ORTHO-ONE is an orthodontic no-mix

ORTHO-ONE is an orthodontic no-mix direct bonding system. The micromechanical bond to enamel utilizes the acid etch technique and Bisco's unique composite chemistry.


INSTRUCTIONS FOR USE

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 Liquid 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. Rinse and dry again.

5. Brush a thin coat of ORTHO-ONE No Mix Primer on to each etched and dried tooth surface to be bonded. The thin primer coat should be confined to the etched area. To avoid evaporation, do not dispense primer prematurely.
NOTE: When using no-mix bonding systems, bracket bases should closely conform to the tooth surface to be bonded. Adjust bracket base as needed.

6. Brush a thin coat of ORTHO-ONE No Mix Primer on the underside of the bracket base. Do not contaminate primed surface of bracket base. Primed surfaces should not be exposed to air for more than 10 minutes. If primed bracket base should become contaminated with saliva, etc., clean primer from bracket base with alcohol or acetone, rinse and dry bracket thoroughly. Then apply primer again.

7. Apply a thin layer of ORTHO-ONE No Mix Paste to the underside of the bracket base and immediately place bracket on tooth with a slight rotating motion. Immediately position the bracket to desired angulation and press firmly to insure paste is in a thin uniform layer. All adjustments to brackets must be made within 20 seconds (prior to gelation of paste). Remove excess adhesive from the periphery of the bracket base after the brackets are in place. Keep teeth isolated for approximately 3 minutes. Archwires may be placed 7 minutes after bracket is placed on the tooth.

8. To re-bond a lost bracket, all adhesive must be removed from the tooth, then follow steps 1-7.
