Evaluation of artificial intelligence-based cephalometric tracing versus semi-automatic and manual tracing
AI-based cephalometric tracing reduces variability, offers standardization, speed, and reproducibility. This study compared AI-based automatic, semi-automatic, and manual digital tracing methods using 120 pre-treatment lateral cephalograms, assessing 34 skeletal and soft tissue measurements. Findings show AI overestimates some skeletal values, while manual methods are more consistent. Semi-automatic provides a balance of accuracy and efficiency, suggesting clinical potential with refinement.

Skeletal Analysis
Methodologies
Soft Tissue
Insight: The automatic AI method consistently overestimated SNA angles by an average of 1.29 degrees compared to manual tracing, indicating a tendency to exaggerate maxillary protrusion. This highlights a critical need for validation and adjustment in AI algorithms for accurate sagittal skeletal pattern assessment.

SNA overestimation by AI vs. Manual
Insight: A comprehensive comparison of automatic AI, semi-automatic, and manual tracing methods reveals distinct advantages and limitations across various cephalometric parameters. While AI offers speed, manual provides consistency, and semi-automatic strikes a balance.
| Feature | Automatic AI Tracing | Semi-Automatic Tracing | Manual Tracing |
|---|---|---|---|
| Reliability for Skeletal Values | Tendency to overestimate, particularly SNA and ANB. Inconsistent landmark identification for Point A. | Balanced accuracy, manual correction minimizes errors. Practical for clinical use. | Greater consistency for vertical measurements (GO-GN-SN, Gonial Angle). |
| Efficiency/Speed | Fastest, fully automated. | Faster than manual, with expert oversight. | Time-consuming. |
| Accuracy for Dental Measurements | Mostly comparable with minor statistical differences (L1 to NB angle). | High agreement for inter-incisal angle. Minor differences in U1 to NA. | High agreement for inter-incisal angle. |
| Soft Tissue Analysis (Nasolabial Angle) | Significant differences (lower values compared to manual). Errors noted due to complex curvatures. | Improved accuracy over fully automatic, but still with potential for error. | Highest mean values, suggesting greater accuracy. Time-consuming. |
| Operator Variability | Reduced, but inherent inaccuracies in landmark identification. | Reduced through semi-automation, but still relies on operator experience. | Highest, prone to human error and interpretation differences. |
| Clinical Recommendation | Requires careful oversight, not yet fully dependable. | Promising balance of speed and precision, potential for widespread clinical use. | Gold standard for accuracy, but with efficiency drawbacks. |
Insight: The general process for cephalometric analysis, from image acquisition to clinical interpretation, highlights the interplay between automated and human-supervised steps, especially in semi-automatic workflows.

Clinical Interpretation & Planning
Insight: Automated AI methods show significant discrepancies in soft tissue measurements, particularly the nasolabial angle, due to challenges in identifying landmarks on complex curvatures.
AI Challenges in Soft Tissue Tracing: The Nasolabial Angle
Scenario: In a cohort of 120 patients, automated AI tracing consistently reported lower mean nasolabial angles (103.64°) compared to manual tracing (107.78°), a statistically significant difference (P<0.001). This discrepancy suggests that AI struggles with the nuanced curvature and identification of landmarks on complex soft tissue profiles. Manual methods, despite being more time-consuming, yielded results closer to clinical expectations.
Outcome: This case demonstrates that while AI excels in speed, its application to intricate anatomical structures like soft tissues requires further algorithmic refinement and careful clinical validation to prevent misinterpretation of facial profiles.
Implication: For orthodontists relying on AI for comprehensive facial analysis, supplementing automated soft tissue measurements with manual checks is crucial to ensure treatment plans align with patient aesthetic goals.
