Invisalign® Glossary


A clear, custom-made plastic tray designed to fit over the teeth and gradually move them into the desired position. Each aligner is typically worn for about two weeks.


Small, tooth-colored shapes bonded to the teeth. These attachments provide the aligners with the necessary grip to move the teeth more effectively.

IPR (Interproximal Reduction)

A process where a small amount of enamel is removed from between the teeth to create space for tooth movement. This is often done to alleviate crowding or improve bite alignment.


A 3D treatment planning software used by Invisalign providers to map out the entire treatment process, showing the anticipated movement of teeth and the final results before treatment begins.


A device worn after the completion of Invisalign treatment to maintain the new position of the teeth and prevent them from shifting back. Retainers can be clear or fixed.


Another term for an aligner, referring to the clear, custom-made plastic appliance worn over the teeth.


Additional sets of aligners provided after the initial treatment phase to fine-tune the position of the teeth for optimal results. Refinements may be needed to achieve the best possible outcome.

Bite Ramp

Small, built-in features on the aligners designed to help correct the bite by preventing certain teeth from touching and promoting the desired bite movement.
