Yes and no. All of the companies that make clear plastic aligners base their treatment on the same principles as Align Technologies (the company that created Invisalign, the first clear aligner). However, there are some differences. Invisalign’s material and methodology is patented, so other companies can’t copy the exact material or the exact methods that Invisalign uses. Therefore, other companies make their aligners out of similar materials and use a similar type of tooth movement technology. In addition, some brands don’t treat the entire mouth; only the six front top and six front bottom teeth. Be sure to ask a lot of questions about the type of invisible aligner treatment you are getting, so that you are properly informed about what sort of outcome to expect.
