Beschreibungen/Notizen
Highlights • An accurate three-dimensional geometrical computer model of a human mandible was constructed from computed-tomography images. • Stress analysis in the mandible implant was performed by way of finite element simulations, with the geometrically characterized mandible and implant subjected to realistic muscular forces. • The location of implant failure correlated with the location of the highest stress concentration predicted by the numerical simulations. • Additive manufacturing, patient computed tomography and finite element simulations provide possibilities of significantly improved patient-specific design of implants of high structural integrity.
