The technology behind Invisalign was first developed in 1997. After receiving FDA approval in 1998, Invisalign started helping orthodontists shape their patients’ smiles in 1999. Due to obvious benefits and improvements over standard braces, Invisalign expanded to Europe in the next year and had shipped over one million patient-specific aligners by 2001. In 2003, Invisalign started becoming a standard part of dental school programs and now has successfully improved the dental health of more than one million people in over fifty lands worldwide. With shipments to China beginning in 2011, Invisalign is poised to develop a tremendous database of experience and information as the product continues to be refined and improved through ongoing research and development.
