logo 18 • CAMLOG Partner Magazine • July 2018 15 mandibular counter model were mounted in the articulator and the two CERALOG® PEKK abutments of the occlusion were shortened accordingly. The crowns were to be splinted and screw-retained directly. The situation was scanned and the crowns were designed digitally and fabricated from zirconium dioxide. After stain firing, the crowns were finalized. Both the crowns and the PEKK abutments were activated and then bonded to the cast. A special focus was placed on the good hygienic ability of the implant crowns (Figs. 21 to 23). Overall, the two occlusally screw-retained crowns were fabricated without any problems. Despite the new materials and system components, this case with the CERALOG® System, which was new for us, was performed expertly and routinely by the dental technicians. Finally, the crowns were placed in the patient's mouth. A well-healed intraoral situation was present. The crowns were inserted and screw-retained with the titanium abutment screws and a defined torque of 15 Ncm. After the final functional and esthetic check, the screw access channels were sealed with cotton pellets and the Sinfony-Flow Composite (Espe). The patient was pleased, as was the treating team, about the very successful restoration (Figs. 24 to 27).
