FEM and Von Mises Analysis on Prosthetic Crowns Structural Elements: Evaluation of Different Applied Materials

Figure 5

Different colors underline the stress distribution area related to the used material. The chrome cobalt alloy and the zirconium crown seem to better distribute the stress around the crown responding to vertical forces. (a) The zirconia crown distributes the stress in all the crown portions and areas even if a little stress is presented on the occlusal zone. ((b) and (c)) Chrome cobalt alloy and gold alloy guarantee perfect resistance to the fracture and a well distribution of the stress. (d) Dental resins show low resistance on fracture.
