Clinical try-in
Hybrid abutment with dedicated crown
Important note: Any intraoral inspection of the occlusion/articulation and any necessary grinding adjustments
may only be carried out if the components have been attached to one other with Virtual Extra Light Body Fast Set.
Virtual has a cushioning effect during the try-in procedure, in particular, if any grinding adjustments have to be
made. Therefore, it prevents chipping in the transition area between the hybrid abutment and the crown.
The following procedure should be observed during the clinical try-in:
– The prepared hybrid abutment (provisionally secured in place) and the clean corresponding crown are laid out.
– The provisional restoration is removed.
– The hybrid abutment is screwed in manually with the dedicated screw.
– The geometry of the hybrid abutment is checked (e.g. fit, gingival anaemia) in relation to the gingival margin.
– If desired, the screw channel on the hybrid abutment can be sealed with a foam pellet.
– Tip: Isolate the inner aspect of the crown, e.g. with Try-In-Paste, Liquid Strip
– The crown is placed on the hybrid abutment intraorally to check and if necessary adjust the proxi-
mal contacts. Note: No occlusal functional inspection must be performed at this stage.
– For the functional inspection, the crown has to be secured on the hybrid abutment with Virtual
Extra Light Body Fast Set. Try-in paste must not be used for this purpose, as this material is not
sufficiently resistant to compressive force.
– The Virtual cartridge is inserted in the dispenser and the protective cap is removed.
– The mixing tip is screwed on and the Oral Tip is attached to the mixing tip.
– Virtual Extra Light Body Fast Set is applied to the inner aspect of the crown.
– The crown is pressed onto the hybrid abutments using the fingers until the final position is reached. The
crown is held in the final position until the Virtual material has set.
– Excess Virtual material is removed.
– The occlusion/articulation is checked and if necessary adjustments are made with suitable grinding instru-
ments (see separate IPS e.max recommended grinding instruments for ceramics – use in the dental practice).
If adjustments have been made by grinding, the restoration has to be re-polished or glaze fired again.
– The crown is carefully removed from the hybrid abutment, and the hybrid abutment (including the base).
– The temporary restoration is placed.
The hybrid abutment is manually screwed in place with the dedicated screw.
The geometry of the hybrid abutment (e.g. fit, gingival anaemia) is checked in
relation to the gingival margin. If desired, the screw channel of the hybrid abutment can be sealed with a
foam pellet.
