Full-Arch Implant Rehabilitation: Conventional vs Digital Workflow - A Narrative Review

AbstractFull-arch implant rehabilitation has emerged as a predictable and transformative treatment modality for completely edentulous patients. Traditionally performed using analog workflows involving conventional impressions, facebow transfer, and laboratory driven prosthesis fabrication, the advent of digital dentistry has significantly altered treatment paradigms. Digital workflows incorporating intraoral scanning, CBCT guided implant planning, CAD/CAM fabrication, and 3D printing have enhanced precision, reduced chairside time, and improved patient comfort.This narrative review aims to comprehensively compare conventional and digital workflows in full-arch implant rehabilitation, analyzing clinical steps, accuracy, efficiency, prosthetic outcomes, cost considerations, and biological implications. Clinical evidence suggests that while both approaches yield predictable outcomes, digital workflows offer superior reproducibility, streamlined communication, and enhanced prosthetic accuracy. However, limitations such asequipment cost and learning curve remain relevant.Digital protocols represent a paradigm shift but should be integrated judiciously based on clinical expertise and case complexity.
