Case in brief
A 53-year-old woman with a severely atrophic maxilla presented with advanced peri-implantitis involving multiple maxillary implants. After the affected implants were removed and the site had healed, a patient-specific titanium subperiosteal implant was designed from cone-beam CT data and fabricated using CAD/CAM technology. It was placed under conscious sedation to support a provisional prosthesis, then restored with a definitive titanium-composite hybrid prosthesis. The report describes favorable aesthetic and functional outcomes, with the digital workflow enabling anatomical adaptation and avoiding bone grafting.
What made this case unusual
The customized subperiosteal implant was used as a salvage option in a severely atrophic maxilla where conventional endosseous implant rehabilitation was not feasible.
Diagnostic / clinical pearl
In this single case, a patient-specific CAD/CAM subperiosteal implant provided an alternative for maxillary rehabilitation when severe atrophy precluded conventional endosseous implants.
