Many studies have investigated the effect of different parameters of the endodontically restored tooth on its final strength,
using in vitro tests and model simulations. However, the differences in the experimental set-up or modelling conditions and
the limited number of parameters studied in each case prevent us from obtaining clear conclusions about the relative
importance of each parameter. In this study, a validated 3D biomechanical model of the restored tooth was used for an
exhaustive sensitivity analysis. The individual influence of 20 different parameters on the mechanical performance of an
endodontic restoration with prefabricated posts was studied. The results bring up the remarkable importance of the loading
angle on the final restoration strength. Flexural loads are more critical than compressive or tensile loads. Young’s modulus of
the post and its length and diameter are the most influential parameters for strength, whereas other parameters such as ferrule
geometry or core and crown characteristics are less significant. [-]
