Abstract :Aim: The aim of present study was to assess the stress distribution of different restorative materials applied in a Class V cavity by finite element analysis. Material and Methods: A 3D tooth model of a maxillary molar tooth was created for present study. The cavity was created in the computer model. Study groups were created according to four different restorative materials insert ignore into journalissuearticles values(Group I: a hybrid resin-based composite, Group II: a flowable resin composite, Group III: a compomer, and Group IV: resin-modified glass ionomer cement);. The von Mises stress distribution was evaluated loading of 400 N. Results: It was detected that the highest stress in Group II insert ignore into journalissuearticles values(301.21 MPa);.   However, it was observed that the lowest stress in Group I insert ignore into journalissuearticles values(235.74 MPa);. Conclusion: Within the limitations of our study, the lowest stress distribution for Class V cavity was obtained in the hybrid composite resin. Keywords: Finite element analysis, restorative materials, stress distribution SINIF V KAVİTELERDE FARKLI RESTORATİF MATERYALLERİN STRES DAĞILIMININ DEĞERLENDİRİLMESİ ÖZ Amaç: Bu çalışmanın amacı sonlu elemanlar analizi ile Sınıf V kavitede uygulanan farklı restoratif materyallerin stres dağılımını değerlendirmektir. Gereç ve Yöntem: Çalışma için bir maksiller sol birinci molar dişin üç boyutlu diş modeli oluşturuldu. Kavite bilgisayar ortamında hazırlandı. Dört farklı restoratif materyale göre çalışma grupları insert ignore into journalissuearticles values(Grup I: hibrid kompozit rezin, Grup II: akıcı kompozit rezin, Grup III: kompomer ve Grup IV: rezin modifiye cam iyonomer siman); oluşturuldu. 400 N’luk yük uygulanarak Von Mises stres dağılımı değerlendirildi. Bulgular: En yüksek stres Grup II’de insert ignore into journalissuearticles values(301,21 MPa); tespit edidi. Bununla birlikte, en düşük stres Grup I’de insert ignore into journalissuearticles values(235,74 MPa); gözlendi.   Sonuç: Çalışmamızın sınırları dahilinde, Sınıf V kaviteler için en düşük stres dağılımı hibrit kompozit rezinde elde edilmiştir. Anahtar Kelimeler: Sonlu elemanlar analizi, restoratif materyaller, stres dağılımı
Keywords : Finite element analysis, restorative materials
