In order to prevent oxygen inhibition, the restoration
margins are covered with glycerine gel/air block (e.g.
Liquid Strip) immediately after the removal of excess.
Proximal areas are reworked using finishing and
polishing strips. The occlusion and function are
checked. Restoration margins are polished using
polishers (OptraPol
® Next Generation) or disks.
A thin layer of Fluor Protector is applied. The varnish
is evenly dispersed and dried with an air syringe.
Subsequently, all cementation joints are light-cured
(approx. 1,200 mW/cm
2 ) again for 20 seconds.
If non-translucent, opaque restorative materials are
used, self-curing must be completed.
Subsequently, Liquid Strip is rinsed off.
