A well-coordinated treatment concept and opti- mal interlocking product components are required. The presented case report explains how the in- terdisciplinary treatment team can combine these aspects. The case report shows how an implant (XiVE) is used in region 36 with a custom abutment (ATLANTIS) fabricated using CAD/CAM technology. Years of research and development have been invested in the implant design and surface, and the best possible outcome has been achieved in this Fig. 5b_Virtual wax-up of the abutment (ATLANTIS). Fig. 5c_View of the abutment design: The profile of the crown margin is exactly at gingival level. Fig. 6_The fabrication of the designed abutment in titanium was carried out at the Fabrication Center. Fig. 4 Fig. 3bFig. 3a Fig. 6 Fig. 5bFig. 5a Fig. 5c CAD0214_20-24_Bergmann 13.05.14 11:16 Seite 2
