Why should I feel confident about Invisalign?
How many patients have been treated with Invisalign? More than 1.3 million patients worldwide have been treated with Invisalign. The number of Invisalign smiles grows daily. What are aligners made of, and what do they look like?

No. Invisalign aligners and Vivera Retainers do not contain Bisphenol-A or phthalate plasticizers.

Tests have been conducted to determine the biocompatibility of these materials, and show that they are biocompatible and pass all applicable regulatory requirements and thresholds for human wear in the mouth.
