometry of the Ti base into account on the model (e.g.

silicone key). – Observe the instructions of the manufacturer when modifying the Ti base.

– Create an emergence profile with a right angle at

the transition to the crown (see picture). – The wall thickness WA must be at least 0.5 mm. – The height HA must not exceed twice the height of

the Ti base HTi. – The hybrid abutment should be designed in a simi-

lar way as a prepared natural tooth: – Circular epi-/supragingival shoulder with rounded

inner edges or a chamfer.

– In order for the crown to be cemented to the

hybrid abutment using a conventional/self- adhesive cementation protocol, retentive surfaces and a sufficient "preparation height" must be observed.

– The width BAK of the crown is limited to 6.0 mm

from the axial height of contour to the screw

channel of the hybrid abutment.

– The marginal shoulder width S

must be at least

A

0.6 mm.

– The wall thickness WAK must be larger than 1.5 mm

for the entire circumference.

– The opening of the screw channel must not be

located in the contact point areas or areas with a masticatory function. If this is not possible, a hybrid abutment with a separate crown should be preferred.

– The width of the hybrid abutment crown BAK is

limited to 6.0 mm from the axial height of contour to the screw channel.

– The height HAK must not exceed twice the height of

the Ti base by more than 2 mm.

Modeling

Fabrication of a resin coping

To prepare the wax-up, a resin coping is prepared if both hybrid abutments and hybrid abutment crowns are fabricated. Please observe the following procedure:

– Check the implant position and inclination with regard to the position of the screw channel. – Screw the Ti base onto the model analog with the corresponding screw. – Tip: Make sure that an additional model analog is available as this will facilitate some steps. – Clean the Ti base with a steam cleaner. – Insert a pin with the same diameter as the screw channel to "seal" and "extend" the screw channel. – Do not apply die spacer. – Isolate the Ti base and the pin with a thin application of separator. If too much separator is used, this

might result in uneven areas on the inner aspect of the pressed object.

– In order to achieve a sound fit and to facilitate the subsequent wax-up, a coping is first fabricated on

the Ti base with modelling resin. Design the coping in such a way that it can subsequently be completely covered with modelling wax. Please observe the instructions of the manufacturer regarding the

processing of modelling resin. – Remove the Ti base from the model. – Eliminate possible over-contoured areas of the resin coping at the transition area to the Ti base by

means of rubber polishers. Do not damage the Ti base. – Remove the resin coping together with the pin from the T i base. – Loosen and remove the pin by rotating the resin coping. – Screw the Ti base onto the model analog again. – Place the resin coping back on the Ti base and check the fit and dimension (e.g. silicone key). If

necessary, adjust the coping by means of rotary instruments.

Design the coping in such a way that it can subsequently be covered with modelling wax.

11

Wax-up

Please observe the following notes with regard to modelling: – Observe the stipulated layer thicknesses. – Create an accurate model of the restoration, particularly at the transition area to the Ti base. – Do not over-contour the margins, since this would require time-consuming and risky fitting procedures after pressing. – Use an organic wax for modelling to ensure that it burns out without leaving residue in the investment ring.

Procedure for hybrid abutments

– Before creating the wax object, re-insert the isolated pin into the screw channel. – Design the emergence profile by flooding the area between the gingiva mask and the resin coping with wax. – Contour the hybrid abutment to a reduced tooth shape. The hybrid abutment should be designed in such a way that the

required layer thicknesses are met in the crown that is fabricated. Check by means of the silicone key and in relation to

the opposing dentition. – Determine the crown margins in relation to the gingiva level. – Design a chamfer on which the crown is subsequently seated. – Remove the object together with the Ti base from the model and check the emergence profile. If necessary, make

adjustments. – Check the transition to the Ti base and remove excess wax. – Check the required minimum thicknesses (page 9) prior to attaching the sprue.

Procedure for hybrid abutment crowns:

– If required, re-insert the isolated pin into the screw channel before creating the wax object. – Design the emergence profile by flooding the area between the gingiva mask and the resin coping with wax. – Design the abutment crown to full contour according to functional and esthetic criteria. Check in relation to the

opposing dentition.

– Make sure to take a slightly reduced occlusal relief into consideration during the wax-up, since the application of the

Stains and Glaze results in a slight increase in vertical dimensions.

– Remove the object together with the Ti base from the model and check the emergence profile. If necessary, make

adjustments. – Check the transition to the Ti base and remove possible excess wax. – Check the required thicknesses (page 9) prior to attaching the sprues.

13

Sprueing

Please observe the following notes when attaching the sprues to the abutment or the abutment crown: – Depending on the number and size of the objects to be invested, either the 100 g or 200 g IPS Investment Ring System

is selected. Before sprueing, weigh the ring base and record the weight (seal the opening of the ring base with wax). Please note that the mixing ratio of the investment material is different for the various restoration types (e.g. inlays,

crowns, abutments). – Use a 2.5 mm wax wire for sprueing. – For abutments, the sprue is attached to an axial surface. – For abutment crowns, the sprue is attached to a cusp. – Align the wax wire as parallel as possible to the screw channel in order to prevent the investment material

from fracturing in the screw channel.

– The maximum length (object + sprue) of 16 mm must not be exceeded. – Place the object on the investment ring base in such a way that the screw channel is parallel to the outer wall of the

investment ring. As a result, the investment material can subsequently be filled evenly and in a controlled manner. The

objects could be placed in a tilted position on the investment ring base, but this may lead to difficulties during investing

(e.g. bubbles in the screw channel). – Observe a distance of at least 10 mm between the object and the silicone ring. – If only one object is invested and pressed in an EP500 furnace, a second short (blind) sprue must be placed. This ensures

that the switch-off function of the furnace works properly at the end of the pressing procedure.

ø 2.5 mm ø 2.5 mm

Attach the sprue to a circular area of the abutment model and as parallel as possible to the screw channel. Use a 2.5 mm wax wire.

Attach the sprue to an oral cusp of the abutment crown and as parallel as possible to

the screw channel. Use a 2.5 mm wax wire.

Place the object on the investment ring base in such a way that the screw channel is parallel to the outer wall of the investment ring.

Furthermore, this reduces the risk of the investment material breaking in the screw channel while the ceramic material is pressed.

As a result, the investment material can subsequently be filled evenly and in a controlled manner.

14

Investing

Investing is carried out with either IPS PressVEST or IPS PressVEST Speed. The corresponding IPS Silicone Ring with the matching ring gauge is used for investment. Determine the weight of the object before investing. – Position the wax objects on the ring base and attach them with wax and weigh. – The difference between the empty and the loaded ring base is the definitive wax weight.

Small Ingot Large Ingot (L)

Wax weight up to max. 0.75 g up to max. 2 g

Investment Ring System 100 g and 200 g only 200 g

Please refer to the Instructions for Use of the corresponding investment material regarding the detailed processing parameters. The following basic procedure is recommended: – Do not use a debubblizer on the wax objects. – Carefully place the IPS Silicone Ring on the ring base without damaging the objects. The silicone ring must sit flush on

the ring base. – The processing temperature of the investment material is 18– max. 23 °C / 64 °F – max. 73 °F. Higher or lower

processing temperatures substantially affect the setting behaviour. – Mix the investment material. Note: The investment material contains quartz powder. Therefore, avoid the inhalation of

dust. – Important: Pour the investment material slowly into the investment ring, so that the material continuously

fills the screw channel. If the material does not sufficiently fill the screw channel, use an instrument to

carefully apply additional investment material to the screw channel from the top.

– Carefully fill the investment ring with investment material up to the marking on the silicone ring and position the ring

gauge with a hinged movement. – Allow the investment ring to set without manipulating it. – To prevent crystallization of the IPS PressVEST investment material, the invested ring must be processed within 24 hours. – If IPS PressVest Speed is used, make sure that the investment ring is placed in the preheating furnace after a setting time

of at least 30 and maximum 45 minutes.

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 with a turning movement. – Carefully push the investment ring out of the IPS Silicone Ring. – Remove the ring base with a turning movement. – 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 accordingly.

Towards the rear wall, tipped with the opening facing down Do not preheat the IPS e.max Press ingot and Alox Plunger.

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.

17

Pressing

Carry out the following preparatory steps for pressing before the preheating cycle for the investment ring has been completed: – Provide a cold IPS Alox Plunger and a cold IPS e.max Press ingot in the desired shade (please refer to the material

selection table on page 52). – Dip the cold IPS Alox Plunger into the opening of the IPS Alox Plunger Separator and keep it ready for use. – Turn on the press furnace (e.g. Programat EP 5000) in time so that the self-test and preheating phase are completed. – Select the press program for IPS e.max Press and the desired investment ring size.

Remove the investment ring from the preheating furnace immediately after completion of the preheating cycle. This step may take max. 30 seconds to prevent the investment ring from cooling down too much. – Place the cold IPS e.max Press ingot into the hot investment ring. – Insert the ingots in the investment ring with the non-imprinted side facing down. The imprinted side faces up to check

the ingot shade. – Place the side of the cold IPS Alox Plunger which has been coated with Separator into the hot investment ring. – Use the investment ring tongs to place the loaded investment ring in the centre of the hot press furnace. – The selected press program is started by pressing START.

After the end of the press cycle (optical and/or acoustic signal) proceed as follows: – Remove the investment ring from the press furnace using the investment ring tongs immediately after pressing. – Place the investment ring on a cooling grid to cool in a place protected from draft. – Do not speed up cooling, e.g. by blasting with compressed air.

Divesting

After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks, which developed during the cooling phase (immediately around the Alox plunger). This is the result of the different CTEs of the various materials (Alox Plunger, investment material and press ingot) and does not compromise the press results.

Divest the investment ring as follows: – Mark the length of the Alox Plunger on the cooled investment ring. – Separate the investment ring using a separating disc. This predetermined breaking

point enables reliable separation of the Alox Plunger and the ceramic material. – Break the investment ring at the predetermined breaking point using a plaster knife. – 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 (58 psi) pressure. – Fine divestment is carried out with polishing beads at 2 bar (29 psi) pressure. – Observe the blasting direction and distance to prevent damage to the object margins

during divestment. – Same as the outer surfaces, thoroughly blast the screw channel with polishing beads

at 2 bar (29 psi) pressure. – Remove possible ceramic residue from the Alox Plunger with type 100 Al2O3.

Removing the reaction layer

After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max Press Invex Liquid. The procedure is carried out as follows: – Pour the Invex Liquid into a plastic cup. – Immerse the pressed object in the Invex Liquid and clean in an ultrasonic cleaner for at least 10 min and at most 30 min.

Make sure that the objects are completely covered with Invex Liquid. – Use the sieve insert to remove the restoration from the Invex Liquid and clean the object under running water and blow

dry. – Carefully remove the white reaction layer with type 100 Al2O3 at max. 1–2 bar (15–29 psi) pressure. – Make sure that the reaction layer is completely removed, both from the screw channel and the outer side of the object

(repeat the procedure, if necessary). – If the reaction layer is not completely removed, problems may occur in the further course of the fabrication process. – Replace the IPS e.max Invex Liquid after 20 applications or after sedimentation of the Liquid.

To remove the reaction layer, immerse the pressed objects in IPS e.max Press Invex ... ... and place in an ultrasonic cleaner for at least 10 and at most 30 minutes.

Using Al

and a pressure of at most 1–2 bar (15–29 psi) pressure, carefully remove

... and the screw channel.

Warning

– The Invex Liquid contains < 1% hydrofluoric acid. – It is harmful when inhaled, swallowed and when it comes into contact with the skin. Furthermore, it is corrosive. – Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet). – If the material comes into contact with the eyes, immediately rinse with copious amounts of water and see an ophthalmologist

immediately. – In case of accidental contact with skin, immediately wash with plenty of water. – Use suitable protective clothing, gloves and goggles when working. – In case of an accident or physical discomfort, see a physician immediately, and take the Invex label with you, if possible.

Disposal

– Neutralize the Invex Liquid before disposal! – Use the IPS Ceramic Neutralization Powder to neutralize the Invex Liquid. – For 50 ml Invex Liquid, approx. 3–4 g of IPS Ceramic Neutralization Powder are required. – Note: strong foam development during neutralization. – Carefully add the neutralization powder to the Invex Liquid in small portions until foam is no longer formed; then allow a

reaction time of 5 minutes. – If larger quantities are disposed of, check the liquid with litmus paper (must show an alkaline reaction). – After the reaction time, pour the neutralized solution into the sink, flushing it with running water.

22

Finishing

It is of critical importance to use the correct grinding instruments for finishing and adjusting high-strength glass-ceramics (please refer to the Ivoclar Vivadent Flow Chart "Recommended grinding instruments for glass-ceramics"). If unsuitable grinding instruments are used, chipping of the edges and local overheating may occur.

Observe the following procedure for finishing IPS e.max Press restorations: – Adjustment by grinding of pressed IPS e.max Press restorations should be kept to a minimum. – Overheating of the ceramic must be avoided. Low speed and light pressure is recommended. – Make sure that the minimum thicknesses are maintained even after the minor adjustments.

Fitting to the Ti base

The fit of the abutment or abutment crown is checked on the Ti base before the sprue is separated. – Before the object is fitted, the inner aspect of the object (screw channel) is checked for bubbles in the ceramic. If

required, the bubbles are removed with suitable instruments.

– Carefully position the abutment or abutment crown on the Ti base. Note: Apply only light pressure to secure the pressed

object on the Ti base in order to prevent chipping of the ceramic. Observe the position of the rotation lock.

– Possible rough spots interfering with the fit of the pressed object on the Ti base cause greyish-black markings on the

screw channel. Carefully remove such markings with suitable grinding instruments. The diameter of the grinding instrument must be smaller than that of the screw channel. As an alternative to marking the rough spots, an occlusion spray can also be used.

– Carefully remove possible rough spots until an optimum fit between the Ti base and the pressed object is achieved.

Repeat the procedure, if required.

Finishing

Once an optimum fit between the abutment or the abutment crown and the Ti base has been achieved, please proceed as follows for the finishing steps: – Separate the sprue using a separating disc. Avoid overheating. – Smooth out the attachment point of the sprue. Make sure that the minimum thicknesses are maintained. – Check the emergence profile and the fit on the model. – In the case of abutment crowns, additionally check the occlusion and articulation. Adjust by grinding, if necessary, and

create surface textures.

– To clean the abutment crown, briefly blast the outer side with Al2O3 at 1 bar (15 psi) pressure and clean with the steam

cleaner. Some blasting devices may require different pressure settings to accomplish this procedure.

Separate the sprues using a separating disc. Avoid overheating.

The following paragraphs will explain the steps of optional staining and characterizing with IPS e.max Ceram Shades and Essences. On abutments, only the emergence profile is characterized for the individual patient. This characterization may also take place at a later stage, i.e. when the crown is characterized.

Application procedure – Fabrication Hybrid Abutment and Hybrid Abutment Crown

If abutments are fabricated, only the area of the emergence profile is characterized with IPS e.max Ceram Shades and Essences.

If abutment crowns are fabricated, the entire outer surface may be individually

characterized.

The Stains and Characterization firing is conducted with IPS e.max Ceram Shades and Essences. For further information, please refer to the IPS e.max Ceram Instructions for Use. – IPS e.max Ceram Shades are ready-to-use stains in syringes. – IPS e.max Ceram Essences are intensively shaded powdered stains, which are mixed with IPS e.max Ceram

Glaze and Stain Liquid.

The following steps must be observed: – Clean the pressed object with a steam cleaner to remove any contaminations and grease

residue. Any contamination after cleaning must be prevented.

– Tip: For the characterization, place the abutment or the abutment crown on the Ti base using a little IPS e.max Ceram

Glaze and Stain Liquid. This allows you to assess the effect of the Ti base on the shade.

– For better wetting of the stains, a small quantity of IPS e.max Ceram Glaze and Stain Liquid may be slightly rubbed into

the area that needs to be characterized.

– Mix the pastes or powders with the IPS e.max Ceram Glaze and Stain Liquids (allround or longlife) until the desired

consistency is achieved. – More intensive shades are achieved by several staining procedures and repeated firing, not by applying thicker layers. – To imitate the incisal area and translucency of the abutment crown in the incisal and occlusal third, IPS e.max Ceram

Shade Incisal may be used. – The cusps and fissures can be individualized using Essences. – If abutments are fabricated, only the area of the emergence profile is characterized with IPS e.max Ceram Shades and

Essences. Do not apply materials to the bonding surface to the crown, as this might compromise the fit and the bond. – Important: Make sure that absolutely no materials are applied to the screw channel and the interface to the Ti base in

order not to compromise the fit and bond. – Conduct the Stain and Characterization firing on a honey-comb firing tray using the stipulated firing parameters. Please

observe the special firing parameters. – Remove restoration from the furnace after completion of the firing cycle (wait for the acoustic signal of the furnace). – Allow the objects to cool to room temperature in a place protected from draft. – Do not touch the hot objects with metal tongs.

Glaze firing

Glaze firing is conducted with powder or paste glaze. On abutments, only the emergence profile is glazed. Glaze firing may also take place at a later stage, i.e. when the crown is glazed. On abutment crowns, glaze is applied to the entire outer surface.

The following procedure is recommended: – Mix the glazing material (IPS e.max Ceram Glaze Paste or Powder) with the IPS e.max Ceram Glaze and Stain Liquids

allround or longlife to the desired consistency. – Apply an even layer of glazing material covering all areas that are to be glazed. – If required, the fluorescence may be increased by applying a fluorescing glazing materal (paste or powder). – Important: Make sure that absolutely no materials are applied to the screw channel and the interface to the Ti base in

order not to compromise the fit. – Make sure that no glaze material is present on the interface of abutments and abutment crowns prior to the firing cycle.

If necessary, carefully remove the glaze material. – Conduct the Glaze firing on a honey-comb firing tray using the stipulated firing parameters. Please observe the special

firing parameters. – Remove restoration from the furnace after completion of the firing cycle (wait for the acoustic signal of the furnace). – Allow the objects to cool to room temperature in a place protected from draft. – Do not touch the hot objects with metal tongs. – If adjustments are required after Glaze firing (e.g. contact points), they may be applied using IPS e.max Ceram Add-on

Important note: Any intraoral checking of the occlusion/articulation and possible adjustments by grinding may only be

performed if the objects have been attached to one another by means of Virtual Extra Light Body Fast Set. During try-in, the Virtual material acts as a buffer, particularly if grinding is necessary, and prevents chipping in the transition area between the hybrid abutment and the crown.

Please observe the following procedure for the clinical try-in: – Have the clean prepared hybrid abutment (temporarily secured) and the matching clean crown ready at hand. – Remove the temporary restoration. – Manually screw in the hybrid abutment with the matching screw. – Check the geometry of the hybrid abutment (e.g. fit, gingival anaemia) with regard to the gingival margin. – If required, seal the screw channel on the hybrid abutment with a foam pellet. – Tip: Isolate the inner aspect of the crown with glycerin gel, e.g. Try-in paste, Liquid Strip – Place the crown intraorally onto the hybrid abutment to check and adjust the proximal contacts, if necessary.

Note: No occlusal functional checks must be performed at this stage. – For the functional check, the crown has to be secured on the hybrid abutment with Virtual Extra Light Body

Fast Set. Do not use Try-in paste for this purpose, as this material is not sufficiently resistant against the

compressive forces.

Pre-treatment of the Ti base

To prepare the Ti base for cementation with the pressed object, please observe the following procedure: – Observe processing instructions of the manufacturer of the Ti base. – Clean the Ti base in an ultrasonic cleaner and blow dry or use a steam cleaner. – Screw Ti base onto a model analog. – Place the pressed object on the Ti base and mark the relative position of the components. This facilitates locating the

correct position when the parts are assembled at a later stage. – The emergence profile of the Ti base must not be blasted or modified in any way. To protect the emergence profile,

hard modelling wax is applied, as this material can be easily removed later on. – Seal the screw channel with wax. – Carefully blast the bonding area with Al2O3 (50–100 µm) at low pressure until an even mat surface has been achieved. – Clean with an instrument and steam cleaner. Make sure that any wax residue is carefully removed. – After cleaning, any contamination of the bonding surface must be prevented, since contaminations negatively influence

the bond. – Apply Monobond Plus on the cleaned bonding surface and allow to react for 60 seconds. After the reaction time, dry

the remaining residue with water- and oil-free air. – Seal the screw channel with a foam pellet or wax. Make sure that the bonding surface is not contaminated.

Cementation with Multilink® Implant

For an optimum bond between the IPS e.max Press object and the Ti base, use the self-curing luting composite Multilink® Implant with light-curing option. Read the respective Instructions for Use for more detailed information.

Please observe the following procedure for cementation: – Keep the cleaned and conditioned components that are to be luted (pressed objects, Ti base) at hand. – The subsequent cementation procedure must be carried out quickly and without interruption. The working

time of Multilink Implant is 90 (± 15) seconds at 23 °C (± 1 °C) or 73 °F (± 1.8 °F).

– As a general rule, attach a new mixing tip to the Multilink Implant syringe prior to each use. – Apply Multilink Implant directly from the mixing tip in a thin layer on the bonding surface of the Ti base and the

bonding surface of the pressed object. – Leave the mixing tip attached to the Multilink Implant syringe until the next application. As the material will cure in the

mixing tip, it will serve as a seal. – Position the pressed object above the Ti base in such a way that the position markings are aligned. – Use even and low pressure to join the parts and check the correct relative position of the components when they are in

their final position (transition Ti base/pressed object). – Subsequently, tightly press the components together for 5 seconds. – Carefully remove excess in the screw cavity, e.g. with Microbrush or brush, using a rotary movement. – Remove excess at the transition to the Ti base carefully in its ductile state, e.g. with a foam pellet, while applying slight

pressure to hold the components in place. – Apply a glycerine gel (e.g. Liquid Strip) to the cementation joint to prevent the formation of a inhibition layer. – After that, completely polymerize the luting composite for 7 minutes in a light-polymerization device. – Important: Do not move the objects until the Multilink Implant material has completely cured and hold them

in place without allowing for any motion, e.g. with diamond-coated tweezers. – After completion of the polymerization, rinse off the glycerine gel with water. – Smooth out and polish the cementation joint with rubber polishers. – If there are any cement residues in the screw channel, remove them using suitable rotary instruments. – Clean with a steam cleaner.

General Information

Frequently Asked Questions

In addition to the desired tooth shade, why should the root shade also be defined/ determined upon shade determination?

IPS e.max Press Abutment Solutions allow you to fabricate restorations with a lifelike appearance both in the visible area and the area below the gingiva (root). By defining the root shade, a highly esthetic outcome can be achieved especially receding gingiva.

Is it possible to fabricate an abutment or an abutment crown with IPS e.max Press (LS2) without using a Ti base?

No! For this indication, IPS e.max Press needs the support provided by the Ti base. In addition, the Ti base allows an optimum (industrially fabricated) fit to the implant to be achieved.

Is it possible to use any commercially available Ti base in conjunction with IPS e.max Press Abutment Solutions?

When selecting a suitable Ti base, the requirements in terms of minimum dimensions (height, shoulder width, no undercuts) must be taken into account. In addition, the Ti base must be equipped with a rotation lock which does not entail a reduction of the ceramic layer thickness.

Is it permissible to modify the selected Ti base?

The instructions of the manufacturer with regard to modifying the Ti base must be observed. Prior to permanent cementation, the bonding surface of the Ti base must be blasted with Al2O3.

Is a hybrid abutment crown indicated in the anterior region?

This indication depends on the position and inclination of the implant. If the opening of the screw channel is located on the lingual/palatinal surface, a hybrid abutment crown may be fabricated in the anterior region.

Is it possible to use an IPS e.max Press hybrid abutment as an abutment for a bridge restoration?

No. Only single-tooth restorations may be fabricated.

What do I need to take into consideration when designing a hybrid abutment or hybrid abutment crown in order to fabricate a durable restoration?

The stipulated minimum and maximum layer thicknesses for IPS e.max Press need to be observed. In addition, the ratio between the height of the Ti base and the height of the entire restoration must be observed.

What do I need to take into consideration when attaching sprues and investing the wax-up?

The screw channel of the sprued wax-up must be parallel to the outer wall of the investment ring. As a result, the investment material can be filled evenly and in a controlled manner. In addition, the risk that the flowing ceramic material could break off the investment material in the screw channel is reduced. The objects could be placed in a tilted position on the investment ring base, but this may lead to difficulties during investing (e.g. bubbles in the screw channel). If the screw channel is very long, the investment material in the screw channel can be stabilized with a pin (e.g. high-grade steel, ZrO investing. For this purpose, pour investment material into the investment ring up to the restoration margin, insert the pin into the screw channel and fill up the investment ring up to the marking without vibrating it.

When is the sprue of the pressed object separated?

We recommend that the pressed objects should be fitted to the Ti base first, as this facilitates the handling. Subsequently, the pressed objects are separated from the sprue.

50

How should the emergence profile of the hybrid abutment be finished?

Preferably, a Characterization and Glaze firing is conducted on the emergence profile prior to the cementation procedure. In this way, you may adjust the esthetic appearance of the abutment to the clinical situation ("root shade"). If no characterization is required, the emergence profile may be polished to a high gloss with polishers as well as brushes and paste.

Is it possible to use IPS e.max Ceram Glaze Spray to glaze the abutment or the abutment crown?

We do not recommend using the Glaze Spray in this indication, as the bonding surface and the screw channel may be contaminated with glaze material.

An optional clinical try-in may be performed. How are the objects prepared for this?

The Ti base and the pressed abutment or abutment crown are temporarily joined in the laboratory by means of a silicone material, e.g. Virtual Extra Light Body Fast Set. This facilitates the intraoral handling.

What material is used to permanently cement the abutment or the abutment crown made of IPS e.max Press with the Ti base?

Only Multilink Implant is to be used for the permanent cementation. Other luting materials have not been tested for this purpose.

How is the Ti base prepared for the permanent cementation with Multilink Implant?

Carefully blast the bonding area with Al

2O3

at low pressure until an even mat surface has been achieved. After cleaning, the area is conditioned with Monobond Plus.

How is the screw channel of a hybrid abutment crown sealed intraorally?

After the hybrid abutment crown has been screwed into place and the screw has been tightened with a torque wrench, the screw channel is sealed with a composite restorative material.

General Information – Frequently Asked Questions

What must be observed for the clinical try-in of a crown on a hybrid abutment?

To check the occlusion/articulation and to make possible adjustments, the crown must be temporarily secured on the hybrid abutment with a silicone material, e.g. Virtual Extra Light Body Fast Set. The silicone material acts as a buffer and prevents chipping in the marginal area of the crown. Try-in pastes or Vaseline must not be used for functional checks.

Hybrid abutment and separate crown

The material is selected on the basis of the desired tooth shade (Bleach BL or A–D). Depending on the Ti base selected and the design of the hybrid abutment or crown, characterizations with

IPS e.max Ceram Shades and Essences may be necessary to achieve the desired shade.

The desired tooth shade is achieved after the restoration has been seated and is made up of the shade of the hybrid abutment and the shade of the crown that is cemented onto it. The ingot

recommendations for the hybrid abutment have been selected in such a way that the desired tooth shade is achieved in combination with the crown. In the "cervical area", it may be necessary

to characterize the hybrid abutment according to the clinical situation.

in the firing chamber may deviate by approx. ± 10 °C/18 °F, depending on the age of the heating muffle. – If a non-Ivoclar Vivadent furnace is used, temperature corrections may be necessary. – Regional differences in the power supply or the operation of several electronic devices by means of the same circuit

may also render adjustments of the temperatures necessary.

53

Firing parameters for IPS e.max Press Abutment Solutions

– Use a honey-comb tray and the corresponding pins for firing. – Do not use ceramic pins. – The stipulated parameters are coordinated with Ivoclar Vivadent furnaces (tolerance range +/- 10 °C/18 °F). – If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary. – Remove IPS e.max Press objects from the furnace after completion of the firing cycle (wait for the acoustic signal of the

furnace). – Allow the objects to cool to room temperature in a place protected from draft. – Do not touch the hot objects with metal tongs. – Do not blast or quench the objects.

Note regarding the firing parameters for IPS e.max Press Abutment Solutions:

Given the geometry of hybrid abutments and hybrid abutment crowns, the layer thicknesses of the pressed object may vary considerably. When the objects cool after the firing cycle, the different cooling speeds in the areas with different thicknesses may result in internal tensions. In the worst case, these tensions may result in fractures in the pressed ceramic objects. By using slow cooling (long-term cooling (L)), these tensile stresses can be minimized.

Note:

Please read the notes of the manufacturer of the ceramic furnace for more details on the programming of the long-term cooling (L). If the layer thickness is less than 2 mm on the entire pressed object, long-term cooling (L) is not required.
