Original abstract

The presented paper is focused on the stress – strain analysis of the restored tooth. For this problem computational modelling was chosen using the finite element method. The tooth is modelled from dentin and dental enamel with a class II cavity. The size of the dental cavity is considered in three sizes and three shapes. For restoration two types of filling materials were used. A physiological model of the tooth was created as well. Force was prescribed on the occlusal surface of the tooth. The analysis of results shows that from the different filling materials, and their interaction with the dental tissues, amalgam is from a mechanical aspect the best material for the restored tooth in the molar segment.

Prezentovaný článek je zaměřen na deformačně napěťovou analýzu sanovaného zubu. Tento problém byl řešen pomocí výpočtového modelování, konkrétně metodou konečných prvků. Zub je modelován ze dvou částí, a to dentinu a skloviny s kavitou druhé třídy. Kavita byla řešena ve třech velikostech a třech různých provedení tvaru kavity. Pro sanaci byly uvažovány dva typy výplňového materiálu. Pro srovnání byl vytvořen i model zdravého zubu. Z provedené analýzy vyplynulo, že z různých výplňových materiálu a jejich interakci se zubními tkáněmi je amalgám z mechanického hlediska nejvíc vyhovující výplňový materiál.
