Fig. 10: Bone augmentation with Bio-Oss ® and Bio-Gide ® to increase the bone volume. The membranes were fixed with ALTApins. Fig. 11: Clinical situation prior to the third surgical interven- tion after 12 weeks. The occlusal view showed a healthy soft-tissue situation around the anterior im- plants. Fig. 12: Insertion of implants in the tuber maxillae. The surgi- cal stent supported by the four anterior implants was used to place the implants in an optimal position. Fig. 13: T he implants placed in the maxillary tuberosity. The precise surgical guide system using the precise CT data is necessary for the exact placement of the im- plants in the correct positions. Fig. 16: Bilateral sinus floor augmentation to obtain more ver- tical bone and achieve optimal implant stability. In- sertion of two implants (4.3 x13mm) in both sides. Fig. 17: In order to verify the exact positions and the depths, CT(3D)data were taken with the depth gauges dur- ing the surgery. Fig. 14: For precise insertion of the implants, a CT simulation is used to verify the axes and the locations in a three- dimensional view. Fig. 15: CT-simulation of the left side. Sinus floor augmentation Implant insertion in the mandible Fig.18: Removal of the mandibular titanium plates. Fig. 19: Insertion of five implants (3.8mmx13mm): three im- plants on the left side and two implants in the right mandible. Fig. 21: Postoperative situation. Fig. 20: For obtaining the necessary bone volume in the buc- cal side, bone substance was used and covered with the resorbable membrane.
