Orthodontic retention, the crucial post-treatment phase, helps maintain dental stability and prevents teeth from shifting back to their pre-treatment positions. Traditional retainers like fixed lingual wires and Hawley retainers have been the mainstay of retention protocols for decades. However, innovations in digital technology, material science, and personalized patient monitoring have opened up modern retention protocols that promise enhanced comfort, compliance, and longevity. This review examines both traditional and contemporary retention methods, detailing their benefits and limitations, and discusses potential future trends that could further improve orthodontic retention practices.
