Stress distribution in endodontically treated hypertaurodont mandibular 2nd molars restored with different postendodontic restorations by finite element analysis
Finite element analysis reveals that EverX Posterior restoration shows superior biomechanical behavior in hypertaurodont molars, indicating improved stress distribution.
Key Points
Evaluate stress distribution in hypertaurodont mandibular second molars with different postendodontic restorations.
Used Cone-beam computed tomography data to create a 3D tooth model.
Developed finite element models using MIMICS and ANSYS software.
Applied a vertical load of 350 N to the models to analyze stress patterns.
Model restored with EverX Posterior + Endocrown had the lowest stress values.
Ribbond + Endocrown model showed moderate stress concentration.
Gutta-percha + Endocrown model exhibited the highest stress concentration.
