Özet
Objective: The aim of this study is to compare the stress distribution of three different implant macro design applied with allogeneic cancellous bone rings using three dimensional finite element analyses. Material and Methods: Finite element models of maxilla and mandible that augmented with allogeneic bone ring graft with implants were created. Vertical force of 100 N and oblique force of 100 N at 45 degrees angle were applied to three different (variable thread, cylindrical, standard thread) macro design implants. Results: Stress concentrations in the conjunction of neck of the implant and allogeneic bone ring were higher than other areas. The highest calculated values of Von Misses stresses were observed in standard thread implant with oblique loading in mandible model. In all models the highest stress values were greater for oblique loading compare to vertical loading. Discussion: Implant macro designs shows different distributions to implanted bone or graft. It should be considered when choosing an implant in the cases augmented with allogeneic cancellous bone ring.
