Abstract
Two variants of implant-supported overdentures (IODs) were investigated by quantitative computed tomography-assisted finite element method (QCT-FEA) on a patient-specific CTreconstructed model of human maxilla. The analyzed variants are bar-supported (splinted) and unsupported (unsplinted) implant assemblies. The loading was done by a 800 N force slanted by 30° in the buccolingual direction. The results of the analyses show favorable stress distributions for the bar-supported variant.
