Directions:
Note:
If Ortho-Choice OBA has been refrigerated, return to room
temperature before use for optimal viscosity.
- Clean::
Clean the enamel surfaces to be bracketed with an
oil-free prophy paste. Rinse and dry thoroughly.
- Isolate:
Keep teeth to be bracketed free of moisture contamination
throughout the bracketing procedure. Maintain a dry
field using standard isolation procedures.
- Etch:
Apply Etch-Rite
etching gel to the tooth surface to be bracketed for
20 seconds (40 seconds for primary teeth). Rinse with
copious amounts of water and dry with clean, oil-free
and moisture-free air. DO NOT DISTURB THIS SURFACE.
This surface should appear chalky white. If not, repeat
the above etching procedure.
- Apply
Bonding Resin: Dispense a small amount of
Ortho-Choice Bonding Resin into a mixing well and
apply a very thin coat to the etched enamel surface
with a clean brush applicator. Too much Bonding Resin
can cause brackets to drift. It is not necessary to
cure the Bonding Resin.
- Apply
Bracket Adhesive: Dispense Quick-Bond bracket
adhesive from the syringe and apply ½ mm onto the
entire tooth contacting surface of the bracket base.
Note: ORTHO-CHOICE OBA is light
activated. Keep syringe tip clean and replace syringe
cap immediately after use.
- Place
Bracket: Place the bracket on the tooth with
firm pressure so that excess adhesive is expressed
from the perimeter of the bracket. Remove excess with
an explorer or plastic instrument. Position the bracket.
The high viscosity of the adhesive is designed to
prevent bracket drift after positioning.
- Light
Cure: Light cure for 30-40 seconds (10 seconds
on each bracket side). Light curing provides total
curing and immediate bond strength.
- Place
Archwires: Archwires can be inserted and
secured immediately after light curing.
- Bracket
Removal: After treatment is completed, the
brackets are removed in the usual manner.
Warning:
Ortho-Choice OBA and Etch-Rite can cause irritation to
skin and eyes. Wear protective gloves and eyewear. If
materials contact skin, wash skin with soap and water.
If materials contact eyes, rinse with copious amounts
of water. Seek medical attention.
Caution:
When debonding from porcelain restorations, special
care must be taken. Debonding can cause porcelain to
chip, fracture or delaminate.
Note:
When bonding to porcelain, first etch porcelain surfaces
with Pulpdent Porcelain Etch Gel and apply Silane following
manufacturer’s instructions for use. The Pulpdent Porcelain
Prep Kit is ideal for this application.
Storage:
Store in cool dry place. Avoid direct sunlight.
