Özet
Aim: The aim of this study was to compare the stressdistribution under artificial forces that simulate thebiting forces of the two different post types used inmaxillary anterior teeth that had complicated crownrootfractures and to determine the region where thestress occurred. For this purpose, a finite elementanalysis method was used.Material and method: In the study, Glass fiber post(Group I) and carbon fiber post (Group II) were usedto model tooth with complicated crown-root fracture,which would be horizontal in the cervical region of thefracture line. In the model, fractured teeth fragment(coronal and root fragments) were reattachment to bypost. The force of 100N was applied to the incisal ofthe teeth at 900angles to the groups (longitudinalaxis). Finite element analysis method was used toevaluate stress resulting from force and to obtain athree-dimensional model. Analyzes were done with theANSYS program (ANSYSRel.6.0, ANSYS Inc., Houston,TX, USA).Results: As the results of the analysis, the resistanceof glass fiber post against the forces was higher thanthe carbon fiber post. The stresses were concentratedmostly at the palatinal regions in group I and II.Conclusion: The rehabilitation of esthetic andfunctional for anterior group teeth with complicatedcrown-root fractures was favorable glass fiber postthan carbon fiber post.
