The ONE-STEP Introductory Package does not contain composite
or cement.

| 1. |
Bisco does not recommend the
use of bases or liners. The adhesive will serve this purpose. |
| 2. |
In order to facilitate penetration
of ONE-STEP adhesive into the dentin and
enamel, the tooth surface should be left visibly moist
with water (not saliva). |
| 3. |
ONE-STEP adhesive
contains a monomer, BPDM, dissolved in an acetone solvent.
Once the 2 coats have been applied to the dentin surface,
thorough air drying for 10 seconds should be done
to remove excess solvent. Inadequate air drying to remove
the solvent completely could lead to reduced bond strength
and post-operative sensitivity . |
| 4. |
Drying ONE-STEP
adhesive with an air syringe should begin lightly to avoid
displacement of adhesive from preparation and proceed
to a fairly strong stream of air, making sure all of the
excess solvent and water have been removed. |
| 5. |
Proper air drying is extremely
important with indirect procedures such as inlays or onlays.
Pay particular attention to the line angles and margins.
Do not allow the ONE-STEP adhesive
to pool in these areas. Excessive pooling could interfere
with the final fit of the restoration. |
| 6. |
A rubber dam is essential
to the success of a porcelain repair. Also, if metal is
exposed, a sandblaster is highly recommended for optimum
adhesion. |
| 7. |
Always lubricate matrix
band prior to amalgam bonding procedure. This prevents
adhesion of amalgam to band. Hard inlay wax is recommended. |
| 8. |
AQUA-PREP™ F, an aqueous solution
of HEMA and fluoride, can be used after acid etching of
the preparation to insure that a proper level of moisture
remains on the tooth. Dispense 2 drops of aqua-prep F
into a mixing well and apply to the preparation. Allow
a dwell (soak) for 20 seconds, then gently blow off
the excess while leaving the tooth structure shiny in
appearance. Proceed with the application of ONE-STEP.
AQUA-PREP F also provides immediate, although temporary,
desensitization of dentin which will enhance patient comfort
during the application of a polymerizable bonding resin.
