Retention Phase
The post-active treatment period in orthodontics during which retainers are worn to maintain tooth positions and allow periodontal and bone remodeling to stabilize.
Full Definition
The retention phase follows the active phase of orthodontic treatment and is designed to preserve the corrected dental and skeletal positions while biological reorganization of the periodontal ligament, alveolar bone, and surrounding soft tissues occurs. Retainers may be removable (e.g., Hawley retainer, vacuum-formed retainer) or fixed (e.g., bonded lingual retainer). The duration of retention is often described as indefinite, particularly for patients with a history of spacing or severe crowding. Editors should use 'retention phase' rather than 'retention period' or 'stabilization phase' unless the publication style specifies otherwise, and should ensure the type of retainer is specified in clinical records. Relapse is the primary risk associated with non-compliance during this phase.
Usage
Usage note: Preferred term is 'retention phase.' Specify retainer type (removable vs. fixed) in clinical documentation.

- "The manuscript described the retention phase as 'the stabilization period,' which the editor standardized to the preferred clinical term." — Copyediting note
