Ceramic materials applied in medicine - challenges and opportunities
 Vitásek, Ladislav ; Sláma, Martin (referee) ; Novotná, Lenka (advisor)
This thesis deals with ceramic materials applied in medicine, mainly in orthopaedics and dentistry. The first part is focused on requirements and current state of biomaterials in bone tissue engineering and their advantages and disadvantages. Composite materials, where ceramic material is one component at least, are mentioned in the next part. Dense ceramics based on alumina and toughened zirconia is described in the separate part. The main part of this thesis deals with porous ceramic materials based on calcium phosphates. There are also defined scaffolds requirements such as porosity, mechanical and biological properties and moreover processing methods. The experimental part of this thesis has been devoted to the preparation of bioactive porous ceramic material based on hydroxyapatite and silica with improved properties. Samples with different amount of silica in structure (6-21 wt%) were fabricated by polymer replica technique. Prepared scaffolds with structure similar to cancellous bone can be promising candidates for using in bone tissue engineering applications.
