Achieving an accurate fit in a complete arch screw-retained implant prosthesis is paramount, regardless of whether analog or digital impressions are employed. In the context of complete arch implant prostheses, using intraoral scanners has sparked significant debate. However, recent advancements in scanner technology, specialized scan gauges meticulously calibrated for precise recording, and the implementation of appropriate scanning techniques have substantially improved the precision and accuracy of digital records. The Nexus iOS scan gauge system represents a pioneering approach, seamlessly integrating these optimization strategies into a purely digital workflow to fabricate complete arch screw-retained implant prostheses in edentulous patients. This case report elucidates the fabrication process of a complete arch screw-retained implant prosthesis that exhibited remarkable fitting accuracy and streamlined the treatment process to a mere 3 appointments. The patient reported high satisfaction with the efficient timeline, aesthetic appeal, and functional performance of the prosthesis. A distinctive advantage of this technique is the notable reduction in treatment steps compared to traditional procedures.
