Abstract
Key Clinical MessageSubperiosteal implants might be the future first‐line treatment in patients with compromised alveolar ridges, although the use of proper techniques and pre‐surgical imaging is required to ensure treatment success.AbstractSevere bone loss puts the success of endosseous implants at risk. This technical report aims to introduce the subperiosteal implants (SPIs) created through additive manufacturing. A case study is presented, outlining the process and strategies employed to fully restore a maxillary structure using a customized subperiosteal implant. The patient, who had previously faced disappointment with traditional endosseous implants, received a customized SPI. A detailed 3‐year follow‐up is also provided. The design of the subperiosteal framework and abutments is based on digital records of the patient's jaw structure and a radiographic stent during occlusion. This ensures optimal placement within the dental arch. The implant and abutments are then three‐dimensional (3D) printed using a titanium alloy, while a provisional denture is 3D‐printed using polymer materials. SPIs offer a viable alternative for individuals with severe jaw bone degeneration, as demonstrated in this report detailing their application in complete maxillary restoration. This patient‐specific, prosthesis‐driven approach avoids the need for bone grafting and enables immediate functional recovery through a single surgical procedure.
