Ivoclar Vivadent SpeedCEM - Manual (Page 3)

1.3 Restorations made of lithium disilicate glass ceramic (e.g. IPS e.max ®
Press/CAD)
– Etch with 5% hydrofluoric acid (e.g.IPS ® Ceramic Etching Gel) for
20 seconds or according to the instructions of the manufacturer.
– Thoroughly rinse the restoration with water spray and dry with water-/
oil-free air.
– Apply Monobond ® Plus to the pre-treated surfaces with a brush or
microbrush and allow to react for 60 seconds. Subsequently, disperse
Monobond Plus with a strong stream of air.
Note
–
IMPORTANT! Contamination with saliva and blood must be avoided
during and after the pre-treatment of the restoration (try-in).
– Clean contaminated restoration surfaces as follows, regardless of any
previous conditioning:
– After the try-in, rinse the restoration thoroughly with water spray and
dry with oil-free air.
– Apply Ivoclean with a microbrush or brush to the bonding surface of
the restoration; make sure to achieve full coverage.
– Allow Ivoclean to react for 20 seconds. Then, thoroughly rinse off
with water spray and dry with oil-free air.
– If the restoration is made of lithium disilicate glass-ceramic (e.g.
IPS e.max Press/CAD), apply another coating of Monobond Plus to
the cleaned surface using a brush or microbrush, allow to react for
60 seconds and then disperse Monobond Plus with a strong stream
of air.
2. Application of SpeedCEM into the restoration
For each application, place a new mixing tip on the double syringe. Extrude
SpeedCEM from the automix syringe and apply the desired quantity directly
into the restoration. As the luting material will cure in the used mixing tip, it
may serve as a seal for the contents of the syringe until needed once again
(replace with a new tip just before the next use).
3. Placement of the restoration and removal of excess cement
a) solely self-curing
–
Seat the restoration and retain it in place exerting uniform pressure.
– Remove excess material immediately with a microbrush/brush/foam
pellet/dental floss or scaler. Make sure to remove excess material in
time, especially in areas that are difficult to reach (proximal or gingival
margins).
– To remove excess material from implant abutments, special implant
scalers/curettes should be used to avoid scratching of the implant
surface.
b) self-curing with additional light-activation to tack-cure excess
material or accelerate the curing process (quarter technique,
indicated for cases with up to 2 bridge abutments = 3- to 4-unit
bridge)
– Seat the restoration and fix/hold it in place exerting uniform pressure.
– Excess material is light-cured with the polymerization light (approx.
650 mW/cm
2 , e.g. bluephase ® LOW mode,) for 1 second per quarter
surface (mesio-oral, disto-oral, mesio-buccal, disto-buccal) at a distance
of approx. 0-10mm. Subsequently, it can be easily removed with a
scaler.
– Special implant scalers/curettes should be used to remove excess
material from implant abutments to avoid scratching of the implant
surface.
– Make sure to remove excess material in time, especially in areas that
are difficult to reach (proximal or gingival margins). After complete
curing, the removal of excess can be difficult in these areas.
– Subsequently, light-cure all cement joints again for 20 seconds (approx.
1,200 mW/cm
2 , e.g. bluephase HIGH mode).
Note
As with all composites, SpeedCEM is subject to oxygen inhibition. This
means that the surface layer does not polymerize during curing, as it comes
in contact with atmospheric oxygen. In order to avoid this, we recommend
covering the restoration margins with glycerine gel/air block (e.g. Liquid
Strip) immediately after the removal of excess. After complete polymeriza-
tion, the glycerine gel/air block is rinsed off with water.
4. Finishing of the completed restoration
– Finish proximal areas with finishing and polishing strips.
–
Check occlusion and function and adjust if necessary.
– Polish restoration margins with silicone polishers (OptraPol ® , Astropol ® ,
Politip ® -F) or discs.
Special note
SpeedCEM should have room temperature when it is applied.
Cool temperatures can render the material difficult to extrude and increase
the processing and curing times.
Do not disinfect the SpeedCEM automix syringe with agents that have an
oxidative effect.
Warning
Unpolymerized SpeedCEM paste is an irritant. Avoid contact with the skin,
mucous membrane and eyes. If SpeedCEM comes into contact with the
eyes, immediately rinse with copious amounts of water and seek medical
advice. If the material comes into contact with the skin, rinse with copious
amounts of water. Commercial medical gloves do not provide protection
against the sensitizing effect of methacrylates.
Storage
– Do not use SpeedCEM after the indicated date of expiration.
– Cool storage (2–8 °C/ 36-46 °F) for SpeedCEM.
– Store SpeedCEM automix syringe with mixing tip attached after use.

Shelf life: see expiration date.
