Retention and relapse are key concerns in orthodontics, affecting the stability of treatment outcomes. Retainers, both fixed and removable, are used to maintain teeth in their corrected positions. Despite advancements, relapse remains common due to factors like periodontal ligament elasticity and patient compliance. New strategies focus on improving retainer efficacy, enhancing patient adherence, and using adjunctive therapies. Future research aims to develop personalized retention protocols and innovative technologies to prevent relapse, ensuring long-term success in orthodontic treatments.
