• Abstract: Introduction: Orthognathic surgical planning is essential for the correction of dentofacial deformities, and is supported by anatomical and functional bases. Traditionally, conventional methods have been based on two-dimensional cephalometric analyses and physical models. However, the digital revolution has introduced three-dimensional tools that have integrated greater precision and efficiency into planning. Objective: This chapter seeks to explore the anatomical and functional bases necessary for successful orthognathic surgical planning, addressing the transition from the conventional method to digital technologies. Methodology: Review based on articles from the PubMed, LILACS and BVS databases. Studies within the theme, available in full and free of charge, in Portuguese, English and Spanish were included. Duplicates and out-of-scope studies were excluded. Results: The use of digital technologies, such as computed tomography, intraoral scanners and 3D planning software, has brought significant advances. These tools allow for a more detailed analysis of the patient's anatomy, facilitating the diagnosis of bone asymmetries and discrepancies. In addition, digital surgical simulators allow for the preview of the aesthetic and functional result, aiding in communication between the surgeon and the patient. In comparison, conventional methods have greater limitations in accuracy and data integration, which can generate larger margins of error. Conclusion: The transition from conventional to digital orthognathic surgical planning marked a significant evolution in clinical practice. With digital tools, it was possible to improve the accuracy and predictability of procedures, resulting in better outcomes for patients. The anatomical and functional bases, essential in any approach, are further explored and optimized with the support of emerging technologies, reinforcing the importance of adapting to innovations in the field of orthognathic surgery.
