What it is
Aligner force decays 40, 60% over the first 8 hours of wear. What that means for the 22-hour rule and for staging complex movements.
Why it matters clinically
Every treatment decision has a downstream consequence in aesthetics, stability, or cost. The core biomechanics live in clear aligners and tooth movement predictability; the commercial anchors live in treatment cost drivers.
Patient-side reality
Most patients meet this topic mid-consultation. The practical questions are always the same: what will this cost me in time, in money, and in follow-up visits? See ClinCheck planning for how the answers land in the treatment plan.
Evidence base
Numbers here come from peer-reviewed literature (AJO-DO, Angle Orthodontist, JCO), manufacturer multi-centre studies, or clinic audit data. Single-operator series and n<50 studies are flagged in the body, not cited as consensus.
Signals of a good decision
- The clinician can defend the choice in one paragraph without jargon
- The refinement policy is written before treatment starts
- The retention protocol matches the biomechanics of the case
- Cost, time, and compliance expectations are documented in the patient record
