Recommended Procedure

  1. Carefully remove the OrthoFX aligners and any additional accessories from the OrthoFX package and examine them for defects. Do not use defective appliances.
  2. Rinse the OrthoFX aligners thoroughly with cool water.
  3. Place the OrthoFX stage 1 aligners on your teeth and push down.
  4. Wear these stage 1 aligners for 22 hours a day for one week.
  5. OrthoFX aligners will fit tightly and will apply pressure to your teeth. This pressure will lessen over time as you wear your aligners.

    Note: You may notice a slight lisp when you initially start wearing your aligners. This typically goes away after a few days. You may experience dry mouth during aligner treatment; if so, please drink water.

  6. Wear each stage of aligners for one week before advancing to the next stage of aligners, or as prescribed by your doctor.
  7. Your aligner packages are sequentially numbered for easy identification. Once you have worn the aligner for one week, move to your next aligner.
  8. Once you have moved onto the next aligner in your treatment, keep your previously worn aligner in the package it came in, just in case you lose or break your current one. Before storing the aligner, rinse thoroughly with cool water.
  9. After treatment is complete, dispose of aligners in accordance with local government policy.

Period of Use/Storage

  1. The aligner should be worn 22 hours per day.
  2. Do not wear aligner after the expiration date printed on the bag it came in.
  3. Store your aligners in the provided OrthoFX aligner case when not wearing them.
