Invisalign uses a series of invisible, removable, and comfortable aligners that no one can tell you're wearing. Invisalign uses the latest 3-D computer technology to create your customized aligners. After you and Dr. Appel determine what you would like to correct, he will develop your precise treatment instructions. He will use Invisalign's advanced computer technology to translate those instructions into a sequence of finely calibrated aligners for you to wear during treatment.
