| Abstract: | Summary. Within these investigations a new monomer formulation – consisting of a biodegradable basis monomer, reactive diluents, fillers,
and an appropriate photoinitiator – was developed for the stereolithographic fabrication of bone replacement materials. In
the current paper we describe the testing of several acrylate based reactive diluents – having different functional groups
– concerning reactivity, biocompatibility, and mechanical properties. Polymers from tripropylene glycol diacrylate, propoxylated
glycerol diacrylate and tricyclodecan dimethanol diacrylate showed the most promising results regarding these 3 criteria.
Three-dimensional spongiosa-like structures were built by stereolithography using different monomers, fillers, and a suitable
photoinitiator. |
