Rapid Digital Conversion 2.0: A cast-less workflow for complete arch implant-supported restorations

Accurate data acquisition is essential for the efficiency and predictability of complete arch implant-supported restorations. Conventional and hybrid workflows often require multiple analog steps, such as cast fabrication, mounting, verification, or the use of reference screws with repeated scans. These additional procedures may increase complexity, prolong treatment, and introduce errors through multiple dataset merges. Rapid Digital Conversion (RDC) 2.0 represents a fully digital, cast-less workflow that eliminates the need for reference screws, physical casts, and intraoral verification jigs. In this protocol, the patient serves as the articulator and occlusion is established virtually. This video article demonstrates the clinical application of RDC 2.0 in a mandibular complete arch prosthesis. An anterior scanning device was fabricated from a sectioned immediate denture and connected to anterior multiunit abutments to capture the interocclusal record. The scan was completed with soft-tissue scan bodies, followed by a biocopy step and definitive alignment. The resulting dataset provided all information necessary for digital articulation, implant position integration, and interim restoration design. RDC 2.0 simplifies the restorative process, reduces chair time, minimizes potential errors, and enables accurate same-day or next-day delivery of interim restorations.
