Planning prosthetics with zygomatic implants

A digital skull model based on CT data

“Improvement” of the solid model of the skull; conversion to FEM based model presetting both properties and boundary conditions, preliminary determination of the type and position of the implants

Calculation of SSS, determination of critical stresses and strains under an axial load of the “skull-implant-denture prosthesis” structure

Has the bone fracture criterion been met?

Correction dimensions of the implants

Yes

No

Calculation of SSS, determination of critical stresses and strains under the axial load of the “skull-implant-denture prosthesis” structure

Correction of the attachment points for the implants at the zygomatic bones

Has the bone fracture criterion been met?

Yes
