I came across this tip years ago and it has made all the difference to treating patients with invisible braces. Basically when you insert an aligner it seats about 90% of the way. Which means that it is not pushing the teeth exactly as the computer predicted, so the resulting movement per aligner is poorer than anticipated. Subsequent aligners progressively fit less and less with the typical end result being less than predicted at clincheck. The solution to this is to use Aligner Chewies made of soft rubber to seat the aligner more fully, EVERY time the aligner is put in the mouth. The resulting fully seated aligner pushes the teeth as the computer predicted aligner after aligner, meaning that better results are achieved in less time, with fewer refinements at the end of treatment.
