Clear aligners became available for treatment circa 1999. But the truth is, as Invisalign’s stats show, no significant amount of treatment was rendered for the first 15 years. However, there has been a MAJOR surge in Invisalign treatment during the past 5 years. Upon closer examination, this makes sense; it took time to perfect technology, to perfect the skills, and to employ the knowledge of traditional braces that translated well to clear aligners. The times have changed, and the number of patients, adults, teenagers, and children seeking orthodontic treatment has increased, as has the demand for comfort and aesthetics. As is the case with anything else, it is always important to take into account the amount of exposure and experience that a doctor has with clear aligner treatment. Patients take it for granted that a doctor is up to date with the latest technology in the industry. However, familiarity and experience are NOT the same. Choose someone who knows how clear aligners work.
