Management of Severely Resorbed Jaws Using Subperiosteal Implants Restored with Implant-Retained Overdentures - A Case Report.

Despite significant advancements in dental care, edentulism remains the persistent challenge, particularly in cases of severe alveolar ridge resorption. Traditional treatment modalities, such as bone grafting and endosseous implants, are often associated with complications, prolonged rehabilitation periods, and patient dissatisfaction. The aim of this study is to introduce a novel technique for managing patients with severely resorbed ridges. This case report presents a 64-year-old edentulous female with severe jawbone atrophy, successfully treated using custom subperiosteal implants (SPIs) fabricated with advanced additive manufacturing techniques. The SPIs, designed based on the cone-beam computed tomography (CBCT) imaging, provided stable prosthetic support without the need for invasive bone grafting. The patient's treatment plan, included the placement of custom implants, implant-retained overdentures, and a 2-year follow-up, which revealed satisfactory functional and aesthetic outcomes with no complications. Advancements in SPI design, particularly the use of selective laser melting and finite element analysis, have significantly improved clinical outcomes and reduced the incidence of complications. This case highlights custom SPIs as a viable, minimally invasive alternative for the management of severely resorbed jaws, yielding satisfactory clinical results.
