Seating the hybrid abutment and dedicated crown
Note:
Temporary insertion of the IPS e.max CAD crown on the IPS e.max CAD hybrid abutment is contraindicated!
For the permanent seating of the hybrid abutment and the crown, please observe the following working steps. Please also
observe the Instructions for Use of the selected luting material.
SpeedCEM ® is recommended for the seating of IPS e.max CAD crowns on
IPS e.max hybrid abutments.
– Do not use phenolic mouth washes, as such products negatively influence the bond between the ceramic and the
composite.
– Insert the hybrid abutment intraorally into the implant.
– Manually screw in the matching implant screw.
– Tighten the implant screw with a torque wrench (observe the instructions of the manufacturer).
– Insert a cotton or foam pellet into the screw channel.
– Seal the screw channel with a temporary composite (e.g. Telio
® CS Inlay). This serves to ensure access to the screw at a
later stage.
– Check the bonding area for contamination/moisture and clean or dry with an air syringe, if necessary.
– Apply the luting material, e.g. SpeedCEM, into the conditioned crown.
– Place the crown onto the hybrid abutment and secure in place in the final position.
– Conduct the pre-polymerization using the four-quarter technique.
– Remove excess luting material.
– Cover the cementation joint with glycerine gel (e.g. Liquid Strip).
– Polymerize with an LED curing light (e.g. Bluephase
® ).
– Rinse off the glycerine gel with water.
– Check the occlusion and articulation and make adjustments, if necessary. If adjustments are made to the restoration by
grinding, these areas must subsequently be polished to a high gloss, e.g. using OptraFine.
– Polish restoration margins and the cementation joint with silicone polishers (e.g. Astropol ® , OptraFine).
– Apply Cervitec Plus in the area of the gingival margin.
The hybrid abutment is inserted into the implant intraorally. The matching implant screw is screwed in manually.
