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.

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. 
Screw the Ti base onto the model analog with the corresponding screw. – Insert a pin with the same diameter as the screw channel to "seal" and "extend"
10
the screw channel.
Isolate the Ti base and the pin with a thin application of separator.
Apply the modelling resin to the Ti base in increments.
Application procedure – Fabrication Hybrid Abutment and Hybrid Abutment Crown

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.
Application procedure – Fabrication Hybrid Abutment and Hybrid Abutment Crown
Design the emergence profile by flooding the area between the gingiva mask and the resin coping with wax. If necessary, re-insert the pin prior to modelling.
Design the abutment crown to full contour according to functional and esthetic
criteria. Check the object in relation to the opposing dentition.

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.

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.

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.

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.
