equently Asked Questions
Can a glaze spray be used for glazing IPS e.max CAD ceramic
structures (e.g. IPS e.max CAD Crystall./Glaze Spray)?
We do not recommend using the Glaze Spray for the indications
hybrid abutment or hybrid abutment crown, as there is a risk that
the bonding surface to the Ti base or the scew channel are conta-
mination with glaze.
What material is used to permanently cement the IPS e.max
CAD ceramic structures to the Ti base?
Only Multilink Hybrid Abutment is to be used for permanent cemen-
tation. This ensures a high-quality bond. Given the high opacity of
the luting composite, complete optical masking of the Ti base is
achieved and thus an excellent esthetic appearance ensured.
How is the Ti base prepared for the permanent cementation
with Multilink Hybrid Abutment?
Provided it has been approved by the manufacturer, carefully blast
the bonding area with Al

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
after seating?
The screw channel is extraorally conditioned (etching, silanating).
After the restoration has been intraorally screwed down on the
implant, the screw channel is sealed with a restorative composite.
