Originální abstrakt

The aim of presented work is to compare two different ways of prescribing a boundary condition of muscles and chewing force. The first variant of boundary condition considers muscle forces and their direction taken from literature. The second variant of boundary condition considers muscles modeled as finite elements and connects lower jaw and skull together. In the second variant a Youngs modulus of muscles changed in range from 1e4 MPa to 2,1e5 MPa. Models of living tissues were created on base of computed tomography (CT) images and modeled in 3D CAD software SolidWorks. Calculations were computed in the finite element software ANSYS. Material models were considered as homogenous, isotropic and linearly elastic for all parts. First, both variants of boundary condition were analyzed separately and after that, selected variables (as muscle forces and muscle direction scale factors) from both variants were compared together.
