Aims: Bone structure around basal implants shows a dual healing mode: direct contact areas manifest primaryosteonal remodeling, in the void osteotomy-induced spaces, the repair begins with woven bone formation. This wovenbone is later converted into osteonal bone. The purpose of this study was to develop a model to accurately representthe interface between bone and basal implant throughout the healing process. The model was applied to the biologicalscenario of changing load distribution in a basal implant system over time.Methods: Computations were made through fi nite element analysis using multiple models with changing boneimplantcontact defi nitions which refl ected the dynamic nature of the interface throughout the bony healing process.Five stages of bony healing were calculated taking into account the changes in mineral content of bone in the vicinityof the load transmitting implant surfaces.Results: As the bony integration of basal implants proceeds during healing, peak stresses within the metal structureshift geographically. While bony repair may still weaken osteonal bone, woven bone has already matured. This leadsto changes in the load distribution between and within the direct contact areas, and bone areas which make latercontact with implant.Conclusions: This study shows that basal implants undergo an intrinsic shift of maximum stress regions duringosseointegration. Fatigue testing methods in the case of basal implants must therefore take into account this gradualshift from early healing phase until full osseointegration is achieved.
