The transparent, flexible correction aligner is a special aligner made of medical PET (polyethylene terephthalate) / PU (polyurethane). The material contains no plasticisers, so it is free of bisphenol A (BPA). Important for allergy sufferers.
BioForcePro® - the exclusive aligner material of the HarmonieSchiene ensures constant power transmission to the teeth during the entire treatment time. The aligners are especially fine and light and thus optimise the comfort of wearing them.
