An orthodontic positioner is a removable appliance created specifically to retain teeth in their desired positions after they have been moved into alignment during orthodontic treatment. The positioner helps maintain the achieved results by holding the teeth steady and ensuring they do not shift back to their former positions.

Orthodontic positioners are typically used at the end of active orthodontic treatment, working alongside other retainers or appliances. They are designed to fit snugly over the teeth and may also slightly influence the positioning of the teeth by providing gentle pressure, but primarily their role is to stabilize the final alignment of the teeth.

Understanding the context helps clarify the functionality of this device, distinguishing it from other orthodontic appliances that are primarily focused on active movement or developmental growth.
