Advances in CAD/CAM Technology for Chairside Restorative Dentistry: A Workflow Analysis

Résumé

Advances in computer-aided design and computer-aided manufacturing (CAD/CAM) technology have revolutionized chairside restorative dentistry, enabling streamlined workflows and enhanced patient outcomes. This study examines the evolution, integration, and benefits of CAD/CAM systems in chairside dentistry, focusing on their impact on efficiency, precision, and patient satisfaction. The workflow begins with digital intraoral scanning, eliminating the need for conventional impressions and providing highly accurate digital models. Advanced CAD software facilitates real-time design modifications, allowing clinicians to customize restorations to meet functional and aesthetic requirements. The CAM component, using milling or 3D printing systems, produces precise restorations in a single appointment, significantly reducing treatment time. Innovations in materials, such as high-strength ceramics and composite resins, further enhance the longevity and biocompatibility of restorations. This paper also explores the challenges associated with integrating CAD/CAM systems, including the steep learning curve, high initial investment, and maintenance costs. However, the long-term benefits, such as improved efficiency, patient comfort, and predictability, outweigh these challenges, making CAD/CAM technology an invaluable tool for modern dental practices. Future advancements, including artificial intelligence and machine learning integration, are anticipated to further optimize chairside workflows and improve outcomes. This review underscores the transformative potential of CAD/CAM technology in chairside restorative dentistry and its role in reshaping the standard of care.
