About

Subperiosteal implants were first introduced in 1940 and then used worldwide for the treatment of edentulous maxilla or mandible with advanced bone atrophy.

Full description

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.
