Sterilization
We recommend sterilizing hybrid abutments or hybrid abutment crowns before seating
them in the patient's mouth.
– The sterilization time is 15 minutes at 121 °C / 250 °F.
– Only devices which comply with the standards EN 13060 and EN 285 should be
used for sterilization. The sterilization processes are validated according to
EN ISO-17664:2004.
Intraoral preparation
Please observe the following procedure to prepare for the permanent cementation of the implant-supported restoration:
– Remove the temporary restoration.
– Clean the implant site.
– Check the periimplant tissue (emergence profile).
Seating the hybrid abutment and crown
Preparing/conditioning the hybrid abutment and crown
Conditioning of the ceramic surface, i.e. the bonding surface, in preparation for cementation is critical for generating a
sound bond between the cementation material and the all-ceramic material.
The following steps must be observed:
– Do not blast the IPS e.max Press hybrid abutment or the IPS e.max Press crown with Al

or glass polishing beads prior
to seating.
– Ideally, conduct the clinical try-in before etching in order not to contaminate the bonding surface.
– Thoroughly clean the hybrid abutment and the crown with water and blow dry.
– Etch the bonding surfaces with 5% hydrofluoric acid gel (IPS Ceramic Etching Gel) for 20 seconds. Make sure that no
etching gel comes into contact with the emergence profile or the outer side of the crown. Important: Do not use the
IPS Ceramic Etching Gel intraorally.
– Thoroughly rinse off the etching gel with water and dry with oil- and water-free air.
– If an adhesive or self-adhesive cementation protocol is used, apply Monobond Plus to the bonding surfaces,
allow to react for 60 seconds and then dry with oil- and water-free air.
