Objective: This study aims to analyze structural strength features (such as deformation and stress distributions) of polyether ether ketone (PEEK), glass fiber and zirconia post-core systems utilized in maxillary central incisor roots by means of finite element analysis (FEA).
Material and Method: The main geometry of maxillary central incisor considered in this study was obtained using an intraoral scanner. Other sub-components were modelled in a parametric computer aided design software based on the data obtained from the literature. Glass fiber, PEEK and zirconia were defined as post materials. 100 N force was applied with 45° angle on the palatal surface of veneered tooth in the FEA set up. The FEA was solved with linear material model and static linear loading assumptions through a commercial FEA code. Visuals and numerical results related to equivalent stress (Von Mises) and deformation distributions were interpreted.
Results: Maximum equivalent stress value of 32.76 MPa was calculated at the PEEK post-core. The maximum values for glass fiber and zirconia posts were 0.80 MPa and 21.17 MPa, respectively. Maximum equivalent stress values at the tooth roots in the glass fiber, zirconia and PEEK posts were 72.79 MPa, 69.01 MPa and 58.22 MPa respectively.
Conclusion: The stress magnitude experienced at the PEEK post-cores on the root was lower than glass fiber post and zirconia post. Regarding to this, although, it may be concluded that PEEK may reduce the complications that require tooth extraction in clinical practice, further researches are suggested including clinical trials.

Amaç: Bu çalışmada maksiller santral kesici diş köklerinde kullanılan üç farklı post-kor sisteminin (polieter eter keton (PEEK), cam fiber ve zirkonya) yapısal gerilme dağılımlarının sonlu eleman analizi (SEA) ile incelenmesi amaçlanmıştır.
Materyal ve Metot: Çalışmada, SEA için hazırlanan maksiller santral kesici dişin ana geometrisi intraoral tara-yıcı kullanılarak elde edilmiştir. Dişe ait diğer bileşenler, literatürden elde edilen veriler temelinde bilgisayar destekli parametrik bir tasarım yazılımı kullanılarak modellenmiştir. Post materyali olarak cam fiber, PEEK ve zirkonya ele alınmıştır. Kronlanmış olarak modellenen dişin palatal yüzeyine 45° açı ile 100 N kuvvet uygu-lanmış, analizler neticesinde, modeller üzerinde ortaya çıkan eşdeğer gerilme (Von Mises) dağılımları ve de-formasyon davranışına ait görseller ve sayısal değerler karşılaştırılarak değerlendirilmiştir.
Bulgular: Tüm analizler neticesinde en yüksek eşdeğer gerilme değeri 32.76 MPa olarak PEEK post-korda gö-rülmüştür. Cam fiber ve zirkonya postlar için gerilme değerleri sırasıyla 0.80 MPa ve 21.17 MPa elde edilmiştir. Köklerdeki maksimum eşdeğer gerilme değerleri karşılaştırıldığında zirkonya ve PEEK postlu modellerde sıra-sıyla 69.01 MPa ve 58.22 MPa cam fiber postlu modelde ise 72.79 MPa bulunmuştur.
Sonuç: PEEK post-kor modellenen kökteki gerilme değerinin büyüklüğü, cam fiber post ve zirkonya post model-lenen köklerden daha düşük elde edilmiştir. Bu durum, klinik pratikte diş çekimi gerektiren komplikasyonları azaltabilir olduğunun göstergesi olarak yorumlanabilir ancak bu konuda ileriki klinik araştırmaların yapılması faydalı olacaktır.
