What is the primary purpose of an orthodontic positioner?

The primary purpose of an orthodontic positioner is to retain the teeth in their desired position after orthodontic treatment is completed. After braces are removed, the positioner helps to ensure that the teeth do not shift back to their original positions, which can occur if they are not stabilized. This stabilization process is essential to allow the surrounding tissues and bone to adjust to the new alignment.

Positioners are designed to fit over both the upper and lower teeth, applying gentle pressure to maintain their alignment and ensuring that the bite relationships remain intact. Retention is a critical phase of orthodontic treatment because it ensures the long-term success of the alignment achieved through braces or other orthodontic appliances.

While enhancing aesthetic appearance and straightening teeth are important aspects of orthodontics, the specific role of the positioner focuses on maintaining the achieved results. Similarly, replacing missing teeth is not related to the function of a positioner, as that is typically addressed through prosthodontics, such as dental implants or bridges.
