Özet
Objectives: This study compared the accuracy of automated and manual measurements on digital model Bolton analyses performed using two clear aligner therapy (CAT) planning software programs. Materials and Methods: Digital intraoral scans of 40 patients undergoing CAT were analyzed. Mesiodistal tooth widths and Bolton ratios were measured using (1) the manual digital (MD) method via OrthoViewer software, (2) the ClinCheck system, and (3) DentOne software employing AI-based segmentation. The anterior and total Bolton values, as well as individual tooth width measurements, were statistically compared using nonparametric tests. The Kruskal-Wallis test was performed to compare differences, and the Mann-Whitney U test was used for post-hoc comparisons between groups. Measurement reliability was assessed using intra- and interobserver intraclass correlation coefficients (ICCs). Results: No significant differences were observed in the anterior Bolton ratios across groups (p > 0.05), whereas the total Bolton values showed significant differences between software and MD measurements (p < 0.05). ClinCheck showed smaller deviations from manual measurements than DentOne, particularly for maxillary molars and incisors. The largest discrepancies were observed in the posterior region. For teeth 26 and 16, the average deviations from the MD method were 0.56 mm and 0.47 mm for ClinCheck and 0.84 mm and 0.87 mm for DentOne, respectively. Conclusions: While the automated Bolton analyses performed by ClinCheck and DentOne are clinically acceptable, their measurements differ significantly from MD methods. These discrepancies are more pronounced in posterior teeth, likely due to anatomical complexity and limitations in intraoral scanning. Clinicians should perform intraoral scans carefully and consider manual verification when interpreting automated Bolton results, particularly for molars and crowded segments.
