Fig. 1. An initial panoramic radiograph that shows an extremely resorbed edentulous maxilla and a nearly edentulous mandible with a severely atrophic jaw in the right and left posterior areas.
Fig. 2. A panoramic radiograph after the placement of nine disk-design implants in a single surgery session.
Fig. 3. A Scanora (Soredex, Helsinki, Finland) radiograph of the left posterior maxilla after placement showing a multicortically anchored double disk-design implant.
Fig. 4. A Scanora radiograph taken after placement in the area of the tooth 47. It reveals a mono disk implant. Its bone support is tricortical.
Fig. 5. A radiograph of the implant-supported definitive restorations four years after implantation.
Fig. 6. The Hounsfield Scale applying a pseudo-color scale.
Fig. 7. An alignment image as an overall view of the skull and the arches with implants and definitive restorations.
Fig. 8. An axial image of the mandible with five titanium implants and two natural teeth anchored in the cortical bone.
Fig. 9. An axial image of the maxilla with five double disk-design implants. Fig. 10. A panoramic image of the mandible that demonstrates a well-corticalized mandible with implants, tooth roots, and supraconstruction.
Fig. 11. A panorama image of the maxilla that shows a poorly corticalized maxilla and five double disk implants anchored in a class IV bone.
Fig. 12. A cross-sectional view of the implant that comprises the shaft and the basal disk. It is shaped like an upside-down T. The disk is osseointegrated in cortical and trabecular bone. Bridgework is cement-retained on the implant abutment.
Fig. 13. A laterally inserted implant between natural-teeth abutments with two disks. The implant is osseointegrated in cortical and trabecular bone.
Fig. 14. The double disk implant is placed in the floor of the right maxillary sinus after a sinus lift procedure. The Schneiderian membrane lies on the basal disk. The implant is osseointegrated in the trabecular bone.
Fig. 15. A titanium implant with two disks ventral to the maxillary sinus. Hard palatine is visible. The implant is osseointegrated. The two disks are shaped like four circles.
Fig. 16. A double disk implant ventral to the left maxillary sinus. The implant is osseointegrated in the trabecular bone. The implant shaft is visualized. .
