Title: Subperiosteal implants in full mouth rehabilitation – Case report

Abstract

Subperiosteal implants are an effective alternative to long-term jaw bone augmentation in patients with severe atrophy of the upper or lower jaw. These implants are fully individualized and designed specifically for each patient according to the unique anatomical characteristics of their jaw. By eliminating the need for extensive bone grafting, subperiosteal implants significantly reduce treatment time and morbidity. One of the main advantages of this approach is that rehabilitation can be achieved in a single surgical procedure. The use of modern 3D printing technologies has further improved the precision, safety, and predictability of these implants, making them a reliable solution for the treatment of severely atrophic jaws. Subperiosteal (individualized) implants consist of a custom-made metal framework that is positioned directly on the remaining cortical bone and beneath the periosteum, the membrane covering the bone surface. The framework is fitted between the periosteum and the bony alveolar crest and is stabilized by the overlying mucoperiosteum. A threaded base supports transmucosal abutment posts, which carry a fixed prosthesis. These implants are fabricated from titanium alloy, the same biocompatible material commonly used in conventional dental implants. The present case report describes a medically compromised patient who required full-mouth rehabilitation using customized 3D-printed subperiosteal implants.

Audience take away from the presentation:
• Customized 3D-printed subperiosteal implants provide a viable and predictable treatment option for patients with severe jaw bone atrophy, especially when conventional implants and bone augmentation are not feasible.

• This approach allows full-arch or full-mouth rehabilitation to be completed with a single surgical procedure, significantly reducing treatment time and patient morbidity. 

• The use of biocompatible titanium (Ti-6Al-4V) and patient-specific design ensures optimal fit, stability, and load distribution.

• Subperiosteal implants are particularly beneficial in medically compromised patients, offering a safe alternative when extensive surgical interventions are contraindicated.
