Bracket Prep:

When visualizing the amount of adhesive that needs to be applied on the back of the bracket, apply about 1/3 of the amount of a grain of rice. (1 mm)

 

  1. Add LCR 1.5g orthodontic adhesive to the LightForce Orthodontic bracket base.
  2. When Applying adhesive to the bracket base, visualize your bracket pad split into thirds. See the below instructions for technique guide:
    1. Apply Adhesive to middle third of the bracket, continue to push adhesive out of the syringe dispensing towards the gingival edge of the bracket.
    2. Scrape the tip of the syringe on the gingival edge of the bracket leaving 1 mm of adhesive on the middle and gingival thirds of the pad. 
    3. Use a composite/plastic instrument dipped in primer to push the adhesive to all 4 corners of the bracket base making sure to cover every trench of the bracket (see trenches in yellow)

      Note: Having a majority of the adhesive on the middle and gingival thirds of the pad is ideal for indirect bonding. Upon tray insertion, the adhesive will naturally push towards the occlusal surface of the pad. Having more adhesive on the gingival & middle thirds of the bracket before tray insertion will have a better chance of less flash on the tooth and under the occlusal tie wings after curing.
  3. After applying the adhesive, position the indirect bond tray so you are looking straight down into the tray. Make sure the adhesive is following the curvature of the custom pad. (concave look) If you see any bubbling (convexity) of the adhesive remove any excess with your composite instrument. (See photo below for reference)

    1. Tip- Check for any possible "bald spots" of the adhesive on the pad. If the material needs to be spread more evenly on the pad, use your composite instrument to move the adhesive on the bracket
    2. Tip- If you notice the adhesive is sticking to your instrument, add a small amount of primer to your instrument.
    3. Warning- a microbrush is not recommended for use of clean up or pushing the adhesive around the pad. The microbrush has been found to have less control of the adhesive making the adhesive touch or fall onto the IDB tray and causing tray breaking/tearing. 
  4. Lastly, Put indirect bond tray back in the LightForce box and repeat for each segmented tray. Remember to close the box in-between loading brackets. The LightForce packaging acts as a light box and will protect the adhesive from ambient light.
Tip – LightForce brackets require less cement than traditional brackets. Apply sparingly to avoid excessive flash. 
Tip – Preparing the brackets in advance saves chair time. The box can be used as a light saving box to store IDB trays before bonding.
