[IO-10]Revolutionizing the Fabrication of Implant-Supported Complete-Arch Prostheses with Intraoral Scanners
*Yoshiatsu Tanaka1, Hajime Hirata1, Yoshihiro Tanaka1 (1. Tohoku/Hokkaido Branch)
[Introduction]
This case series demonstrates the utilization of intraoral scanners (IOS) and a digital workflow for completely edentulous patients requiring implant-supported complete-arch fixed dental prostheses (ISCFDPs). Written informed consent was obtained from all patients for participation and the use of accompanying images in this case series.
[Case Summary and Treatment Details]
Patients received immediate provisional restorations on the day of implant placement. After four months, interim ISCFDPs on intermediate abutments were verified to proceed with the digital workflow. Intraoral scans were obtained using the IOS system (Medit i700; Medit Corp), generating standard tessellation language (STL) files. Following verification of accurate and complete digital data, a virtual wax-up of the final prosthetic design was created using CAD software. Without relying on conventional silicone impressions, the definitive ISCFDPs were fabricated entirely through the digital workflow. Following clinical and radiographic evaluations, the definitive ISCFDP was placed intraorally. Written informed consent was obtained from the patient for this case presentation and accompanying images.
[Progress and Discussion]
Intraoral scanning plays a crucial role in the fabrication of ISCFDPs, simplifying the process, enhancing precision, and reducing the time required for both clinicians and dental technicians 1,2). By leveraging advanced digital tools, this approach demonstrates significant advantages over traditional methods in the prosthetic phases of implant-supported restorations.
