The digital revolution in orthodontics has transformed routine clinical workflows, transitioning traditional alginate impressions toward high-resolution 3D intraoral scans and automated digital model analysis.
As artificial intelligence (AI) platforms become increasingly embedded into diagnostic software, they promise unprecedented efficiency by automating complex calculations such as Bolton ratios, space analyses, and occlusal classifications.
However, despite rapid technological advancements, verifying the precision, reproducibility, and clinical reliability of AI-generated diagnostic outputs against established expert human standards remains a fundamental requirement for safe clinical integration.
A critical challenge in modern digital orthodontics lies in determining whether automated algorithms can consistently match the nuanced assessment of experienced clinicians.
While AI systems excel at rapid data processing, variation in landmark identification, crown segmentation, and tooth morphology can introduce subtle discrepancies in linear and categorical measurements.

Evaluating parameters such as overjet, overbite, molar relationships, and arch-length discrepancies is pivotal, as even minor measurement errors can cascade into improper biomechanical planning, incorrect extraction decisions, or compromised finishing stability.
This diagnostic accuracy study provides a rigorous comparative evaluation of AI-driven orthodontic software platforms alongside senior orthodontic specialists.
The findings reveal that while AI demonstrates high reliability and near-perfect agreement in categorical determinations such as Angle molar classification, significant variability persists in complex linear measurements and comprehensive Bolton analyses.
By highlighting both the current strengths and diagnostic boundaries of AI platforms, this research underscores the indispensable role of clinician supervision and offers vital insights for refining next-generation digital orthodontic algorithms.
