New AI system automates malocclusion grading using CBCT scans

Researchers have developed TeethGNN, a novel graph-based framework for automatically grading malocclusion from cone beam computed tomography (CBCT) images. This system bypasses manual measurements by directly predicting key morphological indicators and fusing them with image features using a graph neural network. A collaborative calibration strategy further enhances its robustness and accuracy. Experiments show TeethGNN achieves 77.08% accuracy and 89.61% AUC on a clinical dataset, outperforming existing methods and demonstrating potential for advancing computer-aided orthodontic diagnosis. AI

IMPACT This system could significantly speed up orthodontic diagnosis and treatment planning by automating a previously manual and time-consuming process.
