ORTHO-TWO™
Instructions |
 |
|
|
| ORTHO-TWO
is an orthodontic two-paste direct bonding system. The
micromechanical bond to enamel utilizes the acid etch
technique and Bisco's unique composite chemistry. |
| INSTRUCTIONS |
1. Thoroughly
clean the teeth to be bonded with pumice in a rubber cup
or bristle brush. Take care to avoid irritating the gingival
tissue since slight bleeding may cause contamination that
could affect the quality of the bond.
2. Rinse thoroughly with plenty of water. Isolate the
teeth and dry with the air syringe.
3. Dispense Gel Etchant into a mixing well. Dab etchant
for 20-30 seconds on the surfaces to be bonded.
4. Rinse etched teeth thoroughly to remove all traces
of acid. Re-isolate and dry teeth to be bonded. The etched
areas should appear chalky-white. If not, reapply etchant
for an additional 30 seconds.
5. Dispense equal amounts of Bonding Resin Catalyst and
Base into a mixing well and mix thoroughly for 10-15 seconds.
Apply a thin coat to the prepared enamel surfaces.
6. Dispense equal amounts of ORTHO-TWO Catalyst and Base
Paste and mix on a mixing pad for 10-15 seconds. Apply
mixed paste to the bracket back in sufficient quantity
so that the bracket is completely covered when pressed
onto the tooth surface.
7. Place bracket with moderate pressure starting from
the gingival toward the occlusal so that excess paste
will move toward the occlusal surface. This will facilitate
easier removal of excess paste. Once paste begins to gel
on the mixing pad, do not attempt to place additional
brackets. Also, do not attempt to realign a bracket once
gelling begins.
8. Arch wires may be placed 7 minutes after the last bracket
is positioned.
9. When re-bonding is necessary, remove all hardened material
from the tooth surface. Re-etch for 30 seconds and repeat
bonding procedure.
STORAGE: Store at room temperature (22°C/72°F).
See individual component labels for specific expiration
dates.
