CHOICE is a light-cured/dual-cured aesthetic resin cement that is ideal for cementation of porcelain or composite indirect restorations. Each 4.5g syringe contains the LIGHT-CURED RESIN CEMENT which is ideal for veneers. The dual-cured mode is recommended for cementation of porcelain or composite inlays, onlays, crowns and bridges. CHOICE is intended for use with adhesives such as the ALL-BOND 2^®*, ALL-BOND 3™*, and ONE-STEP^®*/ONE-STEP PLUS adhesive systems. CHOICE WATER-SOLUBLE TRY-IN PASTES are available and may be used to achieve highly aesthetic results.

• Veneers
• Inlays
• Onlays
• Crowns
• Bridges

NOTE: When "Restoration(s)" appears in this section, it refers to inlays, onlays, crowns and bridges.

1. SHADE SELECTION with WATER SOLUBLE TRY-IN PASTE

• TRY-IN PASTES will not set and may be mixed together to produce virtually any desired shade.
• Each shade of TRY-IN PASTE matches the corresponding "cured" RESIN CEMENT shade.

a. Clean the tooth preparation with a slurry of pumice; rinse and dry.

b. For Composite Veneers/Restorations: Continue with step c.
For Porcelain Veneers/Restorations: 
• If the laboratory has not etched the veneer/restoration, contact lab for proper etching instructions. 
• To the etched internal surface, brush on 1-2 coats of BISCO’s PORCELAIN PRIMER* or a 2-Part silane such as BIS-SILANE™* to the internal surface and wait for 30 seconds. Dry with air syringe.
NOTE: Surface of the porcelain will look the same before and after silane application.

c. Place the selected shade of TRY-IN PASTE on the veneer/restoration and gently seat on tooth. Remove TRY-IN PASTE by rinsing with water. (Repeat if necessary.)

d. When the desired shade has been selected, remove the veneer/restoration. Clean the tooth preparation with water. Rinse the veneer/restoration with water and then ultrasonically clean in distilled water for 2-3 minutes. Dry thoroughly.

2. VENEER/RESTORATION PREPARATION

For Porcelain Veneers/Restorations:

a. ALL-BOND 2 or 3 USERS: Apply a very thin layer of a HEMA-free resin such as PORCELAIN BONDING RESIN* to the silanated internal surface.  Do NOT light cure!
ONE-STEP USERS: Apply 1 coat of ONE-STEP or ONE-STEP PLUS to the silanated internal surface. Gently but thoroughly air dry to evaporate the solvent. Do NOT light cure!

b. Continue with Steps #3 (TOOTH PREPARATION) and #4 (CEMENTATION) below.

For Composite Veneers/Restorations:

a. Sandblast the internal surface of the veneer/restoration for 1-2 seconds. Rinse and dry.

b. ALL-BOND 2 USERS: Mix PRIMERS A and B (1:1) and apply 2-3 consecutive coats on the internal surface of the veneer/restoration. 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/restoration and air thin. Do NOT light cure the PORCELAIN BONDING RESIN.
ALL-BOND 3 USERS: Mix Parts A and B (1:1) and apply 1-2 coats to the internal surface of the veneer/restoration. Gently but thoroughly air dry until there is no visible movement of the material. Light cure for 10 seconds.
ONE-STEP USERS: Apply 1 coat of ONE-STEP or ONE-STEP PLUS. Gently but thoroughly air dry to evaporate the solvent. Do NOT light cure!

c. Continue with Steps #3 (TOOTH PREPARATION) and #4 (CEMENTATION) below.

3. TOOTH PREPARATION

a. Clean tooth preparation with a slurry of pumice, rinse, and dry.

b. Etch tooth preparation with an etchant, such as UNI-ETCH^®* w/ BAC (32% phosphoric acid), for 15 seconds. Rinse with water and lightly air dry.
NOTE: Remove excess water but do not dessicate. Preparation should appear visibly moist.

c. ALL-BOND 2 USERS: Mix PRIMERS A and B (1:1) and apply 2-3 consecutive coats. Gently but thoroughly dry with air syringe to evaporate solvent. Light cure for 3-5 seconds. Apply a thin layer of PRE-BOND*, air thin, and do NOT light cure!
ALL-BOND 3 USERS: Mix Parts A and B (1:1) and apply 1-2 consecutive coats. Gently but thoroughly dry with air syringe to evaporate solvent. Light cure for 3-5 seconds.
ONE-STEP USERS: Apply 1-2 consecutive coats of ONE-STEP or ONE-STEP PLUS. Gently but thoroughly air dry to evaporate the solvent. Light cure for 10 seconds.

4. CEMENTATION

a. Apply selected shade(s) of CHOICE RESIN CEMENT to the internal surface of the prepared veneer/restoration.

b. Seat the veneer/restoration on the tooth with gentle, passive pressure.

c. (Optional) Light cure for 10 seconds to tack the restoration into place.

d. Remove excess cement.

e. Beginning with the lingual surface, light cure for 40 seconds per surface.

If dark or opaque veneers have been selected to mask staining or if cementing an inlay, onlay, crown or bridge, use CHOICE DUAL-CURED CATALYST (either PASTE or LIQUID) to ensure thorough curing of the cement. Mix one-half inch (1.27 cm) of CHOICE RESIN CEMENT and one drop of DUAL-CURED LIQUID CATALYST; OR mix equal volumes of CHOICE RESIN CEMENT and DUAL-CURED PASTE CATALYST.

STORAGE: Store at room temperature (22°C/72°F). See individual component labels for specific expiration dates.

PRECAUTIONS: Unpolymerized resins may cause skin sensitization in susceptible persons. In case of contact with the skin, wash thoroughly with soap and water. Phosphoric acid of UNI-ETCH is a severe eye irritant and tissue irritant. If accidentally instilled into the eye, flush with copious amounts of water and seek medical attention immediately. In case of contact with other tissues, rinse immediately with plenty of water for several minutes. Injury may result if UNI-ETCH is allowed to remain on the skin or mucosa for extended periods of time.
