3D printing of Li-Brushite/silk fibroin nanocomposites for bone regeneration.
(Third Party Funds Single)
Term: 1. April 2022 - 31. March 2024
Funding source: Deutscher Akademischer Austauschdienst (DAAD)Bone defects resulting from trauma, tumor removal or bone infections represent a major social challenge, exacerbated by the increasing proportion of elderly patients due to steadily rising life expectancy. The most effective treatment of such bone defects to improve the quality of life of those affected is therefore of high relevance. Despite the impressive progress in the development of synthetic materials for bone regeneration, some clinical problems still remain unsolved. Therefore, the aim of the proposed research project is the development of 3D-printed nanocomposites consisting of brushite cement and silk fibroin (SF), which show high potential to fulfill the structural and biological requirements of human bone and thus to regenerate bone.

Development of SiO2 – Li2O – P2O5 – ZrO2 dental glass-ceramic systems with extended lifetimes: crystallization mechanisms and resistance to subcritical crack growth
(Third Party Funds Group – Sub project)
Overall project: Dental glass-ceramic in the system SiO2 – Li2O – P2O5 – ZrO2
Term: since 1. October 2021
Funding source: Deutsche Forschungsgemeinschaft (DFG)Classes of materials that resemble natural teeth, such as polycrystalline ceramics, glass-ceramics and ceramic-methacrylate composites, have been preferred for tooth replacement for some time.
The first commercial product was based on a non-stoichiometric multi-component SiO2-Li2O-Al2O3-K2O-P2O5-ZrO2-ZnO system that was pre-crystallised, then melted and injected into a mould made of refractory material. The resulting glass-ceramics reached a degree of crystallisation of ~70 vol% with elongated Li2Si2O5 crystallites exhibiting very good mechanical properties.
The research approach makes it possible to determine relationships between the mechanical properties, composition and microstructure, either in the glass-ceramic or in the residual glass.
For this purpose, the influence of the SiO2/Li2O molar ratio on the crystallisation behaviour of Li2SiO3 and Li2Si2O5 phases is analysed and the effect of ZrO2 addition at constant SiO2/Li2O ratio on crystallisation kinetics and network structure of the residual glass is investigated.
