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 restoration is seated and held in place
maintaining stable pressure.
Monobond ® Plus is applied on the pretreated surface,
allowed to react for 60 seconds and then thoroughly
dispersed with air.
The permanent restoration is tried-in. The shade, fit
and occlusion of the restoration are now checked.
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.
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- and moisture-
free air. Overdrying must be avoided.
Etching is performed with 5% hydrofluoric acid
(e.g. IPS
® Ceramic Etching Gel) for 20 seconds.
Subsequently, the preparation is rinsed thoroughly
with water and dried with oil-free air.
The gel-like excess material is now easily removed
with a scaler.
SpeedCEM ® is dispensed from the automix syringe
and the desired amount is applied directly on the
bonding surface of the restoration.
