Clinical cases – step-by-step | IPS e.max ® lithium disilicate anterior crown cemented with Multilink ® Automix
Excess cement is light-cured with a polymerization
device (650 mW/cm
2 : 3 seconds or 1,000 mW/cm 2 :
1 – 2 seconds per quarter surface) at a distance of
10 mm using the quarter technique.
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.
Proximal areas are reworked using finishing and
polishing strips. The occlusion and function are
checked. Restoration margins are polished using
polishers (Astropol
® ) or disks.
A thin layer of Fluor Protector is applied. The
varnish is evenly dispersed and dried with an air
syringe.
Excess material is now easily removed with a scaler. In order to prevent oxygen inhibition, the restora-
tion margins are covered with glycerine gel/air block
(e.g. Liquid Strip) immediately after the removal of
excess.
