RULES:
-
Etch or sandblast surfaces, as indicated.
-
Leave dentin surfaces slightly moist. Moisture should be
visible on the surface, but it should not form a pool
of water.
-
For direct bonding of composites to dentin/enamel,
etch tooth and apply two coats of DenTASTIC
UNO to the wet dentin/enamel surface. It is
best to build up a thick layer of adhesive. Light
cure for 10 seconds.
- For
direct bonding of composite to metal, sandblast
metal, apply one coat of DenTASTIC
UNO to the metal surface and light cure for 10
seconds.
-
For direct bonding of composite to porcelain,
etch porcelain with porcelain
etch gel, apply silane
and dry with clean moisture-free air, then apply one
coat of DenTASTIC UNO
and light cure for 10 seconds.
-
For bonding indirect restorations, etch dentin
and enamel and apply one layer of DenTASTIC
UNO to the tooth surface, thin this layer
with a gentle stream of air and light cure for 10
seconds. Apply one coat of DenTASTIC UNO to the restorative
surface and thin this layer. Light curing the
restorative surface is not necessary. Cement restoration
with resin cement.

Helpful
Hints:
- If
not proceeding with bonding immediately after etching,
the tooth surface can be kept wet by placing wet cotton
on the exposed dentin.
- For
direct composite restorations, when removing
the solvent with a gentle stream of air, do NOT
thin the adhesive layer. A thick layer of adhesive
gives best results. Do not push the adhesive out
to the sides, which will thin it out; instead, push
the adhesive back toward the center.
- When
bonding indirect restorations, thin the
adhesive layer so that it will not interfere with
the seating of the restoration. Light cure UNO on
the tooth surface for 10 seconds. Light curing UNO
on the restorative surface is not necessary. Cement
restoration with resin cement.
- Remember:
Direct restoration: thick adhesive layer. Indirect
restoration: thin adhesive layer.
