OBSERVATIONAL
Conditions
Summary
Subperiosteal implants were first introduced in 1940 and then used worldwide for the treatment of edentulous maxilla or mandible with advanced bone atrophy.
Eligibility
Inclusion Criteria2
- 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 Criteria2
- A 2D image of an edentulous maxilla bone
- A non atrophied maxilla

Interventions
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
