IPS e.max
®
lithium disilicate hybrid abutment
and crown cemented with SpeedCEM
®
The abutment is screwed-in.
SpeedCEM ® is dispensed from the automix syringe
and the desired amount is applied directly on the
restoration.
A thin layer of Monobond ® Plus is applied on the
abutment and allowed to react for 60 seconds.
Subsequently, the abutment is dried with
moisture- and oil-free air.
The permanent restoration is tried-in. The shade, fit
and occlusion of the restoration are now checked.
The restoration is seated and held in place
maintaining stable pressure.
Etching is performed with 5% hydrofluoric acid
(e.g. IPS
® Ceramic Etching Gel) for 20 seconds.
Next, the preparation is rinsed thoroughly with
water and dried with oil-free air.
The abutment is cleaned with a polishing brush
and an oil- and fluoride-free cleaning paste (e.g.
Proxyt
® ). Subsequently, it is rinsed with water spray
and dried with oil-free air.
Excess cement material is light-cured with a poly-
merization device (e.g. Bluephase
®, approx.
650 mW/cm 2 , LOW mode) for 1 second per quarter
surface at a distance of approx. 0 – 10 mm.
Monobond Plus is applied on the pretreated
surface, allowed to react for 60 seconds and
thoroughly dispersed.
