Preparing/conditioning the hybrid abutment with dedicated 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 procedure must be observed in the preparation of the ceramic structure for cementation on the Ti base:
– Do not blast IPS e.max CAD hybrid abutment or IPS e.max CAD crown with Al

or glass polishing beads.
– Ideally, the clinical try-in is conducted before etching to prevent contamination of the bonding surface.
– Thoroughly clean the hybrid abutment and crown with water and subsequently blow dry.
– Etch the bonding surface with 5% hydrofluoric acid gel (IPS Ceramic Etching Gel) for 20 s. The etching gel must not
come into contact with the emergence profile or the outer side of the crown. Important: No intraoral application of
the IPS Ceramic Etching Gel.
– Subsequently, thoroughly rinse the bonding surface under running water and dry it with air that is free or water and oil.
– If an adhesive or self-adhesive cementation protocol is used, apply Monobond Plus to the clean bonding surface and
allow it to react for 60 s. After this reaction time, disperse any residue with air that is free of water and oil.

The bonding surfaces are etched with IPS Ceramic
Etching Gel and subsequently cleaned.
Monbond Plus is applied to the bonding surfaces,
and allowed to react for 60 s. Excess is dispersed
with air.
