Orthodontic Retainers: An In-Depth Review

Abstract

Orthodontic treatment is not merely about achieving proper alignment of teeth, but also about maintaining the achieved results over the long term. A significant challenge faced by orthodontists is the tendency of teeth to return to their original positions—a phenomenon known as relapse. Orthodontic retainers are specialized appliances designed to counteract this tendency and preserve the stability of corrected dentition. They serve as the crucial final phase of orthodontic therapy, often determining the long-term success of treatment. This article provides a comprehensive review of orthodontic retainers, including their types, biological basis, materials, clinical protocols, complications, and future innovations.
