Biodegradable bones implants based on Fe
Tkáčová, Tereza ; Míka, Martin (referee) ; Sedlaříková, Marie (advisor)
This thesis writes about biodegradable bone implants based on iron. The currently used metal-based implants have disadvantage in an often need of secondary surgery intervention to remove the implant. Therefore, there is a big research of biodegradable bone implants nowadays. In this work, iron-based materials with the addition of zinc and magnesium are being investigated. The produced samples have been immersed in a solution of NaCl and simulated body fluid, SBL. Subsequently there were regularly analysed changes of corrosion potential, pH, conductivity and also weight loss was watched.

Modern methods of implant manufacturing by Rapid Prototyping technology
Trubačová, Pavlína ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This research describes the possibilities of using unconventional technologies known as Rapid Prototyping methods. These methods make part of Additive manufacturing technologies. The project investigates the influences of process parameters on the final part quality and analyses the advantages and the disadvantages of using RP technologies for medical application, mainly for implant fabrication. The objective of experimental part is fabrication of samples by Selective Laser Melting (RP technology). The stainless steel will be used and two parameters will be varied (laser power, component inclination). For final evaluation of mechanical properties, surface quality, Alicona machine, compression test and Vickers’ hardness test will be used.

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.

Biodegradable bones implants based on iron
Hrabovský, Jan ; Zatloukal, Miroslav (referee) ; Sedlaříková, Marie (advisor)
This work deals with a current topic, which are biodegradable bone implants. These implants seem to be a suitable candidate for temporary fixations, with their gradual decomposition. An important parameter is not only the mechanical properties so that the material can withstand the load, but above all the corrosion properties and the degradation process. This work introduces the physiology of bone, trace elements and also describes current trends in the field of implants. The last part is a theoretical introduction to cross-stage processes. The practical part is focused on the preparation of iron-based samples with various dopants, subsequent annealing and analysis.
