It was, in fact, the first true clear aligner system. In 1993, American orthodontist, John Sheridan devised the Essix retainer which is still in use today. This is the decade where it all ‘kicked off’ as far as aligners for teeth are concerned. Known as Elastomer Devices, they were a huge breakthrough because, for the first time, tooth movements of up to 3mm could be achieved using a single Elasto appliance. While they were still a million miles from the sleek, sophisticated clear teeth aligners we know today, they were by the mid-1970’s, recognized as a form of orthodontic treatment and became more and more widespread.īy the 1980’s plastic was replaced by silicon. 1960’s to the 1980’sīy the mid-1960’s researchers started to document the success of so-called ‘one-piece plastic splints’ which by this time were now being used to make minor teeth corrections. Used in conjunction with traditional braces, it sped up the process and is considered the frontrunner of what we know today as clear aligners. Made of rubber and worn on both teeth quadrants, the ‘tooth positioner’ as it was known, was really the first non-metal, removable device for straightening teeth. In 1945 an American orthodontist by the name of Harold D Kesling invented a removable custom-designed appliance that looked and functioned similarly to a mouth guard. While it’s true that the Invisalign brand went a long way towards turning the orthodontic industry on its head, the idea behind moving teeth using removable appliances actually stretches back to the 1940’s. You’d probably be forgiven for thinking that removable clear aligner treatment for teeth started with Invisalign.
