Biomechanical Effects of Digitally Constructed Subperiosteal Implants

Condition(s) studied

Investigational drug(s) / intervention(s)

Subperiosteal implant framework: 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

Study 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

Primary outcome measure(s)

• bone loss under the implants — 10-15 years
  amount of bone loss which appears on a modeling process, The modeling process will be completed using a three-dimensional modeling software. A three-dimensional mesh consisting of 556,365 nodes and 2972,897 elements with VRMesh Studio (VirtualGrid Inc, Bellevue City, WA, USA) will used in the program.
