Table 6. Results of in vitro validation analysis.

Average values and standard deviations for maximum (MaxPrin) and minimum (MinPrin) principal strain magnitudes recorded during three in vitro loading trials on the left P³ biting, the results of a specimen-specific in silico (FEA) loading analysis, and an estimate of the error in the FEA, where “error” is represented by the difference between in vitro (observed) and in silico (expected) results, divided by the expected results. See Figs. S3–S7 for site locations. Units are in microstrain (μɛ).
