Advanced Layered Composites for Dental Applications
Šedivý, Zbyněk ; Kučera, Jaroslav (oponent) ; Štěpánek, Petr (oponent) ; Jančář, Josef (vedoucí práce)
PhD thesis deals with mechanical response of advanced layered composites for dental applications. Different composition of layers as well as different particle filled composites and fiber reinforced composites were examined under static three-point bending at room temperature. The results were correlated with the outputs of dynamic thermomechanical analysis (DMTA) and optical analysis (high speed video recording and SEM). Experimental data were used as a comparison with the results of analytical and numerical models in order to determine the best suited model for prediction of basic mechanical properties of layered composites. Based on these analyses, basic rules for clinical applications in dentistry such as minimally invasive bridges

Effect of adding multidirectional oriented fibers on mechanical properties of denture base resin
Kolářová, Eva ; Poláček, Petr (oponent) ; Pavelka,, Vladimír (vedoucí práce)
This Diploma thesis deals with effect of adding multidirectional oriented fibres on mechanical properties of denture base resin. Three sets of samples: PMMA resin, PMMA resin reinforced with Dentapreg Mesh and PMMA resin reinforced with stainless steel Mesh Strengthener were used for testing. Static three-point bending test and Charpy instrumented impact test were used to measure the behaviour of the samples under the static and dynamic loading conditions. Viscoelastic properties were determined by dynamic-mechanical analysis (DMA). Scanning electron microscopy (SEM) was used to characterize fracture surfaces. During the static loading of the samples the reinforcement does not play an important role in comparison with unreinforced resin. However, the opposite trend was observed under the dynamic loading where the effect to the reinforcement was increasing in the row PMMA resin – stainless steel Mesh Strengthener – Dentapreg Mesh.
