Aligner Staging
The planned sequence of incremental tooth movements programmed into a series of clear aligner trays, each advancing the dentition toward the target occlusion.
Full Definition
Aligner staging refers to the digital treatment plan that determines the order, magnitude, and timing of tooth movements across successive aligner trays. Each stage typically moves teeth by 0.2–0.3 mm or 1–2 degrees of rotation. Editors reviewing treatment plans or patient letters must distinguish 'staging' from the total number of aligners, as the two are related but not synonymous. The term appears frequently in orthodontic software outputs (e.g., ClinCheck reports) and clinician correspondence. Incorrect use of 'step' and 'stage' interchangeably is a common editorial error in this context.
Usage
Usage note: Do not conflate 'staging' with 'attachments'; the latter are the composite buttons placed on teeth to assist aligner grip, which are separate elements within a stage.
