Pretreatment
1. Sand blast with aluminum
oxide ≤40 µm
2. Clean withalcohol, rinse, dry
1. Etch with HF acid
2. Rinse 15(s), dry with airfree of oil
3. Silane treatment
1. Sand blast with aluminum
oxide 40 µm
2. Clean withalcohol and dry
Optional: For increased adhesion, treat
internal surface with Rocatec
TM
or
Co-Jet
TM
followed by silane treatment.

Mixing:
•Insert activated capsule into mixing
device (triturator/amalgamator).
•Mix 10 seconds for 3M™ESPE™
RotoMix™Capsule Mixing Unit.
•Mix 15 seconds athighest speed for
other mixing devices.

Pretreatment of Restoration:
See pretreatment recommendations table
or instructions for use.
Activation:
•Insert capsule into Activator.
•Press down handle completely and
hold for 2-4 seconds.
Preparation:
•Remove provisional restoration and
all temporary cement residue.
•Trial fit the restoration and clean
thoroughly.

Indicated for Final Cementation of:
•Metal and porcelain-fused-to-metal crowns, bridges, inlays
and onlays.
•All-ceramic/composite crowns, bridges, inlays and onlays.
•Strengthened core ceramic crowns and bridges.
•Pre-fabricated and cast posts and pins.
•CAD/CAM milled composites, ceramic.

Pretreatment of Tooth:
•Use a pumice slurry, rinse, lightly dry.
Do Not Overdry.
Note: Please Follow the Instructions for Use.
H2O2should not be used. The use of substances
such as desensitizers, disinfectants, astringents,
and dentin sealants, etc., after final cleaning
with pumice paste and water is not recommended.
Their residues may have a detrimental effect
on the bonding strength and setting reaction
of the cement.

CEMENTATION TECHNIQUE
Dispensing:
•Remove capsule from mixing device
and insert into Applier.
•Open nozzle and dispense cement
directly onto bonding surface of
restoration or directly onto tooth surface
for inlays and onlays. For posts and
pins, do not use a Lentulo-Spiral.
•Working time from start of mix:
Aplicap 2:00 min.
Maxicap 2:30 min.

6
Placement:
•Seat restoration and hold in place with
light pressure.
•Excess cement is best removed in the
cement’s gel state with scaler or explorer.
Tack cure excess with light for 2 seconds
or allow to self-cure for 2–3 minutes
from start of mix.
•It is important to check occlusion after
the cement is set so that the cement is
not disrupted.

8
Final Cure:
•For translucent ceramic restorations,
light-cureeach surface for 20 seconds.
•For all others, allow cement to self-cure
Aplicap 5:00 min. from start of mix.
Maxicap 6:00 min. from start of mix.
Finish and Polish:
•Insure all excess cement is removed.
•Adjust occlusion.
•Finish exposed surfaces using appropriate
instrument and polishing paste.
•Finish proximal surfaces using
3M™ESPE™Sof-Lex™Discs and Strips.
