Rebonding Protocol & Tray Segmentation Instructions

Step by Step Tutorial for Rebonding LightForce brackets

* note for front office staff- receiving a phone call from the patient with a broken LightForce bracket will be a good time to create and start the reorder process. This will ensure that there is a replacement bracket on the way for the replacement bracket that will be bonded at the Rebond appointment. Click Here for Reorder Instructions

*note for clinical technician- if you notice a broken bracket at an arch wire change visit, use the replacement bracket for rebond and immediately create a reorder for a new replacement bracket. Inspect the broken bracket, if the bracket seems to be intact, keep that bracket aside in the LightForce box until the replacement bracket comes in. Click Here for Reorder Instructions

* remove o-ties, arch wire, & broken bracket if it's still connected to the wire

We strongly recommend NOT to micro-etch or sandblast LightForce brackets. This can remove or distort part of the custom base and cause potential bond failures after rebonding. We suggest using the back up replacement bracket when rebonding.

  1. For Rebonding with LightForce we recommend using the replacement brackets, even if the patient comes into the office with the broken bracket. The reason for this is because we may not be able to see if there was any potential damage to the custom pad or break away feature of the base. 
  2. 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. 
  3. Each tooth in an IDB tray is labeled with the palmer notation, to keep track of the individual jigs after use. 
  4. 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. 
  5. 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. 
  6. 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. 
  7. Perform your same bonding tooth prep and isolation. 
  8.  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. 
  9. Light cure bracket 5-8 seconds and remove tray
  10. Check for excessive flash and for any IDB tray that may have bonded for stuck under the tie wings of the bracket
  11. Final Light cure the bracket for 5 seconds.

IMPORTANT :  Remember to REORDER replacement brackets  for the brackets that were used at the rebond.
