The temporary restoration is removed. The prepara-
tion is cleaned with a polishing brush and an oil-
and fluoride-free cleaning paste (e.g. Proxyt
®
fluoride- free). Subsequently, it is rinsed with water
spray and dried with oil-free air.
The desired amount of SpeedCEM ® is applied
directly onto the bonding surface of the restoration.
The permanent restoration is tried-in. The shade,
fit and occlusion of the restoration are checked.
The inner surface of the restoration is cleaned by
blasting it (e.g. IPS e.max
® ZirCAD, 1 bar,
Al
2
O
3
100 μm).
The restoration is seated and held in place
maintaining stable pressure.
The preparation is cleaned again with a polishing
brush and an oil- and fluoride-free cleaning paste
(e.g. Proxyt
® fluoride-free). Subsequently, it is rinsed
with water spray and dried with oil-free air. Over-
drying must be avoided.
Excess cement material is light-cured with a poly-
merization device (approx. 650 mW/cm
2 ) for
1 second per quarter surface at a distance of
approx. 0 – 10 mm.
