To the Editor;
In the above article, we found that Table 6 was published incorrectly.
Table 6.
Comparison of programmed vertical tooth movements in ClinCheck®† among Angle’s Class I, II, and III groups of adult patients with anterior open bite treated by clear aligners without extraction
| Vertical movements | Planned movement | Actual movement | |||||
|---|---|---|---|---|---|---|---|
| Class I (n = 44) |
Class II (n = 16) |
Class III (n = 9) |
p-value‡ | Dental open bite group (n = 19) |
Skeletal open bite group (n = 50) |
p-value‡ | |
| U6 (mm) | −0.71 ± 0.52a | −1.45 ± 0.78bc | −0.79 ± 0.66ac | < 0.001 | −0.77 ± 0.53 | −0.93 ± 0.72 | 0.34 |
| L6 (mm) | −0.63 ± 0.56 | −0.48 ± 0.63 | −0.60 ± 0.54 | 0.54 | −0.42 ± 0.45 | −0.66 ± 0.60 | 0.13 |
| U1 (mm)* | 0.69 ± 1.00 | 0.49 ± 1.05 | 0.31 ± 0.37 | 0.48 | 0.80 ± 1.16 | 0.52 ± 0.86 | 0.29 |

Values are presented as mean ± standard deviation.
The minus sign indicates intrusion while the plus sign indicates extrusion.
U6, maxillary 1st molar; L6, mandibular 1st molar; U1, maxillary central incisor; L1, mandibular central incisor.
*Vertical movements of the incisors included only absolute extrusion/intrusion movements.
†Data collected from the first ClinCheck® (Align Technology Inc., San Jose, CA, USA).
‡Two-way ANOVA and Tukey post hoc test. Values with different superscript letters are significantly different (p < 0.05).
This should be corrected as follows;
