A post-orthodontic appliance crafted to maintain teeth alignment following brace removal typically presents in a few distinct forms. One common type is a clear, thin plastic tray, custom-molded to fit snugly over the teeth. Another variation incorporates a wire that runs across the front teeth, affixed to acrylic material that rests against the roof of the mouth or behind the lower teeth. A less frequently used design involves a fixed wire bonded to the back of the teeth, invisible when smiling.
These appliances are crucial in preventing teeth from shifting back to their original positions after orthodontic treatment. The benefits extend beyond aesthetics; proper alignment contributes to improved bite function and oral hygiene. Historically, variations of these appliances have been used for decades to ensure the long-term success of orthodontic interventions. The materials and designs have evolved to enhance comfort and effectiveness.
