Abstract
The strength of all-ceramic restorations depends on not only properties of basic material but also
used ceramic material, substructure and upper structure connection, the thickness of crown,
design, and bonding technique of restoration. The purpose of this study is to analyze the shear
stress between the zirconia core and silica-based ceramic by using the finite element method.
Using 20-node structural solid elements, the shear stresses were calculated with the methods
of shear test and Schmitz-Schulmeyer test through 3-dimensional finite element method. The
commercial software Ansys (Ansys Version 11.0, ANSYS, Inc., Canonsburg, PA 15317, USA) was
used to create a three-dimensional mesh. There is no significant difference between the test
methods as a result of the force applied close to the bond interface. However, when moving away
from the bond interface, it is understood that there is a failure in higher tensile forces. It was
determined that there was no significant difference in the results when the force to be applied
in both the Shear bond Test and Schmitz-Schulmeyer tests was performed the near interface of
