title: Rationale for retention following orthodontic treatment.
abstract: Maintaining the treatment result following orthodontic treatment is one of the most difficult aspects of the entire treatment process. Normal maturational changes, together with post-treatment tooth alterations, conspire against long-term stability. This article discusses the need for retention and provides an overview of retainers which enjoy widespread use.
  
  
  CONCLUSIONS
  Permanent retention is increasingly being recommended as the only way to ensure long-term stability of an orthodontic treatment result. Dental practitioners should be familiar with the rationale for retention and the design of the appliances worn by the their patients.
