Immediate surgical obturation utilizing a custom maxillary subperiosteal implant

Rigidly fixated custom subperiosteal implants (SPIs) have been reported in the literature for fixed retention of a prosthesis when there is limited or absent alveolar bone for placement of endosteal implants. Advances in digital technology and manufacturing have provided excellent adaptation and stability for this latest generation of SPIs, and the applications for this technique extend beyond fixed restorations of the partially or completely edentulous arch. In this case report, a modern patient-specific SPI was utilized to retain a surgical obturator without additional interdental or interosseous wiring.
