Abstract:

 

The objective of this study is to calculate the temperature and thermal stress distributions related to time as a
result of hot/cold liquid intake to the mouth utilizing finite element analysis (FEA). The crown models were
developed and analyzed using ANSYS software. In the first step of the study, the temperature changes under
thermal loading as a result of hot/cold liquid in the mouth were obtained depending on time. In the second step,
the thermal stresses produced by temperature changes were calculated. The distributions of temperatures and
thermal stresses were drawn for some critical nodes. The effect of different metal and ceramic substrates on
thermal response was considered. In the research, Ni-Cr alloy (NC) substrate experienced the highest values of
thermal stresses; comparatively the lowest stresses were calculated for Alumina core (AL) substrate. The values
of the maximum thermal stresses for Zirconia core (ZrO2) and IPS Empress 2 (IE 2) were very close, but the
values of it used IE 2 was smaller that ZrO2.
