Subperiosteal implants were first introduced in 1940 and then used worldwide for the treatment of edentulous maxilla or mandible with advanced bone atrophy.
With the advancement of digital technology for the fabrication of materials and the emerging of new materials, subperiosteal implants can be fabricated from a wide variety of materials, and there is a lack of evidence regarding which material could be suitable.

A 3D image of an edentulous maxilla bone will be derived from a computed tomography scan of an adult patient and saved as "stl" data. The solid geometry of the maxilla, including the cortical and spongious bone, was rebuilt from the "stl" data into the Digital Imaging and Communications in Medicine (DICOM) format with 3D-Doctor (Able Software Corp., MA, USA). With the Boolean method, force loading will be achieved between prosthetic parts, subperiosteal implant screws and bone tissues
