A review study of abutments in dental implantology
Palkovič, Patrik ; Hájek, Petr (referee) ; Thomková, Barbora (advisor)
This bachelor thesis deals with the analysis of the influence of different types of abutments on the stress-strain states of the mandible with an inserted dental implant. The thesis focuses on two types of abutments, namely straight abutments and angled abutments. Furthermore, the thesis discusses the influence of bone tissue quality on the stress-strain states in the mandible with an inserted dental implant. Computational modelling using the finite element method (FEM) was used to assess the stress-strain states, specifically ANSYS Workbench software was used. Computational models of the mandible with dental implant were created with three abutment variations with different angles. Additionally, stress-strain states were determined for different bone tissue qualities. Analysis of the results showed that angled abutments lead to greater strain of the bone tissue and greater implant stresses compared to straight abutments. The influence of bone tissue quality on the stress-strain states was significant in terms of bone tissue strain. Bone tissue quality did not significantly affect the stress on the implant.

Design o the prestressed bridge structure
Schafferová, Denisa ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The aim of the master thesis is to elaborate a detailed design of the bridge structure. The structure is designed as a single-frame bridge with 2 spans with a total length of 55,7 m. The calculation of load effects is performed in Scia Engineer 22.0. The structure is examined for service limit state and ultimate limit state according to the valid European standards. MS Excel, IDEA StatiCa 23.0 and Beton FIN EC 2020 are used for the design of the cross-sections. The thesis contains detailed drawings of the designed parts.

D1 Reconstruction of Bridge on Motorway D1-212 in Ostrovačice, Preparation and Realization of Structure
Kratochvíl, Tomáš ; Kratochvílová, Erika (referee) ; Šlanhof, Jiří (advisor)
The diploma thesis deals with preparation and realization of D1 reconstruction of D1-212 bridge in Ostrovačice. It is a motorway bridge that transfers traffic over road II / 386. The reconstruction will demolish the superstructure of bridge with bridge equipment and parts of the abutments and their new construction. The preparation of the project solves the engineering report, the block plan drawing, the financial and time schedule - by objects, the budget SO 201, the study of the implementation of the main construction technologys, the project of the site equipment, the design of the main building machines, the SO 201 time schedule, a desigh of the bill of quantities for structure, technical note for superstructure of a bridge and control and test plans. Part of the preparation of the building is the processing of the emergency plan.
