Original abstract
The presented work is focused on stress – strain analysis of a reconstruction plate. For this problem the computational modelling was chosen with using finite element method. Mandible was created based on the methods of Reverse Engineering and CT images. Using these methods a STL model of mandible with cortical and cancellous bone tissue was created. A volume model of lower jaw with applied reconstruction plate was created in CAD software. A Symphysis fracture of lower jaw was modeled in calculation program ANSYS. The cancellous bone tissue is modeled with different mechanical properties, which corresponds to the varying quality of this tissue. In this work an influence of varying quality of cancellous bone tissue to von Mises stress is observed.

Předložená práce pojednává o deformačně napěťové analýze fixátoru pro dolní čelist. Pro řešení tohoto problému bylo zvoleno výpočtové modelování pomocí metody konečných prvků. Dolní čelist byla vytvořena na základě metod reversního inženýrství a CT snímků z nichž byl pomocí metod zpětné rekonstrukce obrazu vytvořen STL model mandibuly. V CAD/ CAM programech byla vytvořena soustava dolní čelisti s aplikovaným fixátorem. Dolní čelist byla uvažována z kortikální a spongiózní kostní tkáně. Spongiózní kostní tkáň je modelována s rozdílnými mechanickými vlastnosti, což odpovídá její měnící se kvalitě a je sledována změna rozložení a velikosti Ekvivalentního napětí HMH.
