Linear regression analyses were performed to determine the overall correspondence
between FE and mean measured strains in all supports
) and the RMSE value of the measured strains is
1%. By separating the minimal strains from the maximal strain, relevant differences
can be observed. The other load configurations present similar results [

].
This study proved that FE models of the mandible can reproduce experimental
strains within an overall agreement level of 10%. The FE models correctly repro-
duced bone strains under different load configurations. For this reason, the FE model
The intercept value is small (6
