She has a fixed prothesis in the lower mandible, a removable upper denture and suffers from the inconvenience. The denture is supported by 4 implants with severe bone loss due to implantitis. Teeth #25 (13) and #26 (14) still remain.
The CBCT shows insufficient bone for implants under the sinuses. In the anterior zone there are four failed implants, which are not in a good enough position for a new rehabilitation.
