Questions
How should the emergence profile of the
hybrid abutment be finished?
Preferably, a Characterization and Glaze firing is
conducted on the emergence profile prior to the
cementation procedure. In this way, you may
adjust the esthetic appearance of the abutment to
the clinical situation ("root shade"). If no charac-
terization is required, the emergence profile may
be polished to a high gloss with polishers as well
as brushes and paste.
Is it possible to use IPS e.max Ceram Glaze
Spray to glaze the abutment or the abutment
crown?
We do not recommend using the Glaze Spray in
this indication, as the bonding surface and the
screw channel may be contaminated with glaze
material.
An optional clinical try-in may be performed.
How are the objects prepared for this?
The Ti base and the pressed abutment or abutment
crown are temporarily joined in the laboratory by
means of a silicone material, e.g. Virtual Extra
Light Body Fast Set. This facilitates the intraoral
handling.
What must be observed for the clinical try-in
of a crown on a hybrid abutment?
To check the occlusion/articulation and to make
possible adjustments, the crown must be tempo-
rarily secured on the hybrid abutment with a sili-
cone material, e.g. Virtual Extra Light Body Fast
Set. The silicone material acts as a buffer and pre-
vents chipping in the marginal area of the crown.
Try-in pastes or Vaseline must not be used for
functional checks.
What material is used to permanently cement
the abutment or the abutment crown made
of IPS e.max Press with the Ti base?
Only Multilink Implant is to be used for the per-
manent cementation. Other luting materials have
not been tested for this purpose.
How is the Ti base prepared for the perma-
nent cementation with Multilink Implant?
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 intraorally?
After the hybrid abutment crown has been
screwed into place and the screw has been
tightened with a torque wrench, the screw
channel is sealed with a composite restorative
material.
