Clinical try-in
Hybrid abutment
Important note: Any intraoral checking of the occlusion/articulation and possible adjustments by grinding may only be
performed if the objects have been attached to one another by means of Virtual Extra Light Body Fast Set. During try-in,
the Virtual material acts as a buffer, particularly if grinding is necessary, and prevents chipping in the transition area
between the hybrid abutment and the crown.
Please observe the following procedure for the clinical try-in:
– Have the clean prepared hybrid abutment (temporarily secured) and the matching clean crown ready at hand.
– Remove the temporary restoration.
– Manually screw in the hybrid abutment with the matching screw.
– Check the geometry of the hybrid abutment (e.g. fit, gingival anaemia) with regard to the gingival margin.
– If required, seal the screw channel on the hybrid abutment with a foam pellet.
– Tip: Isolate the inner aspect of the crown with glycerin gel, e.g. Try-in paste, Liquid Strip
– Place the crown intraorally onto the hybrid abutment to check and adjust the proximal contacts, if necessary.
Note: No occlusal functional checks must be performed at this stage.
– For the functional check, the crown has to be secured on the hybrid abutment with Virtual Extra Light Body
Fast Set. Do not use Try-in paste for this purpose, as this material is not sufficiently resistant against the
compressive forces.
– Insert the Virtual cartridge into the dispenser and remove the protective cap.
– Screw on the mixing tip and attach the Oral Tip to the mixing tip.
– Apply Virtual Extra Light Body Fast Set to the inner aspect of the crown.
– Use your finger to press the crown to the hybrid abutment until the final position has been achieved. Hold the crown in
the final position until the Virtual material has set.
– Remove excess Virtual material.
– Check the occlusion/articulation and make required adjustments with suitable grinding instruments (see separate
IPS e.max Recommended grinding instruments for ceramics – use in the dental practice). If adjustments have been made
by grinding, conduct another polishing cycle or glaze firing.
– Carefully remove the crown from the hybrid abutment and the hybrid abutment (including Ti base).
– Insert the temporary restoration.
Manually screw in the hybrid abutment with the matching screw. Check the geometry
of the hybrid abutment (e.g. fit, gingival anaemia) with regard to the gingival margin.
If required, seal the screw channel of the hybrid abutment with a foam pellet.
