logo 18 • CAMLOG Partner Magazine • July 2018 19 for vertical augmentation [6;7] was performed simultaneously on both sides. A micro drill was used to create a window in the thin bone in the area of the maxillary sinus. The facial window remained on the membrane and was carefully folded from the bone base after loosening the Schneider´s membrane and moved cranially. This created a free space which was then filled with a suitable augmentate (Cerasorb® by Curasan). The window was covered with a mucoperiosteal flap. The postoperative X-ray images show the sufficient augmentation of the entire maxilla in all planes (Fig. 9) prior to planned placement of six CAMLOG® implants in region 16/14/12/22/24/26 for a telescope-supported prosthetic restoration. Implantation Horizontal and transverse radiographs in the DVT prior to implantation showed good bone availability in the planned implant regions. The bilateral sinus lift offered sufficient bone height for implant lengths over 14 mm to achieve a favorable implant-crown ratio (Figs. 10 and 11). Frontolateral augmentation with retromolar bone chips guaranteed a proper sagittal abutment position in the critical front segment (Fig. 12), as the frontal and side view of the preoperative DVT (Fig. 13) before implantation shows. As planned, the six CAMLOG® Implants could be placed in the statically ideal Fig. 4: Clinical status prior to augmentation with clear centripetal atrophy of the upper jaw.
