CHOICE 2 Instructions |
 |
|
GENERAL INFORMATION |
CHOICE 2 L/C (Light-Cured) is a color-stable ( E<1.2 ),
high compressive strength, light-cured, luting cement
that is exclusively formulated for cementation of porcelain
and indirect composite veneers.
CHOICE 2 is intended for use with universal adhesives
such as ALL-BOND 2®*, ALL-BOND 3™*, ONE-STEP®* or ONE-STEP PLUS.
|
| Unlike ONE-STEP
and ONE-STEP PLUS, not all one-bottle adhesives
are compatible with dual-cured and self-cured resins.
Refer to manufacturer's instructions for more information. |
|
CHOICE 2 WATER-SOLUBLE TRY-IN PASTES are
available separately and may be used to visualize and
pre-determine the aesthetics of the final cementation.

INSTRUCTIONS FOR USE |
BONDING PORCELAIN
VENEERS:
TRY-IN and VENEER PREPARATION:
1. Make sure the porcelain veneer has been properly
etched, or etch veneer according to manufacturer's instructions
with hydrofluoric acid (such as 9.5% PORCELAIN ETCHANT*).
2. Brush on 1-2 coats of silane (when using BIS-SILANE™*
2-Part Porcelain Primer, mix parts A and B in a 1:1
ratio) inside the veneers. Wait for 30 seconds and air
dry.
(NOTE: Surface of the primed porcelain will look
the same before and after silanization.)
3. Clean the tooth preparation with a slurry of pumice,
rinse and dry.
4. Try-in the silane-coated veneers on the teeth for
proper fit. Apply the desired shade of Try-In Paste
to the veneers and gently seat on teeth. (The Try-In
Paste will not set and will match the corresponding
luting cement.) When the desired shade is determined,
remove the veneers and rinse the tooth with water. The
veneer should be rinsed thoroughly with water (or ideally,
ultrasonically cleaned in distilled water or ethanol/isopropyl
alcohol for 2-3 minutes) and dried.
TOOTH PREPARATION:
1. Clean the prepared teeth with a slurry of pumice.
Rinse and dry.
2. Isolate the prepared teeth (ideally two at a time)
with shim stock or mylar strips.
3. Etch enamel and dentin with UNI-ETCH®*
(32% phosphoric acid) w/BAC for 15 seconds. Rinse thoroughly and remove excess water
but do not desiccate; preparation should appear
visibly moist.
4. Apply Bonding Agent:
ALL-BOND 3 USERS: Mix Parts A and B in a 1:1 ratio and apply 1-2 consecutive coats to the preparation. Gently but thoroughly air dry to evaporate solvent. Surface should appear shiny. Light cure for 10 seconds at 500mW/cm2.
ALL-BOND 2 USERS: Mix PRIMERS A and B
(1:1) and apply 2-3 consecutive coats to the preparation.
(Additional coats may be required if a lot of dentin
is exposed.) Gently but thoroughly air dry to evaporate
solvent. Surface should appear shiny. Light cure for
3-5 seconds at 500mW/cm2. Apply a very thin layer of D/E RESIN* over
the primed teeth and air thin. Do NOT light cure the
D/E RESIN.
ONE-STEP USERS: Apply 1-2 consecutive
coats of ONE-STEP or ONE-STEP PLUS to the preparation.
Gently but thoroughly air dry to evaporate the solvent.
Light cure for 10 seconds at 500mW/cm2.
5. Remove the shim stock or mylar strips.
CEMENTATION:
1. Apply a very thin layer of HEMA-free resin such as
PORCELAIN BONDING RESIN* to the internal surface of
the veneer and DO NOT LIGHT CURE.
2. Apply a generous amount of the selected shade of CHOICE 2 Veneer Cement to the internal surface
of the veneer.
3. Working in pairs, carefully place one veneer at a
time and gently guide both veneers into place with passive
pressure.
4. Light cure each for 3-5 seconds at 500mW/cm2 to tack the veneers
into place.
5. Remove the excess cement.
6. Light cure each veneer for 40 seconds at 500mW/cm2 from lingual
and 40 seconds at 500mW/cm2 from the facial.
BONDING COMPOSITE VENEERS:
TRY-IN and VENEER PREPARATION:
1. Clean the tooth preparation with a slurry of pumice,
rinse and dry.
2. Try-in the composite veneers on the teeth for proper
fit. Apply the desired shade of Try-In Paste to the
veneers and gently seat on teeth. (The Try-In Paste
will not set and will match the corresponding luting
cement.) When the desired shade is determined, remove
the veneers and rinse the tooth with water. The veneer
should be rinsed thoroughly with water (or ideally,
ultrasonically cleaned in distilled water for 2-3 minutes)
and dried.
3. Lightly sandblast the internal surface of the veneer
for 1-2 seconds. Rinse and dry.
TOOTH PREPARATION:
1. Clean the prepared teeth with a slurry of pumice.
Rinse and dry.
2. Isolate the prepared teeth (ideally two at a time)
with shim stock or mylar strips.
3. Etch enamel and dentin with UNI-ETCH (32% phosphoric
acid) w/BAC for 15 seconds. Rinse thoroughly and remove
excess water but do not desiccate; preparation
should appear visibly moist.
4. Apply Bonding Agent:
ALL-BOND 3 USERS: Mix Parts A and B in a 1:1 ratio and apply 1-2 consecutive coats to the preparation. Gently but thoroughly air dry to evaporate solvent. Surface should appear shiny. Light cure for 10 seconds at 500mW/cm2.
ALL-BOND 2 USERS: Mix PRIMERS A and B
(1:1) and apply 2-3 consecutive coats to the preparation.
(Additional coats may be required if a lot of dentin
is exposed.) Gently but thoroughly air dry to evaporate
solvent. Surface should appear shiny. Light cure for
3-5 seconds at 500mW/cm2. Apply a very thin layer of D/E RESIN over
the primed teeth and air thin. Do NOT light cure the
D/E RESIN.
ONE-STEP USERS: Apply 1-2 consecutive
coats of ONE-STEP or ONE-STEP PLUS to the preparation.
Gently but thoroughly air dry to evaporate the solvent.
Light cure for 10 seconds at 500mW/cm2.
5. Remove the shim stock or mylar strips.
CEMENTATION:
1. Prime the internal surface of the veneer with ALL-BOND
2, ALL-BOND 3 or ONE-STEP:
ALL-BOND 3 USERS: Mix Parts A and B in a 1:1 ratio and apply 1-2 consecutive coats on the internal surface of the veneer. Gently but thoroughly air dry with a gentle flow of air and DO NOT light cure.
ALL-BOND 2 USERS: Mix PRIMERS A and B
(1:1) and apply 2-3 consecutive coats on the internal
surface of the veneer. Remove the excess with a gentle
flow of air. Apply a very thin layer of HEMA-free resin
such as PORCELAIN BONDING RESIN over the primed veneer
and air thin. Do NOT light cure the PORCELAIN BONDING
RESIN.
ONE-STEP USERS: Apply 1-2 consecutive
coats of ONE-STEP or ONE-STEP PLUS to the internal surface
of the veneer. Gently but thoroughly dry with a gentle
flow of air and DO NOT light cure.
2. Apply a generous amount of the selected shade of CHOICE 2 Veneer Cement to the internal surface
of the veneer.
3. Working in pairs, carefully place one veneer at a
time and gently guide both veneers into place with passive
pressure.
4. Light cure each for 3-5 seconds at 500mW/cm2 to tack the veneers
into place.
5. Remove the excess cement.
6. Light cure each veneer for 40 seconds at 500mW/cm2 from lingual
and 40 seconds at 500mW/cm2 from the facial.
