Abstract: Dental attachments used with a series of transparent dental aligners are secured to the teeth in their desired locations before the transparent aligners are made. The attachments are pre-made and applied to the teeth as one of the first steps in the process of realigning the teeth. A computer model of the teeth, including the attachments secured to the teeth, is then made. The movements of the teeth are designated in the computer model. The series of individual transparent aligners are then designed and made for eventual application to the teeth in sequence to realign the teeth. The attachments may be made at any time in advance of their use and may contain removable handles for fast and easy placement on the teeth.
