Implant placement in severely atrophic jaws is especially challenging because of the poor quality and quantity of the future

implant bed. When there is a loss of teeth, atrophy of the alveolar processes occurs in a vertical as well in a horizontal plane. Restoring severely atrophied cases can be very challenging due to the proximity of the sinuses and nerves and the resorption of the alveolar crest. Usually bone grafts, mental nerve displacement and sinus lift procedures are used to overcome the initially poor anatomical and mechanical conditions of such cases. But severe atrophies may be rehabilitated within 10 days with a fixed denture thanks to the Cortically Fixed at Once (CF@O) approach. The CF@O protocol uses the remaining bone for fixing cortical implants. Its specificity is that no bone graft, no sinus lift and no nerve displacement are used. It uses specific designed plate implants, with a shape ranging from 41-43 mm in length. These solid titanium hybrid plates possess a high fatigue strength level with no welds or added parts. They are particularly indicated for mechanically demanding situations.
