by Dr David PennDigitally manufactured clear aligners have introduced a fundamentally different biomechanical environment compared with fixed appliances. Traditional force–moment terminology, derived from bracket–wire systems, inadequately describes the distributed, adaptive and emergent behaviours observed in aligner therapy.This manuscript introduces two...

Ideal Seating Protocol In an ideal world, fully compliant clear aligner patients wear their devices 22 hours a day.  This protocol is thus designed for patients who wear aligners for 22 hours per day. The 2 hours where patients are...

So the quest began, to design a device that grabbed the aligner effectively, that didn’t change the aligner shape and provided a visco-elastic force that helped seat the aligners. We assembled a team of material science experts, industrial designers and...
