Full digital rehabilitations on implants with TDC® technique: case series

Objective: This study aims to present a fully digital protocol—Total Digital Concept (TDC®)—for immediate loading full-arch implant rehabilitation utilizing a prefabricated definitive prosthesis, thereby eliminating the need for provisional restorations and reducing treatment time.Materials and Methods: A case series involving patients with terminal or edentulous dentition was treated using the TDC® workflow. The protocol integrates advanced digital technologies, including intraoral scanning, facial analysis, virtual diagnostic wax-up, and CAD/CAM manufacturing. Based on STL data from digital wax-ups aligned with 2D facial photography, implant planning was prosthetically driven. Surgical guides and final prostheses were fabricated preoperatively. Implants were placed using a fully guided approach, and definitive screw-retained prostheses were delivered within the same surgical session.Results: The digital-to-clinical translation showed high accuracy, allowing immediate delivery of pre-fabricated definitive prostheses without modification. No intraoperative complications occurred, and postoperative follow-up at 1, 2, 6, and 12 months confirmed the stability of both implants and prostheses. Patient satisfaction was high due to minimal appointments and immediate functional and aesthetic outcomes.Conclusions: The TDC® workflow demonstrates that full-arch implant rehabilitations with immediate loading and delivery of definitive prostheses are clinically feasible through a digital approach. This technique offers enhanced efficiency, precision, and patient satisfaction. However, despite its promising outcomes, current scientific evidence on fully digital full-arch workflows remains limited. Further clinical trials must validate its long-term predictability and broaden its applicability in routine implant practice.
