In the rapidly evolving implant dentistry scenario, integrating digital technologies has significantly advanced the precision and efficiency of treatments, especially in full arch implant-supported rehabilitations. Despite these advancements, a completely digital approach to complex cases remains difficult and very challenging, necessitating a hybrid approach that utilizes both digital and traditional techniques. This technical note delineates a combined digital workflow for aesthetically guided, full arch implant-supported rehabilitations in the upper jaw, avoiding the need for interim dentures. Integrating a precise analogical plaster implant impression, advanced digital scanning and planning, mandibular movement registration (ITAK®), and face scans are possible by detecting a reference area defined by the palatine wrinkles. This approach aims to maximize aesthetic, functional, and biomechanical outcomes and addresses the ongoing debate about the accuracy of intraoral scanner scans versus traditional impression methods for full arch restorations. Although digital methods are increasingly favored for their efficiency and potential for trueness and precision, our procedure underscores the relevance of detecting an anatomical area as a reference. Through a detailed technical note, this paper showcases a reproducible protocol that combines the effectiveness of analogic plaster impressions with the benefits of digital planning and Computer-Aided Manufacturing, representing a step towards the future of implant dentistry where digital processes may fully supplant traditional procedures for the immediate loading and the further final prosthetic restoration, enhancing patient outcomes through more accurate and efficient treatment modalities

Abstract
In the rapidly evolving implant dentistry scenario, integrating digital technologies has significantly advanced the precision and efficiency of treatments, especially in full arch implant-supported rehabilitations. Despite these advancements, a completely digital approach to complex cases remains difficult and very challenging, necessitating a hybrid approach that utilizes both digital and traditional techniques. This technical note delineates a combined digital workflow for aesthetically guided, full arch implant-supported rehabilitations in the upper jaw, avoiding the need for interim dentures. Integrating a precise analogical plaster implant impression, advanced digital scanning and planning, mandibular movement registration (ITAK®), and face scans are possible by detecting a reference area defined by the palatine wrinkles. This approach aims to maximize aesthetic, functional, and biomechanical outcomes and addresses the ongoing debate about the accuracy of intraoral scanner scans versus traditional impression methods for full arch restorations. Although digital methods are increasingly favored for their efficiency and potential for trueness and precision, our procedure underscores the relevance of detecting an anatomical area as a reference. Through a detailed technical note, this paper showcases a reproducible protocol that combines the effectiveness of analogic plaster impressions with the benefits of digital planning and Computer-Aided Manufacturing, representing a step towards the future of implant dentistry where digital processes may fully supplant traditional procedures for the immediate loading and the further final prosthetic restoration, enhancing patient outcomes through more accurate and efficient treatment modalities
