CATEGORY 62 AUSTRALASIAN DENTIST CLINICAL Fig 11: Implants installed Fig 13: Immediate panoramic radiography Fig 12: Straumann® Screw-retained Abutments installed workflow for full-arch rehabilitation demonstrated a streamlined and predictable approach, offering enhanced efficiency and reproducibility in routine dental practice. Clinical team feedback "The integration of the Straumann SIRIOS™ X3 scanner significantly enhanced the efficiency and precision of the full-arch rehabilitation workflow. This technology facilitated the streamlined execution of all critical steps involved in the Fig 15: Lower arch screw-retained abutments 3D scan Fig 17: Final prosthesis Fig 14: Lower arch 3D scan with Straumann EXACT™ scanbodies Fig 16: Final prosthesis Surgical procedure All implants achieved a primary stability with insertion torque exceeding 45 N·cm. For prosthetic rehabilitation, two Straumann® Screw-retained Abutments with a 30° angulation and gingival height (GH) of 3.5 mm, and two standard Straumann® Screw-retained Abutments with GH 2.5 mm were selected. Postoperative management included administration of Amoxicillin 875 mg and Spidufem® 600 mg to provide analgesia and reduce the risk of edema and crosscontamination. 0Figures 11–13. Prosthetic procedure Implant-Supported Prosthetic Rehabilitation Protocol. Following surgical intervention, was initiated utilizing the Straumann SIRIOS™ X3 intraoral scanner. The digital workflow comprised the following steps: u Intraoral scanning of lower arch, upper arch and bite to accurately capture occlusal relationship. u Extraoral 3D scanning of the intaglio of the lower prosthesis. u Intraoral 3D scanning of the lower arch with four Straumann EXACT™ scanbodies, each consisting of a BASE component secured to the abutments, with LINKS* subsequently affixed to the BASE. u Intraoral scanning of the lower arch without the scanbodies, with Straumann® screw-retained abutments and surrounding gingival tissues. u The resulting STL files were transmitted to the dental laboratory via the Straumann AXS™ platform. u A titanium bar was digitally designed and precision-milled for direct placement onto mini-abutments. u The final prosthesis was fabricated using additive manufacturing techniques, employing Straumann® P-Pro Resin and the Straumann CARES® P40 printer. Figures 14-17. Conclusion Aesthetic and functional restoration was successfully achieved following completion of the final prosthetic treatment. The entire rehabilitation process was completed over the course of four clinical appointments. The implementation of a fully digital immediate delivery of implant-supported prostheses. Notably, the combined use of Straumann EXACT™ scanbodies and LINKS components contributed to improved accuracy and procedural control throughout the digital workflow." Figures 18-20. u LINKS used in this case: V-form LINK (position 2); Short LINK (position 3); Angled LINK (positions 1 and 4), splinted with acrylic resin to ensure stability and allow occlusion registration with the upper prosthesis.
