Key Points

High-intensity occlusal contacts demonstrated the highest predictive accuracy in CAD-CAM workflows, correlating well with clinical markings.
In contrast, low-intensity occlusal contacts showed reduced accuracy and variability, especially in the posterior regions.
AI-assisted techniques can improve the workflow in occlusal devices, yet clinical verification remains essential during adjustments.
The findings underscore the balance between AI predictions and clinical evaluations for optimal device performance.

Implication

Cross-sectional analysis shows AI-assisted CAD-CAM accurately predicts occlusal contacts, indicating need for clinical verification.

Abstract

AI-assisted CAD-CAM workflows demonstrated progressively higher predictive accuracy as occlusal contact intensity increased, with high-intensity contacts showing the most consistent correspondence with clinical markings. In contrast, the reduced accuracy and greater variability observed for low-intensity contacts-particularly in posterior regions-underscore the continued necessity of clinical verification during device adjustment.
