Table 1. Specimen data.

The volumetric bone mineral density (vBMD) was estimated based on the bone mineral content and volume of the elements of the FE meshes that did not have any nodes on the surface of the models in order not to include any cortical shell in the vBMD calculations.

Specimen	Level	Donor	Age (years)	Gender	vBMD (g/cm3)
