Modern methods of implant manufacturing by Rapid Prototyping technology
Dobešová, Lenka ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
The bachelor thesis is focused on modern methods of implant manufactuting by Rapid Prototyping technology. This research describes the possibilities of using unconventional technologies known as Rapid Prototyping methods. These methods make part of Additive manufacturing technologies. The advantages and the disadvantages of those technologies are discribed in this bachalor thesis, as well as comparison with CNC machinig. The project compares different powder materials for EBM technology. This research describes chemical composition and mechanical properties of those powder materials.

Thermal spray coatings of bioceramics
Kašpárková, Kristýna ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Bachelor´s thesis is focused on thermal spraying bioceramics. Bioceramic is designed to replace damaged parts of the human body. Practical use is mainly in orthopedics, jaw and facial surgery. This category of materials includes hydroxyapatite, which is characterized by biocompatibility and the ability to form a strong bond between the bone and the implant. The experimental part of the thesis was spraying 40 - pieces of dental implants for the company LASAK s.r.o. Plasma spraying technology was used to apply the hydroxyapatite coating. The required coating thickness was 60 m. The implant was sprayed and cleaned before spraying. Spraying was carried out in the laboratory of plasma coatings dental and skeletal implants ÚST FSI VUT Brno. A dimensional control was performed after plasma spraying.

Trends and forecasts in the technology of artificial disc replacement
Bodlák, Daniel ; Jelen, Karel (advisor) ; Říha, Michal (referee) ; Jíra, Aleš (referee)
1/1 škola: UNIVERZITA KARLOVA V PRAZE, Fakulta tělesné výchovy a sportu disertační práce: "Trends and forecasts in the technology of artificial disc replacement" autor: Ing. Daniel Bodlák datum: prosinec 2023 Abstract: The aim of the work was the study of current and new directions and trends in intervertebral disc replacement technology, a critical evaluation of current methods using implants for the treatment of degenerative disc disease, as well as a forecast of further development. The work also contains the related results of the collaboration on the optimization of the total "ball and socket" lumbar disc replacement within the project TA01010860 "Solving the problem of intervertebral disc replacement using modern knowledge, engineering methods and progressive technologies". In the part of the dissertation, focused on theoretical starting points, the attention is paid first to the intervertebral disc itself and its various aspects, from anatomy, through biomechanics and degenerative diseases, to the issue of implants for its partial or even total replacement. Subsequently, current trends and progressive methods of treatment are processed. The results section begins with a description of the methods used and then presents the results themselves, both from literature research and experimental work....

Biodegradable Mg-based materials for stents and bone implants
Zemková, Mária ; Král, Robert (advisor) ; Stráská, Jitka (referee)
The bachelor thesis is focused on the effect of mechanical processing rotary swaging (RS), specifically on the microstructure, mechanical properties and corrosion properties. The investigation was performed on the magnesium alloy AE42 with a different number of RS passes, which can be useful for medical applications. RS is more efficient and cheaper alternative to different material processing methods producing fine-grained struc- ture. Fine-grain structure with grain boundaries with high angle misorientation was achieved by this process. Microstructure was inhomogeneous - the grain size decreased from the surface to the center. An improvement of mechanical properties with the increase in the number of swaging steps was observed. Processing also led to a decrease in corrosion resistance in this alloy. Microstructure development was investigated by electron microscopy scanning. Development of mechanical properties was characterized by compression deformation tests and microhardness measurements. Linear pola- rization method was used for the interpretation of corrosion resistance. 1
