CATEGORY AUSTRALASIAN DENTIST 77 Photo courtesy of doctors Waldemar Polido, Wei-shao Lin and Dean Morton (USA) Figure 6: View of the final zirconia crown (zerion® UTML, Straumann®) on the printed model and in the patient’s mouth. The complete workflow was digital, with immediate implant placement and temporary restoration – based on intraoral and CBCT scans, 3D planning, software-based diagnostic wax-up and CADCAM fabrication. LINICAL Prosthetic versatility The TLX Implant System is an integral part of the versatile and proven Straumann® prosthetic portfolio. As in the BLX Implant System, the TLX has also been equipped with the TorcFit™ implant-abutment connection optimized for digital workflows. This interface allows easy placement of abutments at soft tissue level and, alternatively, easy handling of direct-to- implant restorations. Screw-retained solutions facilitate retrieval e.g., for maintenance, and reduce concerns about peri-implant inflammation. Based on the open CADCAM platforms, either validated Straumann® or external workflows can be realized. This relates to both single-gap (Figs. 4-6), partially edentulous and full-arch (Figs. 2, 3) implant-retained restorations, in both straightforward and advanced cases. u About the author: Jan H.
