Clinical cases – step-by-step | IPS e.max ® lithium disilicate veneer cemented with Variolink ® Veneer
Heliobond is applied and dispersed to a thin layer.
Heliobond is only polymerized together with the
cementation material.
In order to prevent oxygen inhibition, the restoration
margins are covered with glycerine gel/air block
(e.g. Liquid Strip) immediately after removal of
excess.
Variolink Veneer is applied directly onto the
preparation and/or onto the inner side of the
restoration, if required. Subsequently, it is seated
and held in place maintaining stable pressure.
If a curing light with an output of at least
800 mW/cm
2 is used, each mm of the ceramic
material and segment is polymerized for at least
10 seconds. Subsequently, Liquid Strip is rinsed off.
The cementation steps are repeated for all veneers.
Proximal areas are reworked using finishing and
polishing strips. The restoration margins are
polished using polishers (Astropol
® ) or disks.
A thin layer of Fluor Protector is applied, evenly
dispersed and dried with an air syringe.
The restoration is tacked in place by light-curing
a small area for 3 – 4 seconds (e.g. Bluephase
® ,
650 mW/cm 2 , LOW mode). Excess material is
removed using a suitable instrument.
