Correction: Mechanical properties of thermoformed and direct-printed aligner materials after immersion in 37 °C water: a 14-day in vitro study

Correction to: Scientific Reports 10.1038/s41598-026-36723-8, published online 21 January 2026

The original version of this Article contains errors in Table 2, where the strain values were incorrectly labelled. Specifically, the values were erroneously reported as 0.1, 0.2, and 0.3 now read 1, 2, and 3, which correspond to the intended 1–3% strain levels used in the mechanical testing protocol. The corrected and uncorrected table appear below.

Incorrect Table 2:
