BISFIL II is a highly filled, self-cured, radiopaque hybrid composite recommended for posterior restorations.  The high filler concentration in BISFIL II (84% by weight) results in vastly improved abrasion resistance as well as high tensile and compressive strength. These properties are essential for composites to function effectively in the posterior dentition.

BISFIL II can be packed to the occlusal cavosurface margin for a completely self-cured restoration. It may also be used as the base increment of posterior composite restorations in the Directed Shrinkage Technique¹. This technique suggests that in contrast to light-cured composites, BISFIL II 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.  In this technique, BISFIL II needs to be overlaid with a light-cured composite such as ÆLITE™* Aesthetic Enamel.

BISFIL II is a high viscosity, paste-paste composite available in a universal shade.  It is intended for use with 4th or 5th generation adhesives such as ONE-STEP^®*/ONE-STEP PLUS, ALL-BOND 2^®*, ALL-BOND 3^®* or ALL-BOND SE^®*.

Refer to manufacturer's instructions. Unlike ALL-BOND SE and ONE-STEP/ONE-STEP PLUS, not all self-etch or total-etch one-bottle adhesives bond to     dual-cured or self-cured composites.

Working Time:
Setting Time:

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

2. If using a total-etch adhesive, etch using an etchant, such as UNI-ETCH^®* w/BAC or ETCH-37™* w/BAC according to manufacturer's instructions. OR, if using a self-etch adhesive, skip Step 2 and proceed to Step 3.

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

4. Dispense desired amount of BISFIL II base and catalyst pastes onto a mixing pad.  (If using syringes, dispense by turning syringe handle clockwise. After the desired amount is dispensed, turn handle counterclockwise immediately to prevent excess material escaping 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. Place BISFIL II directly into the preparation. Start with the proximal box up to the level of the dentinoenamel junction. Continue with composite placement to the occlusal cavosurface margin.

OPTIONAL: Place BISFIL II 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, into the preparation.  Pack lightly and burnish against the BISFIL II in order to express entrapped air.  Following final set of BISFIL II, continue to firmly pack a light-cured composite, building incrementally until cavity preparation is filled and light-curing according to manufacturer's instructions.

6. Check the occlusion and finish. To minimize or eliminate polishing, apply BisCover™* LV according to manufacturer’s instructions. Surface sealants, such as FORTIFY™* or FORTIFY PLUS, may also be used according to manufacturer’s instructions. The use of any of these products will seal the margins and reduce composite wear and staining.

STORAGE: Store at room temperature (20°C/68°F - 25°C/77°F). See individual component labels for specific expiration dates.
