Özet
Objective The aim of this study is to compare the stress distribution along the alveolar bone following the allogenic and autogenous bone ring assisted immediate dental implant surgery using three dimensional finite element analyses Material and Methods Finite element models of maxilla and mandible that augmented with autogenous and allogenic bone ring graft with dental implant were created Vertical force of 100 N and oblique force of 100 N at 45(degrees) angle were applied to root formed design dental implant and abutment Results The highest calculated values of VonMisses (VM) stresses were observed in oblique loaded mandible model which augmented with allogenic graft In all models the highest VM stress values were greater for oblique loading compare to vertical loadings Allogenic bone ring grafts contribute the stresses more evenly through the implant, as for the autogenous grafts stresses are concentrated in the neck area of the implant Discussion Allogenic and autogenous grafts applied with implant placement create different stress distributions Stress distributions should be considered when choosing type of biomaterial.
