CAD/CAM nitinol fixed (bonded) retainer vs Multistrand / spiral wire fixed (bonded) retainer: Stability: Little's Irregularity Index (lower arch)

Population
People who had received fixed appliance orthodontic treatment
Intervention
CAD/CAM nitinol fixed (bonded) retainer
Comparison
Multistrand / spiral wire fixed (bonded) retainer
Outcome
Stability: Little's Irregularity Index (lower arch)

It is very uncertain whether CAD/CAM nitinol fixed (bonded) retainer changes stability: Little's Irregularity Index (lower arch) compared with conventional/analogue multistrand fixed (bonded) retainer (very low certainty).

How reviews are matched to this question

Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
