Custom-made subperiosteal implants for atrophic maxilla rehabilitation: a digital approach

Introduction: Full-arch reconstruction with dental implants is considered the gold standard for dental rehabilitation. However, in cases of advanced maxillary atrophy, the placement of conventional implants may be unfeasible. Such situations can be managed using zygomatic implants or, alternatively, by placing subperiosteal implants. Observation: A 74-year-old completely edentulous woman with severe maxillary atrophy was treated using two subperiosteal implants. A provisional prosthesis was delivered 48 hours after the surgical procedure. Conclusion: Subperiosteal implant placement appears to be an effective alternative to zygomatic implants for the rehabilitation of the atrophic maxilla. This has been made feasible by the development of patient-specific virtual planning protocols.
