Abstract
A method for orthodontic treatment includes providing a first set of aligners to a user. The first set of aligners includes a first aligner, a second aligner, and a third aligner configured to move a tooth of a user. The first aligner, the second aligner, and the third aligner are created using a single physical dental model and are substantially the same shape. The first aligner has a first thickness, the second aligner has a second thickness, and the third aligner has a third thickness. The first thickness is different than the second thickness and the third thickness, and the second thickness is at least substantially equivalent to the third thickness.
