Clear aligner therapy: a scoping review of treatment prediction, clinical effectiveness, and limitations
Available evidence, predominantly retrospective Level III–IV studies, supports over-correction strategies of 50%–100% for intrusions, 5°–15° for rotations and torque, and 1–2 mm for arch expansions; however, these estimates derive from heterogeneous, Invisalign-focused research and should not be applied as universal benchmarks.
