On the Analysis of the Contact Conditions in Temporomandibular Joint Prostheses

Table 3

Elastic mechanical properties of the materials involved in the FEA [16].

Material	Elastic modulus E (GPa)	Poisson’s ratio ν	Yield stress σy (MPa)
UHMWPE	0.7	0.35	28
Cr-Co	210	0.3	550
Cortical bone	14.7	0.28

Yield stress of the cortical bone varies depending on the zone and is irrelevant for the study of the TMJR.
