Biomechanical Effects of Digitally Constructed Subperiosteal Implants

Biomechanical Effects of Digitally Constructed Subperiosteal Implants From Different Materials With Different Prosthetic Superstructures on Atrophied Maxilla: A Finite Element Analysis

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.

Inclusion Criteria:

• A 3D image of an edentulous maxilla bone derived from a computed tomography scan of an adult patient.
• Maxilla with Cawood and Howell class 4 or 5 classification

Exclusion Criteria:

• A 2D image of an edentulous maxilla bone
• A non atrophied maxilla
