Abstract EN
The aim of this study is to investigate the stress distributions of different restoration options for class II mesio-occluso-distal (MOD) cavities.
A class II MOD cavity with proximal box gingival floor 1 mm below cementoenamel junction was designed in a mandibular first molar tooth model.
3D finite-element analysis (FEA) and 3D-CAD modelling were used to examine the occlusal stresses distributed to the remaining buccal enamel (RBE), remaining lingual enamel (RLE), adhesive surfaces, and restorative materials by direct and indirect materials resulting from a 600 N of static occlusal load stimulating foodstuff.
von Mises (VM) and maximum principal (Pmax) stresses were evaluated for two CAD/CAM materials and three direct materials.
CAD/CAM materials exerted less stress than the direct restorative materials.
Significant von Mises and Pmax stress value differences were seen among all restoration models on RBE.
Reducing RLE and including it into the cavity would be a more effective option for this model in this scenario.
As VM and Pmax stresses of PIHC CAD/CAM material for RBE and dentin were significantly lower than other tested materials, it may be the choice of material for indirect MOD restorations.
