Amaç: Bu çalışmanın amacı bir molar dişin stres
dağılımı üzerinde farklı faktörlerin etkisini sonlu elemanlar analizi ile
değerlendirmektir.
Gereç ve Yöntem: Çalışma
için bir maksiller molar dişin 3 boyutlu diş modeli oluşturuldu. Kaviteler
(Sınıf I ve Sınıf II) bilgisayar ortamında oluşturuldu. Kaviteler bilgisayar
ortamında üç farklı restoratif material ile (kompozit rezin, amalgam ve cam
iyonomer siman) restore edildi. Bu çalışma için iki termal yük (5 ºC ve 55 ºC)
ve iki mekanik yük (mekanik tekil yük-dik ve mekanik yayılı yük-dik)
kullanıldı. On iki çalışma grubu oluşturuldu. Von Mises stres dağılımı
değerlendirildi.
Bulgular: Restoratif
materyal ve mekanik yük faktörleri için gruplar arasında Von Mises stres
değerleri istatistiksel olarak anlamlı bir farklılık göstermezken (p>0,05),
kavite geometrisi ve termal yük faktörleri için gruplar arasında istatistiksel
olarak anlamlı bir farklılık vardı (p<0,05).
Sonuçlar: Çalışmamızın sınırları
dahilinde, en yüksek Von Mises stres değeri kavite geometrisi için Sınıf I
kavitede ve termal yük için 5 ° C’de bulundu.
Objectives: The aim of present
study was to evaluate the effect of different factors on the stress
distribution of a molar tooth by
finite element analysis.
Materials and Methods: A
3D tooth model of a maxillary molar tooth was created for present study. The
cavities (Class I and Class II) were created in the computer model. The cavities
were restored with three different restorative materials (resin composite,
amalgam and glass ionomer cement) in the computer model. Two thermal load (5 ºC
and 55 ºC) and two mechanical load (mechanical singular load-perpendicular and
mechanical distributed load-perpendicular) used in this study. Twelve study groups
were created. The von Mises stress distribution was evaluated.
Results: Von Mises
stress values were not statistically significant different among the groups for
restorative material and mechanical load factors (p>0.05) while there were
statistically significant differences among the groups for cavity geometry and
thermal load factors (p<0.05).
Conclusions: Within the
limitations of our study, the higher Von Mises stress values were found in
Class I cavity for cavity geometry and 5°C for
thermal load.
