Patient-Specific Subperiosteal Implants 2.0 in Prosthetic Rehabilitation: Current Evidence and Limitations

Advanced atrophy of the alveolar process and extensive combined hard- and soft-tissue defects of the jaw following implant explantation or ablative cancer surgery substantially complicate fixed prosthetic oral rehabilitation. In clinical scenarios in which augmentation procedures or endosseous implant placement would be disproportionately extensive, or are not feasible, modified subperiosteal implants are re-emerging as a valuable alternative. Patient-specific titanium frameworks that accurately replicate the jaw anatomy enable immediate functional rehabilitation while reducing the overall invasiveness of the surgical approach. Short-term outcomes report high survival rates (95–98%); however, soft-tissue complications, particularly exposure and infection, remain frequent, and robust long-term data are lacking. The lecture summarizes indications, the surgical–prosthetic workflow, and the most common complications. The role of this technology within contemporary implantology is discussed.
