BISFIL 2B is a self-cured, radiopaque composite intended for use as the base increment of posterior composite restorations in the Directed Shrinkage Technique¹. This technique suggests that in contrast to light-cured composites, BISFIL 2B begins curing adjacent to the naturally warmer surfaces of the dentin. Since all composites shrink upon polymerization, the net effect of the Directed Shrinkage Technique is to direct polymerization toward the tooth, improving adaptation to the preparation.

BISFIL 2B is a low viscosity, syringeable composite available in shades A3/A3.5 and Universal (original). It is intended for use with adhesives such as ALL-BOND 2^®*, ALL-BOND 3^®*, ONE-STEP^®* or ONE-STEP PLUS and to be overlaid with a light-cured composite such as ÆLITE™* Aesthetic Enamel or ÆLITE All-Purpose Body.

Refer to manufacturer's instructions. Not all one-bottle adhesives bond to dual-cured or self-cured composites. Unlike others, ONE-STEP and ONE-STEP PLUS bond to dual-cured and self-cured composites.

TECHNICAL INFORMATION

At Room Temperature (20°C/68°F - 25°C/77°F):

1. Isolate tooth and prepare the cavity in a conservative manner. Clean the entire surface with a slurry of pumice and water or pumice and disinfectant such as CAVITY CLEANSER™*. Rinse and dry the preparation.

2. Etch using an etchant, such as UNI-ETCH^®* w/BAC or ETCH-37™* w/BAC according to manufacturer's instructions.

3. Apply an adhesive, such as ALL-BOND 2, ALL-BOND 3, ONE-STEP or ONE-STEP PLUS according to the manufacturer's instructions.

4. Dispense desired amount of BISFIL 2B base and catalyst pastes onto a mixing pad. If using the dual-syringe delivery system, follow the enclosed DUAL-SYRINGE INSTRUCTIONS FOR USE to dispense and deliver BISFIL 2B. If using individual syringes, dispense by turning syringe handle clockwise. After the desired amount is dispensed, turn handle counterclockwise immediately to prevent excess material extruding from syringe. Mix to a uniform paste (10-15 seconds). To minimize air incorporation, do not over-mix. Utilize instruments designed for composite placement to prevent discoloration of the composite.

5. Using a Low Viscosity Unit-Dose Tip*, place BISFIL 2B only to the level of the dentinoenamel junction. Before the end of the working time, place a small increment of a light-cured composite, such as ÆLITE Aesthetic Enamel or ÆLITE All-Purpose Body, into the preparation. Pack lightly and burnish against the BISFIL 2B in order to express entrapped air. Following final set of BISFIL 2B, continue to firmly pack a light-cured composite, building incrementally until cavity preparation is filled. Light cure according to manufacturer's instructions.

6. Check the occlusion and begin finishing procedures. After finishing and polishing procedures have been completed, apply a surface sealant, such as FORTIFY™* or FORTIFY PLUS, according to manufacturer's instructions.
OR If using BisCover™* LV Liquid Polish, finish and apply BisCover LV according to manufacturer's instructions. This will improve marginal integrity and reduce wear and staining.

STORAGE: Store at room temperature (20°C/68°F - 25°C/77°F). Refer to 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.
