Force decay of polyethylene terephthalate glycol aligner materials during simulation of typical clinical loading/unloading scenarios

ConclusionAlthough the initial material stiffness of PET ‑G is relatively high, the transmission of excessive forces is attenuated by the high material-related force decay already within a few hours after intraoral insertion.
