Why do Clear Aligner Therapy patients have to wear their aligners 22 hours of every day?
If a patient leaves his or her aligner off for as little as 4 hours, the osteoclastic process of breaking down bone material can stop completely. Once this osteoclastic process stops, it can take 48-72 hours to fully get going again. A patient who regularly removes his or her aligner for long periods will be restarting the osteoclastic process over and over again, and probably won’t experience good results.
