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 (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
(301.21 MPa).  However, it was observed
that the lowest stress in Group I (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 (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 (301,21 MPa) tespit edidi.
Bununla birlikte, en düşük stres Grup I’de (235,74 MPa) gözlendi. 

Sonuç: Çalışmamızın sınırları dahilinde, Sınıf V kaviteler için en düşük stres
dağılımı hibrit kompozit rezinde elde edilmiştir.
