Dr Diogo Viegas explores the evolution of chairside restorative dentistry, focusing on the transition from fragmented digital processes to modern, integrated ecosystems. Historically, CAD/CAM workflows were often hindered by complex, non-integrated systems that required multiple manual file hand-offs, which led to increased turnaround times and clinical frustration. Today, unified platforms like the iTero™ Design Suite consolidate intraoral scanning, design, and fabrication into a single, connected workflow. The integration of artificial intelligence further streamlines these processes by providing automated features like margin detection and initial tooth anatomy proposals, which reduces the learning curve for clinicians and significantly accelerates the delivery of same-day care.

Through several clinical case studies, the article demonstrates the versatile applications of this technology, ranging from 3D-printed occlusal splints and aesthetic mock-ups to milled definitive restorations such as endocrowns. For instance, a single-unit restoration that previously required multiple visits can now be completed in under 90 minutes, greatly enhancing patient convenience. The discussion emphasises that while 3D printing offers speed and material efficiency for complex geometries, milling remains preferred for definitive restorations requiring high mechanical strength. Looking forward, the author concludes that the continued integration of AI, cloud-based collaboration, and hybrid manufacturing will further improve the predictability and sustainability of chairside dentistry.
