Implant Overdentures in the Digital Era

Background: Advances in digital technology have transformed contemporary implant prosthodontics, offering new approaches to the design and fabrication of implant overdentures (IODs). Computer-aided design and manufacturing (CAD/CAM), additive manufacturing, and computer-assisted implant surgery have improved clinical accuracy, efficiency, and patient satisfaction. Understanding current digital workflows, manufacturing methods, and clinical implications as well as their limitations is essential to optimize treatment outcomes in IODs. Objectives: To provide a concise but comprehensive overview of the state of the art of digital implant overdentures focusing on the workflow, manufacturing, clinical outcomes, and associated complications. Conclusion: Digital technologies have improved precision and efficiency in removable implant prosthodontics. While CAD/CAM and additive manufacturing enhance fit and workflow, fully digital protocols still remain a challenge, especially in complex cases. Hybrid approaches combining conventional and digital methods currently provide the most predictable results, with future advances expected to expand clinical applicability.
