Step by Step Tutorial for Rebonding LightForce brackets with the Old Box & jewel case with replacement parts.
- First, remove o-ties, arch wire, & broken bracket if it's still connected to the wire. Remove any excess adhesive if necessary.
- The lid portion of the box contains a set of replacement brackets. We suggest using the back up replacement bracket when rebonding.
- If the patient comes in with the broken bracket. We ask you not to use the same bracket to be rebonded. We may not be able to see if there was any potential damage to the custom pad or break away feature of the base.
- We strongly recommend NOT to micro-etch or sandblast LightForce brackets. This can remove portions of the custom base causing potential bond failures or changes to the customization of the bracket.
- We recommend keeping the initial indirect bond tray after the initial bonding for all rebonds. If your tray was damaged at the initial bonding, make sure to reorder a new tray right away.
- Each tooth in an IDB tray is labeled with the palmer notation, to keep track of the individual jigs after use.
- Since the teeth have moved from the initial bonding, you will need to cut the tray to create an individual jig to rebond the bracket. Three instruments recommended for tray segmentation are, crown and bridge scissors, straight wire/ligature cutting pliers, or an exacto-knife. The exacto-knife is recommended for smaller or more crowded teeth, with a more precise cut. It is VERY IMPORTANT to make sure the channel the bracket slides into remains intact during segmentation.
- Next, take a set of cotton pliers or jewelers tweezers and hold the gingival edge of the pad in between the mesial and distal tie wings. Hold the IDB tray in your non-dominant hand with the inside of the tray facing yourself. Note: The disto-gingival dot of the bracket will be on the upper distal tie wing when holding the bracket with the tweezers or pliers.
- The bracket tie wings will be facing away from the technician and into the channel or labial side of the tray.
- The bracket pad will face the lingual side of the tray.
- As you slide the bracket into the channel you should feel the bracket stop as it hits the occlusal part of the tray, and locks into place. Make sure the bracket is stable in the channel, check to make sure the bracket isn't falling out or moving around in the IDB jig.
- You can load the adhesive to the bracket prior to bonding and store the individual jig in the LightForce box to protect from ambient light.
- Perform your same bonding tooth prep and isolation.
- After the tooth has been prepped, insert the tray onto the tooth with slight labial and occlusal pressure. It is important to make sure the occlusal part of the tray is fully seated on the tooth to avoid bonding the bracket too far gingivally.
- Light cure bracket 5-8 seconds and remove tray
- Check for excessive flash and for any IDB tray that may have bonded for stuck under the tie wings of the bracket
- Final Light cure the bracket for 5 seconds.
IMPORTANT : Remember to REORDER replacement brackets for the brackets that were used at the rebond.
