Abstract

Human Brain-Driven Digital Planning: Integrating TAD-Supported Mechanics into Clear Aligner Therapy

by D'Antò Vincenzo

Digital planning has changed how temporary anchorage devices (TADs) are positioned, from CBCT-based site selection to virtual set-ups and CAD/CAM surgical guides. Artificial intelligence (AI) tools now promise to automate CBCT segmentation, bone-thickness mapping and the identification of safe insertion sites, with gains in speed and reproducibility. Yet the orthodontist's planning rests on elements that algorithms do not fully grasp: the biomechanical goal, individual anatomy, and patient compliance. An anatomically safe site does not always coincide with the biomechanically most effective one: the optimal miniscrew position depends on the intended force vector and on the sequence of tooth movements planned within the aligner set-up, factors that stem from the clinician's therapeutic project rather than from anatomy alone. This presentation compares orthodontist-driven and AI-assisted miniscrew planning, arguing for a human brain-driven workflow in which AI supports as a safety and control tool, but never replaces clinical reasoning and professional responsibility.
