Orthognathic surgery, traditionally planned using 2D cephalometric analysis and physical models, has evolved significantly with the advent of 3D imaging, digital simulations, and virtual surgical planning (VSP). This lecture will explore the transition from 2D to 3D planning in orthognathic surgery, highlighting the clinical implications, workflow transformations, benefits, and potential pitfalls of each approach. By contrasting conventional and contemporary methods, the session aims to deepen understanding of how digital planning enhances surgical precision, aesthetic outcomes, and interdisciplinary collaboration.
